Description

[Technical Field] This utility model relates to the field of solar street light technology, and in particular to a solar street light with adjustable angle. [Background Technology] With the escalation of the global energy crisis and the rise of environmental awareness, solar energy, as a clean and renewable energy source, is receiving increasing attention. In urban infrastructure construction, solar streetlights have been widely used due to their energy-saving and environmentally friendly characteristics.

[0001] Most existing solar streetlights have fixed solar panels with fixed angles of light reception and illumination. They cannot be adjusted according to different installation locations or seasonal changes, which makes it difficult for solar streetlights to effectively utilize solar energy. This can also lead to problems such as incomplete lighting coverage of the target area, creating blind spots, or excessive light in some areas, resulting in wasted light resources and failing to meet actual lighting needs. [Utility Model Content] To address the technical problem that current solar streetlights have different installation angles and illumination angles that make it difficult to meet actual lighting needs, this utility model provides a solar streetlight with an adjustable angle.

[0002] To achieve the above objectives, this utility model is implemented by the following technical solution: An angle-adjustable solar street light includes a lamp body, a lighting device for providing illumination at the front of the lamp body, a solar panel at the back of the lamp body, and a mounting device for fixing the lamp body in place. The mounting device includes a mounting bracket and a first adjustment component for adjusting the angle of the mounting bracket, and a second adjustment component for adjusting the lighting angle.

[0003] By adopting the above technical solution, the installation angle of the fixing frame can be adjusted by the first adjustment component, thereby adjusting the tilt angle of the solar panel. This allows the angle of sunlight received by the solar panel to be optimized according to different installation locations or seasonal changes, thus improving luminous efficiency. Furthermore, the illumination angle of the lighting device can be adjusted by the second adjustment component, allowing the solar street light to better cover the target area and avoid lighting dead spots or waste of light resources.

[0004] As described above, in an angle-adjustable solar street light, the first adjustment component includes a first rotating shaft and a first bearing seat that rotates in conjunction with the first rotating shaft, and the bottom of the fixing frame is provided with a first through hole through which the first rotating shaft can pass.

[0005] As described above, in an angle-adjustable solar street light, the second adjustment component includes an adjustment arm, a second rotating shaft, and a second bearing seat that rotates in conjunction with the second rotating shaft. One end of the adjustment arm is provided with a second through hole through which the second rotating shaft can pass.

[0006] As described above, in an angle-adjustable solar street light, the other end of the adjusting arm is provided with a fixing hole, and both sides of the fixing frame are provided with multiple adjusting holes for cooperating with the fixing hole to adjust the lighting angle.

[0007] As described above, an angle-adjustable solar street light has multiple mounting holes on the top of the mounting bracket.

[0008] As described above, an angle-adjustable solar street light includes a reflector cup and an LED light panel disposed inside the reflector cup. The LED light panel has multiple LEDs, and each LED light panel has multiple LED beads arranged at intervals.

[0009] As described above, in an angle-adjustable solar street light, the back of the light fixture body is further provided with a fixing assembly for fixing the solar panel, the fixing assembly including a plurality of snap fasteners disposed on the side of the light fixture body.

[0010] As described above, an angle-adjustable solar street light has a battery pack inside the light fixture body that is electrically connected to the solar panel. The battery pack is used to store the electrical energy converted by the solar panel.

[0011] As described above, an angle-adjustable solar street light also includes a circuit board inside the light fixture body. The circuit board has a controller and a microwave sensor electrically connected to the controller. The controller is also electrically connected to the LED light panel to reduce the brightness of the LED light panel when a person or vehicle exceeds the detection range of the microwave sensor.

[0012] As described above, in an angle-adjustable solar street light, the sensing distance of the microwave sensor is L, where L is 9≦L≦11, and the sensing angle of the microwave sensor is 120°.

[0013] Compared with the prior art, the angle-adjustable solar street light proposed in this utility model has the following beneficial effects: 1. The solar street light proposed in this utility model adjusts the installation angle of the fixing frame through the first adjustment component, thereby adjusting the tilt angle of the solar panel. This allows for optimization of the light-receiving angle between the solar panel and sunlight according to different installation locations or seasonal changes, thus improving luminous efficiency. Furthermore, the second adjustment component can adjust the illumination angle of the lighting device, enabling the solar street light to better cover the target area and avoid lighting dead spots or wasted light resources.

