On February 20th, according to foreign media reports, industry sources said that due to the increasing demand for disinfection applications due to the new coronavirus pandemic, the supply of high-end UV-C LED chips is tight.
Since the end of 2019, the new crown pneumonia epidemic has lasted for more than a year, and it is still unknown how long it will continue in the future. In addition to health measures such as wearing masks, disinfection, and maintaining social distancing, light of the appropriate wavelength will also make a great contribution to fighting the virus within a certain space. It is reported that UV-C light can destroy up to 99.9% of viruses and bacteria.
According to reports, before the outbreak of the new crown epidemic, due to high cost and low power conversion, UV-C LEDs were far less used in disinfection than UV mercury lamps. However, after the outbreak of the new crown epidemic, the global demand for UV-C LED disinfection applications has been stimulated, and this demand is expected to continue until 2022.
According to sources, international suppliers such as Osram Opto Semiconductors and Nichia are not willing to sell UV-C LED chips separately, but are more willing to sell packaged UV-C LED equipment to increase gross profit margins. .
Sources previously revealed that in the first half of 2020, the revenue of many LED manufacturers' UV-C LED chips/equipment increased by more than 300% year-on-year, and some manufacturers even increased by 700%-800%.
