Abstract

A vehicle lighting system is provided primarily for use with emergency response vehicles. The lighting system preferably includes a planar plate mounted to one of the horizontal surfaces of a vehicle. A luminescent planar sheet is constructed to provide illuminated alphanumeric characters affixed upon the planar plate so as to illuminate upwardly so as to be seen from the air. Preferably the luminescent planar sheet can selectively produce visible light, or infrared light, or both. The vehicle lighting system also includes a light bar affixed to the planar plate. The light bar is positioned to illuminate primarily horizontally so as to be seen by those on the ground. Preferably, the luminescent planar sheets are connected by wiring to the light bar so that luminescent planar sheet obtains power from the light bar.

Claims

1. A vehicular light bar and luminescent indicia assembly comprising:

a frame having a horizontal planar surface;

an emergency response vehicle light bar affixed to said frame, said light bar constructed and affixed to said frame so as to emit light horizontally;

one or more luminescent planar sheets, said one or more luminescent planar sheets affixed upon said frame'"'"'s horizontal planar surface and constructed to provide luminescent indicia in the form of one or more letters or numbers which face upwardly so as to emit light upwardly so as to be seen from above; and

a power source for providing power to said light bar and said one or more luminescent planar sheets.

2. The vehicular light bar and luminescent indicia assembly of claim 1 wherein said frame is substantially planar to form a planar plate having a substantially planar upper surface, said light bar and said one or more luminescent planar sheets engage and are affixed to said planar plate'"'"'s substantially planar upper surface.

3. The vehicular light bar and luminescent indicia assembly of claim 1 wherein said one or more luminescent planar sheets are electro-luminescent panels.

4. The vehicular light bar and luminescent indicia assembly of claim 2 wherein said one or more luminescent planar sheets are electro-luminescent panels.

5. The vehicular light bar and luminescent indicia assembly of claim 1 wherein said one or more luminescent planar sheets comprise one or more light pipes connected to light emitting diodes (LEDs).

6. The vehicular light bar and luminescent indicia assembly of claim 1 wherein the luminescent planar sheets can primarily produce light that is not visible to the human eye.

7. The vehicular light bar and luminescent indicia assembly of claim 1 wherein said vehicle has only one power source in the form of a battery which also provides power to the vehicle'"'"'s remaining electrical systems.

8. The vehicular light bar and luminescent indicia assembly of claim 1 wherein said letters or numbers have a length of at least 18 inches.

9. The vehicular light bar and luminescent indicia assembly of claim 1 wherein said letters or numbers have a length of 18 inches to 48 inches.

10. A vehicular light bar and luminescent indicia assembly comprising:

a vehicle having four or more wheels, the vehicle having at least one substantially horizontal planar surface in the form of a hood surface, cabin roof surface, or trunk surface;

a frame which engages and affixes directly to said vehicle'"'"'s horizontal planar surface, said frame having a horizontal planar surface;

an emergency response vehicle light bar affixed to said frame, said light bar constructed and affixed to said frame so as to emit light horizontally;

one or more luminescent planar sheets, said one or more luminescent planar sheets affixed upon said frame'"'"'s horizontal planar surface and constructed to provide luminescent indicia in the form of one or more letters or numbers which face upwardly so as to emit light upwardly so as to be seen from above; and

a power source for providing power to said light bar and said one or more luminescent planar sheets.

11. The vehicular light bar and luminescent indicia assembly of claim 10 wherein said one or more luminescent planar sheets are electro-luminescent panels.

12. The vehicular light bar and luminescent indicia assembly of claim 10 wherein said one or more luminescent planar sheets comprise one or more light pipes connected to light emitting diodes (LEDs).

13. The vehicular light bar and luminescent indicia assembly of claim 10 wherein the luminescent planar sheets can primarily produce light that is not visible to the human eye.

14. The vehicular light bar and luminescent indicia assembly of claim 10 wherein said letters or numbers have a length of at least 18 inches.

15. The vehicular light bar and luminescent indicia assembly of claim 10 wherein said letters or numbers have a length of 18 inches to 48 inches.
