The comparison between traditional black light lamp design and fluorescent lamps only has a few important changes. Fluorescent lamps generate light by passing an electric current through a tube filled with inert gas and a small amount of mercury. When electrified, mercury atoms emit energy in the form of visible photons. They emit some visible photons, but most of them are emitted in the ultraviolet wavelength range. The wavelength of ultraviolet light is too short to be seen. Fluorescent lamps must convert this energy into visible light. To achieve this goal, a phosphorus coating was applied on the outside of the tube.

The carbon dioxide exhaled by humans has been scientifically proven to be a substance that attracts mosquitoes to the human body. The photocatalyst mosquito killer can generate the light, heat, carbon dioxide, water vapor, and flowing air that mosquitoes like during operation, simulating human respiration to lure mosquitoes, attracting them away from their surroundings and falling into the mosquito trap cyclone, causing them to dehydrate and air dry and die. Photocatalysts can also purify air, sterilize and disinfect.
