#Loupe with Led Light
The circuit is not complicated, only 3 LEDs (SMD 3528) are connected in series with a 120 ohm resistor (SMD 0805). These segments are included in a parallel circuit with 12V power. Only 10 segments. As a result, we get excellent light without overheating. The brightness will be 240 lumens, which completely covers the task of lighting from the magnifier. The PCB can be ordered here: https://jlcpcb.com/ only $2.00 In the near future, I am also going to order PCB, and later I will post gerber files. In the meantime, you need to print the case ...
Oh yes! There are many finished products of this kind on the market, and you can buy them. But I do not like them, so I made my own version.
