[0003] In the process of realizing this invention, the inventors discovered that the prior art has at least the following drawbacks:

[0004] (1) The solar panel and lighting components are set up separately, and the power is transmitted between them through cables. This design is costly, the messy cables are not easy to install and affect the aesthetics.

[0005] (2) The solar panel is fixed and cannot be automatically adjusted to the appropriate angle according to the intensity of light, resulting in less electrical energy generated, which means that the lighting components are not charged enough to support long-term lighting.

[0006] (3) The lighting components are fixed and cannot be adjusted according to the user's lighting needs, resulting in low flexibility of use.

[0007] In summary, how to solve any of the shortcomings of existing solar lighting devices is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0017] A driver, connected to the side wall of the housing, is used to drive the solar panel and the lamp panel to rotate around the rotation axis of the housing;

[0018] The control system is signal-connected to the driver, the voltage detection element, and the first electronic control element.

[0019] Preferably, the solar lighting device further includes a human body sensor, which is disposed on the circuit board and connected to the control system signal;

[0020] The circuit board is also provided with a second battery discharge circuit. The human body sensor is electrically connected to the battery through the second battery discharge circuit, and a second electronic control element is provided on the second battery discharge circuit.

[0021] Preferably, the probe of the human body sensor extends to the bottom end of the housing.

[0022] Preferably, the solar lighting device further includes a diffuser plate, which is disposed at the bottom end of the housing and has a limiting hole, into which the probe is inserted.

[0023] Preferably, the solar lighting device further includes a reflector cup, and the interior of the housing is provided with a support plate adjacent to the diffuser plate. The support plate has a through hole for the probe to pass through, and the support plate also has a light guide hole.

[0024] The second end of the reflector is located on the support plate and communicates with the light guide hole. The first end of the reflector is fitted into the lamp plate. Along the direction from the first end to the second end of the reflector, the cross-sectional area of ​​the reflector gradually increases.

[0025] Preferably, the bracket has a U-shaped structure, the driver is located on the right inner wall of the housing, the rotation shaft of the driver passes through the right side wall of the housing and is rotatably connected to the first side wall of the bracket, and the second side wall of the bracket is rotatably connected to the left side wall of the housing.

[0026] Preferably, the left side wall of the housing is provided with a guide rod, and the second side wall of the bracket is provided with a fan-shaped guide groove, and the guide rod can be slidably inserted into the fan-shaped guide groove;

[0027] Furthermore, the central angle of the fan-shaped guide groove is 90 degrees. When the guide rod is located in the middle position of the fan-shaped guide groove, the vertical line between the top and bottom of the box body is perpendicular to the side wall of the bracket and does not intersect.

[0028] Preferably, the solar lighting device further includes a first buckle and a second buckle. The first buckle is detachably disposed on the bottom wall of the bracket, and the second buckle is used for detachable installation on the ground or wall and is adapted to engage with the first buckle.

[0029] Preferably, the first buckle and the second buckle have the same structure, both including a U-shaped plate and an insert plate, and the insert plate is connected to one side of the top wall of the U-shaped plate along the width direction;

[0030] The bottom walls on both sides of the zigzag plate in the first buckle are detachably connected to the bottom wall of the bracket, and the bottom walls on both sides of the zigzag plate in the second buckle are detachably connected to the ground or a wall;

[0033] The solar lighting device provided by this utility model has a bracket that can be installed on the ground or a wall. During the day, the control driver rotates the top of the housing outward, and the solar panel absorbs sunlight and converts it into electrical energy. The electrical energy is stored in the battery through the battery charging circuit. During this period, the voltage detection element detects the voltage of the battery charging circuit and transmits it to the control system. This voltage value is the voltage of the solar panel, which can indirectly reflect the intensity of the light. Therefore, the control system can control the driver to rotate the solar panel to a suitable angle based on the obtained solar panel voltage value, so that the solar panel can obtain stronger light, thereby increasing the charging amount and increasing the lighting time of the lamp panel.

[0034] Additionally, when the solar panel voltage is below the preset minimum voltage threshold, it indicates extremely low light intensity or no light, signifying that it is evening or night. In this case, the driver rotates the enclosure so the bottom faces outwards, and the first electronic control element is activated. The battery transfers stored energy to the lamp panel through the first battery discharge circuit, causing the lamp panel to light up and the beam of light to be emitted through the bottom of the enclosure, providing illumination. It should be noted that users can control the enclosure rotation via the driver to adjust the lamp panel's illumination angle, thus meeting different lighting needs.

