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.

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. 

The deal has been widely welcomed in the lighting industry. Osram’s Arnulf Rupp, head of standardisation, told Lux the company was ‘excited’ by the development.

‘Establishing a standard Bluetooth mesh interface for D4i intelligent luminaries will open up industry opportunity and enable the deployment of even more advanced, interoperable IoT-enabled commercial lighting systems, while ensuring an equivalent light control behaviour between both standards,’ he said.

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.’

‘Commercial building owners around the world are being asked to improve energy efficiency while also enhancing the occupant experience,’ said Mark Powell, CEO of the Bluetooth SIG. 

‘The IoT-enabled intelligent lighting systems this collaboration enables promise to deliver the exact solution these building owners need.’

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. 

  • Lux has partnered with the Bluetooth SIG to bring you a series of webinars this summer on key aspects of Bluetooth mesh. The first one takes place at 11am BST on Thursday 11 June. Edward Lees, global head of technical product development at Feilo Sylvania, will walk us through the key benefits for lighting of Bluetooth mesh. It’s the perfect introduction to the platform and its applications as Lees takes the perspective of a lighting manufacturer and supplier.

At 11am BST on Thursday 18 June, the second webinar in the series will look at the advanced features and characteristics of Bluetooth mesh. Simon Slupik, chief technology officer at Silvair and chairman of the Mesh Working Group at Bluetooth SIG, is your presenter for this special Bluetooth Mesh Masterclass.

The webinar will look at radio network principles, the Bluetooth mesh principles of operation, security and provisioning, information publishing and subscribing, lighting models and distributed lighting control.
