Large outdoor displays (single and full color)! However, several fast-growing emerging segments are showing positive growth:! Backlights for notebook PCs and LCD TVs! Lighting 23
24 LED Backlights for Notebook PCs! Saw rapidly growing adoption in 2008! Penetration was about 12% for the year, up from 3.5% in 2007; could exceed 50% in 2009! HP, Dell, Apple, Acer, etc. all had new LED backlit models (Dell will go to 100%)! Aided by popularity of ultra-portables, or netbooks, which mainly use LED backlights! Low-cost (<$400), lightweight, minimal functionality, small screens (8-10 inches)! Around 13 million units shipped in 2008; expected to double in
25 LED Backlights for LCD TVs! All major LCD TV manufacturers have LED backlight programs! Many new models introduced in 2009! Samsung, Sony, LG, Sharp, JVC, etc.! Samsung is the most aggressive, with models in the market from Q4 2007! Expects substantial penetration in 2009! Product differentiation, positive profit margin! Price differential with CCFL backlights has been reduced, but still high (~$ at retail) 25
26 Backlights for LCD TVs (cont.)! Even though unit sales of LCD TVs are projected to grow ~20% in 2009, revenues are forecast to decline! Implies severe pricing pressure, continuing the trend seen in Q4 2008!ASPs forecast to decline 30%! How will higher-priced sets with LED backlights do in this environment? 26
27 Backlights for LCD TV (cont.)! Backlighting approach has evolved! First Sony models used high-power RGB LEDs in an edge-lit configuration! Color gamut advantage over CCFL! Samsung developed the direct backlight approach, using low-power, enhanced white LEDs! Enabled local dimming/high contrast ratio, also wide color gamut! More recently, thin is in ; edge-lit configuration gives slim profile! Again, Samsung is the leading adopter! Tradeoff between local dimming and slim profile(?) 27
28 New LED Backlit LCD TVs!

Strictly speaking, organic LEDs (OLEDs) are also included in this definition, but they are still several years away from commercialization for lighting applications 32
33 Lighting Market Definition! Lighting Market Segmentation! Lamps light source (~$20 billion)! Ballasts -- power! Fixtures! LED Lighting Fixtures ~$80 billion! Convergence of lamps, ballasts and fixtures! Replacement LED lamps as intermediate solution! LED lighting fixtures - integrated long-term solution 33
34 Elements of an LED Lighting Fixture Fixture Enclosure 34
35 Designing LED Fixtures Fixture Function - Task light, decorative, outdoor, wet environment Thermal Management Optics Drivers Technical Features - Light output, color, intensity LED Light Engine Regulatory Requirements - UL, IES, ANSI, Energy Star, Title Fixture Design Esthetics Testing Decision flow 35
36 Design Challenges! Each LED supplier has a different package! No standard drivers or power supplies! Optical design is different for each application! Thermal management must be designed for application environment; i.e. indoor, outdoor, exposed to air, recessed in ceiling, etc. 36
37 Overall LED Fixture Design! Fixture design needs to incorporate all the preceding elements into a system that optimizes the utilization of LED light output! In the lighting industry, the esthetics of fixture design is often of key importance, with lower emphasis on cost! For practical applications, fixture cost is a primary consideration, especially because of the high cost of LEDs relative to other light sources 37
38 Efficient Fixture Design is Key to Utilizing High Efficiency of LEDs Example: Efficient Design Start with 90 lm/w 1-W white LEDs (rated at 25 C junction temperature) Assume: 90% electrical efficiency; 90% optical efficiency; operate at 65 C junction temperature Fixture efficacy = 90 x 0.9 x 0.9 x 0.85 = 62 lm/w Example: Inefficient Design Start with 90 lm/w 1-W white LEDs (rated at 25 C junction temperature) Assume: 80% electrical efficiency; 85% optical efficiency; operate at 100 C junction temperature Fixture efficacy = 90 x 0.8 x 0.85 x 0.75 = 46 lm/w 38
