The invention discloses an energy-saving control system for a street lamp. The energy-saving control system is characterized by mainly comprising a control chip U1, an infrared sensor U, a capacitor C4, a resistor R1, 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; one end of the resistor R1 is connected with the positive electrode of the capacitor C4 and the other end 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. Therefore, the lighting efficiency of the street lamp can be improved and the electric energy is greatly saved.
Description
technical field [0001] The invention relates to a control system, in particular to an energy-saving control system for street lamps. 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 object of the present invention is to overcome the defects of the existing street lamp control system that the street lamp is turned on even when no pedestrian passes by, which wastes electric energy, and provides an energy-saving control system ...
