LED panels tend to occasionally fail but the most common fault that these panels and their drivers experience is a capacitor failure because of the heat exposure and because they are being constantly pushed to their limits.
In this video, I'm guiding you to how these drivers operate, how they are made, and what you can do to repair them.
Since in most cases, the LED panel itself is not damaged, these repairs are well worth the time of an afternoon to fix a bunch and have them ready for replacement once another one fails.
To repair an LED panel you will need:
6.8uF 400V Capacitor - s.click.aliexpress.com/e/_DDt...

Good explanation. I installed about 100 of these and believed they would be maintenance-free. So I don't replace bulbs as I did many years ago. But now I need to fix the electronics. I would have discarded and replaced a bunch of lights if not for your instruction.

Appreciate this video discussion. Maybe you can bypass the bad segment of LEDs by connecting + and - wires to connect the segment before to the segment after the bad one. Then all will burn except just few LEDs with minimal loss of illumination.

The control IC, usually uses a current sense resistor that you can change based on the datasheet to lower the current and you will need to find the datasheet for finding the right value.

Dear Taste The Code, can I connect an 12 watt driver to a 18 watt LED ceiling panel, hoping to dim the 18 watt LED panel to have the same brightness as the 12 watt panel? It is hard to find a 6-inch diameter 12 watt LED panel in Malaysia. Most sellers here sell only 6 inch 18 watt panels.

Hmmm it will probably work bit you will be pushing that driver to the max all the time and it might burn out. They are usually designed to pish certain current through the LEDs and they work in a certain range rather than a very specific wattage.

That is usually explained in the datasheet for the chip where there will be a formula to calculate the resistor required for the target current. But that is only if you are able to read the chip number and find a datasheet for it as often the numbers will be erased or datasheets are not available.

The driver chip will try to push a set amount of current through all LEDs so, it is better to just add a wire link. The downside is that there will be a dim spot in the panel, but it will work.

Hello, I have a led light that is controlled by a remote control. I ordered this from a distance and it seems to have been damaged in transit. After turning on the light, when I press with my hand where the drivers are located, the light changes color. (for example, if the white LEDs are on, they turn purple) Sometimes it recognizes the remote control and sometimes it doesn't. Which element do you think is damaged?
@TasteTheCode

Sounds like a bad connection or cracked PCB. You can try to inspect the PCB for damage or try to reflow some of the ICs.

Yes, each driver is rated for a set amount of power. Trying to draw more than that will damage it. You can test individual LEDs with a multimeter, but only if they are one LED per package. If they are more than you can't.

No need to test it when you can see that it is bulged. If it looks ok, then you can test it as a second step. A good capacitor should never be bulged!

Just remove one bad led. By string it by force and bridge the remaining pad w6a blob of solder and you are done. The panel will be running at a diferent voltage (3volt less) but the driver will take care of that.
@TasteTheCode

Yes, I'm aware of that and I've done this in the past with regular light bulbs. The problem here is that there are 5 LEDs in the string that don't light up and that will make a visible dark area on the panel that I don't think will look good.

@TasteTheCode

Yes, and flashing is a common sign that at least one of them is bad. It might be one of the LEDs as well but it is not that likely. They can be tested with a capacitance meter or a multimeter that has capacitance measurement. However, the cost of the capacitors is so low that it is worth changing them all just in case and trying it out. Make sure that the voltage rating is the same or more than what's already installed.

I would leave the legs of the first capacitor as long as possible. And not bent it over the board... Keep it as far as you can. To avoid the heat from the chip affecting it on the future
@TasteTheCode
@TasteTheCode Жыл бұрын
It is not the chip only as there is a lot of heat from the panel itself and the driver sits on top of it at all times. Having rhe capacitor away will definitely help but I don't think it will be too much of a difference.

In my country, Poland, similar lighting fixtures (lamps) are used, and most often the LED diodes burn out. The power supply is of poor quality, the lack of filters causes interference with FM radio reception.

I suggest replacing the caps with Rubycon or Nikkon Chemicon caps, of the highest termperature rating you can find. It'll be worth it in the long run. No-name chinese capacitors are the reason the lights failed in the first place.

I think you forgot to mention that whenever working with capacitors (regardless of whether good or bad ones) in AC circuits is to always discharge them for the safety reason as not to get an electric shock.. Capacitors do retain some energy even when removed from an AC line..

It is not uncommon to have chips with markings removed from the top so it is difficult to know what the exact chip is. If you can see a number, you can usually find the datasheet that will have its typical circuit in it. Most drivers are just a replica of the typical circuit diagram from the datasheet.

Guys, if you end up fixing these try installing lager caps and not smaller like in the video. and higher voltage if you can squeeze those in place. Lager size and voltage will give you a longer run. Say you had 25V 1000uF install 35V 1000uf. Cap body size is direct reference to how many hours it's designed to run for

Output voltage usually depends on the number of LEDs attached. For constant current drivers, it is the current that they regulate so you can have more (up to chip power limit) or less LEDs and it will still work. If everything else is OK on the board, you can either replace the chip if you find a replacement, or ditch the repair entirely as the price of these drivers in not really worth that much hustle.

Sometimes a failed driver unfortunately burn out some of the LEDs. I had bought some cheap driver panels from China to swap out with the bad. I may look at those bad drivers again and see if I can fix the component. I want to ask, can I use capacitors from old broken devices or do they go bad with age?
