[0002] Solar-powered LED streetlights are outdoor lighting devices that integrate renewable energy and high-efficiency lighting technologies. They mainly consist of solar photovoltaic panels, LED light sources, energy storage batteries, intelligent controllers, and the lamp body structure. Their core principle is to convert light energy into electrical energy through photovoltaic panels, store it in batteries, and then use the controller to drive the LEDs to emit light, achieving nighttime illumination. They feature no need for external mains power, low carbon emissions and environmental friendliness, intelligent dimming, and adaptability to remote areas. They effectively solve the problems of high energy consumption and complex wiring associated with traditional streetlights, and are widely used in urban roads, rural roads, parks, and other scenarios, representing a typical application of green lighting combined with distributed energy.

[0003] For example, an LED solar street light device with announcement number CN219933775U includes an LED solar street light body, a cleaning mechanism, a light control circuit, and a control circuit. The cleaning mechanism includes a motor reduction mechanism, a lead screw, a sliding plate, a power switch, and a linear shaft. One end of the lead screw is installed before the power output shaft of the motor reduction mechanism. The motor reduction mechanism is installed at one end of one side of the solar panel frame, and a bearing seat is installed at the other end of the solar panel frame. The other end of the lead screw is fitted inside the inner ring of the bearing. The linear shaft is installed on the other side of the solar panel frame. One end of the sliding plate is threaded to the lead screw, and the inner ring of the linear bearing of the sliding plate is fitted outside the linear shaft. A micro-power switch is installed at both ends of the solar panel frame. The light control circuit and the control circuit are installed in a component box and electrically connected to the motor reduction mechanism. This new device can automatically clean the snow when it obstructs the sunlight on the solar panel surface, ensuring the power generation effect of the solar panel.

[0004] Based on the search of patent numbers, and combined with the shortcomings of existing technologies, the following findings were made;

[0005] Existing solar LED streetlights lack heat insulation and rapid heat dissipation structures. The LED chips and energy storage batteries are not thermally isolated, causing the junction temperature of the LED chips to rise continuously under high temperature conditions, which accelerates the aging of phosphors. The battery compartment is kept at a high temperature for a long time due to heat accumulation, which intensifies the decomposition of lithium battery electrolyte. In low-temperature environments, batteries without heat preservation measures experience a sharp drop in discharge efficiency at low temperatures, resulting in a significant reduction in battery life and reducing the effectiveness of solar LED streetlights.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model solves the problems of insufficient heat insulation and rapid heat dissipation in existing solar LED streetlights by setting up a heat-insulating connection component in conjunction with a heat-conducting heat dissipation component to insulate and quickly dissipate heat from LED beads and battery boxes. This solves the problems of insufficient heat insulation and rapid heat dissipation structure in existing solar LED streetlights, lack of thermal isolation between LED beads and energy storage batteries, resulting in continuous rise of LED chip junction temperature under high temperature environment, accelerated phosphor aging, battery compartment being at a high temperature for a long time due to heat accumulation, accelerated decomposition of lithium battery electrolyte, and battery without heat insulation measures experiencing a sharp drop in discharge efficiency at low temperature environment, resulting in a significant reduction in battery life and reduced performance of solar LED streetlights.

[0017] 2.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 4 As shown, the solar LED street light with a heat insulation and heat dissipation structure provided by this utility model includes an LED street light body 1, a solar panel 2, a battery box 3, LED beads 4, and a connecting rod 5. The solar panel 2 is installed on the top of the LED street light body 1, the battery box 3 is installed on one side of the bottom of the LED street light body 1, and the battery box 3 is installed with the connecting rod 5 through a gear linkage mechanism. The LED beads 4 are installed on the other side of the bottom of the LED street light body 1. A heat insulation connection component 6 is provided at the bottom of the LED street light body 1, and a heat conduction and heat dissipation component 7 is installed on one side of the bottom of the LED street light body 1.

[0026] refer to Figure 4 The heat insulation connection assembly 6 includes a mounting groove 61, an insulation plate 62 is installed inside the mounting groove 61, an insulation box 63 is installed on the outside of the battery box 3, a fixing groove 64 is opened on one side of the insulation box 63, and a heat-conducting rod 65 is provided on the outside of the LED beads 4.

[0027] As a technical optimization of this utility model, by setting up a heat insulation connection component 6, in which the heat insulation plate 62 in the mounting groove 61 and the heat insulation box 63 on the outside of the battery box 3 can effectively prevent the heat generated by the LED beads 4 from being transferred to the battery box 3, thereby achieving thermal isolation between the LED beads 4 and the energy storage battery. This avoids the battery being in a high-temperature environment due to the heat generated by the LED beads 4, further ensuring the stability of battery performance and extending the battery's service life. The heat conduction rod 65 can work with the unidirectional heat conduction column 15 to conduct and dissipate the heat generated by the LED beads 4.

