Brighten the dark / backpack

Brighten the dark

According to the survey, most of the impoverished mountain areas often suffer from power instability and sudden power outages. At this time, they can only use kerosene or candle lighting. The burning of kerosene lamps will not only pollute the environment, but also easily cause fires. The weak lights are also a great damage to children's eyesight. This backpack is stored by absorbing light energy and can be illuminated by rolling up solar panels at night. When the children return home, put down their school bags, roll up the solar panels, and take out their homework, this series of unconscious actions completes the turning on of the lamp.
