Disclosed are a light-emitting device for digital control of color temperature modulation and its application. The light-emitting device is electrically connected to a wall switch and includes a DIP switch, first LEDs, second LEDs and a control module. The control module is electrically connected to the above components and contains a truth table. The truth table includes at least a first mode, second mode, third mode and a memory and automatically switch mode, and a digital switching is accomplished by correlating the DIP switch to the truth table. In the memory and automatically switch mode, the first to third mode color temperatures are sequentially switched and controlled by turning on or off the wall switch according to the truth table information. The light-emitting device may be applied to light fixtures or mirror products to improve the convenience of use.
