Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, specifically to an indoor energy-saving lamp. Background Technology

[0002] With the continuous expansion of indoor spaces such as industrial plants, warehousing and logistics centers, large supermarkets, and sports stadiums, the requirements for lighting brightness, energy efficiency, and stability are increasing. Indoor energy-saving lamps are gradually replacing traditional lighting fixtures and are widely used. Among them, high-bay lamps, as a typical indoor energy-saving lamp, are usually installed at a high position to provide concentrated and high-brightness lighting for large areas and high-ceilinged spaces. They are characterized by high power and long continuous working time.

[0003] To address the heat generation issue, existing indoor energy-saving lamps typically place the light source board in direct contact with the lamp's back cover. This conducts the heat generated during the light source board's operation to the back cover, where heat dissipation fins are then installed on the outside of the back cover. By utilizing the natural convection and heat exchange between the heat dissipation fins and the surrounding air, the heat is gradually dissipated into the external environment, thus completing the overall heat dissipation process.

[0004] However, the heat conduction structure between the light source board and the back cover is mostly a simple contact type. Due to factors such as assembly precision, contact area and heat conduction medium, the heat conduction efficiency is limited, and local high temperature areas are easily formed at the light source board. In addition, for indoor energy-saving lamps with high power such as high bay lights, the existing heat dissipation structure is prone to insufficient heat dissipation capacity under long-term high load operation, which affects the long-term stable operation of the lamp.

[0005] Therefore, there is an urgent need for an indoor energy-saving lamp with a more reasonable structure and better heat dissipation performance to meet the practical application requirements of high power, high reliability and long life. Summary of the Invention

[0006] The purpose of this invention is to provide an indoor energy-saving lamp to solve the technical problem that the heat dissipation structure of existing indoor energy-saving lamps is prone to heat accumulation and cannot meet the heat dissipation requirements of long-term stable operation of high-bay lamps.

[0007] To achieve this objective, the present invention adopts the following technical solution: An indoor energy-saving lamp includes a lampshade, a lamp holder, LED beads, a triggering component, a cooling component, and a heat-conducting component. The lamp holder is disposed inside the lampshade, the LED beads are disposed on the lamp holder, and the triggering component is disposed on the lamp holder for detecting and reporting the temperature of the lamp holder. The cooling component and the heat-conducting component are electrically connected to the triggering component and are used to reduce the temperature of the lamp holder. When the triggering component detects and reports that the temperature of the lamp holder is greater than a first preset value and less than a second preset value, the cooling component is activated to cool the lamp holder. When the triggering component detects and reports that the temperature of the lamp holder is greater than the second preset value, the heat-conducting component is activated to cool the lamp holder.

[0008] Optionally, the cooling assembly includes a receiving cavity, a coolant, and an adjusting component. The coolant is disposed within the receiving cavity, which includes a first chamber, a second chamber, and a third chamber connected in sequence. The first and third chambers are vertically disposed on both sides of the lamp holder, and the second chamber is horizontally disposed on the top of the lamp holder. A voltage stabilizing hole is provided on the top of the second chamber. The adjusting component is communicatively connected to the triggering assembly and is slidably disposed within the first and third chambers to adjust the position of the coolant within the receiving cavity.

[0009] Optionally, the heat-conducting component includes an air duct and a sliding member. The air duct is disposed on the outside of the lamp holder and has ventilation holes. A sliding channel is formed between the first chamber and the third chamber. The air duct is slidably installed in the sliding channel through the sliding member, wherein the sliding member is communicatively connected to the triggering component.

[0010] Optionally, the adjusting member includes a sliding plate, a first magnetic element, and a second magnetic element. The sliding plate slides along the first chamber and the third chamber. The first magnetic element is respectively disposed on the inner bottom surface of the first chamber and the third chamber. The second magnetic element is disposed on the side of the sliding plate close to the first magnetic element. The first magnetic element is an electromagnet.

[0011] Optionally, the sliding component includes a slider, a third magnetic component, and a fourth magnetic component. The slider is disposed on both sides of the air guide tube and slides along the sliding channel. The third magnetic component is disposed on the bottom surface of the second chamber, and the fourth magnetic component is disposed on the side of the slider close to the third magnetic component. The third magnetic component is an electromagnet.

