  1. ACON • LED Revolution in Lighting • - Kartik Bakeri • Suveg Electronics SYNERGY FOR ENERGY 2012 www.suvegelectronics.com

  2. Company Profile ACON • Suveg Electronics, part of Bakeri Group is an ISO 9001:2008 certified company, established in 1985 • We deliver market-leading products with improved energy conservation, distinctive styling & accustomed to hostile environmental conditions • Many of our innovations are patented & designed to give maximum light output along with enhanced energy saving • Testing carried out at UL, & ERDA, as per International Standards www.suvegelectronics.com

  3. LED Revolution in Lighting -This presentation endeavors to give a fundamental outlook on why, where, where not and what’s of LED in the world of lighting. - LED lighting for general illumination - Where to use LED - Efficiency, cost economics and maintenance required - How to select the right LED luminaire? - Knowledge of LM 79, LM 80 EMI/EMC standards and certain thermal aspects - Verification after installation whether the luminary has been delivered as per the specifications promised

  4. Application • Efficacy, Cost, Cost of Electricity generation, Life, Maintenance, warrantee as compared to other efficient light sources such as T5, CFL, sodium vapour, induction lamp, etc. • Use of lenses increases the usable efficiency • So, application in street lights, industrial high bay, solar, table lamps, work bench, sign boards/hoardings, and other task lighting www.suvegelectronics.com

  5. Main Contents of LED fixture • LED/s • MPCB for the LED/s • Heat Sinking Housing • Optics and/or toughened glass cover • Driver/s (Electronic circuit) – the heart

  6. Standards & Compliance • Apart from the general standards like Ingress protection, etc. • Specially applicable to LED luminaries : IS 1610X/LM79 and EMC standards LM79 : Luminous characteristics EMC : Compliance to electromagnetic standards www.suvegelectronics.com

  7. IESNA –LM-79-2008 • Power consumption • Luminous Flux (Lumen) • System Efficacy : Lumen/Watt :- 70-80 lm/W is practical at present • Power Factor : Preferably greater than 0.98 • Field angle and Beam angle • CCT & CRI • Photometry www.suvegelectronics.com

  8. Correlated Colour Temperature (CCT) & Colour Rendering Index (CRI) CCT : 4000 to 6500 preferable for general illumination CRI : preferably > 70 www.suvegelectronics.com

  9. Asymmetric batwing pattern – Street Light • An ideal Polar Curve for the street light www.suvegelectronics.com

  10. Corresponding Light Intensity Data Source: UL Report No. 6012-001708-01-01- ACON SL_90W www.suvegelectronics.com

  11. ¥ = 30° C = 0° ¥ = 60° C = 0° Road with Angular diagram ¥ = 60° C = 90° ¥ = 60° C = 70° www.suvegelectronics.com

  12. IES file : whether matching IS1944 www.suvegelectronics.com

  13. 9 Point Method : A practical approach • Avg Lux= (A+B+C+D)/16 + (E+F+G+H)/8 + J/4 A F C E G J B H D www.suvegelectronics.com

  14. Case Study 9 Point Calculation

  15. EMC Harmonics Emission Immunity Conducted Radiated www.suvegelectronics.com

  16. EMC : Supply Current THD < 10% • Supply Current total Harmonics Distortion should be < 10% THD < 10% with low conducted Emission THD < 30% with high conducted Emission Supply Current Waveforms www.suvegelectronics.com

  17. EMC Emission : EN 55015 limits • Quasi-peak & Average Limits and obtained Average at mains terminals www.suvegelectronics.com

  18. Immunity as per IEC 61547 • Injected current (common mode radio frequency) • Fast transient (5/50 ns pulses) • Radio frequency Electromagnetic field • Surge Test (1.2/50 µsec) • ESD (Electrostatic Discharge) www.suvegelectronics.com

  19. IESNA-LM-80 • LED tested @ Tj=25º C V/s • Tj=85º C www.suvegelectronics.com

  20. Summary Test Reports • LM 79 for photometric data • THD < 10% • Conducted & Radiated Emission as per EN 55015 • Immunity as per IEC 61547 • LM 80 test for LEDs at Tj =85º C Physical Verification • Supply Current Waveform for THD & Conducted Emission • Consumption & Power Factor • 9 Point AvgLux measurement www.suvegelectronics.com
