Self-illuminating fabricated solid material objects

0001The present invention relates generally to self-illuminating objects and more particularly to self-illuminating, fabricated, solid objects embodying designs, greetings, or information in a choice of colors.

0002The background information discussed below is presented to better illustrate the novelty and usefulness of the present invention. This background information is not admitted prior art.

0003Examples of materials that can be fabricated into solid objects include cement, concrete, plaster, fiberglass, glass, and plastics, to name just a few. These materials may be fabricated into a solid by the setting (<i>i.e.,</i> the solidification or hardening) of a liquid or a suspension, by pressing a powdered material into a mold, or any similar known techniques. Fabricated solids can be shaped into a vast variety of objects from an artistically sculpted lawn or garden decoration to paving stones for a patio, walkway, or driveway. Historically, lighting for these surfaces has been mainly from spotlights or appropriately placed lights. There have been some attempts to provide self-illuminating fabricated solid objects, but most efforts in this direction rely on the presence of one or more cavities within the solid objects in which a light source system is housed. These cavities create a structural weakness and a place for moisture or other contaminants to collect.

0004An example of these illuminating solids include illuminating blocks that are to be used mainly on the periphery of walkways. The light source providing the illumination is placed within transparent, flexible, tubing-like material that is positioned within a recessed channel that is open to the top surface of the stone. To provide power to the light source, an electrical junction box must be inserted into a second, much larger cavity that opens to the bottom surface of the block. These systems, however, present several problems. To avoid moisture from reaching the lighting units, filler must be placed within the flexible, tube-like material around the light source. The filler, of course, also must be transparent so as not to prevent the light from emanating from the surface of the object. The rather large cavity required to house the power system creates a structural weakness within the fabricated solid object. The relatively soft, transparent material used as a surface cover creates additional problems. The soft material cannot withstand the damaging effects of both physical and chemical weathering to which it is exposed, nor can it stand up to the wearing effects of pedestrian or vehicular traffic. What is sorely needed is the means to provide a self-illuminating solid object having a surface that is impervious to the damaging effects of both physical and chemical weathering and impervious to the daily wear that occurs on surfaces on which people and vehicles move.

0005Other attempts to provide illuminating surfaces rely on wiring that must be embedded into a surface topping, such as asphalt or concrete, as the topping is applied. Cavities must be cut into the surface topping so that the wiring can be connected to a light producing assemblage that must be fitted into each cavity. This type of system use a soft, plastic-like material placed over the light elements through which the light can emanate, but this approach suffers from the same limitations of poor durability as discussed above. Additionally, these systems can only be used in the initial installation of a walkway or a roadway. What is needed is the means to provide for self-illuminating fabricated solid objects that can be used in new and previously installed walkways or driveways, or on any other type of existing hard surface, whether the surface is horizontal, vertical, or inclined.

0006While some of these attempts to provide for in-pavement lighting use LEDs (light emitting diodes) as a light source, they also rely on a system of optical lenses and prisms to direct the light. These lenses and prisms, however, result in glass or other transparent or translucent weak material being located on the surface of these rather complex housings. To avoid damage from overhead foot or vehicular traffic these units can only be placed on the edge of the walkway or driveway. What is lacking in the art is a homogenous solid matrix incorporating LED light sources within a fabricated solid object that can be used in new or existing walks or driveways and that will last for the life of the solid fabricated object.

0007Furthermore, there have been attempts to provide illuminating solid materials made in or conveying designs to meet almost any occasion, such as a holiday, birthday, seasonal event, wedding, birth, etc. These are limited, though, by the fact that they must be fabricated from clear transparent materials such as methylmethacrylate, Lexan®, acrylic, or the like. Moreover, these solid materials must be etched or grooved to disperse light from the light source that must be inserted into a cavity formed in the material. These materials are inherently soft in the sense that they would not be practical for use where they would be continuously exposed to harsh weather conditions or more than occasional physical wear and tear. There is still an unmet need for a means to provide for fabricated hard material objects having incorporated illumination that is durable under even harsh conditions and can be presented with almost any desired design, or multiple alternating designs, in almost any desired color.

