Sensors and controllers for smart IoT-ready luminaires

28-10-2020 | DALI Alliance | Lighting Technologies

The DALI Alliance is now offering D4i certification of DALI-based control devices that are created for mounting on LED luminaires. Suitable devices comprise light-level or occupancy sensors, as well as control nodes that are able to communicate wirelessly with external networks.


By taking care of control and power demands, D4i makes it far easier to mount sensors and communication devices on luminaires. Also, intelligent LED drivers inside the luminaire can store and report a broad range of luminaire, energy and diagnostics data in a standardised format.


These luminaires are excellent platforms for the IoT, able to gather information from on-board sensors and delivering data for performance monitoring, asset management, predictive maintenance and numerous other tasks. Communication and data exchange with an external network takes place via a device's control device with wireless communication capabilities.


“Certification of D4i sensors and controllers is a significant milestone for our members and their customers,” said Paul Drosihn, DALI Alliance general manager. “The availability of qualified D4i control devices, alongside the many D4i drivers already available from numerous suppliers, brings further standardisation to the market and simplifies the specification process.”
