The ABC's of Digital Addressable Lighting Interface (DALI)

DALI, or Digital Addressable Lighting Interface, is a digital communication protocol designed specifically for lighting systems.

An EMAIL INTERVIEW - with Stuart Berjansky & Ken Sinclair of AutomatedBuildings.com provides insight in the DALI lighting standard. This open standard was first established in Europe and has since been adopted in North America, where it is now being embraced in mainstream applications.


Berjansky: The introduction of DALI brings intelligence inside the ballast, transforming it to a "smart" device and ultimately allowing end users to set up virtually any lighting system configuration they desire. DALI's versatility makes it ideal for use with the most sophisticated Building Management Systems (BMS). It is especially suitable for facilities that wish to gain the benefits of automated energy conservation efforts through such techniques as daylight harvesting, load shedding, occupancy pattern tracking, and others. The DALI protocol also gives facility professionals the ability to easily track, archive, and evaluate their lighting investments.

Bringing maximum simplicity, flexibility, and freedom to facility professionals who wish to take full advantage of the remarkable potential offered by the DALI protocol, DALI is positioned to open many new possibilities for the automation of lighting control systems and the support of sustainable design.
