HANDMADE ENERGY SAVING LED LAMP (220V 50 LED) SCHEMATIC CIRCUIT DIAGRAM

In the end I made the led lamp 🙂 very often the breakdown of the apartment lamp in the region that caused the voltage around 230v at night 240v is going on occasionally sudden gellerda electronic circuit controlled economic CFLlamps are not based on the quality of the LED lamp because they often wanted to try to try.

The leds I use are the 5 th grade of the most name, but the performance is good at least for the apartment floors provided sufficient lighting FS-801 model sold in china circuit 38 led I changed a few materials to use 50 led

470nf with 50 led for the led voltage was around 2.8v in my hand though I would not use 1uf without pole 2 pcs 470nf 275v ac capacitor parallel was connected approximately 950nf was connected to the condenser parallel to the value of the connected resistance 1Mohm did 220v input 1 amp fuse added led to 3.2v per fell fell

The circuit I use

In fact, I have a formula for calculating the capacitor and resistor ( XC = 1 / 2pifC capacitance resistance, network frequency etc. ) but it exceeds me 🙂 I found the appropriate values.

Correcting the grid voltage and recharging the LEDs with passive elements is not very stable. There are many kinds of shape, shape lamps made of 20 LEDs, 30, LEDs, 100 LEDs, 150 LEDs

I installed the circuit in a very coarse manner I did not draw the printed circuit board led directly onto the perforated plaque. the yield is higher.

I like this led lighting business I would like to make a more advanced system (SMPS) in the future, at least I will evaluate the damaged lamp cases in my hands 🙂

The definition of capacitive reactance states that it is the opposition offered by a capacitor to the flow of ac current in the ac circuit. A capacitor opposes the changes in the potential difference or the voltage across its plates.
The formula for calculating the Capacitive Reactance, or impedance of a capacitor is: Capacitive reactance denoted as x sub c (XC), is equal to the constant one million (or 106) divided by the product of 2p ( or 6.28) times frequency times the capacitance. where: XC = Capacitive reactance measured in ohms.
