Bicycle lamp storing electric energy by utilizing solar cell

The invention provides a bicycle lamp storing electric energy by utilizing a solar cell. The bicycle lamp comprises a solar cell mounted on a bicycle, the solar cell is provided with an energy storage box, the energy storage box is provided with an electrode, and an external bicycle lamp is connected with the electrode. According to the bicycle lamp, the problems that at present, a cell used for a bicycle lamp is small in electricity storage capacity, no reminding on electric quantity reduction or the fact that the electric quantity is about to be used up is available, and the cell cannot be recycled are solved. The usage rate of the bicycle lamp cell is improved, the cost is reduced, and convenience and comfortable riding experience are provided for bicycle riders. 本发明提供了种利用太阳能电池存储电能的自行车车灯，包括安装在自行车上的太阳能电池，所述太阳能电池设有储能盒，所述储能盒上设置有电极，外部自行车车灯连接所述电极。本发明解决了目前自行车车灯所用电池储存电量小，没有电量减少或即将用光电量的提醒，且不能重复利用的问题，提高自行车车灯电池的使用率，降低成本，为自行车车友提供方便和舒适的骑行体验。
