Summary and results of the test Method: UVC light is lit from the height of 5 cm/15 cm and the time required for inactivation is measured by TCID50 measuring method. Test 1: Test on the inactivation effect on SARS-CoV-2 It is expected to be used for surface sterilization and air sterilization to control new coronavirus infection, as well as for water sterilization to provide safe water. As a result, it was confirmed that the LED with 265 nm peak wavelength, which is used by our UVC LED assembly, can achieve an inactivation effect against viruses in a shorter time (about half) (Test 2). We have conducted a test to compare the inactivation effect by replacing the LED of the assembly product with an LED having 275 nm peak wavelength. This UVC LED assembly product has a high-power UVC LED with peak wavelength 265 nm. In addition, as we have confirmed that the required irradiation dose for inactivation is 4.73mJ/ cm2, customers can adjust the irradiation dose, which is indispensable in the design of a disinfection device, in accordance with the purpose.
With these properties, downsizing of the device is realized and disinfection of a wide area in a short time is achieved. Through use of our mounting technology and optical technology that were created during our history of developing LEDs, our UVC LED assembly product, which has a 265nm wavelength with a high germicidal effect and an appropriate light distribution for the target, was confirmed to have an inactivation effect of 99.9% against viruses over a wide area after only 10 seconds and 99.99% after 20 seconds when lit from a height of 5 cm. We have collaborated with Fujita Health University (School of Medicine, Associate Professor Kawamoto of Virology and Parasitology) to verify an inactivation effect on SARS-CoV-2 through use of not our single UVC LED, but our UVC LED assembly, also confirming its high inactivation effect (Test 1). The most common substances added to our lamps are iron (Fe) and gallium (Ga).Test on the inactivation effect on SARS-CoV-2 Once your chosen wavelength is agreed upon, our experts may recommend a UV-C lamp imbued with additional metal halides to achieve the optimal output. With a broad range of applications occupying different areas of the ultraviolet spectrum, it is possible to enhance certain wavelengths with the introduction of a doping element. Synthetic Quartz – Implemented to achieve the highest possible UV-C output, UV lamps fitted with synthetic quartz can reach 60% transmission at approximately 160 nm.Reaches ≥80% transmission down to approximately 210 nm. Standard Quartz – Produces ozone, useful for surface activation but requires an exhaust system.If required, our engineers can even design a tailor-made connection for you. These include our rectangular pin plug for pinch sealed lamps, and axially mounted contact pins. Alongside our standard and axially mounted ceramic connections featuring flying leads, Ushio produces various types of plug-in and axially mounted contact pins which can be selected to ensure the optimal power feed for your lamp. Connectionsĭepending on the power rating and size of the machine housing your UV emitter, you may select from our range of connections to suit all situations. The majority of Ushio lamp bases are formed from ceramic due to its excellent corrosion resistance although metal bases are available should they fit your requirements. We offer a large variety of common lamp bases, however Ushio’s UV technical development team is on standby to design bases on request for seamless integration into your existing or newly designed systems. Endless possibilities for customised base design.Quartz tube diameter variants from 13 mm to 45 mm.Any lamp length available, up to 2,500 mm.Standard flying leads, plug-in, rectangular, and axially mounted contact connections are available on request.Emitters doped with gallium, iron, etc.Standard, synthetic, or ozone-free quartz types.Pinched seals reduce unit size maintain arc length.Simultaneous power connection and secure mounting.
