Why Printed Electronics for SSL? Four Themes 1. Where does the Light come from? 2. Why should I care about Solid State Lighting (SSL)? 3. Can I make money in this Market? 4. What are the Value Chains and Supply Chains? General Lighting Signage Ubiquitous Displays Incandescent CFL LED OLED

Light Driven Value Chain
The Lighting Challenge According to the Department of Energy (DOE), lighting accounts for 8% of all energy consumption in the United States and 22% of electricity nationwide. LEDs have the potential to reach 200 lm/w, compared to the efficacies of incandescent lamps at 15 lm/w and fluorescent tubes at 90 lm/w. If solid-state lighting replaced all existing lights, the DOE estimates customer savings of $115 billion by 2025 and a 10% reduction in greenhouse emission gases. US DOE Solid-State Lighting Research and Development: Multi- Year Program Plan, March 2010, Higher efficiency and lower environmental impact are the major drivers
