Interpretation of the development status of UVC LED

A New Coronavirus (COVID-19) greatly shortened the UVC LED technology consumer education time. Since last year, products with UVC LED technology have sprung up like mushrooms.

It is understood that under the influence of the epidemic, brand manufacturers' awareness of sterilization and purification has been greatly enhanced. From household appliances disinfection to air sterilization and water purification, UVC LED market demand remains high, driving the development of the overall market scale of UV LED.

However, in terms of the current technical level, UVC LEDs are facing different difficulties in different links of the industrial chain.

Chip is the basis of performance improvement and cost reduction.

Chip is the core difficulty in UVC LED industry chain.

At present, the photoelectric conversion efficiency of UVC LED chips in mass production and circulation on the market is only about 3%. To greatly improve the photoelectric conversion rate, the source lies in the improvement of the chip itself.

Epitaxial chip and chip end are the foundation of the whole UVC LED industry chain. If the performance of the chip is not good, no matter how to improve the structure and technology of the packaging end, it can not fundamentally solve the problem.
