Description

Technical Field

[0001] This invention relates to the field of vehicle lighting technology, specifically to an LED light source module for vehicle front lights. Background Technology

[0002] With the increasing demands for vehicle driving safety and functional diversity, auxiliary front lighting devices (such as front auxiliary lights, fill lights, and work lights) are widely used in nighttime driving, inclement weather lighting, and specific work scenarios. These auxiliary lights are typically installed on the front hood, front grille, or bumper area of ​​the vehicle. Their working environment is complex, requiring them to withstand strong headwinds at high speeds and adapt to various external conditions such as low temperatures, ice, snow, rain, and dust.

[0003] Existing vehicle auxiliary lighting devices generally use high-brightness light source components (such as LED light sources), which generate significant heat during operation. Insufficient heat dissipation can easily lead to an increase in the junction temperature of the light source, resulting in problems such as brightness decay, shortened lifespan, or even failure. Therefore, how to achieve reliable and stable heat dissipation within limited installation space has always been a key focus in this field.

[0004] Currently, the main heat dissipation methods used in existing technologies are as follows: passive heat dissipation,

[0005] For example, natural convection cooling can be achieved through metal casings, heat sinks, or by increasing the heat dissipation area. This method is structurally simple, but its heat dissipation capacity is limited at low wind speeds or when stationary, making it difficult to meet the long-term stable operation requirements of high-power light sources. Forced air cooling methods, such as using fans or relying on the airflow generated by vehicle movement, are also options. However, this method is highly dependent on vehicle speed and external wind conditions, and its cooling effect is unstable at low speeds, idling, or in extremely low temperatures. Furthermore, fan-type electric components suffer from complex structures, reduced reliability, and difficulties in ensuring proper sealing. Sealing and protection are also crucial; to ensure the reliability of auxiliary lights in rain, snow, mud, and dusty environments, the lamp body typically requires a high level of sealing. However, under sealed conditions, internal heat and gases are difficult to expel in a timely manner, further exacerbating the conflict between heat dissipation and protection. Furthermore, in cold or snowy environments, the front of the lamp body and the light-emitting area are prone to freezing, snow accumulation, or condensation due to low temperatures, which can affect the lighting effect. Existing technologies generally lack active anti-icing, anti-snow, and self-cleaning measures for the forward light-emitting area and the rear exhaust area. Therefore, there is an urgent need for a vehicle front auxiliary lighting device that is compact, highly reliable, and capable of adaptively adjusting the lamp body temperature and exhaust state under different operating conditions to overcome the shortcomings of the aforementioned existing technologies.

[0017] The beneficial effects of the LED light source module for vehicle front lights proposed in this invention are as follows:

[0018] 1. The present invention constructs an independent gas passage system within the lamp housing. Through the coordinated arrangement of cold gas passage and hot gas passage, the gas forms a controllable flow path inside the lamp housing. Combined with the first thermosensitive adjustment mechanism, the cold and hot gases are diverted or switched according to the working temperature of the light source component, thereby achieving effective heat dissipation of the light source component and reducing problems such as light decay and shortened lifespan caused by excessive temperature.

[0019] 2. The present invention introduces the second cold branch pipe and the second hot branch pipe into the second buffer chamber through the second thermosensitive adjustment mechanism, and adjusts the ratio of cold and hot gas according to the outside temperature, so that the temperature of the gas discharged through the forward air outlet is kept higher than the ambient temperature, thereby effectively suppressing the frosting and icing phenomenon at the front end of the lamp body in low temperature or snowy environments, and improving driving safety.

[0020] 3. This invention constructs cold air passages and hot air passages within the lamp housing, and coordinates them with a first and a second thermistor to divert, regulate, and mix the gases entering different buffer chambers. This allows the gases to form synergistic air curtain structures on the front and back sides of the lamp housing. Specifically, the temperature-regulated gas in the second buffer chamber is ejected from the front exhaust port, forming a forward air curtain on the side facing the light source emission direction. This continuously cleans and isolates the light-transmitting area at the front of the lamp, reducing the probability of rain, snow, water mist, and dust adhering to the light-transmitting interface and improving lighting stability. Simultaneously, the gas is discharged through the second section of the exhaust pipe and the auxiliary air hole guided by the annular gap at the rear end of the light source assembly, forming a back air curtain on the side of the lamp housing away from the light source emission direction. This allows the spiral airflow formed along the outer periphery of the light source assembly to smoothly exit the lamp housing, continuously cleaning the rear end of the light source assembly and its surrounding gap area. Through the synergistic arrangement of the forward and back air curtains, not only is partitioned protection and self-cleaning of the front and rear ends of the lamp housing achieved, but also...

[0031] 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.

[0032] Please see Figures 1-9 This invention provides a technical solution for a vehicle front light LED light source module. Its detailed connection method is a well-known technology in the field. The working principle and process are mainly described below. The specific work is as follows.

