Description

A corridor voice control lamp

technical field

The utility model belongs to the field of corridor lighting, in particular to a corridor voice control lamp.

Background technique

The sound-activated light in the corridor is to use the sound-light control delay switch to replace the switch on the corridor of the residential area. Only after dark, when someone walks through the stair passage and makes footsteps or other sounds, the corridor light will automatically light up to provide lighting. , when people enter the house or walk out of the apartment, the corridor lights will automatically turn off after a few minutes of delay; in the daytime, even if there is sound, the corridor lights will not turn on, which can achieve the purpose of energy saving; voice-activated lights are not only suitable for corridors in residential areas, It is also suitable for public places such as factories, office buildings, and teaching buildings. It has the advantages of small size, beautiful appearance, easy production, and reliable operation. It is suitable for lighting equipment in various building corridors; For triggering, the trigger sensitivity depends on the collection ability of the electret; if the collection area around the electret is blocked by dust, it is difficult to trigger the sound-activated lamp effectively; in addition, it is not suitable for some specific occasions to trigger by sound.
