Streetlamp controller capable of changing lights in delayed manner through human body induction and used in parks

Abstract

The invention provides a streetlamp controller capable of changing lights in a delayed manner through human body induction and used in parks. The streetlamp controller is characterized by comprising a 220V alternating current power supply, a 12V half-wave rectification voltage-stabilizing power supply, a microwave induction circuit, a signal identification and amplifying circuit and a level signal delaying and incandescent light bulb driving circuit, wherein a microwave induction module IC1 in the microwave induction circuit adopts the type of TWH9428; and the integrated circuit IC2 in the signal identification and amplifying circuit adopts the type of TWH9429. For overcoming the problem of waste of energy of common streetlamps existing in public places, such as parks, gardens, scenery sites of river sides and lakesides, and the like, the streetlamp controller adopts the microwave induction control mode; the streetlamp controller inducts distance through human body induction; the streetlamp controller lightens an illuminating streetlamp automatically when a human body is approaching; the streetlamp is delayed for a while and changed from a full-bright state into a dark-bright state automatically after the human body is far from the streetlamp for a certain distance; and therefore, electrical energy can be effectively saved.

Description

Technical field [0001] The invention belongs to the field of electronics and energy saving technology, and relates to a human body induction delay dimming street lamp controller in a park amusement park. Background technique [0002] With the continuous advancement of urban beautification and lighting, many roads in public places such as parks, amusement parks, rivers and lakes landscape areas have been installed with various lights to facilitate tourists and pedestrians to play or watch. Every night the lights in these public places are all turned on, which is really convenient when there are tourists, but in the middle of the night when there are few or very few tourists, the lights cannot be turned off. Most of the various lights They are all on all night long, which causes a huge waste of energy. [0003] In order to overcome the problem of energy waste of ordinary street lamps in the above places, the human body induction delay dimming street lamp controller of the park amuse...
