Ultraviolet UVC-LED disinfection principle:
viruses, all organisms including humans, are composed of cells, whereas viruses are acellular, and are composed primarily of a protein coat and nucleic acids having one or more nucleic acid molecules: DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) make up the genome.
Viruses are replicated by RNA and belong to single-stranded positive-strand RNA viruses, and the ultraviolet disinfection process mainly breaks the nucleic acid (RNA) strand of the virus and destroys the protein layer of the virus, thereby affecting the survival and replication capacity of the virus and causing the death of growing cells and/or regenerative cells. This process is medically known as "inactivation".
Ultraviolet UVC (short wave, wavelength 200-280nm) which can act on the genetic material DNA of organisms and damage the DNA to cause the virus to lose survival and replication ability, destroy the viability from the cell layer and completely kill germs.
The ultraviolet sterilization has the following advantages: 1. high-efficiency sterilization: the sterilization effect of UVC to bacteria and viruses is generally completed within a few seconds, almost instantaneous, and the sterilization and disinfection capacity is 600-3000 times larger than that of chlorine. 2. Broad spectrum sterilization: UVC sterilization the broad spectrum of sterilization is the highest of all current sterilization techniques. It can kill almost all bacteria and viruses with high efficiency. 3. Safety: the ultraviolet lamp emits light with UVC wavelength of 200-280NM to sterilize, the whole sterilizing process does not need to add any chemical agent, does not generate any other chemical pollutants, does not generate ozone and mercury which are harmful to human bodies like a quartz lamp tube, and really achieves safety and environmental protection. 4. No drug resistance: UVC is the direct destruction of DNA, RNA, protein, etc. in bacterial virus cells, leads to the direct death of cells, cannot reproduce and replicate, and has no drug resistance. Other chemical agents can cause bacterial viruses to generate drug resistance when being sterilized, and the sterilization effect of the chemical agents is ineffective. 5. The service life of the UV LED is generally 25,000 hours to 30000 hours, which is more than 10 times of that of the traditional mercury lamp, the energy is saved by 90 percent, and the service life is not influenced by the switching times. 6. Energy is saved, the light conversion rate of the UVLED reaches 48%, the light output is stable, the energy consumption is low, and the power consumption is only 10% of that of the traditional UVLED. 7.
