It is a truly sustainable green industrial technology. In recent years, UVLED curing technology has attracted great attention from the world. In many applications, UVLED light sources have gradually replaced traditional mercury light sources. UVLED is a kind of electrical light emitting diode. Compared with the traditional UV mercury lamp, it is more environmentally friendly, efficient and low -energy consumption. It is a truly sustainable green industrial technology. UVLED characteristic single wavelength, high light emitting efficiency, low energy consumption UVLED can directly convert electrical energy to UV light, and send out the ultraviolet light of single -wave bands, the light energy is highly concentrated in specific ultraviolet light bands. Now there are mature applications in the market. 365nm, 385nm, 395nm, 405nm two bands. The launch spectrum of traditional UV mercury lamps is very wide, and the ultraviolet spectrum segment that truly solidified only accounts for only part of it. At the same time. Do not produce infrared and ozone traditional mercury lamps to generate infrared rays, and emit a lot of heat, which can cause damage to thermal sensitive substrate. UVLED is a cold light source, which can effectively avoid contraction and deformation due to overheating of substrates. UVLED, which is also used for ultraviolet curing, is usually UV light with long wavelengths, so it does not produce ozone during the curing process. It can maintain a good working environment. That is to light up, the electronic control UVLED does not need to warm up like mercury lamps, nor does it need to keep the lamp in order to maintain the life and work efficiency of the lamp. UVLED can turn on (off) light instantly, the output energy can also be set freely, and can be automatically adjusted with the speed of the machine. It is very energy -saving and easy to control. The service life is long, and the use of low LEDUV lights for maintenance costs can reach more than 10,000 to 50,000 hours, which is more than 10 times the traditional mercury lamp, and the light atmosphere is very slow. The service life is not affected by the number of switches. At the same time, the LED light source has no mercury, and there is no attachments such as lampshade, so there is almost no need to maintain, reducing the maintenance cost. High flexibility, small LED light sources in the system size can be divided into point light sources, wire light sources, and surface light sources. The size of the light source equipment is small, and the irradiation device is very compact to related supporting devices. It does not require the larger mechanical installation space and pipeline construction in the past. This characteristic makes it adapt to various production processes, and the production process is more efficient. From 2011 to 2016, the sales of UVLED and traditional UV mercury lamp equipment UVLED market and prospects. According to Technavio, the UVLED market has maintained a very high-speed growth in the past seven or eight years. From 2008 in 2008 to 2014 90 million US dollars, the average annual growth rate of the compound is as high as 28.5%. In 2016, due to the actively imported applications such as photosynthesis, sterilization and purification markets, the estimated output value will be US $ 166 million, of which the output value of LEDs will reach $ 81 million in the optical curing market. By 2020, the average annual growth rate of the global UVLED technology market will reach 39%. In 2015, the ultraviolet optical curing market accounted for 48.14% of the UVLED technology market. The demand for UVLED curing devices in the printing industry has increased, and the significant improvement of the general volume density for UVLED chips has made UV curing occupy a large part of the UVLED technology market. At the same time, the printing industry has developed into a large user of LED curing equipment. UVLED technology has achieved great success in the field of inkjet, and has promoted the application of UVLED technology in the entire printing industry. UVLED technology Technavio, the Asian market, predicts that the UVLED technology market in the Asia -Pacific region will grow the fastest in the future. The compound annual growth rate of UVLED technology in the Asia -Pacific region will reach 39.31%. Mainly because the region's large demand for UV curing equipment and technology. China and India are emerging markets. As the government advocates energy -saving light sources and supports the control of industrial, medical and scientific departments, these policies encourage UVLED manufacturers to increase the production of UVLED. LED optical curing applications are currently concentrated in the three major areas of wood, ink and UV glue. In the next few years, there will be a significant increase in. The European market UVLED technology European UVLED technology will increase from US $ 36.28 million in 2015 to 190.2 million US dollars in 2020. The prohibition of environmental supervision of harmful substances and the prohibition of mercury lamps has made the European market an important contributor to the global UVLED market revenue. Because UVLED is environmentally friendly and has a small power consumption, it has a lot of applications in European medical, adhesives, and printing and curing markets. These applications have also become a major factor in the growth of the European market. UVLED technology UVLED technology in the North American market accounts for 26.8% of the North American market share. Technavio predicts that the North American UVLED technology market will increase from US $ 34.33 million in 2015 to