[0012] Optionally, the triggering component includes a mounting base, an expansion body, a first sensing electrode, and a second sensing electrode. The mounting base is disposed on the lamp holder, the expansion body is disposed within the mounting base, and an electrode plate is disposed on the expansion body. The first sensing electrode and the second sensing electrode are disposed on the mounting base. When the lamp holder temperature is greater than a first preset value and less than a second preset value, the electrode plate is electrically connected to the first sensing electrode to form a first trigger signal. The first trigger signal is used to change the magnetic pole direction of the first magnetic component. When the lamp holder temperature is greater than the second preset value, the electrode plate is electrically connected to the second sensing electrode to form a second trigger signal. The second trigger signal is used to change the magnetic pole direction of the third magnetic component.

[0013] Optionally, a heat-conducting film is provided on the bottom surface of the second chamber, and the heat-conducting film is an arc structure with the center convex upward.

[0014] Optionally, slide rails are provided on the end faces of the first chamber and the third chamber that are close to each other, and the slider is slidably installed in the slide rails.

[0015] Optionally, a rolling element is provided inside the slide rail, the rolling element abuts against the slider, and the contact surface shape of the slider and the rolling element matches.

[0016] Optionally, a rubber pad layer is provided on the top of the air guide duct.

[0017] Compared with the prior art, the present invention has the following beneficial effects: This invention incorporates a triggering component within the indoor energy-saving lamp to monitor and provide real-time feedback on the lamp holder temperature. This allows the lamp to dynamically sense its thermal state during operation and automatically adjust its heat dissipation method based on actual temperature changes. When the lamp holder temperature is between a first and a second preset value, only the cooling component is activated to actively cool the lamp holder, suppressing temperature rise and avoiding unnecessary energy consumption. When the lamp holder temperature rises further and exceeds the second preset value, the heat-conducting component is triggered and works in conjunction with the cooling component to enhance heat dissipation, effectively preventing continuous heat accumulation and ensuring the reliability and stability of heat dissipation for high-bay lamps under long-term operating conditions. Through this graded heat dissipation mechanism, the lamp holder and LEDs are always kept in a relatively stable and suitable operating temperature environment, effectively reducing the decrease in luminous efficiency and accelerated light decay caused by high temperatures, slowing down the performance degradation rate of the LEDs, and thus extending the effective lifespan of the LEDs. Simultaneously, the lamp maintains high luminous efficiency throughout its entire lifespan, reducing the need to increase drive power or frequently replace the lamp due to insufficient brightness, thereby reducing energy consumption and maintenance costs from an overall operating cycle perspective.

[0024] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] The indoor energy-saving lamp provided in this embodiment is used for long-term, stable, and efficient lighting in high-ceiling locations, such as industrial plants, warehousing centers, and large workshops. In this embodiment, by improving the structure of the indoor energy-saving lamp, graded temperature control and heat dissipation are achieved, enabling the indoor energy-saving lamp to emit light efficiently at a stable temperature, extending the life of the lamp beads, and reducing energy consumption and maintenance costs.

[0027] Please see Figures 1-9 The indoor energy-saving lamp provided in this embodiment includes a lampshade 10, a lamp holder 20, an LED 30, a trigger component 40, a cooling component 50, and a heat-conducting component 60. The lamp holder 20 is disposed inside the lampshade 10, the LED 30 is disposed on the lamp holder 20, and the trigger component 40 is disposed on the lamp holder 20 for detecting and feeding back the temperature of the lamp holder 20. The cooling component 50 and the heat-conducting component 60 are electrically connected to the trigger component 40 for reducing the temperature of the lamp holder 20. When the trigger component 40 detects and feeds back the temperature of the lamp holder 20, which is greater than a first preset value and less than a second preset value, the cooling component 50 is activated to cool the lamp holder 20. When the trigger component 40 detects and feeds back the temperature of the lamp holder 20, which is greater than the second preset value, the heat-conducting component 60 is activated to cool the lamp holder 20.

