p0002Lamps with magnetic attachment

p0003The invention relates to a lamp, a transformer for the lamps and lighting systems from lamps and transformers and especially lighting systems with manually insertable and removable light modules, so that the quantity, direction and / or the characteristics of the light emitted from the system light can be easily varied.

p0004Previously lamps, especially lamps, luminaires m are mechanically held and electrically contacted, for example by means of clips or sockets. However, it is disadvantageous that the mechanical support needed comparatively large amount of space and also a solution and reattachment of the light source is aufwandig especially with a large number of bulbs of light.

p0005Especially in modern lighting systems, it is desirable that the user can control the quantity, direction and the properties of the light emitted from the light system is very flexible. In theater scenes one is accustomed to be found a variety of lighting fixtures that light of varying national tensity which allows users to color and other properties to the groin. In retail environments often adjustable reflector lamps and track-lights are used to illuminate merchandise or expenses. In offices and living rooms usually track-lights are used to direct light to a determined work area, or for visual effects. Although these systems are flexible, they have drawbacks. Em disadvantage is that they are relatively large, and in the sense that the light fixtures are striking. In many applications, such as in a showcase for jewelry or other high-quality goods, it is desirable that the lighting system is as unobtrusive as possible. In applications where the appearance of the lighting system itself contributes to the overall aesthetic appearance, occur additional design and manufacturing costs. Em Another disadvantage is that these systems, although they are flexible, may be put einzu- cumbersome depending on the lighting requirement. In many cases the Leuchtenhalte- are ments relatively heavy. To move a lamp holder with a mechanical plug, add or remove a tool is necessary, and in some cases may even have a new electrical connection be necessary. Even in the case in which the lamp holder may be rotatably mounted, the base of the lamp holder is typically movable only in a single dimension. Finally, there is the drawback that these systems are relatively expensive.

p0006US 5,154,509, issued October 13, 1992 to Wulfman et al., Describes a low voltage track lighting system, in which the lamp holder is mounted by means of a magnetic force to the rail, and electric power by means of physical contact between the electrical wires of the rail and the bracket is directed by the rail for mounting. Wulfman et al. teaches a conventional light rail system, which means that a number of light fixtures is movably mounted on a linear rail. The light fixtures of Wulfman et al. are attached to a triangular brace. Electrical power is transmitted to the housing of the holder by means of electrical contacts of the bracket which are located on two sides of the triangular clip and at two sides of the right angle-shaped receptacle of the housing. The track and Leuchtenhal- expansions of Wulfman et al. have a purely functional design, ie for providing and directing light.

p00801 shows a sectional view m side view a lighting system 1 of an LED light source 2 and a partial shown exchanger 3 in the form of a base plate.

p0081The LED light source 2 has a bright white LED 4 on the light source, which is mounted on a housing 5 and is laterally surrounded by a reflector to Strahlfuhrung. 6 To power the LED 4 and an existing drive circuit 7 in the housing 5 for the LED 4 lead out of the housing 5 out mechanically flexible contact legs 8, each having a permanent magnetic foot. 9 The foot 9 thus serve both the electrical contacting of the LED light source 2 as well as its losbarer attachment. The unit comprising the housing 5 (with control 7), the LED 4 and the reflector 6 may also be referred to as an LED module 2a.

p0082The planar transformer 3 includes in a support material to 10 embedded electrical contacts 11,12, whose surface is released 13 and thus serves as an electrical contact surface and as an attachment surface for the foot of the ninth The contacts 11,12 shown have a different electric potential such that upon them from the lamps 2, an electric power is picked off for operating the LED. 4 The contacts 13 are designed in its function as an attachment surface 13 that the magnetic feet 9 can adhere flat against them. For this purpose, the contacts 11,12 preferably a permanent magnetic material; which has a magnetic polarity on the contact surface 13, which is opposite to a magnetic polarity of the corresponding foot. 9 The contacts 11,12 are polarized for alignment of the LED light source 2 to each other with respect to their contact surface 13 Contrary gensetzt magnetically. Thus, in the DC power supply of the contacts 11,12 may be a positive electrical potential of the left contact 11 with a positive magnetic polarity may be connected to the surface 13 and a lower electric potential of the right contact 12 (eg., Ground) having a negative magnetic polarity to the surface 13 may be connected. Accordingly, a foot 9 which is to be connected to a positive electrical potential, a negative magnetic polarity at its contact surface on; and a foot 9 which is to be applied close to a lower electric potential has a positive magnetic polarity at its contact surface. This ensures in particular in DC operation of the LED light source 6 a correct electrical polarity, as incorrect orientation of the LED light source 2 whose feet 9 and the contacts 11,12 repel each other and attract only the correct orientation. The magnetic polarity is with the symbols '+' or - located ''. Alternatively, the contacts of the carrier 3, or the feet 9 on a ferromagnetic material, in particular a ferrous material such as steel.