US $ 1790.6 billion in 2020. Due to the rapid growth of the market, the graphic art industry in North America is increasingly using ultraviolet curing equipment and technology. Other UVLED optical curing applications involve the medical industry, communication equipment industry, automobile industry, building materials industry, etc. UVLED resin Due to UVLED as a single -band UV light source, the cause of the absorption of the dotter to the launch of the spectrum of LED needs to be matched with LED. At present, there are not many trigger agents for LED light sources. Therefore, the matching of the cause of the cause has always been the difficulty of LED light solidification. At present. And these causes at 365nm, 385nm, 395nm, and 405nm do not have a very strong absorption peak, so the efficiency is not high efficiency. At the same time, compared with traditional mercury lamps, its power is low and the radiation energy is not high, especially in the ink color system. If the printing speed is too fast, it can easily lead to the ink solidification. The problem, the optical curing resin for LED curing must have very high reaction activity to avoid problems such as poor curing and other problems. At present, there are very few UVLED solid resins that can be selected in the market, which are mainly subject to the two major problems of reaction activity and stability. The balanced and curing speed of the curing speed, anti -surface oxygen resistance and storage stability, anti -surface oxygen blocking and storage stability are three important aspects of UV photosensitive technology. It is relatively easy to achieve it alone, but if all three are all, all three are both. It is very difficult to take into account both. Through a large number of experiments, Runa Chemical researchers have changed the resin structure with innovative methods, and auxiliary means have specially developed three UVLED solid resins with different application systems, which perfectly achieved the speed of solidification, anti -surface resistance surface The balance of oxygen blocking and storage stability, so as to solve the actual application problem well. The direction of wood and plastic coatings FSP8370 is a four -way feature -specific modified polyester acrylic. It is developed and applied to LED wood and plastic coatings. The resin is low -energy solidification speed, high conversion rate, high hardness, and excellent wear resistance and water -resistant and boiled properties. During the experiment, using 395nm dot light sources with only 200mW/cm to illuminate for 10 seconds to make dry. FSP8370 not only has outstanding reaction activity, but its storage stability is also very excellent. In the formula where there is a trigger agent, put it in a 60 C oven for 2 weeks, the viscosity is basically unchanged, and the thermal stability is excellent. UV glue direction FSP8376 is the two -official specialization of polyurethane acrylic, which is developed and applied to UVLED adhesive system. The lipids are fast -moving, low shrinking, and have excellent internal agglomeration and water resistance. The adhesive strength to plastic substrate is high. Its extension rate is 130%. Ink direction FSP8374 is the two officials' specialized modified polyester acrylic, which is specially developed and applied to the UVLED ink system. The tree lipids are solidified and flexible, with excellent pigment moisturizing, good flexibility, and have good adhesion for plastic, metal, and glass. Good printing adaptation also makes it suitable for rubber printing and silk printing technology. UVLED's application of UV inkjet in optical curing. At present, the market has high attention to UVLED curing technology. Among them, the inkjet field is the most innovative, and the advantage of UVLED solidification can meet the needs of this field. UVLED inkjet advantage: energy conservation, efficient, high resolution, adapting to multiple substrate materials. Application field: Industrial or decoration printing, large surface inkjet printing, label and packaging printing. Compared with ordinary UV printing, the UV rubber printing LEDUV printing is more energy -saving and environmentally friendly during the entire printing production process. It can reduce energy consumption by up to 70-80%. PCB industry components (capacitors, inductors, various plug -ins, screws, chips, etc.) fixed. Wide -proof irrigation and core circuits, chip protection, antioxidant coating protection. Circuit board preservation (angle) coating. Ground line, flying line, coil fixing. Polying on the welding hole mask. Compared with the traditional coating method, UVLED will not affect the moisture content of the substrate, and it will fully realize the rapid solidification of UVLED from closed bottom, primer, color repair, and facial paint. The long drying and solid time of the noodle paint and the complicated processes of the low -fixed -fixed spraying construction can achieve mechanization and assembly line operation throughout the line. UV adhesives have many advantages using UVLED curing glue, such as low heat insulation, lower energy demand, saving solidification time and location, increasing productivity, and easier to automate. Therefore, it is widely used in the field of microelectronics industry and medical equipment, play a role in bonding, fixing, and protection. UV -nail polish is cured with low -power LED lights. The use of heat in use is low, UV nail polish gel curing effect is good, which can be kept bright for a long time. UV coatings LED advantage: cold light source, less pollution, fast solidification, low energy consumption, and superior membrane performance.

