New developments of high power LEDs and challenges in lighting applications — •Christian Fricke — Neophos Development Pte. Ltd, Jocherstr.7, 85221 Dachau

Improvement of PowerLED structures is still at a tremendous improvement rate per year. Epitaxy, chip design, phosphor efficiency and package design see large improvements - The brightness of LED devices increased by a factor of 4 over the last 4 years and will certainly continue over the next years. Light quality and device cost for LEDs that are to be marketed for home and office lighting are key to successfully replace conventional lighting by LED solutions. Only when standardized modular systems are available to the market consumers will switch at an accelerated rate. Key performance indicators will be presented as well as an outlook to individual tunable light sources fitting to existing home / office installations.