[0014] 2. The solar street light proposed in this utility model also locks the adjusting arm and the fixing frame by locking the fixing hole on the adjusting arm with the adjusting hole on the fixing frame. This not only restricts the rotation of the adjusting arm, but also restricts the rotation of the lamp body. This ensures that the solar street light will not rotate as a whole due to external forces even when it encounters strong winds or vibrations, thus ensuring the stability of long-term use.

[0015] 3. The solar street light proposed in this utility model also uses a microwave sensor to detect whether a person or vehicle is passing by. If no person or vehicle is detected, the light intensity is reduced to reduce power consumption and achieve green energy saving and environmental protection.

Detailed Implementation Methods

[0018] Specific embodiments, combined with Figures 1 to 8 As shown, to further illustrate the technical solution of this utility model, an angle-adjustable solar street light includes a lamp body 1. The front of the lamp body 1 is provided with a lighting device 10 for providing illumination. The back of the lamp body 1 is provided with a solar panel 20. The lamp body 1 is provided with a mounting and fixing device 30 for fixing it. The mounting and fixing device 30 includes a fixing frame 31 and a first adjusting component 32 for adjusting the angle of the fixing frame 31. The mounting and fixing device 30 also includes a second adjusting component 33 for adjusting the lighting angle.

[0019] The fixing frame 31 is a U-shaped bracket.

[0020] In this embodiment, the solar street light adjusts the installation angle of the fixing frame 31 by adjusting the first adjustment component 32, thereby adjusting the tilt angle of the solar panel 20. This allows the light-receiving angle between the solar panel 20 and sunlight to be optimized according to different installation locations or seasonal changes, thereby improving luminous efficiency. Furthermore, the second adjustment component 32 can adjust the illumination angle of the lighting device 10, allowing the solar street light to better cover the target area and avoid lighting dead spots or wasted light resources.

[0021] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the first adjustment component 32 includes a first rotating shaft 321 and a first bearing seat 322 that rotates in cooperation with the first rotating shaft 321. The bottom of the fixing frame 31 is provided with a first through hole 311 through which the first rotating shaft 321 can pass, so that the fixing frame 31 can rotate around the first rotating shaft 321, thereby adjusting the installation angle of the fixing frame 31.

[0022] In this embodiment, when installing a solar street light, the user can manually push the mounting bracket, which will rotate around the first rotating shaft as the rotation center, thereby adjusting the light-receiving angle of the solar panel and improving the luminous efficiency. Secondly, the bearing structure of the rotating shaft and the rotating bearing can greatly reduce the frictional resistance generated during rotation, so that the user can push the mounting bracket to rotate without using too much force, making it convenient for the user to adjust the installation angle of the solar street light.

[0023] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the second adjustment component 33 includes an adjustment arm 331, a second rotating shaft 332, and a second bearing seat 333 that rotates in cooperation with the second rotating shaft 332. One end of the adjustment arm 331 is provided with a second through hole 3311 through which the second rotating shaft 332 can pass, so that the adjustment arm 331 can rotate around the second rotating shaft 332.

[0024] In a preferred embodiment, the other end of the adjusting arm 331 is provided with a fixing hole 3312, and both sides of the fixing frame 31 are provided with a plurality of adjusting holes 312 for cooperating with the fixing hole 3312 to adjust the lighting angle.

[0025] Specifically, one end of the adjusting arm 331 is sleeved on the second rotating shaft 332 through the second through hole 3311. When the lighting angle needs to be adjusted, the user only needs to manually push the adjusting arm 331. The adjusting arm 331 will rotate around the second rotating shaft as the rotation center, thereby changing the illumination angle of the lighting device 10. The multiple adjusting holes 312 on both sides of the fixing frame 31 correspond to different illumination angles of the lighting device 10. The user can adjust the illumination angle of the lighting device 10 by pushing the fixing hole 3312 at the other end of the adjusting arm 331 to align with any one of the adjusting holes 312 on the fixing frame 31 and then fixing it. In the actual installation process, the user can lock the fixing hole 3312 with different adjusting holes 312 to determine the optimal illumination angle of the lighting device 10. Secondly, when the fixing hole 3312 is locked with the adjusting hole 312, a locking structure is also formed between the adjusting arm 331 and the fixing frame 31. Furthermore, by locking the adjusting arm 331 with the fixing frame 31, the rotation of the lamp body 1 can be further locked, thereby preventing the solar street light from rotating arbitrarily.

