Common problems with corn row led light choose during overhaul from tangram's blog

Common problems with corn row led light choose during overhaul:

1, antistatic: Because LED is electrostatic induction photoresistor, if the maintenance corn row led light choose not to do a good job of antistatic countermeasures, it will burn LED, leading to consumption. Here it is necessary to pay attention to the anti-static electric iron must be used, and maintenance personnel also do a good job of anti-static countermeasures (such as wearing electrostatic induction ring and anti-static gloves, etc.).

2. High temperature weather: led and FPC, two key components of corn row led light choose, are all heat-resistant commodities. If the FPC is in high temperature or beyond its bearing temperature, it will make the FPC covering film bubble, immediately leading to the destruction of corn row led light choose. In addition, LED can not be constantly heat resistant, in high temperature time for a long time, its chip will be burned by high temperature. Therefore, when inspecting and repairing corn row led light choose to choose the electric iron must choose the temperature control electric iron, the temperature is limited in a category, it is strictly prohibited to change and set. In addition, even so, it is necessary to pay attention to the maintenance, the electric iron should not stay in the LED pin time beyond 10 seconds, if beyond this time, it is likely to burn the LED chip.

3, short circuit fault: many corn row led light choose poor is because the foot is located in a short circuit fault, must find out the reason before maintenance. Otherwise, after replacing the LED carelessly, it will continue to cause the chip of the LED to be penetrated by short circuit capacity when plugging again. Therefore, before replacing the new LED, it is necessary to find the reason first, so that symptomatic treatment can achieve half the result with less effort.
