US 9,433,054 B2 · Light emitting apparatus with ambient light sensor

Abstract

Disclosed herein is a light emitting apparatus. The light emitting apparatus includes a first light emitting unit including a first light emitting diode and a first phosphor; a second light emitting unit including a second light emitting diode and a second phosphor; an ambient light sensor, and a controller. The ambient light sensor detects a spectrum distribution of ambient light, and the controller operates the first and second light emitting units with reference to the spectrum distribution of the ambient light detected by the ambient light sensor. A light emitting unit is divided into two or more light emitting units and the ambient light sensor is provided to operate the first and second light emitting units corresponding to the spectrum distribution of ambient light.
