Abstract

Recently new phosphors from various material classes have been developed for LED applications by Osram OS and partners. Excitation wavelengths of these phosphors range from below 400 nm to 470 nm, enabling the creation of purple and unsaturated LED colors and even the efficient conversion of near UV-radiation into white light. By addition of red and green phosphors to white LEDs, a warm white color impression can be achieved. These LEDs are suitable for all purposes of general lighting, where a high color rendering is required. An outlook to new applications with unsaturated and warm white LEDs will be given.
