This means that the LED driver has built in circuitry that can detect the AC being ‘chopped’ and dim the LED light accordingly. For a LED driver to work with a TRIAC type dimming switch it needs to be an AC Phase Cut Dimming type LED driver. These work by ‘chopping’ the AC mains going into the LED driver.
The dimmer switch you find in most Australian homes is either a leading-edge, or trailing-edge TRIAC type dimmer. You will need to check that your new light fitting is compatible with standard dimmer switches. If you are buying a new light fitting from a hardware store it will come complete with a LED driver.
It has to be especially designed to work with a dimming switch. In fact an LED driver is an electronic device. You won’t be able to use the existing transformer with a new LED light fitting.Īlthough the LED driver does a similar job to a transformer, it does it in a completely different way. It takes the incoming 240VAC power and converts it into the required DC power for your LED light fitting. The LED driver does a similar job to the transformer on your old light fitting. If you are replacing an old light fitting with an LED light for example, replacing a halogen downlight with an LED downlight, then you will need to make sure that the LED driver is dimmable. These should work with a standard wall plate dimmer. If you are simply replacing your incandescent or halogen globes with LED globes, then you need to make sure that the LED globes you buy are marked dimmable. The short answer is yes! But there are a few things that you need to be aware of.