p0083This allows the LED light source 2 particularly simple and space saving can be contacted.

p0084The reflector 6 can be covered to protect the light emitting diode 4 by means of a transparent cover 14th The drive circuit 7 may, in particular in Wechselstrombe- drove his designed the contacts 11,12 as drivers for the LED. 4 The drive circuit 7 may further comprise various other functions, such as a dimming function, when activated the light strength of the LED 4 is selectively reduced. Another possible function is using color variable lamps changing the luminescent color of the light source, eg. As when using an LED color cluster of differently colored, individually ansteuerba- ren LEDs.

p0085The control circuit 7 has to activate the various functions on a receiving means 15 having a radio antenna for receiving wirelessly transmitted radio control signals. The receiving means 15 is communicatively coupled to the driving circuit 7, so that the drive circuit 7 may convert the control signals.

p0086The control 7 is also selectively addressable, ie, that it converts commands that have a matching ID code, and does not act on commands that do not have matching I- dent code. This allows LED lamps 2 or groups of LED lamps 2 with the same identity code can be manually assigned. In particular, groups of same-colored light-emitting diodes or lamps are selectively driven to another example, the color impression of the system, eg., By switching on and / or off of bulbs of certain color.

p00872 shows the exchanger 3 in a in comparison to the view of FIG 1 a wider neck with six contacts 11,12. The six contacts 11,12 are voltage source at a DC 16 connected to form a first set of contacts 11, which voltage source having a positive terminal of the DC 16 are connected, as well as a second set of contacts 12 which one with negative terminal of the DC voltage source connected 16th liable Each LED lamps 2 tet magnetically with its connections to a pair of Kontakren from the first group and the second group. The LED lamps 2 are thus connected electrically in parallel.

p0088With the transformer 3, a - not shown here - his drive circuit connected to control the related transformer 3 lamps. 2 Thus, this control circuit alternatively or additionally a dimming function are provided which energizes all contacts or a selected subset of contacts low. Em providing a dimming function on transmitter instead of the lamps has the advantage that a dimming means only one drive circuit is realized and thus particularly inexpensive. The tendency is to burden reduction advantageous to implement as many functions via a drive circuit of the support 3 instead of driving circuits 7 of lamps. The drives 7 can selectively operate by only control signals are implemented, which are intended for the particular bulbs. So like one of the lamps shown 2 provided on a tatscode with a specific identity data signal hm down- terdimmen the Bright, while another of lamps 2 does not respond to the dimming command. The control signals may, for. Example, be transmitted by modulation of Tragersignals. The drive then preferably has a corresponding data tenauslesefunktion on, z. B. a decoder.

p0089Alternatively, the contacts may be 11,12 also connected differently. Also, a different type are used by power supply, for. Example, an AC voltage source. In general, the transformer to be equipped with an appropriate power supply unit, for. Example, with a transformer for converting mains voltage into a supply voltage, optionally with the use of a rectifier.

p00903 shows the LED light source 2 of FIG 1, but which is now encapsulated by an encapsulant 17, especially special shed. Here, the encapsulation 17 is a substantially spherical contour with a flat underside. The contact surfaces 18 of the foot 9 of the LED light source 2 are free, that is, the contact surface 18 of the respective electrical terminal 9 is exposed in the flat underside.

p0091Em so encapsulated lamps 2 has the advantage that it can be applied as a bulk material on a support, in particular if the lamp has a low expansion. Because through the round basic shape, the lamps 2 rolls so long on the transmitter until it is seated on the flat bottom and is then held by the magnetic holding force on the exchanger. This is particularly advantageous when the magnetic polarity of the contact surfaces 18 of the foot is different and correlated with an associated magnetic polarity associated contacts of the carrier, such as described above. Because then it is ensured that the foot 9 only to appropriate contacts of the carrier up set, z. B. connected to different terminals of the (DC or AC) voltage source.

p0092Alternatively, the shape of the encapsulation is not restricted and may, for example, rectangular, disk-shaped or cylindrically zy be what let be achieved in particular by an appropriate casting. Encapsulation can be reached also by using capsule shells, but their assembly is comparatively aufwandig.

p00934 shows the LED lamps 2, as it adheres to a transmitter 19, which has two sets of contacts 20,21, between which a potential is applied. The shape of the single contact 20 of the first group is gitterformig, while the rectangular contacts 21 of the other group of the other potential are disposed in the interstices of the first contact 20th Of course, a rectangular shape not mandatory; Rather, the contact 20 of the first group can pe example be diamond-shaped, and so on. In other words, the electrical contacts 20,21 are grouped into two groups and arranged in a lattice pattern, wherein the lattice constitute a contact 20 of the first group and the surfaces enclosed by the grid contacts 21 of the second group, between contacts of different 20.21 groups, an electric potential can be applied.

