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...

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...

Does LED drive power determine the life of LED lamps?
17 Dec, 2021
Constant current source drive is the best way to drive LEDs. It uses constant current source to drive, no need to connect a current limiting resistor in the output circuit, and the current flowing through the LED is not affected by external power supply voltage changes, environmental temperature changes, and the discreteness of LED parameters. Therefore, the current can be kept constant and the va...
