Illuminating System for Bus Stand Using Solar Energy

摘要

The present invention relates to a device for converting the energy of light condensed in a solar cell into electrical energy during the day and storing the energy in a battery and then lighting the bus platform with an LED lamp using the power stored in the battery at night. The present invention includes a controller 27 for storing the power generated by the solar cell during the day in the storage battery, and at night send the power stored in the storage battery to the LED lamp to generate light; A solar cell 21 installed on the roof 28 of the platform 20; A storage battery 26 that is converted into electrical energy from the solar cell 21 and stored therein, and is stored in the storage box 25 on the pillar 29 of the landing 20; In the platform lighting apparatus using ordinary sunlight, which is composed of LED lamps 50 to 52 that illuminate by using the electric power stored in the storage battery 26, to prevent overcharging and over-discharge of the storage battery 26. In order to configure an overcharge and overdischarge prevention circuit inside the IC chip, the first detector 41 for measuring the voltage of the storage battery 26 to prevent overcharging, and the third detector 43 for preventing overdischarge; It characterized in that it comprises a second detector 42 is connected to the optical sensor for sensing the intensity of the external light to supply and cut off the LED lamp.;According to the present invention, the power consumption can be reduced because the LED lamp is used. Since the power consumption is very low, the free days have the advantage of operating up to 5 days. Also,. By adopting overcharge and overdischarge control device of battery, it adjusts individual cell voltage of parallel unit built in battery and solves voltage unbalance between cells and can extend battery life by 2 times.;Solar, Cell, LED Lamp, Storage Battery, Overcharge, Over Discharge
