摘要：
Radiant energy control systems, methods, and apparatuses are provided. An example light emitting device may comprise a sensor operable to detect whether a space is occupied, and a controller in communication with the sensor and operable to cause output, via a first light emitter for a first time period in the space, of a white light comprising a spectral energy of up to 30% energy in a wavelength range of 380 to 420 nm, cause output, via a second light emitter for a second time period in the space, of a non-white light comprising a spectral energy greater than 70% energy in the wavelength range of 380 to 420 nm, and switch, based on whether the space is occupied and to achieve a minimum dosage of light in the wavelength range of 380 to 420 nm during a third period that includes the first time period and the second time period, between causing output of the white light and causing output of the non-white light.
