Books 3 and 11: Spotlight module family
Zhaga Books 3 and 11 comprise a family of circular LED modules of different sizes, which are suitable for spotlighting and related applications.
The LED modules operate with a separate LED driver (electronic control gear). They are typically fixed to a heat sink using screws. The light output is essentially Lambertian to enable the luminaire optics to shape the application’s desired light distribution from a defined input.
The different Books describe modules with different outer diameters. Within each Book, there is a range of categories based on the diameter of the light-emittng surface (LES). Details are given in the Tables below.
Spot modules can be constructed using a COB LED array with the correct LES diameter, in combination with a circular COB holder.
