UV ink: LED UV curing new blue sea

[Text / high-tech LED Xu Chaopeng] Recently, under the circumstance of the lack of kinetic energy of the traditional white LED business, many LED upstream manufacturers have begun to look to IRLED and UV and other invisible light markets.

Among them, Jingyuan Optoelectronics Co., Ltd., which has a complete and rich product line, has recently become more and more attractive in the new business of IRLED and UV, as the backlight market is becoming increasingly saturated and the lighting profits are gradually declining.

"Actually, due to the fierce price competition in the LED industry, many manufacturers are actively looking for new special applications that can enhance profitability. For example, the invisible LEDs that are gradually receiving attention are becoming a new direction for the industry to break through." According to informed sources.

Indeed, due to the high barriers to entry in such markets, the gross profit margin of products is significantly better than that of white LEDs, so many manufacturers have begun to lay out.

"For example, in this, UV inkjet technology is gradually becoming a bright spot." Yang Fan, general manager of Shenzhen Tongfang Optoelectronics, said that he is very optimistic about the application potential of UVLED light curing technology in the exposure market.

It is understood that the current UV LED light curing includes UV adhesive curing in the display, electronic medical, instrumentation and other industries, UV coating curing in building materials, furniture, home appliances, automotive and other industries, as well as UV in printing, packaging and other industries. The ink is cured.

"Where, UV ink refers to an ink that uses ultraviolet light of different wavelengths and energies to polymerize monomers in an ink binder into a polymer under ultraviolet irradiation to form a film and dry the ink. And it does not use a solvent, and the drying speed is fast. , good gloss, water resistance, solvent resistance, wear resistance, and pollutant emissions are almost zero." Yang Fan mentioned.

According to the reporter, after using the UV LED light source, it will have many advantages: First, the long life, the service life of the LED lamp is more than 10 times that of the traditional mercury lamp, about 25,000 to 30,000 hours; secondly, the stability is high. The stability of the LED lamp makes the output energy predictable and stable, so the printing effect is also greatly improved; finally, the maintenance cost is almost zero, and the UV-LED curing equipment saves at least 10,000 yuan per unit of consumables per year. .

“Overall, the future UV-LED replacement mercury lamp may become the mainstream. After all, its advantages are obvious and visible. At the same time, due to the great advantages of LED curing light source, coupled with the current LED curing device. Going to the market, the research and development of LED curable inks in the future will become the focus of the development of the UV ink industry." Yang Fan finally mentioned.
