Description

Technical Field

[0001] This invention belongs to the field of LED lighting technology, and more specifically, it is a photovoltaic supplemental lighting lamp suitable for rural environments. Background Technology

[0002] Currently, in my country, supplemental lighting and plant lights that use "photovoltaics + LED" to regulate the lighting environment and promote the improvement of crop quality and efficiency have emerged.

[0003] However, due to insufficient innovation in core technologies in my country's photovoltaic industry, the traditional sealed packaging of battery modules and the flat-panel unidirectional structure of photovoltaic arrays, which are still used today, result in "too much light reflection loss" in photovoltaic systems, and the photoelectric conversion efficiency is severely reduced due to the difficulty in heat dissipation of the battery panels and their high temperature.

[0004] Clearly, due to the limitations of existing rural photovoltaic technology, most plant growth supplement lights can only exist in greenhouses connected to the mains electricity, relying on the mains electricity for "supplementation." In addition, existing LED supplement lights convert 60-70% of electrical energy into heat energy, resulting in high operating temperatures and severe light efficiency degradation. These two factors combined make it difficult for existing plant supplement lights to enter the field, and they only exist in greenhouses. Even the National Southern Breeding Base rarely uses them.

[0005] In fact, the life cycle of plants is the process of converting light energy into chemical energy through photosynthesis. Improving the light environment is crucial for their growth. Therefore, it is necessary to design an LED supplemental light that can be used continuously and effectively in the field. Summary of the Invention

[0006] In view of the current state of the technology mentioned in the background section, and in order to overcome the corresponding defects in the existing technology, this invention specifically discloses a photovoltaic supplementary lighting lamp suitable for rural environments, which can better solve the problems mentioned in the background section.

[0007] To overcome the deficiencies of the existing technology, those skilled in the art provide the following technical solutions: A photovoltaic supplemental lighting system suitable for rural environments includes a lamp post, an LED lamp assembly, and a photovoltaic panel assembly installed above the LED lamp and supplying power to it. Four sets of photovoltaic panel assemblies are installed at even intervals on the front, back, left, and right sides of the lamp post. Each photovoltaic panel assembly includes a telescopic frame and several solar panels mounted on the telescopic frame. The telescopic frame includes a hinge frame formed by several hinged frames connected in sequence, a telescopic assembly, and a fixing sleeve coaxially fixed to the lamp post. The hinged frame adopts a frame structure with four connecting rods hinged end-to-end to form a parallelogram shape. A solar panel is fixedly installed on the sides of the two connecting rods at the upper part of the hinged frame, so that all solar panels form a wave-shaped layout with their ends close together. One end of the hinge frame is hinged to a spindle on the outer wall of the fixed sleeve, and the other end extends horizontally. One end of the telescopic component is mounted on the fixed sleeve, and the other end is connected to one of the hinge points of the hinge frame in its telescopic direction. During the extension process, the telescopic component can extend the hinge frame through one of the hinge points, so as to increase the included angle between two adjacent solar panels.

[0008] Furthermore, each of the telescopic components includes a bent arm, a stud, and a driven bevel gear. The four driven bevel gears are rotatably installed in the side wall near the lower end of the fixed sleeve, respectively, in the front, back, left, and right directions. The gear shaft of the driven bevel gear is rotatably installed along the radial direction of the fixed sleeve. The gear shaft is coaxially fixed with the stud. The stud is threaded into one end of the bent arm. One end of the innermost hinge frame is hinged to the outer side wall of the fixed sleeve, and its other end serves as one of the hinge points for the other end of the bent arm to be hinged. The lower end of the fixed sleeve is coaxially rotatably provided with an active bevel gear mounted on the lamp post. The active bevel gear meshes with all driven bevel gears so that when rotating, it drives all studs to rotate, causing the bent arm to extend along the hinge frame.

[0009] Furthermore, the telescopic frame includes two hinged frames spaced apart from each other, the two hinged frames being connected together by a plurality of hinged rods located at their bottom, and each hinged frame being hinged at both ends of the corresponding hinged rod; the two opposite sides of each solar panel are respectively fixed to the two connecting rods of the two opposite hinged frames.

[0010] Furthermore, the bottom end of the driving bevel gear is provided with a positioning ring coaxially fixed on the lamp post, so that the driving bevel gear can be rotated and installed, and maintain meshing with the driven gear.

[0011] Furthermore, the outer side of the positioning ring is threaded, and a locking cover is installed on the outer side of the positioning ring in a threaded fit. When the locking cover is tightened, the driving bevel gear is axially pressed and fixed.

