Description

Technical Field

[0001] This invention belongs to the automotive field, and more specifically, relates to a fog light. Background Technology

[0002] When driving in adverse weather conditions such as fog, snow, and heavy rain, or in dusty environments, front fog lights are essential for illuminating the road ahead and ensuring driving safety. Traditionally, fog lights are often mounted directly on the vehicle body. However, when the vehicle travels over rough roads, bumps can cause impacts to the fog lights, leading to damage and seriously affecting driving safety. While some existing technologies exist for shock-absorbing structures between the headlights and the vehicle body, most are bracket-type adjustments, offering poor shock absorption and being complex and difficult to install. Furthermore, fog lights frequently require fine-tuning at a certain angle, which existing shock-absorbing structures cannot easily achieve, making them inconvenient to use. Summary of the Invention

[0003] The purpose of this invention is to provide a fog light that solves the problems of poor shock absorption and difficulty in fine-tuning the fog light angle in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A fog light is provided, comprising: The fog light body is used to generate preset light and has a central axis extending along the light output direction; The first connector is offset from the central axis and connected to one side of the fog light body; The second connector is slidably connected to the fog light body. The second connector and the first connector are distributed along the central axis of the fog light body. The fog light body is connected to the vehicle body through the second connector. A guide member extends along a first direction and is connected to a second connector to guide the second connector to move along the first direction; the first connector is slidably connected to the guide member for sliding relative to the guide member along the first direction. An adjusting member, connected to the guide member and the second connecting member, is used to adjust the relative position of the first connecting member and the second connecting member in the first direction; The first elastic element is an elastic structure connected to the first connector and the second connector, and is used to push the first connector and the second connector away from each other.

[0005] The fog light provided by this invention is slidably connected to a second connector and connected to the vehicle body via the second connector. A first connector is connected to a side offset from the central axis of the fog light body. Through the cooperation of an adjusting member and a guide member, the second connector can be moved along the guide member in a first direction. The second connector can move towards the first connector to reduce the distance between them, or it can move away from the first connector to increase the distance between them. Because the first connector is offset from the central axis of the fog light body, the angle of the fog light body can be changed by adjusting the relative distance between the first and second connectors, thereby further adjusting the direction of illumination. Furthermore, since the first connector is fixedly connected to the fog light body, and the second connector is slidably connected to the fog light body, when the fog light body is subjected to an impact force in the first direction, the first and second connectors move closer together. A first elastic member located between the first and second connectors can then push the first and second connectors away from each other, providing shock absorption and preventing damage to the fog light from impacts, thus improving its lifespan and surpassing existing technologies.

[0006] In some implementations, the adjusting member is provided with a threaded through hole, and the guide member is provided with a corresponding thread distributed along the first direction. The adjusting member and the guide member are connected by a threaded structure. The adjusting member is mounted on the second connecting member, and the guide member is used to rotate relative to the adjusting member in a second direction, thereby adjusting the relative position of the first connecting member and the second connecting member in the first direction; The first direction is perpendicular to the second direction.

[0007] The fog light provided by this invention utilizes a threaded engagement structure that features relative movement and self-locking. The guide and adjustment components are connected by a threaded structure. By rotating the guide, the relative position of the second connecting component on the guide can be easily adjusted, and the second connecting component is self-locked when the guide stops rotating, resulting in a highly flexible adjustment effect.

[0008] In some implementations, the second connector is provided with a through hole for the fog lamp body to pass through, the second connector abuts against the fog lamp body through the through hole and supports the fog lamp body; a gap is left between the through hole and the fog lamp body to allow the fog lamp body to rotate.

[0009] The fog light provided by the present invention utilizes the through hole formed on the second connector to support the fog light body, which not only facilitates the fixed installation of the fog light body, but also allows the orientation of the fog light body to be adjusted by adjusting the guide, so that the angle of the fog light provided by the present invention can be finely adjusted within a certain range, which is superior to the prior art.

[0010] In some implementations, the second connector has a first mounting surface and a second mounting surface, the first mounting surface and the second mounting surface being distributed along the direction of the central axis, and the first mounting surface being disposed between the second mounting surface and the first connector; The through hole is formed on the first mounting surface; The adjusting element is mounted on the second mounting surface.

[0011] The fog light provided by the present invention has a first mounting surface and a second mounting surface distributed along the central axis on the second connector, which can effectively increase the length of the guide and enable the fog light provided by the present invention to have a larger angle adjustment range.

