[0064] To enable those skilled in the art to better understand this solution, the technical solutions in the embodiments of this solution will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this solution, not all of them. Based on the embodiments of this solution, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this solution.

[0065] The term "comprising" and any other variations thereof in the specification, claims, and accompanying drawings of this invention mean "including but not limited to," and are intended to cover a non-exclusive inclusion, not limited to the examples listed herein. Furthermore, the terms "first" and "second," etc., are used to distinguish different objects, not to describe a specific order.

[0066] The implementation of this disclosure will be described in detail below with reference to the specific accompanying drawings:

[0067] Figure 1 This is a schematic diagram of the structure of an intelligent city lighting system provided in an embodiment of this disclosure. (Refer to...) Figure 1 The smart city lighting system includes:

[0068] The system includes a rectifier and filter module 10, a light intensity detection module 11, a light sensor control module 12, a switch module 13, a pyroelectric detection module 14, a boost module 15, and an LED module 16.

[0069] The input terminal of the rectifier and filter module 10 is used to connect to the mains power, the output terminal of the rectifier and filter module 10 is connected to the input terminal of the light intensity detection module 11, and the output terminal of the light intensity detection module 11 is connected to the input terminal of the light sensing control module 12.

[0070] The input terminal of the light-sensing control module 12 is connected to the output terminal of the rectifier and filter module 10, the output terminal of the light-sensing control module 12 is connected to the first terminal of the switch module 13, and the second terminal of the switch module 13 is connected to the LED module 16.

[0071] The input terminal of the pyroelectric detection module 14 is connected to the output terminal of the light sensing control module 12, the output terminal of the pyroelectric detection module 14 is connected to the control terminal of the switch module 13, the third terminal of the switch module 13 is connected to the input terminal of the boost module 15, and the output terminal of the boost module 15 is connected to the LED module 16.

[0072] In this embodiment, the boost module 15 enables the system to adapt to different voltage inputs, ensuring that the LED module 16 operates stably and efficiently even in complex power grid environments. The rectifier and filter module 10 processes the mains power, providing stable and clean DC power to the entire system. This disclosure utilizes the cooperation of the light intensity detection module 11 and the light-sensing control module 12 to automatically turn the lighting on or off based on the intensity of ambient light. During the day when there is sufficient light, the LED module 16 is automatically turned off; while at night when the light is dim, the LED module 16 is automatically turned on, and the LED module 16 is in its initial low-power state. This method avoids lighting redundancy and greatly reduces unnecessary energy consumption.

[0073] The light-sensing control module 12 of this disclosure supplies power to the pyroelectric detection module 14. When the pyroelectric detection module 14 detects someone approaching at night, it outputs a high-level signal, causing the path of the switching module 13 to switch to the boost module 15. The voltage output by the light-sensing control module 12 passes through the boost module 15. The boost module 15 increases the voltage of the LED module 16 to increase the light intensity of the LED module 16 and provide sufficient lighting for people. In unoccupied areas, the LED module 16 will automatically maintain its initial low-power state, thereby effectively saving energy.

[0074] This disclosure combines light intensity detection and human presence detection to dynamically adjust lighting strategies.

[0075] Precise lighting control reduces energy waste, thereby lowering carbon emissions. This aligns with the modern urban concept of green and low-carbon development and optimizes resource utilization.

[0076] Figure 2 This is a schematic diagram of the structure of the second intelligent city lighting system provided in this disclosure embodiment, with reference to... Figure 2 ,

[0077] In one exemplary embodiment of this disclosure, the mains power can be considered as AC power supply U1. After processing by a transformer and rectifier bridge IC1, DC power is output. AC power supply U5 is connected to the input terminal of rectifier bridge IC1. The power output from the output terminal of rectifier bridge IC1 is filtered by capacitor C1, generating a voltage across capacitor C1 to power subsequent circuits. Additionally, the output terminal of rectifier bridge IC1 also provides power to LED D1, causing LED D1 to illuminate as a working indicator. If the operation is normal, LED D1 is lit, and the cathode of photodiode D2 (LED D2 should have an opaque protective casing to prevent interference from external light intensity) is energized.

[0078] In one exemplary embodiment of this disclosure, the light intensity detection module 11 includes: a sliding resistor R2, a resistor R3, and a photodiode D2;

[0079] The cathode of photodiode D2 is connected to the output terminal of rectifier filter module 10, and the anode of photodiode D2 is connected to the first terminal of sliding resistor R2.

