The solar mosquito killer lamp uses high-tech technology to convert light energy into electric energy and stores it in a built-in rechargeable battery. The light source uses an ultra-high-brightness LED lamp with automatic light sensing function, and automatically turns off the light to work in daylight. The wavelength generated by the purple light has strong light-trending, wave-tiding, color-changing, and tropism characteristics and principles for mosquitoes and insects. Determine the induction wavelength for mosquitoes. Use low-temperature plasma generated by discharge and ultraviolet radiation The phototaxis and excitement effect produced by the pests induces the insects to pounce on the light source of the lamp, and the high-voltage kill net is disposed outside the light source to kill the pests, thereby achieving the purpose of killing the pests.
