DALI-2 Certification Helps Interoperability and Sustainable Lighting

DALI-2 certification builds confidence within the interoperability of DALI-based gadgets from completely different producers. As a standardized platform, DALI-2 mitigates issues round proprietary applied sciences and vendor lock-in, and permits future-proof luminaire and system designs for sustainable lighting.

Pushed by the DALI Alliance and constructing on the necessities of the worldwide IEC 62386 normal, DALI-2 certification requires rigorous product testing. The check outcomes are independently verified by the DALI Alliance. In distinction, DALI version-1 testing was much less detailed and relied on self-declaration, with out requiring third-party verification of check outcomes.

DALI-2 certification is now out there for all management gear sorts in widespread use, together with these for color management and self-contained emergency lighting. DALI-2 additionally features a broad vary of extra options akin to storage and reporting of luminaire, power and diagnostics information.

“DALI-2 certification has matured sufficiently that we now not see the necessity to provide a registration scheme for DALI version-1 management gear,” stated Paul Drosihn, DALI Alliance Basic Supervisor. “We encourage all customers to search for the DALI-2 or D4i logos, which affirm that the product is licensed by the DALI Alliance and is totally compliant with the related specs.”

DALI version-1 registration was solely out there for management gear, whereas DALI-2 certification additionally contains bus energy provides, and management gadgets akin to utility controllers, sensors and different enter gadgets. DALI-2 certification has established an ecosystem of interoperable merchandise, that are all listed within the on-line Product Database. This comprises over 2,300 DALI-2 merchandise, together with greater than 1,800 DALI-2 management gear, together with over 1,600 DALI version-1 management gear. The DALI version-1 merchandise will stay within the database, and trademark use will proceed to be allowed.

In addition to working the extremely profitable DALI-2 and D4i certification applications, the DALI Alliance is growing DALI+ certification for DALI gadgets working over wi-fi and IP-based networks, and is collaborating with the Zhaga Consortium to supply Zhaga-D4i certification for luminaires and management gadgets.

The DALI Alliance (often known as the Digital Illumination Interface Alliance or DiiA) is an open, international consortium of lighting corporations that drives the expansion of lighting-control options based mostly on internationally standardized Digital Addressable Lighting Interface (DALI) expertise. The group operates the DALI-2 and D4i certification applications to spice up ranges of cross-vendor interoperability. As lighting continues to evolve and converge with the IoT, the DALI Alliance can be driving the standardization of wi-fi and IP-based connectivity options. For extra data, go to
