Go to the roadside to find a water and electricity installation shop, and ask the master to repair it, usually about dozens of yuan.
Yes, but you have to spend money, because it's the light in your house, not the door light in the hallway.
A broken light is generally a broken bulb, and replacing the bulb is fine. If the whole is not bright, find an electrician to check the line.
There is nothing convenient and inconvenient, power off, remove the LED, etc., use a multimeter to measure which one is broken, and replace it with a new one.
This can only be known after inspection, and no one can analyze the accuracy without inspection, and can only be known after removing the cover or even removing it as a whole for testing.
Of course it can be repaired, but the lamp is broken, take it down and replace it with a light bulb. That's an infrared light bulb. The power is about 300-500 watts. Generally, there are no coarse holes that should be found in electrical appliance stool messy parts stores.
