In the past, ultraviolet light sources used in the printing industry generally used light sources such as high -voltage mercury lamps and metal halogen lamps. Due to the large volume of lamps and power devices, users were worried that the power consumption and the large heat were caused. And during use, ozone and other problems. With the advent of UVLED optical curing technology, because of its environmental protection characteristics, environmental pollution is less than the solvent type, and the operating cost and solvent type will even be lower. Therefore. The survey results show that the market share of the LED-UV tablet printer has rapidly reached 11.7%, and the market share of the wide-sources of solvent type has fallen to 33.6%. UVLED optical curing technology is a new technology of green industry. It has been rated as an industrial technology with the characteristics of "5E" by the North American Radiation CICC, which fully demonstrates the characteristics of this technology, that is, efficient, energy saving, environmental protection, economy, adaptability, adaptability wide. At present, the UV curing lights commonly used in the market are generally mercury arc lamps, referred to as mercury lamps. The UV mercury lamp has a limited service life, and the energy consumption is large but effective. In terms of solvent -type ink, because there is no VOC emissions, it has the characteristics of environmental protection and environmental friendliness, but there are some hidden pollution in UV mercury lamps, such as easy to produce ozone, and it is easy to leak mercury. These are all on the body for the body Health has a great impact. UVLED curing technology appeared at the Druba exhibition for the first time, which attracted widespread attention in the industry. Many printing machines and ink manufacturers showed their own technology. LED solidification is the most attractive technology in the field of energy curing. This technology has become increasingly the characteristics of energy saving, efficient, economical, environmental protection, and adaptability, as well as cold light sources without infrared radiation, and ozone -free release. The more people are favored by people. At present, the market's demand for LED UV technology is very strong. Digital printing has become the largest market for this technology. Among them, the inkjet field is the most innovative, and the advantages of LED UV can meet the needs of this field. Tianhui has always regarded energy conservation and environmental protection and efficiency as the mission and pursuit of the enterprise, especially in UVLED curing technology and products, and strives for excellence to continuously provide cost -effective UVLED solutions for various industries. make a contribution!

UV LED diodes have become prevalent in an assortment of applications, including disinfection, industrial curing, and specialization light. Their value arises from their capacity to deliver accurate and efficient UV light tailored to individual requirements. Classical mercury lamps, which have been performing comparable roles, are steadily being replaced with UV LED diodes since of their greater performance and eco-friendliness. This article explains why UV LED diodes are an excellent choice for current applications.
The sole UV light source that could start the UV curing process forty years ago was mercury-based arc lamps. Even though Excimer lamps and microwave sources have been invented, the technology has not changed. Like a diode, an ultraviolet light-emitting diode (LED) creates a p-n junction using p- and n-type impurities. Charge carriers are blocked by a junction boundary depletion zone.