0008Recently, solar powered stepping stones have been described. These, however, still rely on a sealed housing provided with a soft-material translucent lens through which the solar powered light can diffuse. The translucent material is preferably an acrylic resin which will not support heavy vehicular or pedestrian traffic. What is missing from the art are fabricated resistant solid material objects that are self-illuminating, wherein the power for the illumination is provided by solar power, and where the solar-powered object maintains its durability even under harsh conditions including the damaging effects of physical and chemical weathering and heavy vehicular and pedestrian traffic, and can be offered in almost any desired design in almost any desired color.

0009Recently stepping stone illuminating systems having a light source embedded within the material from which an object is made, have been described. While these systems are generally durable when exposed to the traffic expected when used as walkway or driveway building materials, they do not provide any means for replacing a worn-out, damaged, or imperfect light source. In the recently described systems, all optical fibers, electronic circuitry, and light sources are permanently sealed and permanently imbedded within the material used to form the object, such as a paving block. To replace a light source in this system, the entire block would have to be replaced. Because the electrical supply means extend outside of the block, this system also suffers from the disadvantage that the paving blocks must be installed over a compressible aggregate, such as finely crushed gravel, in order to provide for the external wiring. Although this system allows for the use of a variety of colored light sources, once a color for the lights in a given block is chosen, there is no way to change the color of the lights, such as from orange for Halloween celebration to red and green for a Christmas theme, without replacing the entire block. Furthermore, this system makes no provision for a choice of design of a given block such as the choice to change from a pumpkin to a Christmas tree - again, the only choice is to change the entire block.

0010Thus, it has been shown that all of the present known attempts to provide for a self-illuminating fabricated solid present problems that include solids that require chambers, grooves, channels, pockets or panels of significant size for housing a light bulb or other light source from which light is emitted through a soft material located on the top surface of the solid. Additionally, none of these devices provides for an illuminating fabricated solid object, such as a paving block or stepping stone that has the strength, versatility and functionality of a concrete block or stepping stone, that provides for a lighted surface that includes various colors, patterns, or designs of light which may cover either part or the entire surface of the block or stone, where the light source means may be directly connected to the solid, or, alternatively, where the light source may be indirectly connected to the solid, by way of a fiber optic cable, for example, to provide for a plurality of solid objects to receive light from just one or a few light source means, and where the light source means, the color of the light, and the design that is displayed on a visible surface can be changed or replaced easily and rapidly without having to replace the entire object.

0011In view of the foregoing, it is desirable to provide for self-illuminating, fabricated objects, such as self-illuminating paving blocks, building stones, or statuary that emit light of one or a plurality of colors from their surfaces while maintaining the strength and durability expected from a comparable non-illuminating concrete paver or stepping stone, and that can do so at low cost while being attractive in appearance, versatile, functional, and durable. Such self-illuminating objects should be able to be manufactured in almost any desired shape, with almost any design, or designs, in almost any desired color, where the colors, design, and light source means may be rapidly and easily changed or replaced without the need to replace the entire object assembly, where the fabricated hard objects can be used on either hard or compressible surfaces, as desired, and where one or a plurality of solid objects may receive light from one or a small number of light source means.

0012The present invention satisfies the heretofore unmet need for self-illuminating, fabricated, solid objects, such as self-illuminating paving blocks, building stone, or statuaries that emit light from their surfaces, while possessing strength comparable to a non-illuminating concrete, or other suitable material, paving blocks, building stones, or cast statues, providing for inexpensive to manufacture, self-illuminating fabricated solid objects, that are attractive, versatile, functional, and adapted to include one or more patterns of various colored light and where the colors, design, and light source may be rapidly and easily changed or replaced without the need to replace the entire object, and where the fabricated hard objects are useable on either hard or compressible surfaces, as desired. Self-illuminating objects made according to the teachings of the present invention require little or no maintenance.

