In the Spring Festival of 2020, affected by the new type of coronal epidemic, ultraviolet lamp, as one of the disinfection and sterilization schemes, never expected to embark on the stage of public focus in such a worrying way.

At this time of crisis, high hopes were placed on them. The manufacturers of UV products and UV industry also fulfilled their mission. Philips, OSRAM, xuelaite, guangmingyuan, Leishi and Foshan Lighting immediately responded by donating ultraviolet germicidal mercury lamps in stock to support Wuhan.

In addition, the 10000 sets of UVC led disinfection bags donated in the first time in 59 seconds also attracted great attention, and solved the disinfection and sterilization problems of medical staff's mobile phones, masks, stethoscopes, thermometers and other items.

UVC LED as a future alternative to UV mercury lamp, after the outbreak of the epidemic, the problem of cost reduction and efficiency improvement is more urgent.

And San'an photoelectric and Guoxing optoelectronics are used as UV Novel coronavirus, LED technology representative, also issued the initiative at the very first time: willing to work with industry and society to provide known effective bactericidal wave products, accelerate the sterilization test and research of UVC on special viruses such as new coronavirus, and develop and study comprehensive prevention and control measures for effective diseases as soon as possible, contributing to the cause of human disease prevention and control.

So, under the influence of the epidemic, will it really help to speed up the R & D of the industry? Will UVC LED industry break out ahead of time this year?

Regardless of the background of the epidemic, according to the data from the industry research center of experts, the global UV LED market size will reach 269 million US dollars (about 1.9 billion yuan) in 2019, which is expected to become the first year of UV LED real high-speed growth. By 2024, the global UV LED market size is expected to exceed 1 billion US dollars, and the compound growth rate will reach 31% in 2019-2024. As an important part of UV LED industry, UVC led accounts for more than 20% of its output value, which is mainly used in sterilization, disinfection and other fields.

With the rapid development of the entire UV LED industry, and driven by the epidemic, UVC LED may be expected to enter the fast lane of growth this year. Why do you say that? Let's take a look at the two major problems hindering the development of UVC led.

In the general consumer market:

1) The mass market has no rigid demand for disinfection and sterilization. Bacteria have been living on the earth for billions of years, and bacteria and humans are in symbiosis in many cases. In the environment that does not affect human life and work, the demand for disinfection and sterilization in the mass market is not strong. In addition, due to the fact that UVC is invisible, invisible and intangible, colorless and tasteless, consumers are unable to perceive the working effect of UVC led, and the market has a shallow understanding of UVC led, which makes it difficult for enterprises to open the market and promote it.

2) Even if the mass market is aware of disinfection and sterilization, there are many ways to choose, such as ozone sterilization, high temperature sterilization, disinfectant sterilization and so on. Even people can achieve the effect of sterilization and disinfection with boiling water at ordinary times. Ultraviolet UVC is only one of many disinfection and sterilization methods. At present, UVC has not found a very painful and absolutely alternative application, which needs to stand out and still needs to explore a focus.

In industrial or commercial areas:

It is undeniable that compared with ultraviolet mercury lamp, the working efficiency of UVC LED is far less than that of ultraviolet mercury lamp, and the photoelectric conversion efficiency of UVC LED is relatively low, and the technical problems are big; at present, the ultraviolet mercury lamp still occupies the low position of the mainstream.

Therefore, the novel coronavirus pneumonia can only be donated to the UV sterilization mercury lamp in the lamps and lanterns. UVC LED can only emerge in the field of surface sterilization on personal protection.

After the outbreak, there is a chance to solve the above two development problems

1) Obviously, it has solved the problem of cultivation and cognition of the mass market of UV LED for a long time. Previously, it took a long time to educate the market, but little effect was achieved. This time, a huge positive publicity was obtained in the unfortunate accident, which deepened the consumers' understanding of the disinfection and sterilization of UV LED and UV products.

2) Once the public's awareness of UV sterilization is improved, as the industry chain of UVC LED will pay more attention to R & D and promotion, the technology will make a certain breakthrough, and mercury lamp will gradually withdraw from the stage, which will be very conducive to the full market opening of UVC led.

3) UVC LED will be more popular in sterilization, household appliances, consumer water treatment and so on. For example, the discovery of coronavirus on doorknobs in news reports a few days ago has greatly aroused people's awareness of virus prevention in doorknobs and elevators. Although human forgetfulness, inertia, difficult to move, after the epidemic, the importance of sterilization will inevitably decline, but at the same time, it will still cause some people still pay attention to it. In terms of product design, it will be a better choice to put the disinfection and sterilization function of UVC led more on the original household products or matching with daily cleaning products. Such as air conditioning, air purifier, drinking machine, sweeping robot, etc.

4) Under the continuous technological breakthrough, UVC LED is expected to be gradually applied in medical treatment and industrial water treatment. Although UV mercury lamp is still the main one, the development path of UVC LED may refer to the path of LED replacing ordinary lighting, from assisting, imitating and substituting, and then gradually developing UVC LED products with senior characteristics.

In summary, novel coronavirus has made some positive contributions to the fight against ultraviolet products. After the outbreak of the epidemic, UVC LED will also accelerate development to some extent.