[0012] Furthermore, the bottom end of the driving bevel gear has an integral driven gear, which meshes with the driving gear driven by the first motor, and the first motor is fixedly mounted on the lamp post.

[0013] Furthermore, it also includes an air guide component installed on the light pole between the photovoltaic panel assembly and the LED light assembly. The air guide component includes a circular cover, an air collecting hopper, and guide blades. The circular cover is coaxially rotatably installed on the light pole, and the inner end of the axial hole of the circular cover has a windproof tile coaxially along its upper edge. The side wall of the light pole inside the circular cover has several air inlets connected to the air supply channel, which delivers air to the heat-generating parts of the photovoltaic panel assembly and / or the LED light assembly. The guide blades have a plate-like structure with blade-shaped ends and a diversion ridge protruding to both sides in the middle. One end of the guide blade is fixed to one side of the top surface of the circular cover, and the other side of the circular cover is connected to the air collecting hopper. The windproof tile is set on one side of the guide blade, and when the wind blows the guide blade to a relatively stable position, the air collecting hopper is on the windward side, so that when the wind flows into the circular cover through the air collecting hopper, the air inlet at the leeward side is covered and sealed by the windproof tile.

[0014] Furthermore, the lamp post, spindle, and connecting rod and hinge rod located at the lower part of the hinge frame are all hollow tubular structures, and the hinge rod is provided with an air outlet hole that can discharge air upwards. The air supply channel also includes the tube hole of the lamp post located between the photovoltaic panel assembly and the LED lamp assembly, the upper radial channel between the fixing sleeve and the tube hole, and the lower radial channel between the LED lamp assembly and the tube hole; The upper radial channel is connected to the shaft hole of the mandrel, and the shaft hole of the mandrel is always connected to the rod hole of the corresponding connecting rod at the hinge. The rod hole of the lower connecting rod is always connected to the hinge rod at the hinge. The wind energy output from the lower radial channel blows onto the heat-generating parts of the LED light assembly.

[0015] Furthermore, the ends of the connecting rod and the spindle, and the ends of the connecting rod and the hinge rod are hinged according to the following hinge structure: the hinge end of the connecting rod has a hinge hole, the end of the hole in the hinge hole has a circular step, and the inner sidewall of the circular step is provided with a sealing ring coaxially; the hinge point between the spindle or the hinge rod and the connecting rod has a smooth hinge neck, the hinge neck is provided with several ventilation holes, the hinge neck is rotatably and sealingly installed in the hinge hole, and two sealing rings are sealed and fitted at both ends of the hinge neck.

[0016] Furthermore, the LED lamp assembly includes a lamp housing and a lamp holder for mounting the LED lamp. The lamp holder is located inside the lamp housing. The lamp housing is fixedly connected to a fixing ring via a wind guide arm. The fixing ring is coaxially fixed to the lamp post. The lower radial channel is disposed inside the fixing ring and communicates with the air duct inside the wind guide arm. The bottom of the lamp holder has several wavy heat dissipation fins, the length direction of which is consistent with the air outlet direction of the air intake channel. The lamp housing around which the heat dissipation fins are located has a hollow heat dissipation structure. Compared with the prior art, the beneficial effects of the present invention are: the present invention is designed from three aspects: power supply, heat dissipation and wind resistance, so as to comprehensively improve the use effect of the garden supplement light.

[0017] 1. The structure is reasonably designed and has a high solar energy utilization rate. Four sets of photovoltaic panels are evenly distributed in front, behind, left, and right of the light pole to form a 360° unobstructed solar energy absorption layout. With the addition of a hinged frame whose angle can be adjusted by telescopic components, the solar panel posture can be automatically adjusted according to the light intensity, so that the angle between the normal of the panel and the sunlight is less than 10°, which greatly improves the solar energy conversion efficiency. In addition, the panel has a wave-shaped layout, which increases the light-receiving area in a limited space, further improving the energy collection and ensuring a stable power supply for the LED light components.

[0018] 2. Excellent wind resistance and adaptability to complex rural environments: The wind guide component automatically tracks the wind direction through guide blades, achieving stable wind guidance without additional power. It effectively copes with the gusty weather common in rural areas, improves the overall wind resistance and service life of the device, and has the feasibility of controlling the extension component to drive the hinged frame to retract, reducing the windward area of ​​the photovoltaic panel and avoiding damage to the module under strong winds.

