Automatic Light Dimmer Circuit. This is an automatic light dimmer circuit. You do not need to dim the lights by yourself. It is so very convenient because we use the LDR to detect external light. To control the Triac and the brightness of the lamp next.

This circuit is a part of an automatic light dimmer circuit published in Elektor Electronics Magazine July/August 1998 issue pages 75-76. Professional voltage controlled dimmers. Remotely controlled light dimmers in theatrical and architechtural applications typically use 0-10V control signal for controlling the lamp brightness.

How Dimmer Switches Work. ... In the last section, we saw that a dimmer switch rapidly turns a light circuit on and off to reduce the energy flowing to a light switch. The central element in this switching circuit is a triode alternating current switch, or triac.

In the electrical schematic shown, a typical silicon-controlled rectifier (SCR) based light dimmer dims the light through phase-angle control. This unit is wired in series with the load. Diodes (D2, D3, D4 and D5) form a bridge, which generates pulsed DC. R1 and C1 form a circuit with a time constant.

The basic circuit of light dimmer using TRIAC is shown below and this circuit depends on phase control. The variable resistor VR1 plays as a main controller in the light dimmer circuit. The capacitor ‘C2’ in the circuit below gets charge from the main supply.

A trailing edge dimmer is a considerably more complex circuit. The simple circuitry that is common with leading edge types can no longer be used, because most TRIACs cannot be turned off. Gate turn-off (GTO) TRIACs exist, but are far more expensive and less common in the relatively small sizes needed for lighting.
