In one aspect, a light pipe is disclosed. In some embodiments, the light pipe comprises an input section including a waveguide having a circular cross section; and an output section having a polygonal cross section, wherein the input section has an input surface for receiving light from one or more light sources and an output surface through which light exits the input section, and the output section has an input surface optically coupled to the output surface of the input section to receive at least a portion of the light exiting the input section, and an output surface through which light exits the light pipe.

Low-profile color-mixing lightpipe

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.
