The dimming power supply adjusts the brightness of the light by changing the output voltage and current of the power supply through the dimming signal input to the power supply.

The biggest difference between the ordinary power supply and the dimming driver is that the ordinary power supply only has the switch function. The dimming power supply can adjust the brightness, color, etc. of the light according to the comfort of the human eye, the environment or the needs of the scene.

The dimming power supply adds a dimming control module inside the power supply, and controls the power supply through an external signal source to change the illuminance and color temperature of the light source.

The biggest difference between it and ordinary power supply is controllable. The conventional power supply has only two working states, start/stop, and the dimming power supply adds a variety of working states according to its dimming method, so that one light source can meet more lighting needs.

The working principle of dimming is to achieve the LED dimming function by controlling the output of the current, voltage and frequency of the LED. The biggest difference between the dimming power supply and the ordinary power supply is that the brightness or color temperature of the LED can be adjusted.
