About the Digitial Illumination Interface Alliance

Welcome to the DiiA

The Digital Illumination Interface Alliance (DiiA) is the global industry alliance for DALI lighting control.

We are an open, global consortium of lighting companies, and our 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 DALI-2, the latest version of the IEC 62386 family of standards.

DALI-2 product certification by DiiA brings the promise of significantly-improved interoperability and additional functionality compared with the current DALI systems in the market.

Certified DALI-2 products are eligible to carry the DALI-2 Certification Mark, issued by DiiA, which signifies interoperability on a global basis according to IEC 62386. Only certified products can carry the DALI-2 Mark, and only DiiA members can certify their products. 

>> All DALI-2 products are listed in the Product Database

DiiA develops the test sequences that allow companies to test their products according to the requirements of the DALI standard. 

DiiA members also work together to develop new DALI features and functions beyond the current IEC 62386.

DiiA was formed by seven leading lighting companies: Erco, Helvar, Insta, Lutron, Osram, Philips Lighting and Tridonic.
