Abstract
A light-emitting device includes a dimmer, a rectifier, a first light-emitting module, a first controller, a second light-emitting module and a second controller. The dimmer is coupled to an alternating current for modulating the alternating current into an alternating signal. The rectifier couples the dimmer to the alternating current for rectifying the alternating signal into a direct current signal. The first light-emitting module is for emitting a first light with a first color temperature. The first controller is coupled to the first light-emitting module for controlling the first light-emitting module to emit the first light. The second light-emitting module is for emitting a second light with a second color temperature different from the first color temperature. The second controller coupled to the second light-emitting module for controlling the second light-emitting module to emit the second light.
