Abstract

A light emitting diode (LED) warning signal light and communication device comprising a controller for generating a first observable light signal and a second non-observable light signal within said first light signal. The second light signal is formed of packets of individual pulsed light which may be processed for comparison to data stored in memory integral to a controller for communication of information to an individual through the use of pulsed light signals.

Claims

1. A light signal comprising:

a) a light support having a plurality of light emitting diodes attached thereto, said light emitting diodes receiving power from a power source; and

b) a controller in communication with said light emitting diodes, said controller being constructed and arranged to illuminate said light emitting diodes to simultaneously create at least one first light signal, and at least one second light signal, said first light signal being observable to the unaided eyes of an individual and said second light signal not being observable to the unaided eyes of said individual.

2. The light signal according to claim 1 further comprising a storage device having a plurality of second light signals, said controller being in communication with said storage device for generation of said second light signals.

3. The light signal according to claim 1 wherein said light support is engaged to a building.

4. The light signal according to claim 1 wherein said light support is engaged to a street light.

5. The light signal according to claim 1 wherein said light support is engaged to a traffic control device.

6. The light signal according to claim 5, said traffic control device comprising a semaphore.

7. The light signal according to claim 1 wherein said light support is engaged to a sign.

8. The light signal according to claim 1 wherein said light support is engaged to a vehicle.

9. The light signal according to claim 8, said vehicle comprising a bus.

10. The light signal according to claim 8, said vehicle comprising an automobile.

11. The light signal according to claim 8, said vehicle comprising a train.

12. The light signal according to claim 8, said vehicle comprising a subway car.

13. The light signal according to claim 8, said vehicle comprising a truck.

14. The light signal according to claim 1, said second light signal comprising rapid light pulses.

15. The light signal according to claim 14, wherein said rapid light pulses are grouped into at least one packet.

16. The light signal according to claim 15, wherein said at least one packet is formed into at least one combination of packets.

17. The light signal according to claim 14, said light signal further comprising a photo detector engaged to said support, said photo detector being in communication with said controller.

18. The light signal according to claim 17, wherein said photo detector is constructed and arranged to detect said rapid light pulses.

19. The light signal according to claim 1, wherein said controller illuminates at least two of said first light signals in at least one combination.

20. The light signal according to claim 1, wherein said controller illuminates at least two of said first light signals simultaneously.

21. The light signal according to claim 1, wherein said light signal is engaged to a structure.

22. The light signal according to claim 1, wherein said light signal is engaged to a tower.

23. The light signal according to claim 1, wherein said light signal is engaged to a light post.
