DIY USB LED Light: Teardown & Assembly Guide
If you're interested in making your own DIY USB LED light, this article might give you some inspiration by showing you how to take one apart and reassemble it.
Even if you don't have the exact same LED light, you can follow this teardown process to build one yourself:
The LED light is a strip-type design, about a dozen centimeters long, with the model number YM-03D.
It runs on 5V 1A input and has a rated power of 2.8W (0.2W per light module × 4).
On the side, there's a micro USB port labeled with voltage specs.
There are no screws—here's what the inside looks like.
No clips either—the whole thing is held together by plastic pegs.
At the plug end, you'll find just a current-limiting resistor and a step-down diode.
The LED chips look like 3030s.
The light board is secured by heat-riveting with a plastic peg at the end.
Once you pry off the rivet, you'll notice the board doesn't even use an aluminum substrate.
Here's what it looks like with the diffuser removed.
Below are all the components laid out. You can use these parts or choose higher-quality ones to build your own custom LED light.
Here's what it looks like when powered on.
After testing, the actual power consumption is just 1.45W.
That's it.
