17. C. Objectives of Zhaga

18. The Zhaga mission
•
Zhaga will accelerate the adoption of LED lighting solutions in the marketplace
•
Zhaga-compliant products are upgradeable, future proof and suitable for all global markets
20 August 2014 18
LED modules and interchangeability shape the lighting industry

19. Zhaga defines interchangeable modules
•
Modules are interchangeable when the interface between luminaire and module is standardized
•
The luminaire manufacturer can use modules from different suppliers without changing the luminaire
•
Stable interfaces
–
LED innovation inside module
–
Stability on the outside
20 August 2014 19

20. An interchangeability example

21. The Zhaga logo
20 August 2014 21
•
Members may use the Zhaga Logo on products that implement a Zhaga specification
•
Compliance with the Zhaga specification must be verified
–
The verification is done by an authorized test lab
–
Zhaga can certify products which have been verified to be compliant
–
A certified product may carry the Zhaga logo

34. Zhaga recognizes the need for change
•
Zhaga is responding to the market need:
–
to enable LED modules and LED drivers that are independently interchangeable
–
in addition to Zhaga’s stated aim to enable interchangeability of LED light engines (LLEs)
•
Future editions of Zhaga Books will, where appropriate, reference relevant specifications that define the module-driver electrical interface
•
In the past:
–
Defining the module-driver interface would limit innovation
•Today:
–Technical solutions have emerged that make it possible to define module-driver interfaces for specific application segments without limiting the innovation in LED module and driver technology
20 August 2014 34

35. 20 August 2014 35
Interchangeable LLEs
•
Some LLEs contain a driver inside.
•Some LLEs consist of one or more LED modules together with a separate driver
• At present, Zhaga interface specifications (Books) define interchangeable LED light engines (LLEs)

36. 20 August 2014 36

LLEs with separate drivers
•
Currently, Zhaga does not define the electrical interface between the module(s) and driver
–
In the past, it was believed that defining this interface could limit design innovation for modules and drivers
•
In Zhaga Books, the LLE is treated as a single unit:

37. 20 August 2014 37
LLEs with separate drivers – current situation
•
Only the entire LLE is interchangeable
–
May not be possible to change the module(s) without also changing the driver, or vice versa

Current situation:
Zhaga does NOT define the electrical interface between the LED module(s) and driver.
 Only the entire LLE is interchangeable.
Future situation:
Defining the module-driver electrical interface will mean that modules and drivers are independently interchangeable.
Enabling full interchangeability
