Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, and in particular to a vehicle lighting and vehicle. Background Technology

[0002] Currently, in cold or humid weather conditions, fog or even water droplets can easily appear on the inner wall of the headlight cover, which may mislead users into thinking that water has entered the headlight. Moreover, fog or water droplets can also obstruct the light, affecting the lighting effect of the light source components and thus affecting driving safety. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a vehicle headlight and a vehicle, wherein the headlight cover has a transparent portion. By placing a heating component on the lower side of the transparent portion, the airflow heated by the heating component can flow along the inner wall of the transparent portion, thereby removing water droplets and fog on the inner wall of the transparent portion, making the light passing through the transparent portion less susceptible to interference from water droplets and fog.

[0004] According to a first aspect of the present invention, a vehicle lamp includes: a lamp housing, a lamp cover, a light source assembly, and a heating assembly. The lamp housing and the lamp cover are fitted together along a first horizontal direction to jointly define a mounting cavity. The mounting cavity includes a first chamber and a second chamber that are connected and disposed together. The first chamber is located above the second chamber. The lamp cover has a transparent portion that is disposed corresponding to the first chamber. The light source assembly is disposed in the first chamber, and the light source assembly and the lamp cover are fitted together to form an airflow channel that is connected to the second chamber and extends toward the lower end of the transparent portion. The heating assembly is disposed in the second chamber and is located below the transparent portion. The heating assembly is disposed adjacent to the transparent portion in the first horizontal direction.

[0005] According to an embodiment of the present invention, the transparent portion of the lamp cover is disposed corresponding to the first chamber, and the light source assembly is disposed in the first chamber so that the light emitted by the light source assembly can pass through the transparent portion. The light source assembly and the lamp cover cooperate to form an airflow channel, which connects the first chamber and the second chamber. The airflow channel extends toward the lower end of the transparent portion, and the heating assembly is disposed in the second chamber and located on the lower side of the transparent portion. When the vehicle lamp is placed in a cold or humid environment, there may be fog or water droplets on the inner wall surface of the transparent portion. At this time, the airflow heated by the heating assembly can pass through the airflow channel from the second chamber to the first chamber, so that the heated air can flow along the inner wall surface of the transparent portion, thereby effectively removing the water droplets and fog that may exist on the inner wall surface of the transparent portion. This makes the light passing through the transparent portion less susceptible to interference from water droplets and fog, and facilitates the improvement of the stability of the vehicle lamp operation.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0033] Hereinafter, with reference to the accompanying drawings, a vehicle light 100 according to a first aspect embodiment of the present invention will be described.

[0034] like Figure 1 and Figure 2 As shown, the vehicle lamp 100 includes: a lamp housing 1, a lamp cover 2, a light source assembly 3, and a heating assembly 4. The lamp housing 1 and the lamp cover 2 are fitted together along a first horizontal direction to jointly define a mounting cavity 10. The mounting cavity 10 includes a first chamber 10a and a second chamber 10b that are connected in communication. The first chamber 10a is located above the second chamber 10b. The lamp cover 2 has a transparent portion 20, which is disposed corresponding to the first chamber 10a. The light source assembly 3 is disposed in the first chamber 10a, so at least a portion of the light source assembly 3 is located within the first chamber 10a.

[0035] As can be seen, the lamp housing 1 and the lamp shade 2 are fitted together along the first horizontal direction to jointly define the mounting cavity 10. For example, the lamp shade 2 is inserted into the lamp housing 1 along the first horizontal direction, and the mating parts of the lamp housing 1 and the lamp shade 2 are fixed by applying glue, so that the lamp shade 2 and the lamp housing 1 define a relatively sealed mounting cavity 10. The light source assembly 3 and the heating assembly 4 are located inside the mounting cavity 10, and external impurities are not easily allowed to enter the mounting cavity 10, which helps to improve the working stability of the light source assembly 3 and the heating assembly 4. The mounting cavity 10 includes a first chamber 10a and a second chamber 10b that are connected. The transparent part 20 of the lamp shade 2 is set in the first chamber 10a. The light source assembly 3 is also set in the first chamber 10a, and the heating assembly 4 is set in the second chamber 10b, so that the light emitted by the light source assembly 3 can be emitted through the transparent part 20, making the operation of the light source assembly 3 less susceptible to interference from other parts of the lamp shade 2 and the heating assembly 4, which helps to improve the working stability of the light source assembly 3.

[0036] The light source assembly 3 and the lamp cover 2 cooperate to form an airflow channel 22. For example, the assembly gap between the light source assembly 3 and the lamp cover 2 during assembly defines the airflow channel 22, or there is a pre-set empty space between the light source assembly 3 and the lamp cover 2 to define the airflow channel 22, or there is an assembly gap between multiple components of the light source assembly 3 to define the airflow channel 22.

