Vehicle with transmitting and/or receiving apparatus

0001The invention relates to a lighting device, which in a body of a motor vehicle is secured with at least one lamp and a reflector in a Air space and the air space to the outside final glass shade and a transmitting and / or Receiving device for transmitting and / or receiving special Signal radiation, preferably electromagnetic Signal beams.

0002It is known, motor vehicles with additional instruments equip, the creation of driving aids for the serving driver of the vehicle or driving controls. Thus it is known, behind the windshield of a Motor vehicle an optical transmitter and receiver to arrange that for a continuous distance measurement preceding vehicles makes to at a small distance to produce a warning for the driver or even automatically throttle the speed. Also known are according to the radar principle working Distance measuring devices, which are also the measurement of distances preceding vehicles, as well as parking aids, etc. serve and therefore also on the rear of the motor vehicle may be attached.

0003The attachment of the known device behind Windshield to monitor the preceding vehicle Transport has the advantage that the windshield by the driver is cleaned with the help of the windshield wiper, when the view through pollution, rain, etc. is prevented. Naturally, this is of such devices Meaning, the emitted radiation, such as the optoelectronic equipment, due to contamination be scattered and / or attenuated in their intensity. Of the Disadvantage of this arrangement is seen in the fact that at the windscreen or in the region of the windscreen regularly mounted the review obstructing device must be, further hindrance in the passenger compartment can be. Moreover interfere regularly for the unit required transmission and / or receiving optics the aesthetic Impression of the vehicle.

0004From the generic FR 2,717,131 is a lamp apparatus for a Known vehicle in which a microwave radar integrated is. A device for generating the microwaves is in arranged a region of the lamp, in addition to the Reflectors located, in which the lamps are positioned. The cover glass of the lamp has in the area in front of the unit the microwave generating a Fresnel lens on.

0005From EP 526 524 A2 is a light generating unit known vehicles, in which an obstacle detection system is integrated, which in addition to the lamp reflector Lamp housing is arranged. It includes a receiver and a transmitter on. Here, the lens of the Obstacle detection system by an apparatus for Air cleaning be cleaned with.

0006The invention is therefore based on the problem, required transmitting and / or receiving devices be installed such, that impaired persons in the passenger compartment is prevented as well as a disturbance of the overall impression of the motor vehicle by the transmitting and / or receiving devices.

0007Based on this problem is a motor vehicle of the aforementioned type characterized in that the Transmitting and / or receiving device in the lamp space of a Illumination means is arranged so that by Lighting glass of special signal beam can be emitted is or can be received and that the air space by the lamp glass and the reflector is limited.

0008According to the invention, the transmitting and / or receiving device is thus in a lighting device, in particular a Headlights of the vehicle integrated. This offers the advantage that no for the transmitting and / or receiving device own place, in particular not in the vehicle interior, is needed and that parts of lighting devices for the transmitting and / or receiving device are utilized, namely always stable lamp glass of the lighting device, preferably by a cleaning means also can be kept clean during the journey. Known Cleaning devices operate it with wipers or with water jets at a higher pressure. Possibly can also include other components of the illumination device, in particular to emit signal beams shared be such as the reflector Illuminator.

0009The transmitting and / or receiving device can have its own optical system for forming have the special signal beam. In this case, the transmitting and / or receiving device in the lamp space, regularly through its own hole of the reflector adjacent to the bulb implementing, brought in. The lighting device can otherwise then remain unchanged. Alternatively or additionally, it is also possible to use additional beam-forming elements, preferably in the lamp glass lens for shaping the special Signal beam to realize. The lens takes expediently only a small portion of the surface of the luminaire case a to the radiation of the light of the lighting device not noticeably disturbing. However, is a precondition for this solution, that the beams influenced by glass lenses in shape are that so optical beam or the optical beam similar electromagnetic radiation from the transmitting and / or be sent or received receiver.

0010Under the same conditions, also the reflector Lighting device for housing the transmitting and / or be receiving machine exploited. This is due to a special Additional shaping of the reflector in the area of ​​the transmitting and / or Receiving device possible, but preferably also characterized be realized in that the emitted signal beam by a in the air space provided reflection means at least is partially directed to the reflector in the lamp room, especially by reflecting means on the surface of the Luminaire case. The reflection device can with a beam forming be provided or ray scattering reflector surface and may be disposed on the optical axis of the lamp and small compared to be the area of ​​the lamp glass so that even by the Reflection means die'Abstrahlung normal light of Illuminator is not not markedly disturbed or.

0011Operates the transmitting and / or receiving device with optical beams, will naturally be influenced by the light of the illumination device can not be avoided. This is reduced by that the transmitting and / or receiving device for transmitting and / or receiving a signal beam with a narrow Frequency band is designed. In addition, a carrier frequency be modulated with the optical signals, whereby the influence is minimized by the light from the illumination device.

0012The invention will in the following with reference to illustrated in the drawings Embodiments are explained in detail. Show it:<dl tsize="9"><dt>Figure 1 -</dt><dd>a section through a lighting device with an inserted transmitting and / or receiving device</dd><dt>Figure 2 -</dt><dd>a view according to Figure 1 with a modified lighting glass</dd><dt>Figure 3 -</dt><dd>a view according to Figure 1 with a with a Reflector surface provided lighting glass.</dd></dl>

0013Figure 1 can be a lighting device with a reflector 1, a light lens 2 and inserted into the reflector 1 Lamp 3 recognize. The reflector 1 is formed so that the schematically indicated with two beams emitted light from the lamp 3 passes as a searchlight beam through the glass shade 2 and for example, at the front of the car for lighting the road for the driver is used. The lamp glass 2 can be shaped so that the emitted headlamp beam in a desired manner is affected.

0014Closely adjacent to the lamp 3 is in the reflector 1 is a transmitting and / or Receiver 4 used whose emission or reception direction directed for a signal beam A by the lit glass 2 is parallel and in the illustrated embodiment to optical axis of the illumination device runs. An optical 5 of transmitting and / or receiving device 4 ensures that the beam A with a desired divergence, for example, as parallelized Beam is emitted or that the received beam A on focuses an optical sensor in the transmitting and / or receiving device becomes.

0015In the embodiment shown in Figure 2 is the glass shade 2 at the point at which the signal beam through the lamp glass 2 enters, is formed into a lens 6, the effect of the Optics 5 of the transmitting and / or receiving device 4 added. One of the Transmitting and / or receiving device 4 emitted divergent beam A can through the lens 6 to a beam C with a different divergence be transferred.

0016In the embodiment shown in Figure 3 is the Transmitting and / or receiving device 4 here so obliquely set that be emitted beam A at a reflection means 7, is arranged approximately in the optical axis of the lamp 3 is reflected becomes. For this purpose, the reflection means 7 with a reflecting surface provided that a change in the propagation direction caused and the beam shaping is used. In the illustrated Embodiment, the emitted beam A case by dispersive formation of reflection means 7 in a Cone beam widened B, of the reflector 1 to a wide parallel beam C is reflected by the lit glass 2 exits. Similarly, an entering beam C is the reflector 1 and the reflection means 7 on the optics 5 of transmitting and / or receiving device mapped.

0017The arranged in the optical axis reflection means 7 does not interfere with the emission of the lamp 3, since in most cases a direct emission of the lamp 3, ie without prior Reflection on the reflector 1, not desired and therefore often blocked the lying in the optical axis region becomes.

0018The illustrated embodiments show that by the inventive arrangement of the transmitting and / or receiving device 4 in the area defined by the reflector 1 and the lamp glass 2 Air space allows for space and cost-saving arrangement, a multiple utilization of the illumination device in Included parts allows.
