Description

Technical Field

[0001] This application relates to the field of street lighting technology, and in particular to a solar street light that is easy to maintain. Background Technology

[0002] Solar streetlights are lighting devices that use solar energy as their power source. With the development of solar photovoltaic technology, the environmental and energy-saving advantages of solar LED streetlights are receiving increasing attention. At the same time, solar streetlights do not require expensive power supply lines, are easy to install and maintain, and have advantages such as good stability, long lifespan, and high luminous efficiency, leading to their gradual expansion in application.

[0003] Solar street light systems typically consist of several parts, including LED light sources, drivers, solar panels, batteries, solar street light controllers, street light poles, and auxiliary wiring. They are suitable for various locations such as urban main roads, secondary roads, residential areas, factories, tourist attractions, and parking lots, and are the preferred lighting solution for energy conservation, emission reduction, and the use of renewable energy.

[0004] During the use of solar streetlights, some malfunctions are inevitable in various components. When maintaining existing solar streetlights, in order to ensure that the corresponding road section is still lit at night during the repair period, the entire solar streetlight needs to be replaced, which results in high maintenance costs.

[0005] Relevant prior art, such as Chinese patent application "An LED Street Light", application number: CN202122086318.4, discloses a housing, with a connection hole for connecting to a street light pole on the end face of the left side of the housing along the length of the housing, a mounting cavity on the top left side of the housing, and a top cover sealed at the mounting cavity, the top cover being detachably connected to the housing; a through hole is provided at the inner end of the connection hole, the through hole connecting the connection hole and the mounting cavity, a driving power supply is provided in the mounting cavity, a light source cavity is provided on the lower surface of the right side of the housing, a light source module is provided in the light source cavity, a light source pressure plate and a glass lens are provided outside the light source module, and a sealing ring is provided at the joint surface of the light source pressure plate and the glass lens with the housing.

[0006] In existing technologies, a groove is often cut into the bottom of the street light and covered with a removable bottom cover to allow maintenance personnel to inspect and repair the internal components. However, this is not the optimal solution, as maintenance personnel still need to look up to observe and operate the lights, which is somewhat inconvenient. This application proposes a new design to address this issue, facilitating the installation and maintenance of street lights. Utility Model Content

[0007] The technical problem to be solved by this application is to provide a solar street light that is easy to maintain, further optimize the outer shell structure of the street light, make it easy to open the outer shell to view its internal circuit system, and facilitate the inspection and maintenance by operators.

[0008] The technical solution adopted in this application is as follows: a solar street light that is easy to maintain, comprising an upper shell, a lower shell, and a lamp post mounting sleeve. The upper shell is a rectangular plate structure, and the top surface of the upper shell forms the mounting surface of the solar panel. An installation groove is provided at the front end of the bottom of the upper shell, and a light source assembly is installed in the installation groove. The middle part of the bottom surface of the upper shell is rotatably connected to the lower shell. The lower shell is a recessed structure with an open top surface. A control device is installed in the lower shell. A sensor is installed on the bottom surface of the lower shell, and the sensor is electrically connected to the control device. The lamp post mounting sleeve is adjustablely connected to the rear end of the lower shell. When the upper shell is flipped upward and forward relative to the lower shell, the top surface of the lower shell is opened and the control device is exposed. When the upper shell is flipped downward and backward relative to the lower shell, the top surface of the lower shell is covered by the upper shell.

[0009] Compared with the prior art, the advantages of this application are as follows: First, the upper shell is a rectangular plate structure, and the top surface serves as the mounting surface for the solar panel, which can provide stable and flat support for the solar panel, ensuring that the solar panel is firmly installed. This is conducive to the normal and efficient photoelectric conversion of the solar panel, providing a stable energy guarantee for the street light.

[0010] Secondly, the upper and lower housings are rotatably connected, with electronic components such as the control device housed within the lower housing. When maintenance is required, the upper housing can be flipped upwards and forwards, opening the top surface of the lower housing and exposing the control device. Maintenance personnel can easily observe and access the internal components, eliminating the need for complex disassembly of the entire streetlight or operating in confined spaces. This makes maintenance more convenient, saving time and effort. Flipping the upper housing downwards and backwards covers the top surface of the lower housing, effectively protecting the control device and other components inside, preventing dust and rain from entering and damaging internal components, thus extending the streetlight's lifespan.

