Zhaga has announced the release of Book 20, which focuses on the smart interface between indoor luminaires and sensing/communication modules. Book 20 brings together complementary specifications from the Zhaga Consortium and the D4i specifications from the Digital Illumination Interface Alliance (DiiA). Book 20 is intended to ease invest decisions for end-users, as luminaires can be adapted when needed with modules for different functions, like air quality sensing, presence detection or light levels controlling.
The specification provides benefits to luminaire makers, when certified modules from multiple suppliers providing a wide range of different functions are available. It also helps installers, as a certification on the interoperability of components exists. The new Zhaga-D4i certification is available for LED luminaires that incorporate LED control gear fulfilling the D4i requirements. Luminaires can now be certified by Dekra and Intertek, as the Zhaga accredited test centers. Zhaga-D4i certification of sensors and/or communication modules will become available later in 2020.