[0033] The vehicle front LED light source module of this embodiment includes a lamp housing 11 and a light source component 2 disposed within the lamp housing 11. The lamp housing 11 is integrally machined or assembled from layers of metal material to simultaneously ensure structural strength, thermal conductivity, and sealing reliability. To accommodate integral machining and facilitate the arrangement of complex air passages, a multi-layer shell stacked and fixed structure is preferred: at least a front shell forming the front mounting interface and light transmission interface, a middle shell forming the main cavity and air passage grooves, and a rear shell forming the back exhaust interface and rear end cover. The shell layers can be connected by screws and positioning structures. The internal working chamber is sealed in rain, snow, water, and dust environments. Through this multi-layer structure, some sections of the gas passage can be sealed by the grooves on the inner wall of the housing and the cover plate, reducing the number of independent pipes and improving the consistency of processing and assembly reliability. A gas regulating device 3 is provided in the lamp housing 11. The gas regulating device 3 has an air inlet and forms a gas passage system in the lamp body. The gas passage system includes a cold gas passage and a hot gas passage. The cold gas passage includes a first cold branch pipe 41 and a second cold branch pipe 51, and the hot gas passage includes a first hot branch pipe 42 and a second hot branch pipe 52.

[0034] In this embodiment, the temperature safety of the light source component 2 is given the highest priority, the anti-adhesion capability of the forward air curtain is given the second priority, and the back exhaust and tail end self-cleaning are given the third priority. The meaning of the above priorities is: when the gas supply capacity is limited or different cavities need gas at the same time, firstly, the gas supply for the circumferential spiral flushing / cooling of the light source component 2 is guaranteed; secondly, the continuous ejection of the forward air curtain and the temperature above the ambient temperature are guaranteed; and finally, the amount of gas for back exhaust and tail end self-cleaning is guaranteed. Through this priority setting, it can be ensured that the reliability of the light source component 2 is still the core under the most unfavorable operating conditions, and light decay or failure due to overheating is avoided. To achieve the above priorities, the gas path design adopts the idea of ​​branch capacity allocation; the first cold branch pipe 41 and the first hot branch pipe The overall air supply capacity of the branch corresponding to 42 is set to be high to support the enhanced working conditions related to the temperature of the light source component 2; the air supply capacity of the branches corresponding to the second cold branch 51 and the second hot branch 52 is set to be stable and adjustable to continuously form a forward air curtain. At the same time, the bridge pipe 61 and the second section of the exhaust pipe 63 serve as the main back exhaust channel and are set to have a large equivalent flow capacity to reduce the back exhaust resistance and stabilize the internal pressure boundary, thereby improving the forward air curtain injection stability in the reverse direction. The first cold branch 41 and the first hot branch 42 are connected to the first thermal adjustment mechanism. The first thermal adjustment mechanism is set inside the lamp housing 11 and includes an adjustment housing 71 that forms a first buffer chamber. The first buffer chamber is used to realize the temporary storage, flow stabilization and path switching of cold and hot gases after they enter.

[0035] More specifically, the first thermal adjustment mechanism includes a first thermal element 72, a threaded push rod 73, a top column 74, an adjustment disc 75, a first vent 76, a second vent 77, a first reset element 78, a first support arm 79, a second reset element 710, and a first rubber plug 711. The first thermal element 72 is arranged on the outside of the adjustment housing 71, and its output end passes through the adjustment housing 71 and extends into the space where the first buffer cavity is located, so that while maintaining the convenience of external assembly, the output end can enter the housing under sealed conditions. The first thermal element 72 preferably senses the temperature of the part thermally coupled with the light source assembly 2, for example... The light source assembly 2 can be thermally connected to the mounting base via a metal thermally conductive connector to ensure that its action threshold can accurately reflect the temperature change of the light source assembly 2. The threaded push rod 73 and the central threaded hole of the adjusting plate 75 form a threaded pair. The threaded push rod 73 moves axially with the output end of the first thermally sensitive element 72, thereby pushing the adjusting plate 75 to rotate, thus realizing the conversion of axial displacement to angular displacement. The first air hole 76 and the second air hole 77 provided on the adjusting plate 75 are used to connect with different passages inside the adjusting housing 71. When the adjusting plate 75 rotates to different positions, the first air hole 76 or the second air hole 77 connects with the corresponding passage. One air vent is connected to the other, while the other is disconnected from the corresponding passage, enabling the selection and switching of the two passages. The top post 74 is positioned at the end of the threaded push rod 73 and moves synchronously with it. The top post 74 abuts against the first support arm 79, causing the first support arm 79 to rotate under the push of the top post 74. The first rubber plug 711 is positioned at the hot air inlet of the hot air passage and connected to the first support arm 79. Thus, while the adjusting disc 75 switches the passage, the first support arm 79 drives the first rubber plug 711 to close or throttle the hot air passage. Through the linkage structure of the adjusting disc 75 switching the passage and the rubber plug closing the hot air, when the light source... When the temperature of component 2 reaches the threshold, the hot air passage is preferentially suppressed, the proportion of cold air increases, and even direct cold air supply is formed. The cooling priority strategy is implemented structurally. The first reset component 78 is set between the regulating housing 71 and the regulating plate 75 to provide the regulating plate 75 with the return force; the second reset component 710 is set between the first support arm 79 and the regulating housing 71 to provide the first support arm 79 with the return force. The two sets of reset components provide reset for the passage switching component and the hot air sealing component respectively, so that the mechanism can reliably return to the initial state after the temperature drops, avoiding passage drift caused by stagnation or intermittent vibration.