[0028] Specifically, the lamp holder 20 is disposed inside the lamp cover 10 and serves as the mounting carrier for the lamp bead 30 and functional components. The lamp bead 30 is preferably a high-brightness light-emitting diode, which is fixedly mounted on the surface of the lamp holder 20 and electrically connected to an external power supply circuit to achieve stable light emission when powered on. The lamp holder 20 is usually made of a metal or composite material with good thermal conductivity to facilitate the rapid conduction of heat generated by the lamp bead 30 during operation, creating a structural basis for subsequent heat dissipation. The specific connection method between the lamp cover 10 and the lamp holder 20 can adopt common structural forms such as snap-fit, threaded connection, or screw fixing, which are well known to those skilled in the art and will not be described in detail here.

[0029] A trigger component 40 is provided on the lamp holder 20. The trigger component 40 is used to detect the temperature of the lamp holder 20 and output a corresponding temperature feedback signal. It can be specifically selected from structures such as a temperature sensor, a thermistor, or an integrated temperature control module. Preferably, it is directly installed in the area of ​​the lamp holder 20 near the lamp bead 30 to accurately reflect the thermal state of the lamp bead 30 during operation. The trigger component 40 is electrically connected to the cooling component 50 and the heat conduction component 60. When the detected temperature signal reaches a preset condition, the trigger component 40 sends a start signal to the corresponding actuator, thereby realizing the active regulation of the temperature of the lamp holder 20.

[0030] It is understood that the second preset temperature is higher than the first preset temperature. The cooling component 50 is disposed inside the lamp holder 20 or the lamp cover 10, and its function is to provide basic cooling to the lamp holder 20 when the temperature of the lamp holder 20 is between the first and second preset temperatures. The cooling component 50 can be a semiconductor cooling chip, a heat-conducting plate combined with a heat sink fin structure, or a liquid cooling module, etc. The specific structure can be reasonably selected according to the power rating of the lamp and the installation space. The above-mentioned cooling methods are all commonly used technical means in this field. In this embodiment, by activating only the cooling component 50 during the moderate temperature rise stage, the temperature of the lamp holder 20 is controlled in a timely manner.

[0031] A heat-conducting component 60 is disposed within the lamp holder 20 or the lamp cover 10 and is electrically connected to the triggering component 40. Its main function is to enhance heat dissipation when the temperature of the lamp holder 20 exceeds a second preset value. Specifically, the heat-conducting component 60 can be an air-cooled structure with a ducting channel, which accelerates the airflow around the lamp holder 20, improving the efficiency of heat transfer to the external environment. The heat-conducting component 60 works in conjunction with the cooling component 50, enabling the lamp holder 20 to maintain a relatively stable temperature under high-temperature conditions. This structurally avoids sudden temperature rises, component aging, or performance instability caused by localized heat concentration, making it particularly suitable for applications such as high-bay lights that operate continuously for extended periods.

[0032] Through the structural cooperation of the triggering component 40, cooling component 50, and heat-conducting component 60, the lamp holder 20 and the lamp chip 30 always operate within a relatively suitable temperature range. This effectively reduces the decrease in luminous efficiency and the accelerated light decay caused by high temperatures, slows down the performance degradation rate of the lamp chip 30, and thus extends the effective service life of the lamp chip 30. Simultaneously, the stable operating temperature allows the luminaire to maintain high luminous efficiency throughout its entire service life, reducing the need to increase drive power or replace the luminaire prematurely due to brightness reduction. This achieves the technical effects of energy-saving operation and reduced maintenance costs for the luminaire.