[0035] Therefore, the solar lighting device provided by this utility model has the following beneficial effects:

[0036] (1) The solar panel and the lamp panel are assembled on the box back to back, and the two are connected by a circuit board to transmit power. During the day, the solar panel faces outward to absorb sunlight, and at night the lamp panel faces outward to provide illumination. This design makes the lighting device compact, eliminates the need for cables to connect the solar panel and the lamp panel, makes it easy to install, saves costs, and has an attractive appearance.

[0037] (2) The solar panel can automatically adjust to the appropriate angle to obtain stronger light, thereby increasing the charging capacity and increasing the lighting time of the lamp panel.

[0038] (3) The light panel can adjust the direction of light according to the user's lighting needs, making it highly flexible in use. Attached Figure Description

Detailed Implementation

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] The core of this utility model is to provide a solar lighting device that is easy to install, cost-effective, aesthetically pleasing, provides long lighting time, and is highly flexible in use.

[0050] It should be noted that in this embodiment, the orientations or positional relationships indicated by terms such as "up," "down," "left," and "right" are based on the orientations or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, "first," "second," "third," "fourth," and "fifth" are used only to describe advantages and should not be construed as indicating or implying relative importance.

[0051] Please refer to Figure 1This application provides a solar lighting device, including a bracket 1, a housing 2, a solar panel 3, a circuit board, a battery, a lamp panel, a driver 5, and a control system. The bracket 1 is used for installation on the ground or a wall; the side wall of the housing 2 is rotatably connected to the bracket 1, and both the top and bottom of the housing 2 are open structures; the solar panel 3 is located at the top of the housing 2; the circuit board is located on the end face of the solar panel 3 facing the interior of the housing 2, and the circuit board includes a battery charging circuit and a first battery discharging circuit; the battery is located on the circuit board and electrically connected to the solar panel 3 through the battery charging circuit, which includes a voltage detection element; the lamp panel is located on the circuit board and illuminates the bottom of the housing 2, and the lamp panel is electrically connected to the battery through the first battery discharging circuit, which includes a first electronic control element; the driver 5 is connected to the side wall of the housing 2 and is used to drive the solar panel 3 and the lamp panel to rotate around the rotation axis of the housing 2; the control system is signal-connected to the driver 5, the voltage detection element, and the first electronic control element.

[0052] It should be noted that the box 2 is a three-dimensional structure, typically having a top, a bottom, and four side walls. In this application, the side walls of the box 2 can be rotatably connected to the bracket 1 via connectors (e.g., a pivot), allowing the box 2 to be rotatably mounted on the bracket 1 around a rotation axis (i.e., the axis of the pivot).

[0053] Please refer to Figure 1 and Figure 2 The rotating shaft 51 of the driver 5 is connected to the side wall of the housing 2. The rotating shaft 51 is parallel to the aforementioned rotation axis, causing the housing 2 to rotate around the rotation axis. This, in turn, causes the solar panel 3 and the lamp panel to rotate around the rotation axis of the housing 2, achieving alternating rotation so that the top and bottom of the housing 2 face outwards (e.g., relative to the wall). Furthermore, the top of the housing 2 is designed as an opening for the solar panel 3, and the bottom of the housing 2 is also designed as an opening to allow the light beam from the lamp panel to pass through and illuminate the surface. This allows the solar panel 3 to face outwards to absorb sunlight during the day and the lamp panel to face outwards to illuminate the surface at night. Optionally, the driver 5 can be a stepper motor. Stepper motors can achieve high-precision position and rotation speed control, thereby better controlling the rotation of the housing 2 to a suitable angle, and thus achieving precise control of the tilt angle of the solar panel 3 and the lamp panel.

[0054] Please refer to Figure 1 and Figure 2 The solar panel 3 is positioned at the top of the housing 2, with its front facing outwards to absorb sunlight and convert it into electricity. The back of the solar panel 3 faces inwards and connects to the interior of the housing 2, allowing a circuit board located inside the housing 2 to be mounted on the back of the solar panel 3. Understandably, the circuit board serves as a carrier for electronic components, connecting various components through wiring on its surface to achieve signal or power transmission.

