Planar, circular LED light engines with integrated driver
Book 16 defines a family of planar, circular LED light engines (LLEs) with an integrated driver. Such LLEs are especially suited for use in flat, circular, low-luminance applications.
Book 16 has five LLE categories, defined by their maximum diameter. Two more sub-categories allow easy mounting in existing luminaires.
|Category||Maxiumum LLE diameter||No. mounting holes|
|D25 (A and B)||250 mm||4|
|D35 (A and B)||350 mm||3 or 4|

The specification will be published in mid 2017.
The Zhaga Consortium will review and update this specification from time to time. To ensure you are aware of any updates to the Zhaga specifications, please subscribe to the Zhaga newsletter.
This Book must be read together with Zhaga Interface Specification Book 1.
The maximum LLE height is very low, such that disc-shaped luminaires are a prominent application.
As luminance and power density is low, thermal management is easy. A dedicated heat sink is often not necessary.
The light-emitting surface (LES) is not specified. Most LLEs are expected to have a distributed LES on top of the LLE.
