Electric Light Radiant Energy Control Systems

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.

AI Technical Summary

Benefits of technology

Enables efficient and safe disinfection in occupied spaces by dynamically adjusting disinfecting energy and illuminating light, ensuring effective bacterial control while eliminating the need for hazardous UV light and extensive safety protocols.

Problems solved by technology

UV systems include remote controlled robots and lockable rooms, which can only be used when a room is not occupied, which is not always feasible.
