PURPOSE: By providing the electrical energy which the street light using the light emitting diode lights the light emitting diode by using the solar energy. The consumption of the common electricity is saved. CONSTITUTION: The pillar(100) is perpendicularly installed in the surface. The lighting part(200) comprises the base installed at pillar, the emitting device, the heat-sinking member, cover and cover. The angle control member for controlling the angle of the lighting part locates between pillar and base. It is formed into the metal material with a superior heat-sinking member is the thermal conductivity. The power supply unit(300) comprises collimator, the storage battery, and the common power part and converter. |
