LED Camping Light

This is a straightforward LED camping light. It has a built-in lithium battery, consisting of two 18650 cells connected in parallel, along with a protection and charging module for the battery. A single 3-watt LED serves as the light source, which requires some form of cooling to prevent overheating. To address this issue, I employed a salvaged heat sink from an old PC motherboard's north bridge. Additionally, a 1-ohm resistor is connected in series with the LED to serve as a regulator. To enhance the lamp's brightness, a plastic mirror is integrated into the cap piece; however, any reflective material such as foil tape or something similar can be used instead.
