In recent years, the LED indicator switch has developed rapidly in the market and brings a good product experience to the consumers. However, the occasional complaints are also heard in the sale, reflecting the individual LED lights controlled by the LED indicator switch, and there is still a faint flicker after the closing of the switch. Should I change the light or switch?

Our inspection and test found that such a phenomenon is not a problem of switching. When the switch with the LED indicator is closed, there will be a over current phenomenon, but the electricity is extremely small. Only twenty or thirty micro ampere (one micro ampere equal to one millionth of a) is almost equivalent to static electricity. Under normal circumstances, no matter whether it is a fluorescent light source or a LED light source, it will not cause flicker after closing, so it appears. In the above case, the problem is still on the power supply used in the LED lamp.

At present, there are two main kinds of power supply used in LED lamp, one is isolation power, the other is non isolation power, and the non isolation power is low in cost, but there is a big hidden danger in the aspect of product life and safety.As the competition of the LED lighting market is becoming increasingly hot, the price is often a competitive weapon, not only a small factory, but also to relax the demand for the quality of the product for the cost, and even some of the big lighting brands. In some of its products, there are such phenomena.

In this case, I think at least two points can be done: one is the attitude, the appearance of such a complaint, is it should change the light, or switch, our attitude is to change the light, no matter what brand it is, good is good, bad is not good, can not let bad money expel good money. Second, we should promote the related products to set up national standards as soon as possible and expose the problems to the sunshine, so as to standardize the healthy development of LED lighting industry.