[0033] Furthermore, the cooling assembly 50 includes a receiving cavity 510, a coolant 520, and an adjusting member 530. The coolant 520 is disposed within the receiving cavity 510, which includes a first chamber 511, a second chamber 512, and a third chamber 513 connected in sequence. The first chamber 511 and the third chamber 513 are vertically disposed on both sides of the lamp holder 20, while the second chamber 512 is horizontally disposed on the top of the lamp holder 20. A pressure stabilizing hole 514 is provided on the top of the second chamber 512. The adjusting member 530 is communicatively connected to the triggering assembly 40 and is slidably disposed within the first chamber 511 and the third chamber 513 to adjust the position of the coolant 520 within the receiving cavity 510. Specifically, the receiving cavity 510 is preferably fitted to the lamp holder 20 to enhance the heat exchange efficiency between the coolant 520 and the lamp holder 20. The coolant 520 can be a liquid medium with good thermal conductivity and high stability, such as cooling oil, heat transfer fluid or other phase change liquid. The above-mentioned cooling media are well known to those skilled in the art, and their specific composition and selection do not constitute a limitation of this embodiment.

[0034] By placing the first chamber 511 and the third chamber 513 on both sides of the lamp holder 20, the coolant 520 can naturally collect at the bottom of the chambers under gravity. The second chamber 512 is located at the top of the lamp holder 20, allowing the coolant 520 to fully contact the high-heat area of ​​the lamp holder 20 when pushed to this area, thus enhancing the overall cooling effect on the lamp holder 20. The pressure stabilizing hole 514 at the top of the second chamber 512 is used to balance the pressure changes within the receiving cavity 510, preventing overpressure or negative pressure from occurring in the coolant 520 during flow, thereby ensuring the stability of the cooling assembly 50. The structure of the pressure stabilizing hole 514 can be a micropore, a one-way valve, or a breathable membrane structure, all of which are conventional techniques in the field.

[0035] The adjusting member 530 is slidably disposed within the first chamber 511 and the third chamber 513, and is communicatively connected to the triggering component 40. It is used to adjust the position of the coolant 520 within the receiving chamber 510 according to the temperature change of the lamp holder 20. The adjusting member 530 can be a piston-type structure, a floating push plate structure, or a telescopic push rod structure. Its specific driving method can be motor-driven, electromagnetic-driven, or linear actuator-driven. These structures and driving methods are well known to those skilled in the art and will not be described in detail here. By configuring the adjusting member 530 to slide vertically along the chamber, it can change the distribution state of the coolant 520 under different temperature conditions, thereby achieving dynamic adjustment of the cooling capacity.

[0036] When the temperature of the lamp holder 20 is lower than the first preset value, the indoor energy-saving lamp is in the first state. The trigger component 40 controls the adjustment component 530 to be located at the bottom of the first chamber 511 and the third chamber 513. At this time, the coolant 520 is mainly distributed in the first chamber 511 and the third chamber 513, so that the cooling component 50 is in a low-intervention state, which maintains the basic heat exchange between the coolant 520 and the side wall of the lamp holder 20, and avoids excessive cooling that would cause energy waste. When the temperature of the lamp holder 20 rises and exceeds the first preset value but is lower than the second preset value, the indoor energy-saving lamp is in the second state. Under the control of the trigger component 40, the adjustment component 530 moves upward along the first chamber 511 and the third chamber 513, pushing the coolant 520 into the second chamber 512 respectively, so that the coolant 520 is concentrated in the top area of ​​the lamp holder 20, and the lamp holder 20 is cooled more thoroughly, thus improving the cooling intensity from a structural level.

[0037] During the above process, if the temperature of the lamp holder 20 drops below the first preset value due to concentrated heat exchange of the coolant 520, the adjusting component 530 resets to the bottom position of the first chamber 511 and the third chamber 513. Under the action of gravity and the chamber connection structure, the coolant 520 flows back, realizing the automatic return of the cooling component 50 and ensuring that the coolant 520 is always in a better working state. If the temperature of the lamp holder 20 continues to rise and exceeds the second preset value, the indoor energy-saving lamp is in the third state. At this time, based on the continuous operation of the cooling component 50, the heat conduction component 60 is triggered to start, enabling the indoor energy-saving lamp to adjust the distribution and heat dissipation of the coolant 520 according to temperature changes, effectively avoiding heat accumulation, stabilizing the working temperature of the lamp beads 30, reducing the risk of light decay, and ultimately achieving the technical effect of long-term stable operation and energy saving of the lamp.

