The ring light on the roof of my kitchen is broken

The ring fluorescent lamp does not light up, which is usually caused by the aging of the lamp and the damage of the rectifier; Repair is only necessary to purchase the corresponding 2 parts to replace.

Maintenance sequence: Turn off the power ---

Unplug the connecting socket of the lamp and the rectifier (you can see it, there are 4 pins, it is a rectangle and not a square)--

Remove the --- of the lamp by simply pulling the spring hook on the lamp

Cut the 2 power cords on the rectifier ---

The ballast --- can be removed by loosening the fixing screws at both ends of the rectifier with needle-nose pliers and removing the nuts without the gap

The model (power) on the lamp and rectifier can be purchased in the lamp market or in a larger hardware store.

The price is about 20 yuan for a set of ordinary medicines, and 50-60 yuan for drugs with better brands.

Install in reverse order (or remind the direction of the 4 pins to be aligned).

Is it circular? The general price is about 10 yuan, and the lamp stores are all sold.

One; diameter 5 dm; It's too big. GENERALLY 25---30MM IS BIG ENOUGH.

Two; After buying, the base is fixed with the wood inside, connected to the wire, and that's it.

Three; Lamps and lanterns are sold in stores.

Measure the size, remember the model, take a picture with your mobile phone, and then go to the lighting store to ask, and let the person in the store teach you by hand before checkout, and then pay after you learn to pay. No matter how clearly it is said in words, it is better to teach you by hand.

Ring lights are all sockets, they are sold in larger supermarkets or home appliance markets, they are very easy to install, unscrew the cover and insert it into the socket OK, note: The interface of the ring light is fragile, be careful when installing.
