TRIAC dimming controls act as a high-speed switch and are used to control the amount of electrical energy passing to a bulb. A ‘trigger’ dictates what point the device starts to conduct the electricity, essentially “chopping up” the voltage waveform, stopping the voltage from being supplied at full load.

The quicker the switch reacts the more power is let through and the later it reacts, the less power, resulting in a dimming of the bulb. This is very similar to more common Thyristor dimmers, however TRIAC dimming is less likely to produce “half wave” on failure or Hz flicker and therefore the lifespan of the LED’s are not as greatly reduced as they are with Thyristor dimmers.
