In view of the overall global development of UVLED technology, this paper makes a simple comparative analysis on the development of LED in China and UVLED abroad

Recently, the application of ultraviolet LED (UVLED) technology in China is relatively rapid. At present, deep ultraviolet LED (UVLED) is mainly used in biomedicine, anti-counterfeiting identification, purification (water, air, etc.), computer data storage, military and other fields. And with the development of technology, new applications will continue to appear to replace the original technology and products, UV LED has a broad market application prospects, such as UVLED lamp phototherapy is a very popular medical device in the future, but the current technology is still in the growth period.

In the face of the development of foreign UVLED related technologies, foreign countries are still in a leading position. For example, Japan, with its first mover advantage in the field of blue LED, has made remarkable progress in UVLED. In particular, Japan Asia company is far ahead in the research of 365 nm UV-LED; The United States is the leader in deep UV research, but it has been surpassed by Japan in recent years; Taiwan and South Korea started relatively late and made some progress in this field; In recent years, this field has developed rapidly in China. Different from Blu ray, UV LED is currently in a period of technological development, with less restrictions on patents and intellectual property rights, which is conducive to occupying and leading the technological commanding heights in the future.

Domestic UV LED equipment, materials and devices have a certain accumulation, is now actively developing to application module. Before UVLED becomes a large-scale industry, it needs the guidance and support of the state in order to get the first chance in the core technology.

The main research goal in the future is to study high quality deep UV material epitaxial growth technology; High Al content AlGaN material growth technology and doping technology; Deep UV LED structure design; The fabrication process and packaging technology of LED chip with wavelength below 300nm; Development and application of UV light source module for medical, sterilization and purification applications.
