This dimmer for incandescent lamps was obtained from an American 1990s documentation. The circuit accepts triac-like loads that can be virtually any type. Triac must be fitted with a heat sink.
In this circuit the LED lights up when the input voltage drops below the value set in the trimpot. The...
