UVLED development history and current situationread count [464] release time：2019-12-21 20:51:00
UV LED curing is a type of ultraviolet (UV) curing in radiation curing. As a company focused on uvled curing As a technology development and research company, we have also witnessed with our own eyes the rapid development of UVLED curing technology in recent years. Today, let’s learn about UV together led technology of Development history and present of development status. 1960s UV light curing Technology began to appear in the West. In the development process of the following decades, coating and light source technology continued to improve and diversify, thus forming a relatively independent and mature industrial system. However in In the past ten years, the optical power output per square millimeter of the chip has roughly increased four times. Especially for UV LED chips with 385nm/395nm as the main wave peak, the optical power output is close to 800~1000mW, which can already meet the radiation intensity requirements of high-intensity curing. . Before 2000, UV light curing used mercury arc lamps or electrodeless mercury lamps as ultraviolet light sources. After 2000, solid-state light-emitting technology with emission wavelengths below 400nm has continued to advance, and it has gradually become possible for UV LEDs to be used in curing. The earliest research and development of UV LED curing technology in the West began in 2003-2005. For example, the American Phoseon Company and the British UV Integration Company did a lot of early application exploration research. The research and development of UV LED in China began in 2008-2010. Yongcheng Optoelectronics began to expand its UVLED business in 2009, and was one of the earliest domestic manufacturers to enter the field of UVLED curing light sources.
In the early days, due to the constraints of the low output power of UV LED chips, UV LED curing technology was stuck in the conceptual promotion stage for a long time, with few practical application cases. This situation did not improve until 2013. Since then, UV LED light curing has been widely used in many fields such as inkjet printing, letterpress printing, offset printing, flexo printing, screen printing, etc., especially in China's narrow-format printing industry. The installed rate of UV LED curing systems for new machines has even exceeded 50% in 2018, and the UV system LED modification rate of a large number of sold equipment is also more than 10%. The UV LED-related coating and ink industries, as well as the curing light source industry, will still be in a period of stable and rapid growth in the past few years and in the next few years.
Shenzhen Yongcheng Optoelectronics Co., Ltd. was founded in 2009 , has been listed on the New OTC Market in July 2018 and is UVLED The first listed company in the curing industry. Headquartered in Shenzhen, with offices in Shanghai, it is a company engaged in UV It is a national high-tech enterprise integrating the development, manufacturing, sales and service of LED curing equipment and has more than ten patented inventions. Professional production and sales UV LED point light source , line light source, surface light source, curing machine and other products. At present, the company's sales and service network covers many countries and regions in Asia, Europe, America, etc. After years of unremitting efforts, Yongcheng Group has become a leading enterprise in the UV LED curing industry. Its products are widely used in printing, furniture coatings, inkjet printing, industrial printers, rotary machines, light curing, exposure machines, screen printing machines, optical fiber communications, electronics, textiles, medical and other fields.
