About This Product
Sigaine, an air purifier equipped with deep UV LEDs, is an air purifier for 9 tatami mats that is effective in inactivating mold and viruses using deep UV LEDs. In addition, it uses a high-performance filter to efficiently remove PM2.5, pollen, and dust.
The technical term for ultraviolet radiation is ultraviolet radiation, and the abbreviation ``UV'' is widely used. The terms ultraviolet wavelength and ultraviolet irradiation are synonymous. Ultraviolet (UV) light has a shorter wavelength than visible light (approximately 380nm purple to 780nm red) and is invisible to the naked eye. The bluish-white light from an ultraviolet lamp is visible light, which is mixed with invisible ultraviolet light.
Depending on the length of its wavelength (unit: nm = nano meter / nano = one billionth),
UV-A (400nm-315nm)
UV-B (315nm~280nm)
UV-C (280nm~200nm)
is generally classified as.
Common ultraviolet rays are called "near ultraviolet rays," and they sometimes refer to wavelengths up to 380 nm instead of 400 nm. In addition, wavelengths such as 185nm and 172nm, which are often used in UV technology, are not included in the above A, B, and C classifications, so when using UV technically, it is necessary to use the UV-A, B, and C classifications. Rather, irradiation is performed by selecting a specific UV wavelength depending on the application and purpose of irradiation, and selecting a lamp/light source that generates that specific UV wavelength.
■Uses/purposes of irradiation and examples of specific ultraviolet wavelengths
・Curing of UV resin/UV paint: 200-400nm wavelength, mainly 365nm is used
・UV cleaning, UV sterilization, etc.: Mainly 254nm wavelength (185nm, which generates ozone, may also be used)
■Ultraviolet wavelength and types of lamps used in ultraviolet irradiation equipment
The light source lamps used for ultraviolet irradiation in industrial technology are generally as follows:
High pressure mercury UV lamp: (quartz glass) Main wavelength: 365nm, wavelength UV irradiation device
It is mainly used for curing and drying UV curing resins and UV paints, and for dicing and peeling.
Metal halide UV lamp: (quartz glass) Ultraviolet irradiation device with a continuous wavelength of 200 to 400 nm
Used for curing UV paints that are sensitive to ultraviolet rays with wavelengths other than 365 nm.
