As part of “Advanced UV for Life”, a consortium of research institutes and companies which is being funded under the federal “Zwanzig20” program, Osram Opto Semiconductors is working with four partners on high-power UV LEDs for the mass market: the Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik (FBH), the Technical University of Berlin, LayTec AG and UVphototonics NT GmbH. Prototype LEDs and the technology for producing high-power LEDs for the UVB and UVC spectrums on the basis of the aluminum gallium nitride (AlGaN) material system are scheduled to be presented by 2020.
The partners are therefore pooling their scientific know-how and making their highly specialized technical facilities and analysis methods available. Development of the highpower LEDs is taking place along the entire technology chain for LED production. “The various tasks have been distributed among the partners on the basis of their strengths – everything from the production of structured sapphire substrates, epitaxy and chip processing to packaging and analytics”, said Dr. Hans-Jürgen Lugauer, Head of UV Development at Osram Opto Semiconductors. “With our presence on the international market and our expertise in industrial manufacturing we are boosting the impact of the consortium considerably,” he added.
