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.
Claims20
A disinfecting LED lighting system comprising:
- at least one light fixture disposed in a ceiling in an environment and configured to output a first light and a second light, wherein the first light and the second light are emitted from independent sources and operate independently;
- and wherein:
- the first light and the second light both emit a portion of a spectral range as a disinfecting energy within a disinfecting wavelength range of 380 to 420 nanometers,
- the first light emits a first output wherein at least 20% of the spectral range is within the disinfecting wavelength range;
- and
- the second light emits a second output wherein at least 70% of the spectral range is within the disinfecting wavelength range;
- and
- at least one sensor in communication with the at least one light fixture and configured to detect a characteristic of the environment, wherein the characteristic of the environment is an amount of disinfecting energy, and wherein the at least one sensor is configured to detect an amount of natural light disinfecting energy and detect an amount of disinfecting energy of the first light and the second light within the disinfecting wavelength range of 380 to 420 nanometers;
- and
- a controller in communication with the at least one sensor and the at least one light fixture and configured to cause an event.

A method of LED lighting disinfection comprising:
- outputting, via a first light disposed within a first light fixture in an environment, a first output comprising at least 20% of emitted wavelengths within a disinfecting wavelength range of 380 to 420 nanometers (nm);
- outputting, via a second light disposed within a first light fixture in an environment, a second output comprising at least 70% of the emitted wavelengths within the disinfecting wavelength range of 380 to 420 nm, wherein the second light is an independent source from the first light;
- detecting, via a sensor in communication with the first light fixture, a characteristic of the environment, wherein the characteristic of the environment is an amount of disinfecting energy, and wherein the sensor is configured to detect an amount of natural light disinfecting energy and detect an amount of disinfecting energy of the first light and the second light within the disinfecting wavelength range of 380 to 420 nanometers;
- and
- causing an event, via a first controller in communication with the sensor and the first light fixture.
