[0030] The light adaptive control component 9 includes a magnetic connector 901, a magnetic mount 902 is magnetically connected to the side end of the magnetic connector 901, an LED protective self-adjusting lamp 903 is installed on the side end of the magnetic mount 902, a waterproof cover 904 is installed on the side end of the magnetic mount 902, a semi-arc electromagnetic guide rail 905 is installed on the top of the inner part of the waterproof cover 904, a position sliding connection block 906 is slidably connected to the inner part of the semi-arc electromagnetic guide rail 905, a micro-electric guide rod 907 is fastened to the bottom of the position sliding connection block 906, and the micro-electric guide rod 907 is fastened to the bottom of the position sliding connection block 906. The bottom end of the rod 907 is fastened to the outer frame 908, the side end of the outer frame 908 is installed with a first angle control motor 909, the side end of the first angle control motor 909 is installed with an angle control sensor 9090, the output end of the first angle control motor 909 is connected to an inner rotating frame 9091, the bottom end of the inner rotating frame 9091 is rotatably connected to a position control sensor 9093, the bottom of the position control sensor 9093 is installed with a second angle control motor, and the top output end of the second angle control motor is connected to a prism frame 9092.

[0031] In a specific solution, the column 1 is first fixed at a suitable position in the courtyard to ensure that it is firmly installed, and then the slide seat 11 is connected to slide and adjust the top side of the column 1. When the courtyard light is powered on, the light sensor group 8 starts to work, detects information such as the light intensity of the surrounding environment, and transmits the data to the processing controller 2. When the processing controller 2 determines that the lighting orientation needs to be adjusted based on the data of the light sensor group 8, the orientation adaptive adjustment component 10 is started, and it uses the internal driving mechanism (such as a motor and a gear group or a rotating electromagnetic device) to make the light adaptive control component 9 rotate within a certain range, so that when the position of the sun changes or there are objects in the courtyard blocking the light and causing insufficient light in a local area, the orientation adaptive adjustment component 10 operates to change the irradiation direction of the light. During the operation, the orientation adjustment limiting component 5 monitors and limits the rotation range and angle to prevent the rod body from excessively rotating to cause damage to the lamp or affect the lighting effect of other areas. At the same time, the angle control sensor 9090 monitors the rotation angle of the first angle control motor 909 in real time, and feeds back the data to the processing controller 2 to accurately control the orientation adjustment of the rotation operation;

[0032] During operation, the light sensor group 8 continuously monitors the ambient light conditions. When changes in light intensity, light distribution, etc. are detected, the signal is transmitted to the processing controller 2, so that the processing controller 2 starts the light adaptive control component 9 to adjust the light angle and intensity according to these signals, so that the magnetic connector 901 and the magnetic mounting seat 902 ensure the stable installation of the LED protective self-adjusting lamp 903, and also facilitate the disassembly and maintenance of the lamp. After the semi-arc electromagnetic guide rail 905 is energized, the driving position sliding connection block 906 moves, thereby driving the micro electric guide rod 907 and the outer frame 908 to adjust their positions in the vertical direction, changing the LED protective self-adjusting lamp 903. Height, thereby affecting the lighting range and intensity, so that when it is necessary to expand the lighting range, the micro electric guide rod 907 is extended to raise the related structure connected to the bottom, and then the first angle control motor 909 is started to drive the inner rotating frame 9091 to rotate. Secondly, the position control sensor 9093 monitors the position information of the inner rotating frame 9091 in real time and feeds back to the processing controller 2. Then, the second angle control motor drives the prism frame 9092 to rotate according to the instructions of the processing controller 2, changes the angle of light passing through the prism, and further adjusts the illumination direction and intensity distribution of the light, thereby realizing all-round and precise adjustment of the lighting angle as a whole to meet the lighting needs of different areas and different scenes in the courtyard.

[0033] Embodiment 2: In the present invention, according to Figure 1 - Figure 3 , Figure 5 and Figure 6 As shown, the azimuth adjustment limiting assembly 5 includes a limiting gear 501, the center end of the limiting gear 501 is installed inside the cavity of the rod body through a connecting column shaft, the side end of the limiting gear 501 is connected to an electromagnetic blocker 502, the side end of the limiting gear 501 is meshingly connected with a tooth edge 504, the side end of the tooth edge 504 is fastened with an angle adjustment arc frame 503, electric self-locking structures are installed at both ends of the cavity of the rod body, the electric self-locking structure is used to insert and fix the angle adjustment arc frame 503 passing through the cavity of the rod body, the side top of the angle adjustment arc frame 503 is fastened with a connecting piece 18, and the connecting piece 18 is fastened to the top side end of the slotted sliding frame 7.