[0037] For example, the light source assembly 3 includes a light source component, an optical element, and a bracket. The bracket supports the light source component and the optical element. The light emitted from the light source component can pass through the optical element and then through the transparent portion 20 of the lamp cover 2. The airflow channel 22 can be defined by the gap between the light source assembly 3 and the lamp cover 2, or by the gap between the light source component, the optical element, and the bracket. Therefore, the airflow channel 22 does not occupy a large space within the mounting cavity 10. Workers can reasonably select the specific configuration of the airflow channel 22 according to the actual installation situation, which facilitates the adaptability of the airflow channel 22 and also helps to achieve the miniaturization design of the vehicle lamp 100.

[0038] Furthermore, the airflow channel 22 is connected to the second chamber 10b, which in turn connects the first chamber 10a and the second chamber 10b. The airflow channel 22 extends toward the lower end of the transparent portion 20. The heating component 4 is located in the second chamber 10b and below the transparent portion 20. The airflow heated by the heating component 4 can flow from the second chamber 10b to the first chamber 10a and toward the lower end of the transparent portion 20 through the airflow channel 22 (for example, the end of the airflow channel 22 away from the transparent portion 20 can extend to the location of the heating component 4). Utilizing the upward trend of hot air, the heated airflow can spontaneously flow from the lower side of the transparent portion 20 to the upper side of the transparent portion 20. That is, the heated airflow can flow from bottom to top along the inner wall of the transparent portion 20, thereby effectively removing water droplets and fog that may exist on the inner wall of the transparent portion 20. This makes the light passing through the transparent portion 20 less susceptible to interference from water droplets and fog, thus improving the stability of the vehicle headlight 100 operation.

[0039] For example, when the headlight 100 is placed in a cold or humid environment, there may be fog or water droplets on the inner wall of the transparent part 20. At this time, the airflow heated by the heating component 4 can be transmitted from the second chamber 10b to the first chamber 10a through the airflow channel 22, so that the heated air can flow along the inner wall of the transparent part 20, thereby effectively removing the water droplets and fog that may exist on the inner wall of the transparent part 20, so that the light passing through the transparent part 20 is not easily interfered with by water droplets and fog, which helps to improve the stability of the headlight 100 operation.

[0040] In this configuration, the heating component 4 is positioned adjacent to the transparent portion 20 in the first horizontal direction. For example, the lamp cover 2 is fitted to the front side of the lamp housing 1 in the first horizontal direction. In this first horizontal direction, the distance between the heating component 4 and the transparent portion 20 is less than the distance between the heating component 4 and the rear end of the lamp housing 1. This closer proximity allows the airflow heated by the heating component 4 to more promptly and smoothly contact the transparent portion 20, resulting in a clearer airflow path. This improves the efficiency of the vehicle lamp 100 in removing fog and water droplets, and enhances the stability of the vehicle lamp 100's operation. It can be understood that the heating component 4 can increase the dew point of the air inside the mounting cavity 10 through heating, thereby reducing the humidity saturation in the air and improving the fog and water droplet problem inside the mounting cavity 10.

[0041] Furthermore, the heating component 4 has a relatively long service life, making it easy to ensure that the service life of the heating component 4 and the headlight 100 are roughly the same. Related technologies use disposable desiccants to reduce humidity in the mounting cavity, thereby reducing fogging. However, disposable desiccants cannot be replaced, and their service life is short; they typically fail after two years of use, which is detrimental to subsequent headlight use. Alternatively, replaceable desiccants can be used to reduce fogging, but replaceable desiccants are bulky, expensive, and require regular replacement, increasing the maintenance cost of the headlight. Additionally, it is necessary to design... The requirement to reserve space for maintenance operations during the timing process imposes significant constraints and difficulties on the design and spatial layout of vehicle lighting products. However, according to the embodiment of the present invention, the heating component 4 of the vehicle lighting 100 has a lower cost and is easier to ensure that the service life of the heating component 4 and the vehicle lighting 100 is roughly the same. Compared with the replacement desiccant solution, the setting of the heating component 4 does not require reserving space for maintenance operations, or does not require reserving a large space for maintenance operations, which facilitates long-term defogging and helps to reduce the constraints imposed by the setting of the defogging function on the layout and product design of various components within the vehicle lighting 100.

[0042] Optionally, the heating component 4 is a flexible heating element, such as a graphene heating element, an electric heating element, or a resistance heating element; or, the heating component 4 is a non-flexible heater, such as a ceramic heater or a metal tube heater. In this embodiment, there are no specific limitations on the structure or material of the heating component 4, as long as the heating component 4 can heat the surrounding environment.

