(1) Low UV: 250 nm -265 nm -285 nm -365 nm, now capable of 250 nm -410 nm. these are INGaN/GaN material carbons. These UVs kill all bacteria in water up to 98%, especially at 285 nm.
(2) Medium ultraviolet light: 365 nm -370 nm go to the light are international common, ultraviolet light has the power to kill, the general doctor's surgery requirements to ensure that do not bring bacteria. 365nm-390nm generally use this ultraviolet to fill the dentist, which is characterized by: strong function, short time. At the same time, the international use of 365nm-370nm wavelengths used to identify the authenticity of banknotes.
(3) High UV: 405 nm -410 nm, with wafers up to 2 inches (also known as UV wafers). From 345-410 nm can be used for plant seed cultivation. It is also used to identify the authenticity of RMB banknotes with 405nm-410nm.
2．VIS LED (Visible LED):
（1）Blue light: 430 nm -450 nm -470 nm Note that it is applied to blue light band, its main component is INGaN/GaN, but its content is low, capacity is low, and it is not durable, and it is mainly used for blue light band.
（2）Green light: 505 nm -520 nm -540 nm is mainly used for green light band, its main component is: INGaN/GaN. 556's main component is: GaP/ALInGaP, in the international spectroscopy of its is the human eye to see the most clear pure green.
（3）Yellow light: 570 nm -590 nm band is mainly used for amber (yellow), 600 nm -620 nm band is mainly used for orange.
（4）Red light: 630 nm -640 nm band is mainly applied to the red color, 660 nm -730 nm band is long and mainly applied to the deep red color.
3．Infra LED (Infrared LEDs):
From a medical point of view, using 660 nm -730 nm -780 nm light will promote plant growth.
730nm-760nm finished medical products can check if a patient is a vegetable
760 nm-790 nm-805 nm are used in medicine for detecting fat content.
850 nm -880 nm is used to detect the rotational speed of the engine.
900 nm is mainly used as a test instrument to detect human blood gas, blood glucose, etc.
The 940 nm is mainly used as a remote control for position locking.
1000 nm -1300 nm -1500 nm -1550 nm made testing instrument mainly detects human body alcohol/fiber/carbon monoxide/ carbon dioxide and other volatile gas.
Also some special uses for special bands:
（1）250 nm -300 nm（0.1MW），350 nm -360 nm（1MW），380 nm -400 nm（5MW，20MA）。The product is inspired by 320nm~400nm band light to photocatalyst, which can effectively get rid of formaldehyde, benzene, xylene in the air in the office and viruses, bacteria and odors in the daily office air, preventing viral infections and reducing the spread of diseases. At the same time, it can also promote the body's metabolism, enhance immunity, so that we are full of energy and family health.
（2）570-580 nanometer wavelength, cause mosquito retinal blurring so that it automatically escape.
（3）320nm~380nm ultraviolet ray, can promote skin metabolism, on the skin growth force, skin thickening, but also for the treatment of psoriasis (psoriasis), vitiligo, etc.; used for illumination can be illuminated by fluorescence effect is strong; can also be used for industrial radiation detection, chemical phasing, banknote inspection.
（4）275nm ~ 320nm ultraviolet light; sunbathing on the human body's physiological role is stronger, he can cause skin photochemistry and light point process, so that the skin to produce a number of active substances, the human body's burial, mental system, endocrine system circulatory system, etc., can play a good role; the human body irradiation of sunbathing caused by the redness of the skin, resulting in redness, on the other hand, there is a skin within the 7-dehydro-ergot cholesterol is converted into vitamin D3 or D2, to promote the normal calcium and phosphorus cycle of the human body, indoor workers, pregnant women, young children and so on, is particularly important.
（5）Taking advantage of the fact that insect vision has the greatest sensitivity in the ultraviolet region near 360nm; it is possible to lure insects together and kill them.
（6）The special wavelength of 315nm, UV-B band has a strong physiological effect on animals, which can play a positive role in the normal work of the animal's burial, nervous system, endocrine system, circulatory system, and promote the synthesis of protein and vitamin D3.