[0012] In some implementations, the second connector forms a cavity extending along the first direction, and the adjusting member is housed inside the cavity and abuts against the wall of the cavity; The end of the cavity along the first direction is set in an open state so as to allow the adjusting member to be separated from the second connecting member through the opening; The adjusting member has a non-rotational structure in the second direction, and the second connecting member is used to form the wall surface of the cavity, which has a non-rotational structure adapted to the adjusting member in the second direction.

[0013] The fog light provided by the present invention has a cavity for accommodating the adjustment member on the second connector, and the cavity also has an opening for the adjustment member to disengage. When the guide member is subjected to an impact force along the first direction, it can drive the adjustment member to disengage from the cavity, avoiding excessive impact force causing damage to the threads between the guide member and the adjustment member, further preventing the adjustment function from failing, and greatly improving the service life of the structure.

[0014] In some implementations, the fog light body is formed with an optical system, the optical system comprising: The lamp tube forms a cavity with an opening on one side; A light source, used to emit preset light rays; A lens having an incident surface and a refractive surface, the incident surface being used to form the focal point of the lens, and the refractive surface protruding in a direction away from the incident surface and corresponding to the opening; The refractive surface is divided into several adjustment units, each of which has a separate preset radius of curvature to adjust the refraction direction of the preset light and to ensure that all the refracted preset light passes through the opening. The light source and the lens are disposed inside the cavity, with the light source positioned at the focal point of the lens.

[0015] The fog light provided by this invention, through an optical system formed by the fog light body, not only simplifies the system structure and improves the overall shock resistance, but also reduces the refraction angle of light at the edge of the lens refractive surface, causing the light refracted at the edge of the refractive surface to converge more towards the central area of ​​the refractive surface, achieving the effect of converging the refracted light and preventing some light from being scattered into ineffective illumination areas and becoming ineffective light. Compared with the prior art, the fog light provided by this invention can effectively improve illumination efficiency and reduce energy consumption, effectively reducing fog light power while maintaining the same illumination brightness.

[0016] Some implementations also include light-blocking components; The light-blocking component is disposed between the light source and the lens, and the light-blocking component has a light pattern notch of a preset shape to allow the preset light emitted by the light source to pass through and form a preset light pattern.

[0017] The fog light provided by the present invention also includes a light-blocking component in its optical system. The desired light pattern shape can be easily obtained through the light pattern notch of a preset shape set on the light-blocking component, which has a wide range of applications.

[0018] Some implementations also include tempered glass; The tempered glass is disposed at the opening of the cavity and is used to seal the cavity.

[0019] The fog light provided by this invention has an optical system in which the refractive surface of the lens is not a smooth spherical structure. Therefore, it is made of a plastic material that is easier to process. Taking advantage of the good impact resistance of tempered glass, the lens and the light source are encapsulated in a sealed lamp tube, which significantly improves the impact resistance of the fog light of this invention.

[0020] In some implementations, the lamp tube includes a lamp holder and a lamp body; The lamp holder and the lamp body each form a portion of the mounting cavity; The light source, the lens, and the light-blocking component are disposed within the mounting cavity; The lamp holder and the lamp body are sealed together.

[0021] The fog light provided by this invention utilizes the lamp head and the lamp body to each form a partial mounting cavity for mounting structures such as light sources and lenses, which facilitates the subsequent disassembly and maintenance of the fog light provided by this invention; the sealed connection between the lamp head and the lamp body enables the fog light to be waterproof.

[0022] In some implementations, the lamp body is provided with heat dissipation fins for heat dissipation.

[0023] The fog light provided by this invention can effectively dissipate heat from the lamp body by utilizing the heat dissipation fins provided on the lamp body. Attached Figure Description

[0030] The fog lights provided in the embodiments of the present invention will now be described.

[0031] See Figure 1As shown in Figure 2, an embodiment of the present invention provides a fog light, specifically including a fog light body 100, a first connecting member 200, a second connecting member 300, a guide member 400, an adjusting member 500, and a first elastic member 600. The fog light body 100 is used to generate preset light and has a central axis extending along the light emission direction. The first connecting member 200 is offset from the central axis of the fog light and connected to one side of the fog light body 100. (See reference...) Figure 3 In this embodiment, the shape and structure of the first connector 200 are not limited, and can be a commonly used connecting structure in the art, such as a plate structure or a rod structure. Of course, in some other embodiments, the first connector 200 can also be integrally formed into the fog lamp body 100. For ease of explanation, this embodiment uses a plate-shaped first connector 200 for description.

