Description

Technical Field

[0001] The present invention relates to the field of lighting fixtures, and in particular to an intelligent germicidal downlight. Background Art

[0002] When organic pollutants pass through the ultraviolet irradiation area, ultraviolet rays will penetrate the cell membrane and cell nucleus of the organism, destroy the molecular bonds of DNA, produce pyrimidine dimers in the DNA molecules, induce mutations, and inactivate the cell's genetic material, and the microorganisms will soon die.

[0003] Indoor air disinfection machines have a cumulative effect on microorganisms that pass through their irradiation range, that is, microorganisms that are not killed in the first pass through the ultraviolet irradiation area will be killed in subsequent cycles.

[0004] UV rays destroy the ability of organisms to reproduce, which is very important. Because a bacterium can multiply into hundreds, thousands or even millions of bacteria in 24 hours, this also means that even the most effective air filters cannot completely remove microorganisms, so using UV rays to sterilize is the fundamental solution. The dose required for a microorganism to be killed by UV rays depends on the intensity of the UV light and the exposure time.

[0005] Humans have long manufactured ultraviolet disinfection lamps based on the recognized ultraviolet sterilization principle, which are widely used in air disinfection. As we all know, ultraviolet radiation is extremely harmful to the human body and should be used when no one is around. It is very practical to provide an ultraviolet disinfection lamp that can be powered off when there are people and powered on when there are no people. In addition, it is unnecessary to sterilize in an environment that is not suitable for the survival of microorganisms. Therefore, it is necessary to judge the appropriate time to work.
