Powerful LED Flashlight



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.

Complete surprise. But I wonder who the author keeps reading for?
Damn, he would at least write what kind of bulbs to take. I once disassembled an online 8-watt bulb, so there even one LED does not light from a 3.7 volt battery, not to mention the complete circuit, which by the way diodes are connected in series. Of course, if you light this panel with the diodes, the flashlight really doesn’t turn out very bad, but I would not recommend repeating this design, since the information is clearly not enough in the description
Miserable rogue Indian product made with all conceivable and inconceivable errors.
I did not know that coins are a powerful radiator !!! Ahhhhh !!! Probably the whole secret is that they were glued with "hot glue" !!!!! )))))
Ashotaki? Shonitak?
It seemed to me that if we were to place something alien here, then at least worthy of repetition or approval. It turns out that this is not so. ((
