Because the self induction component of the sound control belongs to a mechanical type, the sound control is easily influenced by mechanical fatigue, and the image that the sensitivity is better during initial assembly and the sensitivity is low in later period is difficult to overcome. Therefore, the acousto-optic control switch can be triggered only by artificial noise at the later stage of use, such as coughing at loud voice or stomping at a stom that the lamp is required to be on obviously disturbing other people, and particularly influencing sleeping people at night. In addition, the sound and light control is easy to respond to all larger sounds (such as thunder, automobile horn sound, engine sound when an automobile passes by, electric drill sound for decorating rooms, door opening and closing antitheft sound and the like) in the nature, and the misoperation is more.
