Ultrabright WLEDs shine at 136 lumens/W efficacy
Keywords:ultrabright WLEDs? high efficacy white LEDs? high-power LEDs?
Key to the success was the efficient interplay between all the advances made in materials and technologies. A perfectly matched system of optimized chip technology, an advanced and extremely efficient light converter and a special high-performance package combined to produce the world records: 155 lumens for brightness and 136 lumens/W for efficacy. The semiconductor light sources are also suitable for high operating currents. At 1.4A, they can produce up to 500 lumens 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.
"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," commented Rudiger Muller, CEO of Osram.
The company has applied for patents for the technologies behind these achievements.
