This is circuit of soft light dimmer. This circuit uses the IGBT STGP10N50A and the TS555 timer as main components. Here is the circuit:

The timer is triggered on the zero crossing voltage pulse. The time constant determined by C5/R14+R15 that is used to determine the conduction angle. The T2 – T3 inhibits the power switch [...]

This circuit is similar with our previous dimmer circuit, but the gate control is full-wave rectified using diode bridge. This circuit can be used to replace electric switch for your incandescent lamp, brushed motor, soldering iron or heater. Here is the schematic diagram of the dimmer switch:

Please note that his dimmer switch can only work [...]

Light dimmer circuit is used to control the lamp for arbitrary brightness. This dimmer circuit work for incandescent lamp, not a fluorescent one.  The dimmer circuit here work for both 110V and 220V AC.  Here is the schematic diagram of the circuit:

Dimmer Wiring Diagram
The dimmer circuit is wired in series with the lamp, you can [...]
