LED linear lights need to be anti-static: because LEDs are static-sensitive components, if anti-static measures are not taken when repairing led linear lights, the LEDs will be burned and waste. It should be noted here that the soldering iron must use an anti-static soldering iron, and the maintenance personnel must also take anti-static measures (such as wearing a static ring and anti-static gloves, etc.)
Led linear lights cannot sustain high temperature: the two important components of led linear lights are led and FPC, and led linear lights are products that cannot continue to withstand high temperatures. If the FPC continues to high temperature or exceeds its withstand temperature, it will cause the FPC's cover film to bubble and directly cause the LED linear lamp to be scrapped. At the same time, the LED cannot withstand high temperature continuously, and the LED linear lamp chip will be burnt out by the high temperature after the high temperature time is long. Therefore, the soldering iron used when repairing the led light strip must be a temperature-controlled soldering iron, and the temperature is limited to a range, and it is forbidden to change and set at will. In addition, even so, it is necessary to pay attention to the soldering iron not to stay on the pins of the led line lamp for more than 10 seconds during maintenance. If it exceeds this time, the led line lamp chip may be burnt.
If the outdoor led line light does not light up, please check whether the circuit is connected, whether the connection is bad, and whether the positive and negative poles of the light bar are connected reversely. The brightness of the light bar is obviously low. Please check whether the rated power of the power supply is less than the power of the light bar, or the connection wire is too thin, which causes the connection wire to consume too much power. The front of the light bar is obviously brighter than the back. Please check whether the series length exceeds 3 meters.
According to the analysis of the material of the PCB board, the PCB board also has many quality levels. Most of the cheap line lights on the market use the secondary material PCB board, which is easy to delaminate after being heated and the copper foil is too thin. Easy to fall off and poor adhesion. The copper foil layer and the PCB layer are easy to separate, not to mention the stability of the circuit. Do you still expect the circuit to be stable when the board is like this? Don't be kidding, everyone is busy! Most of the cheap ones The linear lamp has not undergone reasonable circuit layout and inspection tests to evaluate its reliability and stability. The products produced by regular LED linear lamp manufacturers will certainly achieve this before they can be sold on the market.
