How to use a constant voltage dimming power supply to dim LED strips?

Most lighting projects require dimming functions. In order to realize the dimming function of the LED light strip, we need to consider whether the LED light bar and the power supply/controller/dimmer have the dimming function when using the led light strip. This article mainly introduces how to use a constant voltage dimming power supply to dim LED strips.

How does the LED SCR dimming (Triac dimming) work?

SCR is the abbreviation of Silicon Controlled Rectifier, which is a kind of high-power electrical component, also called thyristor. The Triac is equivalent to the connection of two thyristors in structure.

What is DALI dimming?

When multiple lamps need dimming, we can use DALI dimming to replace 1-10V dimming. DALI dimming is a typical digital control method.

3 kinds of LED dimming power supply

At present, the most commonly used LED dimming power supplies are: LEDTriac dimming power supplies, LED 0/1-10V dimming power supplies, and PWM dimming power supplies.
