Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of street lamp control, and particularly relates to an adaptive dimming LED street lamp for a low-carbon and environmentally friendly smart city and a control method therefor. Background Art
[0002] As a typical representative of a new type of green light source, LED street lamps are widely used in fields such as general lighting, road lighting, and special lighting. Traditional LED street lamps cannot meet the actual lighting needs and consume and waste a large part of the energy. The core goal of an intelligent induction street lamp system is to achieve intelligent management and control of street lamps through Internet of Things technology, so as to achieve the purposes of energy conservation and emission reduction, improving lighting efficiency, and user experience.
[0003] Prior Art One, a Chinese patent, application number: 202321197283.4 discloses an LED street lamp capable of self-inductive control, belonging to the technical field of LED lighting fixtures, including an induction device electrically connected to the signal end of a control device. The input end and output end of the control device are respectively electrically connected to the output end of a signal device and the dimming control end of a dimming power supply. The input end of the signal device is electrically connected to the input end of the dimming power supply through a wiring terminal. The output end of the dimming power supply is electrically connected to an LED light source. The control device is electrically connected to the wiring terminal, and the wiring terminal is electrically connected to a municipal power supply network. It discloses an LED street lamp capable of self-inductive control, which has a simple structure. While saving energy with the LED light source, when the induction device fails to detect no people and vehicles on the road. Although the signal device and the dimming power supply cooperate to automatically reduce the brightness to reduce energy consumption, the problem of unnecessary energy consumption exists in the way of staying lit all night; however, the remote control and monitoring capabilities are insufficient.
[0004] Prior Art Two, a Chinese patent, application number: 202323314782.X relates to the field of street lamp control, and specifically relates to a control circuit for an inductive energy-saving LED street lamp, including a driving power supply, a controller, and a motion sensor. When the target section is in a low-traffic period at night, the sensor control circuit controls the motion sensor to be powered on; the motion sensor is signal-connected to the driving power supply. When the motion sensor detects a moving object, it controls the LED lamp to resume from the energy-saving working mode to the normal working mode and delays switching back to the energy-saving working mode. After the street lamps are lit for a period of time, the working states of all street lamps are switched to the energy-saving working mode. When a moving object appears in the target section, the working states of the street lamps in that section are temporarily switched to the normal working mode. Although, to ensure the lighting demand in this section at this time, the waste of electric power resources is greatly reduced. However, there is a lack of an integrated management platform and it is impossible to achieve global monitoring and management of all street lamps.
[0005] Prior Art Three, a Chinese patent with the application number 202311662254.5, relates to the field of street lamp control technology. Specifically, it relates to a time-sharing control method for an inductive energy-saving LED street lamp, which includes the following steps: setting the lighting time T1 and the extinguishing time T2; calculating the time control period of the street lamp; where T3 and T4 are respectively the preset lighting delay time and extinguishing delay time; within the brightness regulation period, lower the brightness of all street lamps on the target road section; during the brightness regulation period, detect whether there are moving objects on the road surface of the target road section. When the street lamp is in the lit working state, set the street lamps on the whole road section to the energy-saving working mode with low brightness during the low traffic volume period. Although, when a vehicle or other moving object passes by, temporarily set the street lamps on the road section where the vehicle or moving object passes to the normal working mode with high brightness, which greatly reduces the waste of electric power resources; however, the degree of intelligence is relatively low and it cannot flexibly meet the requirements of complex environmental changes.
[0006] Currently, Prior Art One, Prior Art Two, and Prior Art Three have problems such as insufficient remote control and monitoring capabilities, lack of a comprehensive management platform, inability to achieve global monitoring and management of all street lamps, relatively low degree of intelligence, and inability to flexibly meet the requirements of complex environmental changes.
