Why big coffee collective layout UV LED?

With the deepening of LED research and development, LED technology innovation and application fields continue to expand, LED market is also more and more broad. UV LED gradually into our vision, and there are some companies involved in research, improvement, application of UV LED UV lamp. For the general public, the right amount of wavelength of UV light is also necessary for our body. So we come to know what the main application of UV LED in the field.

The so-called ultraviolet (Ultraviolet Rays/ UV) refers to the sun light in the visible light (red orange yellow green blue purple, purple) outside the invisible light. Ultraviolet radiation is the general term for the wavelength from 10nm to 400nm. According to the different wavelength, generally divided into ultraviolet A, B, C three bands, as follows: UVA is 400 ~ 315 nm, UVB is from 315 to 280 nm, UVC is from 280 to 100 nm. Corresponding to different wavelengths, different applications.

In the UVLED market applications, UV-A has the largest market share, up to 90%. Its main application market for curing, related to nail, teeth, ink printing and other fields. In addition, UV-A also introduced commercial lighting, can make white clothes look more white. As for UV-B and UV-C is mainly used in sterilization, disinfection, medical light therapy, UV-B, which is mainly based on medical treatment, UV-C sterilization. In addition, UV LED from bill recognition, applied to optical resin hardening, trapping, printing, and sterilization and disinfection in market development, Bio Medical, security identification, air purification, data storage and military aviation, with special lighting.

1 Application of UV curing system

The typical application of UVA band for UV curing and UV inkjet printing, representing the wavelength of 395nm, 365nm, UV, LED light curing applications included in the display, medical electronics, instrumentation and other industries UV adhesive curing; building materials, furniture, household appliances, automotive and other industries curing; UV ink curing printing, packaging and other industries...... Among them, the UV LED decorative panel industry has become a hot spot, the biggest advantage is the production of zero formaldehyde environmental protection plate, and energy saving 90%, large output, scratch resistant coins, comprehensive economic benefits. This indicates that the UV LED curing market is a full and full range of application products market.

The application of -UV light curing microelectronics industry: mobile phone components (camera, earphone, microphone, shell, LCD module, touch screen coating, etc.) hard disk assembly (wire fixed bearing, coil, chip bonding etc.), DVD/ (digital camera lens, lens bonding, circuit board reinforcement, and element assembly (motor) wire, coil fixed, fixed coil ends, PTC/NTC element bonding, protection of transformer core), semiconductor chip (moisture proof protective coating, wafer and mask, wafer contamination test, UV exposure tape, wafer polishing, sensor production (check) gas sensor, photoelectric sensor, optical fiber sensor, photoelectric encoder).

LEDUV light curing industry: application of PCB component (capacitance, inductance, various plug, screw, chip etc.) fixed, encapsulating and core circuit, chip moisture protection, anti-oxidation protection, circuit board type (angle) coating, wire coil fixing, fly line, wave soldering through hole mask.

2 medical field

Skin treatment: UVB band is an important application of skin treatment, that is, the use of ultraviolet light therapy. The scientists found that UV wavelength around 310nm has strong shading effect to the skin, the skin can accelerate the growth of the skin to improve the The new supersedes the old., force, which can be useful for the treatment of vitiligo, pityriasis rosea, polymorphous light eruption and chronic actinic dermatitis, itchy rash actinic light skin disease, so in the medical industry, purple at present, foreign phototherapy has been used more and more. Compared with the traditional light source, the UV-LED line is pure, which can guarantee the maximum therapeutic effect. UVB band can also be used in the field of health care, after UVB band irradiation can induce photochemical human body and photoelectric response, make the skin produce various bioactive substances, has been used in regulation of advanced nerve function, improve sleep, reduce blood pressure etc.. In addition, studies have shown that UVB band can accelerate the production of polyphenols in some leafy vegetables, such as red lettuce, which are claimed to have anti-cancer, anti-cancer and anti cancer mutations.

Medical devices: UV glue bonding makes it easier for medical devices to automate the economy. Now, LED UV light source system is advanced, can a few seconds without solvent UV curing glue, and dispensing systems, the medical device assembly process method of forming an adhesive consistent and repeatability of an effective and economical. The optimization and control of UV light source is very important for the manufacture of reliable medical devices. The use of UV curable glue offers a number of advantages, such as lower energy requirements, saving curing time and location, improved productivity, and easier automation. UV glue is commonly used for bonding and sealing medical devices, which require very high quality and best reliability. UV glue curing typically used in medical device assembly, such as the need to bond 1) different materials (or mechanical properties are not the same) 2) material is not thick enough, can not be used welding method 3) pre production of sub parts.

3 sterilization field

UVC band of ultraviolet light due to the length of the wave, high energy, in a short period of time to destroy the microbial body (bacteria, viruses, spores and other pathogens)