[0043] It is understandable that flexible heating elements have the advantages of being thin, easy to install, adaptable to complex shapes and irregular spaces, and can be used in scenarios that require close contact with complex walls (such as installation on the inner surface of the lampshade 2 or the inner surface of the lamp housing 1). In contrast, non-flexible heaters, such as ceramic heaters and metal tube heaters, are more suitable for situations with extremely high requirements for heating stability or harsh working environments due to their high temperature resistance, resistance to mechanical vibration, and long service life. Operators can choose between these two similar heating components 4 according to the specific design requirements and working environment of the vehicle light 100, which can improve the flexibility of the heating component 4.

[0044] like Figure 1As shown, in some embodiments, the heating component 4 is disposed on the inner surface of the second chamber 10b, for example, the heating component 4 is bonded to the inner surface of the second chamber 10b, so that the heating component 4 can make fuller use of the space of the second chamber 10b. The heating component 4 does not occupy a large space in the second chamber 10b, so the second chamber 10b does not need to be designed to be too large, and the heating component 4 is less likely to affect the space of the first chamber 10a, providing more space for the arrangement of the light source component 3 and facilitating the assembly of the light source component 3; and / or, the heating component 4 includes at least one flexible heating sheet, such as a graphene heating sheet, an electric heating sheet, a resistance heating sheet, etc. The flexible heating sheet has good flexibility and plasticity, and can adapt to the design of vehicle lamps 100 of different shapes and sizes, enhancing the versatility and applicability of the heating component 4. At the same time, the flexible heating sheet is usually thinner and lighter, so that the heating component 4 does not occupy a large space, facilitating the installation of the heating component 4 and the layout of the vehicle lamp 100. It is understood that the heating component 4 may include a flexible heating element or multiple flexible heating elements to further improve the heating efficiency of the heating component 4; of course, the heating component 4 may also be configured to include flexible heating elements and non-flexible heaters.

[0045] like Figure 1 As shown, in some embodiments, the lampshade 2 further includes a connecting portion 21, which surrounds the transparent portion 20 and engages between the transparent portion 20 and the lamp housing 1.

[0046] As can be seen, the connecting part 21 is fitted between the transparent part 20 and the lamp housing 1, so the lampshade 2 can be fitted to the lamp housing 1 through the connecting part 21. For example, the transparent part 20 and the connecting part 21 of the lampshade 2 are fixedly set, and the mounting cavity 10 is defined by inserting the connecting part 21 of the lampshade 2 into the lamp housing 1.

[0047] The lower part of the connecting portion 21 is recessed downward to define a portion of the second chamber 10b. The heating component 4 is disposed in the second chamber 10b, so the heating component 4 can correspond to the area of ​​the lower part of the connecting portion 21 that is recessed downward. By recessing the lower part of the connecting portion 21, the space of the second chamber 10b is made larger, making the placement of the heating component 4 more flexible. At the same time, the lower part of the connecting portion 21 is recessed downward, which makes the overall space of the lamp cover 2 larger, providing more operating space for the installation of the light source component 3 and the heating component 4, thus making the assembly of the vehicle lamp 100 simpler.

[0048] For example, one end of the lamp housing 1 is open in the first horizontal direction to form a mounting opening, and the lamp cover 2 is covered in the mounting opening along the first horizontal direction. The connecting portion 21 of the lamp cover 2 is recessed downward along the height direction of the vehicle lamp 100 so that the size of the lamp cover 2 in the height direction of the vehicle lamp 100 is larger. Therefore, the mounting opening that mates with the lamp cover 2 can also be larger in the height direction of the vehicle lamp 100, providing more operating space for the installation of the light source assembly 3 and the heating assembly 4, and facilitating the improvement of the assembly efficiency of the vehicle lamp 100.

[0049] like Figure 1 As shown, in some embodiments, the connecting portion 21 helps to define the airflow channel 22, and the airflow channel 22 can be disposed between the connecting portion 21 and the light source assembly 3; the heating assembly 4 includes at least one of a first heating element 40, a second heating element 41 and a third heating element 42. The first heating element 40 is disposed on the side wall of the connecting portion 21 in the first horizontal direction, or in other words, the first heating element 40 is disposed on the side wall of the connecting portion 21 opposite to the lamp housing 1 in the first horizontal direction. The second heating element 41 is disposed on the bottom wall of the connecting portion 21, and the third heating element 42 is disposed on the bottom wall of the lamp housing 1, and the third heating element 42 is disposed adjacent to the connecting portion 21.

