Abstract
A molded component assembly includes a printed circuit board with a first face and an oppositely facing second face. Multiple light emitting diodes are mounted on a first portion of the first face. Multiple electronics components are mounted on a second portion of the first face. A light guide of a light translucent polymeric material has a contact surface directly contacting the first portion of the first face and multiple light outlets defining cavities in the light guide. The light guide is seated over the light emitting diodes and directly receives visible light from the light emitting diodes and transmits the visible light to the light outlets. A reflector plate directly contacts the light guide and extends over the second portion including the electronics components, and includes filler members extending into the light guide. The reflector plate reflects visible light back into the light guide.
