Outline
What is the reason for the LED revolution, anyway?
What do we stand to gain with LED?
Barriers/Drivers
Actual Products
Explosion of products, to replace the existing technologies
Technology is changing so rapidly product life (in market) is
only about 12-18 months.
Products with completely new features are being introduced.

R&D and Manufacturing Barriers
Cost reduction/Performance Improvement
• LEDs
• Optics
• Electronics
• Thermal management !!
• Packaging
Reliability/Lifetime
• Poor understanding of system reliability
• Testing to reliably establish lifetime
Need faster and less testing
Compatibility with dimmers and sensors
New approaches for luminaires that take full advantage of LEDs
Manufacturing for high-volume and high-yield of luminaires & lamps
February 6, 2013 13
Two Product Directions
Retrofit products to fit into existing
luminaires/sockets
+ Energy savings quickly
+ Low installation costs
+ High volume potential in short
term
- Not optimally efficient (thermal)
Products for New Installations
+ Optimize for greatest efficiency
+ Add features for additional
savings (occupancy/daylighting
controls, etc)
- Low volume today
- Higher risk (no standards yet)
February 6, 2013 14
Market Barriers
Energy Savings wrt all conventional lighting
Affordable LED products
High quality products (avoid CFL story)*
Compatibility with infrastructure (dimmers, etc) for retrofits
Delay and expense of testing
• LM-80, LM-79, LM-82, TM-21
• DOE/FTC Lighting Facts
• Energy Star
• UL and other safety organizations
*But don’t force too-high standards!

Cost and Performance affect Market Acceptance
Over-focus on performance is just as likely to hurt market adoption as
over-focus on cost.
Cost focus.
Low cost is
“better” Performance
focus. High
perf is “better”

Major Driver: Cost Down
Goal for SSL products is generally a factor of 10 decrease in cost
from 2010 to 2015.
Necessary to reach high volumes.
Evolutionary progress
Architecture Breakthroughs

Other Drivers
Other drivers:
Efficiency increases will continue for both LEDs and lighting
