Various directions for the use of deep UV LEDs
An epidemic, so deep UVC LED germicidal lamps from professional places into the public eye. Entrepreneurs with a keen sense of smell have been turned on full throttle, the launch of new deep UVC germicidal lamps to grab market share. With the refinement of technology, market expansion and industrial development, making the market outlook for UV LEDs increasingly broad.
UV-LED refers to the light-emitting center wavelength below 400nm LED, so in addition to common germicidal lamps, deep UV-LED can also be used in what areas?
According to relevant data, the global UV-LED market from 2018-2023 compound growth rate of 27%, the next five years is expected to reach 100 billion domestic deep UV LED germicidal disinfection application market size. In addition to the steady growth of the curing market, surface / air sterilization and purification, static water sterilization, flowing water sterilization for the future of the main growth momentum.
I. UV curing light source
UV curing technology wavelength range of 320nm-400nm, is through the UV irradiation of organic coatings, so that the radiation cross-linking reaction, the relative molecular mass of the low material cured into the relative molecular mass of the high material of the chemical process.
For example, UV glue in the production industry is widely used to UV LED curing light source to bring the market, Apple (Apple) use UV glue coating to protect the sensing element from ultraviolet light, and the use of UV LED to replace the traditional UV mercury lamp as a curing light source, led by Apple to promote the rapid growth of UV LED market applications; in the printing ink curing process, the photochemical reaction The actual absorption wavelength is about 350 to 370nm between the use of UV-LED can be better achieved.
Another neglected nail market, there is a broader market application for UV-LED nail curing lights. According to relevant studies, China's per capita annual consumption of nail is 10.7 times, nail products and nail services are becoming a rapidly developing economic growth point in the beauty industry. With the rapid growth in the number of nail salons nationwide, UV-LED nail curing lamp products are hot, with its energy-saving, environmentally friendly, safe and portable, fast response time, short curing time and other advantages are widely replacing the traditional mercury nail curing lamp. Future UV-LED nail therapy lights in the nail industry applications market is worth looking forward to.
Second, medical-type ultraviolet light therapy
The wavelength range of ultraviolet light therapy in 275nm-320nm, the principle of light energy to cause a series of chemical reactions, anti-inflammatory, analgesic, anti-rickets effect, commonly used to treat septic inflammation of the skin and other dermatitis, pain syndrome, rickets or chondromalacia, etc..
Among them, the ultraviolet ray in the wavelength range of 310-313nm is called narrow-spectrum medium-wave ultraviolet (NBUVB), which concentrates the most biologically active part of the ultraviolet ray to act directly on the affected area of the skin, while filtering out the undesirable band of ultraviolet rays harmful to the skin, with small side effects, acting on the corneal layer of the skin, short onset time and quick effect, and other characteristics, becoming the most popular LEDs have the characteristics of high efficiency, low power consumption, low heat generation, long life span, green and environmental protection, and are widely used as an efficient and safe light source in the field of phototherapy.
III. Ultraviolet communication
Ultraviolet communication is a wireless optical communication technology based on atmospheric scattering and absorption. Its basic principle is to use the spectrum of the sun blind area as the carrier, in the transmitter side of the information electrical signal modulation loaded to the UV carrier, has modulated the UV carrier signal using atmospheric scattering effect for propagation, in the receiver side through the capture and tracking of the UV beam to establish an optical communication link, by photoelectric conversion and demodulation processing to extract the information signal.
The scattering effect of UV light in the atmosphere makes the direction of energy transmission of UV light change, which lays the foundation of communication for UV light communication, but the attenuation brought by the absorption effect makes the transmission of UV light limited to a certain distance. Ultraviolet communication is a wireless optical communication technology based on atmospheric scattering and absorption.
UV-optical communication is particularly suitable for close range anti-jamming confidential communication in complex environments. At present, UV-LEDs have been realized to achieve short-range signal scattering transmission, and in practical communication applications, UV-LEDs can be formed into an array structure to increase the transmission distance of UV communication by increasing the transmitting power.
Four, deep ultraviolet LED water purification
Deep ultraviolet LED water purification wavelength range in 200nm-280nm, its sterilization principle is to destroy the DNA structure of microorganisms, so that bacteria die or can not reproduce, so as to achieve sterilization purposes, pure physical disinfection, non-toxic residue-free odorless, very simple and efficient so wide application areas. With the impact of the original epidemic to the public, the public's health awareness in daily life is increasing, the future, surface / air sterilization and purification, static water sterilization, flowing water sterilization for deep UV LED.
The public has a new understanding of public and home health, can see the future potential and development prospects of the deep ultraviolet LED market, to live a healthy theme of deep ultraviolet LED products will become the mainstream of the market promotion object.
