First of all, European crystal chandeliers are basically purchased in the past few years!
The European crystal chandelier is probably from a few years ago, so it probably needs some cleaning now.
Among them, how to clean the crystal chandelier?
The crystal chandelier contains pendants. That is, the crystal ball accounts for a relatively large proportion. How to clean the crystal ball? This is relatively troublesome!
Because if there are many crystal balls on a lamp, it will be more cumbersome to operate.
Everything must be taken down and cleaned before hanging the crystal ball on it. The small accessories on the original pendant must be purchased online. Just go and buy it!
After purchasing, it feels a little more complicated to hang them up individually when you come back!
If you just buy a new one, it can be solved and it will be more convenient!
If you have sufficient funds, you can focus on doing these things according to your own situation.
This one is relatively simple, just take off the cover and rub the crystal ball on it, and it can be solved.
This kind of thing is relatively complicated. It is best to send a picture so that we can give you a specific reply.
Crystal chandelier repair
My neighbor’s European crystal chandeliers didn’t light up at all. It was actually just a bunch of glass balls. It was said that I bought it for more than 1,000 yuan.
I asked if I could repair it, so I asked my neighbor to take it down and take a look.
The inside is not as beautiful as the outside.
A bunch of LED lamp beads are connected in series, a switch is used to control whether the LED lights up or the bulb lights up or they light up together, and there is an LED driver.
Using an adjustable power supply, he tested the LED lamp beads one by one and found that seven or eight of them did not light up, so he asked him to dig out the spare lamp beads and replace them (the pins were already embroidered as a gift from the seller, and they were scratched one by one to brighten them).
I tried the whole thing and found that it still didn’t light up, so I disassembled the switch and checked the whole thing, and found that there were no signs of burning.
Since it is a switch, I bypassed the experiment first and connected both circuits directly to the mains. I found that both the bulb and the LED can light up. It seems that only the switch is broken.
So I disassembled the switch, and it looked like this on the outside:
There doesn’t appear to be any signs of burning inside.
Using tc2608, I searched the Datasheet and the typical circuit on the Internet as follows:
I connected it to 220v for testing, and there was no sound as in the online situation. So I tested the relay offline and applied 12v power and found that it can be closed. It seems that the relay is not broken.
According to the circuit, we can know that by bypassing c1 and adding 12v DC, we can test the DC scenario of the entire circuit. So we applied power between the bridge and c1 and found that the relay can also be closed. It can be speculated that c1 may be broken.
The bridge was tested online and the capacity was found to be incorrect.
I took it apart and tested it offline, but it didn’t work properly either.
The capacitance range of the multimeter is also the same
So I found one from the parts box and installed it. It was a bit small and I didn’t know if it would work.
Then connect it to 220v and test it. It is found that the relay can be closed. After putting it back, the lamp is repaired.