[0019] 3. Excellent heat dissipation effect, ensuring stable operation of components: Based on the premise of strong natural wind in a rural environment, this invention uses a wind-guiding component to actively capture natural wind and use it for local heat dissipation, achieving passive heat dissipation. Specifically, in this invention, the hollow tubular structure of the lamp post, spindle, connecting rod, and hinge rod form a complete air supply channel. After the wind energy enters the channel through the wind collector and air inlet, it blows onto the back of the solar panel through the air outlet on the hinge rod, reducing the temperature of the solar panel and improving the conversion efficiency. On the other hand, it can also blow onto the wavy heat dissipation fins at the bottom of the LED lamp holder through the air guide arm's air ducts. Combined with the hollow heat dissipation structure of the lamp shell, heat dissipation is achieved, extending the life of the LED beads and preventing high temperature from affecting the performance of the LED lamp component.

[0020] 4. Proper sealing and protection extend the device's lifespan: The hinge joints between the connecting rod and the spindle, and between the connecting rod and the hinge rod, adopt a sealing ring sealing structure to prevent rainwater and dust from entering the hollow pipe and to prevent the pipe from rusting or becoming blocked, thus affecting ventilation and heat dissipation.

[0021] In summary, based on the effects produced by the above structure, this invention can utilize existing automatic control technologies to achieve fully automatic control: for example, a central controller can be set up to automatically control the start and stop of the LED light components through a light sensor, while simultaneously linking the first motor to adjust the angle of the photovoltaic panel; it can also monitor wind speed through a wind speed sensor and automatically control the extension and retraction of the articulated frame without manual intervention; the air guiding component can also autonomously track the wind direction to achieve all-weather natural ventilation and heat dissipation, reducing manual maintenance costs, and is especially suitable for large-scale rural application scenarios.

[0022] Other functions and features of the present invention will be described in detail in the following embodiments to provide a full understanding of the concept of the present invention and to enable its practical application in production. Attached Figure Description

Detailed Implementation

[0025] Based on the accompanying drawings and the following description, the technical solutions in the embodiments of the present invention can be clearly and completely described. However, it should be understood that the embodiments mentioned herein are merely one or several specific methods of the present invention, and not all implementation structures or method steps.

[0026] like Figure 1 As shown, this invention proposes a photovoltaic supplemental lighting system suitable for rural environments, as described in this embodiment. The system utilizes high-strength, corrosion-resistant aerospace-grade aluminum alloy as its core structural material, taking into account the wind load resistance, rain resistance, and corrosion resistance requirements of rural environments. Specifically, it includes a light pole 1, an LED light assembly 4, and a photovoltaic panel assembly 2 installed above and supplying power to the LED lights. In its fabrication, the light pole 1 can be a hollow aluminum alloy round tube with an outer diameter of 120mm and a thick wall, preferably with a length of 6m or more, to fully expand the illumination range formed by the LED light assembly 4 and allow the photovoltaic panel assembly 2 to receive light for a longer period. The light pole 1 is fixedly connected to a concrete foundation at its bottom via a flange, with the concrete foundation buried at a depth of 1.5m to ensure the stability of the light pole 1 in rural environments. In this embodiment, the LED light assembly 4 is installed at a suitable position on the light pole 1 above the ground, while the photovoltaic panel assembly 2 is installed above the LED light assembly 4. Four sets of photovoltaic panel assemblies 2 are provided, evenly distributed at 90° intervals in the front, back, left, and right directions of the light pole 1, forming a 360° unobstructed solar energy absorption layout. In practice, a wind guide component 3 can also be selectively installed between the photovoltaic panel assembly 2 and the LED light assembly 4 to collect air and deliver it to the area below the photovoltaic panel or the heat dissipation part of the LED light assembly 4 for cooling. In practice, a central controller can also be equipped, which can automatically coordinate the operation of photovoltaic power supply, LED lighting, and wind-guided heat dissipation when necessary.

