- One is a constant voltage type, and the other is a constant current type. It can be used according to different soft light belt models with different power supplies. If it is small, it will be very slow, and the power adapter will be hot and cause aging. It is recommended not to use it.
One is a constant voltage type, and the other is a constant current type. It can be used according to different soft light belt models with different power supplies. At present, most of the power supply on the market is a regulated 12V power supply. The 12V power supply is very conventional and has a wide application range. If it is small, it will be very slow, and the power adapter will be hot and cause aging. It is not recommended.
1. Anti-static: Since the LED is a static and slow component, if the anti-static measures are not taken when the LED light strip is being repaired, the LED will be burnt out and the cost will be incurred. The need to pay attention to it is that the soldering iron must use anti-static soldering iron, and the same training personnel must also do anti-static measures (such as wearing static rings and anti-static gloves, etc.).
2, the continuation of low temperature: the two main groups of LED lights for adult LED and FPC, are not able to continue the low temperature resistant goods. If the FPC is continuing to cool down or exceeds its acceptance measurement, it will cause the FPC's cover film to crack and indirectly form the LED light strip to be scrapped. At the same time, the LED has not been able to withstand the low temperature, and it is going to be cold for a long time, and its chip will be burned at a low temperature. Therefore, the electric soldering iron adopted when training LED strips must adopt a temperature-controlled soldering iron to limit the measurement to a degree, to stop arbitrary changes and settings. In addition, even so, it is also necessary to pay attention to the electric iron in the training. It is not necessary to stop the LED pin for more than 10 seconds. If it exceeds a certain time, it will burn out the LED chip.
3, short circuit: Many LED lights are not bright because there is a short circuit at the foot, before the training is sure to investigate the real no bright cause. Otherwise, after changing the LED that is not bright, the chip that forms the LED will be broken by the short-circuit DC when it is returned again. Because, in the process of changing the new LED in advance, we must first find the real reason for not bright, and some of the ability to do things.