p0094The LED lamps 2 shows the Kontaktbemchen 8 in geboge- NEN state in which the emission direction of the light source 2 has been individually aligned by the bend. As an alternative to the two Kontaktbemchen 8 can for example be used with a flexible thin tube a gooseneck, which carries or accommodates the electrical leads.

p00955 shows a transmitter 22 with concentric annular contacts 23,24, each one of two groups belonging to a potential difference between them, said contacts alternate 23,24 different groups, ie, that is, between two adjacent contacts can be applied an electrical potential is. In other words, the electrical contacts are grouped 23.24 m two groups and arranged in a ring pattern with an alternating arrangement of the contacts 23,24 of the two groups, wherein between contacts of different groups 23,24 an electrical potential is applied.

p00966 shows a transformer 25 with adjacently arranged strip-shaped contacts 26,27, each one of two groups belonging to a potential difference between them, said contacts alternate 26,27 different groups, that is, between two adjacent contacts an electrical potential can be applied , In other words, the electrical contacts 26,27 are grouped into two groups and arranged in a stripe pattern having an alternating arrangement of the contacts 26,27 of the two groups, wherein between Contacts 26,27 of different groups, an electrical potential is applied.

p00977 shows a transformer 28 with neigh- beard in both directions arranged square contacts 26,27, each one of two groups belonging to a potential difference between them, said contacts alternate 26,27 different groups, ie, that extended between two adjacent contacts 29,30 an electrical potential is applied. In other words, the electrical contacts are grouped 29.30 m two groups and arranged 29,30 of the two groups in a checkerboard pattern with an alternating arrangement of the contacts.

p00988 shows a transmitter 31 with a plurality of pairs of contacts 32,33, between which an electric potential can be applied. In other words, each pair on a contact 32 of a first group and a contact 33 of a second group, between group nuber border contacts, an electrical potential is applied. This arrangement has the advantage, with their high flexibility in the control of the contacts 32,33 is possible because each pair of contacts 32,33 clearly visible and in extreme cases may have an individual power supply, eg. As a constant current source , Then, an associated LED lamps for. B. do without their own control.

p00999 shows a transmitter 34 with a plurality of pairs of differently shaped contacts 35,36; 37.38 or 39.40. In other words, three pairs of groups are arranged in a same basic pattern on the carrier 34, the contacts 35,36; 37.38 and 39.40 each pair group have the same shape, which is different between the groups. This lamps of different types can be used, which can then be particularly specific groups controlled and / or supplied. So like the contacts of a first pair-group z. B. with the rectangular contacts 35,36, to a different power source with a higher supply voltage applied as the second pair-group with the triangular contacts 37,38. The third pair-group with the round contacts 39,40 may in turn be controlled differently and / or supplied from another source. Alternatively or additionally, the contacts of a pair-group may be coordinated with the connections of bulbs same radiation characteristic, z. B. to LED lamps of the same color. Then, by a group-selective activation of the contacts 35 to 40 one ne high luminance of a color can be adjusted individually. To exclude a misallocation of bulbs to contact pairs, the contact surfaces of the contacts and the associated connections may be formed so that they only fit one another.

As discussed above, a dielectric coating may be used 1031 (shown in more detail in FIG 11) to 1032 and 1034 isolate the electrically conductive paths from one another and from the base 1030th The electrically conductive paths 1032 and 1034 are formed of thin electrically leitfahigem material such. As copper foil. The base 1030 may be constructed entirely from a magnetic material such as iron, or of a non-magnetic material, such as plastic, in which one or more parts of magnetic material are embedded, may be formed. The magnetic material of the support 1012 may be a permanent magnet which attracts the magnetic material of the base 1030, or vice versa like the magnetic magnetic material of the base 1030 be a permanent magnet, which will attract magnetic material of the carrier 1012th In both cases, the magnetic attraction force between the light module 1014 and the transmitter 1012 of sufficient strength must be to keep the module in 1014 safely on Trager 1012 elections it rend the module is still possible, attached to the transformer 1012 away or it to be repositioned, namely manually without the use of tools or the need of permanent electrical connections.

p0103A flex circuit or flex circuit, the channels 1018 and 1020 includes like, as a carrier used 1012th The flexible circuit with pressure, thermally leitfahigem adhesive may be applied to any magnetic substrate material without dielectric treatment. The dielectric see Strong is provided by the flexible Schaltungsmateπal. This type of transducer is particularly well suited for attachment beneath a shelf or a cabinet made of sheet metal or Ahnlichem or to a flexible magnetic strip.

