Leading Edge vs. Trailing Edge Dimming

To continue last week's topic of dimming, today we will discuss the difference between Leading Edge Dimming and Trailing Edge Dimming.

Leading Edge Dimming (TRIAC dimming) utilizes a current that is turned off as the AC waveform begins, right after it crosses zero. Leading Edge Dimming is typically used with incandescent bulbs, and produces a rush of voltage every half cycle, resulting in a rush of current to the light source.

Trailing Edge Dimming (electronic dimming) utilizes a current that is turned off as the AC waveform ends, right before it crosses zero. This type of dimming is typically used with electronic drivers, and does not result in a rush of voltage (and in turn, a rush of current) to the light source.
