Let's look at the coronavirus first. Coronavirus belongs to protein-bound single strand positive RNA virus. Previously, six kinds of corona-viruses were known to infect human: α (229E, nl63) and β (OC43, hku1, mersr CoV and SARS CoV). Among them, hku1, mersr CoV and SARS CoV can cause pneumonia. The most well-known are SARS in 2003 and mers in 2012. In terms of the binding strength of virus and re...

Abstract : according to the ultraviolet killing dose of Beta-coronavirus coronavirus, such as SARS and MERS in the literature, the 99.99% lethal ultraviolet dose of 2019-nCovnovel coronavirus NCP with an initial concentration of TCID50 of about 105.8 /mL was given to be 1085 mJ/cm2, and the base model of deep ultraviolet LED with reference to surface antivirus and air purification was provided for...

The use of UV Curing Oven makes the UV glue bonding process of medical device products become automatic and easy. Now, advanced LED UV curing oven can solidify in seconds without adding solvent UV glues and dispensing systems, enabling the medical device assembly process to form consistent and repeatable bonding efficient, economical and convenient methods. The optimization and control of ultravio...

UVC Ultraviolet LED as an alternative to UV mercury lamp in the future, after the plague, the problem of cost reduction and efficiency improvement is more urgent. So, under the influence of the epidemic, does it really help speed up the research and development of the industry? Will the UVC LED industry break out ahead of time this year? Regardless of the background of the epidemic, according to t...

To meet the needs of production development : the original 4-5V power supply can be used to flexibly and reduce the number of modules, increase or decrease the current, and improve the utilization rate of equipment. To improve the reliability of production operation : the professional for LED constant current power supply is designed in N+1 mode. Under normal circumstances, all modules are involve...

Because the constant current source drive, do not need in the output circuit series current limiting resistance, LED through the current is not affected by the external supply voltage change, environmental temperature change, as well as LED parameter dispersion, so that the current can maintain constant, full play of various excellent characteristics of LED. LED constant current power supply is ad...
