The UVC LED inquiries of Taiwanese factories have increased significantly

With the spread of pneumonia, the demand for sterilizable deep ultraviolet (UVC) LEDs has also attracted more and more attention. Everlight (2393-TW), etc., has actively developed UVC LED products and successively mass-produced and shipped. Although customer inquiries have greatly increased, Taiwanese factory UVC products have relatively small production capacity compared to other products, and this year ’s revenue contribution may still not be. obvious.

The UVC wavelength is between 200-280 nanometers. It is the only one of the ultraviolet rays of each wavelength that has a sterilization and disinfection effect. The ultraviolet radiation of bacteria, viruses and other microorganisms can destroy DNA (deoxyribonucleic acid) or RNA in the cells of microorganisms. (Ribonucleic acid) structure, attack DNA and annihilate harmful organisms, causing cell death or loss of reproductive capacity, to achieve sterilization and disinfection effect.

In the face of competition in the LED industry in the Red Sea market, Chinese manufacturers have seized the market to grab market share. LED manufacturers have suffered terribly in the past few years, and operations have been hit hard. Many manufacturers have withdrawn from the lighting market and turned to niche market layout with better gross profit. LED is one of them.

Jingdian has previously launched 275-285 nanometer UVC LED products. Chairman Li Bingjie is optimistic about the future market potential of UVC LED. It will have great room for application in smart home appliances and home lighting, but there are still higher costs. Problems need to be overcome, product benefits still need time to ferment. Jingdian said that it is still in the stage of small shipments, and more and more customers are evaluated.

Lunda recently launched a variety of new UVC LED products, including PU35CL1 with low energy consumption, small package, and suitable for portable sterilization products. Currently, it has begun to ship, but the volume is still not large; PU35CM1 in white goods.

In addition to Jingdian and Lunda, Lite-On also launched 270-280 nanometer UVC LED chip products, which can output up to 130mW of ultraviolet light, from consumer electronics equipment sterilization, air / surface sterilization, drinking water sterilization, still water sterilization and other applications , Continue to advance to the field of industrial water treatment.

Everlight has also introduced UVC LEDs into eggshell sterilized UVC LED modules, water purifiers and mosquito traps and other applications. Recently, it has received orders for UVC LEDs. To this end, it has increased the monthly production capacity of UVC LEDs to 5 million pieces and delivered them. Module factory, producing a series of disinfection and sterilization products.

Baihong (3031-TW) has also developed the UVC LED packaging technology last year. It is currently in the stage of sample delivery. The customer has a high degree of inquiry and there are many samples, but they are all in small demand. Mass production in the second quarter.

As various manufacturers accelerate the development of UVC LED products, more and more applications are coming out one after another. Although UVC LEDs are still facing higher cost issues, experts pointed out that the United Nations concluded the Minamata Convention in 2013, requiring the State party to start from this year The prohibition of the production, import and export of fluorescent lamps with a mercury content of more than 5 milligrams, coupled with the increasing quality of life and health, is expected to accelerate the development of UVC LED sterilization and purification applications.