[0032] The second connector 300 is connected to the fog lamp body 100. The second connector 300 and the first connector 200 are distributed along the central axis of the fog lamp body 100, and the fog lamp body 100 is connected to the vehicle body through the second connector 300. The shape and structure of the second connector 300 described in this embodiment are not limited, and can be a commonly used connection structure in the art, such as a plate structure, a rod structure, etc. For ease of explanation, the second connector 300 in this embodiment is also described as a plate structure.

[0033] See Figure 6 The guide member 400 extends along a first direction. In this embodiment, the first direction can be any direction. The maximum distance the guide member 400 extends along this direction is the maximum travel distance of the first connecting member 200 and the second connecting member 300 on the guide member 400. The guide member 400 is connected to the second connecting member 300 and guides the second connecting member 300 to move along the first direction. The first connecting member 200 is slidably connected to the guide member 400 and slides relative to the guide member 400 along the first direction. It is understood that the guide member 400 described in this embodiment can be a rod-like structure, a bar-like structure, or a plate-like structure, etc., having an extension distance in the first direction and allowing the first connecting member 200 and the second connecting member 300 to move relative to the guide member 400 along the first direction. It is worth noting that movement along the first direction can be forward movement or movement in the opposite direction.

[0034] The adjusting member 500 is connected to the guide member 400 and the second connecting member 300, and is used to adjust the relative position of the first connecting member 200 and the second connecting member 300 in the first direction. Taking the first connecting member 200 and the second connecting member 300 as plate-like structures and the guide member 400 as rod-like structures as an example, in this embodiment, the adjusting member 500 can be configured as an annular structure fixedly connected to the second connecting member 300 and sleeved on the guide member 400. By moving the adjusting member 500, the second connecting member 300 can be driven to move relative to the guide member 400 in the first direction. The purpose of setting the adjusting member 500 is to prevent the second connecting member 300 from disengaging from the guide member 400. In this embodiment, the adjusting member 500 can be further adapted to the guide member 400 to form a relatively stable connection between the two. For example, the annular adjusting member 500 can be connected to the guide member 400 through a damping fit or a threaded fit, so that the second connecting member 300 can be conveniently stopped at a certain position on the guide member 400 and has a relatively fixed distance from the first connecting member 200, so as to achieve the effect of distance adjustment.

[0035] The first elastic element 600, as described in this embodiment, is an elastic structure. Its function is to connect the first connector 200 and the second connector 300, and to push the first connector 200 and the second connector 300 away from each other, so as to achieve the technical effect of shock absorption when the first connector 200 or the second connector 300 is impacted.

[0036] The fog light provided in this embodiment is connected to the vehicle body via a second connector 300. A first connector 200 is connected to a side offset from the central axis of the fog light body 100. An adjusting member 500 and a guide member 400 cooperate with each other. The adjusting member 500 drives the second connector 300 to move along the guide member 400 in a first direction. The second connector 300 can move towards the first connector 200 to reduce the distance between them, or it can move away from the first connector 200 to increase the distance between them. Since the first connector 200 is offset from the central axis of the fog light body 100, the angle of the fog light body 100 can be changed by adjusting the relative distance between the first connector 200 and the second connector 300, so as to further adjust the direction of illumination.

[0037] In addition, since the first connector 200 is fixedly connected to the fog lamp body 100 and the second connector 300 is slidably connected to the fog lamp body 100, when the fog lamp body 100 is subjected to an impact force in the first direction, the first connector 200 and the second connector 300 move closer to each other, while the first elastic member 600 located between the first connector 200 and the second connector 300 can be used to push the first connector 200 and the second connector 300 away from each other, which has the technical effect of shock absorption and avoiding damage to the fog lamp from impact, thus improving its lifespan.

