Cautions in Maintenance of LED Lamp Belt

In recent years, LED is gradually becoming an indispensable part of people's daily life, and the LED lamp band is being used more and more by people, from home to entertainment and outdoor, everywhere. Although the life of the LED is very long, but it also has broken time, so when the LED is damaged, how to repair it? Let's take a look.




1. LED is an electrostatic sensitive element. If the anti-static measures are not taken when repairing the LED lamp band, the LED will be burned out, which will not be repaired properly, and will result in waste of resources. So it is necessary to do a good job of anti-static treatment. The soldering iron used in maintenance must be anti-static soldering iron, and maintenance personnel should also wear anti-static ring and anti-static gloves and other anti-static measures.




2. The two core components of LED lamp band, LED and FPC, can not sustain high temperature resistance. FPC will blister the covering film of FPC under the condition of continuous high temperature, which will directly cause the discarded LED lamp band. LED also can not sustain high temperature, in high temperature condition for a long time, the chip will be burned. So the soldering iron used in repairing the LED lamp band must be temperature-controlled soldering iron. The temperature should be set in a safe range, and the stability should not be set too high at will. Also need to pay attention to the repair iron can not stay in the foot of the LED for too long, preferably not more than 10 seconds, if more than this time, it is likely to burn the LED chip.




3. Many LED lights with bad contact sometimes, or illumination is not bright, this is because there is a short circuit at the foot. Maintenance personnel should first identify the real bad reasons before maintenance. Otherwise, when the bad LED is replaced directly, it will continue to cause the chip of the LED to be broken down by short circuit current when it is powered on again. So before replacing the new LED, we must first find out the real reason, so that we can completely repair it, so that there will be no problems after repair.




When repairing the LED lamp belt, it's better to find professional maintenance personnel and try not to repair it by experiment, which will cause potential safety hazards in use. More knowledge about LED bands will be shared with you.
