These in light fixtures generate power control with 1-10V dimming. The dimmer cuts part of the mains voltage sinusoidal waveform to a greater or lesser extent in order to dim luminous flux even from 1% to 100% (this value depends on dimmer and driver).ĭepending on how the driver makes the mains voltage cut, it is possible to distinguish between two types of dimming:

It involves connecting a dimmer in series between one of the mains wire and the equipment. This type of control is accomplished without any need for an additional control wire. But dimmer, driver and LED-module must be compatible with each other.

Leading & trailing edge dimmingīefore LEDs, we used to dim halogen lamps with wall dimmers. Phase dimming systems dim the lights by altering the supply voltage.

If your fixtures are non-dimmable, then you can only have on/off – function.Īnalogue dimming covers all dimming systems that don’t transform the dimming signal into bits and controls the lighting in analogue manner.

Are your fixtures dimmable? If yes, what is the dimming method which works together with your fixtures.

When you want to control lighting, you have to know some basic issues of your lighting fixtures: I am grouping the dimming methods in two main groups: analogue and digital. The goal is to give you the basic understanding of the dimming methods available at moment. What are the possibilities and what dimming should you look from a LED driver? I’m going to answer these questions in this blog post by going through the different systems. You can use several different dimming options to dim LED Lighting.
