Book 18:
Smart interface between outdoor luminaires and sensing / communication modules

Zhaga Book 18 describes a smart interface between outdoor luminaires and sensing/ communication nodes. It specifies power and communication aspects in addition to the mechanical fit and electrical pins. Zhaga Book 18 allows any certified node to operate with any certified luminaire. Certified luminaires and sensing/ communication modules are available from multiple suppliers, establishing an ecosystem of compatible products. The book simplifies the addition of nodes such as sensors and communication nodes to LED luminaires. By assuring plug-and-play interoperability, the entire value chain benefits. It reduces complexity and adds value for the luminaire maker, installer and the specifier.

Book 18 Edition 3.0 got approved in April 2021 and allows for architectures combining an ANSI C136.41 dimming receptacle with a Zhaga receptacle next to the architecture already specified in Ed. 2.0. This hybrid solution still offers the sensing use cases based on the Zhaga socket, that can also be positioned underneath a luminaire, and maintains the interoperability promise of Zhaga Book 18 Ed. 2.0.

To create trust in the interoperability of nodes and luminaires from different vendors, the Zhaga Consortium and the DALI Alliance (DiiA) have developed a Zhaga-D4i certification program. This program allows qualifying luminaires and nodes to carry the Zhaga and the D4i logo. Zhaga-D4i certification ensures that luminaires are future-proof and will be able to host the latest generation of nodes that fulfil the Zhaga-D4i requirements.