[0028] refer to Figure 4 The heat conduction and heat dissipation assembly 7 includes a heat conduction block 71, which is installed on one side of the battery box 3. The heat conduction block 71 is located inside the fixing groove 64. The other end of the heat conduction rod 65 is installed on the outside of the heat conduction block 71. A one-way heat conduction plate 72 is provided on the other side of the heat conduction block 71, and a heat dissipation fin 73 is installed on the other side of the one-way heat conduction plate 72.

[0029] As a technical optimization of this utility model, by setting up a heat conduction and heat dissipation component 7, the heat conduction block 71, the one-way heat conduction plate 72 and the heat dissipation fins 73 cooperate with each other to quickly conduct the heat generated by the LED beads 4 and the electromagnetic box away. The heat conduction block 71 transfers the heat of the LED beads 4 to the one-way heat conduction plate 72. The one-way heat conduction plate 72 only allows the heat to be transferred unidirectionally to the heat dissipation fins 73, and the heat dissipation fins 73 then dissipate the heat to the surrounding environment, which greatly improves the heat dissipation efficiency, ensures that the LED beads 4 work at a suitable temperature, reduces light decay, and ensures the lighting brightness of the street light.

[0030] refer to Figure 3 A temperature sensor 8 is installed on one side of the battery box 3. The temperature sensor 8 is electrically connected to a controller 9 via a wire. The controller 9 is installed on the front of the LED street light body 1. The controller 9 is electrically connected to a remote controller 10 via a wire.

[0031] As a technical optimization of this utility model, by setting a temperature sensor 8, a controller 9 and a remote controller 10, the temperature sensor 8 can monitor the temperature of the battery box 3 in real time. When the temperature is too high or too low, it will transmit the signal to the controller 9. Through the connection with the remote controller 10, the staff can remotely obtain the temperature information of the street light, discover potential problems in time and deal with them, realize the monitoring of street light temperature, and improve the convenience and intelligence of street light management.

[0032] refer to Figure 4 A copper block 11 is provided on the inner side of the unidirectional heat conduction plate 72 and the heat conduction block 71. A heat insulation block 12 is installed on the top of the copper block 11. An electric push rod 13 is installed on the top of the heat insulation block 12. The electric push rod 13 is installed at the bottom of the LED street light body 1. The controller 9 is electrically connected to the electric push rod 13 through a wire.

[0033] As a technical optimization of this utility model, by setting a copper block 11, a heat insulation block 12, and an electric push rod 13, the electric push rod 13 can extend and retract according to the instructions of the controller 9. When the temperature of the battery box 3 is too high, the electric push rod 13 extends and pushes the copper block 11, so that the one-way heat conduction block 71 contacts the one-way heat conduction plate 72, effectively dissipating heat. When the temperature drops to a certain level, the electric push rod 13 retracts, so that the heat insulation block 12 moves between the heat conduction block 71 and the one-way heat conduction plate 72, avoiding excessive heat dissipation and avoiding the situation that affects the use of the battery box 3 in a low-temperature environment. At the same time, in a low-temperature environment, the heat generated by the LED beads 4 will automatically heat the inside of the heat insulation box 14 through the one-way heat conduction column 15, the heat conduction rod 65, the heat conduction block 71, and the heat conduction sheet, improving the use effect of the battery box 3 in a low-temperature environment.

[0034] refer to Figure 3 A heat insulation box 14 is provided on the outside of the heat-conducting rod 65, and the heat-conducting rod 65 is located inside the heat insulation box 14. A one-way heat-conducting column 15 is installed on the outside of the LED bead 4, and the outside of the one-way heat-conducting column 15 is installed on the inside of the heat-conducting rod 65.

[0035] As a technical optimization of this utility model, by setting up a heat insulation box 14 and a one-way heat conduction column 15, the heat insulation box 14 wraps around the heat conduction rod 65, further preventing heat loss during the conduction process and improving the efficiency and stability of heat conduction. The one-way heat conduction column 15 ensures that the heat generated by the LED bead 4 can only be transferred to the heat conduction rod 65 in one direction, avoiding reverse heat transfer and ensuring that the heat can be effectively conducted out, thereby enhancing the overall heat insulation and heat conduction performance.

[0036] refer to Figure 3 A heat sink 16 is installed on the outside of the heat sink 73. The heat sink 16 is installed on the outside of the LED street light body 1. A heat absorption plate 17 is installed on the side of the heat sink 16 near the battery box 3.

[0037] As a technical optimization of this utility model, by setting up a heat dissipation plate 16 and a heat absorption plate 17, and wrapping the heat conduction rod 65 with a heat insulation box 14, heat loss during conduction is further prevented, improving the efficiency and stability of heat conduction. The unidirectional heat conduction column 15 ensures that the heat generated by the LED bead 4 can only be transferred to the heat conduction rod 65 in one direction, avoiding reverse heat transfer and ensuring that the heat can be effectively conducted away, thus enhancing the overall heat insulation and heat conduction performance.

