Zhaga and DiiA Unveil Joint Zhaga-D4i Certification Program

The Zhaga Consortium (Zhaga) and the Digital Illumination Interface Alliance (DiiA) have unveiled their joint Zhaga-D4i certification program, indicating plug-and-play interoperability of luminaires, sensors and communication nodes.

Combining the expertise in the two organizations, the Zhaga-D4i certification program will enable smart, future-proof LED luminaires with IoT connectivity. Initially, the focus is on outdoor lighting, but indoor solutions are also in development.

Zhaga-D4i certification will be available for outdoor LED luminaires that have a Zhaga Book 18 socket and contain D4i-certified LED drivers. Compatible sensors and wireless communication nodes with a Zhaga connector will also be eligible for Zhaga-D4i certification.

Expected to launch in the third quarter of 2019, Zhaga-D4i certification will be made available by the Zhaga Consortium to its Regular and Associate members.

All Zhaga-D4i certified products will be eligible to carry both the Zhaga and D4i logos, to give a clear indication of interoperability. The Zhaga logo and the D4i logo are trademarks of Zhaga and DiiA, respectively. All certified Zhaga-D4i products will be listed on the Zhaga website.

"The use of the Zhaga and D4i logos together on luminaires and nodes will provide clarity and confidence in multi-vendor product interoperability," said Paul Drosihn, DiiA General Manager.

Zhaga-D4i certification is based on complementary specifications from Zhaga and DiiA, which together standardize the interface between LED luminaires and sensors and/or communication nodes. The specifications cover all the critical features including mechanical fit, digital communication, data reporting and power requirements, ensuring plug-and-play interoperability of luminaires and nodes. Zhaga-D4i combines the Zhaga Book 18 connector system (http://bit.ly/2J43PTN) with DiiA's D4i specifications for intra-luminaire DALI (www.dali2.org/d4i).

"Based on open standards, the Zhaga-D4i certification program will result in value creation and reduced complexity for outdoor lighting and Smart City projects," said Dee Denteneer, Zhaga Secretary-General.

More information on the Zhaga-D4i certification program is available in an article in the May/June issue of LED Professional Review.
The article excerpt from the magazine is available on the Zhaga and DiiA websites.

About DiiA:

The Digital Illumination Interface Alliance (DiiA) is an open, global consortium of lighting companies that aims to grow the market for lighting-control solutions based on Digital Addressable Lighting Interface (DALI) technology. DiiA is driving the adoption of DALI-2, the latest version of the internationally-standardized DALI protocol. DALI-2 includes more product types, more features, clearer specifications and increased testing. DiiA operates the DALI‑2 certification program, bringing the promise of significantly-improved interoperability compared with current DALI systems in the market. DiiA develops test specifications for DALI-2 product compliance testing, and also creates new specifications for additional DALI-2 features and functions.
