Description

Technical Field

[0001] This invention belongs to the field of energy-saving lighting technology, specifically an energy-saving street light with adjustable lighting angle. Background Technology

[0002] Streetlights are an important part of urban public infrastructure. Their core function is to provide safe and uniform lighting for roads, squares and other areas at night or in low light conditions. Traditional streetlights usually consist of a pole, cantilever, fixed-angle lampshade and internal light source. In order to reduce energy consumption, most traditional streetlights are being replaced by energy-saving streetlights powered by photovoltaic panels and batteries.

[0003] Existing photovoltaic energy-saving streetlights are based on the integration of key components such as photovoltaic panels, batteries, intelligent controllers, and LED light sources to form an independent lighting system with autonomous energy circulation. The photovoltaic panels, as the energy harvesting end, directly convert sunlight during the day into electrical energy, while the connected charge and discharge controller regulates the generated electricity and prioritizes its storage in the batteries. This solves the problem of intermittent solar energy, allowing the streetlights to provide continuous lighting at night.

[0004] The energy-saving streetlights mentioned above typically have a fixed internal lighting structure. Once installed, their beam angle is fixed and cannot be adjusted according to seasonal changes, weather conditions, or differences in pedestrian and vehicle traffic patterns on specific road sections. This not only easily leads to insufficient lighting in areas that require illumination but also easily causes light pollution in surrounding residential areas.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 6 as well as Figure 12As shown in the embodiment of the present invention, an energy-saving street light with adjustable lighting angle includes a support rod 1; a support arm 2 is fixedly connected to the top of the support rod 1; a cover 3 is fixedly connected to the end of the support arm 2 away from the support rod 1; an installation box is installed inside the cover 3; a plurality of evenly arranged drive rods 5 are installed inside the installation box; a plurality of evenly arranged worm gears 6 are fixedly connected to the surface of the drive rods 5; a worm wheel 7 is meshed with the surface of the worm gears 6; a support frame 8 is rotatably connected to both ends of the drive rods 5 and the worm gears 6, and the worm wheel 7 is located inside the support frame 8; a rotating rod 9 is rotatably connected to the surface of the support frame 8 at the corresponding position of the worm wheel 7, and the rotating rod 9 is fixedly connected to the worm wheel 7; a support frame 8 is fixedly connected to both ends of the rotating rod 9. A connecting frame 10 is included; an LED bead 11 is fixedly connected to one end of the connecting frame 10 away from the worm gear 6; a sleeve 12 is fixedly connected between the support frames 8, and the drive rod 5 is located inside the sleeve 12; a stepper motor 13 and a stepper motor 2 14 are fixedly connected inside the housing 3, and the stepper motor 13 and the stepper motor 2 14 are located at the two ends of the drive rod 5; a drive tube 15 is fixedly connected to the side of the support frame 8 near the stepper motor 2 14; the drive rod 5 and the drive tube 15 are driven by the stepper motor 13 and the stepper motor 2 14 respectively through a connecting assembly; a photovoltaic panel 16 is fixedly connected to the top of the support rod 1, and the photovoltaic panel 16 is connected to the battery inside the housing 3 through a charge and discharge controller;During operation, to facilitate adjustment of the lighting angle, this embodiment of the invention can be used. Firstly, stepper motor 13 and stepper motor 14 in this embodiment are controlled by a remote control system. The remote control system includes a control terminal, a communication module, a main controller module, and a sensor module. Specifically, the sensor module is a rotary encoder, directly mounted on the motor shaft, which measures the actual rotation angle and speed of the motor in real time. The remote control process is as follows: the user sends a control wireless signal through a control terminal, such as a remote control or mobile phone. The antenna of the communication module (e.g., RFM60) inside the housing 3 receives this wireless signal, demodulates and decodes it through internal circuitry, and then transmits it through the Serial Peripheral Interface (SPI). The data is fed to the main controller module (microcontroller MCU). The main controller module then controls the rotation of stepper motor 13 and stepper motor 14 based on the data transmitted from the communication module. Simultaneously, the sensor module continuously monitors the actual rotation angles of stepper motors 13 and 14 and transmits this data to the main controller module. The main controller module packages the angle data and sends it back to the communication module via SPI. Finally, the communication module transmits the feedback signal to the control terminal, allowing the user to understand the specific rotation angle and other information. This completes a closed-loop control cycle. Specifically, when the user needs the LED bead 11 to rotate around the drive rod 5... When the user needs to rotate the drive tube 15 via stepper motor 14, the drive tube 15 will then rotate the support frame 8 fixed to it. Since the support frames 8 in the same row are connected together by sleeves 12, the support frames 8 in the same row will rotate around the drive rod 5 under the drive of the drive tube 15, which is called rotation around the X-axis. When the user needs the LED bead 11 to rotate around the rotating rod 9, stepper motor 13 will drive the drive rod 5 to rotate, and the drive rod 5 will drive the worm gear 6 to rotate. Since the worm gear 6 meshes with the worm wheel 7, the worm wheel 7 will rotate around the rotating rod 9 under the drive of the worm gear 6, thereby causing the connecting frame 10 and the LED bead 11 to rotate around the rotating rod 9 as well, which is called rotation around the X-axis. The Y-axis rotates, thereby enabling the LED bead 11 to rotate around the X and Y axes through the cooperation of drive rod 5, worm gear 6, worm wheel 7, support frame 8, rotating rod 9, sleeve 12, and drive tube 15. This widens the rotatable angle of the LED bead 11, allowing users to more easily adjust the lighting direction of the LED bead 11 to the desired position. This ensures that the illumination angle can be adjusted according to seasonal changes, weather conditions, and differences in pedestrian and traffic patterns on specific road sections, thus providing sufficient illumination to the areas requiring lighting without causing light pollution to surrounding residential areas. Simultaneously, the photovoltaic panel 16 on top can charge the battery inside the casing 3 when there is sufficient sunlight, thus achieving energy-saving effects.

