LED intelligent dimming power supply is an important part of modern lighting utilization. We found that light can produce multiple functions through LED intelligent dimming power supply.

For example, through color changes to create a more comfortable environment, such as adjusting the brightness of lights to achieve the purpose of energy saving and emission reduction, these can all be achieved through led dimming driver. Most of the constant voltage LED dimming is achieved by controlling the power supply of the driver.

The LED intelligent dimming power supply has been applied to incandescent lamps and energy-saving lamps earlier, and is currently the most widely used LED dimming method. Its working principle is to generate a tangential output voltage waveform after cutting the input voltage waveform through the conduction angle.

Applying the tangential principle can reduce the effective value of the output voltage, thereby reducing the power of the ordinary load (resistive load). The advantages of thyristor dimming are high working efficiency and stable performance.

When the lamp needs to be dimmed by the thyristor signal, due to the change of the thyristor conduction angle, the input voltage waveform in the circuit deviates from the sine wave, which changes the effective value of the input voltage, and the dimming is realized by changing the voltage.
