• Outstanding output power and wall plug efficiency (WPE): typically 115mW at 5.3%
• Maximized germicidal effectiveness: peak emission wavelength at 265nm
• Compact and durable design: superior R70B50 lifetime of more than 20,000 hours

Premstaetten, Austria, and Munich, Germany (October 23, 2024) – ams OSRAM (SIX: AMS), a global leader in intelligent emitters and sensors, has unveiled its new OSLON® UV 3535. This groundbreaking UV-C LED serves the growing demand for mercury-free and efficient UV-C disinfection and treatment solutions. It offers powerful 115 milliwatts out of a single chip at 265 nanometers, which is the emission wavelength providing the highest germicidal effectiveness. Combined with outstanding wall plug efficiency, this optimized system solution has been specifically designed for customers in the UV-C disinfection market.

“Our advancements in package design and semiconductor technology are leading the way in UV-C solutions that blend efficiency with quality and performance,” stated Nina Reiser, Senior Product Manager for UV-C at ams OSRAM. “This product sets a new industry benchmark. Meeting the efficiencies desired while maintaining a long lifetime and superior price performance becomes more challenging at 265 nanometers, the ideal wavelength to achieve the maximum germicidal effectiveness to fight pathogens”.

The OSLON® UV 3535 is specifically engineered for UV-C disinfection solutions. The product pushes the boundaries by delivering outstanding performance, the highest germicidal effectiveness, a long lifetime and superior price performance: all in one product! With a standard 3.5mm x 3.5mm footprint, these top-notch LED supports versatile, compact designs with high cumulative radiant flux within a 120° emission angle. The enhanced performance of the OSLON® UV 3535 LEDs is attributed to innovations in package design and semiconductor technology using the latest flip-chip generation in an open 3535 ceramic package. The AlGaN-based flip chip is a more multifaceted radiation source than traditional UV-C sources, offering flexibility in wavelength, output power and instant-on functionality. Its open package design and integrated frame technology increase efficiency while reducing costs. The highly reflective frame improves light outcoupling and forward-directed radiation, positioning these products on a strong performance trajectory in the rapidly growing UV-C market.

The advantages of UV-C LED sources
UV-C LED technology is changing the way we purify and disinfect air, surfaces and water in a variety of applications. Our unique portfolio combines highly efficient UV-C emitters and spectral sensors with highly accurate presence detectors, ensuring exposure to UV-C light at the right doses only when and where required.

To cite just one example: water can be disinfected in a UV-C LED reactor directly at the entry point to a building and only if needed. Instant on/off and switching capability of the UV-C source are essential as the reactor must respond immediately to the water requests of several users.

The point source feature of UV-C LEDs enables collimated beams, reducing losses and enhancing photon utilization, thus making them particularly effective for air and surface treatment applications. A study conducted by the University of Liverpool impressively demonstrated that UV-C LED technology achieves the same level of system performance as traditional mercury lamps in air treatment devices but requires significantly lower UV-C radiation from the source.
