What Is the Principle of Anion Air Purification Lamp?

The principle of anion air purification lamp mainly involves the process of negative ion generation and air purification.

1. Negative ion generation

High voltage electric field effect: An anion air purification lamp is equipped with a negative ion generator, which can generate an electric field by applying high voltage. Under the action of the high voltage electric field, the molecules or atoms in the air are ionized to form negatively charged ions, that is, negative ions.

Electrode design: Generally speaking, the negative ion generator contains two high-voltage electrodes, which are designed with a specific layout and spacing to optimize the generation efficiency of negative ions. The electrodes are installed in the fan assembly, and the rotation of the fan promotes air flow, so that more air molecules can be exposed to the high voltage electric field, increasing the generation of negative ions.

2. Air purification

Negative ions combine with pollutants: The generated negative ions float in the air and combine with suspended particles (such as PM2.5, PM10, dust, etc.), harmful gases (such as formaldehyde, benzene, etc.) and microorganisms such as bacteria and viruses in the air. The excess electrons carried by negative ions can neutralize the positive charges carried by these pollutants, making them inactive and aggregated into larger particles, which are convenient for subsequent treatment or natural sedimentation.

Pollutant removal: The combined pollutant particles will naturally settle to the ground or the surface of objects due to the increase in weight, thus reducing the concentration of pollutants in the air. Some anion air purification lamp are also equipped with dust collection devices to collect and process these settled pollutant particles.

Antibacterial effect: Negative ions can also destroy the cell structure of microorganisms such as bacteria and viruses, inhibit their growth and reproduction, thereby achieving antibacterial and sterilization effects.

In summary, the working principle of anion air purification lamp is to generate negative ions through a high-voltage electric field, and use the characteristics of negative ions to combine with pollutants in the air, so that they lose their activity and settle or are collected and processed. At the same time, negative ions also have an antibacterial effect, which can effectively improve the air quality. This purification method has the advantages of high efficiency, environmental protection, and no secondary pollution, and is widely used in the field of air purification in homes, offices, hospitals and other places.
