120v Dimmer Circuit

Light dimmers circuits and tutorials here is a 12 volt 2 amp lamp dimmer that can be used to dim a standard 25 watt automobile brake or backup bulb by controlling the duty cycle of a astable 555 timer oscillator.

120v dimmer circuit. The full wave phase control circuit below was found in a rca power circuits book from 1969. This basic design can handle light bulbs at power range of around 30w to few hundred watts depends on construction. 120 vac lamp dimmer this is diagram about 120 vac lamp dimmer you can learn online. The load is placed in series with the ac line and the four diodes provide.

This is an ac chopping circuit. The circuit is a basic model for light dimmer for 120v ac voltages. Considering that the capacitor need to pass current in both directions a modest diode is connected in parallel using the led to supply a path for the negative half.

More of the cycle makes the bulb brighter less is dimmer. The dim level sets where the ac waveform gets chopped on. When the wiper of the potentiometer is at the uppermost position the capacitor will charge quickly through both 1k resistor.
