Description

Technical Field

[0001] This invention relates to the field of solar lighting technology, and in particular to a solar-based lighting fixture and its control method. Background Technology

[0002] To conserve energy and reduce emissions, solar-powered lights are widely used for nighttime illumination. However, prolonged use generates significant heat, and current lights typically employ an open structure relying on heat sinks for passive cooling, which is ineffective. Furthermore, the open design makes the lights susceptible to impact, increasing the risk of damage. Additionally, the energy storage efficiency of solar panels decreases significantly when covered by dust or snow. Moreover, most existing solar lights are not yet able to effectively utilize the waste heat generated during illumination.

[0003] Chinese patent application CN111322571B discloses a solar LED street light with heat recovery function, including a lamp post. A support rod is fixedly connected to the right end face of the lamp post. A heat dissipation and power generation device is provided on the support rod. The heat dissipation and power generation device can dissipate heat from the LED light and generate electricity using the heat from the LED light. An air-cooling device is provided on the support rod below an air-cooled condenser. A wind speed detection device is provided on the upper end face of the air-cooled condenser. A rainfall detection device is provided on the support rod to the right of the air-cooled condenser. The rainfall detection device is used to detect the amount of external rainfall. The wind speed detection device and the rainfall detection device can jointly adjust the heat dissipation capacity of the air-cooling device. This invention can effectively utilize the waste heat generated by the LED light and has a good heat dissipation effect on the LED light. Its heat generation structure is that the evaporator absorbs the heat from the LED light, causing the working fluid in the evaporator to evaporate and generate steam. That is, the LED light absorbs heat and cools down through the working fluid in the evaporator. The steam is transported to the impeller through the steam delivery pipe and drives the impeller to work, thereby rotating the shaft. The shaft drives the generator to work and generate electricity. However, this method has limitations. Due to the limited temperature of the lamps during use, the amount of steam generated is insufficient, and the steam flow rate within the delivery pipe is slow, resulting in relatively low power generation. Furthermore, the scheme incorporates a fan for active cooling, which not only increases energy consumption but also further reduces the efficiency of heat energy generation, making the heat recovery effect unsatisfactory.

[0048] The beneficial effects of this invention are:

[0049] 1. This invention utilizes the temperature difference between the air inside the lamp body cavity and the outside air to actively direct the hot air inside the lamp body to the outside. This creates a chimney effect through the heat-conducting component, enhancing the thermal pressure difference and increasing the natural convection velocity. This ensures that the air flowing through the heat-conducting component has sufficient kinetic energy to drive the kinetic energy generator. Simultaneously, when not circulating, the air inside the lamp body cavity expands due to heat, increasing the pressure within the cavity. When the cavity is connected to the heat-conducting component, this pressure provides initial power to the airflow, ensuring that the kinetic energy of the airflow reaches the activation threshold of the kinetic energy generator, guaranteeing its normal operation. This fully utilizes thermal energy and increases the electrical energy converted by the kinetic energy generator.

[0050] 2. The present invention also uses the flow of hot air in the lamp body cavity to drive the flow of air in the battery cavity. When the outside temperature is high, the hot air in the lamp body cavity is transported to the battery cavity to heat the battery when the outside temperature is low. This keeps the battery at a suitable operating temperature as much as possible, thereby improving the battery's service life and discharge capacity.

[0051] 3. This invention effectively cleans dust from solar panels by releasing air through the heat-conducting component. When the solar panels are covered by snow, the hot air released by the heat-conducting component can also promote snow melting, ensuring that the solar panels maintain good working condition.

Detailed Implementation

[0059] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] Example 1

[0062] Current lighting fixtures generally employ an open structure, relying on heat sinks for passive cooling, but this is ineffective. Furthermore, this open design makes it easy for external objects to come into contact with the lamp body 4, increasing the risk of damage. Additionally, the energy storage efficiency of the solar panels 2 decreases once covered by dust or snow. Moreover, most existing solar lighting fixtures fail to effectively utilize the waste heat generated during light emission.

[0063] Reference Figures 1-5 This embodiment discloses a solar-based lighting fixture, including a lamp post 1, a solar panel 2 and a battery 3, as well as a lamp body 4, a battery cavity 5, a heat-conducting component and a kinetic energy generation component;

[0064] The lamp body 4 has a cavity inside, and the cavity of the lamp body 4 is connected to the solar panel 2 through a heat-conducting component. The heat-conducting component delivers the hot air in the cavity to the solar panel 2.

