Currently widely used in lighting, display and other fields of visible light GaN based blue, green and white LED market competition, has become the deep red sea". Therefore, the market has gradually been considered to be the "blue ocean" ultraviolet (UV) band penetration. However, due to the high demand for production of UV LED technology, the market is small, so manufacturers are not many
UV LED basic market conditions
From the technical level and the market, the UV LED market can be divided into deep UV and near UV two blocks to be assessed, because the two technologies, applications, price differences are very large. UV LED product specifications EBOHR can be divided into UV-A (long wavelength ultraviolet, 320~400nm), UV-B (medium wavelength ultraviolet, 280~320nm) and UV-C (short wavelength ultraviolet 200~280nm) three categories.
From the current technology and market, the industry generally believe that the UV-B and UV-C of the world is doing the best American SETi, dominated the deep UV LED performance throne has been more than 10 years. Qingdao is China Jason Chinese deep UV LED do best company. LGIT recently rumored to use the new design of the MOCVD machine and new technology to produce deep UV LED, good performance, but the market has not seen the product. UV-A band do best is undoubtedly nichia.
The second tier is South Korea's LGIT and Seoul semiconductor. Seoul semiconductor into the UV market has been a long time, with some of the shares of SETi.
The third tier is the United States Lumileds and Europe's Osram, it is estimated that the two companies are not enough emphasis on UV business, so the performance is not as good as the South Korea's top two companies.
Followed by Taiwan company, including macro, light, and so on, and the mainland Liansheng Xuming company.
Jingrui photoelectric ceramic package with the bright younger generation, application latticepower developed 395-405nm efficient near UV 45X45mil flip structure and vertical structure of the LED chip, the performance reached the international level, the product has been applied in industrial fields, Manicure curing equipment, has been widely praised at home and abroad customers.
Ultraviolet UV light was successfully extended to all walks of life
As we all know, more than thirty years ago, ultraviolet (UV) was successfully applied to commercial applications. Adhesive manufacturers for the UV light curing characteristics, developed for bonding, sealing, printing and other series of UV products, and widely used in communications, electronics, optics, printing and many other fields. These products in UV light (wavelength and light intensity) irradiation, will be cured or hardened (polymerization), and with the traditional products UV light curing efficient, energy saving and environmental protection more quickly.
UV curing equipment has also undergone continuous development and improvement of the process. The production process of mercury lamp irradiation was adopted for a long time. But the equipment is expensive, high maintenance cost, UV light intensity attenuation, increased surface temperature, irradiation element of large volume, expensive consumables, Gong pollution and other defects, the industry has been working to improve, but because of the limitations of the original hardware has been difficult to break.
The advent of UV LED, UV curing industry has brought revolutionary changes. It has a constant light intensity, excellent temperature control, portable environmental characteristics, the purchase cost is more relatively low and almost zero maintenance cost, to enhance the quality of the UV curing process and energy saving plays a role.
UV point light source, UV line light source, UV surface light source has begun to be used in various industries. We believe that through the joint efforts of the industry, the future of the UV curing industry will have a new world of environmental protection and energy saving.
Service life
The traditional UV curing equipment with respect to the lamp service life is only 8003000 hours by UV LED UV curing system for the service life of 20000-30000 hours. The LED can only in the moment when the need for UV light, according to the DUIY=1/5 (time to prepare the exposure time of =5 =1), 30 to 40 times the way the use of LED is equivalent to the lamp life. Reduce the time to replace the bulb: improve production efficiency, but also very energy-efficient. While the traditional mercury lamp curing equipment in the work, as a result of mercury lamp start slow, open and close the lamp life, must be lit, not only caused unnecessary power consumption and shorten the service life of mercury lamp. UV LED curing machine
Non thermal radiation
High power LEDs without infrared emission. The surface temperature of the irradiated product is 5 degrees below C, while the traditional UV curing system of the mercury lamp will generally increase the surface of the irradiated product by a factor of 60 to 90 DEG C. UV-LED curing method is the most suitable for plastic substrate, lens bonding and electronic products, fiber optic cable and other heat sensitive, high precision bonding process requirements.
Environmental pollution
The traditional mercury lamp curing machine adopts the method of mercury lamp luminescence, and the bulb has mercury, and the waste treatment and transportation is very troublesome. The LED curing machine using semiconductor light, no environmental pollution factors. Therefore, the use of LED curing machine more environmentally friendly.
Super illumination
High power LED chip and special optical design are used to achieve high precision and high intensity irradiation of UV light, and UV light output reaches 8600mW/m2. The optical technology and the latest manufacturing technology, to achieve a high strength output more optimized than the traditional way and the uniformity of the mercury lamp, mercury lamp is almost 2 times the traditional way radiation luminosity, make UV faster curing adhesives, shorten the production time and greatly improve the production efficiency.
The increase of the channel will lead to the decrease of the output energy of a single irradiation channel when the light source is solidified by the traditional mercury lamp. While the irradiation of the LED type, each of the radiation head independent light, the irradiation energy is not affected by the increase of the channel, always maintained at the maximum.
Compared with the mercury lamp, the UV LED shortens the irradiation time and improves the production efficiency.
Low energy consumption
The UV LED method is more than 10 times higher than the mercury lamp.
At the same time, regardless of whether or not the effective way to mercury lamp, mercury lamps need to work continuously, the power has been in a state of consumption. While the UV LED mode only consumes power when it is irradiated, and the power consumption is almost zero in standby. Can do a simple calculation, each point light source curing machine to save electricity:
270 (Watt) *8 (H) *365 (days) = 800 (KWH)
Thus, each year only power consumption can save thousands of dollars. Not only that, by saving electricity, each unit can reduce carbon dioxide emissions by 1.4 tons per year, equivalent to a year of the car exhaust.