p010411 shows an enlarged sectional view of the lighting system 1010. FIG 11 shows the electric circuit of the light-emitting System to see 1010. As shown in FIG 10 is supplied electric power from an external source via electrically conductive channels 1018 and 1020th FIG 11 shows a channel 1018 in electrical contact with the electrically conductive path 1034 and a channel 1020 in electrical contact with the electrically conductive path 1032. The paths 1032 and 1034 are connected to lead wires 1036 and 1038 of the light source 1028th A dielectric coating 1031, z. B. an enamel electronic good, isolated the paths 1032 and 1034 electrically from one another and from the base 1030. Any number of conventional dielectric or resistance-coating materials such as enamel, glass, ceramic, organic electrically insulating materials or Glass / ceramic coatings may be used in conjunction with the present invention. A dielectric coating like with the use of magnets with high electrical resistance, eg. As ceramic magnets can not be needed. However, such magnets must also have an adequate thermal conductivity for its function as a heat sink aufwei- sen, as discussed below. In order to avoid the possibility of short-circuiting the Tragerkanale, the width w (shown in Figure 11) between the Tragerkanalen 1018 and 1020 should be wide enough to avoid that either the path 1032 or path 1034 simultaneously touches both channels, even if the 1014 module is rotated on transmitter 1012th

p0105Now FIG respect 12 a lighting system shown in 1050, in which the channels 1018 and 1020 m electrically isolated nucleic th 1052 and 1054 of the support 1062 are. The surface 1060 of the support 1062 may comprise a dielectric coating 1016 outside the grooves 1052 and 1054, to 1032 or 1034 to avoid an electrical contact of the paths to the exchanger 1062nd The dielectric material in 1056 and 1058 may be formed from any suitable non-conductive material, which may be the same or different than the material of the dielectric coating 1016th As discussed above, the dielectric material 1056 and 1058 may not be necessary if the paths 1032 and 1034 due to the Nichtleitfahigkeit of the carrier material, the grooves 1052 and 1054 surrounding, electrically insulated from each other.

p0106In the embodiments shown in Figs 19 to 21 the light source 1028 is preferably an LED. LED Lighting Modules are typically light, compact, relatively robust and inexpensive. Erfmdungsgemaße LED embodiments are suitable mainly for a showcase in which the physical lighting systems are designed to be as compact and unobtrusive as possible. The transmitter may be thin, eg. As a thin stucco steel, with coating the dielectric loading is just below the electrical contacts. The lighting modules may have a low profile, so that the entire lighting system is ideal for applications m showcases. The transformer may be formed in or by a surface of a structure, such as a shelf board, a Vitπnenobersei- te, an underside of a cabinet, etc.. In a case where a carrier has an insufficient internal volume, is like a part of the devices or like devices for all electrical power and / or control of them nearby.

p0107The optimum voltage for operating a circuit with a plurality of LED light sources will depend on the number of light sources, their properties and arrangement in the circuit and other circuit components. The current may be dependent on the use DC or AC. In an LED light source amounts to the electric power that is applied across the terminals 1022 and 1024 of Figs 19 to 21, approximately five volts DC, but, as discussed below, may be desirable in some LED applications alternating current. In the case of tungsten / halogen lamps, such as MR- 16 lamps which are often used in track-lights, the voltage applied across the terminals 1022 and 1024 voltage is approximately twelve volts. In each of these Niedrigspan- nungsausfuhrungsformen there is no risk of electric shock from the exposed electrical channels 1018 and 1020th

p0108However, there are other types of light sources such as incandescent, tungsten / halogen and fluorescent, the scope of the invention. Em-down transformer may be used to reduce the voltage applied across the terminals 1022 and 1024 voltage, if necessary, such as in a conventional WoIf- ram / Halogen track-light. In Hochspannungsausfuhrungsformen the lighting system may be mounted in a housing with a light is permeable cover which 1018 and 1020 prevents access to the exposed channels, preferably with an emergency stop button which automatically via the channels 1018 and 1020 turns the power off when the cover is open.

p0109Especially with LED embodiments of the base 1030 and the transformer are 1026 such that they act as a heat sink, which derives enough heat from the light emitting module 1028, to meet the thermal operating conditions of the module. In particular, the magnet serves as a thermal path for heat transfer to the substrate part of the carrier. The substrate is the effective heat sink.

p0110A wide variety of LEDs in all colors that are erfmdungs- PURSUANT suitable for use, is about Osram Opto Semiconductors Inc. 2650 San Tomas Expressway, Suite 200, Santa Clara, CA 95051, obtainable. LEDs of the DRAGON family are particularly well suited.

