Fantastic Light Dimmer Circuit Diagram

We are using very minimal components in the circuit diagram.

Light dimmer circuit diagram. That is pretty much it and you can use the circuit for led. This circuit also works with other n channel mosfets as well. The basic circuit of light dimmer using triac is shown below and this circuit depends on phase control.

Lm358 is mainly made up of a package which contains two independent operational amplifiers of high gain. Assemble the circuit on a good quality pcb or common board. To overcome the interface problem r2 c3 are used.

Working of led lamp dimmer circuit. Led are available in many colors like red orange amber yellow green blue and white. It causes l1 is more brightest.

The capacitor c2 in the circuit below gets charge from the main supply. The irfz44n is an n channel enhancement type mosfet to it can deliver high output for a simple led dimmer. Ac light dimmer circuit using triac and diac update from the previous circuit operation of the circuit.

Then this charging voltage will control the works of triac. The circuit is based on the principle of power control using a triac the circuit and design are the same for fan or light the only difference is the output load to be varied that is fan or light. The variable resistor vr1 plays as a main controller in the light dimmer circuit.

Now a days led s are available in visible ultraviolet and infrared wavelengths and have high brightness. Just an irfz44n n channel mosfet and a potentiometer. Suppose that we adjust vr1 less c1 charges faster.
