Abstract: A lighting wall controller can be a retrofit for existing light switches, and the lighting wall control replaces the conventional light switch and can still work as a conventional light switch or other power switch with “dumb” lights or appliances while providing the ability to control “smart” lights and/or other “smart” devices with voice commands. In addition to controlling lights and/or devices, voice commands can be used to provide information or actions back to the user in response to the voice command. The lighting wall controller thereby provides voice control functionality without requiring additional devices, such as additional voice control appliances.

Abstract: A lighting apparatus a first group of at least one first solid state emitter, each first solid state emitter including a first light emitting diode (“LED”) that, when excited, emits light having a peak wavelength in a range between about 440 nm and about 475 nm, and a second group of at least one second solid state emitter, each second solid state emitter comprising a second LED that, when excited, emits light having a peak wavelength in a range between about 390 nm and about 415 nm. Between about 2% and about 15% of a spectral power of light emitted from the lighting apparatus is light having wavelengths in the range between about 390 nm and about 415 nm.
