What is the maintenance and replacement method of Led ceiling lamp?
The LED Down Light indoor does not turn on, mainly due to two reasons, one of the problem is the indoor light source, and the other is the problem of the power supply. At present, the light source of Led Indoor light is composed of patch Led lamp beads. First, disconnect the power at home, open the lampshade, and use a multimeter to measure whether the Led down light indoor source is broken (the lamp beads are generally connected in series), if it is , Then look at the style of the light source, go to the Lighting City to buy the same light source and replace it. When buying, pay attention to the voltage range of the light source and buy the light source of the same voltage.
If there is no problem with the light source detected by a multimeter, it depends on whether it is a power supply problem. Generally, Led ceiling lamps use an external power supply, so just buy a power supply to replace it.
