Description:

This is a method for solving efficiency droop in high power nitride LEDs. Aluminum and Gallium Nitride (GaN) layers in lattice structures are used, which allows for improved performance of LEDs.  A US provisional application, 61/286,821 has been filed for this technology and was converted to a utility application in December 2010

The Market

The SSL market is predicted to reach $33 billion by 2013 with a compound annual growth rate (CAGR) of 10.67%. [1] This market is an umbrella market for LEDs, OLEDs, and PLEDs. LED technologies make up a majority of this market ($5.08 billion), with a growth rate of over 24%.[2] The OLED market is also predicted to grow at a considerable rate, about 24.7%, with a market size of $730 million. [3] Twenty-two percent of the United States electricity is consumed by lighting, which costs consumers over $50 billion each year. SSL technologies have the potential to reduce this consumption by up to six times less. This potential has led to increased market need, funding resources and science centers dedicated to SSL development, such as the $46 million Energy Frontier Research Center (EFRC) for solid-state lighting science funded by the Department of Energy.
