Development Trend of UV LED Light Source

In the past, ultraviolet light source was widely used in printing industry, such as high-pressure mercury lamp and metal halide lamp. Because of large-scale lamps and power equipment, users are worried about ozone and other problems in the process of printing machine and matrix damage caused by high power consumption and heat. With the emergence of UV curing technology, more and more attention has been paid to its environmental characteristics, less environmental pollution, lower operating costs and solvent types compared with solvent types. The results show that the market share of UVled flat-panel printers is 11.7%, while that of solvent-based wide-ink-jet printers has dropped to 33.6%. Ultraviolet curing technology is a green industry. As a new technology, UVLED has become the "5E" feature of industrial technology of the North American Radiation Therapy Commission. It fully demonstrates the characteristics of technology, namely, high efficiency, energy saving, environmental protection and wide adaptability. Ultraviolet mercury curing lamp is commonly used in the market, which is called mercury arc lamp. Ultraviolet mercury lamp has limited life and great energy consumption, but the effective use of energy is not high. In addition, although Ultraviolet mercury lamp has no VOC emission and environmental protection characteristics compared with solvent-based ink, Ultraviolet mercury lamp has some hidden pollution, such as easy to produce ozone, which has greater impact on health. The first appearance of LED curing technology has attracted widespread attention in the industry, and many printer and ink manufacturers have demonstrated their own technology. LED curing is the most attractive technology in the field of energy curing. This technology is becoming more and more popular in energy saving, high efficiency, economy, environmental protection, wide adaptability of ultraviolet and non-infrared radiation sources.
