UV LED progresses in the future and will "kill" bacteria
The mainstream of external LED development is UV-A LED and UV-C LED, among which UVA LED is more focused on the light curing market, and UVC can be used in food preservation, air purification, water purification and other markets. In the context of oversupply and low gross profit in the LED industry, major companies are actively capturing the fast-growing, high-profit-driven UV LED market, and universities have begun to conduct related research. Let's take a look at the three latest developments. (a) 265 nm - 275 nm wavelength UVC LED package product launch greatly shortens sterilization time The UVC deep ultraviolet disinfection market is widely used. In 2016, the market value of UVC LED sterilization and purification applications reached US$28 million, and will reach US$257 million in 2021. The annual compound growth rate is as high as 56%. Taiwan's LED factory Guangsheng and Yanjing are optimistic about the potential applications and business opportunities of UVC LEDs. The joint venture creates the brand “Bioraytron†to integrate the upstream and downstream technology advantages of the industry, and launches UVC LED package products from 265 nm to 275 nm, and plans to introduce people's livelihood consumption. , medical sterilization and testing equipment, industrial and high-tech water sterilization treatment and other industrial fields. Bioraytron products are divided into optical and crystallographic technologies. The company is responsible for the production of UVC LED epitaxial wafers and chips. It is exclusively supplied to Ricoh to package UVC LED components and module products, and then sold to the deep UV UVC industry through the Bioraytron brand. client. The UVC band is from 200 nm to 280 nm. The main function is disinfection and detection materials. It can be widely used in air/water/surface purification, medical testing instruments, food preservation and other markets. The potential demand is amazing. However, the UV-C LED product technology threshold is quite high, and it faces many challenges in terms of epitaxial, chip technology, packaging and market acceptance. Dr. Wei Zhihong, Chairman and General Manager of Yanjing Optoelectronics pointed out that there are two main points of disinfection and sterilization. One is to select the correct wavelength, and the absorption spectrum of bacteria and microorganisms should be about 264 nm. The second is to have enough dose (Dose) to effectively sterilize. The role of disinfection. “Dose (mJ/cm2) = UVC radiation intensity (mW/cm2) x time (Sec)â€, the higher the UVC radiation intensity, the shorter the sterilization time, so to achieve the “second kill†degree, UVC LED The light intensity must be increased. Xu Mingsen, general manager of Optoelectronics Technology, said that time is the key to entering the consumer application market. Once the wavelength is selected, the sterilization time can be shortened, and the UV LED performance is improved, including increasing light intensity, reducing the angle, etc. will be better. Bioraytron's UVC LED products are capable of achieving the world's highest radiation intensity of 25mW/cm2 at a radiation distance of 10 mm and an input power of 1.2 W, and are the leading UVC LED US-Japan plant. Effectively shortens sterilization time and increases product design freedom. At present, Bioraytron's UVC LED package products have reached a light output of 1 to 4 US dollars per milliwatt (mW), and will continue to work at a higher cost. Bioraytron will give priority to the Minsheng consumer industry in 2017, and the annual production capacity of UVC LED will reach 5 million. Next, it will be introduced into the medical sterilization and testing equipment, industrial water sterilization and other industries. 50 million, in addition to the simultaneous development of UVB LED applications. (2) Medium power UV LED is introduced for sterilization and health treatment RayVio, Inc., a leader in deep-UV LED devices and disinfection systems solutions, today announced the availability of its XE series of medium-powered ultraviolet (UV) LEDs with a rated output of 6 milliwatts (mW) in an ultra-small 3535 package. With 280 and 310 nm spectral output, RayVio's XE series will inactivate the DNA of bacteria, viruses and other pathogens and thereby prevent disease. ayVio's XE series is the smallest commercial UV LED, a feature that gives the product unparalleled flexibility to integrate with a range of products, including automatic disinfection bottles and hospital surface cleaners. Since the XE series' optical power output is more than twice that of the same size UV ​​LED, it saves battery life and can be used in almost any solution.