[0034] The azimuth adaptive adjustment component 10 includes a driving brushless motor 101, the output end of the driving brushless motor 101 is connected to a rotating gear 102, the side end of the rotating gear 102 is meshingly connected with a vertical tooth edge 103, the side of the vertical tooth edge 103 is integrally formed with an inner sliding member 104, the inner sliding member 104 is located inside the slotted sliding frame 7 through the vertical tooth edge 103 to form a sliding connection, and a plurality of light auxiliary lamps 105 are installed at the bottom end of the inner sliding member 104.

[0035] The side end of the rod body is rotatably connected to the slot frame via a bearing shaft, and the rotating gear 102 is installed inside the slot frame.

[0036] In a specific solution, when the garden light is installed and powered on for the first time, the angle adjustment bracket 503 can rotate freely within a certain range inside the cavity of the rod body. At this time, the electromagnetic blocker 502 does not apply a braking effect to the limiting gear 501. The limiting gear 501 can passively rotate with the rotation of the angle adjustment bracket 503. The processing controller 2 drives the azimuth adaptive adjustment component 10 to rotate the rod body to a roughly appropriate initial azimuth. During this process, the limiting gear 501 and the tooth edge 504 cooperate with each other to record the initial relative position information. When the initial azimuth calibration is completed, the electric self-locking structure is started to insert and fix the angle adjustment bracket 503 into the cavity of the rod body to limit its further free rotation. At the same time, the electromagnetic blocker 502 applies appropriate electromagnetic force to the limiting gear 501 according to the instructions of the processing controller 2, thereby generating a braking effect to prevent the limiting gear 501 from accidentally rotating due to external interference, thereby ensuring the azimuth stability of the rod body. During daily lighting, as long as no azimuth adjustment instruction is received from the controller, the azimuth adjustment limiting component 5 will always maintain this locked state to maintain the established lighting azimuth of the garden lamp. When the light sensor group 8 detects a change in ambient light and the azimuth needs to be adjusted, the controller first sends an unlocking signal to the electric self-locking structure to release the fixation of the angle adjustment arc bracket 503. At the same time, the electromagnetic blocker 502 reduces the braking electromagnetic force on the limiting gear 501, allowing the limiting gear 501 to rotate freely to a certain extent. The light sensor group 8 detects that the light intensity in different areas of the courtyard is unbalanced or the ambient light conditions have changed significantly (such as the movement of the sun's position, cloud cover, etc.), and transmits this information to the processing controller 2. The processing controller 2 determines that the orientation needs to be adjusted according to the preset algorithm and light balance requirements, and sends a corresponding drive instruction to the orientation adaptive adjustment component 10, driving the brushless motor 101 to start according to the instruction of the processing controller 2, output torque and drive the rotating gear 102 to rotate. The rotating gear 102 meshes with the vertical tooth edge 103, and transmits the rotational motion to the vertical tooth edge 103, so that it slides in the vertical direction inside the slotted sliding frame 7. Since the vertical tooth edge 103 is integrally formed with the inner sliding member 104, the inner sliding member 104 It also slides in the slotted sliding frame 7, and through the support of the bearing shaft, drives the light adaptive control component 9 to rotate around the bearing shaft to adjust the orientation. During the rotation process, the multiple groups of light auxiliary lamps 105 at the bottom of the inner sliding member 104 also move with the light adaptive control component 9, and their irradiation directions change synchronously. When the light adaptive control component 9 rotates to the ideal orientation calculated by the processing controller 2 according to the data of the light sensor group 8, the controller sends a stop command to the driving brushless motor 101, driving the brushless motor 101 to stop outputting torque, and the gear 102 stops rotating. The light adaptive control component 9 is stabilized in the new orientation. At this time, the orientation adjustment limiting component 5 starts the locking mechanism to fix the orientation of the light adaptive control component 9.To prevent it from being offset due to external interference and ensure that the garden lamp can continue to provide stable lighting services in the new orientation, the limiting gear 501 rotates accordingly with the rotation of the angle adjustment arc frame 503, and during the rotation process, the electromagnetic blocker 502 continuously monitors the rotation angle and speed of the limiting gear 501. When the light adaptive control component 9 rotates to a position that meets the new lighting requirements, the processing controller 2 sends a signal to the electric self-locking structure and the electromagnetic blocker 502 again, and the electric self-locking structure re-fixes the angle adjustment arc frame 503, and the electromagnetic blocker 502 strengthens the braking of the limiting gear 501, so that the light adaptive control component 9 is stable in the new orientation.

[0037] Embodiment 3: In the present invention, according to Figure 1 - Figure 4 As shown, a side sliding column 3 is integrally formed at the side end of the column 1, a vertical guide slot 13 is provided at the connecting end of the side sliding column 3 and the column 1, and a connecting slide seat 11 is located inside the guide slot 13 and the side sliding column 3 for sliding connection.

