Mike miskin explains the role of the capacitor in the circuit.
Hi friends my channel technical study.
Led i e light emitting diode is a special kind of diode that emits energy in the visible band of the electromagnetic spectrum.
The input mains 220v or 120v ac is half wave repaired by d1 and c1.
These capacitors are connected line to line and are designed for high voltage ac circuits.
We are a widely acclaimed manufacturer supplier trader and exporter of a wide series of led bulb driver.

A typical c 3 led device combines 2 or more leds die in multiples of 2 or more to use both halves of the ac cycle efficiently with a capacitor.
Frnd es video me driver circuit ki faults ko bina bulb khole aap jaan sakte hai wo bhi 2 second me aur kya kharab ho sakta hai wo bhi jaan jayenge.
C1 together with the inductor l0 and c2 make up a pie filter network for cacelling emi disturbenaces.
Ac led drivers are typically used with bulbs that already contain an internal driver that converts the current from ac to dc so an ac led driver s job is to register the low wattage of leds and step down the voltage to meet the bulb s voltage requirements usually 12 or 24 volts.
230v led driver circuit principle.
A challenge in designing these led bulbs is that led light as we know works on dc voltage and the mains power supply is ac hence we need to design a led driver circuit that could convert the ac mains.
Much like the resistor in the dc circuit the capacitor drops the voltage and delivers the required current to the leds based on the voltage and frequency input to the capacitor from.
It is used as an optoelectronic device.
However it conducts in forward bias the same as the p n junction diode.