[0055] Therefore, in this application, the battery and the lamp panel are integrated on a circuit board, and the circuit board is provided with a battery charging circuit and a first battery discharging circuit. The solar panel 3 is electrically connected to the battery through the battery charging circuit to store electrical energy in the battery. The battery is electrically connected to the lamp panel through the first battery discharging circuit to transfer the stored electrical energy to the lamp panel, that is, to supply power to the lamp panel to realize the illumination of the lamp panel. Among them, the battery charging circuit is provided with a voltage detection element (such as a voltmeter or potentiometer) to detect the voltage of the battery charging circuit, thereby reflecting the voltage of the solar panel 3; the first battery discharging circuit is provided with a first electronic control element, which is a circuit switch, used to control the circuit on and off.

[0056] In one specific embodiment, the light panel has multiple LEDs 4 arranged in an array to provide a wider and brighter illumination of the area where the device is located, such as... Figure 1 As shown.

[0057] It should be noted that the voltage of the solar panel can indirectly reflect the intensity of sunlight. Therefore, the control system signal is connected to the voltage detection element. The voltage detection element collects the voltage of the solar panel 3 through multiple detections and transmits the collected voltage values ​​to the control system. The control system uses the median average filtering method and the filtering algorithm for continuous judgment of voltage values ​​to remove voltage fluctuations and signal interference, so as to ensure the accuracy of the voltage detection value of the solar panel 3.

[0058] Furthermore, the control system processes the voltage threshold detected by the solar panel 3 using an adaptive threshold algorithm. This means the control system inputs a minimum voltage threshold; if the detected solar panel voltage is lower than this threshold, it indicates extremely low light intensity or no light, suggesting it is evening or night. This avoids detection errors during the day and night, ensuring the device's operational stability. Moreover, the control system can also input several voltage thresholds, each corresponding to a solar panel angle, to enable the solar panel 3 to track light intensity and maintain perpendicularity to the sunlight.

[0059] Therefore, when using the aforementioned solar lighting device, the bracket 1 can be installed on the ground or a wall, such as... Figure 4As shown, during the day, the control driver 5 rotates the top of the housing 2 outwards, and the solar panel 3 absorbs sunlight and converts it into electrical energy. The electrical energy is stored in the battery through the battery charging circuit. During this period, the voltage detection element detects the voltage of the battery charging circuit. This voltage value is the voltage of the solar panel 3 and is transmitted to the control system. The control system can use the median average filtering method and the continuous voltage value filtering algorithm to process and calculate the voltage value of the solar panel 3. Then, based on the calculated voltage value of the solar panel 3, the control driver 5 is used to rotate the solar panel 3 to a suitable angle so that the solar panel 3 is perpendicular to the sunlight, ensuring that the solar panel 3 receives stronger sunlight, thereby increasing the charging amount and increasing the lighting time of the lamp panel.

[0060] When the voltage value of solar panel 3 is lower than the preset minimum voltage threshold, it indicates that it is evening or night. Figure 5 As shown, the control driver 5 rotates the bottom of the housing 2 outwards and controls the first electronic control element to turn on. The battery transmits the stored electrical energy to the lamp board through the first battery discharge circuit. The lamp board lights up and the beam of light is emitted through the bottom of the housing 2 to provide illumination.

[0061] Based on the above embodiments, as a further preferred option, please refer to... Figure 1 and Figure 3 The solar lighting device also includes a human body sensor 6, which is mounted on a circuit board and connected to the control system signal. The circuit board also has a second battery discharge circuit, through which the human body sensor 6 is electrically connected to the battery. The second battery discharge circuit has a second electronic control element, which is a circuit switch used to control the circuit's on / off state.

[0062] It should be noted that the human body has a temperature and can emit infrared rays of a specific wavelength. The human body sensor 6 has a built-in infrared detector that can detect the infrared signals emitted by the human body. Thus, in this application, the human body sensor 6 is installed on the circuit board. The human body sensor 6 is electrically connected to the battery through the second battery discharge circuit on the circuit board, so that the human body sensor 6 is powered on. Since the bottom of the housing 2 is an open structure, at night, if a human body enters within the detection distance L of the human body sensor 6, the infrared detector will receive the infrared signal emitted by the human body and generate an electric charge through the pyroelectric effect. This charge is detected by the subsequent circuit and converted into an electrical signal, which is then transmitted to the control system.

