To do this it needs to have "AC Phase Cut Dimming". The LED driver needs to have been designed to specifically work with this type of dimmer switch. These type of dimmers chop the 240VAC input. The standard wall plate dimmer you see in most homes and offices is either a leading-edge, or trailing-edge dimmer. In many cases you cannot use a standard wall plate dimmer to dim LED lights. There are one or two possible reasons why your LED lights flickering when you dim them. What if your LED lights flicker when you dim them? If you use the wrong type of LED driver for your light fitting then the LED light will flicker when there are fluctuations in the incoming AC power at the wall socket, as there often is. You will need to check at what power this voltage needs to be delivered at. It does this by adjusting the output current accordingly. For example on the LED driver you will see something printed like ‘Output: 12V’.Ī constant voltage LED driver will ensure that the voltage supplied to the LED light fitting remains constant, regardless of any fluctuations at the power point. This will have an output given as voltage (V).
