IEE LED Lighting project

To develop a $1 LED light bulb that is 20 times more efficient than incandescent bulbs.

Lighting consumes 22% of all US electricity.  The Department of Energy estimates that widespread adoption of LED lighting can reduce energy use by 46% by 2030 – the equivalent of 50 one-GW coal-fired power plants.  

Institute researchers are working to clear the last remaining hurdles to achieving high-quality, efficient and widely-available solid-state lighting. 


Efficient Blue and Green LEDs Refining blue and green LEDs, which are needed to produce efficient LEDs with high-quality light; and improving luminous efficiencies to greater than 250 lumens/watt.  
Advanced Light Extraction and Packaging Developing advanced light extraction and packaging techniques to extract the maximum amount of light possible out of LED chips.
Bulk Crystal Growth Institute researchers have pioneered the growth of large area, single crystal gallium nitride (GaN) substrates and are now pursuing the faster growth rates and level of quality needed for commercial production.
Laser Diodes We are researching ways to make laser diodes smaller and cheaper, and achieve efficient laser-based white lighting.