[0026] It should be noted that the fixing method used when fixing the fixing hole 3312 and the adjusting hole 312 is a conventional fixing method. For example, bolts and nuts can be used for fixing. This application does not make specific limitations on the specific fixing method.

[0027] In this embodiment, the user manually pushes the adjusting arm, which rotates around the second rotation axis. When the fixing hole on the adjusting arm aligns with the adjusting hole 312, it locks, thus adjusting the illumination angle of the lighting device. Locking the fixing hole and the adjusting hole also locks the adjusting arm to the mounting bracket, thereby restricting the rotation of the adjusting arm. Even in the event of strong winds or vibrations, the illumination angle will not change. Furthermore, since one end of the adjusting arm is connected to the lamp body and the other end is connected to the mounting bracket, the locking of the adjusting arm and the mounting bracket forms a rigid connection structure, further restricting the rotation of the lamp body. This prevents the solar street light from rotating as a whole due to external forces, ensuring the stability of long-term use.

[0028] In a preferred embodiment, the top of the fixing frame 31 is provided with a plurality of mounting holes 311 so that the fixing frame 31 can be fixedly installed when rotated to a suitable mounting angle.

[0029] It is worth noting that when fixing the mounting bracket 31 through the fixing hole 311, conventional fixing methods such as expansion bolts can be used. This application does not make specific limitations on this. The mounting bracket 31 can be installed on the light pole or on the wall. That is, the solar street light of this application can be installed on the light pole or on the wall.

[0030] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the lighting device 10 includes a reflector cup 11 and an LED light panel 12 disposed inside the reflector cup 11. The LED light panel 12 is provided with a plurality of LED beads 13, and the plurality of LED beads 13 are arranged at intervals.

[0031] In a preferred embodiment, the reflective cup cover 11 has three LED light panels 12 inside.

[0032] In a preferred embodiment, the inner wall of the reflective cup cover 11 is a free-form surface.

[0033] In this embodiment, when the LED light panel emits light, part of the light is projected onto the target area in a straight line, while the other part of the light is diffused in all directions. When the diffused light shines on the inner wall of the light-emitting cup, it is refracted through the free-form surface of the inner wall, thus refracting the diffused light onto the target area, thereby avoiding light waste. Secondly, the LED beads on the LED light panel are arranged at intervals, which is conducive to air circulation and facilitates the dissipation of heat from the beads, thereby avoiding heat accumulation that could lead to a decrease in the performance of the beads or burnout. Furthermore, the interval arrangement of the beads helps to provide a softer and more uniform lighting effect, avoiding concentrated light emission.

[0034] In some preferred embodiments, multiple lighting devices 10 may be provided. For example, the solar street light of this application is provided with two lighting devices 10, so that the lighting range of the solar street light is wider.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the solar panel 20 includes a base plate 21 on which a plurality of solar cells 22 are disposed.

[0036] In some preferred embodiments, a waterproof strip (not shown in the figure) is provided between the base plate 21 and the lamp body 1 to improve the waterproof performance of the solar street light.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the back of the lamp body 1 is also provided with a fixing component 23 for fixing the solar panel 20. The fixing component 23 includes a plurality of snap fasteners 231 disposed on the side of the lamp body 1.

[0038] In this embodiment, the solar panel is simply attached to the snap-fit ​​position on the back of the lamp body, and the snap-fit ​​is pressed and fixed to the base plate of the solar panel to complete the fixation. Compared with the traditional screw fixing method, this reduces the cumbersome screw fixing process and saves assembly time. Moreover, the snap-fit ​​fixing method makes it convenient for users to disassemble and assemble. When the solar panel or internal components of the lamp body are damaged, the solar panel can be removed and replaced simply by loosening the snap-fit, or the internal components can be replaced, without having to disassemble the entire lamp body or damage the original fixing structure.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation, the lamp body 1 is provided with a battery pack 40 that is electrically connected to the solar panel 20, and the battery pack 40 is used to store the electrical energy converted by the solar panel 20.

[0040] In a preferred embodiment, the battery pack 40 is composed of multiple batteries connected in series. Preferably, the battery pack 40 is composed of three batteries connected in series.

[0041] Alternatively, the aforementioned battery can be a lithium battery.

