1. Analysis of maintenance method of living room chandelier
1. Before maintenance, the power must be turned off to avoid unnecessary damage. Be careful when you remove the living room chandelier. There are two spring buckles behind the chandelier, so don't hurt yourself. Remove the original living room chandelier and replace it with a new one. If it turns on, it means that the original living room chandelier is broken. If it still doesn't turn on, remove the driver and use tape to seal the driver and power cord tightly. Connect the chandelier to the driver. If it is on, it means the driver is broken. Both the driver and the living room chandelier can be purchased by yourself.
2. Before repairing, you should understand how the chandelier is composed, because all lamps have different powers and different appearance sizes, and each has its own corresponding power drive. For example, a 3 watt living room chandelier needs to have a stable output The internal structure of the 3 watt drive living room chandelier. The 3 watt living room chandelier is three small 1 watt lamps connected side by side. Usually the driver and the living room chandelier have a fixed interface.
3. Usually, if the chandelier in the living room does not light up without power failure, either the driver is broken or the led light itself is broken. So get a good driver and try the living room chandelier. Generally, the living room chandelier is on the ceiling. We have to take an escalator or a stool to repair it. Usually, we can use a small suction cup to plug a screwdriver, and use the suction cup to suck the bottom of the living room chandelier and easily suck it down.
2. Precautions for maintenance of chandelier
1. Anti-static steps must be taken when repairing the living room chandelier. Because the light bulb is a static sensitive device, it is easy to burn the light bulb if the anti-static steps are not done well. Therefore, the soldering iron used during maintenance must be an anti-static soldering iron, and the maintenance personnel must also wear anti-static tools such as static rings and anti-static gloves.
2. Prevent continuous high temperature when repairing the chandelier. In general, the bulb is made of LED and FPC, both of which are products that cannot withstand continuous high temperature. If the continuous high temperature will cause the FPC cover film to bubble, causing the LED bulb to become useless. If the high temperature is too long, the chip of the LED bulb will be burnt. However, the soldering iron used when servicing LED bulbs must be a soldering iron that can maintain a constant temperature to keep the temperature within a limit.
3. The real cause of the failure must be found during maintenance. However, many chandelier failures are caused by short circuits at the pins, which must be observed clearly before repairs. Otherwise, careless maintenance will still not achieve the effect of maintenance.
