(1) Low UV: 250nm-265 nm -285 nm -365 nm, now it can reach 250nm-410nm. These are all INGaN/GaN material carbides. These ultraviolet rays can kill all bacteria in water, with a killing power of up to 98%, especially at 285 nm. (2) Medium ultraviolet light: 365-370 nm is an international standard for removing light, and ultraviolet light has a killing effect. Generally, doctors require surgery to ensure that there are no bacteria present. 365nm-390nm is commonly used as a UV dental supplement, characterized by strong functionality and short duration. Meanwhile, internationally, wavelengths ranging from 365nm to 370nm are used to distinguish the authenticity of banknotes. (3) High UV light: 405 nm -410 nm, with a maximum chip size of 2 inches (also known as UV chip). From 345-410nm, it can be used for the cultivation of plant seeds. It is also useful to distinguish the authenticity of RMB banknotes using 405nm-410nm.
2. VIS LED (visible light LED): (1) Blue light: 430 nm -450 nm -470 nm. Note that it should be used in the blue light band. Its main component is INGaN/GaN, but its content is low, its capacity is low, and it is not durable. It is mainly used in the 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 clearest pure green visible to the human eye in international spectroscopy. (3) Yellow light: The main application in the 570 nm -590 nm wavelength range is amber (yellow), and the main application in the 600 nm -620 nm wavelength range is orange (4). Red light: The main application in the 630 nm -640 nm wavelength range is red, and the 660 nm -730 nm wavelength range is long and mainly used in deep red. 3. Infra LED: From a medical perspective, using 660 nm -730 nm -780 nm light can promote plant growth. 730nm-760nm medical products can be used to check whether patients are vegetative. 760nm-790nm-805nm is used in medicine to detect the content of fat. 850-880 nm is used to detect the speed of the engine. 900 nm is mainly used as a testing instrument to detect human blood gas, blood sugar, etc. 940 nm is mainly used as a remote control for position locking. The detection instrument made from 1000 nm -1300 nm -1500 nm -1550 nm is mainly used to detect volatile gases such as alcohol/fiber/carbon monoxide/carbon dioxide in the human body.
