We keep on knowing thoroughly how our different regulations for LED lighting work. Today we will focus on the DALI regulation system.
The Dali control system is a protocol for regulating the luminous flux of a luminaire in a simple way. For this, it is necessary to install an extra two wire cable as a control bus, where we will send a digital signal through a voltage with a value between 16V and 17V. This signal will be responsible for managing the amount of light or the color transmitted to the luminaire.
It is based on the standard UNE-EN 62386 and is fully compatible with LED luminaires through power supplies or decoders.
With the Dali regulation control system, it is possible to regulate the light intensity, the turning on and off of the luminaire, as well as the color management of it.
It is important to know that on the control bus we will also have a voltage drop, as if it was any normal electrical circuit, so its distance has a lot to do with the section of the cable used. The maximum fall that it can support is 2V.
The Dali control system is a control communication protocol, its most important features are:
- It establishes a master bidirectional communication with the luminaires and allows the luminaries to send feedback or control information to the master’s control.
- It allows to discriminate between the luminaries, since it works by directions. The maximum number of luminaires is 64 and can be grouped into up to 16 groups.
Thanks to the Dali LED regulation system, we can control a multitude of LED luminaires, such as:
- Flexible LED strip for the most avant-garde installations.
- RGB downlights for indoor use.
- Ceiling panels for fluorescence replacement.
- Industrial Led Screen Lights and Projectors to ensure minimum lighting in work stations.