[0080] The second end of the sliding resistor R2 is connected to the first end of the resistor R3, and the second end of the resistor R3 is grounded.

[0081] The third terminal of the sliding resistor R2 is connected to the input terminal of the light-sensing control module 12.

[0082] The light sensing control module 12 includes: a first time base chip IC2, a sliding resistor R6, a capacitor C2, a transistor V1, and a transistor V2;

[0083] The ground terminal of the first timer chip IC2 is grounded;

[0084] The low trigger terminal of the first time base chip IC2 is connected to the high trigger terminal of the first time base chip IC2;

[0085] The reset terminal of the first time base chip IC2 is connected to the power supply terminal of the first time base chip IC2;

[0086] The high trigger terminal of the first time base chip IC2 is connected to the output terminal of the light intensity detection module 11 and the first terminal of capacitor C2, respectively; the second terminal of capacitor C2 is grounded.

[0087] The power supply terminal of the first time base chip IC2 is connected to the output terminal of the rectifier and filter module 10;

[0088] The control voltage terminal of the first timer chip IC2 is grounded through the sliding resistor R6;

[0089] The output of the first timer chip IC2 is connected to the base of transistor V1;

[0090] The collector of transistor V1 is connected to the base of transistor V2, and the emitter of transistor V1 is grounded.

[0091] The emitter of transistor V2 is connected to the reset terminal of timer chip IC2, and the collector of transistor V2 is connected to the first terminal of switch module 13.

[0092] When the natural light intensity decreases, the internal resistance of the photodiode D2 gradually increases. After the voltage is divided by the sliding resistor R2 and the resistor R3, the voltage applied to the high trigger terminal of the first timer chip IC2 decreases. This causes the light-sensing control module to output a high level, which saturates and turns on the transistors V1 and V2, thus lighting up the LED module 16 through the switching module.

[0093] As the indoor natural light intensity gradually increases, the internal resistance of the photodiode D2 gradually decreases. After the voltage is divided by the sliding resistor R2 and the resistor R3, the voltage applied to the high trigger terminal of the first time base chip IC2 decreases, causing the light-sensing control module to stop working and the light to turn off automatically.

[0094] This disclosure utilizes the cooperation of a light intensity detection module 11 and a light sensing control module 12 to automatically turn the LED module 16 on or off according to the intensity of ambient light. When there is sufficient light during the day, the LED module 16 is automatically turned off; while at night when the light is dim, the LED module 16 is automatically turned on, and the LED module 16 is initially in a low-power state. This method avoids redundancy in lighting and greatly reduces unnecessary energy consumption.

[0095] In one exemplary embodiment of this disclosure, the pyroelectric detection module 14 includes: an infrared sensor IC3, a sliding resistor R9, a resistor R10, a resistor R11, a capacitor C3, a first amplifier L1, and a second amplifier L2.

[0096] The power supply terminal of the infrared sensor IC3 is connected to the output terminal of the light-sensing control module 12. The ground terminal of the infrared sensor IC3 is grounded. The output terminal of the first amplifier L1 is connected to the inverting input terminal of the first amplifier L1 through the sliding resistor R9. The output terminal of the first amplifier L1 is connected to the first terminal of the resistor R10, and the second terminal of the resistor R10 is connected to the inverting input terminal of the second amplifier L2.

[0097] The non-inverting input of the second amplifier L2 is connected to the first reference voltage VM1;

[0098] The output terminal of the second amplifier L2 is connected to the first terminal of the resistor R10 through the resistor R11, and the output terminal of the second amplifier L2 is connected to the control terminal of the switch module 13.

[0099] In one exemplary embodiment of this disclosure, the switching module 13 includes a relay K, a transistor V3, and a transistor V4;

[0100] The base of transistor V3 is connected to the output terminal of pyroelectric detection module 14; the emitter of transistor V3 is grounded, and the collector of transistor V3 is connected to the base of transistor V4.

[0101] The collector of transistor V4 is connected to the first power supply terminal of relay K;

[0102] The emitter of transistor V4 is connected to the output terminal of the light-sensing control module 12;

[0103] The second power supply terminal of relay K is grounded;

[0104] The first terminal of relay K is connected to the output terminal of light-sensing control module 12;

[0105] The second terminal of relay K is connected to LED module 16;

[0106] The third terminal of relay K is connected to the input terminal of boost module 15.

