Product Introduction:
220nm 222nm 254nm UVC SMD LED Chip 1W sterilization is using special Japan brand crystals to reach deep UVC wavelength 220-225nm.
As far as the reports shows, 220nm and 222nm uvc wavelength has no harmful effect to our human beings skins.
We can expose ourself under the 220nm 222nm uvc wavelength without any protection.
It is safer uvc wavelength compared with other uvc wavelength, for more details, please write back to us directly.
Attention: 220nm and 222nm crystals are bought from Japan. Its crystals source is not stable. Sometimes we can not get the crystals for nearly 2-4 months.
And also its price is higher 500-1000% compared with normal 265-280nm uvc smd leds, so we do not suggest our clients to use it for commercial purpose. Because its finished sterilization product cost is too high. The end clients can not even afford to buy it.

220nm 222nm 254nm UVC SMD LED Chip 1W sterilization technical specs:
220nm 222nm 254nm UVC SMD LED Chip 1W sterilization application:
220nm 222nm 254nm UVC SMD LED Chip 1W sterilization is mainly used for making the sterilization & germicidal & disinfection device. It is popular and more and more clients want to use such product in the Covid-19 pandemic period.
Some knowledge about 220nm 222nm 254nm UVC SMD LED Chip 1W sterilization:
222nm UVC ultraviolet lamp can sterilize and harm the human body?
According to news in April this year, a joint study by Kobe University in Japan and Ushio, a Japanese LED component manufacturer, showed that repeated exposure to filtered 222 nm UVC light in hairless mice with particularly sensitive skin did not cause their Get skin cancer or cataracts. From this, it is proposed that deep ultraviolet radiation with a wavelength of 222 nm is harmless to human skin and eyes.
Similarly, Columbia University in the United States has also carried out related research. Preliminary results show that far UVC with a wavelength of 222nm cannot penetrate the skin surface or eyes, is safe for the human body, and can kill viruses.
According to reports, Ushio and a research team from Kobe University's Department of Plastic Surgery have completed a study showing that irradiating human skin with filtered 222nm UVC light can reduce the number of bacteria on human skin without causing damage to the skin.
This study used Oxtail's Care222® UV-C disinfection device with a wavelength of 222 m and a radiant energy of 500 mJ/cm2, including an optical filter. This short bandpass filter is based on research and technology from Columbia University and has been patented to filter radiation at wavelengths above 230nm.
But unfiltered 222 nm UV-C lamps, if not properly filtered, these devices can pose a serious threat to human health. The 222 nm outside line lamps currently on the market are not monospectral. "222 nm" refers only to the peak wavelength, other wavelengths are emitted, many are harmful. Without filtering, even a 222nm UV lamp is dangerous as this lamp produces light up to 320 nm! To be clear: the UV-C "safe zone" is between 200 nm and 230 nm. At present, there are still many disputes in the industry that UVC light can kill coronavirus and that UVC light with a wavelength of 222nm is harmless to the human body. There is a lot of attention from all walks of life, and more and more detailed studies are expected to prove these results.