[0038] See Figure 7 In some embodiments, the adjusting member 500 is specifically configured to have a threaded through hole, and as a matching structure, the guide member 400 is correspondingly provided with threads distributed along the first direction. For ease of explanation, the adjusting member 500 in this embodiment can be configured as a nut, and the guide member 400 can be configured as a threaded screw or lead screw, with the adjusting member 500 and the guide member 400 connected by a threaded structure. More specifically, the adjusting member 500 is mounted on the second connecting member 300 and is used to drive the second connecting member 300 to move along the first direction on the guide member 400. In this embodiment, the guide member 400 is used to rotate relative to the adjusting member 500 along the second direction, thereby causing the adjusting member 500 to move along the first direction on the guide member 400 and drive the second connecting member 300. It can be understood that the guide member 400 can also rotate relative to the adjusting member 500 in the opposite direction of the second direction, thereby causing the adjusting member 500 to move along the guide member 400 in the opposite direction of the first direction. It is understood that in this embodiment where the guide 400 and the adjusting member 500 are connected by threads, the first direction and the second direction are set to be perpendicular to each other.

[0039] In this embodiment, the guide member 400 and the adjusting member 500 are interconnected via a threaded structure, utilizing the self-locking characteristic of the threaded connection. When the guide member 400 stops rotating, the adjusting member 500 and the second connecting member 300 can remain at a certain position on the guide member 400 in the first direction. This allows the second connecting member 300 to be conveniently positioned on the guide member 400 and maintain a relatively fixed distance from the first connecting member 200, achieving the effect of distance adjustment. Therefore, it can be understood that the guide member 400 and the adjusting member 500 can also be interconnected via other self-locking structures, such as damping structures. Specifically, the guide member 400 and the adjusting member 500 have frictional damping in the first direction. Applying an external force allows the adjusting member 500 to move in the first direction, while without applying an external force, the guide member 400 and the adjusting member 500 maintain a defined relative positional relationship through the frictional damping between them. Compared to the implementation in this embodiment where the guide member 400 and the adjusting member 500 are connected via a threaded structure, its stability is lower, but it still has a certain adjustment effect.

[0040] In some embodiments, the second connector 300 is provided with a through hole for the fog lamp body 100 to pass through. The second connector 300 abuts against the fog lamp body 100 through the through hole and provides support for the fog lamp body 100. Additionally, the through hole allows the fog lamp body 100 to be slidably connected to the second connector 300. A gap is provided between the through hole and the fog lamp body 100 to allow the fog lamp body 100 to rotate, providing rotational space when the angle of the fog lamp body 100 changes. It is understood that the shape of the through hole in this embodiment is not limited and can be a circle, square, or other shape suitable for the fog lamp body 100 commonly used in the prior art. It is also worth noting that providing a through hole on the second connector 300 and slidingly connecting it to the fog lamp body 100 through this through hole is a preferred implementation method selected in this embodiment. In other embodiments, the fog lamp body 100 may also achieve a sliding connection using structures such as snap-fit ​​and slot, all of which should be considered within the scope of protection of this invention and will not be elaborated further here.

[0041] See Figure 4 and Figure 5 In some embodiments, the second connector 300 preferably has a first mounting surface 301 and a second mounting surface 302. Specifically, the first mounting surface 301 and the second mounting surface 302 are distributed along the central axis of the fog lamp body 100, and the first mounting surface 301 is disposed between the second mounting surface 302 and the first connector 200. A through hole is formed on the second connector 300 in the first mounting surface 301; the adjusting member 500 is mounted on the second mounting surface 302. Forming the first mounting surface 301 and the second mounting surface 302 distributed along the central axis on the second connector 300 can effectively increase the length of the guide member 400, allowing the fog lamp provided by the present invention to have a larger angle adjustment range. The distance between the first mounting surface 301 and the second mounting surface 302 can be flexibly set according to the needs of the actual scenario.

[0042] In some embodiments, the second connector 300 preferably has a cavity extending along a first direction. The adjusting member 500 is housed inside the cavity and abuts against the wall of the cavity. The adjusting member 500 moves the second connector 300 by abutting against the wall of the cavity. The end of the cavity along the first direction is set in an open state so that the adjusting member 500 can be separated from the second connector 300 through the opening. According to this structure, when the guide member 400 and the adjusting member 500 are subjected to external impact force, they can be separated from the cavity provided on the second connector 300, which can effectively alleviate the force between the guide member 400 and the adjusting member 500. For example, in an embodiment where the guide 400 and the adjusting member 500 are connected by a threaded structure, a cavity for accommodating the adjusting member 500 is provided on the second connecting member 300, allowing the adjusting member 500 to disengage from the cavity. When the guide 400 is subjected to an impact force along the first direction, the guide 400 can drive the adjusting member 500 to move along the first direction and disengage from the cavity provided on the second connecting member 300, reducing the stress on the threaded connection structure between the guide 400 and the adjusting member 500 and significantly improving the service life of the shock-absorbing and adjusting structure.