[0023] like Figures 3 to 7As shown, the connecting assembly includes a turntable 17, which is fixedly connected to the end faces of the drive tube 15 and the drive rod 5 respectively; adjacent turntables 17 are rotatably connected by a connecting rod 18; adjacent connecting rods 18 are staggered vertically; the central axis of the turntables 17 located in the middle on both sides is fixedly connected to the output shafts of stepper motor 13 and stepper motor 2 14; during operation, when the user needs to control the LED beads 11 to rotate around the X or Y axis in batches, the user will drive the turntables 17 to rotate through stepper motor 13 and stepper motor 2 14, and since the turntables 17 are connected to each other, when one turntable rotates... The other turntables 17 connected to them via connecting rods will also rotate synchronously. Finally, the turntables 17 will synchronously drive each drive rod 5 or drive tube 15 to rotate, thereby realizing batch control of LED beads 11 to rotate around the X or Y axis. At the same time, the staggered connecting rods 18 drive multiple turntables 17 to rotate synchronously. Compared with the gear transmission structure, it is simpler. The connecting rods 18 will also interfere with the output shafts of the rotating rod 9, drive tube 15, stepper motor 13 and stepper motor 2 14, limiting the rotation angle of the turntables 17, thereby avoiding excessive rotation of the rotating rod 9 or sleeve 12, which would cause the LED beads 11 to collide.

[0024] like Figure 7 As shown, the turntable 17 is threaded with screws 19 on its side; the drive rod 5 and the sleeve 12 have connecting holes 20 at the corresponding positions of the threads; the end face of the turntable 17 has engravings 21 at the screw positions, and the end faces of the sleeve 12 and the drive rod 5 have engravings at the connecting holes 20; during operation, when the user assembles the specially matched turntable 17, the user only needs to align the engravings 21 on the end face of the turntable 17 with the engravings 21 on the drive rod 5 or the drive tube 15, and then tighten the screws 19 to screw the screws 19 into the connecting holes 20, thereby simplifying the connection between the drive rod 5 and the drive tube 15 and the turntable 17, thus making it convenient for the user to assemble it.

