[0091] This embodiment also discloses an intelligent indoor lighting adjustment method, which includes the following steps:

[0092] S1. When a student sits on the corresponding desk and chair 13, the human body detection sensor 131 on the desk and chair 13 will detect the student and generate a trigger signal. The generated trigger signal is transmitted to the main wireless module 623 through the sub-wireless module 132 on the desk and chair 13.

[0093] S2. Based on the trigger signal received by the mother wireless module 623, the main control chip 622 not only controls the multi-axis displacement component to drive the installation film 40 to move, but also adjusts the brightness of the lighting component through the PWM dimming circuit 625;

[0094] S3. If the mother wireless module 623 only receives one trigger signal, the main control chip 622 controls the multi-axis displacement component to drive the installation film 40 to move to the top of the corresponding desks and chairs 13; if the mother wireless module 623 only receives multiple trigger signals, the main control chip 622 controls the multi-axis displacement component to drive the installation film 40 to move to the central position of the corresponding multiple desks and chairs 13.

[0095] The working principle of this embodiment is:

[0096] 1. The initial level of the human body detection sensor 131 is a low level; when a student sits on the corresponding desk and chair 13, the human body detection sensor 131 on the desk and chair 13 will detect it and generate a high level trigger signal, and the generated trigger signal is transmitted to the mother wireless module 623 through the sub-wireless module 132 on the desk and chair 13; the mother wireless module 623 feeds back the received trigger signals to the main control chip 622; based on the trigger signal received by the mother wireless module 623, the main control chip 622 will not only control the multi-axis displacement component to drive the lighting component to move, but also adjust the brightness of the lighting component through the PWM dimming circuit 625.

[0097] Specifically, if the mother wireless module 623 receives only one trigger signal, the main control chip 622 controls the multi-axis displacement component to drive the lighting component to move to the top of the corresponding desk and chair 13. Since there is only one student, the brightness of the lighting component is adjusted to the lowest brightness through the PWM dimming circuit 625, which only ensures that the student can see the content on the desk and chair 13, effectively reducing energy consumption. If the mother wireless module 623 receives only multiple trigger signals, the main control chip 622 controls the multi-axis displacement component to drive the lighting component to move to the central position of the corresponding multiple desks and chairs 13, and adjusts the brightness of the lighting component to a medium and appropriate brightness through the PWM dimming circuit 625 to ensure that each student can see the content on the desk and chair 13, and the energy consumption is reduced compared to full brightness. If there are students on each desk and chair 13, the lighting component moves to the center of the classroom, and the brightness of the lighting component is adjusted to the highest brightness through the PWM dimming circuit 625. At this time, all students can see the content on the desk and chair 13.

[0098] It should be noted that the main control chip 622 is connected to an external PLC (or single chip microcomputer or PC) through the mother wireless module 623 , and the PLC controls the first drive motor 162 , the second drive motor 27 and the third drive motor 35 .

[0099] 2. The main rod 12 serves as a carrier for forward and backward movement, and can move forward and backward based on the transmission of the first rack 15 and the first gear, and the first drive motor 162 provides rotational force for the first gear; the main displacement seat 22 serves as a carrier for left and right movement, and can move left and right based on the transmission of the second rack 26 and the second gear 28, and the second drive motor 27 provides rotational force for the second gear 28; the auxiliary rod 31 serves as a carrier for up and down movement, and can move up and down based on the transmission of the third rack 34 and the third gear 36, and the third drive motor 35 provides rotational force for the third gear 36; the lighting assembly is fixed on the mounting seat 41 to realize three-axis position movement.

[0100] 3.1. Before installing the control circuit board 61, a handheld miniature electric-controlled air pump is needed. The electric-controlled air pump is aligned with the inlet end of the control valve 87 and turned on. The air generated by the electric-controlled air pump can be brought into the absorption cavity 843 through the outlet end of the control valve 87 and the connecting channel 88, thereby making the absorption cavity 843 continuously expand, the main moving block 832 moves upward and drives the downward pressure top block 82 to move upward, and the downward pressure top block 82 can eventually move upward and shrink in the downward pressure channel 81 to avoid hindering the control circuit board 61 from being pushed into the side installation groove; then, the control valve 87 is closed by the hand wheel 871 to prevent the air in the absorption cavity 843 from leaking;

[0101] 3.2.1. When installing the control circuit board 61, push the control circuit board 61 into the side push-in slot 71. The right end of the control circuit board 61 will squeeze the forward displacement surface 896 of the upper spring block 892, and after continuously pushing down the upper spring block 892, it will be stably and smoothly pushed into the side push-in slot 71. When the control circuit board 61 is pushed in until it hits the bottom of the side push-in slot 71, the positions of the first electrical pin 731 and the first electrical socket 611 match.

[0102] 3.2.1. Open the control valve 87, and the air in the inner cavity 843 is discharged from the inlet end of the control valve 87; at this time, the downward pressure of the downward pressure spring 85 can press the control circuit board 61 downward to make it move downward, so that the first electrical pin 731 is inserted downward into the first electrical socket 611 to form an electrical connection; the control circuit board 61 collides with the upper spring seat 891 to limit the position, and the positioning column 612 collides with the lower end surface of the side push-in groove 71 to limit the position, thereby maintaining the stability of the control circuit board 61.

[0103] 3.3. When removing the control circuit board 61, align the electric control air pump with the inlet end of the control valve 87, turn on the electric control air pump, and after the air is brought into the absorption cavity 843, the downward pressure block 82 will move up and shrink in the downward pressure channel 81; the upward force of the upward spring 893 will be smaller than the downward force of the downward pressure spring 85. When the downward pressure block 82 moves up and shrinks in the downward pressure channel 81, the upward spring block 892 can realize the upward spring of the control circuit board 61, thereby separating the first electrical pin 731 and the first electrical socket 611, so as to facilitate pulling out the control circuit board 61; the problem that the control circuit board 61 cannot be pulled up by hand is solved.

[0104] 4.1. The lighting circuit board 52 is fixed at the bottom of the lighting housing 51. When installing the lighting housing 51, the two limit blocks 91 at the upper end of the lighting housing 51 can be pushed upward into the lower push-in groove 92, and an electrical connection is formed by plugging the second electrical pin 931 and the second electrical socket 932. In the process of pushing up the two limit blocks 91, the avoidance surface 962 on the outer side of the press-in block 96 can be squeezed and automatically retracted during the upward movement of the limit block 91, thereby optimizing smoothness. Finally, the two press-in blocks 96 can be pressed into the corresponding press-in grooves 911 respectively, thereby realizing the limiting and locking of the lighting housing 51.

[0105] 4.2. When it is necessary to maintain or replace the LED lamp 53 on the lighting circuit board 52, the lighting housing 51 needs to be disassembled; when disassembling the lighting housing 51, a handheld miniature electrically-controlled air pump needs to be used, and the electrically-controlled air pump needs to be aligned with the connecting inner tube 991, and the electrically-controlled air pump is turned on. The air generated by the electrically-controlled air pump can be brought into the two notched areas 974 after passing through the second inner channel 992 and the first inner channel 98, and the two driving blocks 971 will be forced to move inward, and the two pressing blocks 96 will move inward synchronously, and then respectively disengage from the corresponding pressing grooves 911; at this time, the lighting housing 51 can fall smoothly under its own gravity, and the operator only needs to catch the falling lighting housing 51.

[0106] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