[0050] As can be seen, the airflow channel 22 is positioned towards the lower end of the transparent portion 20, and the connecting portion 21 helps to define the airflow channel 22. Therefore, the airflow channel 22 extends at least partially in the vertical direction. The connecting portion 21 surrounds the transparent portion 20, and its lower part is recessed downwards to define a portion of the second chamber 10b. For example, the recessed portion of the connecting portion 21 includes a side wall and a bottom wall, which are configured in an "L" shape. By placing the first heating element 40 on the side wall of the connecting portion 21, the first heating element 40 is positioned closer to the transparent portion 20 in the vertical direction, shortening the airflow path. This reduces the likelihood of significant airflow loss after heating, allowing the airflow heated by the first heating element 40 to contact the transparent portion 20 more quickly, thus improving fog removal. The heating assembly 4 includes at least one of the following components: a first heating element 40, a second heating element 41, and a third heating element 42. The first heating element 40 can make fuller use of the space in the first horizontal direction of the headlight 100, making the structure of the headlight 100 more compact and facilitating miniaturization. The second heating element 41 is positioned on the bottom wall of the connecting portion 21, minimizing its impact on the vertical component arrangement of the headlight 100 and improving assembly efficiency. It also minimizes the impact on airflow within the airflow channel 22, enhancing the stability of the headlight 100's operation. The third heating element 42 is positioned on the bottom wall of the headlight housing 1, adjacent to the connecting portion 21, allowing the heated airflow to smoothly pass through the airflow channel 22 and contact the transparent portion 20. Therefore, the heating assembly 4 includes at least one of the first heating element 40, the second heating element 41, and the third heating element 42, making its placement more flexible and adaptable to different installation conditions.

[0051] Furthermore, since the connecting portion 21 participates in defining the airflow channel 22, and the arrangement of the first heating element 40, the second heating element 41 and the third heating element 42 are all adjacent to the connecting portion 21, it is convenient for the heating assembly 4 to be set near the airflow channel 22, and the surrounding air heated by the heating assembly 4 can flow to the lampshade 2 in a timely manner through the airflow channel 22.

[0052] It is understood that the heating component 4 may include one of the first heating element 40, the second heating element 41, and the third heating element 42, or the heating component 4 may include two of the first heating element 40, the second heating element 41, and the third heating element 42, or the heating component 4 may include all of the first heating element 40, the second heating element 41, and the third heating element 42. The operator can select according to the actual installation situation and heating requirements, which facilitates the improvement of the flexibility of the heating component 4.

[0053] like Figure 1As shown, in some embodiments, the lampshade 2 further includes a connecting portion 21, which surrounds the transparent portion 20 and fits between the transparent portion 20 and the lamp housing 1. The lower part of the connecting portion 21 is recessed downward to define a portion of the second chamber 10b. The heating assembly 4 is disposed on the inner surface of the second chamber 10b. The heating assembly 4 includes at least one of a first heating element 40, a second heating element 41, and a third heating element 42. The first heating element 40 is disposed on the side wall of the connecting portion 21 in a first horizontal direction, the second heating element 41 is disposed on the bottom wall of the connecting portion 21, and the third heating element 42 is disposed on the bottom wall of the lamp housing 1, and the third heating element 42 is disposed adjacent to the connecting portion 21.

[0054] As can be seen, the transparent portion 20 is fitted to the lamp housing 1 via the connecting portion 21. When the first heating element 40 is assembled, it can be first fixed to the side wall of the connecting portion 21 in the first horizontal direction, and then the connecting portion 21 is fitted to the lamp housing 1 to complete the assembly of the first heating element 40. When the second heating element 41 is assembled, it can be first fixed to the bottom wall of the connecting portion 21, and then the connecting portion 21 is fitted to the lamp housing 1 to complete the assembly of the second heating element 41. When the third heating element 42 is assembled, it can be first fixed to the bottom wall of the lamp housing 1, and then the connecting portion 21 is fitted to the lamp housing 1 to complete the assembly of the third heating element 42. Therefore, the assembly of the first heating element 40, the second heating element 41, and the third heating element 42 is relatively simple, which facilitates the improvement of the assembly efficiency of the vehicle lamp 100. It is understood that the assembly methods of the first heating element 40, the second heating element 41 and the third heating element 42 have been clearly described in the above discussion, and the assembly method of the combination of the first heating element 40, the second heating element 41 and the third heating element 42 will not be repeated below.

[0055] In some embodiments, at least one of the first heating element 40, the second heating element 41, and the third heating element 42 is a graphene heating sheet. The graphene heating sheet has the characteristics of fast heating, high heating efficiency, good flexibility, and good plasticity. The graphene heating sheet increases the dew point of the air inside the vehicle lamp 100 by heating, thereby reducing the humidity saturation in the air. Moreover, the graphene heating sheet can adapt to the design of vehicle lamps 100 with different shapes and sizes, so that the applicability of the first heating element 40, the second heating element 41, and the third heating element 42 is better and it is less likely to affect the arrangement of other components inside the vehicle lamp 100.

