220 volt LED light

Hello.
We didn’t live off and nothing foreshadowed troubles, but with a sharp rise in price of electricity, I thought about saving electricity and decided to start small, to make LED lamps with minimal investment of money.

The scheme of the LED lamp is quite simple and does not require higher education for its assembly, any novice radio amateur will be able to assemble it.

Pretty simple scheme, now a little about the scheme.
The capacitor C1 is selected directly from the current of the LEDs, I have 18 smd5050 LEDs in it, in one LED case there are three crystals, for a total of 54 LEDs connected in series.
One LED consumes 20 mA. the LEDs are connected in series, the current does not change, the capacitor is set to 0.47 microfarad 400 volts, and a current consumption of 17 mA is obtained, there is no need for more, let the small margin be better.
Next is a diode bridge that protects the LEDs from reverse voltage, I put a diode bridge DB107S 1A 1000 volts, such a bridge is quite enough for this circuit.
Next we have a 100 Ohm resistor, and no matter how many LEDs are 1 or 10, the resistance does not change, but there is one thing, only the power of the resistor changes depending on the power of the LED.
I put a 0.125 watt resistor on my 20 mile ampered LEDs, but when I put on a half-watt LED and consumed 180 mA, I put a 0.5 watt resistor.
Next we have a C2 capacitor, it protects our LEDs from surges in the network, I myself took the capacitor with a 4.7 microfarad 400 volt from an economy bulb.
That's actually the whole scheme, now go to the PCB.



The printed circuit board is made on two-sided foiled fiberglass, capacitor C2 is not specified because I solder it parallel to the LEDs, and its legs serve as jumpers on the second side of the printed circuit board.
This way I saved space on the board.



That actually turned out such an LED lamp for the home in a couple of hours, and you can watch a full review of the LED lamp in this video clip. Thank you all, see you soon.
