20 August 2014 12

Zhaga is Driven by Strong Market focus

• Zhaga is an industry consortium – Our members are companies from the lighting industry

• Zhaga takes its requirements from the market

– Choosing the best technology and market solution – no politics

• Zhaga addresses industry problems – Addressing supply chain problems – Addressing manufacturing problems – Addressing market growth opportunities

20 August 2014 13

Industry liaison relationships

20 August 2014 14

• Zhaga has strategic industry relationships – GLA (Global Lighting Association) – And many others…

Zhaga invites more strategic industry relationships

Possible ways to cooperate (subject to agreement)

• Share information • Share requirements • Endorse and support each others events and conferences • Align and harmonize work plan • Adopt and publish each others technical specifications

– Translate technical specifications into local language

20 August 2014 15

Latest news! • Signed liaison agreement contract with TEAS

– Thursday July 24, 2014

• Ongoing discussions with CSA about liaison agreement contract

• Ongoing discussions with Shanghai LED organizations – Encourage use, implementation and deployment of Zhaga

interface specifications in China

20 August 2014 16

C. Objectives of Zhaga

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

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

An interchangeability example

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

•Abbreviations:

•LLE = LED light engine

•LES = Light-emitting surface

•ECG = Electronic control gear (= LED driver) • Zhaga Book portfolio:

– Started in professional space, now entering into consumer space – From stand alone module form factors to scaled families

• Office module range (Book 7) • Spot range (Book 3, Book 10, Book 11)

– Further Books being considered (eg Outdoor and COB)

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

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)

Cable

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:

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