[0043] In the above embodiments, the cavity on the second connector 300 has an open end along the first direction for disengaging the adjusting member 500. It is understood that in other embodiments, the cavity may also have an open end in the opposite direction to the first direction for disengaging the adjusting member 500 in the opposite direction, achieving the same technical effect as the above embodiments. Furthermore, in other embodiments, both ends of the cavity along the first direction are open, achieving the effect of disengaging the adjusting member 500 in the first direction or the opposite direction, with the same principle as the above embodiments, and will not be repeated here. It is understood that in embodiments where the cavity has only one opening for the adjusting member 500 to disengage, the cavity should also have at least another opening for the guide member 400 to pass through, so that the guide member 400 is connected to the adjusting member 500.

[0044] In this embodiment, the adjusting member 500 abuts against the wall of the cavity provided on the second connecting member 300 to drive the second connecting member 300 to move in the first direction. After the guide member 400 or the adjusting member 500 is impacted, it needs to disengage from the cavity provided on the second connecting member 300 that extends in the first direction. Therefore, in this embodiment, the abutment between the adjusting member 500 and the second connecting member 300 is a tight abutment, so that there is a certain frictional damping between the two. When the external force overcomes the frictional damping between the adjusting member 500 and the second connecting member 300, the adjusting member 500 can move relative to the second connecting member 300 and separate from the second connecting member 300. When the external force is insufficient to overcome the frictional damping between the adjusting member 500 and the second connecting member 300, the adjusting member 500 can drive the second connecting member to move in the first direction.

[0045] Understandably, the shape of the opening end of the cavity extending along the first direction provided on the second connector 300 is not limited. It can be a common shape in the prior art, such as a circle, square, or rectangle, or it can be a shape adapted to the adjusting member 500. Taking the adjusting member 500 as a nut structure for illustration, the shape of the opening end of the cavity can be flexibly set according to the shape of the nut structure.

[0046] In the above embodiments, since the adjusting member 500 and the second connecting member 300 are configured as separable connection structures, in order to avoid the adjusting member 500 spinning idly in the cavity provided on the second connecting member 300 and failing to drive the second connecting member 300 to move, the adjusting member 500 is a non-rotational structure in the second direction. The wall surface of the second connecting member 300 used to form the cavity has a non-rotational structure adapted to the adjusting member 500 in the second direction. Taking the adjusting member 500 as a hexagonal nut structure for explanation, the wall surface of the cavity along the second direction should also be configured as a hexagonal wall surface adapted to the hexagonal nut.

[0047] Based on the above embodiments, in some other embodiments of the present invention, the adjusting member 500 is preferably configured to have a connected first abutment surface 501 and abutment surface 502, wherein the first abutment surface 501 is configured as a spherical surface, and the second abutment surface 502 is a plane distributed along a second direction, so that the adjusting member 500 forms a non-rotational structure in the second direction. The cavity provided on the second connecting member 300 is correspondingly configured with a cavity shape adapted to the first abutment surface 501. The purpose of the above structural configuration is to provide a larger contact area between the adjusting member 500 and the second connecting member 300 through the spherical first abutment surface 501, and to prevent the adjusting member 500 from moving freely within the cavity. More specifically, the adjusting member 500 protrudes in the opposite direction to the first direction and forms a spherical surface, and the inner wall of the cavity forms a spherical surface adapted to the first abutment surface 501 for contact with the first abutment surface 501. According to the above structure, the adjusting member 500 can only be separated from the second connecting member 300 through the opening end of the cavity provided on the second connection. This not only has the technical effect of the adjusting member 500 and the second connecting member 300 being separable, but also prevents the adjusting member 500 from moving freely in the cavity.

[0048] In some other embodiments, the adjusting member 500 is selected as a hexagonal nut structure as an example. In this part of the embodiment, the contact surface between the adjusting member 500 and the second connecting member 300 is the sidewall of the hexagonal nut. Frictional damping is formed between the adjusting member 500 and the second connecting member 300 through the sidewall of the hexagonal nut and the cavity wall surface on the second connecting member 300. The adjusting member 500 can move inside the cavity in a first direction or the opposite direction. Compared with the embodiment described above where the adjusting member 500 is configured with a spherical first abutment surface 501 and a planar second abutment surface 502, its overall structural stability is poorer.

