Zhaga and DiiA joint certification program launches

February 01, 2019 // By Julien Happich
The Zhaga Consortium (Zhaga) and the Digital Illumination Interface Alliance (DiiA) are developing a joint certification program for interoperable luminaires and components, which enables intelligent, future-proof LED luminaires with IoT connectivity.

The certification program will be based on complementary specifications from Zhaga and DiiA, which together define the smart luminaire interface. This interface simplifies the addition of communication/sensor nodes to LED luminaires with plug-and play interoperability. Initially the focus is on outdoor lighting, but indoor solutions will also be developed.

The joint certification program will include outdoor LED luminaires, as well as components such as drivers, sensors and communication nodes. A certification mark will clearly indicate interoperability. Further details will be announced in the second quarter of 2019.  

“Our joint certification program will provide the entire value chain with confidence in multi-vendor product interoperability,” commented Ruud van Bokhorst, General Manager of DiiA. “It will reduce complexity and add value for luminaire makers and commercial end-users, allowing the upgrading of the digital functions of smart luminaires.”

The smart luminaire interface is based on the DALI protocol for intra-luminaire communication, including the recently-published DiiA specifications for integrated DALI power supplies, and data storage/retrieval for asset management, energy reporting and diagnostics. These specifications will be referred to in the upcoming Zhaga Book 18 ed. 2.0 which also defines the mechanical connectivity interface and conditions for interoperability.
