PURPOSE: A safety system for a bus station based on a solar cell is provided to easily increase the generation capacity of an existing solar cell by simply installing an expansion module on a main panel. CONSTITUTION: A safety system for a bus station based on a solar cell comprises an LED lighting unit(160), one or more human body sensors(120), an LED lamp(170), a controller(150), and a solar cell(100). The LED lighting unit lights the inside a bus station. The human body sensors detect whether persons exist in the bus station or not. The illumination sensor The LED lamp emits light when the persons exist in the bus station. The controller controls the operation of the LED lamp based on the signals inputted from the human body sensors. The solar cell is installed on the bus station to supply power to the LED lighting unit, the human body sensors, the LED lamp, and the controller. |
