As lighting controls become more digitalized and the Internet of Things takes off, the need for defining standardizing the interface of sensors and connectivity modules with lighting has become a widely known issue in the lighting industry. Two organizations, Digital Illumination Interface Alliance (DiiA) and the Zhaga Consortium (Zhaga) are creating technology and devising standards for this area.
The Digital Illumination Interface Alliance (DiiA) is an open, global consortium of lighting companies that intend to grow the market for lighting-control solutions utilizing the Digital Addressable Lighting Interface (DALI) technology.
Zhaga, is a global association of lighting companies that standardizes interfaces of LED luminaire components, such as LED modules, LED light engines, LED arrays, holders, electronic control gear (LED drivers) and connectivity fit systems.
DiiA recently reported that it is “developing specifications for an optimized DALI interface inside luminaires, which will simplify the connection of luminaires to IoT networks.” At about the same time, the Zhaga Consortium reported that it “has finalized a new specification (Book 18) that helps to bring the Internet of Things (IoT) to outdoor LED lighting fixtures.”
Zhaga also indicated in the news release that the newly released Book 18 standard supports the merging of IoT and lighting technologies and helps futureproof the technology.
DiiA Devising Lighting Data Exchange Standard and Standard for Connecting Luminaire to InBuilt Communication Nodes
DiiA noted in its news release that it is standardizing the way in which DALI drivers can exchange diagnostic and measurement data in a well-defined format, and DiiA also pointed out that such a data model standard is essential for DALI products to participate in the IoT sector. Additionally, DiiA plans to devise interchangeable technology that simplifies the connection of luminaires to the IoT through inbuilt communication nodes.
The organizations have now signed a liaison agreement to share technical information about available and soon-to-be-released specifications and certification programs, and the timelines of these. According to the organizations, the first step will be aligning the DALI-based communication protocol with the Zhaga Book 18 specification.
“Both organizations understand the market needs and have decided to sign a liaison agreement,” said Ruud van Bokhorst, General Manager of DiiA, adding, “This liaison allows us to make the correct decisions on the best way forward in addressing this important market need.”
Giovanni Scilla, Chair of the Zhaga Steering Committee, commented, “By means of this liaison we aim to explore possibilities to define truly comprehensive specifications and certification programs, which will be the base for broad adoption of digitalization in lighting and increased speed to market.”
