The invention relates to the field of LED (light-emitting diode) floodlights and in particular relates to an inducting solar lawn lamp comprising a base, a lamp body and a solar panel. The inducting solar lawn lamp is characterized by also comprising a low-luminance LED light source, a high-luminance LED light source, a controller, a storage battery and an infrared detector, wherein the low-luminance LED light source and the high-luminance LED light source are positioned in the lamp body; the infrared detector is embedded on the outer surface of the lamp body; the solar panel is respectively electrically connected with the controller and the input end of the storage battery; the infrared detector is connected with the input end of the controller; the output end of the controller is respectively electrically connected with the low-luminance LED light source and the high-luminance LED light source; and the infrared detector is connected with the high-luminance LED light source by virtue of the controller. The inducting solar lawn lamp has the beneficial effect that only the low-luminance LED light source works when all is quiet in the dead of night; when a person walks, the high-luminance LED light source works, thus the electric energy of a storage battery is saved and the luminescence time is prolonged; and when the storage battery is used up, an external source can be used for lighting.
