Abstract
A molded component assembly includes a printed circuit board with a first face and a second face, and multiple through apertures. Multiple light emitting diodes are mounted on a first portion of the first face. A light guide of a light translucent polymeric material is positioned proximate to the light emitting diodes. The light guide includes: a contact surface directly contacting the first portion of the first face; multiple light outlets, each aligned to receive visible light emitted from one of the light emitting diodes; and multiple integrally formed light reflectors. Each light reflector extends into one of the light outlets and over one of the through apertures, and each includes a first reflector surface, a second reflector surface and a third reflector surface each oriented non-orthogonal to the contact surface to reflect light from one of the light emitting diodes into one of the light outlets.
