Triac dimmer switch is one of the most mature dimming technologies that are suitable for traditional incandescent lamps and halogen lamps. And gradually it is developed to be suitable for LED lamps.

With a triac LED dimmer switch, you can dim LED downlights, LED spot lamps etc. Of course if the LED lamp is designed with built-in dimmable driver, the triac dimmer can be directly connected to it, otherwise you need a external dimmable driver. Triac dimmer switch is very popular in the market and features many advantages.

Firstly, the Triac dimmer switch is designed with 100-240VAC wide input and output which can be suitable for most countries all over the world, it can be compatible with both AC and DC LED lamps. It can be directly connected with dimmable LED lamps or dimmable LED drivers. It comes with full isolated design, which ensures high safety and reliability.

Secondly, it can be triac dimmable and mosfet dimmable. Mosfet dimming enables PWM control which ensure smooth and fast brightness adjustment without any flickering.

Thirdly, it is switchable between leading edge dimming and trailing edge dimming. This is a very important feature that allows users to choose the dimming velocity. Phase-cut dimmers, either leading-edge or trailing-edge, make up the bulk of the dimmer market. After the input voltage rises following the zero crossing, leading edge dimmers inhibit for a period of time, controlling energy transferred to the lamp load and hence output brightness. Trailing-edge dimmers also regulate output by inhibiting for a period of time, however this is referenced to the negative going edge of the half-cycle. Leading-edge dimmers are typically lower cost and so are more widely used whereas trailing–edge dimmers exhibit lower EMI and are preferred in some markets (notably Europe) and noise sensitive environments. That-being-said, it is unlikely that the average consumer will know whether their fixture is controlled by a leading-edge or a trailing-edge dimmer, and so it is important that LED replacement bulbs work with both types.

The LED dimmer switch needs a control unit to send control signal, if you would like a wireless one, an RF remote is perfect, accordingly the Triac dimmer shall have built-in RF receive module. If you would like a traditional control unit, a DMX512 control unit can be a great choice, and the dimmer should have DMX512 module inside.
