Description
Technical Field
[0001] The present invention relates to the technical field of LED vehicle lamps, and in particular to an LED vehicle lamp with high temperature protection. Background Art
[0002] LED headlights have gradually replaced traditional halogen and xenon headlights due to their high efficiency, energy saving and long life. However, LED headlights still face some technical challenges in practical applications, especially in heat dissipation and high temperature protection.
[0003] First, LED light-emitting diodes are very sensitive to heat. Although LED headlights generate less waste heat, high temperatures can cause serious light decay of the LED lamp beads and a sharp drop in brightness, thus affecting the life and performance of the headlights. In order to prevent the impact of high temperatures on the performance of the lamp beads, the prior art usually sets cooling fins on the back of the lamp bead board and installs a cooling fan on the back of the cooling fins to dissipate heat. However, since headlights are usually installed on the inside of the vehicle, close to the engine, when the vehicle is running, the heat generated by the engine will increase the temperature of the air around the headlights, causing the airflow discharged by the cooling fan to be high-temperature airflow, and the heat dissipation effect is extremely poor.
[0004] Secondly, there are usually air holes in the lampshade of the car lights for ventilation and heat dissipation, but in humid weather conditions, water vapor can easily condense into water inside the lampshade, affecting the normal use of the car lights. This not only reduces the heat dissipation efficiency of the car lights, but may also cause circuit short circuits or other faults.
[0005] It can be seen that the heat dissipation and protection measures of existing LED headlights in high temperature and humid environments are still insufficient. It is urgent to propose an LED headlight that can cope with humid environments and has high temperature protection to solve the above problems and improve the service life and performance of the headlights. Summary of the invention
[0006] In order to overcome the above-mentioned shortcomings in the prior art, the present invention provides an LED vehicle lamp that can cope with humid environments and has high temperature protection.
[0007] The technical solution of the present invention is: an LED car lamp with high temperature protection, comprising: A lampshade, in which an LED lamp module is installed, and a ventilation pipe is connected around the rear side of the lampshade; The air guide cover is arranged at the rear side of the lampshade and communicated with the rear end of the LED lamp module. The air guide cover is provided with ventilation slots one adapted to the layout of the ventilation pipe. Each ventilation slot one is connected with a connecting sleeve connected to the adjacent ventilation pipe. The air inlet of the air guide cover is rotatably provided with a filter cartridge for filtering impurities. An electric screw is arranged on the rear side of the air guide cover, and a movable plate is threadedly connected to the electric screw. Assembly frames for installing fans inside are arranged at both ends of the movable plate. Ventilation slots 2 that are compatible with adjacent ventilation slots 1 are provided on the upper and lower sides of the assembly frames, and flow slots for ventilation in humid environments are also provided on the opposite sides of the assembly frames on both sides. A filter is arranged on the rear side of the assembly frame, and two groups of mounting plates that are compatible with the layout of the assembly frames are arranged on the air guide cover. The same group of mounting plates are arranged in an upper and lower interval layout and are slidably connected to the assembly frames on the same side. When the assembly frame approaches and is embedded in the air guide cover, the assembly frames on both sides and the middle part of the air guide cover form a channel suitable for heat dissipation in a humid environment.
[0008] Furthermore, a mounting frame is provided on one side of the air guide cover close to the air inlet, an electric gear is installed in the mounting frame, and a gear ring meshing with a driving gear of the electric gear is provided at the end of the filter cartridge to drive the filter cartridge to rotate.
[0009] Furthermore, a mounting frame is provided between the inner walls on both sides of the air inlet of the air guide hood, and a guide plate extending downward is provided on the mounting frame. The guide plate is located inside the filter cartridge, and a collecting frame located below the filter cartridge is slid at the air inlet of the air guide hood for collecting impurities guided to fall by the guide plate.
[0010] Furthermore, a side panel is provided on each side of the rear of the lampshade, and two partition panels are rotatably arranged between the side panels. The two partition panels are allowed to rotate and close, and a cavity for storing coolant is provided inside the partition panels.
[0011] Furthermore, fan-shaped gears adapted to the assembly frame layout are provided on the inner wall of the partition plate, and a toothed plate is provided on the assembly frame. The upper and lower sides of the toothed plate have gear teeth, and a group of full gears spaced apart from each other are rotated on the side plates on both sides. The full gears are meshed with the adjacent fan-shaped gears and toothed plates on the same side to drive the partition plate to open and close.
[0012] Furthermore, an upper guide plate and a lower guide plate are respectively provided on the upper and lower inner walls of the lampshade, and both the lower guide plate and the upper guide plate are tilted backwards to guide the condensed water inside the lampshade to flow and discharge.
