Abstract: The light-emitting device disclosed herein comprises a step down circuit and a current limit device, wherein the step down circuit prevents the current signal provided to the light-emitting device larger than the rating current value of the light-emitting device. Moreover, the current limit device only limits current signal while the power supply surges. The two stages protect circuit turn less power to heat.

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.