[0036] Furthermore, to ensure that the adjustment disc 75 can remain stably stationary at the target gear even under vehicle vibration conditions, this embodiment constructs the adjustment disc 75 with two stable rotational positions. This stabilizing structure is preferably achieved by using a spring ball in conjunction with a positioning hole / positioning groove. Two positioning recesses or positioning grooves are provided on the inner wall of the adjustment housing 71, and a positioning surface that cooperates with them is provided on the outer periphery of the adjustment disc 75. The spring ball is pressed into the corresponding recess under the action of the spring, thereby forming a bite-like stable stationary position at the two positions. This structure can effectively prevent simultaneous leakage of the passage or loss of flow control caused by the adjustment disc 75 being in a half-gear state. The first buffer chamber is connected to the exhaust passage through an internal gas connection structure.

[0037] More specifically, the exhaust passage includes a bridge connector 61, a first exhaust pipe section 62, and a second exhaust pipe section 63. The bridge connector 61 is used to guide the mixed gas in the first buffer chamber to the second exhaust pipe section 63 under normal operating conditions, so that the gas is discharged with less resistance and forms a stable back exhaust boundary. The second exhaust pipe section 63 is disposed inside the lamp housing 11 and communicates with the back exhaust port 15. The back exhaust port 15 is disposed on the side of the lamp housing 11 away from the light source emission direction, and its exhaust direction is opposite to the vehicle's travel direction or forms an angle with the vehicle's travel direction, so that the discharged gas is away from the light-transmitting interface at the front end of the lamp body, and at the same time, the probability of backflow is reduced by the external airflow during driving. The first exhaust pipe section 62 extends along the outer periphery of the light source assembly 2 and is arranged around the light source assembly 2. The first exhaust pipe section 62 is preferably provided with multiple exhaust ports or nozzles. The gas is ejected with a certain circumferential component, forming a spiral flow on the outer wall of the light source component 2. On the one hand, its wall-hugging scouring can improve the heat exchange efficiency of the outer peripheral area of ​​the light source component 2. On the other hand, its circumferential flow is conducive to forming a more uniform circumferential temperature field and reducing local hot spots. An annular gap is formed between the tail end of the light source component 2 and the lamp housing 11. This annular gap serves as a release and guide channel for the spiral airflow, allowing the spiral airflow to circulate and extend towards the tail end. At least one auxiliary air hole 13 is opened on the inner wall of the lamp housing 11 at the position corresponding to the annular gap. The auxiliary air hole 13 is connected to the back outlet 15, allowing the spiral airflow to be discharged to the back outlet 15 through the auxiliary air hole 13. Through this structure, the spiral airflow will not stagnate and swirl in the tail end cavity, thereby reducing turbulent accumulation and internal pressure fluctuations, which is beneficial to the overall air path stability.

[0038] Furthermore, to prevent external moisture, dust, or debris from flowing back into the lamp body through the rear air outlet 15, this embodiment provides one-way valves at the tail end of the second section 63 of the exhaust pipe and the tail end of the auxiliary air hole 13, allowing gas to be discharged only from the inside out. The second cold branch pipe 51 and the second hot branch pipe 52 are connected to the second thermosensitive adjustment mechanism, which is connected to the second buffer chamber 12 inside the lamp body housing 11. The second buffer chamber 12 is connected to the forward air outlet, which is located on the side of the lamp body housing 11 facing the light source emission direction to form a forward air curtain. To ensure that the temperature of the gas ejected from the forward air curtain is always higher than the ambient temperature, this embodiment adjusts the flow ratio of the second cold branch pipe 51 and the second hot branch pipe 52 through the second thermosensitive adjustment mechanism, so that the cold and hot gases entering the second buffer chamber 12 are premixed in the chamber and pressure is equalized before being ejected. 2 is preferably set as an annular or near-annular space so that the gas diffuses uniformly in the circumference and reduces the unevenness of the air curtain caused by local nozzle pressure deviation. In order to further improve the premixing and pressure equalization effect, at least one pressure equalization / rectification structure is preferably set in the second buffer chamber 12, such as: annular distribution plate, perforated rectification plate, labyrinth pressure equalization baffle or flow guide grid. This structure allows the hot and cold gases to undergo diffusion and rectification before entering the nozzle area after entering the second buffer chamber 12, thereby reducing the flow difference between nozzles and improving the continuity and coverage of the forward air curtain. The forward air outlet is preferably arranged in one or more rings of holes in the circumference of the light source assembly 2, and the ejection direction of each hole is set at an angle relative to the emission direction of the light source, so that the jet airflow forms a grazing flow close to the light transmission interface in front, thereby washing and removing rain and snow droplets and dust particles, while avoiding the airflow directly impacting the center of the beam and causing obvious disturbance.