[0065] The battery 3 is installed inside the battery cavity 5, and the battery cavity 5 is connected to the cavity of the lamp body 4 through a heat-conducting component.

[0066] The upper part of the heat-conducting component is connected to the upper side of the solar panel 2, and the lower part of the heat-conducting component is connected to the cavity and the battery cavity 5 respectively; forming a hot air circulation channel to ensure efficient air circulation.

[0067] A kinetic energy generation component is used to convert the kinetic energy of airflow within a heat-conducting component into electrical energy; characterized in that the kinetic energy generation component includes a generator 11 and a blade 12, the generator 11 is fixedly disposed within a heat-conducting hole 6 and electrically connected to a storage battery 3, and the blade 12 is fixedly sleeved on the rotating shaft of the generator 11 and faces the diffuser section.

[0068] To achieve active heat dissipation, an axial flow fan 13 is added to the heat-conducting component. This fan is located above the heat-conducting hole 6 and at the top of the reversing valve. Although the axial flow fan 13 consumes electrical energy during operation, it provides powerful heat dissipation, particularly suitable for situations where the temperature inside the lamp body 4 cavity remains consistently high. When the axial flow fan 13 is activated, the airflow velocity inside the heat-conducting component increases significantly, thereby increasing the power generation of the kinetic energy generator. This change creates a self-sufficient energy cycle system, which not only enhances heat dissipation efficiency but also extends the lamp's lifespan, achieving highly efficient energy utilization. Through this design, the lamp can still operate stably in high-temperature environments, reducing the failure rate.

[0069] When the outside temperature is high, the hot air inside the cavity carries the hot air inside the battery cavity 5 out through the top of the heat-conducting component; when the outside temperature is low, the hot air inside the cavity is transported into the battery cavity 5. This provides insulation for the battery 3, preventing low temperatures from affecting battery performance. This design optimizes the balance between heat dissipation and insulation, significantly improving the adaptability and stability of the lamp under different environmental conditions.

[0070] The lamp body 4 includes a lampshade 401, a lamp panel 402, an air outlet 403, and an air inlet 404. The lampshade 401 is securely mounted on the lamp post 1, forming a cavity inside. The lamp panel 402 is positioned at the top of the lampshade 401. The air outlet 403 is located at the upper part of one end of the lampshade 401 and connects to the heat-conducting component. The air inlet 404 is located at the lower part of the end of the lampshade 401 away from the air outlet 403. A one-way valve is installed at the air inlet 404. The one-way valve conducts air from the outside of the lampshade 401 to the inside of the lampshade 401, ensuring that external cold air enters the lampshade 401 in one direction, enhancing air convection. The one-way valve design cleverly prevents the backflow of hot air, thereby further improving the overall heat dissipation efficiency.

[0071] Utilizing the temperature difference between the air inside the cavity of lamp body 4 and the outside environment, hot air is naturally guided to the outside. Simultaneously, the chimney effect generated by the heat-conducting component further enhances the thermal pressure difference, accelerating natural convection and ensuring sufficient kinetic energy for the air flowing within the heat-conducting component to drive the kinetic energy generator. Furthermore, when not in circulation, the air inside the cavity of lamp body 4 expands due to heat, increasing the pressure within the cavity. When the cavity is connected to the heat-conducting component, this pressure provides initial momentum for the airflow, ensuring that the kinetic energy of the airflow reaches the activation threshold of the kinetic energy generator, guaranteeing its normal operation. This fully utilizes thermal energy and increases the electrical energy converted by the kinetic energy generator.

[0072] The flow of hot air inside the cavity of the lamp body 4 not only drives the circulation of air inside the battery cavity 5, but also dissipates heat from the battery 3 when the outside temperature is high, and delivers hot air to the battery cavity 5 to heat the battery 3 when the temperature is low, thereby ensuring that the battery 3 is always at a suitable operating temperature, extending its service life and increasing its discharge capacity.

[0073] The air exhausted by the heat-conducting component cleans the dust off the solar panel 2. When the solar panel 2 is covered by snow, the hot air exhausted by the heat-conducting component also helps to melt the snow, so that the solar panel 2 is in a better working condition.

