Special use of LEDs in different bands


(1) Low UV: 250nm-265 nm -285 nm -365 nm, now 250 nm -410 nm. These are all carbides of INGaN/GaN materials. These UVs kill all bacteria in the water with a killing power of 98%, especially at 285 nm.

(2) Medium-ultraviolet light: 365 nm - 370 nm is common internationally, and ultraviolet light has lethality. Generally, doctors are required to ensure that no bacteria are required during surgery. 365nm-390nm generally uses this ultraviolet to supplement the dentist, which is characterized by strong function and short time. At the same time, the wavelength of 365nm-370nm is used internationally to distinguish the authenticity of banknotes.

(3) High-ultraviolet light: 405 nm -410 nm, the maximum wafer size is less than 2 inches (also known as UV wafer). From 345-410 nm can be used for the cultivation of plant seeds. It also uses 405nm-410nm for the authenticity of RMB banknotes.
2. VIS LED (visible LED):

(1) Blue light: 430 nm -450 nm -470 nm Note that it is applied to the blue light band. Its main component is INGaN/GaN, but its content is low, its capacity is low, and it is not durable, mainly used in the blue light band.

(2) Green light: 505 nm - 520 nm - 540 nm is mainly used for the green light band, and its main component is: INGaN/GaN. The main component of 556 is: GaP/ALInGaP, which is the purest green that is most clearly seen by the human eye in international spectroscopy.

(3) Yellow light: The main application of the 570 nm -590 nm band is amber (yellow)

The main application of the 600 nm -620 nm band is orange.

(4) Red light: The main application of the 630 nm - 640 nm band is red, and the 660 nm -730 nm band is long, and the main application is dark red.

3. Infra LED (infrared LED):

From a medical point of view, using 660 nm -730 nm -780 nm light promotes plant growth.

730nm-760nm made of medical products can check whether the patient is a vegetative

760 nm - 790 nm - 805 nm is used in medicine to detect fat content.

The 850 nm -880 nm is used to detect the speed of the engine.

900 nm is mainly used as an inspection instrument to detect blood gas, blood sugar, etc.

The 940 nm is mainly used as a remote control for position locking.

1000 nm -1300 nm -1500 nm -1550 nm is a test instrument that mainly detects volatile gases such as alcohol/fiber/carbon monoxide/carbon dioxide.

Special uses for other special bands:

(1) 250 nm - 300 nm (0.1 MW), 350 nm - 360 nm (1 MW), 380 nm - 400 nm (5 MW, 20 MA). The product is excited by photo-catalyst from 320nm to 400nm. It can effectively eliminate formaldehyde, benzene, xylene and viruses, bacteria and odors in the air of office, prevent virus infection and reduce disease transmission. At the same time, it can promote metabolism and enhance immunity in the body, so that we can be energetic and healthy.

(2) 570-580 nm wavelength, causing the mosquito retina to blur and let it escape automatically.

(3) 320nm ~ 380nm ultraviolet light, can promote skin metabolism, strong skin growth, thick skin, can also treat psoriasis (psoriasis), vitiligo, etc.; used for illumination can make the illumination of the object is strong; Can be used for industrial radiation detection, chemical phase formation, banknote verification.

(4) 275nm~320nm ultraviolet light; sunbathing has a strong physiological effect on the human body. He can cause skin photochemistry and light spot process, which causes the skin to produce many active substances, which can play a role in the human internal organs, mental system and endocrine system circulatory system. Good effect; the human body causes redness of the skin after sunbathing, and produces erythema effect. On the other hand, it converts 7-dehydro ergot cholesterol in the skin into vitamin D3 or D2, which promotes the normal calcium and phosphorus circulation of the human body, to indoor workers, Pregnant women, young children, etc. are especially important.

(5) Using the insect's visual acuity to have the highest sensitivity in the ultraviolet region around 360 nm; capable of attracting insects together and killing them

(6) The special wavelength of 315nm, the ultraviolet B-band has strong physiological effects on animals, and can play an active role in the normal work of the internal organs, nervous system, endocrine system and circulatory system of animals, and promote the synthesis of protein and vitamin D3.

Safety: unlike glass neon tube, its normal operation requires a high voltage of 15,000V, while the flexible neon strip is at 12V. And its shockproof, temperature resistant, salt resistant, acid and alkali resistant.