[0042] In this embodiment, the battery pack inside the solar street light can store electrical energy converted from solar energy by the solar panel during the day, and output electrical energy to power the LED light panel at night or when there is insufficient light, so that it can emit light.

[0043] Furthermore, as a preferred embodiment of this solution and not a limitation, the lamp body 1 is also provided with a circuit board 50 inside. The circuit board 50 is provided with a controller 51 and a microwave sensor 52 electrically connected to the controller 51. The controller 51 is also electrically connected to the LED light panel 12 so as to reduce the brightness of the LED light panel 12 when a person or vehicle exceeds the detection range of the microwave sensor 52.

[0044] In a preferred embodiment, the sensing distance of the microwave sensor 52 is L, where L is 9≦L≦11, and the sensing angle of the microwave sensor 52 is 120°.

[0045] Alternatively, the microwave sensor 52 can be an external probe type microwave sensor.

[0046] Specifically, the microwave sensor 52 is essentially a microwave radar sensor based on the Doppler effect. When it is working, it transmits microwave signals through its internal oscillator. When a moving object such as a person or vehicle passes through the detection range of the microwave sensor 52, the moving object will change the frequency of the reflected wave of the microwave signal. At this time, after the microwave sensor captures the change in the frequency of the reflected wave, it will convert it into a high-level signal and transmit it to the controller 51. When the controller 51 receives the high-level signal, it determines that a moving object such as a person or vehicle has passed through, thereby controlling the brightness of the LED light panel 12 to be fully lit. If no person or vehicle or other moving object passes through the detection range of the microwave sensor 52, a low-level signal is output to the controller 51. When the controller 51 receives the low-level signal, it determines that no person or vehicle or other moving object has passed through, thereby reducing the brightness of the LED light panel 12.

[0047] In this embodiment, when the microwave sensor detects a person or vehicle passing by, it controls the LED light panel to be fully lit, providing sufficient illumination for the person or vehicle and reducing safety hazards for walking or driving at night. When no person or vehicle is detected, the brightness of the LED light panel is reduced to reduce power consumption and achieve green energy saving and environmental protection. In addition, the low brightness light intensity can avoid the glare caused by complete extinguishing and also reduce the impact on the night rest of the surrounding residents.

[0048] In some preferred embodiments, the controller 51 is also electrically connected to the battery pack 40 for managing the charging and discharging process of the battery pack 40.

[0049] It should be noted that the controller 51 is implemented using a control chip, which may include, but is not limited to, MCU (microcontroller unit), DSP (digital signal processing chip), FPGA (programmable gate array chip), and SOC (system-on-a-chip). Preferably, the controller 51 in this embodiment is implemented using a control chip of model STM32L051C8T6. Furthermore, the use of the controller 51 to manage the charging and discharging process of the battery pack 40 is a conventional battery management circuit design. For the specific circuit structure, existing battery management circuits can be referenced. This application does not make any improvements to the battery management circuit, and the inventive point is not in this regard. Therefore, this application does not limit the specific battery management circuit structure.

[0050] Furthermore, as a preferred embodiment of this solution and not a limitation, the front of the lamp body 1 is also provided with a power display panel 60, which is electrically connected to the controller 51 and is used to display the current power of the battery pack 40 in real time.

[0051] The working principle of this utility model is as follows: This utility model proposes an angle-adjustable solar street light. Through the coordinated operation of the first adjustment component 32 and the second adjustment component 33, the installation angle and illumination angle of the solar street light can be adjusted, thereby meeting the application needs in multiple scenarios. The specific working principle is as follows: When installing solar streetlights, users can adjust the luminous efficiency based on the actual installation environment or local seasonal changes and the angle between the solar panel 20 and sunlight. Specifically, users can manually push the mounting bracket 31, which will rotate around the first rotating shaft 321. After rotating to a suitable position, users can manually push the angle of the adjusting arm 331 to further optimize the illumination angle of the solar streetlight. During the pushing process, the adjusting arm 331 will rotate around the second rotating shaft 332. When the fixing hole 3312 on the adjusting arm 331 aligns with the adjusting hole 312 on the side of the mounting bracket 31 for a suitable illumination angle, the fixing hole 3312 and the adjusting hole 312 are fixed by bolts and nuts or other fixing methods, thereby locking the adjusting arm 331 to the mounting bracket 31. This restricts the rotation of both the adjusting arm 331 and the lamp body 1, preventing the solar streetlight from rotating due to external forces and ensuring long-term stability.
