Abstract

A vehicle lamp that includes an integrated sensor for interacting with an operating environment of a vehicle is provided. The vehicle lamp includes a sensor and a light channel adapted to transmit data received by the sensor. The vehicle lamp can also include a flat wire that has a component integrally formed by the light channel. A vehicle illumination and data transmission system is also provided. The system includes vehicle lamps according to the present invention, and can include sensor processors located within each of a plurality of lamps, or sensor processors that are centrally located within the vehicle. A system processor is connected to the sensor processors and enables operating decisions based upon data received from the environment by the sensors.

Claims

1. A vehicle lamp for illuminating an environment external to the vehicle and for relaying data between the vehicle and the environment, the vehicle lamp comprising:

a housing defining an interior chamber;

a bulb disposed within said interior chamber and adapted to emit light;

a reflective surface disposed within said interior chamber and adapted to bundle said light and direct said light out of said interior chamber;

a bulb shield disposed adjacent said bulb and adapted to substantially prevent said light from exiting said interior chamber without encountering said reflective surface;

a sensor disposed within said interior chamber and adapted to receive the data from the external environment, the sensor positioned adjacent the bulb shield; and

a light channel operably connected to said sensor and adapted to transmit the data away from said sensor.

2. The vehicle lamp of claim 1, wherein said bulb shield is positioned between said sensor and said bulb.

3. The vehicle lamp of claim 1, wherein said sensor is a member selected from the group consisting of radar sensors, radio frequency sensors, infrared sensors, ultrasonic sensors, and laser-based radar sensors.

4. The vehicle lamp of claim 1, further comprising a processor adapted to convert the date received by said sensor from the external environment into a light waveform suitable for transmission along said light channel.

5. The vehicle lamp of claim 1, wherein said sensor is further adapted to transmit the data to the external environment;

and

further comprising a processor adapted to convert the data from a light waveform suitable for transmission along said light channel into a different form suitable for transmission to the external environment by said sensor.

6. The vehicle lamp of claim 1, further comprising a wire operably connected to said sensor and a power supply;

wherein said wire is adapted to transmit electrical power from said power supply to said sensor.

7. The vehicle lamp of claim 6, wherein said wire is a flat wire.

8. The vehicle lamp of claim 7, wherein said flat wire includes a conductive portion and a non-conductive portion;

and

wherein said non-conductive portion is integrally formed by said light channel.

16. The vehicle lamp of claim 1, wherein the bulb shield is structured to re-direct light from the bulb to the reflective surface.

17. The vehicle lamp of claim 16, wherein the bulb shield has a reflective interior surface.

9. A vehicle illumination and data transmission system, comprising:

a plurality of vehicle lamps, each vehicle lamp of said plurality comprising a housing, a bulb disposed within said housing, and adapted to emit light, a reflective surface adapted to bundle said light, a bulb shield disposed adjacent said bulb, a sensor disposed within said housing and adapted to receive data from an external environment, and a light channel operably connected to said sensor and adapted to transmit the received data away from said sensor;

a system processor adapted to process data from received by each sensor from said plurality of vehicle lamp; and

a plurality of sensor processors adapted to process data from the plurality of sensors of said plurality of vehicle lamps and transmit data to said system processor.

10. The vehicle illumination and data transmission system of claim 9, wherein each of said plurality of sensor processors is operably connected to one of said sensors of said plurality of vehicle lamps.

11. The vehicle illumination and data transmission system of claim 10, wherein each of said plurality of sensor processors is disposed within one of said housings of said plurality of vehicle lamps.

12. The vehicle illumination and data transmission system of claim 9, wherein said at least one sensor processor comprises a single sensor processor;

and

wherein each of said light channels of said plurality of vehicle lamps operably connects one of said sensor to said sensor processor.

13. The vehicle illumination and data transmission system of claim 9, wherein said at least one sensor processor comprises first end second sensor processors;

wherein said plurality of vehicle lamps comprises first and second groups of vehicle lamps;

wherein each of said light channels of said first group of vehicle lamps operably connects one of said sensors to said first sensor processor; and

wherein each of said light channels of said second group of vehicle lamps operably connects one of said sensors to said second sensor processor.

14. The vehicle illumination and data transmission system of claim 9, wherein each of said plurality of vehicle lamps comprises a wire operably connected to said sensor and a power supply;

wherein said wire is adapted to transmit electrical power from said power supply to said sensor;

wherein said wire includes a conductive portion and a non-conductive portion; and

wherein said non-conductive portion is integrally formed by said light channel.

15. A vehicle illumination and data transmission system, comprising:

a plurality of vehicle lamps, each lamp of said plurality comprising a housing, a bulb disposed within said housing and adapted to emit light, a reflective surface adapted to bundle said light, a bulb shield disposed adjacent said bulb, a sensor disposed within said housing and adapted to receive data from an external environment, a sensor processor adapted to process data received by said sensor, a light channel adapted to transmit the processed data away from said sensor, and a wire operably connected to said sensor and a power supply adapted to transmit electrical power from said power supply to said sensor, the wire including a conductive portion and a non-conductive portion, the non-conductive portion being integrally formed by said light channel; and

a system processor connected to each sensor of each of said plurality of vehicle lamp by said light channel, said system processor adapted to further process data transmitted away from said sensor by said light channel.
