Working principle of 0 10v dimmable led driver
10 May, 2021
From the previous ordinary fluorescent lamps, electronic ballasts that used 0-10V to adjust the signal, to the current LED, it can be said that it has been widely used in Europe and the United States. Street lights use 0-10V as the dimming signal, and use the computer to automatically adjust. In the wee hours of the morning, when the usage is low, the brightness is automatically adjusted, and the ...

Triac dimming power supply knowledge
16 Aug, 2021
The working principle of triac dimming is to cut the input voltage waveform through the conduction angle to produce a tangential output voltage waveform. Using the principle of tangential direction, the effective value of the output voltage can be reduced, thereby reducing the power of the ordinary load (resistive load). The advantages of triac dimming are higher working efficiency and stable...