0013The present invention achieves the above and more by setting forth novel self-illuminating fabricated solid objects, such as paving stones or statuary, wherein the objects have any known, or yet to be known, optical fibers embedded within, where one end of the optical fibers are exposed at a visually exposed surface of an object, and while second ends of the optical fibers are contained within, or operatively related to, a an open receptacle that is also embedded, either reversibly or permanently, within the object except for an end of the receptacle that is exposed at a surface of the object. The exposed receptacle end is adapted to reversibly receive or to be functionally related to a reversibly powered light source to achieve light transmission of light emitted from the light source through the fibers and to the ends of the fibers that are exposed on the visually available surface of the fabricated object. The self-illuminating objects also provide for illuminated colored patterns, seasonal designs, informational text, or advertising. A plurality of designs in various colors may exist on a single object to provide, for example, a plurality of illuminated seasonal patterns, lit in colors that are associated with the season. These durable objects have a long life as surface exposed fibers wear with the surface of the object and worn-out light sources are easily and rapidly replaced.

0014The self-illuminating objects are formed by casting, molding, or pressing, or any other method that results in the making of a fabricated, solid object. The objects can be made of any material having properties amenable to the final intended use of the self-illuminating object, such as concrete or cement if it is desired to manufacture self-illuminating paving or building blocks or stones. Cement or concrete, as well as clay, plastic, plaster, fiber glass, and glass may be employed to manufacture statuary, memorial stones, or name plaques, for example. The manufacturing material may be opaque, translucent, or transparent.

0015The receptacle can be of any shape that will accommodate a desired light source that is either directly connected to the receptacle or remotely connected to the receptacle, such as light that is transmitted through a fiber optic cable. The receptacle can be of any material that will provide for the degree of protection desired for fibers and/or a light source means that may be contained within, or otherwise operatively attached to, the receptacle. These choices will, of course, be dictated by the intended final use of the self-illuminating fabricated object and the environment into which the object(s) is placed.

0016The light source can be any known, or yet to be known, light source means. In the examples discussed below the preferred light source is a light emitting diode (LED). The light source means can be directly connected to a solid object or may be remotely connected via a fiber optic cable providing for a plurality of solid objects to receive light from one, or a small number of, remotely located light source means. The use of a light transmitting means, such as a fiber optic cable for example provides for a large display consisting of a large number of self-illuminating solid objects. The use of a light transmitting means, such as a fiber optic cable also provides the means to conveniently transmit light to a distant or difficult to access place, such as an upper story patio or a roof-top display comprising one or more self-illuminating solid objects. The light source may be powered by traditional AC electrical sources, electrical batteries, or other powering source, such as solar, wind, or chemically or organically derived energy. If a LED light source is employed, the system requires only low power, such as a 12 volt source and is thus economical to run and energy efficient.

0019It should be understood that the drawings are not necessarily to scale, for instance, aperture <b>30</b> is shown as a rather enlarged rectangle relative to the end of receptacle <b>22</b> that is accessible through aperture <b>30</b>. Aperture <b>30</b>, however, could just as well be depicted as an opening shaped to conform, in size and shape, to the outer surface shape of receptacle <b>22</b>. Also, fiber optic cable <b>70</b> may of any desired length, but is shown in shortened form for convenience. In certain instances, details which are not necessary for an understanding of the present invention, or which render other details difficult to perceive, may have been omitted.

0020Referring now, with more particularity, to the drawings, it should be noted that the disclosed invention is disposed to embodiments in various sizes, shapes, and forms. Therefore, the embodiments described herein are provided with the understanding that the present disclosure is intended as illustrative and is not intended to limit the invention to the embodiments described herein.

0021The present invention is directed towards a self-illuminating fabricated solid, such as a paving stone or statuary. The illumination is provided by having one or more optical fibers embedded within the solid object with one end of the fibers adaptedly exposed at the object's surface to provide for a desired design or pattern, which design or pattern is expressed by the light emitting from fibers exposed at desired places on the surface of the object, while second ends of the optical fibers are contained within a first end of at least one open receptacle that is also embedded within the object except for the opening at the second end of the receptacle, which opening is exposed at a surface of the object. The exposed open end of the receptacle reversibly receives at least one reversibly powered light source which mates with the fibers' second ends for the purpose of guiding light from the light source through the fibers to the surface of the fabricated object providing for multi-colored, self-illuminating seasonal designs or patterns, informational text, or advertising. A plurality of designs in various colors may be present on a single self-illuminated solid object. These durable objects have a long life as surface exposed fibers wear with the surface of the object and worn-out light sources are easily and rapidly replaced.