[0011] Finally, the upper housing has a mounting groove at the front bottom for mounting the light source assembly, the lower housing has a control device installed inside, and a sensor is installed on the bottom surface of the lower housing and electrically connected to the control device. The lamp post mounting sleeve is adjustablely connected to the rear end of the lower housing. This structural layout realizes the rational distribution and integration of functional modules such as the light source, control device, sensor, and lamp post connection components, making the overall structure of the street light compact, with tight connections and coordinated operation between the components, while also facilitating targeted maintenance and adjustment.

[0012] For ease of description in this application, the end of the street lamp furthest from the lamp post is referred to as the front end, and the end of the street lamp closest to the lamp post is referred to as the rear end.

[0013] In some embodiments of this application, the bottom surface of the lower housing includes a first side, a second side, and a third side connected sequentially from front to back; the sensor is located at the junction of the first side and the second side. Dividing the bottom surface of the lower housing into multiple sides, with the sensor located at the junction of the first side and the second side, allows the sensor to better perceive environmental changes, improving the accuracy and sensitivity of the sensing, and facilitating more precise lighting control to meet the needs of different scenarios.

[0014] In some embodiments of this application, the first side surface is connected to the bottom surface of the upper housing, and the first side surface is an inclined surface. The bottom surface of the upper housing near the first side surface is also an inclined surface adapted to the first side surface. The inclined surface design of the first side surface and the bottom surface of the upper housing makes the connection between the upper and lower housings tighter and smoother, enhancing the stability of the overall structure. When facing natural environmental factors such as wind and rain, the inclined surface can guide rainwater to flow smoothly, reducing the erosion of the internal structure of the street light by accumulated water and effectively extending the service life of the street light.

[0015] In some embodiments of this application, the second side is a plane, located at the lowest point of the lower shell, with its front end smoothly transitioning to the first side and its rear end smoothly transitioning to the third side. This smoothly transitioning side structure effectively disperses stress, preventing structural damage caused by stress concentration and improving the structural strength and reliability of the lower shell.

[0016] In some embodiments of this application, the third side is a curved surface, and an adjustment groove is provided on the rear side of the bottom surface of the lower housing. The bottom surface of the adjustment groove is an arc-shaped surface, and two rows of locking teeth are provided on the bottom surface of the adjustment groove along the arc direction. The lamp post mounting sleeve includes an arc-shaped piece and a sleeve. The arc-shaped piece is adapted to the bottom surface of the adjustment groove. The arc-shaped piece is movably installed in the adjustment groove. The arc-shaped piece is in contact with the locking teeth, and the lamp post mounting sleeve moves along the adjustment groove under force.

[0017] The curved surface design and the fit between the adjustment groove and the lamp post mounting sleeve allow the streetlight to flexibly adjust its connection angle with the lamp post according to the actual installation environment. The contact connection method between the arc-shaped plate and the locking teeth ensures the stability of the connection and facilitates fine-tuning when needed. It can adapt to lamp posts of different diameters and shapes, greatly improving the versatility and ease of installation of the streetlight.

[0018] In some embodiments of this application, the solar panel is mounted on the top surface of the upper housing and is electrically connected to a control device. The control device includes a lithium battery and a controller, with the lithium battery connected to the controller. The controller is connected to both the solar panel and a sensor. The lithium battery is mounted directly above the sensor. Preferably, the lithium battery can be a lithium iron phosphate battery, which can withstand temperatures up to 60 degrees Celsius and has a lifespan of up to 5 years. The sensor can be an infrared human body sensor or a microwave sensor.

[0019] Solar panels are installed on the top surface of the upper casing, maximizing the area exposed to sunlight, improving solar energy conversion efficiency, and ensuring a sufficient energy supply for the streetlights. The centralized layout of the control devices, including the lithium battery mounted directly above the sensors, tightly integrates energy storage and control functions, facilitating management and maintenance, while also improving space utilization and ensuring the compactness and rationality of the streetlight's internal structure.

[0020] In some embodiments of this application, the control device includes a driver, and a mounting bracket bent into a U-shape is installed inside the lower housing. The controller and the driver are respectively mounted on the mounting bracket, with the controller located above the driver. A terminal block is also provided inside the lower housing, and the control device is connected to the terminal block.

[0021] The U-shaped mounting bracket design allows the controller and driver to be compactly installed within the lower housing, making efficient use of space and reducing overall size. The terminal block arrangement makes the wiring of the control unit clearer and more organized, facilitating quick location of wiring problems during inspection and maintenance, improving maintenance efficiency, and reducing the risk of wiring errors. A controller with an MPPT charging design can be selected for higher efficiency.

