Zhaga-D4i interoperability is important for smart city lighting

Plug-and-play interoperability between luminaires and sensors and communication modules is an essential requirement for Smart City lighting.

This has been the primary motivation for the collaboration between the Zhaga Consortium and the Digital Illumination Interface Alliance (DiiA) over the upcoming Zhaga-D4i specifications. Both organisations are therefore proud to announce that booth C17 at the LED professional Symposium in Bregenz will showcase the world’s first Zhaga-D4i interoperability demonstration.

Zhaga and DiiA have standardized the interface between outdoor LED luminaires and sensors and communication modules. The initial focus has been on outdoor lighting, with indoor applications being a work in progress.

The standardization effort brings together complementary specifications from the two organizations, which cover mechanical fit, digital communication and power requirements. This ensures plug-and-play interoperability of the luminaires and modules, backed by the Zhaga-D4i certification program.

Zhaga-D4i certification allows qualifying luminaires and modules to carry the dual Zhaga and D4i logos. This provides a clear indication of plug-and-play interoperability, which is a strong benefit for specifiers, purchasers, installers and end users.

Zhaga and DiiA expect to launch their joint Zhaga-D4i certification program in the fourth quarter of 2019.

The Zhaga booth C17 at the LED professional Symposium in Bregenz will host a functional set-up of streetlighting luminaires. The demonstration will show plug-and-play interoperability between a number of products being designed to meet the Zhaga-D4i specifications, and involve luminaires, sensors, communication modules, drivers and receptacles from companies such as BJB, Legrand, Osram, Schréder, Signify and TE Connectivity.
