Addressable Light
Simply put, DALI is a two-way communication system that brings digital technology to lighting. According to the international communication standard, DALI’s primary function is to define commands that ballasts and LED drivers must recognize. The system allows individual LED drivers and ballasts to “speak” to the user, and the user can speak through a DALI controller, a computer with the appropriate software, or a building management system.
Key features of Digital Addressable Lighting Interface
- This is an open protocol and can be used by any manufacturer
- DALI2 ensures interoperability between manufacturers through mandatory certification procedures
- Installation is easy, the power line and control line can be placed together and no shield is required
- The wiring topology can be in the form of stars (hub and spokes), trees, lines, or any combination thereof
- Since the communication is not analogue and is digital, multiple devices can receive the exact same dimming value, which results in a very stable and accurate dimming performance
- All devices have unique addresses within the system, which opens up many options for versatile control.
