Indoor plants are a fairly common attribute of any home. The author of the following video showed how to make effective backlighting. To create it, accessible materials are used, most of which can be found at home. And the whole process will not take you much time.
To work, you will need:
* Red LED (660nm);
* Blue LED (465nm);
* Aluminum radiator 40x40 mm;
* Thermally conductive double-sided adhesive tape;
* Collapsible USB plug;
* An adapter with a USB socket - 5V 500 mA (necessarily not higher than 700 mA);
* Wire in soft insulation;
* Cable UTP-5e ("twisted pair");
* Wooden skewer;
* Food foil;
* Two plastic cups with a capacity of 0.5 l;
* Ethyl alcohol or vodka (for degreasing the surface).
Working process:
Before gluing the LEDs, the surface of the radiator must be thoroughly cleaned. For these purposes, you can use ethyl alcohol (or vodka).
Using a double-sided tape, we glue the LEDs to the radiator so that on each side there is a "plus" of one LED and a "minus" of the second. This will facilitate soldering.
Using a piece of cable core UTP-5e, passed through the radiator needles, we attach a wooden skewer. He will be the holder of the construction.
Solder the wire to the LEDs. Be sure to remember the core color for the "minus" or "plus" (both are better). Depending on the type of cable you are using, the colors may differ from the video used by the author. The wire should be attached to the skewer.
Solder the USB plug. It is at this step that the remembered colors of the wire strands are required. The joint must be made in accordance with the plug scheme.
Now the backlight should work, you can check.
We make a small lampshade with a reflector. We take one plastic cup, wrap it with food foil and put on the second.
To exit the heat, cut off the bottom of both cups. We put the lampshade on the main part of the structure.
The backlight is ready. Unfortunately, it applies only to small plants.
