In the future, UVLED nail phototherapy lamp should be expected in the application market of nail industry.
Medical ultraviolet phototherapy
The wavelength range of ultraviolet phototherapy is 275nm-320nm. Its principle is that light energy causes a series of chemical reactions, which have the effects of anti-inflammatory, analgesic and anti rickets. It is commonly used to treat skin suppurative inflammation and other dermatitis, pain syndrome, rickets or chondropathy.
Among them, the ultraviolet with the wavelength in the range of 310-313nm is called narrow spectrum ultraviolet B (NBUVB) , it focuses on the part with the strongest biological activity in ultraviolet rays, which directly acts on the affected part of the skin, and filters out the bad band ultraviolet rays harmful to the skin. It has the characteristics of small side effects, acting on the cuticle of the skin, short onset time and quick effect. It has become one of the most popular research topics, especially the phototherapy instrument with LED as the light source, which is a research hotspot in the medical field at present. LED has With the characteristics of high efficiency, low power consumption, less heat production, long service life and green environmental protection, it is widely used as an efficient and safe light source in the field of phototherapy.
Ultraviolet communication
Ultraviolet communication is a wireless optical communication technology based on atmospheric scattering and absorption. Its basic principle is to take the spectrum of the solar blind area as the carrier, modulate and load the information electrical signal on the ultraviolet carrier at the transmitting end, the modulated ultraviolet carrier signal propagates by atmospheric scattering, and establish an optical communication link at the receiving end by capturing and tracking the ultraviolet beam The information signal is extracted by photoelectric conversion and demodulation processing.
The scattering of ultraviolet light in the atmosphere changes the energy transmission direction of ultraviolet light, which lays a communication foundation for ultraviolet communication, but the attenuation brought by absorption limits the transmission of ultraviolet light within a certain distance. Ultraviolet communication is a wireless optical communication technology based on atmospheric scattering and absorption.
UV communication is especially suitable for short-range anti-interference and secure communication in complex environment. At present, UV-LED has been realized to realize short-range signal scattering transmission. In practical communication applications, UV-LED can be composed of array structure to increase the transmission distance of UV communication by increasing the transmission power.
Deep UV LED water purification
The wavelength range of deep UV LED water purification is 220nm-285nm. Its sterilization principle is to destroy the DNA structure of microorganisms and make bacteria die or unable to reproduce, so as to achieve the purpose of sterilization. It is pure physical disinfection, non-toxic, no residue, no odor, very simple and efficient, so it has a wide range of applications. With the impact of the original epidemic situation on the public, the public's health awareness in daily life is increasing , in the future, surface / air sterilization and purification, static water sterilization and flowing water sterilization will be deep UV LED.
Photolysis oxidation fume purification technology
The principle of photolysis oxidation oil fume purification technology is to cut off the oil molecular chain by using 185nm special ultraviolet lamp to form small oil molecules. At the same time, 185nm special ultraviolet light reacts with oxygen in the air to produce ozone. Ozone oxidizes small oil molecules to produce water, carbon dioxide and trace white powder. At the same time, the organic matter in the oil fume is photolysis oxidized, and the peculiar smell in the flue is also reduced Then it will be eliminated, and the pollution-free emission will be achieved in the way of "treating the symptoms and root causes".