[0038] Furthermore, the heat-conducting component 60 includes an air guide 610 and a sliding member 620. The air guide 610 covers the outside of the lamp holder 20 and has ventilation holes 611. A sliding channel 515 is formed between the first chamber 511 and the third chamber 513. The air guide 610 is slidably installed in the sliding channel 515 via the sliding member 620, which is communicatively connected to the trigger component 40. Specifically, the air guide 610 covers the outside of the lamp holder 20 and is used to selectively guide external air to exchange heat with the lamp holder 20 under different working conditions. The air guide 610 has a plurality of ventilation holes 611, which can be round holes, strip holes, or mesh structures, to form an air circulation channel when the air guide 610 is exposed. The specific forms of the ventilation holes 611 are all conventional design methods in the art and will not be described in detail.

[0039] When the temperature of the lamp holder 20 is lower than the second preset value, the trigger component 40 controls the sliding component 620 to keep the air guide tube 610 housed in the sliding channel 515. At this time, the air guide tube 610 forms a closed or semi-closed covering structure on the outside of the lamp holder 20, effectively blocking external dust, moisture and other impurities from entering the lamp holder 20, improving the dustproof performance and environmental adaptability of the lamp in daily operation, and avoiding the introduction of excessive cold air under non-high temperature conditions, which would affect the internal temperature stability of the lamp holder 20. When the temperature of the lamp holder 20 rises and exceeds the second preset value, the trigger component 40 drives the sliding member 620 to move along the sliding channel 515, causing the air guide tube 610 to move outward relative to the lamp holder 20 and be exposed. At this time, the ventilation hole 611 on the air guide tube 610 is connected to the external environment, and the external air can directly convect and exchange heat with the surface of the lamp holder 20 through the ventilation hole 611, thereby further improving the heat dissipation efficiency of the lamp holder 20. Through the above structure, the sealing and dustproof performance of the lamp is guaranteed under low temperature or normal temperature conditions, and the air convection channel is opened in time under high temperature conditions to achieve rapid heat dissipation.

[0040] Further, the adjusting member 530 includes a sliding plate 531, a first magnetic element 532, and a second magnetic element 533. The sliding plate 531 slides along the first chamber 511 and the third chamber 513. The first magnetic element 532 is respectively disposed on the bottom surface of the first chamber 511 and the third chamber 513. The second magnetic element 533 is disposed on the side of the sliding plate 531 near the first magnetic element 532. The first magnetic element 532 is an electromagnet. Specifically, the sliding plate 531 can slide vertically along the inner wall of the first chamber 511 and the third chamber 513 to block and push the coolant 520 in the chamber. The sliding plate 531 can be made of a material with good corrosion resistance and temperature resistance. Its external dimensions match the inner diameter of the chamber to ensure good sealing and guiding stability during sliding. The above structural forms are well known to those skilled in the art, and therefore will not be described in detail.

[0041] The first magnetic element 532 is disposed on the inner bottom surface of the first chamber 511 and the third chamber 513, respectively, and is used to generate a controllable magnetic field when the power is switched on or off or when the polarity changes. The second magnetic element 533 is disposed on the side of the slide plate 531 near the first magnetic element 532, and can be a permanent magnet or an electromagnet structure, and is used to form a magnetic attraction or magnetic repulsion force with the first magnetic element 532. By setting the first magnetic element 532 as an electromagnet, its magnetic pole state can be changed under the control of the trigger component 40, thereby achieving precise adjustment of the motion state of the slide plate 531. This magnetic drive method does not require a complex mechanical transmission structure and has the characteristics of fast response speed, compact structure and high reliability.

[0042] When the temperature of the lamp holder 20 is lower than the first preset value, the trigger component 40 controls the first magnetic element 532 to be in a state opposite to the magnetic pole of the second magnetic element 533. At this time, a stable magnetic attraction force is generated between the first magnetic element 532 and the second magnetic element 533, causing the slide plate 531 to be attracted and held at the bottom of the first chamber 511 and the third chamber 513. In this state, the coolant 520 is mainly distributed in the first chamber 511 and the third chamber 513, so that the cooling component 50 is in a basic heat exchange condition, which can maintain the basic heat dissipation requirements of the lamp holder 20 and avoid the coolant 520 from accumulating at the top of the lamp holder 20 and causing unnecessary energy consumption.