[0039] In a preferred embodiment, the angle between the axis of the forward air outlet and the emission direction of the light source can be set in the range of about 10 degrees to about 45 degrees, and more preferably in the range of about 15 degrees to about 35 degrees. The axis of the hole can also be provided with a certain tangential component in the circumferential direction, so that the air curtain has a circumferential coverage tendency, thereby forming a continuous air curtain. The distribution density of the holes can be determined according to the target air curtain coverage width and air supply capacity. It is preferable to make the hole spacing basically consistent in the circumferential direction to avoid obvious gaps.

[0040] More specifically, the second thermal adjustment mechanism includes a second thermal element 81, an extension push rod 82, a flap 83, a second support arm 84, a third support arm 85, a second rubber stopper 86, a third rubber stopper 87, a third reset element 88, and a fourth reset element 89. The second thermal element 81 is disposed on the outside of the lamp housing 11 to sense the external temperature. Its output end passes through the lamp housing 11 and enters the interior of the second buffer cavity 12. One end of the extension push rod 82 is connected to the output end of the second thermal element 81, and the other end abuts against the flap 83. The flap 83 is rotatably mounted on the cavity wall of the second buffer cavity 12 around a fixed axis. When the second thermal element 81 expands or contracts with changes in ambient temperature, the extension push rod 82 applies force to the flap 83, causing the flap 83 to rotate and form an tilt angle. The second arm 84 and the third arm 85 are respectively arranged on both sides of the flap 83 and rotate synchronously with the flap 83. The second rubber plug 86 is connected to the second arm 84, and the third rubber plug 87 is connected to the third arm 85. The rubber plugs are used to throttle or open / close the corresponding passages of the second cold branch pipe 51 and the second hot branch pipe 52. Since the two arms are linked by the same flap 83, the proportional adjustment of the opening degree of the other side can be realized when the opening degree of one side increases, thus realizing the change of the cold and hot ratio from a structural perspective. The third reset member 88 is set between the second arm 84 and the wall of the lamp housing 11 or the second buffer cavity 12, and the fourth reset member 89 is set between the third arm 85 and the wall of the lamp housing 11 or the second buffer cavity 12. 88 and the fourth reset member 89 respectively provide reset force to their corresponding support arms, so that the flap 83 can return to its initial posture under the action of the support arms and reset members when the output of the thermal element decreases. This ensures that the two rubber plugs return to their original positions synchronously and avoids flow drift caused by the mechanism staying in the middle position. The reset member can be a compression spring, torsion spring, or elastic sheet structure. It is preferred to use an elastic element that is not prone to fatigue failure under vehicle vibration environment. In terms of the forward air curtain nozzle structure, this embodiment can be configured with a graded opening mechanism, which can switch the number of openings under different working conditions. For example, when the forward air outlet is arranged in a circle with a total of 36 holes, the number of openings can be switched through a relatively rotatable annular hole plate: in the first position, only the middle one is opened. Half of the orifices in the orifice distribution achieve a lower flow rate and higher jet velocity air curtain; in the second setting, all orifices are opened to achieve a larger coverage and higher total flow rate air curtain. The above-mentioned setting method can be used to balance the air curtain effect under low and high air supply conditions, avoiding the problems of air curtain breakage and insufficient nozzle jet flow caused by insufficient air supply when it is always fully open. After the setting is switched, the first and second stable positions can also be formed by spring ball positioning or stop structure to ensure that the orifice plate can remain stably in the corresponding setting under vehicle vibration and wind load. At the same time, when the external wind speed decreases or the air supply capacity is insufficient, resulting in insufficient drive, the orifice plate can be returned to the low number of openings setting by the reset component, thereby prioritizing the continuity of the air curtain rather than the number of orifices.

