Abstract
A laminated light guide and component carrier includes a light guide of a light transmissive polymeric material. The light guide has a pocket in a first face. First electrical traces are printed on the first face. A light emitting diode is positioned in the pocket and supported on the light guide by attachment legs which extend outward from the pocket electrically connecting the light emitting diode to the first electrical traces. A light reflector is formed as a texturally modified area of the light guide directly aligned with the light emitting diode. A capacitive touch sensor is printed on a light guide second face and connected to second electrical traces defining capacitive touch traces printed on the second face. A window region of the light guide is defined where the capacitive touch sensor is aligned with the light reflector and the light emitting diode.