[0025] like Figure 2 , Figure 8 and Figure 9As shown, the mounting box includes a base plate 22; side plates 23 are fixedly connected to both sides of the bottom surface of the base plate 22, and the side plates 23 are fixedly connected to the cover 3 by screws; limit grooves 24 are formed at both ends of the side of the two side plates 23 that are close to each other; baffles 25 are slidably connected between the pair of limit grooves 24, and the baffles 25 are fixed to the base plate 22 by screws; the two baffles 25 are respectively provided with rotating holes 26 at the corresponding positions of the rotating rod 9 and the drive tube 15, and the rotating holes 26 on both sides are respectively adapted to the rotating rod 9 and the drive tube 15; during operation, the drive rod 5, worm gear 6, worm wheel 7, support frame 8, rotating rod 9, sleeve 12, drive tube 15, connecting frame 10 and LED beads 11 are connected. When installing between the side plates 23, the user can first insert the drive rod 5 and drive tube 15 located at both ends into the rotating holes 26 on the surface of the two baffles 25 respectively, and then insert the two ends of the two baffles 25 into the limiting grooves 24 on the surface of the two side plates 23 respectively. Then, the baffles 25 are fixed to the surface of the base plate 22 with screws, thereby realizing the rapid assembly of the drive rod 5, worm gear 6, worm wheel 7, support frame 8, rotating rod 9, sleeve 12, drive tube 15, connecting frame 10 and LED beads 11. This further reduces the assembly difficulty. By adjusting the number and spacing of the rotating holes 26 on the surface of the baffles 25, the assembly needs of LED beads 11 of different sizes and numbers can be adapted, thereby improving the applicability of the embodiments of the present invention.

[0026] like Figure 3 and Figure 6 As shown, the rotating rod 9 has support plates 27 rotatably connected to both ends of the worm gear 6, and the support plates 27 are L-shaped. A through groove 28 is formed on the surface of the support plate 27 at the corresponding position of the rotating rod 9. A threaded post 29 is fixedly connected to the top surface of each support plate 27, and the threaded post 29 is adapted to the through groove 28. A nut 30 is threadedly connected to the surface of the threaded post 29. During operation, when the two baffles 25 are inserted into the limiting groove 24 between the paired side plates 23, the user aligns the threaded post 29 on the surface of the support plate 27 with the through groove 28 on the surface of the base plate 22, and... Finally, the rod is inserted into the through slot 28. At this point, the user screws the nut 30 onto the end of the threaded post 29 away from the support plate 27, which will firmly fix the support plate 27 to the surface of the base plate 22. This will provide support for the drive rod 5 and prevent the drive rod 5 from bending due to lack of support because it is only supported at both ends by the baffle 25. This would result in excessive resistance when the drive rod 5 rotates. At the same time, the threaded post 29 can be fixed by the nut 30, which also allows the user to easily increase or decrease the number of LED beads 11 in the same row to adapt to different usage environments.

[0027] like Figure 3 and Figure 10As shown, the top surface of the base plate 22 is provided with multiple straight plates 31, and the straight plates 31 are arranged in a one-to-one correspondence with the through grooves 28; multiple pairs of evenly arranged conductive plates 32 are fixedly connected to one side of each straight plate 31, and the positive and negative terminals of the LED beads 11 are respectively fixedly connected to a pair of conductive plates 32 located on their top; the conductive plates 32 are connected to the battery through the control circuit board; during operation, when the LED beads 11 need to be lit, the battery inside the housing 3 forms a complete circuit with the LED beads 11 through the control circuit, conductive plates 32, wires, and LED beads 11, so that the LED beads 11 can be lit smoothly, thereby avoiding the need for each LED bead 11 to be connected to the control circuit and battery through wires, thus avoiding the situation where the angle adjustment of the LED beads 11 is limited due to too many wires tangling, and also reducing the difficulty of subsequent inspection and maintenance.

