This utility model discloses a light-control underground LED lawn lamp, including the noumenon. PCB circuit board is set in the noumenon. LED light sources are evenly distributed on the PCB circuit board. Two guard plates are symmetrically set at the bottom of noumenon. The guard plate has through-hole. The through-holes of two guard plates face each other. Cooling water pipe is set between the two through-holes. Flexible pipe fits at both ends of cooling water pipe. The flexible pipe has pipe joint. Helical heat conduction pipe is set at the bottom of noumenon. The heat conduction pipe leans against the PCB circuit board. Light control module is set on the noumenon between the two guard plates. Light control sensor is set at both sides of top of noumenon. The light control sensor is electrically connected with the light control module. The light control module, PCB circuit board and LED light sources are electrically connected in proper order. The structure of this device is simple, and its cost is low, so it is suitable for promotion. -- ---- ---- -- |
