Light emitting lock

A light emitting lock comprises a lock body, a lock head installed on the lock body and a lock cylinder installed in the lock body. The light emitting lock further comprises a plurality of fluorescent rings which are arranged on the surface of the lock body and surround the lock cylinder. Each fluorescent ring comprises a core shaft made of elastic materials and a self-light-emitting wire wound on the core shaft. The fluorescent rings are arranged on the light emitting lock and can emit light at night or in the dark, unlocking is convenient, the staying time at a doorway is shortened, and potential safety hazards are reduced. In addition, the fluorescent rings are composed of the elastic core shafts and the self-light-emitting wires wound on the core shafts, and therefore the fluorescent rings are convenient to manufacture and can be arranged on the lock body conveniently.
