what is dali

DALI stands for Digital Addressable Lighting Interface. It is a two-way communication protocol used to provide control over, and communication between, the components in a lighting system. DALI enables the easy installation of robust, scalable, and flexible lighting networks. It was originally developed to allow digital control, configuration, and querying of fluorescent ballasts, replacing the simple, one-way, broadcast-like operation of 0/1-10V analog control. With DALI, the broadcast option is also available, and with simple configuration, each DALI device can be assigned a separate address, allowing digital control of individual devices. Furthermore, the DALI devices can also be programmed to operate in groups, providing excellent flexibility since the lighting systems can be reconfigured by software reprogramming, without the need to change the wiring. Different lighting functions and moods can be achieved in different rooms or areas of a building, and then easily adjusted and optimized. The digital nature of DALI allows two-way communication. DALI is an open protocol, meaning it is a common platform that can be adopted by all lighting equipment manufacturers.
