D4i sensors and controllers for smart, IoT-ready luminaires

October 22, 2020

The DALI Alliance (DiiA) is now offering D4i certification of DALI-based control devices that are designed for mounting on LED luminaires.

Eligible devices include light-level or occupancy sensors, as well as control nodes that can communicate wirelessly with external networks.

D4i is the DALI standard for intelligent, IoT-ready luminaires. By taking care of control and power requirements, D4i makes it much easier to mount sensors and communication devices on luminaires.

In addition, intelligent D4i LED drivers inside the luminaire have the capability to store and report a wide range of luminaire, energy and diagnostics data in a standardized format.

The requirements for luminaire-mounted control devices are defined in the DALI Part 351 specification, created by the DALI Alliance, which builds on the IEC 62386 international standard. Qualifying D4i control devices implement Part 351 as well as meeting the requirements for DALI-2 certification.

More information can be found in the Part 351 specification, which is freely available on the DALI Alliance website. 

D4i certification is open to all DALI Alliance members, and all D4i-certified products are listed in our online product database.
