DALI Simplifies the Complex IoT World for Luminaire Manufacturers


DiiA is developing specifications for an optimised DALI interface inside luminaires, which will simplify the connection of luminaires to IoT networks.

PISCATAWAY, NJ, USA – January 22, 2018 –

DiiA, the global DALI alliance, is taking further steps to bring the extensive benefits of DALI to the Internet of Things (IoT). Having established the DALI-2 certification process, which secures interoperability between DALI devices, DiiA is developing new specifications that extend the wellestablished DALI lighting protocol. These will create new possibilities for DALI technology in the IoT age, while making use of DALI’s strength as a robust, reliable and relatively low-cost communication technology optimized for lighting applications. DiiA is standardizing the way in which DALI drivers can exchange measurement and diagnostic data in a well-defined format. Such a standardized data model is essential for DALI products to participate in the IoT world. Building on this, DiiA is also seeking to simplify the connection of luminaires to the IoT via in-built communication nodes. “DiiA is helping to simplify the complex IoT world for the lighting industry,” says Ruud van Bokhorst, General Manager of DiiA. “Our new specifications will enable luminaires to connect to various IoT networks, while building on proven, standardized DALI technology.” The standardized data model will specify the content and format of measurement and diagnostic data, as well as the location of the data in the DALI driver. This will enable seamless data exchange between DALI products. For example, luminaires could provide power consumption data, allowing energy analytics and further improving servicing and maintenance within lighting systems.

Building on this harmonized data-model, DiiA is also developing a specification for DALI drivers to provide power to sensors and/or communication devices that are integrated into luminaires. This eliminates the need to provide mains power to the communication or sensor nodes, or to use a separate DALI power supply. The specification will simplify the creation of a DALI network inside a luminaire, and will enable intelligent lighting fixtures that can communicate with the IoT via DALIconnected sensing/communication nodes. This interface could also allow upgrading of luminaires to the latest IoT technology. DiiA welcomes all interested companies to become members and to participate in the development of new specifications and other DALI-related programs.
