Sound and light control street lamp circuit

Abstract

Disclosed is an acoustic-optical controlled streetlamp circuit. An output end of an acoustic sensing circuit (1) and an output end of an optical sensing circuit (2) are respectively electrically connected with an input end of an amplitude two-and circuit (3). An output end of the amplitude two-and circuit (3) is electrically connected with an input end of a time delay circuit (4), an output end of the time delay circuit (4) and an input end of a switching circuit (5) sequentially. A power control output end of the switching circuit (5) is electrically connected with a receiving end of an LED light emitting circuit (6) and a receiving end of a voltage stabilizing circuit (7) sequentially. A voltage-stabilized power output end of the voltage stabilizing circuit (7) is respectively electrically connected with a receiving end of the acoustic sensing circuit (1), a receiving end of the optical sensing circuit (2), a receiving end of the amplitude two-and circuit (3), a receiving end of the time delay circuit (4) and a receiving end of the switching circuit (5). A power output end of a limiting and rectifying circuit (8) is electrically connected with the power control output end of the switching circuit (5). Accordingly, control equipment for the streetlamp circuit is simplified, and the defect that a bulb is easy to damage and electric power is easy to waste due to the fact that the streetlamp is still lighted even when lighting is not needed is overcome.

Description

technical field [0001] The invention relates to a light-controlled street lamp, in particular to an acousto-optic control street lamp circuit controlled by sound and light. Background technique [0002] At present, the well-known national patents 201010123540.0 "Integrated Light Control Lamp" and 201020503356.4 "Light Control Lamp" only have light control and no sound control. At night, this kind of light is used to illuminate pedestrians on the road, but there are no pedestrians passing under this light for a large number of hours. When no pedestrians pass under this light, the road does not need to be illuminated, because this kind of light is a Continuous lighting, so there is the disadvantage of continuing to light the lighting when the lighting is not needed, and easily damaging the bulb and wasting electric energy. Contents of the invention [0003] In order to overcome the disadvantages that the existing light-controlled lamps are easy to damage the light bulbs and...