[0041] In a specific solution, when the garden light is initially installed or needs to be adjusted in height, the processing controller 2 first determines the target height position information of the connecting slide 11 according to a preset program or an external input instruction (such as a manual operation instruction), and the energy-saving motor 16 starts to work after receiving the start signal of the processing controller 2. The energy-saving motor 16 serves as a power source, and its output shaft is connected to the screw gear 17, driving the screw gear 17 to start rotating. The rotation of the screw gear 17 drives the screw 15 meshing therewith to rotate, and since the screw 15 is threadedly connected to the internal threaded sleeve column 14, and the top of the screw 15 is fastened to the connecting slide 11 Then, during the rotation of the screw rod 15, the connecting slide 11 will slide up and down along the path defined by the vertical guide slot 13 and the side slide column 3, or when necessary, the screw rod 15 can be rotated clockwise, and the connecting slide 11 will move upward under the action of the thread, and vice versa. During the movement of the connecting slide 11, the processing controller 2 will monitor the current position information of the connecting slide 11 in real time through the position positioning sensor installed at the side end of the connecting slide 11, and compare it with the target height position. When the connecting slide 11 approaches the target height position, the processing controller 2 will control the energy-saving motor 16 to decelerate according to the preset deceleration strategy. The low speed enables the connecting slide 11 to reach the target height position smoothly, avoiding position deviation due to inertia, and the overall convenience of modular replacement and adjustment of the LED protective self-adjusting lamp 903 according to the user's preferences. When the connecting slide 11 reaches the target height position, the processing controller 2 establishes an electrical connection with the light source adjustment circuit inside the inner slide 104 through the control circuit 6 to realize the control of the lighting system, wherein the processing controller 2 can realize the control of the lighting system according to different times (such as day, night, dusk, etc.), ambient light intensity (feedback through the light sensor group 8) and user-set scene modes (such as party mode, leisure mode mode, security mode, etc.), sends corresponding control signals to the light source adjustment circuit to adjust the brightness, color (if it is a color-changing LED lamp), switch state and other parameters of the light auxiliary lamp 105 at the bottom of the inner sliding part 104 and the LED protection self-adjusting lamp 903, so that in the leisure mode at night, the processing controller 2 can adjust the brightness of the light auxiliary lamp 105 to a moderate level, and make the LED protection self-adjusting lamp 903 illuminate the courtyard with soft warm white light. In the security mode, the LED protection self-adjusting lamp 903 and the light auxiliary lamp 105 may all be adjusted to the brightest state, and the lights may flash at a specific flashing frequency to serve as a warning.

