LED lighting special use different bands

  1. UVLED (UV-LED):

(A) low UV: 250nm-265 nm -285 nm -365 nm, has now been able to do 250 nm -410 nm. These are INGaN / GaN material carbide. These UV can kill all bacteria in water, its lethality of up to 98%, especially 285 nm.

(2) in the UV: 365 nm -370 nm to go according to all international general, UV lethal, surgery requires general practitioners to ensure that without bacteria. 365nm-390nm UV generally use this to fill the dentist, its features are: strong function, time is short. Meanwhile, the international community is used to identify the authenticity of banknotes with a wavelength of 365nm-370nm.

(3) High UV: 405 nm -410 nm, the maximum chip no more than 2 inches (also known as ultraviolet wafer). From 345-410nm can be used to plant seeds cultivated. 405nm-410nm is also useful for identifying the authenticity of renminbi banknotes.

  2. VIS LED (visible LED):

(1) Blu-ray: 430 nm -450 nm -470 nm attention applied to blue band, whose main ingredient is INGaN / GaN, but its content is low, low capacity, not durable, mainly for blue band.

(2) Green: 505 nm -520 nm -540 nm is mainly used for the green band, the main component: INGaN / GaN. 556 is the main ingredient: GaP / ALInGaP, in the international spectroscopy is one of its most clearly seeing pure green.

(3) yellow: 570 nm -590 nm band is mainly applied to amber (yellow)

600 nm -620 nm band is mainly applied to orange

(4) Red: 630 nm -640 nm band is mainly applied to red, 660 nm -730 nm wavelength long, the main application of crimson.

  3. Infra LED (infrared LED):

From a medical point of view, with a 660 nm -730 nm -780 nm light will promote plant growth.

730nm-760nm is made of medical product can check whether the patient is in a vegetative state.

760 nm-790nm-805nm is used for detecting the fat content of the medicine.

850 nm -880 nm for detecting the rotational speed of the engine.

900 nm is mainly made of test instrument for detection of human blood and blood sugar.

940 nm is mainly made on the remote control for a position fix.

1000 nm -1300 nm -1500 nm -1550 nm made ??instrumentation to detect volatile gas main body of alcohol / fiber / carbon monoxide / carbon dioxide.

 Also some special band special purpose:

(1) 250 nm -300 nm (0.1MW), 350 nm -360 nm (1MW), 380 nm -400 nm (5MW, 20MA). The product consists of 320nm ~ 400nm wavelength excitation 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 they can promote metabolism, enhance immunity, let us energetic, family health.

(2) 570-580 nanometer wavelength, causing mosquitoes retinal blur it automatically flee.

(3) 320nm ~ 380nm ultraviolet light, can promote skin metabolism, and strong growth on the skin, skin thickening, but also the treatment of psoriasis (psoriasis), vitiligo, etc.; used for lighting can be intense fluorescence lighting effects; also can be used for industrial radiation detection, chemical composition phase, paper money.

(4) 275nm ~ 320nm UV; sunbathing physiological effects on the human body is strong, he can cause skin and spot photochemical process, the skin produces a lot of active substances on the human body’s internal organs, the spirit of the system, the endocrine system, circulatory system can play good effect; human exposure after sunbathing cause skin redness, erythema effect, on the other hand there are 7-dehydrogenation ergot cholesterol in the skin into vitamin D3 or D2, promote the body’s normal calcium and phosphorus cycling, indoor staff, pregnant women, children and other particularly important.

(5) at 360nm using the near vision of insects having a maximum sensitivity in the ultraviolet region characteristic; able to kill the insect attractant together.

(6) 315nm wavelength specific physiological role of UV-B band stronger animals, animal offal, normal working of the nervous system, endocrine system, circulatory system, can play a positive role in promoting the synthesis of protein and vitamin D3.