p0111Referring to Figure 13 there is shown an alternative embodiment of a light source. The light source 1080 of FIG 13 may be 10 used for the light source 1028 of FIG by the lead wires are 1082 and 1084 electrically connected to the channels 1018 or 1020th The light source 1080 includes a cylindrical sleeve 1086 having a central axis AA. The re- reflector 1088, also having a central axis AA, mounted in the sleeve 1086th The reflector 1088 may, as shown m FIG 13, be parabolic, or have any other shape to provide a desired beam pattern. The reflector 1088 typically has a light-reflecting coating on the inner surface on 1089. The lens 1090 may be mounted by any suitable means detachably attached to the sleeve 1086, z. B. means of a thread 1092, so that the lens 1090 can be screwed into the sleeve 1086 in front of the light-emitting LED 1096, or by means of Aufsteckens two detents. As is well known from the prior art, the lens 1090 may be formed, patterned and / or coated to produce various properties of the light emitted from the light source 1080 light. Further, the lens may be dyed in 1090 so-that it matches the color of the light emitted from the light source 1080 light or different from. The lens 1090 may up to the outline of an alphanumeric character or other symbol be opaque or semi-opaque, so that the light source 1080 is projected the image of such a character-label or symbol when the light source is illuminated. Since the lens 1090 is replaceable, the property or effect of the light emitted from the light source 1080 light by means of replacement of the lens may be changed in 1090 with a different lens. In FIG 13, the light source, the LED 1096 uses 1080 as the light-generating device, but it may also be another light generating device can be used. (Not shown in the drawings) in an alternative embodiment of the invention may be the reflector 1088 removably attached to the light module, so that the direction of the emitted beam can be adjusted without re-position the light module on transmitter. See, for example US 5,154,509, issued October 13, 1992 to Wulfman et al. (Mentioned above), and US 4,719,549, issued January 12, 1988 to Apel.

p0112FIG 14 is a pictorial view of a wearer in 1100 for use with one or more light modules different according ferent aspects of the invention. The transducer 1100 is different from the transmitter 1012 of FIG 10 in that there are a plurality of pairs of electrically conductive channels, at which one or more lighting modules may be introduced magnetically displayed. In the drawing the channels 1102 and 1104 form a first channel pair, the channels 1106 and 1108 and a second pair of the channels 1110 and 1112, a third pair. If desired, additional pairs of channels may be Date added to transformer 1100th Each channel like a dark-nen, be formed electrically conductive material and attached to a body 1101 of the coating with a dielectric loading is reached, as shown in FIG 11, or each channel may be mounted in an insulated groove in the body 1101 as shown m FIG 12. The connections to be 1114 and 1116 state-connected gen with an external source of electrical power. The electrically conductive channels and / or channel pairs may be prepared by platinum techniques. In one embodiment, as shown for example in FIG 14 there is the advantage that a plurality of light modules on carriers may be attached, namely substantially in the form of arrays, ie, an array of rows and columns in the x- and the y-direction.

p0113The transmitter 1100 may comprise a variety of embodiments and applications. In a vertical orientation or orientation as shown in FIG 14 of the exchanger may be used in 1100 as an attachment for a signage. Lighting modules with alphanumeric lenses may be 1100 mounted to the transmitter that it display a message. If the transformer 1100 is mounted horizontally under a counter or in a display case, wherein the channels are facing down, the transmitter accepts a flexible arrangement of lighting modules, which positiomer- both the x and y directions are bar to light to a particular workspace or - highlight areas to be addressed, or to determine goods, possibly with different strong light, color or aesthetic effects. 21 shows an embodiment of the invention, which is mounted in a display case 1300th The display case 1300 includes a lighting system 1303 that is attached to the underside of an upper re galbretts 1302nd The objects 1310 that are on the shelf 1312 are objects that are exhibited behind glass 1314th The lighting modules in 1306 are attached to a transmitter 1304 to the objects 1310 to illuminate advantageous. The positioning of the modules 1306 is very flexible. As discussed with respect to Figure 14, the modules may be attached in various positions in both the x- and the y-direction of the horizontal tray. As already described with reference to FIG 13, reflectors 1308 are adjustable mounted on the modules 1306 so that light beams 1316 may thus be directed to illuminate objects in 1310 at a desired angle, and various properties of the emitted light like the choice of the lenses that are used at the reflectors 1308 (if any), can be obtained. Em additional pending lighting system 1303 may be attached to the underside of the shelf 1312 if objects are placed on the tray 1316 to be illuminated.

