Uv LED curing light source in A new era of "full", special UV LED curing is expected from the outbreak in 2018 ~ 2017 growth, uv-a and UV - C band has the greatest potential to market, from 3 d printers LED light source component technology, more short wavelength is more difficult, compared to the competition of grain trade is numerous, blue LED UV LED crystal production difficulties, the technical threshold difficult more than 10 times, especially short wave period of relatively few of the manufacturers, not through throw money or poaching can be solved.

UV LED curing light source is A technology that has only been expanded for 2~3 years. The UV-A band of special UV LED curing is about 320~400 nm, uv-b is about 290~320nm and uv-c band is at 240~ 290nm. At present the industry development of 3 d printers LED light source is mainly concentrated in the visible part, including backlit, lighting, etc., however, affected by the price war, emphasize standardized specifications of lighting product prices continue to decline sharply, lead to the LED industry faces a severe shock.

According to the market, estimates that global Uv LED curing light source sterilization market value of $500 billion, due to the special UV LED curing UV -c principle is the use of absorption band bacterial DNA chain will interrupt, to bacteria can no longer reproductive sterilization function. This was originally applied in industrial wastewater treatment, although 3 d printers LED light source UV - CLED conversion efficiency is still very low, only about 1 ~ 2%, compared with 10 ~ 20% of the tubes, but cannot do UV lamp handheld products. As visible light leds have become red sea market, ultraviolet light (UV LED), infrared (IR LED) is not visible in the application fields are also carried out, because of the technical barriers to entry, many applications in industrial or customized products, price competition will hopefully from low unit price.

In addition, the traditional high temperature of UV lamp and the production of ozone problem, so the factory must also install the air conditioning system by pulling out the ozone, so when the UV exposure - ALED application to curing or manufacturing, not only save the lamp power costs, and the overall environment, air conditioning and other fee. However, UV LED curing light source belongs to single wavelength and directivity characteristics, while traditional UV lamp tube is multi-wavelength, which also increases the threshold of special UV LED curing uv-a LED to the market. When 3 d printers LED light source UV - ALED to replace the tubes, because the original printing ink is in accordance with the wavelength allocation to design more, so the single wavelength must mix light, and light intensity, irradiation distance, uniformity and so on all need to do overall consideration, irradiation accuracy is high, light Angle is small, only about 1 ~ 6 degrees of parallel light.