During the rotation of the screw rod 15, the connecting slide 11 will slide up and down along the path defined by the vertical guide slot 13 and the side slide column 3, or when necessary, the screw rod 15 can be rotated clockwise, and the connecting slide 11 will move upward under the action of the thread. During the movement of the connecting slide 11, the processing controller 2 will monitor the current position information of the connecting slide 11 in real time through the position positioning sensor installed on the side end of the connecting slide 11, and compare it with the target height position. When the connecting slide 11 approaches the target height position, the processing controller 2 will control the energy-saving motor 16 to reduce the speed according to the preset deceleration strategy, so that the connecting slide 11 can smoothly reach the target height position to avoid position deviation due to inertia. After reaching the target height position, the processing controller 2 establishes an electrical connection with the light source adjustment circuit inside the inner sliding member 104 through the control circuit 6 to realize the control of the lighting system, wherein the processing controller 2 can send corresponding control signals to the light source adjustment circuit according to different times (such as daytime, nighttime, dusk, etc.), ambient light intensity (feedback through the light sensor group 8) and scene modes set by the user (such as party mode, leisure mode, security mode, etc.), and adjust the brightness, color (if it is a color-changing LED lamp), switch state and other parameters of the light auxiliary lamp 105 at the bottom of the inner sliding member 104 and the LED protective self-adjusting lamp 903, so that in the leisure mode at night, the processing controller 2 can adjust the brightness of the light auxiliary lamp 105 to a moderate level. The LED protective self-adjusting lamp 903 is leveled and illuminates the courtyard with soft warm white light. In the security mode, the LED protective self-adjusting lamp 903 and the light auxiliary lamp 105 may all be adjusted to the brightest state, and the light is flashed at a specific flashing frequency to serve as a warning. Then, the processing controller 2 drives the azimuth adaptive adjustment component 10 to rotate the rod body to a roughly suitable initial azimuth. During this process, the limiting gear 501 and the tooth edge 504 cooperate with each other to record the initial relative position information. When the initial azimuth calibration is completed, the electric self-locking structure is started to insert and fix the angle adjustment arc frame 503 into the cavity of the rod body to limit its further free rotation. At the same time, the electromagnetic blocker 502, according to the instruction of the processing controller 2,Appropriate electromagnetic force is applied to the limiting gear 501 to produce a braking effect, thereby preventing the limiting gear 501 from accidentally rotating due to external interference, thereby ensuring the azimuth stability of the rod body. During daily lighting, as long as no azimuth adjustment command is received from the controller, the azimuth adjustment limiting component 5 will always maintain this locked state to maintain the established lighting azimuth of the garden lamp. When the light sensor group 8 detects changes in ambient light and the orientation needs to be adjusted, the controller first sends an unlocking signal to the electric self-locking structure to release the fixation of the angle adjustment arc bracket 503. At the same time, the electromagnetic blocker 502 reduces the braking electromagnetic force on the limiting gear 501, allowing the limiting gear 501 to rotate freely to a certain extent. When the light sensor group 8 detects different ambient light conditions in the courtyard, the limiting gear 501 will rotate freely to a certain extent. When the light intensity in the area is unbalanced or the ambient light conditions change significantly (such as the movement of the sun's position, cloud cover, etc.), and this information is transmitted to the processing controller 2, the processing controller 2 determines that the orientation needs to be adjusted according to the preset algorithm and light balance requirements, and sends a corresponding drive instruction to the orientation adaptive adjustment component 10, driving the brushless motor 101 to start according to the instruction of the processing controller 2, output torque and drive the rotating gear 102 to rotate, and the rotating gear 102 meshes with the vertical tooth edge 103, and transmits the rotational motion to the vertical tooth edge 103, so that it slides in the vertical direction inside the slotted slide frame 7. Since the vertical tooth edge 103 and the inner sliding member 104 are integrally formed, the inner sliding member 104 also slides in the slotted slide frame 7, and And through the support of the bearing shaft, the light adaptive control component 9 is driven to rotate around the bearing shaft to achieve the adjustment of the orientation. During the rotation process, the multiple groups of light auxiliary lamps 105 at the bottom of the inner sliding member 104 also move with the light adaptive control component 9, and their irradiation directions change synchronously. When the light adaptive control component 9 rotates to the ideal orientation calculated by the processing controller 2 according to the data of the light sensor group 8, the controller sends a stop command to the driving brushless motor 101, driving the brushless motor 101 to stop outputting torque, the gear 102 stops rotating, and the light adaptive control component 9 stabilizes at the new orientation. At this time, the orientation adjustment limiting component 5 starts the locking mechanism to fix the orientation of the light adaptive control component 9 to prevent it from being offset due to external interference. , to ensure that the garden lamp can continue to provide stable lighting services in the new orientation, the limiting gear 501 rotates accordingly with the rotation of the angle adjustment arc frame 503, and during the rotation process, the electromagnetic blocker 502 continuously monitors the rotation angle and speed of the limiting gear 501. When the light adaptive control component 9 rotates to a position that meets the new lighting requirements, the processing controller 2 sends a signal to the electric self-locking structure and the electromagnetic blocker 502 again, and the electric self-locking structure re-fixes the angle adjustment arc frame 503. The electromagnetic blocker 502 strengthens the braking of the limiting gear 501, so that the light adaptive control component 9 is stable in the new orientation. After that, the light sensor group 8 continuously monitors the ambient light conditions. When changes in light intensity, light distribution, etc. are detected,The signal is transmitted to the processing controller 2, so that the processing controller 2 starts the light adaptive control component 9 to adjust the light angle and intensity according to these signals, so that the magnetic connector 901 and the magnetic mounting seat 902 ensure the stable installation of the LED protective self-adjusting lamp 903, and also facilitate the disassembly and maintenance of the lamp. After the semi-arc electromagnetic guide rail 905 is energized, the driving position sliding connection block 906 moves, thereby driving the micro-electric guide rod 907 and the outer frame 908 to adjust their positions in the vertical direction, changing the height of the LED protective self-adjusting lamp 903, thereby affecting the lighting range and intensity, which is convenient for expanding the lighting when it is necessary. When the lighting range is reached, the micro electric guide rod 907 extends to raise the related structure connected to the bottom end, and then the first angle control motor 909 is started to drive the inner rotating frame 9091 to rotate. Secondly, the position control sensor 9093 monitors the position information of the inner rotating frame 9091 in real time and feeds it back to the processing controller 2. Then, the second angle control motor drives the prism frame 9092 to rotate according to the instructions of the processing controller 2, changes the angle of light passing through the prism, and further adjusts the illumination direction and intensity distribution of the light, so as to achieve all-round and precise adjustment of the lighting angle as a whole, and meet the lighting needs of different areas and scenes in the courtyard.
