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

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 well-
established 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 DALI-
connected 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.
The Digital Illumination Interface Alliance (DiiA) is an open, global consortium of lighting companies that aims to grow the market for lighting-control solutions based on Digital Addressable Lighting Interface (DALI) technology. DiiA was established in response to industry requests for an independently-verified DALI-2 certification program that covers the functionality specified in version 2 of the IEC 62386 family of international standards. DALI-2 certification brings the promise of significantly improved interoperability and additional functionality compared with current DALI systems in the market. DiiA is a member program of the IEEE Industry Standards and Technology Organization (ISTO). For more information, see www.digitalilluminationinterface.org.
