Aldehyde antibacterial lamp is a device that uses ultraviolet radiation to kill or inhibit bacteria, viruses, and fungi. Its working principle is mainly to destroy the nucleic acid of bacteria and viruses through ultraviolet radiation, thereby inhibiting the growth and reproductive ability of bacteria, viruses, and fungi. Below, we will provide a detailed introduction to the working principle of aldehyde antibacterial lamps.

Xinjiang formaldehyde removal and antibacterial lamps usually use ultraviolet C-band (UVC) radiation for disinfection. The UVC band has a shorter wavelength, high energy, and strong bactericidal ability. Its wavelength range is 100-280 nanometers, while the visible light wavelength is 380-780 nanometers, so we cannot directly see UVC light.

Xinjiang formaldehyde removal and antibacterial lamps usually have a light source called a mercury lamp installed inside, which contains a small amount of mercury and inert gas. When an electric current passes through a mercury lamp, the generated arc emits radiation from the mercury vapor, including visible and ultraviolet light.

When an arc is generated, the aldehyde antibacterial lamp will release UVC light. This type of light can penetrate the shells of bacteria, viruses, and fungi and enter their nuclei. In the nucleus, UVC light interacts with DNA and RNA, disrupting their structure and function, thereby preventing the growth and reproduction of bacteria and viruses. In addition, UVC light can also damage the protein and enzyme systems of bacteria and viruses, causing them to lose their vitality.

It should be noted that aldehyde antibacterial lamps usually do not directly kill all bacteria and viruses, but rather exert antibacterial effects by inhibiting their growth and reproductive ability, reducing their quantity. In addition, it is necessary to determine the appropriate UVC wavelength and irradiation dose based on different bacteria and viruses to ensure sterilization effectiveness.

In addition to the action of UVC light, aldehyde antibacterial lamps can also produce ozone (O3), which has strong oxidation ability and can further kill bacteria, viruses, and fungi. After contact with bacteria and viruses, ozone can damage their cell membranes and walls, leading to their death. However, ozone has a certain toxic effect on the human body, so it is necessary to pay attention to the reasonable control of ozone production and release when using aldehyde antibacterial lamps.

Overall, the working principle of aldehyde antibacterial lamps is to use the radiation of UVC light and the oxidation of ozone to inhibit the growth and reproductive ability of bacteria, viruses, and fungi, thereby achieving disinfection and antibacterial effects. Aldehyde antibacterial lamps have been widely used in medical, food processing, water treatment, air purification and other fields, making important contributions to protecting people's health and safety.
