Zhaga publishes Book 18 Edition 1, allowing mechanical IoT upgradability
August 15, 2018 — The Zhaga Consortium has published Edition 1 of a new specification that helps bring the Internet of Things (IoT) to outdoor LED lighting fixtures.
The specification, known as Zhaga Book 18, makes it easy to upgrade LED fixtures by adding or changing modules that provide sensing and communication capabilities, the organization says.
The full version of Book 18 Ed. 1 can be downloaded here.
Book 18 Ed. 1 defines a standardized mechanical interface between a receptacle on the exterior of the LED luminaire and a sensing and communication module that fits into the receptacle.
According to Zhaga, the standardized interface means that the module can be easily replaced in the field, allowing the luminaire to be upgraded via the addition of new smart capabilities. The luminaire can also be shipped with a blank cap in the receptacle, allowing a module to be field-installed at a later date if required.
Additionally, to the mechanical interface, Zhaga has started the development of Ed. 2 of Book 18, aiming to add requirements for the electrical and control interface, which are not specified in Ed. 1. This would enable interoperability of modules that provide sensing and communication capabilities to outdoor LED lighting fixtures.
