Trailing-edge dimmers are more sophisticated than leading-edge dimmers. They provide a much smoother dimming control, absent of any buzzing noise, and is ideal for use in most premises. A trailing-edge dimmer has a lower minimum load than leading-edge dimmers, making it a better choice for dimming modestly sized low-powered lighting circuits.
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.
9/29/2020 · Together, leading and trailing edge dimming technologies are referred to as phase cutting dimmers and they are named after the part of the AC wave that they cut off to dim the lighting. Dimmer switches using leading edge technology cut off the front edge of the half cycle of each AC wave, whereas trailing edge dimmers cut off the second half of each half cycle.
WHICH DIMMER IS RIGHT FOR YOU? Leading edge dimmers usually cost less than trailing edge dimmers, causing them to be more popular more often recommended to consumers. But trailing edge dimmers are well-known for the exhibition of EMI that has been lowered, giving them preference in certain markets. Anyone who has gone to Europe should be familiar with them. Also, noise-sensitive.
Fully compatible with resistive or capacitive loads, which shorten the A/C cycle, modern Trailing – Edge dimmers effectively reduce the 240V mains supply to a 12 or 24V load which is perfect for dimming LED lights and bulbs. Replacing your existing leading – edge dimmer switches with up-to-date trailing – edge units is quite a simple procedure.

Trailing edge dimmers are now the more popular of the two types. They have several advantages over leading edge dimmers including smoother control, soft start and silent running when in operation. Both types of dimmer can work with dimmable LEDs however due to its advantages, trailing edge is the preferred and as such LED manufacturers have designed their retrofit lamps to work best with this type.
8/30/2013 · Figure 1: Trailing edge. Source: Shuttle Lighting. Leading edge dimmers (aka “triac dimmers” or “incandescent dimmers”): The electrical current (sinusoidal signal) is turned off at the front of the AC input waveform immediately after the zero crossing; Traditionally used for incandescent lamps or magnetic low voltage transformers, 3/22/2019 · Trailing Edge. These more modern dimmers have many benefits over the leading edge type. These improvements include smoother dimming with less buzzing and interference. Trailing edge dimmers have a much lower minimum load than the leading edge, making them far more suitable for powering LEDs. Using Trailing Edge Dimmers with LEDs, 10/18/2011 · Trailing Edge Triac.
