I believe that many people have encountered stroboscopic LED lights at home, which is very annoying, but they don"t know how to solve it. So today we will teach you how to solve this problem.

We have also checked some information on the Internet for this problem. According to relevant personnel, the light source strobe is essentially the light emitted by the light source showing a certain frequency and periodic change over time. It varies with time between different colors and brightness. Change and change. So what causes the LED lights to flicker?

Stroboscopic light can have varying degrees of impact on human health. Light source stroboscopic light can cause headaches, autism, visual fatigue and other neurological diseases. In severe cases, it can cause illusions in the human eye and cause some accidents. LED stroboscopic is actually related to the driver, if it is a good quality product, the driver uses a constant current circuit, isolated DC voltage output, the LED light source is very stable, and there will be no stroboscopic. So what is the reason for the LED stroboscopic? There are many poor quality products on the market. Directly use the mains power to limit the current through series capacitors, and double the voltage output, which is about 5 components. Such LED lights will not only occur Stroboscopic, and it is still live, so that not only stroboscopic, but also very easy to break.

So what is the solution?

1. The LED lamp board and the LED driver do not match. Under normal circumstances, a single 1W lamp bead can withstand a current of 280~300ma and a voltage of 3.0 to 3.4V. If the lamp chip is not of sufficient power, it will cause the frequency of the light source. The phenomenon of flashing, the lamp beads can not bear the high current, it will turn on and off, if it is serious, it will burn the lamp beads.

2. The drive power supply is damaged, just replace a power supply with the same specification.

3. The driving power supply has an over-temperature protection function, and the heat dissipation performance of the material of the lamp cannot meet the requirements. When the over-temperature protection starts to work, it will flash and flash.

4. If this phenomenon occurs in outdoor lamps, it is very likely that the lamps have entered water, and they will be broken if they flash slowly. This phenomenon can only be replaced with a new driver and waterproof measures.

The above are the reasons and solutions for the LED lights that we have summarized for everyone. I hope that I can help you here. If there is something wrong, I hope you can point it out. You can also comment on the points. supplement.
