Abstract

Lamp assemblies for illuminating interior or exterior spaces of a vehicle are provided. In one implementation, a lamp assembly includes a housing having a frame, the housing being adapted to at least partially cover a light device installed within the housing. Light radiating from the light device passes through an opening in the frame. The lamp assembly further includes a lens adapted to be removably connected to the frame of the housing. When connected to the housing, the lens is adapted to refract the light radiating from the light device through the opening in the frame. When the lens is connected to the frame of the housing, a shortest path between the light device and the lens is defined by a z-axis. The lens may include one or more slide components to allow the lens to slide into or onto the frame along an x-axis that is perpendicular to the z-axis.

First claim

What is claimed is:

1. A lamp assembly for use in a vehicle, the lamp assembly comprising:
a housing having a frame, the housing adapted to at least partially enclose a light device installed within the housing, whereby light radiating from the light device passes through an opening in the frame; and
a lens adapted to be removably connected to the frame of the housing, such that, when connected to the housing, the lens is adapted to refract the light radiating from the light device through the opening in the frame, whereby, when the lens is connected to the frame of the housing, a shortest path between the light device and the lens is defined by a z-axis, the lens including one or more slide components adapted to allow the lens to slide into or onto the frame along an x-axis that is perpendicular to the z-axis;
wherein the housing includes a lid adapted to be disposed about at least a portion of the frame and the one or more slide components and adjacent to a surface of the lens facing an interior of the housing and prevent the lens from moving along the x-axis when the lens is connected to the frame.

2. The lamp assembly of claim 1 , wherein the one or more slide components extend from the surface of the lens facing an interior of the housing when the lens is connected to the frame of the housing.

3. The lamp assembly of claim 1 , wherein the frame of the housing includes one or more rails adapted to allow the one or more slide components of the lens to slide into or onto the frame along the x-axis.

4. The lamp assembly of claim 3 , wherein the one or more rails and the one or more slide components are adapted to prevent the lens from moving in a direction along the z-axis or along a y-axis that is perpendicular to both the x-axis and z-axis.

5. The lamp assembly of claim 3 , wherein the frame of the housing includes two rails and the lens includes two slide components.

6. The lamp assembly of claim 3 , wherein each of the one or more slide components comprises a riser and a ledge adapted to engage with one of the one or more rails of the frame.

7. The lamp assembly of claim 1 , wherein the housing further includes a base and a living hinge, and wherein the lid is adapted to pivot about the living hinge to enable the lid to cover at least a top portion and one or more side walls of the base.

8. The lamp assembly of claim 7 , wherein the base includes an abutment wall adapted to limit an extent to which the lens can slide onto the frame.

9. The lamp assembly of claim 7 , wherein the lid includes a locking strip and the base includes a locking edge, and wherein the locking strip is adapted to engage with the locking edge when the lid covers the top portion and one or more side walls of the base.

10. The lamp assembly of claim 7 , further comprising a printed circuit board adapted to support the light device, wherein the base is adapted to support the printed circuit board in such a way that the light radiating from the light device passes through the opening in the frame and through the lens.

11. The lamp assembly of claim 10 , wherein the printed circuit board is further adapted to support one or more electrical leads.

12. The lamp assembly of claim 11 , wherein the housing further includes a connector adapted for connection with an electrical plug for providing power to the light device, and wherein the connector is adapted to shield the one or more electrical leads.

13. A lens adapted for connection to a housing of a lamp assembly for use in a vehicle, the lens comprising:
a refraction element adapted for refracting light radiating from a light device installed in the housing of the lamp assembly, the refraction element oriented within a plane defined by an x-axis and a y-axis, whereby a shortest path between the light device and the plane is defined by a z-axis perpendicular to the x-axis and the y-axis; and
one or more connection elements extending from an interior portion away from edges of a first surface of the refraction element facing an interior of the housing and adapted to enable the lens to be removably connected to the housing of the lamp assembly by moving the lens in a connecting direction substantially within or parallel to the plane defined by the x-axis and y-axis.

14. The lens of claim 13 , wherein the one or more connection elements include first and second slide components adapted to enable the lens to slide into engagement with one or more corresponding rails of the housing of the lamp assembly.

15. The lens of claim 14 , wherein the first and second slide components are arranged in a direction parallel to the plane.

16. The lens of claim 13 , wherein, when the lens is connected to the housing, movement of the lens in the connecting direction is limited by a lid of the housing.

17. The lens of claim 13 , wherein the one or more connection elements include one or more leading edges adapted to abut an abutment wall of the housing when the lens is connected to the housing of the lamp assembly.

18. The lamp assembly of claim 1 , wherein the lens has a width that is greater than a length of the one or more slide components and a width of the opening in the frame.

19. The lamp assembly of claim 1 , wherein the lens has a length that is greater than a length of the opening in the frame.

20. The lens of claim 13 , wherein the refraction element has a width that is greater than a length of the one or more connection elements and a width of the housing of the lamp assembly.