[0074] Example 2

[0075] Although the airflow rate is increased through the chimney effect and pressure difference in the technical solution of Embodiment 1, the temperature rise of the hot air inside the lampshade 401 is usually only 30-50°C, and the natural convection velocity is limited (about 0.1-0.5m / s), so the generated kinetic energy is still relatively weak. Although the pressure difference when the cavity is initially connected can bring a certain initial driving force, we have found in actual use that excessive pressure inside the lampshade 401 may damage the lamp beads on the lamp board 402.

[0076] The lamp body 4 also includes an energy storage mechanism, which includes an energy storage cavity 405, an energy storage plate 406, and an energy storage spring 407. One end of the energy storage cavity 405 is connected to the lamp cover 401. The energy storage plate 406 is slidably and sealed inside the energy storage cavity 405. The two ends of the energy storage spring 407 abut against the bottom of the energy storage cavity 405 and the energy storage plate 406, respectively.

[0077] When the air inside the lampshade 401 is heated and expands, it pushes the energy storage plate 406 to compress the energy storage spring 407, storing mechanical energy. When the lampshade 401 is connected to the heat-conducting component, the energy storage spring 407 releases energy, pushing the energy storage plate 406 to move and compressing the air inside the lampshade 401 into the heat-conducting component. The design of the energy storage mechanism solves the problem of excessive pressure inside the lampshade 401 and significantly improves the start-up speed and energy conversion efficiency of the kinetic energy generation component.

[0078] To optimize the product structure, we aim to increase the gas flow rate within the thermally conductive component and enable flexible switching of the gas flow direction. Therefore, the thermally conductive component design includes the following components:

[0079] Heat conduction hole 6 is located inside the upper part of lamp post 1;

[0080] The air inlet 7 is located below the heat conduction hole 6 and is connected to the cavity;

[0081] An exhaust block 8 is installed on the upper side of the solar panel 2 and connected to the upper part of the heat conduction hole 6;

[0082] The flow divider hole 9 has one end connected to the middle of the heat conduction hole 6 and the other end connected to the battery cavity 5.

[0083] A reversing valve is installed in the heat conduction hole 6 and located above the junction of the diversion hole 9 and the heat conduction hole 6.

[0084] To further enhance the gas flow rate within the heat-conducting component and ensure the smooth exhaust of gas from battery cavity 5, the following components are also added to the heat-conducting component:

[0085] The Venturi tube 10 is located inside the heat-conducting hole 6. The Venturi tube 10 includes, in sequence according to the gas flow direction, an intake section, a throat section, and a diffuser section.

[0086] The air inlet 7 is located in the intake section and its jet direction is towards the throat section, and the diverter 9 is connected to the intake section.

[0087] When the reversing valve is open, the gas inside the lamp cover 401 is ejected through the air inlet 7. At the same time, the intake section of the venturi tube 10 generates negative pressure due to the airflow, drawing gas from the battery cavity 5 into the venturi tube 10. Subsequently, this gas, along with the ejected gas, passes through the reversing valve and the exhaust block 8, and is finally discharged to the solar panel 2. This process not only helps with heat dissipation but also improves the working efficiency of the kinetic energy generation component. When the reversing valve is closed, the gas inside the lamp cover 401, after being ejected from the air inlet 7, can only flow back to the battery cavity 5, raising the temperature inside the battery cavity 5 and ensuring that the battery 3 operates stably at a suitable temperature.

[0088] Example 3

[0089] In the technical solution of Embodiment 2, if the battery cavity 5 is in a sealed state, when air flows inside the battery cavity 5, a pressure difference will be formed between the battery cavity 5 and the cavity of the lampshade 401, which is not conducive to the outflow and inflow of air inside the battery cavity 5. If the battery cavity 5 is in a state of communication with the outside, it is not only not conducive to protection, but also lowers the temperature inside the battery cavity 5 in winter. Even if hot air from the lampshade 401 flows into the battery cavity 5, it will quickly dissipate and fail to achieve a heating effect.

