280nm LED Strip for flash pasteurization UVB wavelength coverage (275-280nm)

280nm LED Strip for flash pasteurization UVB wavelength coverage (275-280nm)

The classification of ultraviolet is UVA, UVB, UVC and UVD.Because of the shorter wavelength, UVC in the atmosphere has been absorbed by the ozone layer, scattering away, so it cannot reach the ground.The wavelength of UVB is among the three, the wavelength can only reach the skin of the skin, and the longer UVA will go deep into the skin, damage the dermis of the skin, and cause skin aging.
UVA band, with a wavelength of 320 ~ 420nm, also known as long wave dark spot effect uv.It has strong penetration and can penetrate most transparent glass and plastics.With more than 98 percent of the sun's long-wave ultraviolet rays reaching the earth's surface through the ozone layer and clouds, UVA can reach the dermis of the skin, damaging elastic fibers and collagen fibers that tan our skin.The UVA ultraviolet light with a wavelength of 360nm conforms to the photolytic response curve of insects, and can be used to make a trap lamp.UVA of the wavelength of 300-420nm can pass through the special colored glass lamp tube that is completely cut off from visible light, and only emit near-ultraviolet light with the center of 365nm, which can be used for ore identification, stage decoration, banknote inspection and other places.In October 2009, German and Italian scientists found that astaxanthin can effectively eliminate the damage of UVA to skin cells.
UVB band, wavelength 275 ~ 320nm, also known as the red spot effect uv.The shorter part of the wavelength is absorbed by the transparent glass. The medium-wave ultraviolet radiation contained in sunlight is mostly absorbed by the ozone layer.UVB rays have erythema effect on the human body, can promote the mineral metabolism and vitamin D formation in the body, but long-term or excessive irradiation will make the skin suntan, and cause redness and peeling.Uv health lamps, plant growth lamps emit a special violet glass (which does not pass through the light below 254nm) and phosphor powder with a peak of around 300nm.
UVC band, 200 ~ 275nm wavelength, also known as short wave sterilization ultraviolet.It has the least penetrating power, unable to penetrate most transparent glass and plastics.The short-wavelength ultraviolet light contained in sunlight is almost completely absorbed by the ozone layer.Short-wave ultraviolet (uvb) radiation can cause burns to the skin in a short period of time. Prolonged or intense exposure can also cause skin cancer.Uv lamp sterilization is UVC short - wave uv.
UVD band, with a wavelength of 100 ~ 200nm, also known as vacuum ultraviolet.
UVA is a terrible sunshine killer
UVA is a terrible killer of the sun. With its long wavelength and strong penetrating ability, UVA can penetrate the surface of the skin and penetrate the tissue below the dermis. It can destroy the micro-structure inside the skin such as collagen and elastic fiber tissue, generate wrinkles and fine lines, and make the skin loose and senile.This is known medically as photoaging.
In the energy distribution of ultraviolet rays in the sun, UVA is 15 times that of UVB, which is the main cause of tanning skin.It can reduce the amount of hyaluronic acid in the skin that combines water, dry the skin, accelerate melanin formation, make the skin darker, and is also an important cause of skin cancer.
The ozone layer just blocks and weakens ultraviolet light.

UVA -LED OVerview:

Uv leds generally refer to leds with the wavelength of the luminescent center below 400nm, but sometimes the luminous wavelength is greater than 380nm and is called a near-uv LED, while shorter than 300nm is called deep uv LED. Because the bactericidal effect of short wave long light is high, so ultraviolet LED is used commonly in refrigerator and household appliance and so on sterilization and deodorization etc
