Abstract:
Disclosed wherein is an electrical faceplate, such as a cover for a wall outlet or light switch, that uniformly illuminates by receiving light into a transparent lightguide, homogenizing the light within the lightguide and scattering the homogenized light preferentially through a front surface. In one embodiment a faceplate comprises a substrate operable to cover an interface between an electrical junction box and a wall. The faceplate further comprises a light receiving surface operable to receive light from a light generation component (e.g. an LED) and transmit the light substantially parallel to a front surface, thereby promoting reflection at the front surface that homogenizes the light intensity within the faceplate and a portion operable to scatter light through the front surface. Several embodiments provide a faceplate with a lightguide to homogenize light through a process of total internal reflection to provide uniform illumination of the faceplate.