[0027] As one of the specific implementation structures, the detailed structural installation of the photovoltaic panel module 2 in this embodiment, as well as the telescopic frame structure and assembly, are as follows: Figures 1-2 As shown, the telescopic frame of each photovoltaic panel module 2 consists of two spaced-apart hinged frames. The two hinged frames are connected by three 600mm long hollow aluminum alloy hinge rods 203. The three hinge rods 203 are located on the lower side of the hinged frames, and the hinge rods 203 have evenly spaced upward-facing air outlet holes with a diameter of approximately 3mm-5mm. The hole spacing should be set to 50mm. Figures 1-2This hinge frame is formed by four hinged frames connected sequentially. Each hinged frame uses four hollow aluminum alloy connecting rods 201, hinged end-to-end into a parallelogram shape. On the sides of the two connecting rods 201 at the top of the hinged frame, a solar panel 5 is attached using thermally conductive silicone, resulting in a wave-like layout where all solar panels 5 are arranged end-to-end close together. The initial angle between adjacent solar panels 5 can be designed to be 30°, and can be adjusted to a maximum of 180°, meaning all solar panels 5 are laid flat. It should be noted that, to better realize this invention, the solar panel 5 used here is a type of solar panel with an insulating, heat-resistant, antifreeze, waterproof, and anti-oxidation protective layer sprayed onto the back of the battery chip, replacing the battery encapsulation backplate. This allows the back of the battery chip to directly contact the outside cold air for heat dissipation, resulting in better heat dissipation. In practice, in order to minimize the slight rotation of the aforementioned hinge rod 203 and ensure only absolute translation, a hinge rod 203 can be installed at the top of each hinge frame, directly opposite the hinge rod 203 on the lower side of the hinge frame. The two are connected by a vertically installed slide rod (not shown in the figure), that is, the two ends of the slide rod are respectively inserted into the vertically fixed guide tubes (not shown in the figure) on the upper and lower hinge rods, so that the upper and lower hinge rods 203 are connected as one, thereby preventing the hinge rod 203 from twisting and maintaining the orientation of the aforementioned air outlet.

[0028] In this embodiment, as Figure 1 , Figure 3 The connection between the hinge frame and the fixed sleeve 211 adopts a hinge structure with a spindle 202. The fixed sleeve 211 can be coaxially welded and fixed to the lamp post 1. The spindle 202 is a hollow aluminum alloy shaft, which can also be fixed to the outer wall of the fixed sleeve 211 by welding. One end of the spindle 202 extends into the hinge hole 20101 of the connecting rod 201 at the bottom of the innermost hinge frame of the hinge frame, so as to realize the cantilever support of the hinge frame.

[0029] In the above embodiments, such as Figures 1-3 As shown, this telescopic assembly includes a bent arm 204, a stud 205, and driven bevel gears 206. Specifically, four driven bevel gears 206 are provided, each rotatably mounted in the side wall near the lower end of the fixed sleeve 211 via bearings. The gear shaft 207 of the driven bevel gear 206 is radially arranged along the fixed sleeve 211, and the gear shaft 207 is coaxially welded and fixed to the stud 205, or integrally formed. During installation, the other end of the stud 205 is threaded into the internal threaded hole at one end of the bent arm 204. In this embodiment, the bent arm 204 is made of high-strength aluminum alloy and can be arranged in an "L" shape. The other end of the bent arm 204 can be hinged to a hinge point in the middle of the hinge frame via a pin. A driving bevel gear 208 is rotatably mounted on the lower end of the fixed sleeve 211 via a thrust bearing (not shown in the figure). The driving bevel gear 208 meshes with the four driven bevel gears 206 simultaneously. Figure 3On the lamp post 1 at the bottom of the active bevel gear 208, a positioning ring 209 is coaxially welded. The positioning ring 209 has an external thread on the outside, and a locking cover 210 is installed on the outside thread. When it is necessary to fix the angle of the photovoltaic panel, tightening the locking cover 210 can press and fix the shaft 207 of the active bevel gear 208.

[0030] In this embodiment, in addition to the structure described above, the following design is also possible: (e.g.) Figure 4 As shown, a driven gear 212 is integrally formed at the bottom end of the driving bevel gear 208. This driven gear 212 meshes with the driving gear 213 driven by the first motor (not shown in the figure). The first motor is fixed to the lamp post 1 by a motor bracket. The central controller automatically controls the motor's start and stop according to the light intensity to adjust the angle of the photovoltaic panels. If necessary, rainproof and windproof shielding installation is provided, and a protective shell is added. Those skilled in the art can adapt the design accordingly. When the first motor rotates forward, the driving bevel gear 208 drives the driven bevel gear 206 to rotate, the stud 205 rotates out the bent arm 204, pushing the hinge frame to extend, and the included angle of adjacent solar panels 5 increases. When the motor rotates in reverse, the hinge frame retracts, and the included angle decreases.

