    Excellent optical output power and electro-optical conversion efficiency (WPE) : a typical value of 115mW, an efficiency of 5.3%;
    Ultimate bactericidal efficiency: peak emission wavelength 265nm;
    Compact and durable design: Excellent R70B50 life, more than 20,000 hours.

    Shanghai, China, November 8, 2024 - AMS OSram (Swiss Stock Exchange: AMS), a leading global provider of optical solutions, today announced the launch of the new OSLON UV 3535. This innovative UV-C LED is designed to meet the growing demand for mercury-free, highly efficient UV-C disinfection and therapeutic solutions. The LED single chip emits light with a wavelength of 265nm and an output of up to 155mW to achieve the ultimate bactericidal effect. Combined with its superior electro-optic conversion efficiency, this carefully optimized system-level solution is designed to meet customer needs in UV-C disinfection applications.

    Nina Reiser, Senior product Manager, UV-C product line, AMS Osram, said: "Ams OSram's breakthroughs in package design and semiconductor technology are leading the way in UV-C solutions that combine performance, quality and performance, and the introduction of OSLON UV 3535 sets a new benchmark in the industry. "At 265nm, the ideal wavelength recognized as the best for killing pathogens, achieving the desired efficiency while maintaining a long service life and superior cost performance is undoubtedly a more difficult challenge."
    OSLON UV 3535 is specifically designed for UV-C disinfection solutions. With excellent performance, excellent bactericidal efficiency, long service life and outstanding cost performance, the product integrates many advantages and breaks the industry boundaries. Its compact 3.5mm x 3.5mm standard size design supports a variety of compact structures and achieves a high cumulative radiant flux over a wide emission Angle of 120°. The significant improvement in the performance of OSLON UV 3535 leds is due to innovations in package design and semiconductor technology. The product features an open 3535 ceramic package and the latest generation Algan-based flip chip technology. Compared with traditional UV-C light sources, this flip-chip light source shows more flexibility and diversity in wavelength selection, output power adjustment, and instant start function. OSLON UV 3535's open package design and integrated frame technology not only improves the performance of light sources, but also reduces manufacturing costs. Their highly reflective frame design improves the coupling output efficiency and directivity of light, making these products a strong performance advantage in the rapidly emerging UV-C market.

Advantages of UV-C LED light source
    UV-C LED technology is gradually changing the way we purify and disinfect air, surfaces and water in many application scenarios. Our carefully crafted portfolio, combined with high-performance UV-C emitters, spectral sensors and high-precision presence detection devices, ensures that UV-C illumination is applied only when and where necessary, in precisely the right dose.
    For example, at the entrance to the building, the UV-C LED reactor can be used to disinfect the water entering the building, and this process is based on actual needs. The ability to instantly turn on/off and adjust the UV-C light source is critical because the reactor must be able to respond quickly to the immediate water needs of multiple users.
    The point light source characteristics of UV-C leds enable them to produce collimated beams, thereby reducing energy loss and improving photon utilization, making them particularly suitable for air and surface treatment applications. A study carried out by the University of Liverpool strongly proves that in air treatment equipment, UV-C LED technology achieves the same system performance as traditional mercury lamps, but the amount of UV-C radiation required by the light source is much lower than the latter.
The SU CULFP1 UV-C LED in the OSLON UV 3535 series from AMS OSram is now available worldwide.