[0107] In one exemplary embodiment of this disclosure, the boost module 15 includes: a second time base chip IC4, resistors R13 and R14, capacitors C6, C7, C8, and C9, and diodes D3 and D4.

[0108] The reset terminal of the second time base chip IC4 is connected to the power supply terminal of the second time base chip IC4;

[0109] The power supply terminal of the second time base chip IC4 is connected to the third terminal of the switch module 13;

[0110] The ground terminal of the second time base chip IC4 is grounded;

[0111] The low trigger terminal of the second time base chip IC4 is connected to the high trigger terminal of the second time base chip IC4;

[0112] The high trigger terminal of the second time base chip IC4 is grounded through capacitor C6;

[0113] The high trigger terminal of the second time base chip IC4 is connected to the first terminal of resistor R13;

[0114] The second terminal of resistor R13 is connected to the third terminal of the switch module through resistor R14;

[0115] The discharge terminal of the second time base chip IC4 is connected to the second terminal of resistor R13;

[0116] The power supply terminal of the second timer chip IC4 is connected to the anode of diode D3;

[0117] The output of the second time base chip IC4 is connected to the anode of the diode D4 through capacitor C8;

[0118] The control voltage terminal of the second time base chip IC4 is grounded through capacitor C7;

[0119] The cathode of diode D3 is connected to the anode of diode D4;

[0120] The cathode of diode D4 is connected to the second output terminal of switch module 13.

[0121] When the natural light intensity decreases, the internal resistance of the photodiode D2 gradually increases. After the voltage is divided by the sliding resistor R2 and the resistor R3, the voltage applied to the high trigger terminal of the first time base chip IC2 decreases, causing the light sensing control module 12 to work. The light sensing control module 12 outputs a high level, causing the transistors V1 and V2 to saturate and conduct, and lighting up the LED module 16 through the switching module.

[0122] At this time, infrared sensor IC3 detects whether anyone is passing by. When someone is detected walking within the detection range of infrared sensor IC3, the weak infrared radiation emitted by the human body generates a voltage signal, which is output from the output terminal of infrared sensor IC3. This voltage signal is relatively weak, and it is amplified in two stages by the first amplifier L1 and the second amplifier L2. If the first amplifier L1 is used to amplify the voltage signal, the error should be as large as possible. By using the first amplifier L1 and the second amplifier L2 to amplify the voltage signal, a more accurate voltage signal is obtained. The voltage signal is output to the control terminal of switch module 13, causing transistors V3 and V4 of switch module 13 to saturate and conduct. At the same time, the collector voltage of transistor V4 is fed back to the base of transistor V3 through resistor R12, so that transistors V3 and V4 remain in the conducting state, ensuring that relay K is energized and self-holding. This causes the switch module to connect the boost module 15, which boosts the voltage output from the light-sensing control module and outputs it to LED module 16 to increase the light intensity of LED module 16.

[0123] In this invention, when someone approaches at night, the pyroelectric detection module 14 emits a high-level signal, and the switching module 13 automatically engages the coil. This causes the voltage output from the light-sensing control module 12 to pass through the boost module 15. The boost module 15 increases the voltage of the LED module 16 to enhance the light intensity and provide sufficient illumination for people. In unoccupied areas, the LED module 16 automatically maintains its initial low-power state, thereby effectively saving energy. Through precise lighting control, energy waste is reduced, thus lowering carbon emissions, which aligns with the modern urban green and low-carbon development concept and achieves optimized resource utilization.

[0125] The input terminal of the comparison module 17 is connected to the output terminal of the pyroelectric detection module 14;

[0126] The output of the comparator module 17 is connected to the control terminal of the switch module 13;

[0127] Comparison module 17 includes: comparator L3

[0129] The non-inverting input of comparator L3 is connected to the second reference voltage VM2;

[0131] In this embodiment, the inverting input of comparator L3 is connected to the output of pyroelectric detection module 14, and the non-inverting input of comparator L3 is connected to the second reference voltage VM2. Comparator L3 ensures that when someone is detected walking within the warning range of infrared sensor IC3, the boost module 15 will not immediately stop working after leaving the range, thus ensuring people's needs for light intensity.