[0041] To achieve a strategy that prioritizes light source cooling, followed by forward air curtain cooling, and then backward exhaust and tail-end self-cleaning, this embodiment preferably arranges the pressure stabilization / equalization function primarily within the second buffer chamber 12, and forms a stable pressure relief boundary through the second section 63 of the exhaust pipe. That is, the second buffer chamber 12 undertakes the pressure equalization and premixing functions of the forward air curtain, and its pressure stability directly determines the consistency of the forward air curtain injection. The second section 63 of the exhaust pipe provides a low-resistance channel for backward exhaust, providing a relatively stable downstream pressure boundary for the system. Simultaneously, the first buffer chamber serves as the gas storage and path switching for the first branch, prioritizing... The first branch is designed to have a more direct and shorter gas path to the first section 62 of the exhaust pipe when enhancing heat dissipation, thereby reducing losses and increasing the effective momentum of the spiral cooling airflow. By prioritizing the short-path cooling capacity of the first branch and the pressure equalization mixing capacity of the second branch in the structure, the priority can be automatically reflected under different operating conditions: when the light source temperature is high, the cooling path is more direct and the hot gas is suppressed; when the ambient temperature is low, the mixing ratio of the forward air curtain is automatically adjusted, and the ejection temperature is higher than the ambient temperature; the back exhaust and the tail auxiliary air hole 13 always maintain unidirectional discharge, achieving stable exhaust and anti-backflow.

[0042] Based on the aforementioned structure of the second buffer chamber 12 and the forward air outlet, this embodiment further includes an adjustment device for achieving graded opening of the forward air outlet. When the vehicle speed is high and the wind speed reaches a preset threshold, the forward air outlet switches from a partially open state (first level) to a fully open state (second level). When the vehicle speed decreases and the wind speed falls below the threshold, the forward air outlet automatically reverts from a fully open state to a partially open state to prioritize the continuity of the forward air curtain and the jet momentum. The adjustment device includes components disposed in the second... Inside the buffer chamber 12, a turntable 91 is rotatable around the central axis of the second buffer chamber 12. An array of holes corresponding to the forward air outlets is formed on the turntable 91. The forward air outlets and the holes on the turntable 91 are axially opposite each other, allowing gas in the second buffer chamber 12 to pass through the holes on the turntable 91 and then re-enter the forward air outlets for ejection. To achieve two-stage switching—one stage opening some holes and the other stage opening all holes—the holes on the turntable 91 preferentially meet the following limitations and design constraints (to ensure uniform air curtain, avoid half-stage leakage, and reduce sudden changes in flow resistance):

[0043] Furthermore, the concentric constraint of the hole positions: the circumferential position of the hole positions on the turntable 91 should be concentrically set with the circumferential position of the forward air outlet, so that when the turntable 91 rotates, the relative offset between the hole positions and the forward air outlet is only manifested as circumferential offset, and does not produce radial misalignment, thereby avoiding the nozzle flow difference caused by local obstruction.

[0044] Orifice matching constraint: The orifice diameter of the turntable 91 is preferably not less than the equivalent flow diameter of the forward exhaust orifice, and can be slightly larger than the forward exhaust orifice diameter to compensate for the additional resistance introduced by the thickness of the turntable 91; at the same time, in order to avoid obvious jet beam distortion when fully open, the axial clearance between the orifice and the forward exhaust orifice should be controlled within a reasonable range so that the airflow can still be effectively oriented by the forward exhaust orifice after passing through the orifice.

[0045] Two-stage alignment constraint: The two stable working positions of the turntable 91 correspond to the holes being fully aligned with the front air outlet and only partially aligned with the front air outlet, respectively. Taking 36 holes in one circle as an example, the first stage can be set to alternate holes for conduction, that is, only 18 holes are aligned; the second stage is that all 36 holes are aligned. In order to avoid irregular coverage in the first stage, it is preferable to adopt a uniform pitch scheme of alternate holes for conduction and one hole for closure, so that the opening holes are evenly distributed in the circumferential direction.

[0046] Sealing surface constraint: An annular sealing interface is preferably provided between the turntable 91 and the front wall of the second buffer chamber 12 or the nozzle base surface, such as a flat contact sealing surface or an annular sealing ring, so that the misaligned hole position is effectively blocked, and gas is prevented from leaking from the non-open hole position, thereby ensuring the jet momentum and air curtain continuity of the 16-hole section.

[0047] Stop and stable position constraint: The turntable 91 should have two stable rotation positions, corresponding to the 16-hole position and the 32-hole position. Preferably, the turntable 91 is stably stopped at the two positions by the combination of the stop structure, the positioning recess and the elastic positioning element, so as to avoid the nozzle flow drift or whistling caused by the half-open and half-closed when it is in the middle position.

[0048] More specifically, the adjustment device includes a connecting shaft 92, the upper end of which is located outside the lamp housing 11, and the lower end extends into the second buffer cavity 12. A wind vane 93 is provided at the upper end of the connecting shaft 92. When the vehicle is moving, the wind vane 93 is subjected to the wind and generates a rotational torque. When the wind speed reaches a preset threshold, the wind vane 93 drives the connecting shaft 92 to undergo angular displacement. The connecting shaft 92 preferably has a damping structure to prevent high-frequency vibration of the connecting shaft 92 under wind speed fluctuations or turbulent pulsations, thereby avoiding air curtain instability caused by frequent switching of the turntable 91. The damping structure can be friction damping, viscous damping, or magnetic damping. Preferably, the damping is set at the mating point between the connecting shaft 92 and the lamp housing 11, for example, by setting a damping sleeve, damping grease, or speed limiting structure in the shaft hole, so that the rotation of the connecting shaft 92 exhibits a slow start and slow stop characteristic. An airbag 95 is set in the second buffer chamber 12, with one end of the airbag 95 fixed to the inner wall of the second buffer chamber 12, and a valve 96 is set at this end. The valve 96 is used to control the gas in the second buffer chamber 12 to enter the airbag 95 or to exit the airbag 95. The lower end of the connecting shaft 92 is linked to the valve 96, so that when the connecting shaft 92 rotates within the range of zero to ninety degrees, the valve 96 switches between the inflation state and the deflation state.

