Abstract
A light emitting apparatus disclosed herein comprises a first control apparatus, a first light emitting device, a sense apparatus, a second control apparatus, a power source and a second light emitting device, wherein the second light emitting device is electrically connected to the power source which is not connected to the first light emitting device. The sense apparatus senses both temperature and current of the first light emitting device to generate a second driving signal. The second driving signal is then provided to control the second light emitting device to emit a light for compensating the CCT shift of the light emitted by the first light emitting device.
