There is something wrong with the LED ring lamp at home. How to disassemble, replace and install it? The following briefly introduces the disassembly process of LED ring lamp for reference.

1. Remember to cut off the power supply before any lamp device is repaired.

2. Then remove the LED ring lamp together with the whole light.

3. The LED ring lamp is fixed on the lampshade by three metal fixing rings. Pull out the metal fixing ring before disassembling the lamp.

4. Generally, there is a well connected connecting line at the bottom of the lampshade. After the new lights with the same specification and model are better, the connector of the connecting wire can be directly inserted into the annular lamp tube.

5. After the wiring of LED ring lamp is completed, the lampshade can be directly installed.

If after connecting the power supply, it is found that the LED ring lamp still does not light after replacing the lamp tube, it may be a problem with the ballast of the LED ring lamp, and replacing the rectifier involves a wiring problem.

1. There is no distinction between single ballast wiring, that is, the zero line and the front can be connected casually (the front is white / red, and the zero line is black).

2. The wiring of double ballast is generally brown wire connected to the front, blue wire connected to the zero wire, and the remaining two wires are ground wires. It is good to directly connect the ground wires.
