Overview of Zhaga Books

Zhaga is creating a series of specifications, known as Books. Each Book defines one or more components of an LED luminaire. Such components include LED light engines, LED modules, LED drivers, LED arrays, holders, and connectivity fit systems.

Books define the mechanical, photometric, electrical, thermal, and control interfaces of the component to its environment. Defining the components in this way makes them interchangeable in the sense that it is easy to replace one component with another (either at the manufacturing stage, or in the field), even if they have been made by different manufacturers.
