Bluetooth mesh and Dali
A technology breakthrough for the lighting sector was hailed today as the organisations behind Bluetooth mesh and the Dali-2 protocols agreed the specification for a standard interface.
The move will allow Dali light fittings to talk to Bluetooth mesh wireless lighting controllers.
It’s believed that the agreement between the Bluetooth Special Interest Group and the Digital Illumination Interface Alliance will accelerate the development of intelligent and connected lighting systems.
Dali is the most widely adopted and recognised open standard in the lighting sector while Bluetooth mesh is an innovative platform is which devices pass information between them, ideally suited to luminaires.
The collaboration between Bluetooth SIG and the DiiA will enable the deployment of certified Dali-2 devices and intelligent D4i luminaires, which have an internal Dali network, with qualified Bluetooth mesh intelligent lighting-control networks.
Paul Drosihn, the DiiA’s general manager described the combination of Dali-2 and Bluetooth mesh as ‘a natural choice’ for the lighting industry. ‘The combination enables sensor-rich lighting systems and will deliver powerful new IoT capabilities to building managers.
This will include automated light-level and colour control, advanced luminaire performance monitoring including energy usage and predictive maintenance, as well as enhanced services such as asset tracking and indoor navigation.’
To help streamline the delivery of products to market, the Bluetooth SIG and DiiA are also working together to make it easier for suppliers to complete both the Bluetooth product qualification and Dali-2 product certification processes necessary to ensure interoperability.