[0028] like Figures 10 to 11 As shown, a guide plate 33 is fixedly connected between the pairs of support plates 27; the guide plate 33 is arc-shaped and located on the side of the worm 6 away from the worm wheel 7; during operation, when the wire between the LED bead 11 and the conductive plate 32 passes through the through groove 28 and connects to the conductive plate 32, the guide plate 33 can play a blocking and guiding role, so as to prevent the screw 38 from hooking with the wire when rotating, thereby causing the angle adjustment of the LED bead 11 to be obstructed.

[0029] like Figures 10 to 11 As shown, a groove 34 is provided on the side of the straight plate 31 near the conductive plate 32; a pair of copper plates 35 are fixedly connected in the groove 34; a slider 36 is slidably connected in the groove 34, and the conductive plate 32 is embedded in the slider 36; a conductive sheet 37 is fixedly connected on the side of the slider 36 near the copper plate 35; during operation, the required number of LED beads 11 varies depending on the usage environment. Since the conductive plate 32 is slidably connected in the groove 34 through the slider 36, and the conductive sheet 37 is in contact with the copper plate 35, the conductive plate 32 and the LED beads 11 connected by the conductive sheet 37 are connected to the control circuit and the battery. Thus, the user can insert the required number of sliders 36 and conductive plates 32 into the groove 34 according to their own needs, thereby improving the adaptability of the embodiment of the present invention to different needs.

[0030] like Figure 11As shown, the conductive sheet 37 is arc-shaped and elastic; a screw 38 is fixedly connected to the middle of the side of the slider 36 near the bottom of the groove 34; the bottom of the groove 34 has an installation groove that extends through the straight plate 31; a nut 39 is threaded onto the surface of the screw 38 away from the slider 36; during operation, when the slider 36 is inserted into the groove 34, the screw 38 on the end face of the slider 36 will insert into the installation groove on the surface of the straight plate 31, and then the user screws the nut 39 onto the screw. The end of the rod 38 away from the slider 36 fixes the slider 36 in the groove 34, thereby locking the slider 36 and preventing it from coming out of the groove 34. At the same time, since the conductive sheet 37 is arc-shaped, when the conductive sheet 37 is pressed on the copper plate 35, the conductive sheet 37 will deform due to compression. The conductive sheet 37 is also elastic, so the conductive sheet 37 will also adhere to the surface of the copper plate 35 due to its own elasticity, thereby preventing poor contact between the conductive sheet 37 and the copper plate 35 due to loosening of the screw.

[0031] like Figure 3 and Figure 10 As shown, both ends of the straight plate 31 are fixedly connected to rotating columns 40; the top surface of the base plate 22 is fixedly connected to connecting plates 41 at the corresponding positions of the rotating rod 9; the top surface of the connecting plates 41 is fixedly connected to a pair of arc-shaped plates 42, and the arc-shaped plates 42 are made of elastic material; during operation, when the user needs to fix the straight plate 31 to the top of the base plate 22, the user needs to insert the rotating columns 40 at both ends between the pair of arc-shaped plates 42 on the top of the connecting plates 41, and lock it by the two arc-shaped plates 42, thereby facilitating the user to disassemble it and thus facilitating the user to perform maintenance.

