Sodhi Intertech 2007 1

  1. 1. The beginning of a transformation – how LED’s are starting to re-shape general illumination applications
  2. 2. Presentation Overview • OSRAM SYLVANIA’s vision for LEDs • LED value chain • LED technology benefits and comparisons • General lighting market segments that are being impacted by LEDs • Barriers to LED adoption • LED business models in general lighting • Application examples • Conclusion
  3. 3. OSRAM SYLVANIA’s vision for LED lighting OSRAM SYLVANIA is committed to develop and promote environmentally friendly and energy efficient lighting systems. LED systems for general lighting, display backlighting and automotive headlamps reflect our current focus on commercializing this technology. We believe in using lighting technology to offer products that are useful, create new applications and are fun to use “We make better light for better living”
  4. 4. OSRAM global sales by business divisions FY 2006 Global sales for FY 06 Euro 4.6 Billion
  5. 5. OSRAM SYLVANIA’s commitment to energy efficiency
  6. 6. LED value chain: Bridging the gap between discrete devices and system solutions Chip Package Board Heat Optics Driver Light Power Fixture sink Source + Control OSRAM SYLVANIA OEM’s
  7. 7. Key advantages of LED’s for general illumination • Long life (50K hrs) • Directional light source • Small size • Flexible light source/unique looks/trendy • Color tunability of white light • Colored lighting • Energy efficiency/savings • Maintenance cost savings • Low voltage/safety • Rugged
  8. 8. Lighting Technology Comparison: Emission patterns vs. technology Directional Linear Array Chain Incandescent/ Halogen Fluorescent HID LED Systems
  9. 9. Lighting Technology Comparison: CRI vs. technology LED System Incandescent Induction FL Linear FL CFL HID HPSodium HID Metal Halide 0 20 40 60 80 100 120 CRI
  10. 10. Lighting Technology Comparison: Lamp LPW vs. technology LED System Incandescent Induction FL Linear FL CFL HID HPSodium HID Metal Halide 0 20 40 60 80 100 120 LPW

  12. 12. OSRAM SYLVANIA Application macro-segments for General Lighting General Illumination • Cove, wall-washing, undercabinet, freezer case, down lighting, street-lighting, display cases, task lighting, retrofits Decorative/Architectural lighting • Colormixing, colored lighting of building facades/coves, accent lighting Signage • Channel letter signs
  13. 13. From macro-segments to sub-segments: Matching LED attributes to general illumination segment needs Streetlighting/Tunnels Gas stations Parking garages Outdoor Landscape Billboards Signage Undercabinet High end retail Downlights Museums Shelf/Freezer case Medical/Patient rooms Indoor Cove High end residential Wall washing Residential Fixed color temperature Tunable white For each application metrics should be used to evaluate LED systems vs. the incumbent technology along the dimensions of lifetime, CRI, CCT, efficiency and cost
  14. 14. Downlight Application Example 32W TT CFL LED 1492 lm Lightsource Lumens 2400 lm -38% Light exiting fixture (after losses) 1134 lm 1134 lm CCT 3300 K 3300 K Typ Lm per LED instant-on 77.3 lm Typ # of LEDs 19 W 22.0 W Typ input power 35.0 LPW 45.7 LPW Typ efficacy (cc PS 90%) 32.4 +41% In certain cases LED luminaires can meet and exceed CFL luminaire efficacy!
  15. 15. Barriers to adoption of LED technology in General Lighting • Consistent quality of light »The “b” word for CCT…………. »CRI of some of the white light generation techniques (RGB, RGBW, RW…) • Standardization »Of terminologies »Of performance metrics »And eventually of light sources/systems • Initial system costs • Continued rapid pace of change in technology • Emergence of OLEDs, other inorganic LED technologies, improvements in existing lighting technologies
  16. 16. Binning challenges with LEDs for adoption into general lighting
  17. 17. Business models Lighting designer/ Architect Specifier Lamp Manuf. Fixture OEM Lighting agents/ End user Distributors Ballast Manuf. Contractor Lighting services org.
  18. 18. OSRAM SYLVANIA’s LED Lighting Value Proposition Light Source Power/Control Service/Support •Discrete LEDs • Power Supplies •Commercial Engineering • Class 2 Power Supplies • Specification support •LED Modules & Accessories • Various power/voltage •LED Lamps •SYLVANIA Lighting Services • Damp rated • Total Turnkey Lighting Solutions •Control Interfaces • In-field service • Dimming • Retrofit products and services • Color sequencing •Other • DMX, DALI, etc. • Custom systems design • Application development
  19. 19. General Illumination Application Segments: Façade lighting
  20. 20. General Illumination Application Segments: Cove Lighting Louis Polson Lighting
  21. 21. Decorative lighting applications: Hybrid LED/ Fluorescent downlights
  22. 22. General Illumination Application Segments: Cove Lighting
  23. 23. General Illumination Application Segments: Display case, Freezer case and Shelf lighting applications
  24. 24. Decorative lighting applications: Facade lighting, Architectural accents
  25. 25. General Illumination Application Segments: Undercabinet and Spot/Downlighting
  26. 26. Signage and Outdoor Lighting Applications
  27. 27. Conclusion • LEDs have started transforming the general lighting marketspace »Initial market penetration has been in specific application segments - signage, architectural lighting, down lighting, cove lighting, streetlighting, undercabinet, shelf lighting, display/freezer cases »LEDs will evolve to become one of the common general lighting technologies to compete with fluorescent and HID technologies »LEDs have to overcome “quality of light” performance barriers to deliver on customer expectations »Several alternative business models will evolve in the mid-term THANK YOU!
