1. Performance improvement and cost reduction are the core elements of large-scale application of UV LED
On the one hand, make full use of my country's industry organization advantages in the field of semiconductor lighting, build a public platform, and jointly overcome key common technical problems with enterprises, universities and research institutions; on the other hand, aim at high light efficiency, high power, high reliability and other goals, and enhance the R&D capabilities of chip companies. At the same time, for system-level products, actively accelerate the development of UVC LED devices and modules, and develop UV-resistant, high-temperature resistant, high UV transmittance, high refractive index optical filling, high performance, low-cost packaging materials.
2. Deepen the research on UV LED phototherapy and sterilization mechanism
Through self-construction and joint construction by enterprises, organize relevant research institutions and medical institutions to strengthen the systematic research of UV LED in the fields of bone diseases, skin diseases, and diagnosis, as well as the research on the safe dose of UVC LED of different wavelengths to the human body; reveal the cell biological effects and action mechanisms of ultraviolet rays of different wavelengths, optimize the effective parameters of UV LED sterilization and disinfection applications: wavelength, power density, irradiation dose, etc., develop corresponding equipment, and support pilot demonstration applications.
3. Improve relevant standards and testing systems
First, strengthen the construction of the standard system and give full play to the role of industry organizations in promoting standards. It is recommended that semiconductor lighting related industry organizations jointly with upstream and downstream enterprises compile relevant group standards, strengthen standard promotion, and make them rise to national standards and industry standards; encourage enterprises to actively participate in the construction of local standards. Secondly, improve the measurement and testing methods. Before the registration of the health and disinfection certificate, ultraviolet disinfection products need to be evaluated by a testing agency with relevant qualifications. At present, the testing methods and measurement methods are not unified, which is not conducive to the scientific evaluation of the sterilization and disinfection effect. The solution to these problems requires further capacity building of metrology agencies and testing equipment companies, including the application of AlGaN ultraviolet photodetectors based on wide bandgap semiconductor materials that only respond to the UVC band. Furthermore, the number of units that optimize sterilization and disinfection detection capabilities and establish UV LED device/light source testing capabilities is still small. At the same time, the sterilization and disinfection effect evaluation agency still lacks understanding of UVC LED, and the industry urgently needs testing agencies with both UVC LED and microbial testing capabilities. It is recommended that relevant national departments set up authoritative disinfection product testing agencies to form an industrial foundation platform in the field of disinfection to better assist the standardized development of the industry.
4. Strengthen intellectual property protection
While strengthening core technologies, UV LED-related enterprises should pay attention to the layout of related application patents. Strive for intellectual property funding policies, and suggest that industry associations jointly establish public technology research and development platforms with enterprises, universities and research institutes, build UV LED patent databases, and provide public services such as query, retrieval, statistics, analysis and early warning. Strengthen the training of UV LED intellectual property talents, jointly build UV LED intellectual property training bases with professional intellectual property service agencies, and carry out professional intellectual property talent training. Promote in-depth cooperation between enterprises and scientific research institutions, universities, and intellectual property service agencies to form high-value patent portfolios, promote the industrialization transfer of UV LED technology in scientific research institutions, and effectively improve the level of industrialization of research results.
5. Promote cross-field industrial chain cooperation
Industry organizations should continue to carry out UV LED industry research to support enterprises in the industry to layout UV LED sub-sectors, increase investment in UV LED products in an orderly manner, and solve UV LED product and application technology problems. For specific application scenarios, such as cold chain production, transportation, sales, storage and other links of meat, aquatic products, soy products, etc., for dark, closed, humid and other spaces where microorganisms are easy to breed, take advantage of the small size and easy industrial design of LED, and jointly develop and verify new applications and new products with upstream and downstream companies. Encourage relevant enterprises to improve product quality and intelligence level based on rich market channels, and integrate functions such as personnel infrared detection, light output ultraviolet monitoring, timed switch voice reminder, and high-intensity visible/blue light assistance.
6. Promote UV LED demonstration application
UV LED companies should study the key integrated technologies such as light distribution, mechanics, electrical, and heat dissipation of UV LED modules and light sources under different scenarios, and form safe and reliable intelligent solutions; relevant departments of local governments can rely on the background of normalized epidemic prevention and control to carry out key demonstration applications, and through "government-enterprise-university-research" cooperation, cultivate the UVC LED application market, promote the improvement of technical level in application, standardize standards and product use effects, optimize solutions, etc., so as to drive market demand and promote the transformation of scientific and technological achievements through application demonstration.
