Interchangeability shapes the lighting industry 2. Zhaga – Goals and Philosophy 3. Zhaga specification books 4. Further plan of Zhaga 5. Conclusion S&R 2 Summary – Major Takeaways • Interchangeability is required by market and SSL development. It shapes the lighting industry. • Zhaga is driving the interchangeability worldwide as an open industry consortium for cooperation and sustainable SSL development. • Zhaga has thorough processes and principles to solve SSL interface problems and to meet market requirements. • The future is independent full interchangeability for SSL products. • Zhaga values strategic industry relationships. S&R 3 1. Interchangeability shapes the lighting industry What interchangeability means for SSL? No change in the luminaire when module is changed – No change in mechanical fixation (screws or clamp) – No change in optics (reflector or lens) – No change in heat sink Zhaga specs max LES diameter (mm) LES 9 9 LES 13,5 13.5 LES 19 19 LES 23 23 LES = Light Emitting Surface Same LES = no change in reflector and secondary optics © The Zhaga Consortium 5 Benefits of interchangeability A. Interchangeable modules for manufacturer • Lower development costs LLE A LLE B • Faster development • Easy for upgrade and maintenance • Lower risks (more sources, less stock etc.) Luminaire Luminaire Manufactured Installed • Reducing market entry barrier B. Interchangeable modules help customers Repair, Refurbish, Relamp LLE A End of life LLE B • Lower risk because of supplier independence • Lower price due to more choices and competitions Luminaire Luminaire Manufactured Installed Repair, Refurbish, Relamp End of life 6 S&R China Interface Standards / Specs Overview Interchangeability shapes the lighting industry Interchangeability situation and development trend International • Zhaga > 270 leading companies 8 books published Certification system • IEC Zhaga aims to transfer all mature specifications to the IEC; TC34 plans to adapt Zhaga’s specs (Book 3 as (1)public available specs =>(2) standards) China • TEAS 9 Interface standardization programs are defined and started • CSA 6 Interface standards published. CSA016-2013 for street lighting will be adapted as GB standard • Guangdong Province ‘Ant’ logo for ‘lighting unit’ introduced 4 layers defined: L1: packaged LED - 13 specs defined L2: LED array - 4 specs defined L3: LED module - 7 specs defined L4: Integral Luminaire & lamp Taiwan • TLLIA 6 interface related specs / standards proposed 2014 • Follow international standards • (waiting your inputs / update) Key success factors of the interchangeability: • International industry alignment and cooperation • Market acceptance • sustainable deployment 7 © The Zhaga Consortium 2. Zhaga - Goal and Philosophy Zhaga – an open industry consortium and cooperation More than 270 leading company members, including around 80 in the mainland and Taiwan More than 160 products certificated f2f meetings every 6-8 weeks with 70-90 participants • Set up and manage long-team interchangeability of LED Light Engines (LLE) in the world where we have rapid innovation and continuous changes in LEDs and SSL technology • Accelerate the adoption of LED lighting solutions in the marketplace – a). futureproof luminaire designs, b). multiple suppliers of comparable products, c). easier upgrade and maintenance • Define Stable interfaces – LED innovation inside – Stability on the outside • Certification to ensure the interchangeability © The Zhaga Consortium mechanical interface thermal interface electrical interface LED innovation inside optical interface 9 Out of scope: performance, quality and safety Government regulations Standards and Labeling Zhaga - Interface • safety • life time • energy efficiency • color stability • mechanical fit • light distribution • thermal behavior • electrical interface Companies • product specifications • data sheet Safety Interchangeability Performance Quality / Energy Detailed product specification Zhaga specifies the small key part of product properties © The Zhaga Consortium 10 Zhaga is focusing on module interchangeability Focus on a small key part of all specifications used for LED lighting SYSTEM LUMINAIRE MODULE © The Zhaga Consortium 11 Thorough analysis and deep technical study • • • • • Technical contributions from members Detailed review and revision Extensive membership surveys Deep strategic and technical analysis Precise and detailed interface definition (photometric, electrical, thermal, mechnical) • Sample implementations • Testing and measurements • Certification and logo licensing © The Zhaga Consortium 12 Certification and Testing • • • • Members may use the Zhaga Logo on products that implement a Zhaga specification Zhaga will certifies products that have been tested by an Authorized Test Lab.