p0114Back to FIG 14, the transmitter may be used in 1100 as a Leuchtenhalte- tion with several tracks, which is mounted on a ceiling or wall. The exchanger 1100, preferably with a diffuse and protection end cover, like as a light cover support are used. In rooms with suspended ceilings of the exchanger may be adapted in 1100, instead of a ceiling panel to fit into the ceiling grid. In addition, like various exchanger 1100 of the same or a different size are used together as units or components, to form a two or three dimensional light-emitting system, for. Example, a two-dimensional m sys- tem shape of the letter "E", or a three-dimensional system m form a Wurfeis or a parallelepiped or Combinations thereof, wherein the lighting modules are attached to some or all surfaces.

p0115Em exchanger need not be rectangular. 15 shows one ne view of a circular Tragers 1120 based on the same wiring and Isolierungspπnzipien as in the transmitter 1100. In FIG 15, each electrically conductive channel represented by a single line rather than a dual line as shown in FIG 14 to the electrical circuit deutli- to show more. The drawing shows three pairs of channels 1122 and 1124, 1126 and 1128 and 1130 and 1132, which are arranged in substantially concentric circles on the dielectric surface 1134 of the support 1120th If the terminals 1134 and 1136 enabled with suitable electric power, like one or more light modules to be operatively attached to one or more channel pairs. In a variation of the embodiment of FIG 15, a single pair of channels in a spiral rather than in a pattern of concentric circles on the circular exchanger displayed introduced. It is within the scope of the invention, the exchanger 1120, and to modify the channels on its surface by their circular shapes m, various other shapes, such as oval, crescent, etc. drawn.

p0116Aspects of the invention are also applicable to three dimensions. FIG 16A shows a view of a spherical Tragers 1140 based on the same principles as in the wiring and insulation transformer 1100 of FIG 14. As shown m FIG 15, the electrically conductive channels in FIG 16A shown as single lines. The channel pair 1142 has the channels 1142A and 1142B; also made the channel pairs in 1144, 1146, 1148 and 1150 each of two channels. In this embodiment, the electrical circuit is completely constantly on the dielectric surface 1141 of the ball 1140. The channel pairs in 1142, 1144, 1146, 1148 and 1150 are in essence parallels the ball 1141. The circuit like by connecting the terminals 1152 and 1154 are activated with a suitable power source.

p0117To replace the light modules to the spherical exchanger 1140 Trageroberflache must be essentially flat. As used herein, "substantially flat" means that the Trageroberflache is either flat or has a sufficiently large radius of curvature, to allow the lighting modules to be mounted on the Trageroberflache by means of magnetic attraction diagrammatic without sliding or tipping. The distance between the channels of each channel pair should be small enough that a reliable electrical and thermal contact between the channels and the corresponding paths of a mounted light module takes place. In order to facilitate a reliable electrical and thermal contact between the Tragerkanalen and the corresponding paths of a mounted light-emitting module, the surface of the light-emitting module may be curved to conform to the curvature of the support. The term "essentially flat" as used herein with respect to a module surface, means that the module surface may be either flat or curved, so that the module by means of magnetic attraction can be placed without sliding or tilting on the Trageroberflache, although the curvature of the exchanger - and module surfaces need not be identical. Further, the Tragerkanale may be increased posted for the surface of the support, as shown in FIG 11, and / or the module paths like with respect to the engine be dulkorpers increased. Ask for additional may include the spring contacts module, typically of beryllium copper integration, which det, which may be shaped so as to conform to the curvature of the support. The spring contacts will improve the heat transfer away from the module and the Modulsrabi- LITAT improve especially where the path / channel contacts between the module and the transmitter are narrow. By means of employing a sensible combination of the aforementioned techniques may be configured in such a light module that it even reasonable safe magnetically to a transducer can be introduced when the surface of the support is curved.

p0118Although FIG 16A has a spherical exchanger shows the same principles for a cylindrical or conical exchangers and other curved three-dimensional transformer apply. In particular^¬ cially in the three-dimensional embodiments of the invention it may be advantageous to obtain the weight by means of employing a wearer, having a non-magnetic material such as plastic, said pieces of magnetic material in the transducers are embedded in or adhered to the inside of the support. In such embodiments, the composition of the embedded magnetic material must, however, be large enough to meet the heat sink function, and, as it must in all embodiments of the invention which use the maintenance mesenkenfahigkeit the magnetic material, the case is the Great of contact surfaces between the transmitter and the module may be sufficient to allow adequate heat transfer from the module to the transmitter.

