What are the important indicators of LED dimmable power supply?
02 Aug, 2021
How much do you know about the indicators of LED dimmable power supply? In fact, there must be two points in terms of quality. The rest depends on the indicators. 1.Look for the brand of capacitors, of course, the price is more expensive than other non-brand capacitors. But the quality is guaranteed. 2.Whether with IC control chip, IC control chip has protection functions such as short-circui...

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...

What should be considered in the design of led power supply?
30 Aug, 2021
The circuit of the 24v led drive power supply is composed of electronic components, including semiconductor components, resistors, and LEDs as cold light sources. The operating junction temperature cannot exceed the limit, and a certain margin should be left in the design. The design of the entire luminaire should consider the beautiful appearance, convenient installation, light dis...

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 ...
