DALI stands for Digital Addressable Lighting Interface. It is an International Standard (IEC 62386) lighting control system providing a single interface for all Electronic Control Gears (light sources) and Electronic Control Devices (lighting controllers)
The DALI Standard enables dimmable ballasts, transformers, relay modules, emergency fittings and controllers from different manufacturers to be mixed and matched into a single control system. A DALI system provides designers, installers, building owners, facility managers and end-users a powerful and flexible digital lighting system with security of supply from many sources.
The DALI Standard is overseen by the AG-DALI activity group comprising engineers, manufacturers and institutions working in the field of digital lamp/luminaire control. DALI is effectively an enhancement on DSI control with the added advantages it has interoperability, status feedback and advanced control.
