How to make a powerful LED light bulb from an ordinary one

You can make a very powerful LED lamp for a headlight with your own hands from purchased ones. LEDs from Aliexpress. It is simply incredibly bright, and most importantly, it is repairable. A homemade light bulb is simply a salvation if it is not possible to buy a factory one for your headlight.
How to make a powerful LED light bulb from an ordinary one

Materials:


  • lamp base;
  • aluminum plate 3 mm;
  • printed circuit board;
  • LED SMD 3535 2 W 6 V – 16 pcs -
  • resistors SMD 2010 1.8 Ohm 3/4W – 12 pcs -

The process of making a high-power LED light bulb


For an LED lamp you will need a base from a regular light bulb.

Therefore, you need to break her flask and clear it of the entrails. 2 wires are soldered into the base.

Next you need to cut out an aluminum plate 35x15 mm. A longitudinal line is applied to it in the center, as well as markings 3 mm and 23 mm from one edge, and 4 mm from the opposite.

The conductor strips must be tinned.Flux is applied to the solder and laid out LEDs and resistors according to the diagram.

For soldering, the board is placed on the soleplate of the iron and heated. The second board is prepared in a similar way.

Next, the boards are lubricated with thermal paste and screwed on both sides to an aluminum plate.

All that remains is to insert them into the lamp base and screw it to it through the bushings. Then the power wires are soldered.

That's it, the light bulb is ready to be installed in the headlight.

    The heat dissipation is clearly insufficient for such an assembly. In addition, significant problems may arise with the calibration of the light spot. Well, the drivers from the meeting will hit the distant ones for being “super bright”

      Which one is far? These are running lights... just to write nonsense

    I made a similar collective farm to illuminate the room. Two pieces of tape 3 each LED 5730. I connected the MP1584 step-down switch via dc-dc and set the output to 11 volts. They shine like spotlights and without flickering.

    Where is the current stabilization?
