DALI is the acronym for "Digital Addressable Lighting Interface", it is an internationally public lighting control communication protocol that specifies the electronic ballast, control unit and various sensors. In other words, DALI is a protocol dedicated to lighting control. The currently established DALI Association covers nearly 120 companies in the lighting industry. Due to energy saving, emerging LED solutions and lighting control system,there is an increasing demand for the understanding of DALI, DALI has become more important than before, DALI dimming system, DALI dimming power supply, etc. will become the trend of dimming.

The dali system is basically composed of master control, sub-control, bus power and DALI dim driver. The characteristics of the DALI system are: a master-slave architecture can mount up to 64 slaves, and the master controls the slaves through the DALI bus and presses DALI Protocol for communication, each slave can be individually addressed, each slave can store 16 kinds of light scenes, the same slave can be grouped in one or more groups, and the maximum number of groups is 16. Is the DALI system very powerful? It seems to be a complex and powerful system, but there are no special requirements for wiring and installation wires, and no polarity requirements during installation. Only the main power line and the control line are required to be isolated, and the control line does not need to be shielded.