[0056] like Figure 1As shown, in some embodiments, the transparent portion 20 includes a first wall 20a and a second wall 20b. The first wall 20a corresponds to the light source assembly 3, and the second wall 20b is connected to the lower end of the first wall 20a. The second wall 20b extends from the first wall 20a along a first horizontal direction toward the side where the lamp housing 1 is located. For example, the first wall 20a is vertically arranged, and the second wall 20b is horizontally arranged, so that the first wall 20a and the second wall 20b form an "L" shape. The structure is relatively simple and easy to manufacture. The connecting portion 21 corresponds to the second chamber 1. Part 0b includes a third wall 21a, a fourth wall 21b, and a fifth wall 21c. The fourth wall 21b is vertically arranged. The third wall 21a and the fifth wall 21c are respectively connected to the upper and lower ends of the fourth wall 21b. The third wall 21a and the fifth wall 21c extend away from each other in the first horizontal direction from the fourth wall 21b. The fifth wall 21c extends towards the lamp housing 1 and is matched with the lamp housing 1. Thus, the third wall 21a, the fourth wall 21b, and the fifth wall 21c are roughly arranged in a "Z" shape. The structure is relatively simple and easy to process and manufacture.

[0057] The third wall 21a and the second wall 20b are stacked vertically to increase the mating area between the transparent portion 20 and the connecting portion 21, thereby increasing the connection strength between them and improving the stability of the lampshade 2 during use. Furthermore, the fifth wall 21c facilitates the mating of the lamp housing 1 and the lampshade 2 along the first horizontal direction without affecting their mating method. It can be understood that the fourth wall 32b can be the side wall of the connecting portion 21 in the first horizontal direction, the fifth wall 21c can be the bottom wall of the connecting portion 21, and the part of the lamp housing 1 that mates with the fifth wall 21c can be the bottom wall of the lamp housing 1.

[0058] For example, if the connecting portion 21 participates in defining the airflow channel 22, it is convenient to extend the airflow channel 22 toward the lower end of the transparent portion 20. For example, the fourth wall 21b and the third wall 21a participate in defining the airflow channel 22. The lower end of the airflow channel 22 connects to the space formed by the downward indentation of the lower part of the connecting portion 21. At the same time, the heating component 4 is provided on or near the connecting portion 22, so the surrounding space heated by the heating component 4 can flow to the lampshade 2 more timely through the airflow channel 22.

[0059] like Figure 1As shown, in some embodiments, the connecting portion 21 is constructed as a non-transparent component, and the heating component 4 is correspondingly disposed at the lower part of the connecting portion 21. The heating component 4 can be disposed in the space formed by the downward indentation at the lower part of the connecting portion 21, or the heating component 4 can be disposed adjacent to the space formed by the downward indentation at the lower part of the transparent portion 20, so that the heating component 4 and the transparent portion 20 have a certain distance in the vertical direction. The heating component 4 is less likely to affect the light emitted from the light source component 3 from passing through the transparent portion 20, which is conducive to improving the stability of the vehicle lamp 100. At the same time, the connecting portion 21 can block the heating component 4 so that the user cannot see the heating component 4 through the transparent portion 20, which is conducive to improving the aesthetics of the vehicle lamp 100.

[0060] For example, the portion of the connecting part 21 corresponding to the second chamber 10b includes a third wall 21a, a fourth wall 21b, and a fifth wall 21c. The fourth wall 21b is vertically arranged. The third wall 21a and the fifth wall 21c are respectively connected to the upper and lower ends of the fourth wall 21b, and the two extend away from each other in a first horizontal direction from the fourth wall 21b. The fifth wall 21c extends toward the lamp housing 1 and cooperates with the lamp housing 1. The heating component 4 can be disposed on the fourth wall 21b, or the heating component 4 can be disposed on the fifth wall 21c, or the heating component 4 can be disposed on the wall surface of the portion of the fifth wall 21c that cooperates with the lamp housing 1, so that the heating component 4 does not easily affect the light emitted by the light source component 3 from passing through the transparent part 20, and the user cannot see the heating component 4 through the transparent part 20.

[0061] like Figure 1 As shown, in some embodiments, the connecting portion 21 is constructed as a non-transparent component. The heating assembly 4 is disposed corresponding to the lower part of the connecting portion 21. The heating assembly 4 includes at least one of a first heating element 40, a second heating element 41, and a third heating element 42. The first heating element 40 is disposed on the side wall of the connecting portion 21 in a first horizontal direction, the second heating element 41 is disposed on the bottom wall of the connecting portion 21, and the third heating element 42 is disposed on the bottom wall of the lamp housing 1, and the third heating element 42 is disposed adjacent to the connecting portion 21. It can be seen that the first heating element 40, the second heating element 41, and the third heating element 42 are all disposed in the area corresponding to the lower part of the connecting portion 21, so that the heating assembly 4 does not easily affect the light emitted from the light source assembly 3 from passing through the transparent portion 20. At the same time, the user cannot see the heating assembly 4 through the transparent portion 20, thereby improving the performance of the vehicle lamp 100.

