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 ...

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...

points of experience you need to know about led driver
28 Feb, 2022
Give up high-power and super-power, choose a high-stability small and medium-power power supply Because the greater the power, the greater the amount of heat generated, and the more compact the components inside, which is not conducive to heat dissipation, and the temperature is the culprit for the failure of the power supply. Furthermore, low-power 12v 200w led driver power suppl...

What are the characteristics of PWM dimming?
06 May, 2022
PWM dimming method is one of the commonly used LED power dimming technologies at present. This dimming technology is also called pulse width modulation technology, which is a traditional dimming method. Its working principle is to use simple digital pulses to repeatedly switch the LED driver. The system only needs to provide digital pulses with different width and narrowness to simply change ...

Which power supplies are suitable to buy?
27 May, 2022
At present, LED dimming power supply is mainly divided into three categories: LED triac dimming power supply,LED 0/1-10V dimming power supply and PWM dimming power supply. Among them, the LED triac dimming power supply is currently a widely used dimming method in LED dimming. It mainly uses the waveform of the input voltage to change the dimming. The advantages of this type of LED t...
