Abstract
In one aspect, a light-mixing system is disclosed, which includes a light pipe having an input surface configured for receiving light from a light source, a light-mixing segment optically coupled to the input surface, and an output surface optically coupled to said light-mixing segment through which light exits the light pipe. A putative vector normal to at least one of the input or the output surface forms a non-zero angle relative to a longitudinal axis of the light-mixing segment. In some embodiments, the non-zero angle can be, for example, about 90 degrees.

A light-mixing system, comprising:
- a light pipe comprising:
- an input surface configured for receiving light from a light source,
- a light-mixing segment optically coupled to said input surface,
- an output surface optically coupled to said light-mixing segment through which light exits the light pipe,
- wherein a vector normal to at least one of said input and output surface forms a non-zero angle relative to a longitudinal axis of said light-mixing segment.
A light pipe, comprising
- a curved light-guiding waveguide extending from a proximal end to a distal end, said curved light-guiding waveguide comprising an input surface at said proximal end configured to receive light from a light source and an output surface at said distal end.
