DALI Lighting

Dali Digital Illumination Interface Solution

The DALI Alliance (also known as the Digital Illumination Interface Alliance, or DiiA) is the global industry organization for DALI lighting control.


DALI Alliance is open, global consortium of lighting companies, and they main aim is to grow the market for lighting-control solutions based on the standardized Digital Addressable Lighting Interface (DALI) protocol.
The DALI Alliance was established in response to industry requests for an independently-verified certification program, known as DALI-2, which is based on the latest version of the DALI protocol.


DALI-2 product certification by the DALI Alliance brings the promise of significantly-improved interoperability and additional functionality compared with the current DALI systems in the market. Products that have successfully completed the DALI-2 certification process are eligible to use the DALI-2 logo trademarks. Only certified products can carry the DALI-2 logo.


The DALI Alliance develops the test specifications that allow companies to test their products for compliance with DALI-2 requirements. These DALI-2 test specifications are derived by the DALI Alliance from the multi-part IEC 62386 standard or from DiiA specifications.


The DALI Alliance was formed by seven leading lighting companies: Erco, Helvar, Insta, Lutron, Osram, Philips Lighting and Tridonic. The DALI Alliance, also known as the Digital Illumination Interface Alliance, is a Partner Program of IEEE-ISTO, an international federation of leading industry groups and consortia dedicated to the advancement of standardized technologies for the benefit of industry.
