scope:

This Book 10 defines interfaces between LED Modules, associate components (Holders) and luminaires. Not all interface descriptions are applicable to LED Modules or Holders, but where applicable they are identical.

The scope of the interface descriptions is focused on a range of LED Modules with a circular shape and high luminance LES. A LED Module is intended to be fixed to a luminaire heat sink by means of screws. Its light output distribution is primarily Lambertian, to enable Luminaire Optics to shape an application-specific light distribution independently of that of the LED Module.

Zhaga Book 12 defines an LED (Chip on Board) Array component, which shares certain interface descriptions with this Book 10 (mainly photometric). It is possible to combine a Book 12 compliant LED Array with a Holder that ensures mechanical and electrical fit of the assembly. The Holder provides its own set of mechanical/electrical/thermal interfaces to a luminaire. If these interfaces are compliant with the interface descriptions in this Book 10, the Holder+LED Array assembly can be used in the same way as an LED Module compliant with this Book. Thus this Book can also be used to check compliance of Holders with respect to the Holder-Luminaire interface.

This Book 10 defines several size categories of the LED Module

• 35 mm, 50 mm maximum outer diameter

The size categories can have different LES diameters and different LES categories:

• LES6.3, LES9, LES13.5, LES19, LES23

The LED Modules are intended to be installed and replaced by professionals only.
