DiiA specifications

Data and Power-Supply specifications

DiiA has finalized a set of five new specifications, based on the DALI lighting-control protocol, that address the market need for intelligent lighting fixtures with sensing and communication capabilities and IoT connectivity.

The specifications enable smart DALI drivers that can report data, supporting DALI in the IoT era, and can also simplify the addition of sensors and communication nodes to luminaires via an intra-luminaire DALI bus.

>> DALI specifications from DiiA enable intelligent, connected LED luminaires


The five DiiA specifications listed below were finalized in August 2018, and are now available for download by DiiA members and non-members.

Currently, the specifications are NOT part of IEC 62386. 

DiiA will create test sequences for the new specifications, enabling their incorporation into the DALI-2 certification program.


DiiA specification

Power-supply specifications
(Define how power is supplied
to other DALI devices inside
a luminaire)
DALI Part 250 – Integrated Bus Power Supply
AUX Power Supply
- This specification does not involve DALI memory banks
Data specifications
(Define how data is stored,
accessed and reported)
DALI Part 251 – Memory Bank 1 Extension
- Covers luminaire-related data for asset management
DALI Part 252 – Energy Reporting
DALI Part 253 – Diagnostics & Maintenance




Please view our presentation to learn more about our new DALI specifications.

The following images show two possible implementations that benefit from the use of the new DALI specifications from DiiA. See our presentation for more details. 

Supporting DALI in the IoT era

The specifications support smart, connected luminaires that can report operational, diagnostic and inventory data.

Enabling DALI in standalone luminaires

The specifications simplify the addition of sensors and communication nodes to luminaires, via an intra-luminaire DALI bus.
