Abstract

A lamp for the rear of a vehicle is disclosed with a light transmissive cover having a red first illuminated surface area and a clear second illuminated surface area. It has a first LED light emitter located directly beneath the red first area, a second LED light emitter located directly beneath the clear second area, and a third LED light emitter, also located directly beneath said clear second area. The third red LED light emitter is for emitting red light through the clear second area simultaneously with light transmitted through the red first area, whereby the first and second areas are adapted to collectively form a contiguous red illuminated surface area.

Claims

1. A lamp for the rear of a vehicle, including:

a light transmissive cover having a first illuminated surface area and a second illuminated surface area;

(a) said first area of said cover being light transmissive and being red in color;

(1) a first LED light emitter located directly beneath said first area;

(b) said second area being light transmissive and being clear in color;

(2) a second light emitter located directly beneath said clear second area and, wherein said second light emitter comprises an LED that emits white light;

(3) a third light emitter located directly beneath said clear second area, said third light emitter emitting comprises a red LED for emitting red light through said clear second area simultaneously with light transmitted through said red first area, whereby said first and second areas are adapted to collectively form a contiguous red illuminated surface area.

2. The lamp of claim 1 wherein the lamp is a stop-tail-turn lamp for a vehicle and wherein the sum of said first illuminated surface area and said second illuminated surface area is at least 50 square centimeters and is less than 100 square centimeters.

3. The lamp of claim 2 wherein said white second light emitter is activated upon the vehicle being placed in reverse.

4. The lamp of claim 3 wherein said red first light emitter and said red third light emitter are each activated upon the vehicle head lamps being activated.

5. The lamp of claim 4 wherein said red first light emitter and said red third light emitter each emit brighter light upon the vehicle braking.

6. The lamp of claim 5 wherein the lamp is a stop-tail-turn lamp for a vehicle and wherein the sum of said first illuminated surface area and said second illuminated surface area is at least 75 square centimeters and is less than 100 square centimeters.

7. The lamp of claim 6 wherein said lamp comprises a fourth light emitter located directly beneath said clear second area and, wherein said fourth light emitter comprises an LED that emits amber light.

8. The lamp of claim 7 wherein said lamp is shaped from a group consisting of:

(a) a circle with a diameter of about 10 centimeters; and

, (b) an oval.

9. The lamp of claim 1 wherein said white second light emitter is activated upon the vehicle being placed in reverse.

10. The lamp of claim 1 wherein said red first light emitter and said red third light emitter are each activated upon the vehicle head lamps being activated.

11. The lamp of claim 10 wherein said red first light emitter and said red third light emitter each emit brighter light upon the vehicle braking.

12. The lamp of claim 1 wherein the lamp is a stop-tail-turn lamp for a vehicle and wherein the sum of said first illuminated surface area and said second illuminated surface area is at least 75 square centimeters and is less than 100 square centimeters.

13. The lamp of claim 9 wherein the lamp is a stop-tail-turn lamp for a vehicle and wherein the sum of said first illuminated surface area and said second illuminated surface area is at least 50 square centimeters and is less than 100 square centimeters.

14. The lamp of claim 9 wherein the lamp is a stop-tail-turn lamp for a vehicle and wherein the sum of said first illuminated surface area and said second illuminated surface area is at least 75 square centimeters and is less than 100 square centimeters.

15. The lamp of claim 9 wherein said lamp comprises a fourth light emitter located directly beneath said clear second area and, wherein said fourth light emitter comprises an LED that emits amber light.

16. The lamp of claim 1 wherein said lamp comprises a fourth light emitter located directly beneath said clear second area and, wherein said fourth light emitter comprises an LED that emits amber light.

17. The lamp of claim 1 wherein said lamp is shaped as a circle with a diameter of about 10 centimeters.

18. The lamp of claim 1 wherein said lamp is shaped as an oval.

19. The lamp of claim 1 wherein said lamp is a single compartment lamp.

20. The lamp of claim 1 wherein said lamp is a multiple compartment lamp.

21. The lamp of claim 1 wherein there is no parabolic reflector and no barrier wall between said first LED light emitter and said third LED light emitter.

22. A lamp for the rear of a vehicle, including:

a light transmissive cover having a first illuminated surface area and a second illuminated surface area;

(a) said first area of said cover being light transmissive and being red in color;

(1) a first LED light emitter located directly beneath said first area;

(b) said second area being light transmissive and being clear in color;

(2) a second light emitter located directly beneath said clear second area and, wherein said second light emitter comprises an LED for emitting amber light;

(3) a third light emitter located directly beneath said clear second area, said third light emitter emitting comprises a red LED that emits red light through said clear second area simultaneously with light transmitted through said red first area, whereby said first and second areas are adapted to collectively form a contiguous red illuminated surface area.

23. The lamp of claim 22 wherein said amber second light emitter is activated upon the activation of a turn indicator.

24. The lamp of claim 23 wherein said lamp is a single compartment lamp.

25. The lamp of claim 23 wherein said lamp is a multiple compartment lamp.

26. The lamp of claim 23 wherein there is no parabolic reflector and no barrier wall between said first LED light emitter and said third LED light emitter.
