Description
Technical field
The invention belongs to Electronic Control and power-saving technique field, relate to a kind of human body induction type delayed lamp controller.
Background technology
Various delay illuminating lamp has all been installed in the public places such as the corridor in a lot of building, as: sound control delay switch uses really easily, can reach the object of energy savings.But also things turn out contrary to one's wishes sometimes, the circuit of this audio-switch is very sensitive, around slightly the sound will action, such as: ambient room enabling, the sound of closing the door, near sound, even downstairs the vehicle whistle sound etc. of setting off firecrackers, capital makes Acoustic controlled light light, not only can not economize on electricity, and also can have influence on the useful life of illuminating lamp because of frequent bright light.Especially, when evening, night was by corridor for you, rely on the sound control road lamp that sound is lighted, people must produce the sound for stamping one's foot or clapping the hands, this sound control road lamp hinders the peacefulness at night really.
