Book 9:
Ring-shaped LES

Zhaga Interface Specification Book 9 defines the interfaces of LED light engines (LLEs) comprising an LED module with a ring-shaped light-emitting surface (LES) and a separate LED driver (electronic control gear).

 

There are two LLE categories in Book 9, which are defined by the dimensions of the LES:

  • RL25 - LES ring with inner and outer diameter of approx. 20 and 30 mm, respectively
  • RL12 - LES ring with inner and outer diameter of approx. 7 and 17 mm, respectively

 

Book 9 modules could enable LED luminaire products for use in consumer lighting applications, such as small spotlights, track lighting and other compact luminaires.

 

This Book must be read together with Zhaga Interface Specification Book 1.
