First Claim
1. An electrical device configured to be installed within a device box, comprising:
- a housing including a plurality of terminals configured to be coupled to an AC power source;
a control circuit disposed in the housing, the control circuit including a processing circuit, an electronic switch, a plurality of light emitting elements and an ambient light sensor disposed on a substrate, the ambient light sensor being disposed proximate the plurality of light emitting elements on the substrate, the ambient light sensor being configured to provide the processing circuit with ambient light data, the processing circuit being configured to provide an electronic barrier between the plurality of light emitting elements and the ambient light sensor such that the operation of the ambient light sensor is not contaminated by light emitted by the plurality of light emitting elements;
a cover assembly coupled to the housing and including a lens element covering substantially the entire front face of the device, the lens element including an opening accommodating a switch actuator coupled to the electronic switch, the lens element and the switch actuator being comprised of a diffusing material, the lens element and the switch actuator being disposed over the plurality of light emitting elements such that the light emitted by the plurality of light emitting elements is diffused by the lens element and the switch actuator to emit a substantially uniform illumination without any shadow or hot spot artifacts being visible on either the lens element or the switch actuator.

Abstract
The present invention is directed to an electrical device that includes a control circuit having a processing circuit, an electronic switch, light emitting elements and an ambient light sensor disposed on a substrate. The processing circuit provides an electronic barrier between the light emitting elements and the ambient light sensor such that the operation of the ambient light sensor is not contaminated by light emitted by the plurality of light emitting elements. A cover assembly includes a lens element and a switch actuator comprised of a diffusing material. The lens element and the switch actuator are disposed over the light emitting elements such that the light emitted by the light emitting elements is diffused by the lens element and the switch actuator to emit a substantially uniform illumination without any shadow or hot spot artifacts being visible on either the lens element or the switch actuator.
