Abstract
An assembly includes a collimator having one end associated with a light source, a pillow lens associated with the collimator, and at least one surface that is non-coplanar with the pillow lens. The assembly further includes at least one light pipe, wherein a first portion of light is directed through the pillow lens and a second portion of light exits the pillow lens and is directed by the at least one surface into the at least one light pipe.
Claims25
An assembly, comprising:
- a collimator having one end associated with a light source;
- a pillow lens associated with the collimator;
- at least one surface that is non-coplanar with the pillow lens;
- at least one light pipe, wherein a first portion of light is directed through the pillow lens and a second portion of light exits the pillow lens and is directed by the at least one surface into the at least one light pipe;
- and
- wherein the at least one light pipe comprises a curved outer surface.
