Digital Illumination Interface Alliance Website:

The Digital Illumination Interface Alliance (DiiA) is an open, global consortium of lighting companies. Its main aim is to grow the market for lighting-control solutions based on IEC 62386, the international standard for digital addressable lighting interface (DALI) technology.

DiiA was established in response to industry requests for an independently-verified certification program that covers the functionality specified in the latest version of the IEC 62386 family of standards.

Product certification by DiiA brings the promise of significantly improved interoperability and additional functionality compared with the current DALI systems in the market.
