DALI stands for Digital Addressable Lighting Interface. It is a 2-way communications protocol that is used to provide control over, and communication between, the components in a lighting system. DALI originated in the late 1990s and was defined in IEC60929. Since then it has been substantially modified. The current (2020) version of DALI is called DALI-2 and this is defined in IEC62386.
Features of DALI
- It is an open protocol – any manufacturer can use it.
- With DALI-2 interoperability between manufacturers is guaranteed by mandatory certification procedures.
- Installation is simple. Power and control lines can be laid together and no shielding is required.
- The wiring topology can be in the form of a star (hub & spoke), a tree or a line, or any combination of these.
- Communication is digital, not analogue, so the exact same dimming values can be received by multiple devices resulting in very stable and precise dimming performance.
- All devices have their own unique address in the system opening a very wide range of possibilities for flexible control.
