Patent ID: 8534890

Claim:
A light pipe assembly comprising: a light pipe elongated between opposite first and second ends along a longitudinal axis, the light pipe formed from a light transmissive material; and an optical concentrator joined to the first end of the light pipe, the optical concentrator including an end section and an opposite coupling end connected to the first end of the light pipe, the end section configured to receive light generated by a light source, the optical concentrator formed from a light transmissive material that conveys light through the optical concentrator, wherein the optical concentrator collimates the light generated by the light source into the first end of the light pipe, wherein an exterior surface of the optical concentrator includes an ellipsoid shape that is elongated along a major axis, wherein the exterior surface of the optical concentrator includes a cone shape that extends from the coupling end of the optical concentrator to the ellipsoid shape, and the ellipsoid shape extends from the end section of the optical concentrator to an interface between the cone shape and the ellipsoid shape.
