E-hat / E-hat


In order to solve the problem of students' inconvenience in studying at night in energy shortage poor areas, a new energy cap that uses solar power to illuminate led lights for students to read and read at night is redesigned in conjunction with the daily activities of students. A solar power generation board is designed on the top of the cap, which can be used to charge and store the battery when young people wear a hat to go to school. There is a circle of LED lights under the brim for nighttime lighting.The hat has a similar appearance to a lamp shade. When teenagers go to school during the day, the battery can be used as a lamp at night .