[0062] like Figure 1As shown, in some embodiments, the vehicle light 100 further includes a radiator 5 and a fan 6. The radiator 5 is disposed in the mounting cavity 10, and the radiator 5 is located on the side of the light source assembly 3 away from the transparent portion 20 in the first horizontal direction, so that the radiator 5 does not easily affect the normal operation of the light source assembly 3. The radiator 5 and the light source assembly 3 are thermally conductively connected, and the heat generated by the light source assembly 3 during operation can be transferred to the radiator 5 for dissipation, so that the light source assembly 3 can be maintained at a more suitable temperature for operation, which is conducive to improving the stability of the operation of the light source assembly 3. The fan 6 is disposed in the mounting cavity 10, and the fan 6 is adapted to be powered independently from the light source assembly 3, so that the power supply and control of the fan 6 and the light source assembly 3 can be independent and not easily interfere with each other. For example, the fan 6 can be started alone, or the light source assembly 3 can be started alone, or the fan 6 and the light source assembly 3 can be started simultaneously, which is convenient to meet different usage conditions. The fan 6 is located on the side of the radiator 5 away from the transparent portion 20 in the first horizontal direction, so that the fan 6 does not easily affect the normal operation of the light source assembly 3. At the same time, the fan 6 can accelerate the dissipation of heat on the radiator 5 and accelerate the heat transfer between the radiator 5 and the light source assembly 3, which is beneficial to improving the heat dissipation efficiency of the radiator 5. Clearly, the fan 6 and the light source assembly 3 are powered independently, so that the fan 6 can run even when the light source assembly 3 is not working, thereby speeding up the defogging efficiency.

[0063] For example, the fan 6 and the light source assembly 3 are adapted to be connected to different power supplies. When the vehicle 200 is not running, the fan 6 can be started independently to allow the airflow heated by the heating component 4 to flow faster, thereby improving the efficiency of removing fog and water droplets. Of course, in other embodiments of this application, the fan 6 and the light source assembly 3 can also be connected to the same power supply, using different control switches to control the electrical connection between the fan 6 and the light source assembly 3 and the power supply, so as to meet the independent control of the fan 6 and the light source assembly 3. In this case, the fan 6 and the light source assembly 3 can be arranged in parallel.

[0064] The fan 6 is configured such that its rotation direction is adjustable, allowing it to switch between the air inlet and outlet ends facing the radiator 5. For example, when the outlet end of the fan 6 faces the radiator 5, the fan 6 can accelerate the airflow between the radiator 5 and the light source assembly 3, thereby improving the heat dissipation efficiency of the radiator 5. When the air inlet end of the fan 6 faces the radiator 5, the fan 6 can accelerate the airflow within the mounting cavity 10. The airflow heated by the heating assembly 4 and flowing to the lamp cover 2 can then flow faster, allowing the heated airflow to flow more quickly along the inner wall of the transparent portion 20. This facilitates the removal of fog and water droplets, and helps improve the stability of the vehicle lamp 100.

[0065] It is evident that the above-mentioned configuration of fan 6 can not only meet the heat dissipation requirements of light source component 3, but also accelerate the airflow inside the headlight 100 and accelerate the airflow used to defog the lamp cover 2, which is conducive to further improving the problems of fog and water droplets inside the headlight 100.

[0066] The vehicle 200 according to the second aspect of the present invention includes the headlights 100 according to the first aspect of the present invention.

[0067] According to the embodiment of the present utility model, the vehicle 200, by adopting the above-mentioned headlight 100, has good defogging ability, which facilitates the improvement of the safety of the vehicle 200 operation.

[0068] It is understood that the specific type of vehicle 200 referred to in the embodiments of this application is not limited. For example, vehicle 200 can be a fuel vehicle, a gas vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, range-extended electric vehicles, solar electric vehicles, gas fuel vehicles (such as hydrogen engine vehicles), or biofuel vehicles (such as vehicles powered by ethanol, biodiesel, etc.).

[0069] Other configurations and operations of the vehicle 200 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0070] In some embodiments, the vehicle 200 is configured to satisfy at least one of the following conditions A1 to A3:

[0071] In condition A1, vehicle 200 also includes a processor, a first temperature detector and a first humidity detector. The first temperature detector is used to detect the ambient temperature and the first humidity detector is used to detect the ambient humidity. The first temperature detector and the first humidity detector communicate with the processor respectively. The processor is used to determine whether to turn on the heating component 4 and to determine the heating duration of the heating component 4 based on the detection results of the first temperature detector and the first humidity detector.

