A large piece of metal or a piece of another solid and strong material like wood.
LEDS (is recomended between 50 and 70),
Step 1: The Large Piece
If you have for example 50 LEDS, you do 50 holes and after that cut the excess of the piece
where there are no holes
Step 2: Welding LEDS
parallel to the positive ones. You can do this by many series of six or seven LEDS and weld
the LEDS with a constant distance between each one.
Step 3: Putting the LEDS
made of metal. Copper wire cannot touch the metal because it causes a short circuit.)
The head of the LEDS have to show to the other side to iluminate. Also you can use silicone
to paste the LEDS to the piece, so the LEDS wont fall.
Step 4: Connecting
We have to weld the copper wires to connect all the series in parallel.
Finally with these steps passed we are ready to test our LED luminaire.
It is very easy and very useful.