[0063] The specific method for the control system to link the human body sensor 6 and the first electronic control element is as follows: When the voltage of the solar panel 3 is lower than the preset minimum voltage threshold, i.e., at night, the control system first activates the second electronic control element, energizing the human body sensor 6. If an electrical signal is detected from the human body sensor 6, it indicates that a pedestrian has passed by. Then, the control system activates the first electronic control element, energizing the first battery discharge circuit, and the light panel illuminates to provide lighting. Figure 5 As shown, if no electrical signal is received from the human body sensor 6, it indicates that no pedestrian has passed or that a pedestrian has already passed through the illuminated area. Then, the control system shuts down the first electronic control element, the first battery discharge circuit is de-energized, and the lamp panel goes out with no illumination. Figure 6 As shown.

[0064] Therefore, the aforementioned human body sensor 6 is used to control the switch of the light panel by detecting whether pedestrians are passing through. Specifically, when pedestrians are detected passing through the area, the light panel is turned on to illuminate, and when no pedestrians are detected passing through the area, the light panel is automatically turned off. This avoids wasting electricity due to prolonged lighting of the light panel, thereby saving the lighting time of the light panel and making the lighting time of the light panel longer.

[0065] Based on the above embodiments, as a further preferred option, please refer to... Figure 3 The probe 61 of the human body sensor 6 extends to the bottom of the housing 2.

[0066] Understandably, the main function of the probe 61 of the human body sensor 6 is to detect the presence of a human body. The probe 61 can be an infrared detector as described above. The main body of the human body sensor 6 is fixed on the circuit board inside the housing 2. The probe 61 extends downwards and is placed at the bottom of the housing 2. This avoids the four side walls of the housing 2 obstructing the probe 61, which would cause the detection distance L of the probe 61 to be too small. This ensures that the probe 61 has a wider detection distance L, thereby improving the accuracy of human body recognition and response speed, and thus improving the sensitivity of the lamp panel illumination.

[0067] Based on the above embodiments, as a further preferred option, please refer to... Figure 1 The solar lighting device also includes a diffuser plate 7, which is located at the bottom of the housing 2. The diffuser plate 7 has a limiting hole 71, into which the probe 61 is inserted.

[0068] It should be noted that the diffuser plate 7 is a plate with high light transmittance and good light diffusion effect. Common types include PC diffuser plate 7 and acrylic diffuser plate 7.

[0069] The diffuser plate 7 is located at the bottom of the housing 2, which can evenly distribute the light from the lamp panel, making the light softer and more uniform, thereby avoiding glare or overexposure and providing a more comfortable lighting experience. In addition, the diffuser plate 7 is provided with a limiting hole 71, into which the probe 61 of the human body sensor 6 can be inserted to fix it on the diffuser plate 7, thereby preventing the diffuser plate 7 from blocking the probe 61 from detecting human bodies.

[0070] Based on the above embodiments, as a further preferred option, please refer to... Figure 1 The solar lighting device also includes a reflector cup 8, and the interior of the housing 2 is provided with a support plate 9 adjacent to the diffuser plate 7. The support plate 9 is provided with a through hole 91 for the probe 61 to pass through, and the support plate 9 is also provided with a light guide hole.

[0071] The second end of the reflector cup 8 is located on the support plate 9 and is connected to the light guide hole. The first end of the reflector cup 8 is fitted with the lamp plate. From the first end to the second end of the reflector cup 8, the horizontal area of ​​the reflector cup 8 gradually increases.

[0072] Specifically, the support plate 9 is installed inside the housing 2 and adjacent to the diffuser plate 7, leaving sufficient space between the support plate 9 and the lamp panel for the reflector cup 8 to be placed. The second end of the reflector cup 8 is fixed to the support plate 9 and connects to the light guide hole on the support plate 9. The first end of the reflector cup 8 is fitted into the lamp panel. In this way, the light from the lamp panel can be concentrated onto the diffuser plate 7 through the reflector cup 8. Since the cross-sectional area of ​​the reflector cup 8 gradually increases from its first end to its second end, the light diffusion range can be gradually adjusted, making the light more evenly illuminate the diffuser plate 7, thereby enhancing the illumination effect of the lamp panel. In addition, the support plate 9 has a through hole 91 corresponding to the limiting hole 71. The probe 61 of the human body sensor 6 can pass through the through hole 91 and be inserted into the limiting hole 71 to prevent the support plate 9 from obstructing the fixed installation of the probe 61.

