IEC 62386 standard

The international IEC 62386 standard

Overview of IEC 62386

DiiA specifications

Status of different Parts of IEC 62386

IEC 62386, the international standard for the Digital Addressable Lighting Interface, is published in multiple Parts by the International Electrotechnical Commission (IEC). Published Parts of IEC 62386 can be purchased from the IEC website.

The table below shows the status of different Parts of IEC 62386. Parts labelled as "in progress" are being developed by the IEC working group (WG11 of TC34) that is responsible for writing and maintaining IEC 62386. DiiA is an active participant in TC34 / WG11.

DALI-2 and the DALI Alliance

DALI-2 is the certification program operated by the DALI Alliance and based on the latest version of the DALI protocol. All new Parts of IEC 62386 are aligned with DALI-2. Some (but not all) older Parts will be updated to align with DALI-2.

The DALI Alliance develops DALI-2 Test Procedures, which enable companies to show compliance of their products with different Parts of DALI-2. Test Procedures are also developed from DiiA specifications.  

What's next? Creation of DALI-2 Test Procedures relies on input from DiiA members, and is influenced by member priorities and market demand. Our Timeline shows the planned priority for further DALI-2 certification development. >> Timeline

The following Table was updated in October 2021.

DiiA writes new specifications that define additional DALI features and functions, building on the IEC 62386 international standard.

DiiA specifications are freely available to both members and non-members of DiiA. >> Download here

DiiA intends to transfer its specifications to IEC, for publication as new Parts of IEC 62386.
