How to deal with the problem of LED dimming and flickering?
29 Nov, 2021
Normally, the human eye can perceive light flicker with a frequency of 70 Hz, but it will not perceive it at a frequency higher than this frequency. Therefore, in the LED dimming driver lighting application, if the pulse signal has a low frequency component with a frequency lower than 70 Hz, the human eye will feel flicker. The flicker is generally caused by the loop current not reachin...

Questions of LED lights and led driver in project
08 Oct, 2021
*Why can't the lamp cup (tungsten wire) of the same power be lit with the same 110v dc led driver? When the lamp cup is in the cold state, its resistance is very small, that is, when the rated voltage is applied to the lamp cup, a large starting current is required immediately before lighting. When the lamp cup is lit, the temperature rises, the resistance value increases sharply, and the current ...

What are the characteristics of PWM dimming?
27 Sep, 2021
PWM dimming is currently a mainstream dimming technology used in LED dimming power supply products. In the circuit of the analog signal, the brightness change of the lamp is controlled by the digital output. Compared with traditional analog signal dimming, this dimming method has many advantages. The basic principle of pwm dimming led driver can be understood as connecting a ...