[0049] Furthermore, when the connecting shaft 92 is at its initial angle under low wind speed conditions, the valve 96 is in the exhaust state, allowing the gas inside the airbag 95 to be released or kept at low pressure, thus the airbag 95 is in a contracted state; when the connecting shaft 92 is driven to rotate to a set angle by the wind vane 93 under high wind speed conditions, the valve 96 switches to the inflation state, allowing the gas in the second buffer chamber 12 to enter the airbag 95 and gradually fill the airbag 95. Through this linkage structure, external wind speed triggering can be converted into airbag 95 inflation and deflation control, thereby using the airbag 95 as a force amplification and buffering actuator. The other end of the airbag 95 is connected to the outer wall of the turntable 91, so that the expansion and contraction of the airbag 95 can apply circumferential thrust to the turntable 91, thereby driving the turntable 91 to rotate to achieve hole alignment switching. In order to stabilize the output torque direction of the airbag 95 and avoid force direction drift caused by the bulging of the airbag 95.

[0050] In this embodiment, the airbag 95 is preferably equipped with directional deformation capability. For example, an airbag 95 structure with a restraint jacket, a flat corrugated airbag 95, or an airbag 95 with guide ribs is adopted, so that its expansion mainly outputs displacement in a predetermined tangential direction, while being restricted in the radial or axial direction. Through directional deformation, the inflation process of the airbag 95 can stably push the turntable 91 to switch from the 16-hole position to the 32-hole position, and avoid the deformation of the airbag 95 interfering with other structures in the second buffer cavity 12.

[0051] In a preferred embodiment, the effective stroke of the airbag 95 matches the angular displacement of the turntable 91 at its two positions, so that the displacement of the airbag 95 from contraction to fullness corresponds to the angular displacement of the turntable 91 from the first stable position to the second stable position. The turntable 91 can be stably stopped at the two positions using a stop structure or positioning structure. After the airbag 95 is fully inflated, it maintains a certain internal pressure to provide a holding force to keep the turntable 91 in the second position. A coil spring 94 is provided between the connecting shaft 92 and the lamp housing 11 to provide a restoring force to the connecting shaft 92. When the wind speed decreases, the force on the wind vane 93 decreases, and the connecting shaft 92 returns to its initial angle under the action of the coil spring 94, thereby driving the valve 96 to switch to the exhaust state. The preload of 94 can be set as one of the threshold adjustment methods, so that the wind vane 93 will only overcome the torque of the coil spring 94 and drive the connecting shaft 92 to rotate when the wind speed reaches the set threshold, thereby realizing the mechanized setting of the wind speed threshold. When the connecting shaft 92 is reset to the initial angle, the valve 96 enters the exhaust state, the gas in the airbag 95 is discharged, the airbag 95 gradually contracts, and the turntable 91 returns to the first stable position under the action of the elastic reset structure, thereby realizing the automatic return from the 32-hole position to the 16-hole position. Due to the damping of the connecting shaft 92, frequent back-and-forth switching near the wind speed critical value can be avoided. In order to improve the reliability of the turntable 91's return and avoid the residual pressure of the airbag 95 causing the turntable 91 to stay in the middle position.

[0052] In this embodiment, a spring is installed at the end of the airbag 95 furthest from the valve 96, and the other end of the spring is fixed to the inner wall of the second buffer chamber 12. This spring provides a restoring torque to the turntable 91 when the airbag 95 contracts, enabling the turntable 91 to stably return to the first stable position. It also works in conjunction with the stop or positioning structure of the turntable 91 to ensure a definite return to its position. Simultaneously, the spring also serves as an anti-vibration structure. When the wind speed decreases briefly and the valve 96 begins to exhaust air, the spring's restoring force on the turntable 91 will preferentially cause the turntable 91 to quickly pass through the intermediate unstable zone and enter the first stable position, thereby reducing the duration of the half-open state and preventing intermittent forward air curtain. In the event of a breakage or nozzle whistling, this embodiment achieves purely mechanical wind speed threshold triggering and graded opening of the forward air outlets through the linkage chain of wind vane 93, connecting shaft 92, valve 96, airbag 95, and turntable 91: Under high-speed wind conditions, turntable 91 switches to the fully open position, expanding the coverage and total flow of the forward air curtain; under low-speed or stationary conditions, turntable 91 retracts to the partially open position, concentrating the limited air supply capacity on fewer nozzles, increasing the single-hole jet flow and prioritizing the continuity of the air curtain. Combined with the premixing and pressure equalization structure in the second buffer chamber 12, the uniformity and stability of the forward air curtain under different opening positions can be further improved.

