Illuminated shelf to charge devices through a solar panel

摘要

This project aims to design a system capable of providing electric power to charge USB devices and illuminate a multipurpose shelf. With a compact and economical design, it is intended for use in public places, like restaurants and pubs. The equipment consists of a solar panel, one battery module, a device whose function is to obtain the maximum power of the solar panel, a management system of batteries aimed distribute energy from the solar panel to the batteries. Also it includes a LED lighting which is controlled by a driver. A control circuit with LDR is responsible for determining when it is necessary to activate the LED light because it has poor lighting, for example at night. In this case the light is activated to 10% of its power, and when someone activates a switch the light will be at full power. During the day the light is not working. When the switch is activated is when you can charge devices through the USB port.
