Dimming systems are the ideal way to set the right lighting intensity, whatever the time or place. Discover which systems we work with at Delta Light here. Do you need installation advice or support on how to use the technology? We’ll gladly help you find the best solution to suit your needs.

The most commonly used dimming systems 

1-10V dimmers

This system makes for a perfect professional dimming method in the 0-100% light intensity range and allows you to preset lighting scenes when using home automation. It’s an analogue dimming technology in which a signal is given between 1 and 10 volts or potentiometer (100K linear). This requires two control wires between the power supply and the dimmer, a limited number of power supplies when using a potentiometer, and a main switch is needed to turn the lighting system on and off. A limited number of power supplies is allowed when using a potentiometer.

DALI dimmers

Digital Addressable Light Interface (DALI) is a universal standard for digital dimming systems and one of the most frequently used, regardless of the project scale. Unlike the analogue light settings, it allows you to dim each device separately, as each power supply gets an address. This way each device can be controlled independently from the other. The lamps can also return signals, making it flexible and economical to adjust the lighting. Integration into building management systems is quite simple. As a leading company in lighting and a member of DiiA, we embrace new technologies: the transition to DALI-2 was a logical next step. 

Dimming by switch dim (push button)

A low-cost installation that works with the push of a button, this provides perfect dimming in the 0 to 100% range. Things to keep in mind are the limited number of power supplies that can be dimmed with the same button ( max 5), this to prevent synchronisation problems and the need for 2 extra control wires.

Falling edge dimming on mains (FE)

There are two techniques for phase-dimming: trailing edge systems (also called falling edge) and leading edge systems. With this way of dimming, there’s an extra device, the dimmer, connected to the main input of the power supply. No extra control wires are needed and you can add it to your existing installation(s). This option allows for dimming between 30 and 100%, depending on the type of falling edge dimmer you’re using. A few things to consider are: blinking may happen when dimming to a minimum, and not all of them are compatible with LED. Furthermore it is recommended to use a dimmer of the type trailing edge. 

Wireless dimmers

Wireless dimmers offer extensive possibilities for smart buildings. CTRL Delta, our wireless dimming technology, allows you to integrate all kinds of electrical devices into a wireless network. As a result, lighting can be controlled via smartphones, tablets, smart watches, push buttons, switches or the Xpress control panel. Smart control can even be done via existing wall switches without changing the wiring.