[0072] As can be seen, the first temperature detector and the first humidity detector can detect the temperature and humidity of the operating environment of the vehicle 200, and indirectly reflect the temperature and humidity of the external environment of the headlight 100. The first temperature detector and the first humidity detector can feed back the detection results to the processor. The processor can obtain the dew point temperature of the current environment based on the detection results of the first temperature detector and the first humidity detector, and thus determine whether to turn on the heating component 4 and the heating duration of the heating component 4. Thus, when it is necessary to defog the headlight cover 2, the fog and water droplets on the headlight 100 can be automatically removed, so that the headlight 100 can always maintain a good lighting effect, which can improve the safety of the vehicle 200 operation.

[0073] Dew point temperature refers to the temperature at which air reaches saturation when the water vapor content in the air remains constant and the air pressure is kept constant. When the ambient temperature is lower than the dew point temperature, phenomena such as fogging or water droplet precipitation are more likely to occur.

[0074] For example, the processor can obtain the current ambient dew point temperature T1 and the current ambient temperature T2 based on the detection results of the first temperature detector and the first humidity detector. The operator sets a preset threshold for T2 / T1. When the processor determines that the ratio of the current ambient temperature to the dew point temperature reaches the preset threshold, it turns on the heating component 4 to defog the headlight 100. At the same time, the interval corresponding to the current ambient temperature to dew point temperature reaching the preset threshold is divided into multiple sub-intervals, including the first sub-interval to the Nth sub-interval. From the first sub-interval to the Nth sub-interval, the degree to which the current ambient temperature is lower than the preset threshold increases, and the heating time of the corresponding heating component 4 is extended. For example, N is taken as 3, the preset threshold T2 / T1 = 1.15, the interval corresponding to the current ambient temperature to dew point temperature reaching the preset threshold is subdivided into three sub-intervals, and a corresponding heating time of the heating component 4 is set for each sub-interval. For example, in the first sub-interval, 1.05 ≤ T2 / T1 ≤ 1.15, meaning the ratio of the current ambient temperature to the dew point temperature is set between 1.05 and 1.15, the heating component 4 stops operating after 5 minutes. In the second sub-interval, 9.5 ≤ T2 / T1 < 1.05, meaning the ratio of the current ambient temperature to the dew point temperature is set between 0.95 and 1.05, the heating component 4 stops operating after 10 minutes. In the third sub-interval, T2 / T1 < 0.95, meaning the ratio of the current ambient temperature to the dew point temperature is less than 0.95, the heating component 4 stops operating after 15 minutes. As the ratio of the current ambient temperature to the dew point temperature decreases, the operating time of the heating component 4 increases accordingly, which can effectively remove fog from the headlights 100 without wasting too much energy.

[0075] Of course, the values ​​of N and the preset threshold can be flexibly adjusted according to actual usage to meet the needs of different vehicles in different usage environments, so as to achieve the best effect of removing fog from headlights.

[0076] In this embodiment, the preset threshold can be pre-set in the vehicle 200 by the designer before the vehicle 200 leaves the factory.

[0077] In condition A2, vehicle 200 also includes a processor, a second temperature detector and a second humidity detector. The second temperature detector is used to detect the temperature inside the mounting cavity 10 at preset intervals, and the second humidity detector is used to detect the humidity inside the mounting cavity 10 at preset intervals. The second temperature detector and the second humidity detector communicate with the processor respectively. The processor is used to determine whether to turn the heating component 4 on or off based on the detection results of the second temperature detector and the second humidity detector.

[0078] As can be seen, the second temperature detector and the second humidity detector are used to detect the temperature and humidity inside the mounting cavity 10 at preset intervals. That is, the second temperature detector and the second humidity detector can be set inside the mounting cavity 10 so as to more accurately reflect the temperature and humidity of the internal environment of the vehicle lamp 100. The second temperature detector and the second humidity detector can feed back the detection results to the processor. The processor can obtain the dew point temperature inside the mounting cavity 10 based on the current detection results of the second temperature detector and the second humidity detector, and thus determine whether to turn on the heating component 4 or turn off the heating component 4. In this way, when the lamp cover 2 needs to be defogged, the fog and water droplets on the vehicle lamp 100 can be automatically removed so that the vehicle lamp 100 can always maintain a good lighting effect, which can improve the safety of the vehicle 200 operation. When the lamp cover 2 does not need to be defogged or after defogging is completed, the heating component 4 is turned off.