[0043] When the temperature of the lamp holder 20 rises and exceeds a first preset value, the triggering component 40 sends a trigger signal to the first magnetic element 532, causing the magnetic poles of the first magnetic element 532 to switch, thereby forming a state of the same pole with the second magnetic element 533, generating a magnetic repulsion force between them. Under the action of this magnetic repulsion force, the sliding plate 531 moves upward along the vertical direction of the first chamber 511 and the third chamber 513, pushing the coolant 520 in the chamber into the second chamber 512 connected to it, so that the coolant 520 is concentrated in the top area of ​​the lamp holder 20, providing rapid and efficient cooling of the lamp holder 20. By directly driving the sliding plate 531 with magnetic force, mechanical friction and structural wear are reduced, making the cooling response more rapid and helping to suppress heat accumulation in the early stage of temperature rise.

[0044] When the concentrated heat exchange of the coolant 520 causes the temperature of the lamp holder 20 to drop again and fall below the first preset value, the trigger component 40 controls the magnetic poles of the first magnetic component 532 to return to their original state, so that the first magnetic component 532 and the second magnetic component 533 re-establish a magnetic attraction state. Under the action of the magnetic attraction, the slide plate 531 automatically resets to the bottom position of the first chamber 511 and the third chamber 513. Under the combined action of gravity and the chamber connection structure, the coolant 520 flows back into the first chamber 511 and the third chamber 513.

[0045] Further, the sliding member 620 includes a slider 621, a third magnetic member 622, and a fourth magnetic member 623. The slider 621 is disposed on both sides of the air guide duct 610 and slides along the sliding channel 515. The third magnetic member 622 is disposed on the bottom surface of the second chamber 512, and the fourth magnetic member 623 is disposed on the side of the slider 621 near the third magnetic member 622. The third magnetic member 622 is an electromagnet. Specifically, the third magnetic member 622, disposed on the bottom surface of the second chamber 512, is an electromagnet structure used to switch the magnetic pole state under the control of the trigger component 40. The fourth magnetic member 623, disposed on the side of the slider 621 near the third magnetic member 622, can be a permanent magnet or an electromagnet, used to form a controllable magnetic attraction or repulsion force with the third magnetic member 622. By setting the third magnetic component 622 as an electromagnet, its magnetic poles can be actively adjusted according to the temperature change of the lamp holder 20, thereby realizing the extension and retraction of the air duct 610 without a complex mechanical drive structure, improving the compactness and reliability of the overall structure.

[0046] When the temperature of the lamp holder 20 is lower than the second preset value, the trigger component 40 controls the third magnetic component 622 and the fourth magnetic component 623 to be in opposite magnetic poles, generating a magnetic attraction between them. This causes the slider 621 and its driven air guide 610 to be attracted and fixed at the top position of the sliding channel 515. At this time, the air guide 610 is in a retracted state, effectively shielding the outside of the lamp holder 20, reducing the entry of external dust, moisture and other impurities into the lamp holder 20, improving the protective performance of the lamp under normal operating conditions, and avoiding unnecessary air convection from affecting the internal temperature stability of the lamp holder 20.

[0047] When the temperature of the lamp holder 20 rises and exceeds the second preset value, the trigger component 40 outputs a trigger signal, causing the magnetic poles of the third magnetic component 622 to change, thus forming a state of the same pole with the fourth magnetic component 623, generating a magnetic repulsion force between them. Under the action of this magnetic repulsion force, the slider 621 slides down along the sliding channel 515, driving the air guide 610 to move to the bottom of the sliding channel 515 and be exposed. At this time, the ventilation hole 611 on the air guide 610 is directly connected to the external environment, and the external air can fully convect and exchange heat with the surface of the lamp holder 20 through the ventilation hole 611, thereby significantly accelerating the heat dissipation speed of the lamp holder 20 and effectively suppressing the accumulation of heat under high temperature conditions.