[0049] See Figure 8 In some embodiments, the fog light provided by the present invention preferably further includes a rotating member 700. In these embodiments, the rotating member 700 is designed to more conveniently drive the guide member 400 to rotate in the second direction. Taking the guide member 400 as a lead screw with a threaded structure as an example, the rotating member 700 can be connected to the guide member 400 by a threaded structure and is used to drive the guide member 400 to rotate in the second direction. It can be understood that the rotating member 700 has an extension portion in a direction perpendicular to the first direction and away from the guide member 400, so as to increase the rotational lever of the guide member 400, so that the operator can drive the guide member 400 to rotate with a smaller force and achieve a distance adjustment effect. More specifically, in these embodiments, the rotating member 700 can be specifically selected as a nut adapted to the guide member 400, and further, it can also be selected as a cap nut and installed at the end of the guide member 400.

[0050] Based on the embodiment where the guide member 400 is configured as a threaded screw or lead screw, and the adjusting member 500 and the rotating member 700 are connected to the guide member 400 via a threaded structure, the shock-absorbing adjustment structure provided by the present invention may preferably also include a second elastic member 800. The second elastic member 800 is configured as an elastic structure; specifically, the second elastic member 800 is connected to the rotating member 700 and the adjusting member 500 and is in a compressed state, used to provide a preload relative to the guide member 400 for the rotating member 700 and the adjusting member 500, effectively preventing the rotating member 700 from falling off the guide member 400. As a further preferred embodiment, in addition to the threaded connection between the rotating member 700 and the guide member 400, thread-locking adhesive can also be provided between the guide member 400 and the rotating member 700 to further enhance the connection stability between them. In some other embodiments, the rotating member 700 may also be directly configured as an integrally formed structure with the guide member 400.

[0051] See Figure 1 and Figure 2 It is understood that either the first elastic element 600 or the second elastic element 800 described in the embodiments of the present invention can be selected as a spring structure, or both can be selected as spring structures. In some embodiments, both the first elastic element 600 and the second elastic element 800 are selected as springs, and in these embodiments, both the first elastic element 600 and the second elastic element 800 are sleeved on the guide element 400. According to the above structure, the first elastic element 600 and the second elastic element 800 can not only achieve their respective effects, but also avoid redundant and complex connection or installation structures. The first elastic element 600 and the second elastic element 800 can ensure a stable connection with the guide element 400 and prevent them from falling off simply by being sleeved on the guide element 400, which has a flexible use effect.

[0052] In some embodiments, as a further preferred embodiment, the first connector 200 and the second connector 300 are preset to have a certain initial distance to keep the first elastic member 600 in a compressed state. Since the relative position of the second connector 300 on the guide member 400 along the first direction can be adjusted by the adjusting member 500, the initial distance between the first connector 200 and the second connector 300 can be adjusted by the adjusting member 500. It is understood that since the first elastic member 600 is preset to be in a compressed state, the first connector 200 and the second connector 300 are respectively subjected to a preset initial thrust applied by the first elastic member 600. The second connector 300, due to its connection with the adjusting member 500, has a fixed position relative to the guide member 400, while the first connector 200 is slidably connected to the guide member 400. It is understood that a limiting structure should also be provided on the other side of the first connector 200 to keep the position of the first connector 200 relative to the guide member 400 fixed under the thrust of the first elastic member 600.

[0053] See Figure 9 In some embodiments, the fog light body 100 specifically forms an optical system, which includes a lamp barrel 101, a light source 102, and a lens 103. The lamp barrel 101 is used to mount the light source 102 and the lens 103. Specifically, the lamp barrel 101 forms a cavity for mounting the light source 102 and the lens 103 and has an opening on one side for allowing a preset light emitted by the light source 102 to be emitted through this opening. It is understood that the specific shape of the lamp barrel 101 described in this embodiment is not limited. For example, it can be the shape used to mount the light source 102 and the lens 103 in a conventional fog light structure, or in other application scenarios, it can be set to an external shape suitable for the current operating conditions, with an opening on one side to allow the preset light generated by the light source 102 to be emitted.

