Lens assembly for an automobile light assembly having LED light source
First Claim
Patent Images
1. A light assembly for an automotive lighting application, the light assembly directing light along a longitudinal axis, the light assembly comprising:
- a LED light source having a cover lens;
a first lens member having a recess receiving the LED light source, the first lens member including a radial portion and an axial portion defining the recess;
a second lens member having an interior space receiving the first lens member, an outer surface of the second lens member defining a reflecting surface; and
the reflecting surface of the second lens member receiving light passing through the radial portion of the first lens member and through an inner surface of the second lens member, the reflecting surface directing the light downstream along the longitudinal axis through the second lens member.

Abstract
A light assembly is provided having a lens assembly that splits the function of a near field lens into two components, thereby permitting a manufacturable lens that achieves the desired beam size and intensity. At the same time, increased flexibility and control over the beam spread characteristics is achieved. The first component is an inner lens, while the second component may be a reflector or a second lens.
