Ac Dc Led Bulb Driver Circuit Diagram. But in this tutorial we will not use any dedicated driver ics but we will make a 2 5 watt ac led driver circuit. The fast adaption of led bulbs is already noticeable around us and the global led bulb market value has reached to around 5 4 billion in 2018.
Haseeb you ll need a 12v 2amp smps ac dc adapter for this you can connect the leds in series at the output of this adapter using a 0. We already made a transformerless led driver circuit previously but in that circuit we used a dedicated led driver ic like lnk304 to generate 13 6v 150ma of output current to power leds. These capacitors are connected line to line and are designed for high voltage ac circuits.
As shown in the circuit diagram below in its standard mode the resistor 240 ohms is a regular placement and the next resistor connected to it is the one which decides the voltage at the output of the ic.
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. But in this tutorial we will not use any dedicated driver ics but we will make a 2 5 watt ac led driver circuit. Ac led driver circuits are overly popular due to the advancement of high current white leds. Haseeb you ll need a 12v 2amp smps ac dc adapter for this you can connect the leds in series at the output of this adapter using a 0.
