DIY LED lamp repair

Most of the LED lamps are made in China, and their quality is often poor. Statistically, two out of five LED bulbs stop working within the first year of use. Having bought three bulbs, you should be prepared for the fact that one of them will burn out in the next year.

LED bulbs do not burn out the same way as incandescent bulbs. If incandescent lamps simply stop giving light, then often the tungsten filament simply burns out in them. LED bulbs burn out differently. They begin to emit crackling sounds or smoke strongly (both options are possible at once), after which a strong crackle or pop often follows and the lamp stops working at all.

But in fact, in an LED lamp, some of its elements often simply fail, which can be eliminated with simple manipulations with a soldering iron. In order to fix this problem with your own hands, you need to unscrew the LED light bulb.

Next, you need to disassemble it by snapping off the light diffusing dome.

Very often, burned out LEDs become a problem due to which LED bulbs stop working. They burn mainly due to an incorrect or poor-quality installation. Burnt out LEDs can be replaced and in eighty percent of cases the LED bulb will be usable again.

Also, after opening, we check if the capacitor is damaged. With voltage surges, it is he who can cause the LED lamp to fail. To check if everything is in order with the capacitor, just remove the printed circuit board from the box of the LED lamp itself.

The photo shows that the capacitor did not just swell, but it exploded. The clap before the LED light stopped working and was the sound of a bursting capacitor. The broken capacitor will have to be replaced with a similar one..

It will not be difficult to find such a capacitor in radio component stores. It is advisable to find a completely identical.

After purchasing all the necessary parts, you can start repairing the LED lamp. First, using a soldering iron, you need to unsolder the burned out LED.

This is how a sealed LED looks like:

If you cannot find the LEDs you want, you can simply short-circuit the contacts directly. To do this, use solder and a soldering iron..

Shorted contacts should look something like this:

Our next step is to install a new capacitor. To do this, using a soldering iron and solder, we install a new capacitor in place.

After the capacitor is soldered, the LED bulb needs to be reassembled. To do this, install the printed circuit board back into the LED lamp housing, and close it on top with a light-diffusing cap..

Next, we screw the light bulb into its place. We do it with the lights off.

Turn on the switch and the LED light works again.

Now, dear readers, you have learned how to repair LED bulbs with your own hands..
