Abstract

The present application discloses an elongated illuminant storage device, including: a reel rotatable about an axis thereof; a spiral spring energy storage member connected to the reel and configured to store a potential energy generated during rotation of the reel; an elongated illuminant made of a flexible material, wound on the reel, and having one end fixedly connected to the reel and the other end being a free end, where when an outward pulling force is applied to the free end, the elongated illuminant is capable of being pulled out, and the reel is driven to rotate, in this case, the spiral spring energy storage member stores the potential energy generated during rotation of the reel, and when the pulling force is removed, the spiral spring energy storage member causes the reel to rotate reversely by means of the stored potential energy.