0022Turning now to the drawings, <b>FIGS. 1a - 1c</b> illustrate one exemplary preferred embodiment of the present invention. <b>FIGS. 1a</b> and <b>1b,</b> transparent perspective views of self-illuminating fabricated solid object assembly <b>10</b>, illustrate paving block <b>12</b> with self-illuminating text "HELLO" visible on the surface on the surface as shown in <b>FIG. 1a.</b> Paving block <b>12</b> comprises visually exposed surface <b>14,</b> base <b>16</b> and surface <b>18</b> having at least one aperture <b>30</b>. The transparency of the drawings allows for illustration of optical fibers <b>20</b> as they occur embedded within the matrix of the paving block. Also illustrated is embedded receptacle <b>22</b> having first end <b>23</b> and second end <b>25</b>. During the fabrication of solid object assembly <b>10</b>, optical fibers <b>20</b> and receptacle <b>22</b> are positioned within the initially liquid or otherwise malleable material, used in the formation of paving block <b>12</b>, so as to provide for one end of optical fibers <b>20</b> to be visually exposed on a surface of object <b>10</b> while the other end of optical fibers <b>20</b> are securely enclosed in first end <b>23</b> of receptacle <b>22</b>. Receptacle <b>22</b> is designed to prevent any damage to the light source, such as from lightning, static discharge, and over voltage conditions. Second end <b>25</b> of receptacle <b>22</b> is exposedly positioned in aperture <b>30</b> of receptacle <b>22</b> for easy accessibly after the paving stone is formed into a solid object. Positioned thusly, second end <b>25</b> is adapted for the reversible acceptance of reversibly powered light source <b>40</b> (see <b>FIG. 1c</b>) to provide for mating of light source <b>40</b> with the ends of optical fibers <b>20</b> that are enclosed in first end <b>23</b> of receptacle <b>22</b>. Light source <b>40</b> is illustrated with affixed means for providing power <b>46</b> to light source <b>40</b>. Mating light source <b>40</b> with the ends of optical fibers <b>20</b> that are enclosed in first end <b>23</b> of receptacle source provide means for light emitted from light source <b>40</b> to be guided from light source <b>40</b> to the ends of the optical fibers that terminate on the visually exposed surface of the fabricated solid object providing for self-illumination of the fabricated solid object.

0023<b>FIG. 1c</b> illustrates first end or light bulb <b>42</b> of light source <b>40</b> positioned for its reversible insertion into second end <b>25</b> of receptacle <b>22</b> so that the reversibly powered light emitted from light source <b>40</b> is brought into intimate contact with the second end of optical fibers <b>20</b> and, thus, caused to travel along the length of the fibers from the second end of the fibers enclosed in first end <b>23</b> of receptacle <b>22</b> to the first ends of fibers <b>20</b> that are exposed on a visible surface of a self-illuminating solid object.

0024A light source means may comprise a variety of light sources in a variety of operative configurations, A light source means may comprise a removable, replaceable plug-in LED (light emitting diode), as one example. Such an LED light source may be provided with the fabricated solid object or may be provided separately. <b>FIG. 1d</b> illustrates receptacle <b>22</b> having socket <b>48</b> where socket <b>48</b> may be adapted for directly or indirectly receiving a light source. For instance, socket <b>48</b> may be adapted for directly receiving a replaceable light source, which in this example is illustrated as an LED light unit <b>40</b> with light emitting means <b>42</b> positioned for reversible insertion into socket <b>48</b>. Light emitting means <b>42</b> may be connected to a power source via socket <b>48.</b> Alternatively, as illustrated in <b>FIG. 1e,</b> socket <b>48</b> may be adapted for receiving a fiber optic cable <b>70</b> that transmits light from a light source means, such as light emitting means <b>42</b> that is remote from the solid object. Light emitting means <b>42</b>, may be functionally connect to power source <b>46</b> by means of socket or receptacle <b>72.</b> In this example, a fiber optic cable could provide a means to transmit light from one light source emitting means to a plurality of solid objects.

