Powerful LED Downlight

Electronics / LEDs

Hello everybody. How to make a powerful and at the same time economical LED lamp? Yes, very simple.

For this you need:
1- ready board for soldering LEDs
2- LEDs 8 mm

We take a board for soldering.


LEDs 15 pieces

We solder the LEDs on the board


We don’t cut the legs, they act as a heat sink, we connect all the short legs and all the long legs in parallel, after which we connect all the short and all long ones with a thicker wire.

We connect the power supply and see what happened.

We connect directly to the assembly of lithium batteries with a capacity of 15,000 mAh - how long will this assembly shine without recharging?

It remains to find a suitable housing for the lamp.

How simple it is for you. How to charge the batteries? It is not necessary ?

I can, the rest cannot .. for 4 years I have been shining 3 lamps with 6 LEDs from the solar panel. 1 watt LEDs on the radiator are connected in series of three pieces, powered directly from the batteries when the 14 volt charge burns brightly .. when the sun does not burn dim , and there is not a single resistor .. I can show in the next homemade.

“They told the world how many times” that LEDs cannot be connected either in parallel or in series without extinguishing resistors for each LED.
