The present invention relates to a plastic bottle lamp for day and night using a solar panel. For this, a waste plastic bottle and a waste mobile phone lithium battery are used. A solar cell module and a charge controller are connected to each other and then connected to a charging battery to be charged. A switch is installed to the battery to be used when the electricity is needed. The solar cell module has the maximum voltage of 5V, the maximum current of 116 mA, and the maximum output of 0.58 W. A charger charges a 3.7V/1500 mA lithium battery which is charged for about 10 hours and can be used for about 13 hours. Two LED lamps of maximum 4V/50mA are connected in parallel. The angle of the solar cell module can be controlled in a range of +15 to -15 degrees. The size of the solar cell module is the same as that of the lid of the plastic bottle. So, in the day time, the solar cell module can be safely used even though water is supplied to the plastic bottle. After sunset, the solar cell module can use stored electric charges. |