[0032] During operation, to facilitate adjustment of the lighting angle, this embodiment of the invention can be used. Firstly, stepper motor 13 and stepper motor 14 in this embodiment are controlled by a remote control system. The remote control system includes a control terminal, a communication module, a main controller module, and a sensor module. Specifically, the sensor module is a rotary encoder, directly mounted on the motor shaft, which measures the actual rotation angle and speed of the motor in real time. The remote control process is as follows: the user sends a control wireless signal through a control terminal, such as a remote control or mobile phone. The antenna of the communication module (e.g., RFM60) inside the housing 3 receives this wireless signal, demodulates and decodes it through internal circuitry, and then transmits it through the Serial Peripheral Interface (SPI). The data is fed to the main controller module (microcontroller MCU). The main controller module then controls the rotation of stepper motor 13 and stepper motor 14 based on the data transmitted from the communication module. Simultaneously, the sensor module continuously monitors the actual rotation angles of stepper motors 13 and 14 and transmits this data to the main controller module. The main controller module packages the angle data and sends it back to the communication module via SPI. Finally, the communication module transmits the feedback signal to the control terminal, allowing the user to understand the specific rotation angle and other information. This completes a closed-loop control cycle. Specifically, when the user needs the LED bead 11 to rotate around the drive rod 5... When the user needs to rotate the drive tube 15 via stepper motor 14, the drive tube 15 will then rotate the support frame 8 fixed to it. Since the support frames 8 in the same row are connected together by sleeves 12, the support frames 8 in the same row will rotate around the drive rod 5 under the drive of the drive tube 15, which is called rotation around the X-axis. When the user needs the LED bead 11 to rotate around the rotating rod 9, stepper motor 13 will drive the drive rod 5 to rotate, and the drive rod 5 will drive the worm gear 6 to rotate. Since the worm gear 6 meshes with the worm wheel 7, the worm wheel 7 will rotate around the rotating rod 9 under the drive of the worm gear 6, thereby causing the connecting frame 10 and the LED bead 11 to rotate around the rotating rod 9 as well, which is called rotation around the X-axis. The LED bead 11 rotates around the X and Y axes through the cooperation of the drive rod 5, worm gear 6, worm wheel 7, support frame 8, rotating rod 9, sleeve 12, and drive tube 15. This widens the rotatable angle of the LED bead 11, allowing users to more easily adjust the lighting direction of the LED bead 11 to the desired position. This ensures that the illumination angle can be adjusted according to seasonal changes, weather conditions, and differences in pedestrian and traffic patterns on specific road sections, thus providing sufficient illumination to the areas that need it without causing light pollution to surrounding residential areas. At the same time, the photovoltaic panel 16 on top can charge the battery inside the housing 3 when there is sufficient sunlight, thereby achieving energy saving.

[0033] When a user needs to control the rotation of LED beads 11 around the X or Y axis in batches, the user will drive the turntable 17 to rotate through stepper motor 13 and stepper motor 2 14. The turntables 17 are connected to each other, so when one turntable rotates, the other turntables 17 connected to it through the connecting rod will also rotate synchronously. Finally, the turntables 17 synchronously drive each drive rod 5 or drive tube 15 to rotate, thereby realizing the batch control of the LED beads 11 to rotate around the X or Y axis. At the same time, the staggered connecting rods 18 drive multiple turntables 17 to rotate synchronously. Compared with the gear transmission structure, it is simpler. The connecting rods 18 will also interfere with the output shafts of the rotating rod 9, drive tube 15, stepper motor 13 and stepper motor 2 14, limiting the rotation angle of the turntable 17, thereby avoiding excessive rotation of the rotating rod 9 or sleeve 12, which would cause the LED beads 11 to collide.

[0034] When assembling the special turntable 17, the user only needs to align the groove 21 on the end face of the turntable 17 with the groove 21 on the drive rod 5 or drive tube 15, and then tighten the screw 19 to screw the screw 19 into the connection hole 20, thereby simplifying the connection between the drive rod 5 and drive tube 15 and the turntable 17, thus making it convenient for the user to assemble it.