[0053] Working principle: During operation, the gas enters the gas regulating device 3 through the air inlet, and is separated into cold gas and hot gas by the gas regulating device 3, which then enter the cold gas passage and the hot gas passage respectively. The cold gas passage is further divided into a first cold branch pipe 41 and a second cold branch pipe 51, and the hot gas passage is further divided into a first hot branch pipe 42 and a second hot branch pipe 52. The first cold branch pipe 41 and the first hot branch pipe 42 are used for gas path regulation and exhaust / cooling related to the temperature of the light source component 2, and the second cold branch pipe 51 and the second hot branch pipe 52 are used for regulating the temperature of the forward air curtain and for ejection.

[0054] In the gas path related to the temperature of the light source component 2, the first cold branch pipe 41 and the first hot branch pipe 42 enter the first thermal adjustment mechanism and converge into the first buffer chamber. The first thermal adjustment mechanism uses the temperature of the light source component 2 as the trigger quantity. Its thermal element is thermally coupled with the light source component 2, so that the deformation of the thermal element can reflect the true thermal state of the light source component 2. The first thermal adjustment mechanism has at least two path states: when the temperature of the light source component 2 has not reached the threshold, the mechanism is in the normal working position. The gas output from the first cold branch pipe 41 and the first hot branch pipe 42 forms a mixed gas in the first buffer chamber. The mixed gas preferentially enters the second section 63 of the exhaust pipe through the bridge pipe 61 and is finally discharged from the back outlet 15 on the side of the lamp housing 11 away from the light output direction. At this time, the first section 62 of the exhaust pipe maintains low participation or non-participation in the main exhaust, so that the system maintains the stability of the back exhaust and internal pressure boundary with low energy loss, thereby providing a relatively stable gas supply environment for the forward air curtain.

[0055] When the temperature of the light source assembly 2 rises and reaches a threshold, the first thermal adjustment mechanism switches to the enhanced cooling operating position: on the one hand, the mechanism changes the connection relationship of the passage in the first buffer chamber, so that the gas changes from the original path of mainly entering the second section 63 of the exhaust pipe through the bridge pipe 61 to the path of preferentially entering the first section 62 of the exhaust pipe and then flowing into the second section 63 of the exhaust pipe; on the other hand, the mechanism simultaneously restricts or closes the hot gas entry of the hot gas passage, so that the proportion of cold gas output from the first cold branch pipe 41 is significantly increased, and even a state of cold gas dominance or direct cold gas supply is formed; after the cold gas enters the first section 62 of the exhaust pipe, it is ejected from the nozzles arranged circumferentially on the outer wall of the first section 62 of the exhaust pipe. The ejection direction of the nozzles has a circumferential component, so that the ejected cold gas forms a spiral airflow along the outer wall of the light source assembly 2; the spiral airflow is close to the outer periphery of the light source assembly 2. The airflow continuously flushes and heats the outer periphery of the light source component 2, improving heat dissipation efficiency and weakening local hot spots, thereby reducing the risk of light decay caused by temperature rise. The spiral airflow continues to flow along the tail end of the light source component 2, is guided through the annular gap between the tail end of the light source component 2 and the lamp housing 11, and is discharged through the auxiliary air hole 13 provided on the inner wall of the lamp housing 11. At the same time, the tail end of the first section 62 of the exhaust pipe is connected to the second section 63 of the exhaust pipe, and some gas flows into the second section 63 of the exhaust pipe and is discharged from the back outlet 15. One-way valves are provided at the tail end of the second section 63 of the exhaust pipe and the tail end of the auxiliary air hole 13, so that the gas can only be discharged from the inside to the outside, preventing external rain, snow, water vapor, dust or debris from flowing back into the lamp body when the vehicle is driving or parked, thereby maintaining the internal sealing of the lamp body and the cleanliness of the air passage.

