Patent ID: 7758234

Claim:
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; and an emission-detection assembly including, a lamp sub-assembly coupled to the at least one circuit, the lamp sub-assembly including reflective portion and a reflective portion and at least one light emitting element configured to emit light in response to the output signal, and an ambient light sensor sub-assembly including a housing portion integrally formed in the reflective portion including a housing portion integrally formed in the reflective portion 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.
