The first EBV Lighting Academy took place in Munich on March 23rd and 24th.

In his function as Chair of the Zhaga Steering Committee, Arnulf Rupp from Osram GmbH gave an overview of the status and ongoing standardization activities of Zhaga. After explaining the aims of Zhaga and giving a quick summary of the older Zhaga Books, he focused on the current work on Books 9 to 11. These Books cover a module specification for a ring shaped LES of 12 or 25 mm (Book 9) and two extensions of the Book 3 specifications for a smaller module diameter of 35 mm (Book 11) and an enlarged 75 mm module size (Book 10). The first prototypes for the Book 9 specifications are currently being tested by authorized test centers.

An additional Book for driver specifications has just been started.  One very important issue is the specification of the driver interface for LLEs with external drivers to enable independent interchangeability of LED modules and drivers. An output current range from 50 mA up to 8 A will be covered by defining a relationship between IOUT and RSET.

Another, ambitious standardization task that is just starting, concerns COB LEDs. Split into two phases, the basic physical dimensions will be defined first and then the integration of new features and a higher integration level will be proposed in phase 2 (the first detailed articles on this Book will be published in LpR 51 – Sept/Oct 2015 issue).