0025As is well-known in the art, each of the sockets or receptacles and the parts of the light sources means that are inserted into the sockets may be fitted with a lock mechanism. There are many lock mechanisms, such as when the thing that is inserted has two small pimple-like features, sometimes referred to as keys that fit into "key ways" that are incised into the sides of the receptacles to receive the keys. The key ways are usually curved where the curve accepts the keys as the keys are rotated as the thing that is inserted into the receptacle is rotated. The curvature of the key ways also provides a lock into which the keys are firmly positioned. The locking mechanism may also comprise a spring mechanism, a push button mechanism, or other locking means.

0026<b>FIG. 2</b>, a non-transparent view of a self-illuminating fabricated solid assembly, shows a paving block according to the teaching of this invention as it appears ready for use. The ready accessibility of second end <b>25</b> at aperture <b>30</b> of receptacle <b>22</b> ensures that light sources may be inserted and removed easily and rapidly, as desired. As mentioned above, aperture 30 is not required to be as large as it is in the illustrations. It need be only as large as required to hold receptacle <b>22</b>. The illustrations are designed for clarity of explanation.

0027Light sources may suffer from usage or from age or may be defective as supplied. In any of these instances, a replacement of the light source may be necessary. In the invention as disclosed, replacement of a light source is accomplished rapidly and easily. The old light source is removed from receptacle <b>22</b> by a slight pull or tug. Once the old light source is removed, a new light source is easily and rapidly inserted into receptacle <b>22</b>. Alternatively, a light source may be in perfect working condition, but one may desire to change the color emitted by the light source. Any known light source may be used, but in the preferred embodiment illustrated, the light source is a LED, which is a low-powered light source and is inexpensive to operate. Traditional bulbs, if desired, may also be employed.

0028In the preferred embodiment illustrated, the power source is from a low power voltage source, or alternatively relies on the corrective action of a resistor and or rectifier and/or inverter, and on traditional wiring. The power source used to provide power to the light source, however, can be any known power source. For example, solar power is also contemplated as a power source.

0029The preferred self-illuminating fabricated solid object assembly <b>10</b> comprises block <b>12</b> cast from concrete, cement, or any other moldable material that will provide the properties desired for the block as described, or for any of other desired fabricated self-illuminating objects that can be made according to the present invention. The casting or molding material may be added to the mold after the optical fibers and the receptacle holding one end of the fibers have been arranged in the mold. If this is the manufacturing process employed, then it is at this time that the ends of the optical fibers that will terminate at the surface of the object are positioned so as to achieve the desired pattern that will be described by the light that will emanate from the fibers exposed at the object's surface. The fact that the self-illuminating fabricated solid comprises a negligible amount of void space from the addition of the fibers and the receptacle to the object, the resulting objects, such as a paving stone or block, retains properties that are comparable to those of objects that are cast or molded without the addition of the fibers and the receptacle. Regardless of the material used or method for making employed, any of the contemplated self-illuminating fabricated solid objects as claimed may be of virtually any shape, including interlocking, radius or traditional squares, spheres, and all other polygonal shapes, animal, people, imaginary characters such as angels, gargoyles, or unicorns, water fountains of any of the above and other designs, and so forth. In the preferred embodiment illustrated, the paving block <b>12</b> has a substantially square or rectangle shape and may, of course, include rounded corners and edges to prevent chipping. The cast or molded material may be colored in the manufacturing process by the addition of pigments to achieve almost any desired color. In addition, the top surface <b>14</b> of the paving block <b>12</b> may be sealed with any known transparent or translucent surface treatment to form a water resistant layer while preserving the illumination effect. Further, the paving block <b>12</b> may be manufactured having almost any desired surface texture and/or pattern, such as slate, cobblestone, brick, or the like. Thus, it can be seen that the present invention provides for a self- illuminated solid surface that is impervious to the damaging effects of both physical and chemical weathering and to the daily wear that occurs when the surface is subject to both pedestrian and vehicular traffic.

