1 From specifications to applications: Zhaga at Light+Building 2012 Frankfurt, April 15 th 2012

2 A bright LED future with Zhaga 189 members from Europe, Asia and the US to date Including luminaire and lamp manufacturers, LED module makers and companies that supply the lighting industry 15 April

3 More than 30 companies show Zhaga-compliant products Zhaga-compliant light sources are interchangeable Why is interchangeability important for the lighting industry? Zhaga created specifications for 6 different LED light sources What are these 6 Zhaga specifications? More than 30 companies show Zhaga-compliant products Where can you see these Zhaga-compliant products? 15 April

4 Interchangeable light sources The lighting industry is used to work with standardized light sources E27, G5, G9, 15 April

5 LED light sources are not interchangeable today Most LED light sources are not interchangeable, until now Typical differences are: fit with heat sink (2, 3, or 4 screws) size of the heat sink size of the light emitting surface height of the light emitting surface Problem: Change LED => Change heat sink & reflector in luminaire 15 April

6 Zhaga: interchangeable LED light sources Zhaga makes LED light sources interchangeable The main parameters are: Mechanical and thermal fit with the heat sink Size of the light emitting surface Height of the light emitting surface Photometric properties of the light emitting surface 15 April

7 The six Zhaga interface specifications Book 2: Socketable LLE with integrated ECG Status: finalized February 2011 Book 3: Spot LLE with separated ECG Status: finalized July 2011 Book 4: Street Light Engine Status: finalized in March 2012 Book 5: Socketable LLE with separate ECG Status: finalized September 2011 Book 6: Socketable LLE with integrated ECG Status: finalized December 2011 Book 7: Office LLE with separate ECG Status: finalized in April April

8 What are interface specifications? Zhaga specifies the outside properties of the light source: mechanical fixation thermal behavior electrical properties photometric properties The inside is not specified. Manufacturers can make their own internal engine design. Innovation continues inside this 'Black Box. 15 April

9 Not performance or quality only interchangeability Zhaga specifies the minimum needed to achieve interchangeability Zhaga does not specify quality and performance aspects, such as: life time, color stability, energy efficiency, or safety Zhaga enables product differentiation and application-specific trade-off between cost and performance 15 April

12 Zhaga at Light+Building 2012 Selected impressions from the fair 15 April

13 The benefits of interchangeable LED light sources Greg Galluccio Director, LED product development Lighting and Energy Solutions Division

14 Leviton Manufacturing Company Zhaga Full Contributing Member Lighting products currently made by Leviton: Lampholders Dimmers Wireless Controls Occupancy Sensors Ballasts and Drivers 15 April

15 Challenges for manufacturers in the LED market: Chaotic market rapid development, proprietary form factors and interconnects Lack of standardization or agreed-upon specifications Uncertain customer base Patent mine field 15 April

16 Challenges for manufacturers in the LED market: Conflicting/confusing information Unproven claims Inability to interchange products makes it difficult to Upgrade products Source replacement parts Interconnect different parts of a system Merge old technology with new technology + + =?? 15 April

17 Benefits of Zhaga Membership: Companies at every functional tier of the industry participate The best Solid State Lighting expertise in the world is gathered in one place Open communication no proprietary systems Equality of influence 1 vote for each participating company One common goal for all - interchangeability! 15 April

18 The fact that products are made to be interchangeable does not mean that everyone will build the same thing. 15 April

19 The endgame. For Manufacturers Leviton can design its components and subsystems to interact effectively with other Zhaga certified products to create highly effective and versatile working systems For Customers Users of Zhaga certified products can be confident that those products will perform properly when used with other Zhaga certified products regardless of manufacturer 15 April

20 Zhaga Book 3: Spot Light Engine Dawson Liu President, Lustrous Technology

21 Introduction of Zhaga Spot Light Engine

22 System Overview Book 3 of the System Description Zhaga defines a Spot LED Light Engine with separate Electronic Control Gear and a Luminaire 15 April

23 Mechanical Interface LED Module Geometry The spot light engine parameters define only maximum outlines, meaning that LED Module may also be smaller if technically feasible Only the features relevant to interchangeability like the screw holes and their positions and the OCA are specified with bothsided tolerances 15 April

24 Mechanical Interface LED Module Connection An electrical interconnect should be placed symmetrically at the LED Module X axis This limitation is to ensure the interchangeability of the LED Module y X 15 April

25 Mechanical Interface Optical Contact Area (OCA) The LED Module have a physical surface of the housing denoted as OCA The position and dimensions of this OCA are depends on the Light Emitting Surface (LES) LES OCA 15 April

26 Mechanical Interface Locking Ring System (LRS) The Locking Ring System is an optional accessory that enables toolless mounting of the module 15 April

27 Photometric Interface Lighting Emitting Surface (LES) The LES for spotlight application shall be described by a 2- dimensional circle having the smallest possible diameter In the case of a diffuse cover covering the LEDs, the LES shall be described by the functional area of the diffuse cover 15 April

28 Photometric Interface Luminous Flux The Luminous Flux of an LLE shall be in one of the category listed in Table as below (Total 9 categories) The operating condition shall follow the requirement of the Zhaga specification 15 April

29 LUSTROUS Spot Light Engine

30 LUSTROUS Spot Light Engine LUSTROUS Z, series Standard Type Design for the Zhaga spot light engine Satisfy all the interface specification 15 April

31 LUSTROUS Spot Light Engine Luminous Flux Distribution LUSTROUS Z, series has the ability to generate the flux category from C006 to C050 for different purposes 15 April

32 LUSTROUS Spot Light Engine Optical fixing LUSTROUS Z, series is able to be fixed by two type reflector Screw Type Locking Ring Type LLE fixed by screw LLE fixed by reflector LRS was designed by AAG. STUCCHI 15 April

33 Summary

34 Benefits from Zhaga How can luminaire manufacture beneficial from Zhaga Spot Light Engine? Unify the mechanical specification of LLE which provides quick installation for any LED light source in same luminaire Easy to choose different flux category for different purposes Thermal issue can be solved by the interoperability check Fast installation makes the fabrication easier Clear test procedure make the LLE with Zhaga logo sustain its reliability By giving standardize dimension, luminaire manufacture can have fully focus on their design 15 April