Applications For UVC-LED Light Disinfection
Applications For UVC-LED Light Disinfection
UVC radiation is a well-known water,air,and transparent or translucent surface disinfection. Many years ago, UVC radiation was used successfully to stop the spread of microorganisms like tuberculosis.Due to this property, UVC lamps are frequently referred to as "germicidal" lamps. The SARS-Coronavirus, which is a distinct virus from the present SARS-CoV-2 virus, has been demonstrated to have its outer protein coating destroyed by UVC radiation. In the end, the virus is rendered inactive as a result of the annihilation.UVC- Light disinfection is a handy tool to disinfect surfaces, especially under the current circumstances. The UV-C Light Disinfection Due to its high effectiveness and low cost, ultraviolet germicidal irradiation (UVGI) is frequently used to disinfect the air, water, and other types of surfaces. It is generally known that ultraviolet radiation can make germs and viruses inactive. Since bioaerosols strongly absorb their wavelengths, shortwave ultraviolet C (UV-C) light with a wavelength of 100–280 nm is frequently employed in UVGI. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) damage caused by radiation can render bacteria or viruses inactive. Application For Uv-C Light Disinfection Due to their inherent advantages and limitless potential, UV light applications are fast replacing other methods of surface, air, and water sterilizing in many sectors. Medical disinfection Experts in the lighting business believe that upper-room germicidal UV is the most efficient technique to lessen the spread of viruses and bacteria. UV-C radiation is continuously emitted above people's heads by upper-air units to clean the air in a space. Upper-room UV systems are safe for use in populated spaces because the UV-C rays really aren't directed closely at humans. It should not be a surprise that surfaces in health centers and other settings can benefit from being disinfected using UVC disinfection. UVC light can quickly kill microorganisms on a surface, including live viruses. In this situation, UVC can be far more effective and efficient than other disinfecting and cleaning techniques in healthcare institutions. Skin Treatment Electromagnetic radiation just outside visible violet light is known as ultraviolet (UV) light. Radiation with a wavelength between 740 and 380 nm makes up all visible light to the human eye. The electromagnetic spectrum's range from 400 to 100 nm includes UV light, which is invisible to us. UV LED solutions can be divided into four categories based on their wavelength. There are five types of UV radiation: ·UV-A, between 320and 400 nm, causes skin tanning ·UV-B, between 280 and 320nm, causes skin burns and the synthesis of vitamin D ·UV-C, between 200 and 280 nm, is used to disinfect ·UV-V, somewhere around 100 and 200 nm, is vehemently absorbed by water and air and can only be transferred in a vacuum. Plant Growth Fruit and vegetable shelf life has been successfully increased by controlling postharvest infections with the fatal action of UVC disinfection. The impact of UV-C irradiation in preventing postharvest disease deterioration in harvested horticulture goods by performing an immediate germicidal effect or inducing vital defense responses has been thoroughly investigated. On carrots, lettuce, tomato, and strawberry, for example, it can create implementation and application to the plant-pathogenic fungal Botrytis cinerea. In the case of strawberries, increased phenylalanine ammonia-lyase (PAL) and polyphenol oxidase activity and expression of pathogenesis-related protein genes were associated with increased resistance. Additionally, UV-C radiation can trigger defensive mechanisms, boosting the levels of chitinase and superoxide dismutase (SOD) or PAL in various fruit, including mango, peach, and strawberry. Pet Lamp The germicidal UVC lamps have emerged as the ideal ally in this endeavor. Numerous studies have demonstrated their efficiency against various microorganisms since they can eradicate up to 99.9% of the bacteria and viruses in the atmosphere and on surfaces. Additionally, these tests have demonstrated that this UVC light kills bacteria created by pets, which is quite handy at home. And it is just here that UVC lights are beginning to carve out a position for themselves in the current pandemic. The increased use of indoor lighting has raised various concerns regarding the risk we may face from these lights. To dispel those uncertainties, we must first understand that UVC lamps can harm the eye and skin tissue. They are completely safe when used in compliance with a few basic safety precautions. - These actions are listed in this article for your reference. People should not be present throughout the sterilization process due to the care that must be followed when using this bulb. Additionally, contact with UVC disinfectionradiation may cause undesirable tissue damage even though there isn't any conclusive research on the harm caused by these rays. Therefore, excluding dogs and plants from space is wise. Cannabis Is Cultivated It is suitable for permanently inactivating germs like Botrytis cinerea because ultraviolet germicidal radiation, or light energy at the UVC disinfectionwavelength (200-280nm), dissociates molecular bonds, which cleans and disintegrates organic materials. Scientists have yet to discover a microbe completely resistant to the harmful effects of UVC disinfection, including resistant bacteria and other microorganisms resistant to antibiotics. UV-C air-stream disinfecting systems and UVC disinfectionsurface disinfecting systems are the two methods for employing UV-C to inhibit the growth of mold and germs in indoor cannabis gardens.

