The objective of this work is the development of processes to double or triple the light output power from green and deep green AlGaInN light emitting diode (LED) dies within 3 years in reference to the Lumileds Luxeon II. Lumileds Luxeon II dies and lamps have been identified by the Department of Energy as the uniform reference of current performance levels and therefore will be used in our performance comparisons. This project will pay particular effort to all aspects of the internal generation efficiency of light. LEDs in this spectral region show the highest potential for significant performance boosts. The results will be high output green and deep green (525 - 555 nm) LED chips as part of high efficacy red-green-blue LED modules. Such modules will perform at and outperform the efficacy target projections for white-light LED systems in the Department of Energy's accelerated roadmap of the SSL initiative.