p0119FIG 16B shows the same spherical exchanger 1140, except that the channel pairs 1142, 1144, 1146, 1148 and 1150 full width circuits on the dielectric surface 1141 of the ball 1140 is. In this embodiment, the terminals project in 1152 and 1154 m the interior of the carrier into 1140. In looking through the cutout m the drawing of terminal 1152 is electrically connected to the first channel of each channel pair, as shown by the connection wires 1156, 1158 and 1160th The terminal 1154 is any cable nalpaares electrically connected to the second channel, as shown by the connecting wires 1162, 1164 and 1166th Additional connecting wires to the remaining channels are omitted in FIG 16B for clarity. It is within the scope of the invention, the exchanger 1140 to be modified by being drawn in various other forms, such as an ellipsoid. In a variation of the embodiment of FIG 16A, a single pair of channels forming a spiral on the surface of the ball 1141, which runs from the North Pole to the South Pole substantially. The embodiments of Figs 16A and 16B are typically used m luminescent systems hung from a ceiling or attached to a rod-shaped base. For a light-emitting system that is directly attached to a horizontal or vertical surface, like one half of the carrier in 1140, ie, a hemisphere are used, and by using the same principles as those shown in FIGs 16A and 16B.

p0120FIG 16B shows the concept that electrical power may be supplied from the interior of the support of the lighting system to the Tragerkanalen. Various electrical control devices, such as ballasts, dimmer, transformers, power supplies, inverters, drivers, controllers, etc., to love also are in the body of the carrier, so that the lighting system directly to a standard power source, such as with 110 Volt AC, may be connected. Moreover, like those control devices in each case one or more lighting modules operate, such as a ballast, which serves four or eight fluorescent lighting modules. This feature of the invention, like three-dimensional Tragern, z. B. a cube, a sphere or a polyhedron are used, and it may with two-dimensional Tragern how the used shown in FIGs 10, 14 and 15, namely by the electrical channels are extended to the external terminals directly to the inside of my Tragerkor- instead, as shown in the drawings.

p0121In further aspects of the invention, FIGS 17A and 18A additional examples of embodiments of three-dimensional Tragern. FIG 17A shows a Ikosaedertra- ger 1180 with twenty same surfaces 1182, each of which is an equilateral triangle, as shown m FIG 17B. The terminal 1181, which has twice the electrically insulated wires, extending in the body of the carrier 1180 and provides a means for supplying electric power to the Lighting modules by ship of the carrier 1180th FIG 18A shows a Dodekaedertrager 1190 with twelve equal surfaces 1192, each of which is an equilateral pentagon, as shown in FIG 18B. The terminal 1191, which has twice the electrically insulated wires, extending in the body of the carrier 1190 and provides a means for supplying electric power to the lighting modules from inside of the support 1190 ready. As shown in the drawings, the electrically conductive channels like 1184 and 1186 centrally located on this lektπsch coated triangular area in 1182 as well as the electrically conductive channels in 1194 and 1196 on the dielectric coated pentagonal Flat 1192, although the nature of these channels m the triangular or pentagonal surfaces is not critical. The surfaces 1182 and 1192 have magnetic material, so that a light-emitting module can be attached to any surface. The channels 1184 and 1186 are electrically isolated from each other and from the area in 1182 as well as the channels in 1194 and 1196 of the Flat 1192. The channels 1184 and 1186 pass through the area in 1182 and are connected to the terminal 1181, the electric power from the inside the body of the Ikosae- changed ragers 1180 in the same manner as m FIG 16B may be supplied shown, and the same is true for the channels 1194 and 1196 from the inside of Dodekaedertragers 1190th

p0122Additional solid forms for transmitter in accordance with various aspects of the invention, such as cylinders, cones, prisms, combinations and Dull of different spatial structures, etc. may be constructed by a professional using the same principles as described above. These additional embodiments are within the scope of the present invention.

p0123As described in the previous examples, numerous embodiments and variations of Tragerstruktur are possible and practicable. In all these embodiments it is important that the electrical paths of the lighting module are properly positioned on the electrical channels of the carrier, so that the light module can be reliably fed. Images or graphics may be used to provide a guide for the correct alignment of modules at the transmitter. FIG 19 shows the lighting system of FIG 11 with additional surveys in 1206, 1208 and 1210 and a groove 1212. Assuming that the survey 1210 and the groove 1212 omitted, make the surveys in 1206 and 1208 ensure that the light module 1200 properly electrically is aligned when it is attached to the transformer 1204, possibly up to the electrical polarity. In a positioning of the survey in 1210 in the groove 1212 a correct polarity is ensured that the collection and groove, both located right of the center line BB in the drawing is not centrally located, the exchanger 1204th It is noted that the elevation 1210 and the groove 1212 need not always be necessary or desired, such as m the case where the light-emitting module 1200 is operated with alternating current.