[0048] When the temperature of the lamp holder 20 decreases under the enhanced heat dissipation effect and falls below the second preset value again, the trigger component 40 controls the third magnetic component 622 and the fourth magnetic component 623 to return to the opposite magnetic pole state, and the magnetic attraction between them is regenerated. The slider 621 moves in the opposite direction along the sliding channel 515 under the action of magnetic force, so that the air guide 610 automatically resets to the top of the sliding channel 515.

[0049] Further, the triggering component 40 includes a mounting base 410, an expansion body 420, a first sensing electrode 430, and a second sensing electrode 440. The mounting base 410 is disposed on the lamp holder 20, the expansion body 420 is disposed inside the mounting base 410, and an electrode plate 421 is disposed on the expansion body 420. The first sensing electrode 430 and the second sensing electrode 440 are disposed on the mounting base 410. When the temperature of the lamp holder 20 is greater than a first preset value and less than a second preset value, the electrode plate 421 is electrically connected to the first sensing electrode 430 to form a first trigger signal. The first trigger signal is used to change the magnetic pole direction of the first magnetic element 532. When the temperature of the lamp holder 20 is greater than the second preset value, the electrode plate 421 is electrically connected to the second sensing electrode 440 to form a second trigger signal. The second trigger signal is used to change the magnetic pole direction of the third magnetic element 622.

[0050] Specifically, the mounting base 410 is fixedly disposed on the lamp holder 20, providing a stable mounting foundation for the trigger component 40 and ensuring good thermal conductivity between it and the lamp holder 20. The mounting base 410 can be made of metal or a high thermal conductivity composite material, so that the heat generated by the lamp holder 20 can be quickly transferred to the expansion body 420. The above structural forms are well known to those skilled in the art and will not be described in detail. The expansion body 420 is disposed within the mounting base 410. It is a structural component sensitive to temperature changes, used to generate volume or length changes after being heated. The expansion body 420 can be made of metal, alloy material, or bimetallic structure with a large coefficient of thermal expansion, or a thermistor element encapsulated with an expansion medium. The above expansion forms are all mature technologies in the art. An electrode plate 421 is disposed on the expansion body 420, used to selectively contact the sensing electrode when the expansion body 420 is displaced, thereby forming a corresponding electrical signal. The first sensing electrode 430 and the second sensing electrode 440 are respectively disposed on the mounting base 410 and are arranged at intervals along the expansion direction of the expansion body 420, so that the electrode sheet 421 can contact it sequentially at different expansion displacement stages.

[0051] When the temperature of the lamp holder 20 is low and below the first preset value, the heat transferred from the lamp holder 20 to the expansion body 420 is insufficient to cause significant deformation. The electrode plate 421 is in its initial position and does not contact the first sensing electrode 430 or the second sensing electrode 440. The triggering component 40 does not output a trigger signal. At this time, the cooling component 50 and the heat-conducting component 60 are both in a basic or standby state, ensuring the stability and low energy consumption of the lamp under normal temperature conditions. When the temperature of the lamp holder 20 rises and exceeds the first preset value but is less than the second preset value, the expansion body 420 deforms due to heat, causing the electrode plate 421 to move outward and form an electrical connection with the first sensing electrode 430, thereby outputting the first trigger signal. The first trigger signal is used to control the change of the magnetic pole direction of the first magnetic element 532, so that the magnetic attraction state between the first magnetic element 532 and the second magnetic element 533 changes to the magnetic repulsion state. The magnetic repulsion force pushes the slide plate 531 to slide upward along the vertical direction of the first chamber 511 and the third chamber 513, pushing the coolant 520 into the second chamber 512, so that the coolant 520 is concentrated on the high temperature area of ​​the lamp holder 20, thereby achieving rapid liquid cooling of the lamp holder 20.

