UV (Ultraviolet), that is, ultraviolet light, has a frequency of 750THz ~ 30PHz in the electromagnetic spectrum, which corresponds to the general term of radiation with a wavelength of 400nm ~ 10nm in vacuum, and cannot cause people’s vision. It is invisible light with a higher frequency than blue-violet light. The light source generated by [UVLED curing machine] is also a kind of UV light.
UV light wavelength action
1.UVLED(UVLED):
(1) Low UV: 250nm-265 nm-285 nm-365 nm, and now it has been able to do 250nm-410 nm. These are INGaN/GaN material carbides. These UVs can kill all bacteria in the water, and their lethality can reach 98%, especially 285 nm.
(2) Medium ultraviolet light: 365 nm-370 nm. Ultraviolet light is lethal, and doctors generally ask to ensure that they do not carry bacteria when operating. 365nm-390nm is generally used for dental treatment with this ultraviolet light, which is characterized by strong function and short time. At the same time, the wavelength of 365nm-370nm is used internationally to identify the authenticity of banknotes.
(3) High ultraviolet light: 405 nm-410 nm, the maximum chip is not more than 2 inches (also known as ultraviolet chip). From 345-410nm can be used for plant seed cultivation. It is also used to distinguish the authenticity of 405nm-410nm RMB banknotes.
2. VIS LED (visible light LED) :
(1) Blue light: 430 nm-450 nm-470 nm pay attention to the application of blue light band, its main component is INGaN/GaN, but its content is low, low capacity, not durable, mainly for blue light band.
(2) Green light: 505 nm-520 nm-540 nm is mainly used in the green light band, and its main component is: INGaN/GaN. The main component of 556 is: GaP/ALInGaP, which is the pure green most clearly seen by human eyes in international spectroscopy.
(3) Yellow light: 570 nm-590 nm band is mainly used as amber (yellow) 600 nm-620 nm band is mainly used as orange
(4) Red light: 630 nm-640 nm band is mainly used in red 660 nm-730 nm band length, mainly used in deep red 3 Infra LED (infrared light LED) : From a medical point of view, the use of 660 nm-730 nm-780 nm light will promote plant growth. 730nm-760nm medical products can be used to check whether the patient is vegetative 760nm-790nm-805nm is used in medicine to detect the content of fat. 850 nm -880 nm detects the engine speed. 900 nm is mainly used as an inspection instrument to detect human blood gas, blood sugar, etc. 940 nm is mainly used as a remote control for position locking. 1000nm-1300 nm-1500 nm-1550 nm detection instrument mainly detects volatile gases such as human alcohol/fiber/carbon monoxide/carbon dioxide.
Some other special uses of special bands:
(1) 250 nm-300 nm (0.1MW), 350 nm-360 nm (1MW), 380 nm-400 nm (5MW, 20MA). The product by 320nm~400nm band light excitation photocatalyst, can effectively remove formaldehyde, benzene, xylene in the air in the office and daily office air viruses, bacteria, odor, prevent virus infection, reduce the spread of disease. At the same time, it can promote metabolism in the body, enhance immunity, make us energetic and family healthy.
(2) 570-580 nm wavelength, causing the mosquito retina blur so that it automatically escape.
(3) 320nm~380nm UV, can promote skin metabolism, strong skin growth, skin thickening, can also treat moss (psoriasis), vitiligo, etc.; Used for lighting can make the fluorescent effect of the illuminated object strong; It can also be used for industrial radiation detection, chemical phase formation and banknote inspection.
(4) 275nm~320nm ultraviolet light; Sunbathing has a strong physiological effect on the human body, which can cause skin photochemistry and spot process, so that the skin produces many active substances, and can play a good role in the human body’s internal organs, mental system, endocrine system and circulatory system. Human exposure to sunbathing causes skin redness, red erythema effect, on the other hand, the 7-dehydroergot cholesterol in the skin is converted into vitamin D3 or D2, promoting the normal calcium and phosphorus cycle of the human body, especially important for indoor workers, pregnant women, children and so on.
(5) The use of insect vision has the greatest sensitivity in the ultraviolet region near 360nm; Can lure insects together and kill them
(6) The special wavelength of 315nm, the ultraviolet B band has a strong physiological effect on animals, and can play a positive role in the normal work of the animal’s internal organs, nervous system, endocrine system and circulatory system, promoting the synthesis of protein and vitamin D3.
