Triac

Principle: The principle of dimming is based on adjusting the true RMS (Root Mean Square) power/effective power by controlling the firing angle of a solid state switching device called a triac at the zero crossover of the sinusoidal waveform at both the positive and negative half wave cycles. ❋ Unknown (2010)
