Abstract

A compact lamp assembly for use in interior vehicle application such as reading and courtesy lighting. The lamp assembly includes a housing, a circuit board, and an LED. The housing has a front wall with a concave portion and annular bezel, as well as a side wall and several interior walls. The concave surface includes an off-center opening that is aligned along an axis that forms an oblique angle with respect to the central axis of the housing. The LED is mounted to the circuit board and is positioned in a protective interior space formed behind the opening in the concave surface. When assembled, the LED emits light through the opening such that it exits the lamp assembly at an angle, traveling along the axis of the opening rather than along the central axis of the housing.

Claims

1. A lamp assembly for use with a vehicle component, comprising:

a housing having a front wall and at least one side wall that extends away from said front wall, said front wall including a generally concave surface with an opening for allowing light transmission, said concave surface being generally aligned along a first axis and said opening being generally aligned along a second axis that is oblique with respect to said first axis;

a circuit board mounted to said housing; and

a light emitting diode (LED) electrically coupled to said circuit board, wherein said LED is aligned to provide illumination through said opening and generally along said second axis.

2. The lamp assembly of claim 1, wherein said front wall further includes an annular bezel generally surrounding said concave surface.

3. The lamp assembly of claim 2, wherein said annular bezel extends beyond said side wall to form a flange having a rear surface that contacts a front surface of the vehicle component when said lamp assembly is installed.

4. The lamp assembly of claim 1, wherein said housing further includes at least one interior wall connected to said concave surface to form an interior space behind said opening.

5. The lamp assembly of claim 4, wherein said LED is mounted to said circuit board and wherein said circuit board is press-fit generally within said interior space so that said LED can provide illumination through said opening.

6. The lamp assembly of claim 1, wherein said assembly further includes an electrical connector coupled to said circuit board to provide said assembly with a detachable electrical connection.

7. The lamp assembly of claim 1, wherein said side wall includes at least one mounting clip located on its outer surface to aid in installation of said assembly to the vehicle component.

8. The lamp assembly of claim 1, wherein said assembly further includes a lens disposed in said opening.

9. A lamp assembly for use with a vehicle component, comprising:

a housing having a front wall, a generally cylindrical side wall extending from said front wall, and at least one interior wall;

said front wall including a concave portion with an opening for allowing light transmission and an annular bezel that surrounds said concave portion;

said at least one interior wall being in contact with said concave portion and at least partially forming an interior space located behind said opening;

a circuit board located generally within said housing; and

an LED electrically coupled to said circuit board and located generally within said interior space so that said LED can provide illumination through said opening.

10. The lamp assembly of claim 9, wherein said concave portion and said annular bezel are generally disposed coaxially along a first axis, and wherein light from said LED exits said lamp assembly generally along a second axis that is oblique relative to said first axis.

11. The lamp assembly of claim 10, wherein said opening is offset from said first axis.

12. The lamp assembly of claim 9, wherein said annular bezel extends beyond said side wall to form a flange having a rear surface that contacts a front surface of the vehicle component when said lamp assembly is mounted within an opening in said vehicle component.

13. The lamp assembly of claim 9, wherein said LED is mounted to said circuit board and wherein said circuit board is press-fit generally within said interior space so that said LED can provide illumination through said opening.

14. The lamp assembly of claim 9, wherein said assembly further includes an electrical connector coupled to said circuit board to provide said assembly with a detachable electrical connection.

15. The lamp assembly of claim 9, wherein said side wall includes at least one mounting clip located on its outer surface to aid in installation of said assembly to the vehicle component.

16. The lamp assembly of claim 10, wherein said assembly further includes a lens disposed in said opening.

17. A lamp assembly for mounting in an opening in a substantially planar portion of a vehicle interior panel, comprising:

a light source; and

a housing having a front cover that includes an outer bezel having a rear surface that defines a mounting plane such that said rear surface abuts the substantially planar portion of the vehicle interior panel when said housing is inserted into the opening from a front side of the panel, said front cover having a concave portion surrounded by said bezel and extending inwardly of said rear surface into the opening when said housing is inserted into the opening with said rear surface abutting the panel, said concave portion having a window with said light source being mounted in said housing behind said window such that light from said light source exits said lamp assembly at an angle that is oblique relative to said mounting plane.

18. The lamp assembly of claim 17, wherein said bezel comprises an annular bezel having an outer flange that includes said rear surface, and wherein said concave portion extends inwardly from said annular bezel.

19. The lamp assembly of claim 17, wherein said concave portion is centered on an axis that extends normal to said mounting plane, and wherein said window is offset from said axis such that light from said light source exits said window along a second axis that is angled relative to said first axis.

20. The lamp assembly of claim 17, further comprising a circuit board located within said housing behind said concave portion, wherein said light source comprises an LED mounted to said circuit board behind said window.
