Novel coronavirus (2019-nCov) has been rapidly spread by the US aviation authority Airport-technology, and the major airports in the United States have upgraded monitoring and prevention measures. Recently, Los Angeles International Airport (LAX), San Francisco International Airport (SFO) and New York John F. Kennedy International Airport (JFK) have launched the UVC ultraviolet disinfection robot of dimer UVC innovations company of the United States to conduct comprehensive sterilization and disinfection on all aircraft cabins entering and leaving the port, so as to effectively prevent the spread of new type of anti coronavirus (2019-ncov).

The novel coronavirus (2019-nCov) is also robust to human transmission, high infection rate, air transmission and variability. If it survives in the air for 30 minutes, it will last 28 days in low humidity environment (such as commercial aircraft). This has brought great challenges and threats to the safety of public transport such as airplanes and trains with dense crowds and airtight environment.

Dimer UVC innovations is a professional disinfection system provider for the aerospace industry in the United States. The system, called germfalcon, is designed to enhance the health of the entire aircraft industry. Germfalcon system uses UVC ultraviolet to eliminate viruses, bacteria and superbacteria on the surface of the aircraft cabin and in the air. The overall design of the system makes all surfaces of the aircraft cabin exposed to sterilized UVC light. The core light source uses gallium nitride (GAN) ultraviolet LED technology, which makes the robot have the advantages of light weight, low power consumption, controllable and adjustable emission band (harmless to human body) 。 "Coronavirus is a dangerous and life-threatening virus," said Elliot kreitenberg, co-founder of dimer. We have to work to eliminate the potential threat of the virus infecting innocent passengers on the plane. Germfalcon is a quick and effective response to this threat and we are pleased to contribute to the emergency response at LAX, SFO and JFK airports during this crisis. "

In contrast, in China, a large proportion of the confirmed patients were infected in the process of taking public transport such as airplanes and trains. It can be seen that it is urgent for China to increase the provision of disinfection equipment and facilities in public places, such as public transport, with reference to developed countries. Compared with developed countries, China's attention and investment in public health is far from enough. It can be predicted that with the outbreak as a warning, China will increase investment in the follow-up public health and epidemic prevention and control, which will bring new development opportunities to the enterprises engaged in the original research and development of the third generation semiconductor aluminum nitride (AlGaN) ultraviolet LED and detector chip.

Gallium aluminum nitride (AlGaN) is a good material for the preparation of UV devices due to its high frequency characteristics. UV optoelectronic chips have a wide range of dual-use prospects. In the military field, typical military applications are: fire suppression and explosion suppression system (ground tanks, armored vehicles, ships and aircraft), UV guidance, UV warning, UV communication, UV search and rescue positioning, aircraft landing (land) guidance, space detection, nuclear radiation and biological warfare agent monitoring, explosive detection, etc. In the civil field, the typical applications are: flame detection, corona discharge detection, medical monitoring and diagnosis, water quality monitoring, atmospheric monitoring, criminal biological detection, etc.
