The basic structure of mosquito killing lamps is composed of components such as ultraviolet fluorescent tubes, high-voltage power grids, printed circuit boards (mainly containing voltage doubling rectifier circuits), and fence shaped plastic shells. The ultraviolet fluorescent tube is located in the center of the plastic shell and surrounded by a high-voltage power grid. This way, when mosquitoes fly towards the ultraviolet fluorescent tube due to phototaxis, they will be killed by the high-voltage power grid on the way, achieving the goal of mosquito control.
