The “Digital Addressable Lighting Interface” is a cross-manufacturer interface that enables the control of electronic ballasts via digital control signals. Lights and other building technology components can be controlled individually or in groups, for example switched or dimmed.
Compared to the analog interface (1-10V) DALI can control individual operating devices due to their individual addressability. It is intended to guarantee the interchangeability of operating devices from different manufacturers in a lighting system.
Feedback from each individual device to the control unit is necessary in the event of a defect in the light source. DALI technology is only designed for lighting control. The can be addressed on one control line. It has very flexible application and installation options and is easy to use luminaires possible. A special DALI ECG is required for DALI control. This means that up to 64 DALI-compatible and individually dimmable