[0073] Furthermore, please refer to Figure 1 and Figure 3 A sealing plate 10 is provided on the end face of the diffuser plate 7 facing away from the support plate 9. The sealing plate 10 has a light-transmitting hole 101 at the position corresponding to the light guide hole. Thus, the light beam from the lamp board is uniformly diffused by the diffuser plate 7 and then emitted from the light-transmitting hole 101. The sealing plate 10 not only protects the diffuser plate 7 but also controls the light distribution, thereby ensuring uniform and efficient illumination. In addition, the sealing plate 10 has a plug-in hole 102 communicating with the limiting hole 71. The probe 61 of the human body induction sensor 6 can be installed in the limiting hole 71 with its head protruding from the plug-in hole 102 to prevent the sealing plate 10 from blocking the probe 61 from detecting.

[0074] Based on the above embodiments, as a further preferred option, please refer to... Figure 1 and Figure 2The bracket 1 has a U-shaped structure. The driver 5 is located on the right inner wall of the housing 2. The rotating shaft 51 of the driver 5 passes through the right side wall of the housing 2 and is rotatably connected to the first side wall of the bracket 1. The second side wall of the bracket 1 is rotatably connected to the left side wall of the housing 2.

[0075] Specifically, the support 1 adopts a U-shaped structure, which not only has good load-bearing capacity, but also forms a space between the two side walls of the U-shaped support 1 for placing the box 2, thereby improving the structural compactness of the device.

[0076] Furthermore, the actuator 5 is mounted on the inner right side wall of the housing 2 via a fastener (e.g., bolt). The rotating shaft 51 of the actuator 5 passes through the right side wall of the housing 2 and is inserted into the first side wall of the bracket 1, with a clearance fit to achieve a rotatable connection between the two. The left side wall of the housing 2 can be connected to the second side wall of the bracket 1 via a rotating shaft. In this way, the axis of rotation of the housing 2 is perpendicular to the straight line connecting the two side walls of the bracket 1, and the rotating shaft 51 of the actuator 5 can drive the housing 2 to rotate relative to the side wall of the bracket 1. It should be noted that the above-described arrangement of the actuator 5 makes the structure of the device more compact.

[0077] Based on the above embodiments, as a further preferred option, please refer to... Figure 1 The left side wall of the housing 2 is provided with a guide rod 11, and the second side wall of the bracket 1 is provided with a fan-shaped guide groove 12. The guide rod 11 can be slidably inserted into the fan-shaped guide groove 12; and the central angle of the fan-shaped guide groove 12 is 90 degrees. When the guide rod 11 is located in the middle position of the fan-shaped guide groove 12, the vertical line between the top and bottom of the housing 2 is perpendicular to the side wall of the bracket 1 and does not intersect.

[0078] It should be noted that the tilt angle of solar panel 3 refers to the tilt angle relative to the horizontal plane. The tilt angle of solar panel 3 should be the same as the latitude of the location, usually between 0 degrees and 45 degrees, so as to maximize the absorption of sunlight.

[0079] Taking the horizontal installation of bracket 1 on the wall as an example, specifically, the bottom wall of bracket 1 is installed on the wall by a fixing component, and the two side walls of bracket 1 are horizontally suspended. When the guide rod 11 rotates to the middle position of the fan-shaped guide groove 12, the top of the box 2 is horizontally upward, so the solar panel 3 is horizontally upward and the diffuser plate 7 is horizontally downward, and the tilt angle of the solar panel 3 and the diffuser plate 7 is 0 degrees. When the guide rod 11 rotates to the lower groove end of the fan-shaped guide groove 12, the top of the box 2 rotates 45 degrees clockwise relative to the wall, and the tilt angle of the solar panel 3 is 45 degrees. When the guide rod 11 rotates to the upper groove end of the fan-shaped guide groove 12, the bottom end of the box 2 rotates 45 degrees counterclockwise relative to the wall, and the tilt angle of the diffuser plate 7 is -45 degrees.

[0080] Therefore, as Figure 4As shown, during the day, the rotation of solar panel 3 can be controlled between 0 and 45 degrees by repeatedly detecting the voltage of solar panel 3, thus rotating it to a suitable power generation angle. Optimally, solar panel 3 is tilted at 45 degrees in the morning and afternoon, and at 0 degrees at noon, thereby maximizing sunlight absorption. Figure 5 and 6 As shown, at night, the diffuser plate 7 can be rotated between 0 degrees and -45 degrees according to the user's lighting needs, so as to rotate the diffuser plate 7 to a suitable lighting angle.

[0081] Therefore, in the above structure, the fan-shaped guide groove 12 and the guide rod 11 are rotated together to achieve the limited angle of rotation of the box 2, so as to ensure that the solar panel 3 can fully absorb sunlight during the day and the lamp panel can provide flexible and comfortable lighting through the diffuser plate 7 at night.

