UV-C LEDs, which emit the wavelength with the highest sterilizing effect with a peak wavelength of 265 nm, are making a full-scale attack on the disinfection market.

ams OSRAM, a global leader in intelligent sensors and emitters, today announced the launch of its groundbreaking new UV-C LED, the OSLON® UV 3535, which addresses the growing demand for mercury-free and efficient UV-C disinfection and treatment solutions.

This single-chip product delivers a powerful 115 milliwatts of output at 265 nanometers, the most germicidal emission wavelength.

The OSLON® UV 3535 is specifically designed for UV-C disinfection solutions. It breaks boundaries by delivering superior performance, superior germicidal efficacy, long life and excellent price-performance in one package. With a standard size of 3.5mm x 3.5mm, this cutting-edge LED offers a versatile and compact design with high cumulative radiant power within a 120° emission angle.

The enhanced performance of the OSLON® UV 3535 LED is based on innovations in package design and semiconductor technology using the latest generation flip-chip in an open 3535 ceramic package. AlGaN-based flip-chip is a multi-faceted source compared to conventional UV-C sources, offering flexibility in wavelength, output, and instant-on capability. Open package design and integrated frame technology increase efficiency while reducing costs. Highly reflective frames improve light emission and forward-facing radiation, making these products strong performers in the fast-growing UV-C market.

“Advances in package design and semiconductor technology have enabled us to deliver a UV-C solution that delivers the right balance of efficiency, quality and performance,” said Nina Reiser, Senior Product Manager for UV-C at ams OSRAM. “This product sets a new industry benchmark. Achieving the desired efficacy while maintaining long lifetime and an excellent price-performance ratio at 265 nanometers – the ideal wavelength for maximum germicidal efficacy against pathogens – is not easy.”

UV-C LED technology is changing the way air, surfaces and water are purified and disinfected in a wide range of applications. ams OSRAM’s unique portfolio combines highly efficient UV-C emitters and spectral sensors with highly accurate presence detectors to ensure that the right amount of UV-C light is exposed only when needed.

For example, water can be disinfected directly from a UV-C LED reactor only when needed at the entrance of a building. Since the reactor must respond immediately to water requests from multiple users, the instant on/off and switching capabilities of the UV-C light source are essential.

The point source capability of UV-C LEDs makes them particularly effective in air and surface treatment applications because they enable a collimated beam, reducing losses and improving photon utilization. Research conducted at the University of Liverpool impressively demonstrates that UV-C LED technology can achieve the same level of system performance in air treatment units as conventional mercury lamps, but with significantly lower UV-C radiation from the light source.

The SU CULFP1 UV-C LED from ams OSRAM’s OSLON® UV 3535 family is available worldwide now. For more information on UV-C disinfection and treatment, visit https://ams-osram.com/applications/industrial/uv-c-disinfection-treatment.