[0079] For example, the processor can obtain the dew point temperature T3 inside the mounting cavity 10 and the temperature inside the mounting cavity 10 is T4 based on the current detection results of the second temperature detector and the second humidity detector. The operator sets a preset threshold for T4 / T3. When the processor determines that the ratio of the temperature inside the mounting cavity 10 to the dew point temperature reaches the preset threshold, for example, the preset threshold T4 / T3 = 1.15, the heating component 4 is turned on to perform defogging on the headlight 100. The second temperature detector and the second humidity detector can detect the temperature and humidity inside the mounting cavity 10 at intervals (for example, 30 seconds or 1 minute) and transmit the current detection results of the second temperature detector and the second humidity detector to the processor. When the processor determines that the ratio of the current temperature inside the mounting cavity 10 to the dew point temperature is greater than the preset threshold, the heating component 4 is turned off to reduce energy waste. In other words, after the heating component 4 is turned on, the heating component 4 remains in a heating state until the processor determines that defogging is completed or that a state where fog is not likely to form is reached based on the current detection results of the second temperature detector and the second humidity detector.

[0080] In condition A3, vehicle 200 also includes a processor, a temperature detection component, and a humidity detection component. The temperature detection component is used to detect the ambient temperature and / or the temperature inside the mounting cavity 10. The humidity detection component is used to detect the ambient temperature and / or the humidity inside the mounting cavity 10. The temperature detection component and the humidity detection component communicate with the processor. The processor is used to record the user's driving habits and to determine whether to turn on the heating component 4 before starting the vehicle 200 and to determine the heating duration of the heating component 4 based on the detection results of the temperature detection component and the humidity detection component and the driving habits.

[0081] As can be seen, the processor can record the user's driving habits. Based on these habits, the processor can determine when the vehicle 200 will start. Furthermore, based on the detection results of the temperature and humidity detection components (which could be the detection results at a certain moment before the vehicle 200 starts), the processor can determine whether the heating component 4 needs to be turned on before the vehicle 200 starts and the duration of heating of the heating component 4. This enables the automatic removal of fog and water droplets from the headlights 100, ensuring that the fog and water droplets on the headlights 100 are effectively removed when the user is using the vehicle 200. This provides the headlights 100 with good illumination and helps to eliminate the user's misunderstanding that "the headlights are wet."

[0082] For example, the temperature detection component includes a first temperature detector for detecting ambient temperature, and the humidity detection component includes a first humidity detector for detecting ambient humidity. When the detection results of the first temperature detector and the first humidity detector reach the corresponding preset threshold, the processor determines the heating time required to remove fog and water droplets from the headlight 100 based on the detection results of the first temperature detector and the first humidity detector, thereby achieving better removal of fog and water droplets from the headlight 100. For example, if condensation has already occurred on the headlight 100, the processor determines, based on the detection results of the first temperature detector and the first humidity detector, that the heating component 4 needs to heat for 15 minutes to remove the fog and water droplets from the headlight 100. Since the user usually starts the vehicle 200 around 7:45, the processor can start the heating component 4 15 minutes earlier, at 7:30, so that the fog and water droplets on the headlight 100 can be removed well, allowing the headlight 100 to have a good lighting effect when the user uses the vehicle 200.

[0083] For example, the temperature detection component includes a second temperature detector for detecting the temperature inside the mounting cavity 10, and the humidity detection component includes a second humidity detector for detecting the humidity inside the mounting cavity 10. When the detection results of the second temperature detector and the second humidity detector reach the corresponding preset threshold, the processor determines the heating time required to remove fog and water droplets from the headlight 100 based on the detection results of the second temperature detector and the second humidity detector, thereby achieving better removal of fog and water droplets from the headlight 100. For example, if condensation has already occurred on the headlight 100, the processor determines, based on the detection results of the second temperature detector and the second humidity detector, that the heating component 4 needs to heat for 20 minutes to remove the fog and water droplets from the headlight 100. Since the user usually starts the vehicle 200 around 7:30, the processor can start the heating component 4 20 minutes earlier, at 7:10, so that the fog and water droplets on the headlight 100 can be removed well, allowing the headlight 100 to have a good lighting effect when the user uses the vehicle 200.

[0084] For example, the temperature detection component includes a second temperature detector, which is used to detect the temperature inside the mounting cavity 10 at preset intervals. The humidity detection component includes a second humidity detector, which is used to detect the humidity inside the mounting cavity 10 at preset intervals. When the detection results of the second temperature detector and the second humidity detector reach the corresponding preset threshold, the heating component 4 is turned on in advance before the vehicle 100 starts, and the heating component 4 is turned off until the detection results of the second temperature detector and the second humidity detector reach the corresponding preset threshold. As for how long in advance relative to the start of the vehicle 100, it can be set according to actual needs.