0030<b>FIG. 3</b> illustrates a self-illuminating fabricated solid object having a seasonal pattern created by the light emitting ends of the optical fibers that are exposed on the visible surface of the object. Nearly any desired pattern, design, numbers, or letters may be formed on the surface of an object.

0031<b>FIG. 4</b> illustrates a self-illuminating fabricated solid object having two seasonal patterns emitting light (see <b>24a</b> and <b>24b</b> for example) on its visible surface. Each pattern is formed by a unique set of optical fibers in working association with a related unique receptacle, such as <b>22a</b> or <b>22b.</b> In the example illustrated, one may insert an orange light emitting source into the receptacle that is operatively connected to the optical fibers whose visually exposed tips describe the pumpkin pattern, and at another time, one could insert a light source that emits green light into the receptacle that is operatively connected to the optical fibers whose visually exposed tips describe the holiday tree. During the time period in which one does not desired to display a specific pattern, the light source providing the light required for the pattern is simply removed from the relevant receptacle. If desired, a plug or cap may be inserted into the receptacle to protect it from any harmful environmental conditions. It is further contemplated that each self-illuminating object assembly may comprise a plurality of predetermined patterns on its visually exposed surface, as desired. It is also further contemplated that a regulating switch be used to alternate the power from one light source to another if a flashing or blinking display is desired. It is still further contemplated that a set of switches and/or timers are used to simulate motion, such as when a plurality of designs are on one object, or single designs on a plurality of objects, and where the on/off action of the power to the various designs creates an image of motion. This can be visualized, for example, as an arrow that appears to move toward an entrance way when in reality it is a series of self-illuminating arrows in a series of walkway paving blocks that are sequentially connected and disconnected to a power source by the regulating switches and timers.

0032When a series of self-illuminating solid objects, such as self-illuminating paving stones or blocks, are placed on unconsolidated, compressible material, such as sand or crushed stone, the wiring used to connect the system to a power source and the wiring that is used to interconnect the blocks, as well as any fiber optic cable that may be used to connect one, or a small number of, light sources to a plurality of solid objects, may conveniently be positioned within a layer of sand or crushed stone. If, however, it is desired to place self-illuminating fabricated solid objects on a hard surface, there is the problem of where to place the power providing wires. <b>FIG. 5</b> illustrates a means for placement of self-illuminating blocks on a hard surface. To accomplish this, each object, such as a paving block, that is to be placed on top of a hard surface comprises at least one beveled or notched base edge <b>50</b>. The beveled or notched edge provides a space just sufficient to accommodate any required electrical wiring. If there are a series of adjacent blocks, such as when the blocks are used to construct a patio floor, a garden walk, or a driveway, the small, but sufficient space created by the bevel or notch provides a protected conduit for any required wiring. The connective wiring is protected from the damaging effects of traffic or weather. In fact, because no wiring is exposed on the surface, self-illuminating blocks made according to this invention can be placed even on surfaces that are likely to suffer from seasonal snow plowing. Note, that, if desired, self-illuminating fabricated solid objects, such as blocks or stones, are just as amenable to installation in a vertical position to form a wall surface or a fence. In this instance, the wiring is also protected by positioning the wire within the protective conduits created by beveling or notching at least one base edge. The conduits provide not only for the physical and chemical protection of any required wires but provides for additional aesthetic appeal; <i>e.g.</i>, tucking the wiring in the grooves assures that the wiring is not exposed in an unsightly manner. The bevel or notch, like the aperture provided for the receptacle, is minimally sized so as not to reduce the strength of the block. Therefore, it can be seen that the present invention provides for a system that can be used on any previously formed hard surface, whether the surface is a horizontal, vertical, or inclined, as well as on unconsolidated materials, new or old.

