World record in the OSRAM laboratory: quantum leap in the brightness and efficacy of white LEDs
Concentrated know-how produces top performance
The key to success was the efficient interplay between all the advances made in materials and technologies. A perfectly matched system of optimized chip technology, a highly advanced and extremely efficient light converter and a special high-performance package combined to produce the world records - 155 lm for brightness and 136 lm/W for efficacy. The semiconductor light sources are also suitable for high operating currents. At 1,4 A they can produce up to 500 lm of white light. This means that the LEDs can later be used not only for general lighting tasks and automotive applications but also for LED projection as blue and green chip versions.
Dr. Rüdiger Müller, CEO at OSRAM Opto Semiconductors, commented: "It was the successful combination of OSRAM know-how in different fields that led to these new records in efficiency and brightness. Starting with the light converter we will be gradually moving the new developments into production". OSRAM has already applied for patents for the technologies that lie behind these records.
