Abstract
A light emitting device is provided. The light emitting device includes a first light emitter comprising a plurality of light emitting elements configured to emit light in a visible light region, a second light emitter comprising a plurality of light emitting elements configured to emit light in an ultraviolet B (UVB) region, and at least one processor configured to control the first light emitter and the second light emitter so that a sum of an intensity of light emitted from the first light emitter and an intensity of light emitted from the second light emitter is greater than or equal to a threshold illuminance value.
