Osram presents its first UV-C LED

News

LED technology makes extremely space-saving disinfection applications possible

Osram Opto Semiconductors has announced the Oslon UV 3636, the first product in an upcoming range of UV-C LEDs for disinfection applications.

Irradiation with UV-C light causes chemical bonds in the RNA or DNA helix of the pathogens to break down. As a result, they are no longer able to multiply and are thus rendered harmless.

A major advantage of modern, LED-based UV-C solutions is the compact size of the light sources. Thanks to their space-saving dimensions, the LEDs can be installed easily on the final application for direct interaction with the substance being sanitized such as: significantly reducing germs in faucets and disinfecting the air in air conditioning systems before it is blown into car interiors.

The direct integration of the light sources also has the advantage of ensuring that the high-energy, short-wave UV-C light does not reach the surrounding area, and therefore, does not pose a risk to people. In addition, unlike conventional lighting technologies, LEDs are very robust and insensitive to external shocks.

The Oslon UV 3636, Osram’s first UV-C LED, is available in a low- and a mid-power version and features compact dimensions of 3.6 mm x 3.6 mm. With a wavelength of 275nm, both versions are ideal for disinfection applications. The low-power version achieves 4.5 milliwatts at 30 milliamperes. The mid-power version impresses with 42 milliwatts at 350 milliamperes.

"Thanks to their compact footprint and different optical power classes, UV-C LEDs enable completely new designs and applications," explains Christian Leirer, product manager for UV-C at Osram Opto Semiconductors. "The Oslon UV 3636 is the first product in a series of innovations from Osram Opto Semiconductors in the UV-C range. A high-power UV-C LED will be launched in early 2021.”
