The use of UV-C radiation to eliminate bacteria, such as light disinfection, is increasingly becoming a core technology of global concern. It can be widely applied in various scenarios such as hospitals, offices, kitchens, and bathrooms, and can even achieve efficient disinfection of tap water with UV-C radiation. The all-new UV-C LED from AMS Osram has a wavelength of 265nm at a power of 200mW, with an operating efficiency of over 10% and a lifespan of over 20000 hours. With excellent performance parameters, it is expected to replace traditional mercury vapor discharge lamps in the future. The working efficiency of this LED has been verified by the Physikalisch Technische Bundesanstalt (PTB) in Germany.

Eliminating pathogens from surfaces, liquids, or air is an indispensable part of protecting human health and environmental safety, whether in daily life or various industrial scenarios. The use of high-energy UV-C radiation for residue free disinfection is becoming an increasingly critical solution in this field.

In addition to UV-C LEDs, common radiation sources with disinfection functions also include low and medium pressure discharge lamps. Due to the presence of mercury in these lamps, they pose health and environmental risks during production, use, and disposal processes. Therefore, as a more sustainable alternative, the market demand for UV-C LEDs is continuously increasing. However, so far, its work efficiency has not reached the level of traditional technology, so it cannot fully replace the application status of traditional mercury lamps.

Dr. Ulrich Steegmueller, Senior Vice President of Research and Development at the Optoelectronic Semiconductor Division of AMS Osram, stated, "We are vigorously focusing on the development of sustainable products. As a leading global LED manufacturer, our mission is to continuously break through and improve UV-C LED technology to support an increasing number of application scenarios. To this end, AMS Osram is continuously promoting technological innovation in multiple fields such as epitaxial processes, chip and packaging design. Recently, AMS Osram has successfully optimized the UV-C radiation extraction efficiency of LEDs, significantly improving radiation output in various application scenarios. The electro-optical conversion efficiency (WPE) of this LED exceeds 10% and guarantees a long lifespan of over 20000 hours. Compared to the previous WPE of about 5.3%, the AMS Osram has almost doubled its efficiency under the same conditions.

The peak performance mentioned above has also been verified by the German Federal Institute of Physical Technology, whose test results confirm that the electro-optical conversion efficiency (WPE) of AMS Osram UV-C LED products reaches 10.2%. In addition to the improvement in optical performance, AMS Osram has also successfully demonstrated that the tested samples have a lifespan comparable to high-power LEDs currently available on the market.

The verification of peak efficiency and excellent lifespan is an important technological breakthrough and sustainable milestone for the future development of AMS Osram. The new UV-C LED is expected to be launched on the market by the end of 2026 and will further enhance the product portfolio of advanced UV-C lighting solutions from AMS Osram. AMS Osram has firmly established its intellectual property advantage in the field of UV-C LED technology with over 200 high-quality patents.