[0082] Based on the above embodiments, as a further preferred option, please refer to... Figure 1 The solar lighting device also includes a first buckle 13 and a second buckle 14. The first buckle 13 is detachably located in the middle of the bottom wall of the bracket 1, and the second buckle 14 is used for detachable installation on the ground or wall and is matched with the first buckle 13.

[0083] Therefore, the fixing component uses a first snap-fit ​​buckle 13 and a second snap-fit ​​buckle 14. First, the first snap-fit ​​buckle 13 is installed on the bottom wall of the bracket 1 with bolts. Then, the second snap-fit ​​buckle 14 is installed on the ground or wall with bolts. Finally, the first snap-fit ​​buckle 13 is snapped onto the second snap-fit ​​buckle 14, thus fixing the device to the ground or wall. This installation method is simple, quick, saves installation time, and is convenient for assembly and disassembly. In addition, the first snap-fit ​​buckle 13 is located in the middle of the bottom wall of the bracket 1, which can prevent the bracket 1 from tilting and improve the stability and firmness of the bracket 1 installation.

[0084] Based on the above embodiments, as a further preferred option, please refer to... Figure 1 The first buckle 13 and the second buckle 14 have the same structure. Both include a U-shaped plate 141 and an insert plate 142. The top wall of the U-shaped plate 141 is connected to the insert plate 142 on one side along the width direction. The bottom walls on both sides of the U-shaped plate 141 in the first buckle 13 are detachably connected to the bottom wall of the bracket 1. The bottom walls on both sides of the U-shaped plate 141 in the second buckle 14 are used to detachably connect to the ground or wall. The insert plate 142 in the first buckle 13 is inserted into the U-shaped plate 141 in the second buckle 14, and the inner side of the top wall of the U-shaped plate 141 in the first buckle 13 abuts against the insert plate 142 in the second buckle 14, so that the first buckle 13 is hung on the second buckle 14.

[0085] The first buckle 13 and the second buckle 14 have the following advantages with the above-described structure: First, the Z-shaped plate 141 has a strong load-bearing capacity, which can improve the safety and reliability of the fixing components and ensure that the device is firmly installed; Second, the first buckle 13 and the second buckle 14 have the same structure, which can be uniformly processed and manufactured, making processing convenient and saving processing costs; Third, if the device is installed on the wall, the first buckle 13 is hung on the second buckle 14, making the installation simpler and more convenient.

[0086] Based on the above embodiments, as a further preferred option, please refer to... Figure 1 The bottom walls on both sides of the Z-shaped plate 141 are provided with first mounting holes 15, and the bottom wall of the bracket 1 is provided with two second mounting holes 16. The second mounting holes 16 and the first mounting holes 15 are provided in a corresponding manner so that the fasteners 17 can pass through.

[0087] Therefore, the fasteners 17 (such as bolts or screws) can pass through the second mounting hole 16 on the bottom wall of the bracket 1, the first mounting hole 15 on the Z-shaped plate 141 in the first buckle 13, and the first mounting hole 15 on the Z-shaped plate 141 in the second buckle 14 in sequence to fix them to the wall or the ground, thereby connecting the bracket 1 and the fixing components to the wall or the ground as a whole, making the bracket 1 more firmly installed, and greatly reducing the risk of the bracket 1 easily falling off when it is only hung on the second buckle 14 by the first buckle 13.

[0088] In summary, the solar lighting device provided by this utility model has the following advantages:

[0089] First, the solar panel and the light panel are assembled on the box back to back, and the two transmit power through a circuit board. During the day, the solar panel faces outward to absorb sunlight, and at night the light panel faces outward to provide illumination. This design makes the lighting device compact, eliminates the need for cables to connect the solar panel and the light panel, makes it easy to install, saves costs, and has an aesthetically pleasing appearance.

[0090] Secondly, the solar panels can automatically adjust to the appropriate angle to obtain stronger sunlight, thereby increasing the charging capacity and extending the lighting time of the panels.

[0091] Third, the light panel can adjust the direction of the light according to the user's lighting needs, making it highly flexible in use.

[0092] Fourth, using a human body sensor to control the switch on and off of the light panel by detecting whether pedestrians are passing by can avoid wasting electricity due to prolonged lighting of the light panel, thereby saving the lighting time of the light panel and thus making the light panel light for a longer period of time.

[0093] Fifth, the overall device has a compact structure and is simple and convenient to install and disassemble.