[Driver] UVLED Driver Method Introduction
[Driver] UVLED Driver Method Introduction
When designing UVLED drivers, the appropriate driver method should be selected according to the requirements of power size, application occasion, driving performance, and economy. If the driving source performance does not match UVLED expected. This article summarizes several commonly used driving methods. UVLED constant voltage driver UVLED constant voltage source is defined as the output voltage is constant when the allowable load is constant, and it will not change with the change of the load (output current). In fact, the voltage output of constant voltage sources still has a certain ripple. It can be seen from the UVLED Voldemort characteristics that UVLED work in a non -linear area. The tiny voltage changes will cause a large current of UVLED. , High accuracy to the drive source. Figure 1 shows the local I-V curve chart of a UVLED. Figure 1 UVLED driver UVLED constant current source is characterized by the constant output current, which does not change due to changes in the load (output voltage). The constant current driver is generally divided into linear constant current and switching constant current. The switching constant current is widely used in high -power UVLED surface sources and wire light sources due to high efficiency and good stability. Figure 2 shows the basic frame diagram of a constant current driving solution. Figure 2 When designing the UVLED driver scheme, regardless of the use of constant voltage or constant current driver, in order to improve the reliability of the system, various protection measures are needed, such as overload protection, over temperature protection, etc. Author: Tianhui-Air Disinfection Author: Tianhui-UV Led manufacturers Author: Tianhui-UV water disinfection Author: Tianhui-UV LED Solution Author: Tianhui-UV Led diode Author: Tianhui-UV Led diodes manufacturers Author: Tianhui-UV Led module Author: Tianhui-UV LED Printing System Author: Tianhui-UV LED mosquito trap

CICS Related Issues of UV Glue Curing Oxygen Obstruction
Now when we do glue testing for customers, we will encounter the use of UVLED devices to irradiate and solidively, and it will be a bit sticky to touch the surface of the glue with our hands. In the inside of cutting and curing glue, we can see that the glue is completely solidified after the glue is shot with the UVLED light. Why do you have such an imagination? This has extended an important problem in the UVLED curing industry. UV glue is the problem of oxygen resistance when curing up with UVLED device. Oxygen closure is a common problem in the reaction of optical curing. In the UVLED optical reaction, the free radicals generated by the cracked light cause of the light cause will be captured by oxygen to form peroxic free radicals. The problem. The method of overcoming oxygen blocking can be divided into two types: chemical and physical methods. The method of inert gas used in physical methods to isolate oxygen is a very effective method. The commonly used inert gases are usually nitrogen, or sorbe. The cost of nitrogen and gaseous gas is relatively high, and the other inert gas that can be used is carbon dioxide. The use of carbon dioxide has some advantages that other gases do not have: First, carbon dioxide is easy to obtain, and the cost is low. Secondly, because carbon dioxide is heavier than air, it is easy to maintain in the container, so that there will be less loss.

[UV Ink] Some Problems Existing in UVLED Inks
[UV Ink] Some Problems Existing in UVLED Inks
As we all know, the UV ink printing has great advantages compared to traditional ink printing, but at the same time, there are indeed some problems that need to be solved and improved. The following talks about our views and ideas in this regard. The first is the price of UV printing ink. UV inks have the advantages of instant solidification and good conjunctival performance, but the price is more expensive than ordinary ink, and it must also use special UV rubber cloth and UV ink rollers. Cost increase. However, with the popularity and technological development of UV inks, it is believed that its price will also gradually decrease; secondly, UV inks will be solidified. Due to the internal components and aggregation, the instantaneous changes in volume will produce a large internal stress, resulting in the ink pairs of the printed seal of the ink. The adhesion of materials decreases. Through the surface treatment and modification of the printed matter, this problem can be improved. In addition, the finding and development of UV inks with good adsorption and small contraction can also improve this problem. Materials, and the preparation of inks of different printing materials and inks is not the same, so it is required to have a wide adaptability to ensure that the quality of printing is required. We believe that with the maturity of related technologies and the continuous expansion of application fields, UV inks will definitely develop rapidly; UV printing will also be widely used.