[0038] refer to Figure 3 A protective box 18 is provided on the outside of the controller 9. The protective box 18 is installed on the front of the LED street light body 1, and the remote controller 10 is installed inside the protective box 18.

[0039] As a technical optimization of this utility model, by setting up a protective box 18, which is installed on the front of the LED street light body and houses the controller 9 and remote controller 10 inside it, the corrosion of the controller 9 and remote controller 10 by external factors such as rain and dust can be effectively prevented, protecting the normal operation of these control devices, reducing street light failures caused by equipment damage, and improving the reliability of the street light system.

[0040] The working principle and usage process of this utility model are as follows: When in use, the solar panel 2 is installed on the top of the LED street light body. During the day when there is sunlight, it uses the photovoltaic effect to convert sunlight into electrical energy. This electrical energy is transmitted to the battery box 3 located on one side of the bottom of the LED street light body. The energy storage battery in the battery box 3 stores the electrical energy, providing energy security for subsequent street light lighting. This process is the basis for the street light to achieve independent power supply and lighting, so that the street light does not need to rely on the mains power and has advantages such as low carbon and environmental protection and adaptability to remote areas.

[0041] When night falls or the ambient light intensity falls below a set threshold, the intelligent control system activates. Under the control of the controller 9, the electrical energy in the battery box 3 is transferred to the LED beads 4 installed on the other side of the bottom of the LED street light body. The LED beads 4 emit light under the influence of the electrical energy, illuminating the surrounding area. The controller 9 can achieve intelligent dimming based on preset programs or ambient light information from a light sensor. For example, it can reduce the brightness of the LED beads 4 when there are few pedestrians and vehicles at night to save energy, extend battery life, and meet lighting needs at different times of day.

[0042] The LED bead 4 generates a large amount of heat during operation. To prevent this heat from affecting battery performance, the heat insulation plate 62 inside the mounting slot 61 and the heat insulation box 63 outside the battery box 3 effectively prevent the heat generated by the LED bead 4 from being transferred to the battery box 3, achieving thermal isolation between the LED bead 4 and the energy storage battery. The unidirectional heat-conducting column 15 on the outside of the LED bead 4 ensures that heat can only be transferred in one direction to the heat-conducting rod 65, and then the heat-conducting rod 65 conducts the heat away, preventing the heat from being transferred back to the battery box 3. This ensures that the battery operates stably at a suitable temperature and extends the battery's lifespan. The heat-conducting rod 65 transfers the heat from the LED bead 4 to the heat-conducting block 71, which is located on one side of the battery box 3 and in the fixing slot 64 of the heat insulation box 63. The heat-conducting block 71 transfers the heat to the unidirectional heat-conducting plate 72, which only allows heat to be transferred in one direction to the heat dissipation fins 73. The heat dissipation fins 73 dissipate the heat to the surrounding environment by increasing the heat dissipation area. The heat dissipation plate 16 on the outside of the heat dissipation fins 73 further increases the heat dissipation surface area. The battery box 3 is equipped with a temperature sensor 8 that monitors its temperature in real time. When the temperature is too high, the temperature sensor 8 sends a signal to the controller 9, which then sends a command to the electric push rod 13. The electric push rod 13 extends and pushes the copper block 11, which then conducts heat from the heat-conducting block 71 into the unidirectional heat-conducting plate 72 for heat dissipation. When the temperature drops to a certain level, the electric push rod 13 retracts, and the heat insulation block 12 moves between the heat-conducting block 71 and the unidirectional heat-conducting plate 72 to prevent excessive heat dissipation. In low-temperature environments, the heat generated by the LED beads 4 is automatically heated inside the heat insulation box 14 through the unidirectional heat-conducting column 15, the heat-conducting rod 65, the heat-conducting block 71, and the heat sink. This improves the performance of the battery box 3 in low-temperature environments, ensures normal battery discharge, maintains the street light's endurance, and achieves the effect of heat insulation and heat dissipation, thus enhancing the performance of the solar LED street light.

[0043] In summary, this solar LED street light with a heat insulation and heat dissipation structure solves the problems of existing solar LED street lights lacking heat insulation and rapid heat dissipation structures, LED chips and energy storage batteries not being thermally isolated, resulting in a continuous increase in the junction temperature of LED chips under high temperature conditions, accelerated phosphor aging, and the battery compartment being kept at a high temperature for a long time due to heat accumulation, which intensifies the decomposition of lithium battery electrolyte. In low-temperature environments, batteries without insulation measures experience a sharp drop in discharge efficiency at low temperatures, significantly reducing the battery life and lowering the performance of the solar LED street light.