[0054] In this embodiment, the light source 102 can be a conventional light source 102 or a commercially available LED light source 102. The light source 102 is disposed within the cavity formed by the lamp tube 101 and is used to emit preset light rays through an opening on one side of the cavity. A lens 103 is also disposed inside the cavity. The lens 103 has an incident surface 131 and a refractive surface 132. The shape of the incident surface 131 is used to form the focal point of the lens 103, and the light source 102 is disposed at the focal point of the lens 103. The incident surface 131 is used to receive light rays, while the refractive surface 132 is used to control the exit direction and refraction angle of the refracted light rays. The preset light rays enter the lens 103 through the incident surface 131 and exit the lens 103 through the refractive surface 132. In this embodiment, the refractive surface 132 is specifically configured as a curved structure, and the refractive surface 132 protrudes in a direction opposite to the incident surface 131. According to this structure, the aforementioned lens 103 is configured to resemble a convex lens 103 and has a light-focusing effect. The incident surface 131 can be set to be a plane or a curved surface. For ease of explanation, this embodiment describes the incident surface 131 as a plane.

[0055] See Figure 10 , Figure 11 and Figure 12 Furthermore, in this embodiment, the refractive surface 132 is pre-divided into several adjustment units, each with a separately preset radius of curvature to adjust the refraction direction of the preset light and ensure that all the refracted preset light passes through the opening formed on the lamp tube 101. Since the lens 103 itself has a certain thickness, by individually increasing or decreasing the radius of curvature within a certain adjustment unit, the thickness of the lens 103 within that adjustment unit can be increased or decreased accordingly, further increasing or decreasing the refraction angle of the refracted light, thereby achieving the technical effect of adjusting the refraction angle of the refracted light. According to this structure, it can effectively prevent a portion of the preset light generated by the light source 102 from failing to exit from one side opening of the lamp tube 101 and instead being scattered to the inner wall of the lamp tube 101 cavity and absorbed, becoming ineffective light. It is understood that the lens 103 provided in this embodiment is a finished lens 103, and the radius of curvature of each adjustment unit is not adjustable. The radius of curvature of the final finished product must be designed and formed during the manufacturing process to achieve the corresponding technical effect. Compared with the prior art, the optical system provided by the present invention can effectively reduce the generation of invalid light and improve the light utilization efficiency of the light source 102.

[0056] See Figure 13In some embodiments, as a further preferred embodiment, the optical system provided in some embodiments is further provided with a light-blocking member 104. Specifically, the light-blocking member 104 is disposed between the light source 102 and the lens 103. The light-blocking member 104 has a light pattern notch of a preset shape to allow the preset light emitted by the light source 102 to pass through and form a preset light pattern. In this embodiment, the desired light pattern shape can be easily obtained through the preset shape light pattern notch provided on the light-blocking member 104, which has a wide range of application scenarios.

[0057] In some embodiments, the lens 103 provided by the present invention is preferably configured as a plastic structure, made of plastic material. The significance of using plastic material to make the lens 103 is that, since the refractive surface 132 of the lens 103 provided in this embodiment is divided into several adjustment units, and each adjustment unit has a preset radius of curvature, it is not easy to achieve this using other materials such as glass. Using plastic material can reduce production costs and can well ensure the accuracy of light control by each adjustment unit. Based on the embodiment where the lens 103 is made of plastic material, for the purpose of protecting the lens 103, some embodiments preferably also include tempered glass 105. Specifically, tempered glass 105 is disposed at the cavity opening of the lamp tube 101 and is used to seal the cavity to achieve the purpose of protecting the lens 103.

[0058] See Figure 14 In some embodiments, the lamp housing 101 specifically includes a lamp head 111 and a lamp body 112, wherein the lamp head 111 and the lamp body 112 each form a portion of a mounting cavity. The light source 102, lens 103, and light-blocking member 104 are all disposed within the mounting cavity, and the lamp head 111 and the lamp body 112 are sealed together. This structure facilitates the subsequent disassembly and maintenance of the fog lamp provided by the present invention, and the sealed connection between the lamp head 111 and the lamp body 112 enables the automotive headlight to be waterproof. Specifically, the lamp head 111 and the lamp body 112 can be sealed together using sealant.

[0059] In some embodiments, the lamp body 112 is provided with heat dissipation fins for heat dissipation. The heat dissipation fins on the lamp body 112 can effectively dissipate heat from the lamp body 112. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
