At present, the most common and most commonly used LED dimming on the market include: LED thyristor dimming, LED 0/1-10V dimming, PWM dimming.
The other dimming working principle is to control the dimming function of the Led Panel Downlight by controlling the output of current and voltage and frequency.
Today, Led Square Panel Light Supplier talks about the three commonly used dimming methods and differences:
LED thyristor dimming:
The thyristor dimming has been applied to the dimming mode of incandescent lamps and energy-saving lamps earlier and is also the most widely used dimming method for LED dimming. SCR dimming is a physical dimming. Starting from phase 0, the input voltage is chopped until the thyristor is turned on. It works by cutting the waveform of the input voltage through the conduction angle to produce a tangential output voltage waveform. Applying the principle of tangential direction, the effective value of the output voltage can be reduced to reduce the power of the normal load (resistive load). The thyristor dimmer has the advantages of high adjustment precision, high efficiency, small size, lightweight, easy remote control, etc., and is dominant in the market. The advantages of thyristor dimming are high working efficiency and stable performance. The cost of dimming is low.
