MASTER LED BACKLIGHT

Send

Thanks to such a simple invention as LED backlighting, various things and objects can be decorated with bright lights. For example, casual shoes, roller or hockey skates, etc.
In order to perform the illumination, we need a soldering iron with solder and flux, a 12V or 8V battery (The higher the voltage, the brighter our backlight will shine), LED strip, several wires and a toggle switch.

A large number of LED strips are now available, in our case we use a waterproof tape. This tape is very securely attached due to the adhesive surface.

It is best to take flexible wires so that they can be bent without risking breaking. Both copper and aluminum will do. The cross section of the wires is selected based on the amount of current that will flow through them. And since our LEDs consume very little current, the cross section will fit the most minimal. However, for high-quality soldering, the wires must be tinned, and the insulation of too thin wires will melt very much, so it is better not to use the strings.
For convenient turning the backlight on and off, any compact switch is suitable, in our case we use a 3-pin toggle switch. The toggle switches are also selected by current, but here, I repeat, it is very small.
We proceed directly to the soldering process. The greatest difficulty is the process of soldering wires to the battery. In order to reliably and firmly solder them, first we clean the metal contacts on the plus and minus with fine sandpaper or an ordinary knife. After that, we solder the wiring to the plus and minus on the battery, having previously tinned them.

After this, it is necessary to do the same procedure with the toggle switch. We also clean the contacts a little and solder the wires to them, and we take one wire from the battery minus. As we can see, the circuit is almost ready, only the LED strip is missing.

There are 2 pins on the LED strip: + 12V and GND. We take the wiring from the plus of the battery and solder it to the + 12V pin on the LED strip. The remaining free wiring from the toggle switch pin is soldered to the GND pin on the LED strip. In the photo below I present what we should get.
