Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
please refer to fig. 1, fig. 1 is a schematic structural diagram of an intelligent lighting control system, which is applied to a planting box, and includes an adaptive power module 3 for outputting direct current, and further includes:
The output end of the induction module 1 is connected with the signal input end of the control module 2;

The sensing module 1 is specifically used for detecting whether a human body exists in a preset range (which can be 1m or 2m, certainly, also can be other numerical values, and is specifically determined according to actual conditions) of the planting box, and can output a first signal to the control module 2 when sensing the human body in the preset range of the planting box, and can output a second signal to the control module 2 when not sensing the human body in the preset range of the planting box. Preferably, the sensing module 1 can be, but is not limited to be, disposed on the planting box, so as to more conveniently measure whether people are around the planting box accurately and effectively.

The principle of the present embodiment mainly utilizes a voltage feedback loop (implemented by an operational amplifier a), specifically, the voltage output module 23 outputs a corresponding reference voltage to the operational amplifier a in the voltage feedback loop according to the sensing condition of the sensing module 1 to change the reference voltage set value of the operational amplifier a, the operational amplifier a compares the output voltage of the transformer circuit 22, that is, the input voltage of the lighting module, with the reference voltage set value, and controls the driving module 21 according to the comparison result, and further controls the transformer circuit 22 through the driving module 21 to change the amplitude of the output voltage of the transformer circuit 22, so that the output voltage of the transformer circuit 22 is finally equal to the reference voltage set value.
in a specific implementation, the reference voltage of the voltage output module 23 may be output to a non-inverting input terminal of the operational amplifier a (as shown in fig. 2), or may be output to an inverting input terminal of the operational amplifier a.
Specifically, when the output terminal of the voltage output module 23 is connected to the non-inverting input terminal of the operational amplifier a:
the voltage output module 23 is specifically configured to output a first reference voltage value to the operational amplifier a when the sensing module senses a human body within a preset range of the planting box, and output a second reference voltage value to the operational amplifier a when the sensing module does not sense a human body within the preset range, where the first reference voltage value is smaller than the second reference voltage value;
