Abstract

A vehicle includes a vehicle body that defines a cargo space. The cargo space includes a cargo floor. A trim member is disposed on the vehicle body within the cargo space. The trim member defines an opening. The housing is disposed within the opening. A light source is disposed on the housing. A first lens is disposed adjacent to the light source. The first lens defines a first optic. A second lens is spaced-apart from the first lens. The second lens defines a second optic. The light source is configured to emit light through the first lens and the second lens into the cargo space.

First claim

What is claimed is:

1. A vehicle, comprising:
a vehicle body defining a cargo space, wherein the cargo space includes a cargo floor;
a trim member disposed on the vehicle body within the cargo space, wherein the trim member defines an opening;
a housing disposed within the opening;
at least one light source disposed on the housing;
at least one first lens disposed adjacent to the at least one light source, wherein the at least one first lens defines at least one first optic; and
a second lens spaced-apart from the at least one first lens, wherein the second lens defines a second optic that includes a plurality of optic members, wherein the at least one light source is configured to emit light through the at least one first lens and the second lens into the cargo space, and wherein each optic member of the second optic includes a curved surface and a planar surface configured to direct emitted light from the at least one light source toward the cargo floor.

2. The vehicle of claim 1 , wherein the at least one first optic includes a central optic and a radial optic surrounding the central optic.

3. The vehicle of claim 2 , wherein the radial optic includes a plurality of radially extending ridges defining radially extending channels and a plurality of concentric ridges defining concentric grooves.

4. The vehicle of claim 1 , wherein the at least one first optic includes an aspherical portion aligned with the at least one light source.

5. The vehicle of claim 4 , wherein the at least one first optic includes a radial optic surrounding the aspherical portion, wherein the radial optic includes radially extending ridges and concentric ridges.

6. The vehicle of claim 1 , wherein the second optic is configured to direct emitted light toward the cargo floor, and wherein the second optic is configured to disperse the emitted light laterally.

7. The vehicle of claim 1 , wherein the second lens defines the second optic on a B-surface of the second lens.

8. A vehicle cargo lamp assembly, comprising:
a circuit board;
first and second light sources disposed on the circuit board and spaced-apart from one another;
a first inner lens disposed proximate the first light source, wherein the first inner lens defines a first inner optic and a second inner optic;
a second inner lens disposed proximate the second light source, wherein the second inner lens defines a first inner optic and a second inner optic; and
an outer lens disposed proximate the first and second inner lenses, wherein the outer lens defines an outer optic, wherein the outer lens defines the outer optic on discrete portions thereof that align with the first and second inner lenses, respectively.

9. The vehicle cargo lamp assembly of claim 8 , wherein each of the first inner optics is an aspherical portion disposed centrally in each of the first and second inner lenses, respectively.

10. The vehicle cargo lamp assembly of claim 9 , wherein each of the second inner optics defines a first plurality of ridges extending radially from the aspherical portions and a second plurality of ridges extending concentrically around the aspherical portions, respectively.

11. The vehicle cargo lamp assembly of claim 8 , further comprising:
a housing defining a first recess and a second recess, and wherein the first and second inner lenses are disposed within the first and second recesses, respectively.

12. The vehicle cargo lamp assembly of claim 8 , wherein each of the second inner optics defines a plurality of radially extending channels and a plurality of concentric grooves, wherein the plurality of concentric grooves intersect the plurality of radially extending channels.

13. A cargo lamp assembly, comprising:
a circuit board;
a light source disposed on the circuit board;
an inner lens disposed adjacent to the light source, wherein the inner lens defines a first inner optic and a second inner optic, and wherein the first inner optic is an aspherical portion and the second inner optic is a plurality of radially extending ridges and a plurality of concentric ridges; and
an outer lens disposed adjacent to the inner lens, wherein the outer lens defines an outer optic, and wherein the light source emits light through the inner lens and the outer lens when the light source is activated.

14. The cargo lamp assembly of claim 13 , wherein an apex of the aspherical portion is offset from a central axis of the light source.

15. The cargo lamp assembly of claim 13 , wherein the first inner optic is defined in a center portion of the inner lens, and wherein the second inner optic is defined on a border portion of the inner lens.

16. The cargo lamp assembly of claim 13 , wherein the outer optic is defined on a B-surface of the outer lens, wherein the outer optic includes a plurality of optic members, and wherein each optic member of the outer optic includes a curved upper surface and a planar lower surface.