[0052] When the temperature of the lamp holder 20 rises further and exceeds the second preset value, the expansion body 420 undergoes greater displacement under the influence of the higher temperature. The electrode plate 421 continues to move and forms an electrical connection with the second sensing electrode 440, outputting a second trigger signal. The second trigger signal is used to control the change of the magnetic pole direction of the third magnetic element 622, causing the magnetic attraction state between the third magnetic element 622 and the fourth magnetic element 623 to change to a magnetic repulsion state. Under the action of the magnetic repulsion force, the air guide duct 610 slides down along the sliding channel 515 and is exposed, allowing the ventilation holes 611 on the air guide duct 610 to communicate with the external environment. The external air can directly convect and exchange heat with the surface of the lamp holder 20, further improving the heat dissipation efficiency on the basis of liquid cooling.

[0053] Furthermore, a heat-conducting film 516 is provided on the bottom surface of the second chamber 512. The heat-conducting film 516 has an upward-convex arc structure in the middle. Specifically, the heat-conducting film 516 can be made of a high thermal conductivity metal sheet, a composite thermally conductive material, or a ceramic material. Its main function is to improve the heat absorption capacity of the coolant 520 on the lamp holder 20 in the second chamber 512 by increasing the contact area and optimizing the fluid distribution. The upward-convex arc structure design in the middle of the heat-conducting film 516 forms a natural guiding path for the coolant 520 as it flows back from the second chamber 512 to the first chamber 511 and the third chamber 513, thereby ensuring the integrity and continuity of the coolant 520 return flow and avoiding stagnation or uneven dispersion of the coolant 520 during the return flow process.

[0054] In addition, the arc-shaped protrusion structure not only guides the coolant 520 backflow, but also increases the contact area between the heat-conducting film 516 and the surface of the lamp holder 20, improving the heat exchange efficiency and enabling the coolant 520 to absorb the heat of the lamp holder 20 more fully in the second chamber 512, thus achieving rapid cooling.

[0055] Furthermore, slide rails 517 are respectively provided on the end faces of the first chamber 511 and the third chamber 513 that are close to each other, and the slider 621 is slidably installed in the slide rails 517. Specifically, the slide rails 517 can be made of metal or high-strength engineering plastic materials, and their cross-sectional shape can be "T"-shaped, "U"-shaped, or rectangular groove-shaped, so as to fit tightly with the slider 621, achieve smooth sliding and avoid shaking. The above structural forms are well known to those skilled in the art, so they will not be described in detail. The slider 621 is slidably installed in the slide rails 517, so that the air guide tube 610 moves smoothly along the predetermined sliding path under the action of the trigger component 40. This ensures that the air guide tube 610 extends in time to enhance heat dissipation efficiency under high temperature conditions, and also accurately returns to its position after the temperature drops, restoring the protective state of the lamp holder 20. At the same time, the air guide tube 610 can maintain a precise movement trajectory during the sliding process, avoiding jamming or collision of the air guide tube 610 due to guide deviation, thereby preventing obstruction or impact on the lighting effect of the lamp bead 30.

[0056] Furthermore, a rolling element 518 is provided inside the slide rail 517. The rolling element 518 abuts against the slider 621, and the contact surface shape of the slider 621 and the rolling element 518 are matched. Specifically, the rolling element 518 can be a ball, roller, or pulley structure, and its material can be wear-resistant metal or high-polymer engineering plastic to reduce frictional resistance and extend service life. The matching shape of the contact surface shape between the rolling element 518 and the slider 621 allows the air guide 610 to move smoothly along the sliding channel 515 under the drive of the trigger component 40. Whether the air guide 610 extends to dissipate heat under high temperature conditions or returns to its original position after the temperature drops, it can maintain a stable and precise movement path.

[0057] Furthermore, a rubber pad 612 is provided on the top of the air guide 610. Specifically, the rubber pad 612 can be made of silicone rubber, fluororubber, or thermoplastic elastomer material with good elasticity and high temperature resistance. Its main function is to absorb the impact force that may be generated during the sliding process through flexible contact, so as to avoid direct collision between the air guide 610 and the top of the sliding channel 515, thereby reducing noise and wear, and improving the durability of the sliding structure.

[0058] In summary, the indoor energy-saving lamp provided in this embodiment achieves graded temperature control and heat dissipation, enabling the indoor energy-saving lamp to emit light efficiently at a stable temperature, extending the lifespan of the lamp beads by 30 days, and reducing energy consumption and maintenance costs.