[0056] In the air path forming the forward air curtain, the second cold branch pipe 51 and the second hot branch pipe 52 enter the second thermosensitive adjustment mechanism and finally converge into the second buffer chamber 12. The second thermosensitive adjustment mechanism uses the ambient temperature as the trigger value. Its thermosensitive element is set on the outside of the lamp housing 11 to sense the ambient temperature. The output end passes through the lamp housing 11 and enters the second buffer chamber 12, driving the internal flap 83 linkage structure. The flap 83 generates a rotation angle under the output displacement of the thermosensitive element, and synchronously changes the throttling opening of the second cold branch pipe 51 and the second hot branch pipe 52 through the support arms and rubber plug structure on both sides of the flap 83, thereby changing the flow ratio of the two paths entering the second buffer chamber 12. Through this ratio adjustment, the second buffer... The temperature of the mixed gas formed in cavity 12 remains higher than the ambient temperature under different ambient temperatures, thus ensuring that the air curtain ejected from the forward air outlet has a thermal potential difference higher than the environment. This helps to suppress condensation, water accumulation, and frost near the light-transmitting interface, while also improving the ability to remove fine raindrops, snow particles, and dust particles. The hot and cold gases entering the second buffer cavity 12 are premixed and pressure equalized in the cavity before being ejected from the forward air outlet to form a forward air curtain. The forward air outlets are distributed around the light source assembly 2, and the ejection direction is set at an angle relative to the light emission direction, so that the gas covers the space in front of the light emission area in a grazing manner, forming a continuous air curtain barrier, reducing the adhesion and accumulation of rain, snow, water mist, and dust in the light emission area.

[0057] To adapt to the different requirements of air curtain coverage and jet momentum at different vehicle speeds, the forward air outlet is also equipped with a staged opening adjustment device. This allows the forward air curtain to spray with fewer holes at low wind speeds or low vehicle speeds to increase the jet momentum per hole and prioritize the continuity of the air curtain. At high wind speeds or high speeds, it switches to spray with more holes to expand the coverage area and enhance anti-adhesion capability. The core of this adjustment device is a turntable 91 located in the second buffer chamber 12. The turntable 91 has an array of holes corresponding to the forward air outlets. By rotating, the turntable 91 aligns or offsets the holes with the forward air outlets, thereby changing the effective number of open holes. The turntable 91 has two stable working positions. Position: The first position corresponds to fewer holes being open, and the second position corresponds to all holes being open; the switching of the turntable 91 is achieved by a chain that triggers the wind and is executed by the airbag 95: the upper end of the connecting shaft 92 extends out of the lamp housing 11 and is equipped with a wind vane 93. The wind vane 93 generates torque under the action of the wind and drives the connecting shaft 92 to rotate within the range of zero to ninety degrees; a coil spring 94 is set between the connecting shaft 92 and the lamp housing 11 to provide a reset force and form a wind-triggered threshold. The connecting shaft 92 is also equipped with a damping structure to suppress shaking and frequent switching near the critical wind speed; the lower end of the connecting shaft 92 is located in the second buffer chamber 12 and is linked with the valve 96, which is located at one end of the airbag 95. It controls the inflation and deflation between the airbag 95 and the second buffer chamber 12; one end of the airbag 95 is fixed to the inner wall of the second buffer chamber 12, and the other end is connected to the outer wall of the turntable 91. The airbag 95 has directional deformation capability, so that it can apply a stable circumferential driving torque to the turntable 91 when it inflates; when the vehicle speed increases and the wind speed reaches the threshold, the wind vane 93 drives the connecting shaft 92 to rotate, the valve 96 switches to the inflation state, the gas in the second buffer chamber 12 enters the airbag 95, the airbag 95 inflates and pushes the turntable 91 to rotate to the second stable position, so that more holes are opened, and the forward air outlet switches from opening fewer holes to opening more holes; when the vehicle speed decreases and the wind speed reaches the threshold, the airbag 95 controls the inflation and deflation between the airbag 95 and the second buffer chamber 12. When the speed is below the threshold, the connecting shaft 92 is reset under the action of the coil spring 94, the valve 96 switches to the exhaust state, the airbag 95 exhausts and contracts, and the turntable 91 returns to the first stable position under the action of the reset structure, thereby realizing the automatic retraction from opening more holes to opening fewer holes; in order to improve the reliability of retraction and shorten the time that the turntable 91 stays in the middle position, the end of the airbag 95 away from the valve 96 is also connected to a spring, and the other end of the spring is fixed on the inner wall of the second buffer chamber 12. When the airbag 95 contracts, it provides a reset torque to the turntable 91, so that the turntable 91 crosses the middle unstable area and returns to the first position stably, while avoiding uneven air curtain or airflow whistling caused by the half-open state.

[0058] In summary, two synergistic gas functional chains are formed during operation: one is an enhanced cooling and back exhaust chain triggered by the temperature of the light source component 2, which switches between normal exhaust and enhanced cooling through the first thermosensitive adjustment mechanism, and forms a spiral cooling airflow along the outer wall of the light source component 2 during enhanced cooling; the other is a forward air curtain chain triggered by the ambient temperature and vehicle speed wind conditions, which maintains the air curtain temperature higher than the environment through the second thermosensitive adjustment mechanism, and changes the effective number of forward exhaust holes at different vehicle speeds through the wind-triggered graded opening mechanism, thereby ensuring the continuity and momentum of the air curtain at low speeds and expanding the coverage and anti-adhesion effect at high speeds. At the same time, the one-way valve and back exhaust structure suppress backflow and maintain the reliability of the internal sealing of the lamp body.
