At present, UVA is mainly used in the UV curing process (wavelength is between 315nm-400nm). At present, most of the applications of UVA can be achieved by UV LED. UV LED curing technology has obvious environmental advantages. First of all, UV LED lamps are very energy-efficient. The UV LED lamp is equipped with a switch that cuts off the power supply in standby mode, thereby reducing power consumption. Now, many offset presses use UV LED curing technology to reduce power consumption. At the same time, the UV LED lamp does not produce infrared rays, which can release energy to cure the ink while keeping the temperature of the printed product constant. Unlike mercury lamps, which need to be equipped with a cooling roller to reduce the impact of heat release on the printing material, it is especially suitable for heat-sensitive materials such as films. Printing. UV LED lamps have a longer life span than mercury lamps, and the light performance will not decrease over time.
Global UV LED curing market analysis:
In terms of the entire UV curing market, in 2008, UV LED curing only accounted for 9% of the entire UV curing market. Since 2009, the proportion of UV LEDs in the curing market has continued to increase. By 2017, UV LED curing accounted for 43% of the entire UV curing market.
Before 2019, UV LED curing is still the main market for UV LED applications. In 2008, UV LED curing accounted for 48% of the UV LED application market share, and then increased year by year, reaching 80% in 2016, and then its relative market share began to decline. According to Yole's forecast, in 2020, the market share of UV LED in curing applications will drop to 41%, which is lower than the market share of UV LED in water and air disinfection and purification (45%). The main reason for the decline in UV LED curing market share is the rapid growth of the UVC disinfection and purification market for water and air surfaces.
As far as the chip and packaging market is concerned, around 2011, the global UV LED curing market expanded rapidly, which directly promoted the growth of the entire UV LED chip packaging market. In 2011, the year-on-year growth rate of the UV LED curing field was as high as 45%, while the year-on-year growth rate of the entire UV LED market was only 28%. In the following 2012-2014, the UV LED curing market maintained an annual growth rate of 50% for three consecutive years. Although its growth rate has slowed since 2015, UV LED curing still accounts for the largest proportion of the UV LED application market.
