Based on children's fear of darkness, a nightlight for children is designed. The shape of the lamp is inspired by the shape of small animals, which is in line with the preferences of children, and also attracts children's attention through this shape. The main function of this nightlight is to accompany the child to sleep. The nightlight can set the time and gradually extinguish after the child falls asleep. At the same time, it also has a sensing function to facilitate the child to get up at night and avoid bumping. In addition to being used as an auxiliary lighting at night, the night light can also be used for decoration.