[0022] In some embodiments of this application, the lower housing and the upper housing are connected by two rotating components. The rotating components include a retainer and a limiting plate installed in the lower housing. The limiting plate is disposed adjacent to the retainer. The rotating components include an L-shaped insert installed on the bottom surface of the upper housing. The rotating shaft has an L-shaped structure and includes a short shaft and a long shaft that are perpendicular to each other. The bottom of the short shaft is inserted into the retainer, and the long shaft passes through the insert and the limiting plate.

[0023] The design of the two rotating components enhances the stability of the connection between the upper and lower housings, preventing loosening or wobbling during rotation. The L-shaped rotating shaft, in conjunction with the mounting bracket, insert, and limiting plate, allows the upper housing to rotate smoothly relative to the lower housing, ensuring both rotational flexibility and providing a certain degree of limiting effect when needed, thus ensuring the convenience and safety of maintenance operations.

[0024] In some embodiments of this application, the lower housing is further provided with a support assembly, which includes a support rod and a limiting strip. The limiting strip is installed on the bottom surface of the upper housing, and a limiting groove is formed in the limiting strip along its length. One end of the limiting groove is provided with a locking groove, which communicates with the limiting groove. The included angle between the locking groove and the limiting groove is an acute angle. One end of the support rod is rotatably connected to the lower housing, and the other end of the support rod is located in the locking groove. When the upper housing is flipped relative to the lower housing, the other end of the support rod moves along the locking groove. When the support rod is embedded in the limiting groove, the upper housing is supported by the support rod. At this time, the upper housing and the lower housing form a predetermined included angle.

[0025] The support components are designed to provide excellent support during the flipping and maintenance of the upper housing, keeping it at a suitable angle for easy operation by maintenance personnel. Simultaneously, the cooperation between the locking groove and the limiting groove ensures that the support rod stably holds the upper housing after being moved to the appropriate position, preventing accidental closure or wobbling. This improves safety and stability during maintenance and provides ample space and convenience for the maintenance operation.

[0026] In some embodiments of this application, the light source assembly is a surface-mount LED lamp group, which is covered by multiple lens plates. The structures of the multiple lens plates are not exactly the same, and the mounting groove is covered by a glass cover.

[0027] Mounting posts are provided at the four corners of the mounting groove. Pressure plates are detachably mounted on the mounting posts, and the pressure plates act on the corners of the glass cover to fix the glass cover.

[0028] As a light source component, surface-mount LED (SMD) light assemblies offer advantages such as small size, high brightness, and low energy consumption, providing excellent lighting effects. Multiple lens plates with different structures can effectively refract and focus light, further optimizing the lighting effect and meeting the lighting needs of different scenarios and distances. The design of the glass cover and removable clamps makes maintenance of the light source assembly more convenient. When it is necessary to replace the LED light assembly or clean the lens plate, simply remove the clamps to easily open the glass cover. After maintenance, it can be quickly restored to its original state, ensuring the normal operation of the streetlights.

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0038] A solar street light that is easy to maintain, as shown in Embodiment 1 Figure 1 , Figure 2 As shown: It includes an upper shell 1, a lower shell 2, and a lamp post mounting sleeve 3. The upper shell 1 is a rectangular plate structure. The top surface of the upper shell 1 forms the mounting surface of the solar panel 12. The upper shell 1 is a rectangular plate structure. The top surface of the upper shell 1, as the mounting surface of the solar panel 12, can provide stable and flat support for the solar panel, ensuring that it is firmly installed. This is conducive to normal and efficient photoelectric conversion, thereby providing a stable energy guarantee for the street light. The upper housing 1 has a mounting groove 4 at the front bottom end, in which a light source assembly is installed. The middle of the bottom surface of the upper housing 1 is rotatably connected to the lower housing 2. The lower housing 2 is a recessed structure with an open top surface. The control device is installed inside the lower housing 2. A sensor 7 is installed on the bottom surface of the lower housing 2 and is electrically connected to the control device. The lamp post mounting sleeve 3 is adjustablely connected to the rear end of the lower housing 2. The upper housing 1 has a mounting groove 4 at the front bottom end for installing the light source assembly. The lower housing 2 has a control device installed inside. The sensor 7 is installed on the bottom surface of the lower housing 2 and is electrically connected to the control device. The lamp post mounting sleeve 3 is adjustablely connected to the rear end of the lower housing 2. This structural layout realizes the rational distribution and integration of functional modules such as the light source, control device, sensor 7, and lamp post connection components, making the overall structure of the street light compact, with tight connections and coordinated operation between the components, while also facilitating targeted maintenance and adjustment.