Easy installation, saving space
The size of the LED curing machine is only 1/5 of the traditional curing machine, which makes the installation of the equipment more simple and reduces the occupied area of the site

UV LED curing technology will make great progress
LED curing is one of the most attractive technologies in the field of energy curing. In 2008, LED curing technology debut at drupa, and caused widespread concern in the industry, many printing machine and ink manufacturers show this technology, their own at the same time, it has made some progress in the field of jet, Sun Chemical and INX? Digital is a leader in the field.
Drupa 2008 is UVLED technology for the first time caused by a show of concern, is also in this exhibition, inkjet technology has been hitherto unknown attention and achieved great success.
At present, the market demand for UVLED technology is very strong, digital printing has become the largest market for this technology, of which the most innovative inkjet field, while the advantages of UVLED just to meet the needs of this field. Of course, LED technology in order to become the mainstream inkjet technology, it will take some time.
Although LED technology has been around for some time, the development of LED ink is the main driving force for the development of this technology.
The main contribution of this technology is the ink formulation. Early LED ink needs to be adjusted or re made to meet the requirements of LED curing, and now customers can be designed specifically for the UVLED curing equipment and ink.
UVLED technology has many unknown advantages. First of all, it has a very long life, generally can reach 20 thousand to 30 thousand hours. At the same time, the power consumption is very low, especially in the flexo and sheet fed printing, printing almost 50% of electricity; secondly, UVLED curing unit does not produce ozone, covers an area of small, integrated and easy to control, simple maintenance.
UV curing ink
In addition, LED lamp is also a very important technology, it can not only reduce the complexity of the installation of UV curing lamp, but also reduce the curing process on the environment, human health and safety.
According to Sun Chemical Company, they can provide different UV ink for each industry LED curing unit, but most of the current LED lamps are used in the field of inkjet.
Department of Sun Chemical SunJet inkjet ink is UV curing ink development leader in the field, but also for the development of LEDUV lighting technology made distinctions won in battle. With the development of curing lamp technology and the emergence of high-power spotlights, SunJet pioneered the development of a completely exposed LEDUV printing ink.
At the Print09 show, INX Digital, a short version of the narrow UV LED printing machine, it can be set up to 80 feet per minute. Recently, the company has launched a UV curable pigment ink LED-INX to meet market demand.
In the traditional printing ink, some ink manufacturers have seen the growth potential of UVLED, and its full preparation.
Almost all of the printing process can use UVLED technology, flexo printing is a good example, sheetfed offset market prospects are good, but for the high speed, large sheet printing machine, it is difficult to use this technology, and economic factors to the promotion of UVLED technology also has certain effect.
In any case, LED is the most popular technology in the past two years, everyone wants to know how it works, but also to bring benefits to customers. But the real choice of such equipment enterprises are relatively small, and the economic downturn, lack of liquidity of the enterprise has a great relationship.
In addition to LED curing technology is highly respected in the field of inkjet, the technology is also beginning to UV flexo and UV lithography field penetration. At present, the price of LED is still very expensive, the production of special ink raw materials are relatively rare, so this technology in the next few years there is still much room for development, the price is expected to further reduce.
LED output continued high growth in advance to achieve 20% market share
LED lighting industry to maintain rapid growth in recent years, the prediction of Ding Wenwu on the Ministry of electronic information division, the rapid growth of domestic LED output will continue to maintain 20% to 30% next year, growth share occurred mainly in the civil and road lighting and other public areas. In addition, Lv Wenbin, deputy director of the NDRC resource conservation and environmental protection department is expected in 2015, LED lighting market share of 20% of the target will be achieved ahead of schedule.
Sponsored by the United Nations Environment Programme and the global center for efficient lighting technology co sponsored by the Global Forum on efficient lighting, yesterday (10) held in Beijing. The United Nations Environment Programme through the research on the global lighting market in more than and 150 countries, pointed out that the current lighting electricity accounted for more than 15% of global electricity consumption, carbon dioxide emissions accounted for 5% of the world; and the application of advanced lighting technology represented by LED, carbon dioxide emissions can be reduced more than half of the global lighting electricity generation, emissions equivalent to the entire australia.
In 2011, China issued the "China phasing out incandescent roadmap", and in October this year, through the prohibition of export and sale of incandescent lamps above 60W requirements. Promotion of energy-efficient lighting products, not only conducive to sustainable use of energy and environmental protection, but also help to form a new economic growth point. China as the world's largest lighting products production, consumption and export country, the rapid growth of the domestic LED industry, in 2013 the market size of more than 260 billion yuan.
Ding Wenwu said that China's LED industry output growth rate of around 30%, the main device light-emitting efficiency has been close to the international mainstream level, basically complete industrial chain. But at the same time, there are still some problems, in addition to the overall technical and international advanced level gap, the quality and safety of lamps is the main problem. He believes that if further cooperation with international companies and research and development institutions, to solve the quality problems, in the next 3 to 5 years, the market price of LED lighting products will fall within the acceptable range of Chinese people.
For the EU to improve the standard of LED lighting products, Ding Wenwu told reporters that the improvement of the standard in the long run is a global behavior, domestic standards are also improving, which plays a regulatory role in the transformation of China's LED enterprises.
Yesterday (10), the global Lighting Forum on the 27th, the global lighting association president Jan Denneman said that as the analog signals into digital signals, from incandescent lights change to LED lighting heralded a revolution in lighting energy efficiency. He predicted that by 2030, the global LED lighting will be achieved.
