Classification: CPC A | IPC A

Claim 23:
24. A light emitting device comprising:
a substrate wherein the substrate is a circuit board further comprising an on-board controller and wherein the circuit board is in the form of a circle with a hole in the middle; and
a plurality of light emitters disposed on the substrate and configured to emit a light to inactivate microorganisms on a surface a distance away from the substrate;
wherein to emit the light, the plurality of light emitters are further configured to produce a radiometric power that satisfies a threshold, wherein the threshold is based on a target irradiance at the solid surface sufficient to initiate inactivation of the microorganisms on the surface;
wherein the radiometric power is based on:
a number of the one or more light emitters,
beam angles of the one or more light emitters, and
the distance; and

wherein the light emitted by the plurality of light emitters comprises:
a proportion of a spectral energy of the light, measured in a 380 nanometers (nm) to 420 nm wavelength range, of at least 50%; and
a full width half max (FWHM) emission spectrum of less than 20 nm and centered at a wavelength of approximately 405 nm to concentrate the spectral energy of the light and minimize energy associated with wavelengths that bleed into an ultraviolet wavelength range.