[0013] Furthermore, the bottom of the lampshade is connected to a collecting frame for collecting and draining the accumulated condensed water, and the collecting frame is connected to a drainage pipe.
[0014] Furthermore, a blowing frame with inclined air outlets arranged in a row is arranged on the inner upper wall of the lampshade, and a connecting pipe is connected between the blowing frame and a ventilation pipe thereof.
[0015] The beneficial effects are: 1. The present invention realizes the effective circulation of airflow inside the lampshade through the coordinated work of the ventilation duct, the air guide cover and the assembly frame, which can quickly dissipate the heat generated by the operation of the LED lamp module, and automatically switch the heat dissipation mode according to the environmental conditions (dry or humid): in a dry environment, the above-mentioned components are used to achieve heat dissipation with the help of external natural wind flow; in a humid environment, an independent flow channel is constructed through the assembly frame and the air guide cover, and the dry air in the car is used as a cooling medium to effectively prevent the formation of condensed water. This dynamically adjusted heat dissipation method is not only easy to operate, but also efficient and reliable.
[0016] 2. The present invention forms a physical barrier by providing an openable and closable partition plate, which effectively isolates the influence of high temperature in the car on the LED lamp module. At the same time, coolant is stored in the internal cavity of the partition plate to further block the heat transfer from heat sources such as the engine in the car, significantly reducing the risk of light decay of the lamp beads due to high temperature.
[0017] 3. The present invention can guide and discharge condensed water in time by designing upper and lower drainage plates and combining a collection frame with a drainage pipe, thereby avoiding short circuit or other faults caused by water retention, thereby ensuring the safety and stability of the equipment.

[0032] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0033] In addition, the terms "first", "second" and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0034] Embodiment: A LED lamp with high temperature protection, such as Figure 1-Figure 7 and Fig.13 As shown, including: The lampshade 1 is the main shell of the entire headlight and is used to install and protect the internal components. An LED lamp module 11 is installed inside the lampshade 1 as the core light-emitting component of the headlight. A ventilation pipe 12 is connected to the rear side of the lampshade 1 to introduce external airflow to achieve heat dissipation. The air guide cover 2 is arranged at the rear side of the lampshade 1 and communicated with the rear end of the LED lamp module 11. The interior of the air guide cover 2 is a hollow structure and air outlets are provided at both left and right ends to guide the flow of air. A ventilation slot 211 adapted to the layout of the ventilation pipe 12 is provided on the air guide cover 2. Each ventilation slot 211 is connected with a connecting sleeve 21 connected to the adjacent ventilation pipe 12. The air inlet of the air guide cover 2 is rotatably provided with a filter cartridge 24 for filtering impurities. It can be seen from the above that through the combination of the air guide cover 2 and the lampshade 1, the air guide cover 2 is used as a flow channel, and the air outlet is used to guide the external air flow to enter, so that the external air flow is used as a cooling medium. With the help of the flow of air, it passes through the air guide cover 2, the ventilation slot 211, the connecting sleeve 21, the lampshade 1 and the LED lamp module 11 in turn, fully covering all components and taking away heat, achieving efficient heat dissipation effect, providing necessary high-temperature protection for the car lamp, and ensuring its safety in use and performance stability. The electric screw 3 is fixedly arranged in the middle position of the rear part of the air guide cover 2. A movable plate 32 is threadedly connected to the electric screw 3. The connected movable plate 32 is driven by the electric screw 3 to move linearly in the front-rear direction. Assembly frames 33 with internally mounted fans 35 are arranged at both left and right ends of the movable plate 32. Ventilation slots 331 matching the adjacent ventilation slots 211 are provided on the upper and lower sides of the assembly frames 33 to facilitate subsequent alignment operations. Flow slots 332 for ventilation in humid environments are also provided on the opposite sides of the assembly frames 33. The flow slots 332 are rectangular slot-shaped structures. A filter screen 34 is arranged on the rear side of the assembly frame 33 to block impurities and dust in the flowing airflow. Two groups of mounting plates 31 matching the layout of the assembly frames 33 are also arranged on the air guide cover 2. The number of mounting plates 31 in each group is two. The two mounting plates 31 in the same group are arranged with an upper and lower spacing and form a sliding connection with the assembly frame 33 on the same side. See for details. Figure 4 The mounting plates 31 are provided with slide grooves extending in the front-rear direction, and the upper and lower sides of the assembly frame 33 on the same side are provided with protruding ends, which are slidably embedded in the slide grooves of the adjacent mounting plates 31 on the same side, thereby forming a sliding connection between the mounting plate 31 and the assembly frame 33, and then with the driving action of the electric screw 3, the assembly frame 33 and the components thereon can move in coordination with the moving plate 32, and move synchronously in the front-rear direction, that is, approach or move away from the air guide cover 2.
