Electrical wiring device

摘要

The present invention is directed to an electrical wiring device that includes at least one circuit configured to provide an output signal in response to at least one external input signal. The device further comprises a light emission and detection assembly that includes: a lamp sub-assembly coupled to the at least one circuit, the lamp subassembly including at least one light emitting element configured to emit light in response to the output signal; and 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 sensing an ambient light level in the space, the sensor housing assembly being configured to substantially isolate the ambient light sensor from the light emitted by the lamp sub-assembly.
