Abstract

An elongate automotive illumination assembly includes an elongate housing; at least one light source; an elongate lens having an apex region and a pair of spaced-apart blade portions. The spaced-apart blade portions extend away from the apex region to define a generally V-shaped cross-section with the apex region including an elongate light emitting surface. The blade portions connect to the elongate housing to define an enclosure. An elongate light guide guides light from the at least one light source to the elongate light emitting surface. The elongate light guide includes a body extending away from the light source(s) towards the elongate light emitting surface. The light guide is housed within the enclosure and between the blades of the lens such that the light emitting surface of the light guide is adjacent to the light emitting surface of the lens.

First claim

What is claimed is:

1. An elongate automotive illumination assembly including:
an elongate housing;
at least one light source;
an elongate lens having an apex region and a pair of spaced-apart blade portions extending away from the apex region to define a generally V-shaped cross-section with the apex region including an elongate light emitting surface, the blade portions connecting to the elongate housing to define an enclosure, the apex region of the elongate lens defines a first repeating wave pattern profile, the first repeating wave pattern profile having a first amplitude; and
an elongate light guide for guiding light from the at least one light source to the elongate light emitting surface, the elongate light guide including a body extending away from the at least one light source towards the elongate light emitting surface;
wherein the light guide is housed within the enclosure and between the blades of the lens such that the light emitting surface of the light guide is adjacent to the light emitting surface of the lens.

2. The assembly of claim 1 wherein the light guide includes a plurality of light-scattering particles.

3. The assembly of claim 1 wherein the light emitting surface of the light guide defines a second repeating wave pattern profile, the second repeating wave pattern profile having a second amplitude.

4. The assembly of claim 3 wherein the first repeating wave pattern profile matches the second repeating wave pattern profile.

5. The assembly of claim 4 wherein the elongate light guide has a rear region, the rear region having a third repeating wave pattern profile, the third repeating wave pattern profile having a third amplitude, wherein the third amplitude is smaller than the second amplitude.

6. The assembly of claim 1 wherein the apex region is light transmissive.

7. The assembly of claim 1 wherein each blade portion includes an opaque portion.

8. The assembly of claim 1 wherein the enclosure is weatherproof.
