THE STREET lighting product ranges that can be Zhaga-D4i certified now includes DALI-based sensors and controllers with Zhaga connectors, as well as luminaires.
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.
Eligible devices include light-level or occupancy sensors, as well as control nodes that can communicate wirelessly with external networks.
This ecosystem of lighting products enables 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.
‘Bringing control devices into the Zhaga-D4i program will enable a certified ecosystem of interoperable products from multiple vendors, which will be welcomed by the lighting market,”; Paul Drosihn, DALI Alliance General Manager, told Lux.
‘With the Zhaga-D4i certification program, decision makers in outdoor road lighting can combine the long-lasting nature of the lighting infrastructure with the rapid changes in digital communication and sensor technology,’ said Dee Denteneer, Zhaga Secretary-General.
Zhaga-D4i luminaires have a powered Zhaga receptacle, which can accommodate a D4i-certified sensor or communication node with a corresponding Zhaga baseplate. Also, 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 can become platforms for the so-called Internet of Things, 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.