[0035] When installing the drive rod 5, worm gear 6, worm wheel 7, support frame 8, rotating rod 9, sleeve 12, drive tube 15, connecting frame 10, and LED beads 11 between the side plates 23, the user can first insert the drive rod 5 and drive tube 15 located at both ends into the rotating holes 26 on the surface of the two baffles 25 respectively, and then insert the two ends of the two baffles 25 into the limiting grooves 24 on the surface of the two side plates 23 respectively. Then, the baffles 25 are fixed to the surface of the base plate 22 with screws, thereby realizing the rapid assembly of the drive rod 5, worm gear 6, worm wheel 7, support frame 8, rotating rod 9, sleeve 12, drive tube 15, connecting frame 10, and LED beads 11. This further reduces the assembly difficulty. At the same time, by adjusting the number and spacing of the rotating holes 26 on the surface of the baffles 25, the assembly needs of LED beads 11 of different sizes and numbers can be adapted, thereby improving the applicability of the embodiments of the present invention.

[0036] When the two baffles 25 are inserted into the limiting grooves 24 between the paired side plates 23, the user aligns the threaded post 29 on the surface of the support plate 27 with the through groove 28 on the surface of the base plate 22 and finally inserts it into the through groove 28. At this time, the user screws the nut 30 onto the end of the threaded post 29 away from the support plate 27, which can firmly fix the support plate 27 to the surface of the base plate 22. This provides support for the drive rod 5 and prevents the drive rod 5 from bending due to lack of support because only both ends are supported by the baffles 25. This would result in excessive resistance when the drive rod 5 rotates. At the same time, the threaded post 29 is fixed by the nut 30, which also makes it convenient for the user to increase or decrease the number of LED beads 11 in the same row to adapt to different usage environments.

[0037] When the LED bead 11 needs to be lit, the battery inside the housing 3 forms a complete circuit with the LED bead 11 through the control circuit, conductive plate 32, and wires, so that the LED bead 11 can be lit smoothly. This avoids each LED bead 11 being connected to the control circuit and battery through wires, thus avoiding the situation where too many wires cause tangling and limit the angle adjustment of the LED bead 11. It also reduces the difficulty of subsequent inspection and maintenance.

[0038] When the wire between the LED bead 11 and the conductive plate 32 passes through the through groove 28 and connects to the wire board, the guide plate 33 can play a blocking and guiding role, so as to prevent the screw 38 from getting hooked on the wire when it rotates, which would obstruct the angle adjustment of the LED bead 11.

[0039] The required number of LED beads 11 varies depending on the usage environment. Since the conductive plate 32 is slidably connected to the groove 34 via the slider 36, and the conductive sheet 37 is in contact with the copper plate 35, the conductive plate 32 and the LED beads 11 connected by the conductive sheet 37 are connected to the control circuit and the battery. Thus, the user can insert the required number of sliders 36 and conductive plates 32 into the groove 34 according to their own needs, thereby improving the adaptability of the embodiment of the present invention to different needs.

[0040] After the slider 36 is inserted into the groove 34, the screw 38 on the end face of the slider 36 will be inserted into the mounting groove on the surface of the straight plate 31. Then, the user screws the nut 39 onto the end of the screw 38 away from the slider 36, thereby fixing the slider 36 in the groove 34 and locking the slider 36 to prevent it from coming out of the groove 34. At the same time, since the conductive sheet 37 is arc-shaped, when the conductive sheet 37 is pressed onto the copper plate 35, the conductive sheet 37 will deform due to compression. The conductive sheet 37 is also elastic, so the conductive sheet 37 will also adhere to the surface of the copper plate 35 due to its own elasticity, thereby preventing poor contact between the conductive sheet 37 and the copper plate 35 due to the loosening of the screw.

[0041] When the user needs to fix the straight plate 31 to the top of the base plate 22, the user needs to insert the rotating columns 40 at both ends between the paired arc plates 42 on the top of the connecting plate 41 and lock it by the two arc plates 42. This makes it easy for the user to disassemble and perform maintenance.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
