The utility model refers to the field of lighting lamps, in particular to a kind of continuous disinfection lighting lamp.
White light, a kind of natural light, is essentially an electromagnetic wave. Newton's prism experiment shows that white light can be decomposed into color light band. The color is red, orange, yellow, green, cyan, blue and purple. The range of spectrum is actually the range of electromagnetic waves. The spectrum range of the whole electromagnetic wave is huge, but the range of visible light is very small. It is found that the visible light region is in the wavelength range of 390-770 nm, and other spectra are invisible to human eyes. Electromagnetic wave, which is derived from the perpendicular electric and magnetic fields with the same phase in space, is an electromagnetic field propagating in the form of wave, with wave particle duality. The direction of electric field, magnetic field and propagation of electromagnetic wave are perpendicular to each other, so electromagnetic wave is transverse wave. When the energy level transitions beyond the critical point of radiation, the electromagnetic wave radiates outward in the form of light. At this stage, the wave body is photon. When the frequency of each band is arranged from low to high, they are radio wave, microwave, infrared ray, visible light, ultraviolet ray, X-ray and y ray. The three primary colors of light are red, green and blue. The combination of these three lights can produce the light of other colors, including white light. The effective wavelength range of ultraviolet disinfection can be divided into four different bands: UVA (400˜315 nm), UVB (315˜280 nm), UVC (280˜200 nm) and vacuum ultraviolet (200˜100 nm). Among them, only the parts of UVA and UVB can reach the earth's surface through ozone protection layer and cloud layer. In terms of sterilization rate, UVC is in the range of microbial absorption peak, which can kill viruses and bacteria by destroying the DNA structure of microorganisms within 1 s, while UVA and UVB are very slow because they are outside the range of microbial absorption peak, so it often takes several hours to kill bacteria. Ultraviolet radiation mainly damages microorganisms (bacteria, viruses, fungi and other pathogens) and destroys the function of nucleic acid to kill microorganisms, so as to achieve the purpose of disinfection. The effect of ultraviolet radiation on nucleic acid can lead to the breaking of bonds and chains, crosslinking between strands and the formation of photochemical products, which changes the biological activity of DNA and makes microorganisms unable to replicate themselves. This ultraviolet damage is also lethal damage. However, ultraviolet rays are also harmful to human body. Therefore, it is not suitable for human beings or animals to be present where there is ultraviolet radiation.
The electromagnetic wave with the wavelength of 207 nm to 222 nm constitutes a part of UVC, which is far ultraviolet (Far UVC) and stronger than traditional UVC for disinfection. Its disinfection is physical disinfection, without secondary pollution, and harmless to the environment, ecology and human beings. It can perform disinfection as fast as traditional UVC, and it will not harm human beings. This is the main reason why we invented lamps with continuous disinfection function.