p0124In a Gleichstromausfuhrungsform, wherein the light source 1214 is an LED and the collection 1210 and the groove have been 1212 omitted, a user has been noticed that the light module has been mounted in the wrong direction, and due to the fact that the LED, as it was turned on, has not lit, then the user has to install the light module again with the reverse polarity. Alternatively, the light module may comprise two LEDs, each of which is lit with different polarity so that ne LED lights were one, no matter what polarity the module. A light module with two LEDs opposite polarity will work with AC. Another double pel LED alternative is one that is emitted at the each LED differently colored light, for example, the first LED emits white light and the second with opposite polarity emits red light. The emitted red light could the user signaling that the light module with the wrong polarity is applied, or it may be a design feature of the lighting module that depends on its Polaritatsposition on exchanger or dependent can emit different colored light on the polarity supplied to the lighting system. The latter case may be used in a signaling lisierungssystem because the color of the emitted light, for. Example, red or green, can be changed by reversing the polarity supplied to the lighting system. Additional signaling options, such as flashing, could be achieved by pulsing the power supplied to the lighting system. A single light module may consist of two groups of LEDs, one group reacts to a first applied polarity and the second group responded to the opposite applied polarity, or alternatively may be a lighting system using two groups of lighting modules, wherein a group of modules on a first polarity responds and the second group of modules responds to the opposite polarity applied.

p0125FIG 20 shows the lighting system of FIG 12 with an additional survey in 1222 at the transformer 1226 and a matching groove 1224 in the light-emitting module 1228. The survey in 1222 is asymmetrical, while a vertical side (left side in the drawing) and a beveled side (right having side m the drawing), and the same goes for the matching groove 1224. Em attaching the module 1228 at transmitter 1226, the survey 1222 is properly positioned m the groove 1224 provides reliable electrical contacts and a polarity safe regardless of whether the groove is sawn aligned centrally to understand or handle the center line CC or not. There are numerous other possible arrangements of bumps, grooves and / or other means in accordance with various aspects of the invention, to ensure that the light module with reliable electrical contacts between see the module and the transmitter and, if appropriate, correct electrical polarity on transmitter attached becomes. In each of the foregoing embodiments of the invention, a variable number of lighting modules to a transmitter which is connected to an external power supply or a driver circuit may be connected electrically in parallel. Since the lighting modules can be Date added to or removed from exchanger at any time, the power supply must be able to regulate the operation of power so that each light module, an appropriate current is provided. Such regulated power supplies are known from the prior art. For example, see US 6,577,512, issued June 10, 2003. Tripathi et al., Which describes a current or power supply for a varying number of LEDs, which are wired in series or parallel.

p0126In an embodiment that uses a variable number of parallel-connected LED lighting modules, the driver circuit may benotigen the ability to detect the number of light modules mounted to the transmitter in real time. A resistor Added in parallel with the LED on each module, the ability of the drive module, to detect the number of mounted LED lighting modules anytime facilitate. Means periodic detection of the equivalent resistance of the mounted LED modules has been regulating the operating current in accordance with the driver circuit.

p0127Again posted the aforementioned patent to Wulfman et al. Like the present invention in low or high voltage applications with LED, incandescent, halogen or Leuchtstoffleucht- sources can be used, whereas Wulfman et al. Only a low-voltage halogen system teaches. Em exchanger of the present invention may be adapted to lighting modules m one to wear two or three dimensions, whereas the housing after Wulfman et al. on a linear rail are described restricts. An advantage of the present invention, which is not of Wulfman et al. is taught, is the feature that the magnetic materials in the transformer and in the light module dual purpose of attaching and Warmeabfuhrung xn serve LED embodiments. In applications where it is desirable that the lighting system is as inconspicuous as possible, such as a system running a counter for illuminating the goods, the bracket and the postures of Wulfman et al are. occupy much more space and be more conspicuous than a erfmdungsgemaßes lighting system, in particular, in one embodiment, uses the LED light sources. There are further advantages. The present invention may m sawn schilderungs- or signaling applications are used. Lighting systems according to the present invention may be used as components or units in larger lighting systems. Lighting systems according to the present invention may be prepared by three-dimensional Tragern, even providing an aesthetic appearance when the lighting system is not enlightened. The present invention has a much wider variety of applications than the lighting system of Wulfman et al. and provides the user with an improved ability to control the quantization did, direction and the properties of the emitted light ready.

p0129Thus, the present invention is not limited to the exemplary embodiments shown. So can be alternatively or additionally used to LEDs and halogen lamps are the. As LEDs, OLEDs are possible, in particular area OLED lamps. Thus, the contact legs can be 8 Date added subsequently in production or. at subsequent Hmzufugung they may be marked as an adapter piece that is at least at the module attachable and includes foot or even with these nachtraglich is to connect.
