[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0024] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0025] like Figure 1-3 As shown, a brightness dimming device for urban lighting street lamps includes a box body 1, the box body 1 is embedded in a street lamp pole 2, an information collection unit 3 is fixedly arranged on the front of the box body 1, a timer 4 and a street lamp brightness adjustment unit are fixedly arranged in the box body 1, and the street lamp brightness adjustment unit includes a controller 5 and a processor 6, the information collection unit 3 and the timer 4 are electrically connected to the signal input end of the processor 6, the signal output end of the processor 6 is electrically connected to the controller 5, and the controller 5 adjusts the brightness of the street lamp according to the adjustment signal transmitted by the processor 6.

[0026] The information collection unit 3 includes a light sensor and a pedestrian heat source sensing component, which are electrically connected to the processor 6 respectively. The light sensor is used to obtain the light intensity information of the surrounding environment of the street lamp and transmit the light intensity information to the processor. The pedestrian heat source sensing component is used to detect the pedestrian information within the range of the street lamp and send the pedestrian information to the processor.

[0027] The pedestrian heat source sensing component includes an infrared human body sensor and a laser sensor, which are electrically connected to the processor 6 respectively. The infrared human body sensor is used to detect whether a pedestrian passes by, and the laser sensor is used to detect whether a pedestrian is within the lighting range of a street lamp.

[0028] The working principle of the above technical solution is:

[0029] The timer 4 records the date and the sunrise and sunset times corresponding to each date, sends light-off information to the processor 6 at the sunrise time of each day, and sends light-on information to the processor 6 at the sunset time of each day. The processor 6 sends light-off and light-on instructions to the controller according to the light-off and light-on information sent by the timer, and the controller controls the switch of the street lamp to achieve the effect of turning off the light at sunrise and turning on the light at sunset. At the same time, the light sensor collects light intensity information of the environment around the street lamp and transmits the light intensity information to the processor. The processor compares the light intensity information with the light intensity threshold range preset in the processor. When the light intensity reaches the upper limit of the threshold, the processor controls the controller to cut off the power supply of the street lamp. When the light intensity is lower than the lower limit of the threshold, the processor controls the controller to connect the power supply of the street lamp. The switch of the street lamp is controlled according to the light intensity of the environment around the street lamp collected by the light sensor. In special weather conditions, the street lamp can be turned on in advance or turned off later due to dimming of the light. In characteristic weather such as cloudy days, dusty weather, etc., the purpose of automatically controlling the switch of the street lamp according to the intensity of the ambient light can be achieved.

[0030] Since there are fewer vehicles and pedestrians on the road at night, especially late at night, if the street lights are illuminated at a single brightness throughout the night, it will cause a waste of resources. The users of street lights on the road mainly include pedestrians and vehicles. Since the vehicles themselves have lights, this application mainly controls the brightness of street lights according to the situation of pedestrians on the road to achieve the purpose of energy saving. The pedestrian heat source sensing component includes an infrared human body sensor and a laser sensor. The infrared human body sensor is used to detect whether a pedestrian passes by, and the laser sensor is used to detect whether the pedestrian is within the lighting range of the street light. When the infrared human body sensor detects that a pedestrian passes by, the laser sensor detects the distance information between the pedestrian and the street light and transmits it to the processor 6. The processor 6 determines whether the pedestrian enters the lighting range of the street light according to the preset lighting range of the street light. When the pedestrian enters the lighting range of the street light, the processor 6 sends a street light brightness adjustment signal to the controller 5 to increase the brightness of the street light to meet the lighting needs of the pedestrian; on the contrary, when the processor determines that there is no pedestrian within the lighting range of the street light according to the information of the pedestrian heat source sensing component, the processor 6 sends a street light brightness adjustment signal to the controller 5 to reduce the brightness of the street light to ensure the necessary lighting for vehicles passing on the road.

[0031] The controller can be selected according to the type of street lamp. A controller that can achieve the switching and brightness adjustment of the street lamp can be selected from the general models, which will not be described in detail here.

It has fast processing speed, low power consumption, and strong stability, and is suitable for more complex street light control logic;

[0033] Infrared human body sensor is a sensor that uses the physical properties of infrared rays for detection. When pedestrians pass by, the infrared rays radiated by the human body can be detected by the infrared human body sensor. You can choose SZ89 / SAJ75-ABT series infrared detectors and select infrared detectors with different detection distances according to the setting distance of street lamps.
