Editorial Note 2016100459 There are 3 pages of Description A solar underground LED lawn lamp Technical field This utility model relates to a solar underground LED lawn lamp. Background technology The lawn lamp is a common park decoration facility. It can not just provide illumination, but also beautify the park. However, the overall heat dissipation performance of lawn lamp is poor, since it is buried under the ground. Because it can be directly contacted, it is often stolen. These increase maintenance cost. Invention content The technical problem to be solved by this utility model is to provide a solar underground LED lawn lamp. After this device is installed, the guard plate can be located by the cooling water pipe. The guard plate can effectively avoid disassembly and stealing of this device. Besides, the cooling water pipe couples with the heat conduction pipe. The heat generated by LED light sources can be taken away by the heat conduction pipe to avoid too high temperature and extend the service life of this device. Besides, it is powered by solar energy, so it is energy-saving and environmentally friendly. To solve the above problem, this utility model adopts the following technical proposal: A solar underground LED lawn lamp includes 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. The cooling water pipe and the pipe joint forms sealing. Helical heat conduction pipe is set at the bottom of noumenon. The heat conduction pipe extends in the noumenon. The heat conduction pipe leans against the PCB circuit board. Solar photovoltaic panel is set at the edge of top of noumenon. Accumulator and inverter are set at the bottom of noumenon near both sides of guard plates. The solar photovoltaic panel, inverter and accumulator are electrically connected in proper order. Optimally, the guard plate and the noumenon are connected fixedly. The thickness of guard plate is 3mm-8mm. Optimally, the cooling water pipe is made of copper or aluminum. The wall thickness of cooling water pipe is lmm-1.5mm. Optimally, the heat conduction pipe is a hollow pipe. The wall thickness of heat conduction pipe is 0.5mm-lmm.
