1.(UV LED):
(1) Low UV: 250nm-265 nm -285 nm -365 nm, we are now able to do 250 nm -410 nm. These are INGaN / GaN material carbide. These UV can kill all bacteria in water, its lethality up to 98%, particularly 285 nm.
(2) ultraviolet light: 365 nm -370 nm according to all internationally accepted, UV lethal, surgery requires general practitioners to ensure that without bacteria. 365nm-390nm UV is generally used to fill the dentist, which is characterized by: strong function, time is short. At the same time, the international community used to identify the authenticity of banknotes with a wavelength of 365nm-370nm.
(3) High UV: 405 nm -410 nm, the maximum wafer is less than 2 inches (also known as ultraviolet wafer). From 345-410nm may be used for seed cultivation. Also useful 405nm-410nm is used to identify the authenticity of RMB banknotes.
2. (Visible LED):
(1) Blu-ray: 430 nm -450 nm -470 nm note applies to blue band, whose main ingredient is INGaN / GaN, but its content is low, low capacity, not durable, mainly used for the blue band.
(2) Green: 505 nm -520 nm -540 nm is mainly used for the green band, the main component: INGaN / GaN. The main component is the 556: GaP / ALInGaP, spectroscopy in the international human eye which is most clearly pure green.
(3) yellow light: 570 nm -590 nm band is mainly applied as amber (yellow)
600 nm -620 nm band of the main application as an orange
(4) Red: 630 nm -640 nm band is mainly applied to red, 660 nm -730 nm band length, the main application for the deep red.
3.(infrared LED):
From a medical point of view, using the 660 nm -730 nm -780 nm light promotes plant growth.
730nm-760nm of the finished product can be made medical check whether the patient is in a vegetative state
760 nm-790nm-805nm is used for detecting the content of fat in medicine.
850 nm -880 nm for detecting the engine speed.
900 nm is mainly made of testing equipment for the detection of human blood and blood sugar
940 nm is mainly made remote controller for a position fix.
1000 nm -1300 nm -1500 nm -1550 nm detection instrument is mainly made of highly volatile gases detected human alcohol / fiber / carbon monoxide / carbon dioxide.
Also some special bands for special purposes:
(1) 250 nm -300 nm (0.1MW), 350 nm -360 nm (1MW), 380 nm -400 nm (5MW, 20MA). The product consists of 320nm ~ 400nm excitation band light photocatalyst, can effectively eliminate the office air formaldehyde, benzene, xylene and daily office airborne viruses, bacteria, odors, prevent transmission of the virus and reduce the spread of disease. At the same time it can promote metabolism, enhance immunity, let's energetic, healthy family.
(2) 570-580 nm wavelength, causing mosquito retinal blur it automatically escape.
(3) 320nm ~ 380nm UV can promote skin metabolism, strong growth on the skin, skin thickening, but also the treatment of psoriasis (psoriasis), vitiligo, etc; can be used to illuminate a strong fluorescence lighting effects; also It is used for industrial radiation detection, chemical composition phase, paper money.
(4) 275nm ~ 320nm UV; solarium physiological effects on the human body is strong, he can cause skin and spot photochemical process, so that the skin to produce a lot of active substances on the human body organs, nervous system, endocrine system, circulatory system can play good effect; after sun body irradiation caused skin redness, erythema effect, on the other hand there are 7-dehydrogenation of cholesterol in the skin ergot converted to vitamin D3 or D2, promote the body's normal calcium and phosphorus cycle, the staff the room, pregnant women, children and other particularly important.
(5) the use of 360nm in insect vision near ultraviolet region has the greatest sensitivity characteristics; be able to kill the insect attractant together
(6) 315nm wavelength specific physiological effects of UV-B on animals stronger, animal offal, normal operation of the nervous system, endocrine system, circulatory system, can play a positive role in promoting the synthesis of protein and vitamin D3.
