There are three key methods of dimming LED: mains, constant current (CC) and constant voltage (CV) .
- Mains dimmers are used with LED replacement bulbs.
- CC dimmers put out a controlled current, which means that the fixture does not need electronics for current control of the LED. This style of dimming is used for higher power LED products.
- CV dimmers put out a constant voltage and the current control is done by the LED fixture. This type of dimming tends to be used for the lower power LED products such flexible tape.
It is important to choose the correct technology of dimmer as an incorrect choice will most likely damage the fixture. Below is a summary of the dimmers offered by Artistic Licence:
