UV germicidal lamps

The invention relates to a sterilizing lamp, in particular to an ultraviolet sterilizing lamp with lighting function.

Ultraviolet light in sunlight generally refers to invisible light with a wavelength of 200-400nm. According to the wavelength, it is divided into three types: UVA (wavelength 320-400 nm), UVB (wavelength 290-320 nm) and UVC (wavelength 200-290 nm). Among them, UVC can almost be blocked by the atmosphere because of its weak ability to penetrate the atmosphere. Therefore, there are mainly two types of UVA and UVB that have an impact on the human body. However, although UVC has the shortest wavelength, due to its strong energy, for example, ultraviolet light with a wavelength of 254 nanometers (nm) can destroy large biomolecules in the human body, that is, damage living cells, or damage DNA. (DNA) or ribonucleic acid (RNA) bond damage makes it impossible to reproduce, but also can achieve the purpose of sterilization.
