solar street lamp having color control facility

摘要

The present invention relates to a solar street light with a color adjustment function of a light pole. In a solar cell module array in which a plurality of solar cells are connected, solar energy is converted into electrical energy to charge a storage battery. A DC power supplied from the storage battery having an over-discharged or an overcharged state controlled by a charging/discharging control unit turns on a street light via a power supply unit. A controller recognizing a current rain or snow falling state through a rain sensor controls the lighting state of the street light while controlling the power supply unit, and controls the DC power supplied from the power supply unit through a switching element to be selectively supplied to a white light emitting diode array or a yellow light emitting diode. A heating element is heated by the power supplied through the power supply unit under the control of the controller, and the water present in the rain sensor is removed to correctly recognize the rain or snow falling state such that the white light emitting diode array or the yellow light emitting diode array can be accurately turned on.
