Abstract

A vehicle light assembly with an outer lens having at least two regions to be illuminated and employing semiconductor light sources arranged into at least two lighting circuits, a different lighting circuit illuminating each region and the light sources in one lighting circuit being mounted on an opposite side of a planar mount in the light assembly from the light sources in the other lighting circuit. A reflector is provided in the assembly housing, either as a separate body or as an integrally formed surface, and includes a first array of reflecting surfaces inclined to direct light from the light sources in the first lighting circuit through a first region of the outer lens and a second array of reflecting surfaces inclined to direct light from the light sources in the second lighting circuit through a second region of the outer lens. Light sources whose emitted light is absorbed by the outer lens to a larger degree than other light sources in the assembly can have an array of collimating lenses placed in the light path to improve their efficiency.

Claims

1. A vehicular light assembly comprising:

a housing for attachment to a vehicle;

an outer lens having at least first and second regions to be illuminated;

a generally planar mount having semiconductor light sources mounted on first and second opposed sides to form at least a first lighting circuit on the first opposed side and at least a second lighting circuit on the second opposed side, the planar mount being mounted in the housing behind the outer lens; and

a reflector in said housing configured to direct light from the light sources in the first lighting circuit through the first region of the outer lens and further configured to direct light from the light sources in the second lighting circuit through the second region of the outer lens.

2. The vehicular light assembly of claim 1, wherein said reflector comprises a first array of reflecting surfaces inclined to the planar mount and a second array of reflecting surface inclined to the planar mount.

3. The vehicular light assembly of claim 2, further comprising an array of collimating lenses spaced correspondingly to a plurality of the light sources in the second lighting circuit and being disposed between the light sources and the second array of reflecting surfaces to focus the light from the second circuit light sources onto the second region of the lens.

4. The vehicular light assembly of claim 3 wherein the light sources of the first lighting circuit emit a narrow band of light of a first wavelength and the light sources of the second lighting circuit emit a narrow band of light of a second wavelength different than the first wavelength, the outer lens being relatively transmissive to light of the second wavelength, sustaining said second wavelength.

5. The vehicular light assembly of claim 4 wherein the first wavelength corresponds to the color red and the second wavelength corresponds to the color amber and the color of the outer lens is red.

6. The vehicular light assembly of claim 5 wherein the reflector is integrally formed within said housing and has a reflective coating applied to it.

7. The vehicular light assembly of claim 1 wherein the light sources of the first lighting circuit emits red light and the light sources of the second lighting circuit emits amber light and the color of the outer lens is red.

8. The vehicular light assembly of claim 7 further comprising a collimating lens positioned to collimate said amber light.

9. The vehicular light assembly of claim 8 wherein said collimating lens is positioned between the second lighting circuit and the reflector.

10. The vehicle light assembly of claim 7 further comprising an array of collimating lenses positioned to collimate light from each of the light sources of the second lighting circuit.

11. The vehicle light assembly of claim 10 wherein said array of collimating lenses are positioned between the second lighting circuit and the reflector.

12. The vehicle light assembly of claim 11 wherein said array of collimating lenses are integrally formed.

13. The vehicle light assembly of claim 1 further comprising a bezel positioned between the outer lens and the planar mount occluding at least said first lighting circuit.

14. The vehicle light assembly of claim 13, further comprising an array of collimating lenses mounted on said planar mount collimating light from each of the light sources of said second lighting circuit.

15. A vehicle light assembly comprising:

a housing;

an outer lens mounted to said housing and having at least two regions to be illuminated;

a relatively planar member having first and second opposed sides mounted in said housing;

a plurality of semiconductor light sources being arranged into two lighting circuits; and

a reflector in the housing, said reflector reflecting light from said light sources towards said outer lens, characterized by one lighting circuit to illuminate each region of the outer lens and the light sources in one lighting circuit being mounted on the first opposed side of the planar member and the light sources in the second lighting circuit being mounted on the second opposed side of the planar member.

16. The vehicle light assembly of claim 15, wherein said reflector comprises a first array of reflecting surfaces inclined to the planar member reflecting light from the first lighting surfaces to a first region of the outer lens and a second array of reflecting surfaces inclined to the planar member reflecting light from the second lighting surfaces to the second region of the outer lens.

17. The vehicular light assembly of claim 16, further comprising an array of collimating lenses mounted on said planar member collimating light from each of the light sources of said second lighting circuit and directing said collimated light towards said array of reflecting surfaces.

18. The vehicle light assembly of claim 17 further comprising a bezel positioned between the outer lens and the planar member occluding a direct view ofat least said first lighting circuit.

19. The vehicle light assembly of claim 18 wherein said collimating lenses are integrally formed.

20. The vehicular light assembly of claim 19 wherein the light sources of the first lighting circuit emits a narrow band of red light and the second lighting circuit emits a narrow band of amber light and the color of the outer lens is red.
