Abstract

A modular warning signal light system comprising at least one support. The at least one support having at least one module receiving port. The module receiving ports constructed and arranged to removably receive the support engagement member of a module. Each module having at least one visible side. The at least one visible side having at least one light emitting diode light source engaged thereto. The at least one light emitting diode light source, module and support all in independent electrical communication with a controller. The controller constructed and arranged to selectively activate the at least one support, the at least one module, the at least one light emitting diode light source, and any combinations thereof to create at least one warning light signal.

Claims

1. A modular warning signal light system comprising:

at least one support, the at least one support having at least one module receiving port;

at least one module, the at least one module having at least one visible side, the at least one visible side having at least one light emitting diode light source engaged thereto, the at least one module having at least one support engagement member, the at least one support engagement member constructed and arranged to be removably received by the at least one module receiving port, the at least one module and the at least one light emitting diode light source in electric communication with one another and with the at least one support; and

a controller, the controller in electric communication with the at least one support, the at least one module and the at least one light emitting diode light source, the controller constructed and arranged to selectively activate the at least one light emitting diode light source to create at least two warning light signals, the controller constructed and arranged to provide the at least two warning light signals simultaneously, said light emitting diodes receiving power from a power source.

2. The system of claim 1 wherein the controller is adapted to vary the illumination intensity provided to the selectively activated at least one light emitting diode light source.

3. The system of claim 2 wherein the at least one light emitting diode light source is a plurality of light emitting diodes.

4. The system of claim 2 wherein the at least one receiving port is a plurality of receiving ports.

5. The system of claim 4 wherein at least one module is a plurality of modules.

6. The system of claim 5 wherein the controller selectively activates the at least one light emitting diode light source on the at least one visible side of a plurality of modules to thereby produce a plurality of warning light signals.

7. The system of claim 6 wherein the controller is in independent electrical communication with each of the light emitting diode light sources.

8. The system of claim 7 wherein the plurality of light emitting diode light sources are independently and selectively activated thereby producing at least one warning light signal to be displayed from each of the visible surfaces.

9. The system of claim 8 wherein the plurality of light emitting diode light sources on each of the modules are selectively activated thereby providing each of the plurality of modules with at least one warning light signal.

10. The system of claim 9 wherein at least two modules display warning light signals which are different from one another.

11. A modular warning signal light system comprising:

at least one support, the at least one support having at least one modular receiving port;

at least one module, the at least one module having at least one visible side, the at least one visible side having at least one light emitting diode light source engaged thereto, the at least one module having at least one support engagement member, the at least one support engagement member constructed and arranged to be removably received by the at least one modular receiving port, the at least one module and the at least one light emitting diode light source in electric communication with one another and with the at least one support; and

a controller, the controller in electric communication with the at least one support, the at least one module and the at least one light emitting diode light source, the controller constructed and arranged to selectively activate the at least one light emitting diode light source to create at least two warning light signals, the controller constructed and arranged to produce the at least two warning light signals in at least one combination, said light emitting diode light sources receiving power from a power source.

12. The system of claim 11 wherein the controller is adapted to vary the illumination intensity provided to the selectively activated at least one light emitting diode light source.

13. The system of claim 12 wherein the at least one light emitting diode light source is a plurality of light emitting diodes.

14. The system of claim 12 wherein the at least one receiving port is a plurality of receiving ports.

15. The system of claim 14 wherein at least one module is a plurality of modules.

16. The system of claim 15 wherein the controller selectively activates the at least one light emitting diode light source on the at least one visible side of the plurality of modules to thereby produce a plurality of warning light signals.

17. The system of claim 16 wherein the controller is in independent electric communication with each of the light emitting diode light sources.

18. The system of claim 17 wherein the plurality of light emitting diode light sources are independently and selectively activated thereby producing at least one warning light signal to be displayed from each of the visible surfaces.

19. The system of claim 18 wherein the plurality of light emitting diode light sources on each of the modules are selectively activated thereby producing each of the plurality of modules with at least one warning light signal.

20. The system of claim 19 wherein the at least two modules display warning light signals which are different from one another.