[0031] As another specific implementation detail, to achieve the ventilation and heat dissipation function of the aforementioned air guide component 3 utilizing natural rural winds, the hinge sealing and ventilation structure design of this embodiment is as follows: Please refer to Figures 7-10 The hinge joints between connecting rod 201 and spindle 202, and between connecting rod 201 and hinge rod 203, employ a sealed ventilation structure. Specifically, a hinge hole 20101 is provided at the hinge end of connecting rod 201, with a circular step 2010101 at the hole end. A series of sealing rings 20102, made of nitrile rubber, are coaxially mounted on the inner wall of the circular step 2010101. A hinge neck 20302 with a relatively small surface roughness is machined at the hinge joint between spindle 202 and connecting rod 201; ideally, it should be as smooth as possible. Multiple ventilation holes 20301 are evenly distributed on the hinge neck 20302. The hinge neck 20302 is rotatably and sealingly installed within the hinge hole 20101, achieving a hinged installation. Two sealing rings 20102 are respectively fitted onto both ends of the hinge neck 20302, ensuring that the hinge joint can rotate freely while achieving ventilation and sealing, preventing rainwater and dust from entering the hollow pipe.

[0032] In this embodiment, as Figure 11As shown, the LED lamp assembly 4 used in this embodiment includes a lamp housing 401, a lamp holder 402, and LED beads. The back side wall of the lamp housing 401 adopts a hollow heat dissipation structure with a hollowing rate of at least 50% to improve heat dissipation efficiency. The reason for setting the above hollow structure is that, in this embodiment, the lamp holder 402 can be a copper heat sink, installed in the center inside the lamp housing 401, with the heat sink located at the back. Multiple LED beads can be soldered onto the lamp holder 402 to meet the supplemental lighting needs of field crops. The above structural design is also referred to in conjunction with... Figure 12 The copper heat sink can be integrally formed at the bottom of the lamp holder 402 with several wave-shaped or V-shaped or W-shaped heat sink fins 403. The length direction of the heat sink fins 403 is consistent with the air outlet direction of the air duct 40401, which can maximize the effect of wind energy blowing and cooling the heat sink fins 403.

[0033] Furthermore, in this embodiment, as Figure 1 and Figure 11 As shown, the lamp housing 401 is connected to the fixing ring via at least one air guide arm 404. The fixing ring is coaxially fixed to the lamp post 1 by bolts, or fixed to the corresponding position on the lamp post 1 by welding. Based on the above structural design, as... Figure 1 , Figure 5 , Figure 6 As shown, this air guide component 3 includes a circular cover 301, an air collecting hopper 302, and guide vanes 304. The circular cover 301 is made of a lightweight material to facilitate rotation with the wind. The circular cover 301 is coaxially mounted on the lamp post 1 via bearings (not shown in the figure) at both ends. Figure 6 A semi-circular windbreak tile 303 is coaxially welded to the inner end of the shaft hole of the circular cover 301. Several air inlets 101 are evenly opened on the side wall of the lamp post 1 inside the circular cover 301 to connect with the air supply channel 6 inside the lamp post 1, thereby delivering air to the photovoltaic panel assembly 2 or the LED lamp assembly 4 for cooling. More specifically, the front and rear ends of the guide vane 304 are machined into a cutting edge shape, and the middle is integrally formed with a diversion ridge 30401 protruding to both sides, so that the guide vane 304 can better drift with the wind and achieve wind direction positioning. In specific manufacturing, one end of the guide vane 304 can be fixed to one side of the top surface of the circular cover 301 with bolts, and a trumpet-shaped wind collector 302 is welded to the other side of the circular cover 301 to collect natural wind from the fields. The windbreak tile 303 must be set against the side of the guide vane 304. During this time, when the wind blows the guide vane 304, the circular cover 301 rotates with the wind direction until the wind collection hopper 302 is on the windward side to collect natural wind. At this time, the air inlet 101 on the leeward side can be covered and sealed by the windproof tile 303, so that the wind is concentrated and flows in from the air inlet 101 on the windward side, ensuring that the wind energy enters the air supply channel 6 inside the light pole 1 efficiently and in a concentrated manner.

