[0065] In the city intelligent lighting system of the embodiment, the photovoltaic power supply performs photoelectric conversion, energy storage and discharge. When the first pulse signal output at the IO1 end of the first controller U1 turns on the first field effect transistor Q1, the energy released by the photovoltaic power supply is transmitted to the main lighting lamp through the first field effect transistor Q1. At the same time, the second pulse signal output at the IO2 end of the first controller U1 is transmitted to the first operational amplifier OP1 through the first thyristor S1. The sampled signal is adjusted by the third resistor R3 to adjust the conduction state of the second triode V2, thereby controlling the main lighting lamp to work in constant current lighting. At the same time, the first photoresistor RG1 detects the lighting state of the adjacent independent lighting lamp on the left side of the main lighting lamp, and when the adjacent independent lighting lamp on the left side of the main lighting lamp is dark and the first field effect transistor Q1 is turned on, a high level is output at the Y end of the first logic gate device U3 to trigger the second field effect transistor Q2 to be turned on, so that the photovoltaic energy of the adjacent independent lighting lamp on the left side of the main lighting lamp connected to the left side photovoltaic power supply interface is transmitted to the DC bus.

Similarly, the first trigger device detects the lighting state of the adjacent independent lighting lamp on the right side of the main lighting lamp. When the adjacent independent lighting lamp on the right side of the main lighting lamp is dark and the first field effect transistor Q1 is turned on, a high level is output to trigger the third field effect transistor Q3 to be turned on, so that the photovoltaic energy of the adjacent independent lighting lamp on the right side of the main lighting lamp connected to the right side photovoltaic power supply interface is transmitted to the DC bus. At the same time, the first gate switch U2 triggers the third operational amplifier OP3 to work, controls the fourth triode V4 to be turned on, and the right auxiliary lighting lamp illuminates in the direction of the adjacent independent lighting lamp on the right side of the main lighting lamp. The fourth operational amplifier OP4 cooperates with the ninth resistor R9, the tenth resistor R10, the eleventh resistor R11, the twelfth resistor R12, the second crystal diode D2, the third crystal diode D3 and the thirteenth resistor R13 to add the voltage of the signals output at the OUT1 end and the OUT2 end of the first gate switch U2. Then, when the left auxiliary lighting lamp illuminates or the right auxiliary lighting lamp illuminates, the first operational amplifier OP1 controls the first triode V1 to be turned on, thereby reducing the conduction angle of the first thyristor S1 and reducing the brightness of the main lighting lamp. If the left auxiliary lighting lamp illuminates and the right auxiliary lighting lamp also illuminates, the conduction angle of the first thyristor S1 will be further reduced, and the brightness of the main lighting lamp will be further reduced, thereby realizing energy-saving lighting control.

[0066] It will be obvious to a person skilled in the art that the application is not limited to the details of the foregoing exemplary embodiments and can be implemented in other concrete forms without departing from the spirit or essential characteristics of the application. The embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No reference signs in the claims should be considered as limiting the scope of the claims to the identity of the reference signs therein.

[0067] Furthermore, it should be understood that although the description is made on the basis of the embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.
