科学者たちは、｢紫外線が多くのウイルスやバクテリアを滅菌すること｣を、周知しています。
Solid State Lighting/Energy Electronics Centerの研究者は、その研究に特化。
UVスペクトル：発光ダイオード
UVスペクトルの発光ダイオードで、｢COVID-19ウイルスで汚染された表面を、消毒できる｣研究を報告しています。
UVスペクトル：
- 電磁波は多くの波長で構成されています。
- AMまたはFM：無線通信に使用されるもの、
- 他の電磁波；電子レンジで食品を調理するため、
The human eye reacts to some electromagnetic wavelengths, which allows us to see the world around us.
The visible spectrum ：ranges from red to violet.
Any wavelengths longer than red are called infrared
— below red. Any wavelengths shorter than violet are called ultraviolet —
above violet. None of this has anything to do with the bands Deep Purple or Purple Haze.
Got that? Let’s move on.
Killing Virus With Light
While some scientists rush to discover a vaccine that is effective against the COVID-19 virus,
others are working to discover new ways to sanitize areas that may have the virus on their surfaces.
Wiping door handles and light switches with disinfectant is all very good,
but how do you reach deep into ventilating systems where the virus could be hiding?
Ultraviolet LEDs could be one solution.
Christian Zollner, a doctoral candidate at UC Santa Barbara says,
“One major application is in medical situations — the disinfection of personal protective equipment, surfaces, floors, within the HVAC systems, et cetera.”
The work at UC-SB is supported by many corporate partners.
One of them：Seoul Semiconductor,
which reported last week a “99.9% sterilization of coronavirus (COVID-19) in 30 seconds” with its UV LED products.
The technology currently is used to make UV LED lamps that sterilize the interior of unoccupied vehicles.
What we call ultraviolet
is actually three different segments of the EM spectrum.
UV-A and UV-B are the ones commonly supplied to the Earth by the sun.
UV-C is the most effective as a disinfectant but does not occur in nature. It has to be created by humans.