0033As mentioned earlier, the self-illuminating fabricated solid objects may be formed into almost any desired size and shape and of almost any color to address any aesthetic. One popular use for concrete or cement is to prepare statuary, especially the statuary so coveted as lawn and yard decoration. <b>FIG. 6</b> illustrates a self-illuminating fabricated solid object in the form of a lion. Such statuary is often seen in the entrances to homes. Attractive in the daylight, such statuary is hardly, if at all, visible at night. In fact, it is conceivable that such statuary could pose a tripping hazard if approached in the dark. <b>FIG. 6</b> illustrates how an attractive piece of statuary can also provide for illumination at night. The eyes <b>26</b> of the lion are defined by light emitting optical fibers according to the teaching of this invention. Statuary made according to this invention provides a welcoming and safe beacon to a home's entrance.

0034The self-illuminating fabricated object described herein has a multitude of uses. An object can be used alone, such as using a single self-illuminating building block, to provide for self-illuminating house number signs and/or name plaques that are set into a building wall. In many cases, a plurality of self-illuminating, fabricated objects can be used together to construct large area or large volume, self-illuminating objects. For instance, if an object is shaped as a paving stone, the self-illuminating objects can be used to form walkways, driveways, walls, and fences. Such paving stones can be fabricated to any shape including squares, rectangles, circles or any other regular or irregular polygon. Alternatively the paving stones can be shaped to mimic naturally occurring pavers. When used in this way, these pavers have strength and endurance comparable to that of non-self-illuminating pavers. They can be walked over and can easily sustain the weight of most vehicles. Another novel use for this invention is to insert light source <b>40</b> into apertures other than those found in fabricated objects, such as apertures fabricated into columns, railings, steps, edge portions of porches and decks, window trim, doors, cupboard faces, molding, picture frames, furniture, and the like. Using the light source of this invention in this way is limited only by a materials inability to comprise apertures adapted for receiving light sources according to the teachings of the present invention. The aperture(s) may be arranged to reproduce or complement a light pattern or design in a near-by self-illuminated fabricated material object, such as the paving stones of a walk or driveway. Such a continuity of light, along the path traversed to a secluded entrance way, for example, would reduce the incidence of falls or missteps when approaching difficult to see steps, a turn in the walkway, or the like. Such a continuity of light would also act as a design element to induce, or invite, persons to follow the lights to enter a building, such as a shop or a nightclub.

0035As each of the at least one optical fiber is set into the fabricated solid so that only the first end terminates flush with, and thus is visible at, the visible surface of the object, the fibers are protected by the material into which they are cast. This means that the fibers will wear at the same rate as the fabricated material and, thus, could be expected to last the lifetime of the fabricated material object. Although the fibers and the receptacle by which the fibers are held are permanently sealed and imbedded within the body of the self-illuminating object, the light source, which is the only part of the assembly that might suffer with age, is removable and, thus, is easily and quickly replaced, without the necessity of replacing an entire object. Because of the low cost of the optical fibers, the light source, and standard electrical wiring, the cost to manufacture and maintain the self-illuminating objects is only minimally more than the cost of manufacturing and maintaining objects without the self-illumination assembly. Maintenance costs can be kept low by utilizing timers or photoelectric power or switches.

0036The illuminating fibers can be arranged to provide for nearly any type of desired patterns, designs, or informational messages. During low light hours, a self-illuminating paver or block could be used to warn people that a step must be traversed. The warning could be simply light emanating from a random pattern, a nearly solid bar of illumination, or by arranging the fibers to describe the work "STEP". Accordingly, the entrance to a drive way, house numbers, the name of a home's occupants, all can be self-illuminating utilizing a horizontal or vertical surface.

0037Light sources are available in a wide variety of colors. A neutral design or pattern can be made to reflect a holiday or a particular celebration by simply changing the color of the light source. Reds and greens can be used to celebrate a holiday such as Christmas, purple and yellow for Easter, red for Valentines Day, and so forth. The light sources are not expensive and are particularly easy to change so these special effects are easy for almost anyone to achieve. Additionally, most light sources, especially LED light sources are long-lasting and come in a large variety of colors that do not change or diminish with age or temperature.

0038When self-illuminating solid object assemblies are contemplated for use in a low traffic area, the object could be fabricated from a softer transparent or translucent material resulting in a vast number of light-emitting design options.
