DALI (Digital Addressable Lighting Interface) is a building automation system focused on lighting control. At the end of the 1990s, the DALI was defined as a protocol in a standard and developed into an international standard. This wired BUS is mainly used for larger lighting systems - commercial and public objects. Even emergency lighting can be controlled with this BUS. If no other applications are required apart from "light", the DALI offers all devices for this solution, including visualization. A control wire is required for the BUS. Wireless use of DALI is under development. In addition to lighting control, the status and error detection of luminaires are also an important function. Novel lighting functions include HCL (Human Centric Lighting) or Guided Light. The new version DALI-2 was launched in 2014. This is now used for device certification so that everything fits across manufacturers. The Digital Illumination Interface Alliance has been active for the international coordination of all DALI developments since October 2017.
