Triac stands for triode for alternating current, is a generic trademark for a three terminal electronic component that conducts current in either direction when triggered. Its formal name is bidirectional triode thyristor or bilateral triode thyristor. Triac Dimmer is a type of dimmer designed for traditional AC lamps for example incandescent lamps and halogen lamps, and nowadays they are also widely used for dimming LED lights.
Since Triac dimming technology is now becoming very mature and reliable thanks to a long term of development, they are widely used for general illumination control such as residential lighting. Even if you use an old incandescent bulb, you can dim its brightness, let alone the latest LED lighting.
There are types of traditional controller for the Triac dimmer such as rotary knob switch or push button switch. The controller shall be connected to the Triac dimmer, AC input end of the dimmer shall be connected to AC mains. The AC output end of the dimmer shall be connected to the lamps or dimmable LED driver and LED Lighting Dimmers be connected to the LED lamps. Nowadays the controllers can be available in different types such as handheld remote, wall mounted full touch, rotary knob and push button etc.
DALI Dimmer is designed for LED lights, if you would like to dim your lighting with it, you have to figure out some questions first. What is the input type of the lights, AC or DC? If it is a AC input with dimmable driver built-in, the Triac dimmer can be directly connected to the LEDs. If it is DC input, you have to purchase an AC-DC dimmable driver first, then connect the Triac dimmer with the driver, and the driver with lamps. The DC LED lamps also have two types, constant current or constant voltage, then you have to purchase different types of dimmable driver for the lamps. Generally triac dimmer is suitable for AC high voltage LED lights. Using a Triac LED dimmer for residential lighting control is great for creating an energy efficient and smart home. It is one of the most reliable dimmer controller types and can offer stable and smooth dimming and switch control. Do not hesitate to dim your energy swallowing traditional lamps or new LED lights with a Indoor Led Dimmer.