[0039] The upper housing 1 flips upwards and forwards relative to the lower housing 2, opening the top surface of the lower housing 2 and exposing the control device. Conversely, the upper housing 1 flips downwards and backwards relative to the lower housing 2, covering the top surface of the lower housing 2. The upper housing 1 and lower housing 2 are rotatably connected, and electronic components such as the control device are housed within the lower housing 2. When maintenance is required, the upper housing 1 can flip upwards and forwards, opening the top surface of the lower housing 2 and exposing the control device. Maintenance personnel can easily observe and access the internal components, such as the control device, without needing to disassemble the entire streetlight or operate in a confined space. This makes maintenance more convenient, saving time and effort. The downward and backward flipping of the upper housing 1 covers the top surface of the lower housing 2, providing excellent protection for the control device inside, preventing dust and rainwater from entering and damaging internal components, thus extending the streetlight's lifespan.

[0040] For ease of description in this application, the end of the street lamp furthest from the lamp post is referred to as the front end, and the end of the street lamp closest to the lamp post is referred to as the rear end.

[0041] Example 2, as Figures 1 to 4 As shown, the bottom surface of the lower housing 2 includes a first side, a second side, and a third side connected sequentially from front to back; the sensor 7 is located at the junction of the first side and the second side. Dividing the bottom surface of the lower housing 2 into multiple sides, with the sensor 7 located at the junction of the first side and the second side, this layout allows the sensor 7 to better perceive environmental changes, improve the accuracy and sensitivity of sensing, and help achieve more precise lighting control to meet the needs of different scenarios.

[0042] The first side surface connects to the bottom surface of the upper housing 1. The first side surface is inclined, and the bottom surface of the upper housing 1, near the first side surface, is also inclined to match it. This inclined surface design of the first side surface and the bottom surface of the upper housing 1 makes the connection between the upper housing 1 and the lower housing 2 tighter and smoother, enhancing the overall structural stability. When facing natural environmental factors such as wind and rain, the inclined surface can guide rainwater to flow smoothly, reducing the erosion of the streetlight's internal structure by accumulated water and effectively extending the streetlight's service life.

[0043] The second side is a plane and is located at the lowest point of the lower shell 2. The front end of the second side smoothly transitions to the first side, and the rear end of the second side smoothly transitions to the third side. This smoothly transitional side structure can effectively disperse stress, avoid structural damage caused by stress concentration, and improve the structural strength and reliability of the lower shell 2.

[0044] The third side is a curved surface. An adjustment groove 8 is provided on the rear side of the bottom surface of the lower housing 2. The bottom surface of the adjustment groove 8 is arc-shaped, and two rows of retaining teeth 9 are arranged along the arc direction on the bottom surface of the adjustment groove 8. The lamp post mounting sleeve 3 includes an arc-shaped piece 10 and a sleeve 11. The arc-shaped piece 10 adapts to the bottom surface of the adjustment groove 8 and is movably installed within the adjustment groove 8. The arc-shaped piece 10 contacts and connects with the retaining teeth 9. The lamp post mounting sleeve 3 moves along the adjustment groove 8 under force. The curved surface design and the cooperation between the adjustment groove 8 and the lamp post mounting sleeve 3 allow the streetlight to flexibly adjust its connection angle with the lamp post according to the actual installation environment. The contact connection method between the arc-shaped piece 10 and the retaining teeth 9 ensures the stability of the connection and facilitates fine-tuning when needed, adapting to lamp posts of different diameters and shapes, greatly improving the versatility and ease of installation of the streetlight.

[0045] The rest of the contents of Example 2 are the same as those of Example 1.

