Electrical lighting device

A light emitting wiring device for selectively illuminating a space, the device comprising:

• a housing including a plurality of wiring terminals configured to be connected to a source of electrical power;
• at least one circuit disposed in the housing, the at least one circuit being configured to provide an output signal in response to at least one external input signal;
• an emission-detection assembly including,
• a lamp sub-assembly coupled to the at least one circuit, the lamp sub-assembly including at least one light emitting element configured to emit light in response to the output signal,
• an ambient light sensor sub-assembly coupled to the at least one circuit and including an ambient light sensor and a sensor housing assembly, the ambient light sensor being configured to generate the at least one external input signal in response to an ambient light level in the space, the sensor housing assembly being configured to substantially isolate the ambient light sensor from the light emitted into the space;
• and
• a lens cover coupled to the housing, the lens cover including a major surface shape and size corresponding to a shape and size of a standard wall plate opening, the major surface including a lens array disposed therein, the ambient light sensor sub-assembly being disposed within a region formed by the lens cover, the ambient light sensor sub-assembly being disposed within a region formed by the lens cover, the lens array being configured to direct the light emitted by the at least one light emitting element into the space.
