Abstract

The present invention provides various lamp assembly configurations for motorized vehicles. In one embodiment, the lamp assembly includes a light source, such as a light emitting diode (LED) module, that is operable to generate light. The light source is attached to the vehicle structure, located on the interior of the vehicle adjacent to the aperture. A light guide is operatively connected to the light source. The light guide is configured to transmit light generated by the light source to preselected locations along the exterior of the vehicle structure, and diffuse the light. The light guide is attached to the vehicle structure, located on the exterior of the vehicle adjacent to the aperture in opposing relation to the light source. The cross-sectional area of the aperture formed through the vehicle structure is less than the cross-sectional areas of the LED module body and the light emitting segment of the light guide.

Claims (30)

1. A lamp assembly for a vehicle having vehicle structure defining an aperture therethrough, the lamp assembly comprising:

a light source member operable to generate light and configured to attach to the vehicle structure, wherein said light source member is disposed on an interior of the vehicle structure adjacent to the aperture; and

a light guide member operatively connected to said light source member and configured to transmit light generated by the light source member to preselected locations along the exterior of the vehicle structure, wherein said light guide member is disposed on an exterior of the vehicle structure adjacent to the aperture in opposing relation to said light source member.

2. The lamp assembly of claim 1 , wherein said light source member is a light emitting diode (LED) module.

3. The lamp assembly of claim 2 , wherein said LED module includes a body portion with an interface portion projecting outward therefrom, said interface portion configured to operatively mate with said light guide member.

4. The lamp assembly of claim 3 , wherein a cross-sectional area of the aperture is less than a cross-sectional area of said LED module body.

5. The lamp assembly of claim 1 , wherein said light guide member includes an interface segment protruding from a light emitting segment, said interface segment configured to operatively mate with said light source member, and said light emitting segment configured to diffuse light generated by the light source member.

6. The lamp assembly of claim 5 , wherein a cross-sectional area of the aperture is less than a cross-sectional area of said light emitting segment.

7. The lamp assembly of claim 1 , further comprising:

a generally translucent lens member configured to cover said light guide member; and

a housing member configured to mate with and attach said lens member and said light source member to the vehicle structure.

8. The lamp assembly of claim 7 , wherein said housing member has a cup portion with a flange portion extending outward from one end thereof, said cup portion defining a slot configured to receive and lock said light source member to said housing member, and wherein said flange portion includes a lens-to-housing joint configured to receive and attach said lens member to said housing member.

9. The lamp assembly of claim 1 , characterized by the absence of a sheet metal pocket attached to the vehicle structure and configured to nest said light source therein.

10. The lamp assembly of claim 1 , characterized by the absence of an outer lens.

11. The lamp assembly of claim 1 , characterized by the absence of a housing that is configured to mate with and attach said light source member and said light guide member to the vehicle structure.

12. A rear brake light assembly for a motorized vehicle having rear vehicle structure with an aperture formed therethrough, the brake light assembly comprising:

a light emitting diode (LED) module having a module body with an interface portion projecting outward therefrom, said interface portion configured to fit within the aperture and having at least one LED mounted thereto, wherein said LED module body is disposed entirely on an interior of the vehicle structure; and

a light guide having an interface segment projecting from an elongated light emitting segment, said interface segment configured to operatively mate with said LED module, and said light emitting segment disposed entirely on an exterior of the vehicle structure and configured to transmit and diffuse light generated by the LED module at preselected locations along the exterior of the vehicle structure.

13. The brake light assembly of claim 12 , wherein said LED module body has a first cross-sectional area, said light emitting segment has a second cross-sectional area, and the aperture formed through the rear vehicle structure has a third cross-sectional area that is less than said first and second cross-sectional areas.

14. The brake light assembly of claim 12 , further comprising:

a generally translucent rigid outer lens configured to receive and encase said light emitting segment therein; and

a light housing configured to mate with and attach said outer lens and said LED module to the rear vehicle structure.

15. The brake light assembly of claim 14 , wherein said housing has a generally cylindrical cup portion with a flange portion extending radially outward from one end thereof, said cup portion defining a slot configured to receive and lock said LED module to said housing, and wherein said flange portion includes a lens-to-housing joint configured to receive and attach said lens to said housing.

16. The brake light assembly of claim 12 , characterized by the absence of a sheet metal pocket attached to the vehicle structure and configured to nest said light source therein.

17. The brake light assembly of claim 12 , characterized by the absence of an outer lens configured to cover said light guide member.

18. The brake light assembly of claim 16 , characterized by the absence of a housing that is configured to mate with and attach said LED module and said light guide member to the vehicle structure.

19. A motorized vehicle, comprising:

a vehicle body having a front end opposing a rear end with at least one body panel positively attached thereto to define an internal compartment, said at least one body panel defining a receiving hole therethrough;

a light emitting diode (LED) module having a module body with an interface portion projecting outward therefrom, said interface portion extending into said receiving hole and having at least one LED mounted thereto, wherein said module body is disposed entirely within said internal compartment; and

a light guide having an interface segment projecting from an elongated light emitting segment, said interface segment abutting against said LED module interface portion, wherein said light emitting segment is disposed entirely on an exterior of the vehicle body panel and configured to transmit and diffuse light generated by the LED module at preselected locations along the exterior of the vehicle body.