[0046] Example 3, as Figures 1 to 4 As shown, the solar panel 12 is installed on the top surface of the upper housing 1. The solar panel 12 is electrically connected to the control device, which includes a lithium battery 13 and a controller 14. The lithium battery 13 is connected to the controller 14, and the controller 14 is connected to both the solar panel 12 and the sensor 7. The lithium battery 13 is installed directly above the sensor 7. The installation of the solar panel 12 on the top surface of the upper housing 1 fully utilizes the sunlight area, improves solar energy conversion efficiency, and ensures a sufficient energy supply for the streetlight. The centralized layout of the control device, including the lithium battery 13 installed directly above the sensor 7, tightly integrates energy storage and control functions, facilitating management and maintenance, while also improving space utilization and ensuring the compactness and rationality of the streetlight's internal structure.

[0047] The control device includes a driver 15. A U-shaped mounting bracket 16 is installed inside the lower housing 2. The controller 14 and driver 15 are respectively mounted on the mounting bracket 16, with the controller 14 positioned above the driver 15. A terminal block 17 is also provided inside the lower housing 2, through which the control device is wired. The U-shaped mounting bracket 16 allows the controller 14 and driver 15 to be compactly installed within the lower housing 2, making efficient use of space and reducing volume. The terminal block 17 makes the wiring of the control device clearer and more organized, facilitating quick location of wiring connection problems during inspection and maintenance, improving maintenance efficiency, and reducing the risk of wiring errors.

[0048] The lower housing 2 and the upper housing 1 are connected by two rotating assemblies. Each rotating assembly includes a retainer 19 and a limiting plate 20 installed within the lower housing 2, with the limiting plate 20 positioned adjacent to the retainer 19. The rotating assembly also includes an L-shaped insert 21 mounted on the bottom surface of the upper housing 1. A rotating shaft 22 is L-shaped and includes a short shaft and a long shaft perpendicular to each other. The bottom of the short shaft engages with the retainer 19, and the long shaft passes through the insert 21 and the limiting plate 20. The design of these two rotating assemblies enhances the stability of the connection between the upper housing 1 and the lower housing 2, preventing loosening or wobbling during rotation. The cooperation of the L-shaped rotating shaft 22 with the retainer 19, insert 21, and limiting plate 20 allows the upper housing 1 to rotate smoothly relative to the lower housing 2, ensuring both rotational flexibility and providing a certain degree of limiting when needed, thus ensuring convenience and safety during maintenance operations.

[0049] The lower housing 2 is also provided with a support assembly, which includes a support rod 26 and a limiting strip 27. The limiting strip 27 is installed on the bottom surface of the upper housing 1. A limiting groove 28 is formed in the limiting strip 27 along its length. One end of the limiting groove 28 is provided with a locking groove 29, which communicates with the limiting groove 28. The included angle between the locking groove 29 and the limiting groove 28 is an acute angle. One end of the support rod 26 is rotatably connected to the lower housing 2, and the other end of the support rod 26 is located in the locking groove 29. When the upper housing 1 is flipped relative to the lower housing 2, the other end of the support rod 26 moves along the locking groove 29. When the support rod 26 is embedded in the limiting groove 28, the upper housing 1 is supported by the support rod 26. At this time, the upper housing 1 and the lower housing 2 form a predetermined angle. The design of the support assembly can play a good supporting role when the upper housing 1 is flipped for maintenance, keeping the upper housing 1 at a suitable angle and facilitating operation by maintenance personnel. Meanwhile, the cooperation between the locking groove 29 and the limiting groove 28 ensures that the support rod 26 stably supports the upper housing 1 after it is moved to the appropriate position, preventing the upper housing 1 from closing or shaking accidentally, improving safety and stability during maintenance, and providing sufficient space and convenience for maintenance operations.

[0050] The light source assembly is a surface-mount LED light group, which is covered by multiple lens plates 32. The structures of the multiple lens plates 32 are not exactly the same. The mounting groove 4 is covered by a glass cover plate 33. Mounting posts 34 are provided at each of the four corners of the mounting groove 4. Pressure plates 35 are detachably mounted on the mounting posts 34, and the pressure plates 35 act to fix the glass cover plate 33 at its corners. As a light source assembly, the surface-mount LED light group has advantages such as small size, high brightness, and low energy consumption, providing excellent lighting effects. The multiple lens plates 32 with different structures can effectively refract and focus light, further optimizing the lighting effect and meeting the lighting needs of different scenarios and distances. The design of the glass cover plate 33 and the detachable pressure plates 35 makes the maintenance of the light source assembly more convenient. When it is necessary to replace the LED light group or clean the lens plates 32, simply remove the pressure plates 35 to easily open the glass cover plate 33. After maintenance, it can be quickly restored to its original state, ensuring the normal operation of the street light.