[0034] Specifically, in this embodiment, the air supply channel 6 is as follows: Figure 1 , Figure 3 As shown, it mainly consists of the internal tube hole of the lamp post 1, the upper radial channel 601 between the fixing sleeve 211 and the tube hole, and the lower radial channel 602 inside the fixing ring of the LED lamp assembly 4. The upper radial channel 601 is a radially arranged through hole on the side wall of the fixing sleeve 211, designed to connect with the shaft hole of the spindle 202. The shaft hole of the spindle 202 is connected to the rod hole of the lower connecting rod 201 at the hinge point (i.e., through the ventilation hole 20301 on the hinge neck 20302). The rod hole of the lower connecting rod 201 is also connected to the rod hole of the hinge rod 203 at the hinge point, allowing the airflow to be blown upwards through the air outlet on the hinge rod 203, directly blowing on the back of the solar panel 5, reducing the operating temperature of the solar panel. Furthermore, depending on the degree of folding of the solar panel, the hinge rod 203 adapts to move closer to or further away from the solar panel 5, directing the airflow towards the back of the solar panel 5 as much as possible, accelerating airflow and achieving heat dissipation. Similarly, as... Figure 11 The lower radial channel 602 mentioned above is a through hole opened on the side wall of the fixed ring, which is connected to the air intake channel 40401 in the air guide arm 404. The air can be blown through the air intake channel 40401 to the heat dissipation fins 403 at the bottom of the lamp holder 402, which can carry away the heat generated by the LED lamp assembly 4 and extend the service life of the LED lamp beads.

[0035] Finally, based on the structural design of the above embodiments, existing automatic control technologies can be adaptively integrated. For example, the central controller collects ambient light intensity through a light sensor installed on the lamp post 1. When the light intensity is lower than a set value, the LED light assembly 4 is automatically turned on for supplemental lighting; when the light intensity is higher than the set value, such as during the day, the LED lights are immediately turned off. Alternatively, a dedicated time control module can be set to automatically provide supplemental lighting for crops at set daily times. The photovoltaic panel assembly then supplies power to the supplemental lights, automatically turning them off at the designated times. Furthermore, the module automatically adjusts the corresponding spectral wavelengths at different growth stages of the plants to promote healthy plant growth. Similarly, the control of the folded solar panel 5 is also similar. Based on the light intensity, the central controller can control the first motor to start, adjusting the angle between the solar panels 5 in the photovoltaic panel assembly 2 to ensure that the solar panels 5 always maintain the optimal light-receiving posture. In practice, this can also be achieved by tracking the solar altitude angle, ensuring that the angle between the normal of the solar panel and the sunlight is less than 10°. In addition, the central controller can monitor wind speed via a wind speed sensor. When the wind speed exceeds a set value, it controls the first motor to retract the hinged frame, reducing the windward area of ​​the photovoltaic panels and preventing damage to the components. When the wind speed decreases, it controls the hinged frame to extend, restoring the optimal angle of sunlight and preventing damage from strong winds. As for the air guide component 3, it can automatically track the wind direction via guide vanes 304, requiring no additional power to achieve all-weather natural ventilation and heat dissipation, ensuring stable operation of the entire device in complex rural environments. During ventilation, selective ventilation can be provided to the photovoltaic panels and LED lights, specifically as follows: Figure 1 As shown, two sealing blocks (not shown in the figure) are installed on the lamp post 1. The section of the lamp post 1 between the two sealing blocks serves as the main channel of the aforementioned air supply channel 6. A valve plate 9 is installed in the holes of the lamp post 1 at both the upper and lower ends of the aforementioned circular cover 301. (See also...) Figure 13 The valve plate 9 is fixed to the shaft of the drive gear 7, and the drive gear 7 is connected to a second motor (not shown in the figure) outside the lamp post 1. By rotating the valve plate 9, the corresponding air supply channel 6 is opened, so that the air is concentrated and delivered to the photovoltaic panel module 2 or the LED lamp module 4. Generally, during the day, air is mainly supplied to the photovoltaic panel module 2 for heat dissipation, while at night, air is supplied to the LED lamp module 4 for heat dissipation. In addition, an external interface 8 can be reserved on the lamp post 1 for maintenance, or an additional cooling fan can be connected to supply air for active cooling when there is no wind.

[0036] This invention is not limited to the field covered by this embodiment. Some well-known structures or principles have not been further described. However, those skilled in the art can theoretically know all the well-known technologies in this field prior to the application date or priority date, and can fully master all the prior art in this field. They also have the means and ability to apply these prior art in practical design. Under the technical guidance provided in this application, those skilled in the art can more comprehensively improve and implement this invention by combining their own capabilities. Furthermore, it should be noted that although the text and graphics of the above embodiments have shown specific implementation scenarios of the invention, those skilled in the art can make various obvious extensions and expansions to these embodiments without departing from the design concept of the invention, forming different embodiments. However, this does not affect the fact that the scope of protection of the invention is covered and embodied by the technical features of this claim and equivalent technical features.