[0090] A pressure opening and closing mechanism is provided at the lower part of the battery cavity 5. The pressure opening and closing mechanism connects the battery cavity 5 to the outside when the pressure inside the battery cavity 5 is lower than a minimum set value or higher than a maximum set value. The pressure opening and closing mechanism includes:

[0091] Pressure control inlet 14 and pressure control outlet 15 are both located on the side wall of the lamp post 1 where the battery cavity 5 is located.

[0092] The pressure-controlled air inlet plate 16 and the pressure-controlled air outlet plate 17 are located inside the pressure-controlled inlet 14 and outside the pressure-controlled outlet 15, respectively.

[0093] The intake pressure control spring 18 and the exhaust pressure control spring 19 are used to drive the pressure control intake plate 16 to fit tightly against the inner wall of the pressure control inlet 14, while the exhaust pressure control spring 19 drives the pressure control exhaust plate 17 to fit tightly against the outer edge of the pressure control outlet 15.

[0094] When air flows out of the battery cavity 5, the pressure inside the battery cavity 5 decreases as the air flows out. When the pressure difference between the battery cavity 5 and the outside world exerts a thrust on the pressure control intake plate 16 greater than the elastic force of the intake pressure control spring 18, the pressure control intake plate 16 moves inward, causing the pressure control inlet 14 to be in the open state. At this time, due to the pressure difference, outside air flows into the battery cavity 5, and at the same time, the original air in the battery cavity 5 enters the venturi tube 10.

[0095] When hot air flows into the battery cavity 5 from the cavity of lampshade 401, the pressure inside the battery cavity 5 increases as the hot air flows in. During this process, the hot air entering the battery cavity 5 undergoes heat exchange. When the pressure difference between the battery cavity 5 and the outside world exerts a thrust on the pressure control outlet plate 17 greater than the elastic force of the pressure control spring 19, the pressure control outlet plate 17 moves outward, causing the pressure control outlet 15 to be in the open state. At this time, due to the pressure difference, the air in the battery cavity 5 that has undergone heat exchange flows to the outside world, while simultaneously allowing the air in the cavity of lampshade 401 to flow into the battery cavity 5.

[0096] The pressure opening and closing mechanism not only ensures the airflow inside the battery chamber 5, but also ensures the heating effect.

[0097] Example 4

[0098] A control method for solar-powered lighting fixtures includes a summer control method, which comprises the following steps:

[0099] S1, the cavity of lamp body 4 is in a sealed state, and the temperature of the air inside the cavity is monitored;

[0100] S2, when the air temperature inside the cavity exceeds the first set value, the cavity is connected to the heat-conducting component, allowing hot air to flow into the heat-conducting component and drawing the air inside the battery cavity 5 to be discharged together to the solar panel 2.

[0101] S3, In step S2, hot air flows smoothly within the heat-conducting component, thereby driving the kinetic energy generation component to operate, generating electrical energy and storing it in the battery 3;

[0102] S4. When the cavity is connected to the heat-conducting component for a set time, the cavity will automatically return to a sealed state.

[0103] Specifically, this also includes winter control methods, which include the following steps:

[0104] Sa, the cavity of the lamp body 4 is in a sealed state, and the temperature of the air inside the cavity and the battery cavity 5 is monitored;

[0105] Sb, when the air temperature inside the cavity is greater than the first set value and the air temperature inside the battery cavity 5 is greater than the second set value, the cavity is connected to the heat-conducting component, and the hot air inside the cavity enters the heat-conducting component and drives the air inside the battery cavity 5 to be discharged to the solar panel 2.

[0106] In step Sb, hot air flows in the heat-conducting component, driving the kinetic energy generation component to generate electrical energy and store it in the battery 3.

[0107] Sd, when the air temperature inside the cavity is greater than the first set value and the air temperature inside the battery cavity 5 is less than the second set value, the cavity is connected to the heat-conducting component, and the hot air inside the cavity enters the battery cavity 5 through the heat-conducting component.

[0108] Se, after the cavity is connected to the heat-conducting component for a set period of time, the cavity returns to a sealed state.

[0109] This method utilizes the heat and kinetic energy generated during the heat dissipation process of LED lamps, and recovers the electrical energy from the waste heat through a chip thermoelectric converter, thereby reducing energy loss, improving energy utilization, and keeping the lamps in an optimal working state, ensuring that the lamps can work stably for a long time.

[0110] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
