Abstract

A light emitting diode (LED) warning signal light, the warning signal light comprising a plurality of light sources constructed and arranged with a reflector or cullminator, the LED light source being in electrical communication with a controller and a power supply, battery, or other electrical source. The warning signal light provides various colored light signals for independent use or use by an emergency vehicle. These light signals may include a strobe light, revolving light, an alternating light, a flashing light, a modulated light, a pulsating light, an oscillating light or any combination thereof. Additionally, the warning signal light may be capable of displaying symbols, reverse characters, or arrows. The controller may further be adapted to regulate or modulate the power intensity exposed to the illuminated LED'"'"'s to create a variable intensity light signal.

Claims

1. An LED lighting device comprising:

a) an elongate frame;

b) a plurality of light emitting diode light sources engaged to said frame, said light emitting diode light sources being arranged in at least one row, said light emitting diode light sources receiving power from a power source; and

c) a controller in communication with said light emitting diode light sources, the controller constructed and arranged to activate the light emitting diode light sources thereby producing at least two different timing patterns of visually distinct warning light signals, one of said timing patterns of visually distinct warning light signals comprising the repetitive illumination of one or more light emitting diodes over a first period of time to form a first collection of visually distinct warning light signals and one of said timing patterns of visually distinct warning light signals comprising the repetitive illumination of one or more light emitting diodes over a second period of time to form a second collection of visually distinct warning light signals, the first timing pattern and the second timing pattern being different from each other, the controller further constructed and arranged to illuminate the first timing pattern and the second timing pattern in at least one combination of timing patterns.

2. The lighting device according to claim 1, said LED lighting device further comprising a reflector proximate to said light emitting diode light sources.

3. The lighting device according to claim 2, said reflector comprising a pair of mirrors.

4. The lighting device according to claim 3, wherein said mirrors are constructed and arranged to reflect light emitted from said light emitting diode light sources outwardly from said frame at a desired angle.

5. The lighting device according to claim 1, wherein said frame has a first end and a second end.

6. The lighting device according to claim 5, wherein each of said first end and said second end have an affixation area.

7. The lighting device according to claim 6, said frame further comprising a receiving ledge constructed and arranged for engagement to a lens.

8. The lighting device according to claim 1, said reflector comprising a plurality of collimator cups, each of said collimator cups constructed and arranged for positioning proximate to one of said light emitting diode light sources.

9. The lighting device according to claim 8, wherein said collimator cups are formed into an array.

10. The lighting device according to claim 8, each of said collimator cups comprising an angularly offset interior surface.

11. The lighting device according to claim 1, wherein said controller independently controls each of said light emitting diode light sources.

12. The lighting device according to claim 11, wherein the warning light signal is a directional indicator.

13. The lighting device according to claim 1, wherein the lighting device is engaged to a utility vehicle.

14. The lighting device according to claim 1, wherein the lighting device is engaged to an emergency vehicle.

15. The lighting device according to claim 1, wherein the at least two different timing patterns are produced simultaneously.

16. The lighting device according to claim 1, wherein the at least two different timing patterns are produced independently of each other.

17. The lighting device according to claim 1, wherein said at least two different timing patterns are different in duration.
