Abstract

A light pipe assembly includes a light pipe and an optical concentrator. The light pipe is elongated between opposite ends along a longitudinal axis. The light pipe is formed from a light transmissive material. The optical concentrator is joined to the first end of the light pipe and includes an end section and an opposite coupling end connected to the first end of the light pipe. The end section is configured to receive light generated by a light source. The optical concentrator is formed from a light transmissive material that conveys light through the optical concentrator. The optical concentrator focuses the light generated by the light source into the first end of the light pipe.
