The joint Zhaga-D4i certification program from the DALI Alliance and the Zhaga Consortium has already qualified a number of Zhaga-D4i Book 18 outdoor luminaires with Zhaga receptacles and D4i components. Now certified D4i control devices with Zhaga connectors can also be submitted for Zhaga-D4i certification, according to a recent statement by Zhaga. Eligible devices include light-level or occupancy sensors, as well as control nodes that can communicate wirelessly with external networks, enabling smart, future-proof LED luminaires with IoT connectivity.
Certified Zhaga-D4i products can carry the dual logos of Zhaga and D4i which together indicate plug-and-play interoperability of sensors, communication nodes, and luminaires. With this new Zhaga-D4i certification program, control solutions with interoperable products from multiple vendors can be constructed, and designers and owners of outdoor road lighting can combine their lighting with digital communication and sensors.
Zhaga-D4i luminaires have a powered Zhaga receptacle, which can accommodate a D4i-certified sensor or communication node with a corresponding Zhaga baseplate. Additionally, Zhaga-D4i luminaires use LED drivers meeting the D4i requirements, including the availability of DALI luminaire, energy and diagnostics data.
D4i enables DALI in intelligent, IoT-ready luminaires. By taking care of control and power requirements, D4i makes it easier to mount sensors and communication devices on luminaires.
Smart Zhaga-D4i luminaires serve as an IoT platform, capable of gathering information from on-board D4i sensors and providing data via DALI for performance monitoring, asset management, predictive maintenance, and many other tasks. Communication and data exchange with an external network can take place using a D4i control device with wireless communication capabilities.
