Abstract

A headlamp assembly according to the invention includes an integrated night vision illuminator element, such as an infrared illuminator. The headlamp assembly also includes a low beam light bulb element and a high beam light bulb element. A lens attached to the front of the headlamp housing encloses the two light bulb elements and the infrared illuminator within the housing. The headlamp assembly is preferably an integrated module that can be installed quickly and easily into an automobile.

Claims

1. A headlamp assembly comprising:

a headlamp housing;

at least one visible light projector coupled to said headlamp housing;

at least one night vision illuminator coupled to said headlamp housing; and

a lens attached to said headlamp housing, said lens enclosing said at least one visible light projector and said at least one night vision illuminator within said headlamp housing, wherein at least a portion of said lens has optical characteristics that affect illumination beam pattern width and range of energy emitted by said at least one night vision illuminator.

2. A headlamp assembly according to claim 1, wherein said at least one night vision illuminator comprises at least one infrared illuminator.

3. A headlamp assembly according to claim 2, wherein said at least one infrared illuminator comprises at least one near-infrared illuminator.

4. A headlamp assembly according to claim 1, wherein said at least one visible light projector comprises at least one low beam element.

5. A headlamp assembly according to claim 1, wherein said at least one visible light projector comprises at least one high beam element.

6. A headlamp assembly according to claim 1, wherein said at least one night vision illuminator comprises at least one filtered incandescent light source.

7. A headlamp assembly according to claim 1, wherein said at least one night vision illuminator comprises at least one laser light source.

17. A headlamp assembly according to claim 1, wherein said headlamp housing is configured to accommodate alignment of said at least one visible light projector and alignment of said at least one night vision illuminator via adjustment of said headlamp housing itself.

8. A headlamp assembly comprising:

a headlamp housing;

a visible light projector integrated into said headlamp housing;

an infrared illuminator integrated into said headlamp housing; and

a lens attached to said headlamp housing, said lens enclosing said visible light projector and said infrared illuminator within said headlamp housing, wherein at least a portion of said lens has optical characteristics that affect illumination beam pattern width and range of energy emitted by said infrared illuminator.

9. A headlamp assembly according to claim 8, wherein said infrared illuminator comprises a near-infrared illuminator.

10. A headlamp assembly according to claim 8, wherein said visible light projector comprises a low beam element.

11. A headlamp assembly according to claim 8, wherein said visible light projector comprises a high beam element.

12. A headlamp assembly according to claim 8, wherein said infrared illuminator comprises a filtered incandescent light source.

13. A headlamp assembly according to claim 8, wherein said infrared illuminator comprises a laser light source.

18. A headlamp assembly according to claim 8, wherein said headlamp housing is configured to accommodate alignment of said visible light projector and alignment of said infrared illuminator via adjustment of said headlamp housing itself.

14. A headlamp assembly comprising:

a headlamp housing;

a first receptacle integrated into said headlamp housing, said first receptacle being configured to receive an infrared illuminator;

a second receptacle integrated into said headlamp housing, said second receptacle being configured to receive a visible light projector; and

a lens attached to said headlamp housing and enclosing said infrared illuminator and said visible light projector, a portion of said lens having optical characteristics that affect illumination beam pattern width and range of infrared energy emitted from a location proximate said first receptacle.

15. A headlamp assembly according to claim 14, wherein said visible light projector is a low beam projector.

16. A headlamp assembly according to claim 15, further comprising a third receptacle integrated into said headlamp housing, said third receptacle being configured to receive a high beam projector.

19. A headlamp assembly according to claim 14, wherein said headlamp housing is configured to accommodate alignment of said visible light projector and alignment of said infrared illuminator via adjustment of said headlamp housing itself.
