Constant voltage source circuit-based energy-saving control system for street lamp

Abstract

The invention discloses a constant voltage source circuit-based energy-saving control system for a street lamp. The constant voltage source circuit-based energy-saving control system is characterized by mainly comprising a control chip U1, an infrared sensor U, a capacitor C4, a constant voltage source circuit, a base trigger circuit and the like, wherein a positive electrode of the capacitor C4 is connected with a power supply and a negative electrode passes through a photo-resistor RL and then is connected with a GND pin of the control chip U1; an input end of the constant voltage source circuit is connected with the positive electrode of the capacitor C4 and an output end passes through a resistor R1 and then is connected with a power supply input end of the infrared sensor U; and the base trigger circuit is connected with the control chip U1. When a pedestrian passes through at night, the street lamp is controlled to be lighted and lights for the pedestrian; after the pedestrian passes through, the street lamp is controlled to be extinguished; and the street lamp is not lighted even if the pedestrian passes through in the daytime. Input voltage can be treated, so that the constant voltage source circuit-based energy-saving control system has stable working voltage and the stability of the constant voltage source circuit-based energy-saving control system is greatly improved.

Description

technical field [0001] The invention relates to a control system, in particular to an energy-saving control system for street lamps based on a voltage-stabilizing source circuit. Background technique [0002] With the development of society, the number of street lamps continues to increase, which brings great convenience to people's lives. At present, street lamps are usually controlled by light control, timing or manual switch. However, when the above methods are used to control street lamps, the street lamps will also be on when no pedestrians pass by. Therefore, the current street lamp lighting is mostly low-efficiency lighting. , and its power utilization rate is low, which cannot meet the energy-saving concept advocated at present. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the existing street lamp control system will turn on the street lamp when there is no pedestrian passing through, which wastes electric ...