[0035] Specifically, through grooves that match the size and position of the assembly frame 33 are provided on both sides of the rear of the air scoop 2. When the assembly frame 33 approaches the air scoop 2, it will gradually pass through the corresponding through grooves and embed into the interior of the air scoop 2, so that the ventilation groove 2 331 is aligned and connected with the ventilation groove 1 211. Since the back surfaces of the two sides of the assembly frame 33 are in a closed state, the air outlets on both sides of the air scoop 2 can be effectively blocked, thereby cutting off the direct connection between the inside and the outside. At the same time, through the guidance of the flow groove 332, the assembly frame 33 and the middle section of the air scoop 2 form an independent air flow channel. Under this structure, the fans 35 on both sides can achieve efficient heat dissipation through the exhaust effect, using the dry air in the car as the cooling medium, so that the cooling air can flow from the following paths: 1. Passing through the assembly frame 33 and the second ventilation slot 331, it enters the lampshade 1 and the LED lamp module 11, and finally exits from the assembly frame 33 on the other side; 2. Alternatively, the light flows from the assembly frame 33 and the flow groove 332 to the air guide cover 2 to cover the rear end of the LED lamp module 11 and is finally discharged from the assembly frame 33 on the other side.
[0036] It can be seen that this structural design is particularly suitable for use in humid weather. The heat dissipation function can be dynamically adjusted according to environmental conditions, thereby significantly reducing the condensation effect caused by temperature difference and effectively preventing the generation of condensed water inside the lampshade 1. It not only maintains a good heat dissipation effect, but also minimizes the potential damage to the car lights, allowing the car lights to flexibly cope with the heat dissipation operation in different environments.
[0037] like Figure 4-Figure 6 As shown, a mounting frame 22 is provided on one side of the air guide cover 2 close to the air inlet, an electric gear 221 is installed in the mounting frame 22, and a gear ring 241 meshing with the driving gear of the electric gear 221 is provided at the end of the filter cartridge 24 to drive the filter cartridge 24 to rotate.
[0038] like Figure 5 and Figure 6 As shown, a mounting frame 23 is provided between the inner walls on the left and right sides of the air inlet of the air guide cover 2, and a guide plate 231 extending downward is provided on the mounting frame 23. The guide plate 231 is located inside the filter cartridge 24, and a collecting frame 25 located below the filter cartridge 24 is slid at the air inlet of the air guide cover 2 for collecting impurities guided to fall by the guide plate 231.
[0039] Specifically, see Figure 6As shown, as the filter cartridge 24 rotates, its outer wall will fit closely with the inner wall of the air guide hood 2. When the airflow enters the air guide hood 2, due to the blocking effect of the guide plate 231, the airflow will be guided to flow downward in the direction of the guide plate 231. Under the influence of the pressure difference, the downward airflow becomes stronger, thereby effectively impacting the filter cartridge 24, causing the impurities and dust attached thereto to fall off. At the same time, the continuous rotation of the filter cartridge 24 causes its surface to produce a scraping effect with the upper and lower inner walls of the air guide hood 2, further helping to remove impurities. The impurities that fall off then fall into the collection frame 25 below, realizing the functions of scraping and collecting. This design can effectively improve the cleaning efficiency of the filter cartridge 24 and ensure the orderly collection of impurities.
[0040] like Figure 1 , Figure 8 , Fig. 9 and Fig.13 As shown, a side panel 4 is provided on each of the left and right sides of the rear of the lampshade 1, and two partition panels 41 are rotatably arranged between the side panels 4 on both sides. The two partition panels 41 are allowed to rotate and close, and the partition panels 41 have cavities for storing coolant inside. The partition panels 41 can be opened and closed according to different heat dissipation environment requirements. When dissipating heat in a dry environment, the partition panels 41 are closed. At this time, the coolant stored in the cavity inside can effectively ensure the heat dissipation effect of the headlights, while blocking the flow between the heat flow in the car and the headlights to avoid heat interference. When dissipating heat in a humid environment, the partition panels 41 need to be opened to ensure that the dry air in the car can form a good flow with the headlights, so as to better utilize the dry air to meet the heat dissipation requirements of the headlights, reduce the generation of condensed water and optimize the heat dissipation performance.
