Transcript

  • 1. ZhagaInterchangeability specifications of LED Lighting light + building 2012 Frankfurt, April 18th 2012
  • 2. Norbert WittigPanasonic Lighting Europe –International StandardizationChair of Zhaga TCWGSecretary of IEC TC34 WG COMEXChair of the German EMC Committee for LightingChair of the Technical Committee ZVEI Lighting 2 • • 17/04/12
  • 3. A bright LED future with Zhaga 193 members from Europe, Asia and the US to date Including luminaire and lamp manufacturers, LED module makers and companies that supply the lighting industry 3 • 17/04/12
  • 4. What does “Zhaga” mean?The word ‘Zhaga’ has no intended meaning. It is a waterfall in Sichuan.The brand ‘Zhaga’ stands for interchangeable LED light sources. 4 •
  • 5. Interchangeable light sources• The lighting industry is used to work with standardized light sources – E27, G5, G9, … • 5 • 17/04/12
  • 6. 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 6 • • 17/04/12
  • 7. 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 7 • • 17/04/12
  • 8. What is an LED light engine?• An LED light engine is the combination of an LED module and its associated electronic control gear (‘driver’). • 8 17/04/12
  • 9. Control gear integrated or in separate housing• An LED light engine can have integrated control gear, or control gear in a separate housing LED Light Engine LED Light Engine LED module LED Module Control cable Control Gear Gear integrated control gear control gear in separate housing • 9 • 17/04/12
  • 10. The interfaces of a light engine1. Mechanical Interface related to dimensions incl. “socket”2. Photometrical Interface related for example to lumen output, color, light distribution3. Thermal Interface related for example to thermal resistance, heat dissipation4. Electrical Interface related to Power (AC or DC), insulation, earth and Controls (by reference to existing specifications) 10 • • 17/04/12
  • 11. What are interface specifications?Zhaga specifies the outsideproperties of the light source:− mechanical fixation− thermal behavior− electrical properties− photometric propertiesThe inside is not specified.Manufacturers can make theirown internal engine design. 11 • 17/04/12
  • 12. The six Zhaga interface specifications Book 2: Socketable LLE Book 3: Spot LLE Book 4: Street Light Engine with integrated ECG with separated ECG Status: finalized February 2011 Status: finalized July 2011 Status: finalized in March 2012 Book 5: Socketable Book 6: Socketable LLE Book 7: Office LLE with LLE with separate ECG with integrated ECG separate ECG Status: finalized September 2011 Status: finalized December 2011 Status: finalized in April 2012 • 12 17/04/12
  • 13. 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 13 • 17/04/12 •
  • 14. Benefits of Zhaga:• 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 • 14 17/04/12
  • 15. The fact that products are made to beinterchangeable does not mean that everyone will build the same thing. 15 • 17/04/12
  • 16. More than 30 companies show Zhaga-compliantproducts• 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? • 16 • 17/04/12
  • 17. Zhaga at light+building 2012Selected impressions from the fair 17 • 17/04/12
