Abstract: 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 white light comprising a wavelength range of 380 to 420 nm, and cause output, via a second light emitter a non-white light comprising a wavelength range of 380 to 420 nm.

Abstract: 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.

Abstract: Control systems for disinfecting light systems and methods of regulating operations of disinfecting light systems are disclosed. The control system may include a controller operably coupled to a disinfecting light fixture illuminating a space. The controller may regulate an operation of the disinfecting light fixture by adjusting an amount of disinfecting energy provided to the space by the disinfecting light fixture and/or adjusting an amount of illuminating light provided to the space by the disinfecting light fixture. The amount of disinfecting energy may be adjusted based on data relating to the space including disinfecting energy provided to the space, a bacterial load of the space, and/or environmental characteristic(s) of the space. Additionally, the amount of illuminating light may be adjusted based on data relating to the space including environmental characteristic(s) of the space, and/or a predetermined operational schedule for the space.