[0041] like Figure 8 , Fig. 9 and Fig.13 As shown, the inner wall of the partition plate 41 is provided with a sector gear 42 adapted to the layout of the assembly frame 33. Specifically, in this embodiment, the sector gear 42 is a quarter gear, and a toothed plate 44 is provided on the assembly frame 33. The upper and lower sides of the toothed plate 44 have gear teeth. A group of full gears 43 spaced apart from each other are rotated on the side plates 4 on both sides. The full gear 43 is meshed with the adjacent sector gear 42 and the toothed plate 44 on the same side to drive the partition plate 41 to open and close.
[0042] like Fig.10 and Fig.11 As shown, the upper and lower inner walls of the lampshade 1 are respectively provided with an upper guide plate 51 and a lower guide plate 5, and the lower guide plate 5 and the upper guide plate 51 are both tilted backwards. This structure can effectively guide the condensed water attached to the upper and lower walls inside the lampshade 1, and can flow along the upper guide plate 51 and the lower guide plate 5 respectively, and finally be discharged smoothly, thereby avoiding the accumulation of condensed water inside the lampshade 1 and ensuring the normal operation and service life of the car lamp.
[0043] like Fig.10 and Fig.11 As shown, the bottom of the lampshade 1 is connected to a collecting frame 52 for collecting and accommodating condensed water drained from the inner wall of the lampshade. The collecting frame 52 is connected to a drainage pipe 53, through which the collected condensed water can be further guided to the outside, thereby ensuring the orderly discharge of the condensed water and effectively preventing moisture from accumulating inside the lampshade 1.
[0044] like Figure 10-12 As shown, the upper inner wall of the lampshade 1 is provided with a blowing frame 6 with inclined air outlets arranged therein, and the inclined air outlets can be used to guide the direction of the airflow. A connecting pipe 61 is connected between the blowing frame 6 and a ventilation pipe 12 thereof, which can optimize the air circulation in the lampshade 1 and effectively improve the heat dissipation efficiency.
[0045] When used in a dry environment, it is necessary to ensure that the air guide cover 2 maintains good circulation with the outside air, and close the partitions 41 on both sides. At this time, the partition 41 is connected to the internal cooling system of the car, and the cavity of the partition 41 is filled with coolant. By forming a barrier by itself, the lampshade 1 and its components are protected to prevent the heat flow in the car from affecting the operation and heat dissipation performance of the LED lamp module 11. At the same time, as the car drives, the outside airflow enters through the air inlet of the air guide cover 2. During this process, the electric gear 221 is started, driving the driving gear connected thereto to mesh with the gear ring 241, driving the filter cartridge 24 to rotate. When the airflow passes through the rotating filter cartridge 24, impurities and dust are blocked and retained by the filter holes of the filter cartridge 24. As the filter cartridge 24 rotates and under the guidance of the guide plate 231, the impurities attached to the filter cartridge 24 are blown by the wind flow and scraped by the inner wall of the air guide cover 2, and finally fall into the concentration frame 25 below. Subsequently, the circulating airflow passes through the LED lamp module 11 as a cooling medium, and enters the interior of the lampshade 1 through the ventilation pipe 12, taking away the heat generated by the LED lamp module 11 during operation, thereby achieving effective heat dissipation.
[0046] When used in a humid environment, in order to prevent the occurrence of condensation, it is necessary to start the electric screw 3, push the moving plate 32 to move closer to the wind guide cover 2, and the components at both ends of the moving plate 32 move synchronously. The assembly frame 33 slides along the mounting plate 31 until it is completely embedded in the wind guide cover 2, so that the ventilation slot 2 331 is aligned and connected with the ventilation slot 1 211, so that the air outlets on both sides of the wind guide cover 2 can be closed through the assembly frame 33. At the same time, the movement of the assembly frame 33 synchronously drives the connected toothed plate 44 to move, so that it meshes with the full gear 43 and drives the full gear 43 to rotate. The full gear 43 further meshes with the fan gear 42, driving the partition plate 41 to rotate and open, so that the lampshade 1 is connected with the car. At this time, the fans 35 on both sides are started, and the fan 35 on one side extracts dry air in the car as a heat dissipation medium. The airflow passes through the filter 34 of the assembly frame 33 and the flow groove 332 into the wind guide cover 2, and then is discharged by the fan 35 on the other side. The heat dissipation is completed with the help of the dry air in the car, avoiding the problem of condensation caused by the entry of humid cold air. In addition, part of the airflow enters the lampshade 1 through the second ventilation slot 331, and part of it is introduced into the blowing frame 6 through the connecting pipe 61, and blows to the LED lamp module 11 over a large range through the inclined air outlet, ensuring a stable and efficient heat dissipation process.
