In this article, we will consider how to make a powerful LED flashlight using the LED panel from a faulty light bulb.
Tools and materials:
- Lithium-ion batteries;
-LED lamp;
-The wire;
-Switch;
-Connector;
-Plastic container;
-Nippers;
-Marker;
-Soldering iron;
-Knife;
-Heat-shrink tubing;
-Light-emitting diode;
diode 1N4007;
- Resistor 1 kOhm;
-Glue gun;
Step One: LED Panels
LED panels master "got" by disassembling light bulbs with faulty electronics.
Step Two: Case
For the case, the master took a plastic container. Cut a hole in the housing for installing the connector, button and charge indicator.
Step Three: Wiring
According to the scheme, makes installation.
Step Four: Heat Sink
Instead of a radiator, the master uses coins by gluing them to the back of the panel. According to the master, such a heat sink works well.
Step Five: Charging
Charges the flashlight.
Step Six: Testing
After charging, the master conducts night tests of the lamp.
According to the test results, the master decided to make several more lamps.
The entire process of manufacturing a flashlight can be seen in the video.
