Patent ID: 7837359

Claim:
A light assembly, comprising: a LED light source; a lens including a body defining a front side and a rear side and formed of a light-transmitting material, the rear side of the body having a generally frustum-shaped cavity defining a first inner surface portion facing the LED, wherein the first inner surface portion is generally conical, and a base inner surface portion defining a rear lens surface facing the LED, the body further defining a tapered outer surface on the rear side of the body, the body further defining a front surface on the front side of the body, the front surface including a front lens surface portion having a convex surface and a collimating front surface portion extending around the front lens surface portion, wherein the collimating front surface portion includes a ring-shaped planar portion, first and second ring-shaped planar portions, and an inwardly-facing transverse surface extending between the first and second ring-shaped planar portions; and wherein: a first portion of the light from the LED light source travels into the body through the rear lens surface, and escapes from the front lens surface portion, a second portion of the light from the LED light source travels into the body through the first inner surface portion, is internally reflected within the body at the tapered outer surface, and escapes from the body through the collimating front surface portion, and the first and second portions of the light at least partially combine after escaping from the body and define a target area that is spaced-apart from the body, and wherein the first and second portions of the light together provide a generally uniform light intensity distribution over a substantial majority of the target area.
