[0002] In the field of vehicle lighting, the performance of high beams has a vital impact on vehicle driving safety and driving experience. With the continuous development of automobile technology, people's requirements for high beams are also increasing. Traditional high beam lighting systems often have problems with less than ideal light distribution, resulting in poor lighting effects. In particular, in some traditional high beam devices, light is prone to scattering and loss during propagation, and the light cannot be effectively concentrated and projected to a distance, thus affecting the driver's observation of distant roads and obstacles at night or in low visibility conditions. In addition, the heat dissipation performance of traditional high beam lighting systems is also poor. After long-term use, heat accumulation may also affect the performance and life of the lamp.

The light is then guided by the light-guiding portion and enters the hemispherical protrusion and then emitted in parallel to form a high beam.

[0009] As a preferred solution of the vehicle lamp of the present invention, the components of the light guide body are: 60%-70% methyl vinyl silicone rubber, 20%-30% fumed silica, 5%-10% alumina, 0.5%-1.5% hindered phenol antioxidant, and 0.5%-1.5% benzotriazole ultraviolet absorber.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1) The light guide body of the high beam light guide of the present invention is integrally injection molded from silicone material. The silicone material has good flexibility and formability. The funnel-shaped cavity of the light inlet portion is combined with the convex light inlet protrusion, which can effectively collect light and allow as much light as possible to enter the light guide. The light guide portion adopts a columnar silicone rod to provide a stable channel for the conduction of light. The hemispherical protrusion design of the light outlet portion allows the light collected and conducted by the light guide portion to be emitted in parallel, thereby achieving a good high beam lighting effect, greatly improving the efficiency of light utilization, and enhancing the lighting ability of the high beam at night or under low visibility conditions, providing the driver with a clearer and farther field of vision. At the same time, the present invention uses a specific silicone component ratio to make the light guide have a suitable refractive index, which can effectively guide the light to propagate inside, reduce light loss, and avoid yellowing or aging. At the same time, silicone can be quickly made into light guides of suitable sizes through injection molding, ejection and other molding methods, which can achieve large-scale production to improve efficiency and reduce costs;

[0017] 2) When installing the high beam light guide of the present invention, the installation sleeve is sleeved on the outside of the light guide part, and the plug-in strips on both sides cooperate with the snap-in grooves on the lamp housing. The light guide is firmly installed through the snap-in of the arc grooves and the arc protrusions. The metal installation sleeve is made of metal and coated with a carbon black coating on the inside. The metal properties are used to help the light-emitting part to dissipate heat. The carbon black coating can not only increase the thermal conductivity of the installation sleeve, but also the black coating is conducive to absorbing and dissipating heat. The hollow interlayer and honeycomb partitions arranged in the heat-conducting mechanism can further improve the heat dissipation efficiency by filling helium, and can promptly dissipate the heat generated by the light guide during operation, avoiding the influence of heat accumulation on the performance of the light guide and the entire vehicle lamp, and helping to improve the overall stability and service life of the vehicle lamp. At the same time, the honeycomb partitions provided can effectively reduce the overall weight of the installation structure while ensuring the structural strength of the installation sleeve, thereby providing technical support for lightweight vehicle lamps.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "set" should be understood in a broad sense, for example, they can be fixedly connected or set, or detachably connected or set, or integrally connected or set. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Reference Figures 1 to 11 A high beam light guide, comprising a light guide body 100, the light guide body 100 is integrally injection-molded from a silicone material, the light guide body 100 comprises a light inlet portion 110 disposed at one end, a light outlet portion 120 is disposed at the other end of the light guide body 100, a light guide portion 130 is disposed between the light inlet portion 110 and the light outlet portion 120, and the light guide portion 130 is a columnar silicone rod;

[0035] The light inlet portion 110 includes a funnel-shaped cavity 131 located at one end of the light guide portion 130 , a convex light inlet protrusion 132 is fixedly connected to the bottom of the funnel-shaped cavity 131 , and the light outlet portion 120 is a hemispherical protrusion 121 fixedly connected to the other end of the light guide portion 130 .

[0036] Specifically, the light guide body 100 is integrally injection-molded from a silicone material. The soft properties of the silicone material enable the light guide to adapt to different installation environments and usage requirements, while the moldability ensures that complex structures such as the light inlet portion 110, the light guide portion 130 and the light outlet portion 120 can be precisely molded. The funnel-shaped cavity 131 at one end of the light inlet portion 110 can collect as much light from the light source as possible. The convex light inlet protrusion 132 is located at the bottom of the funnel-shaped cavity 131, which can focus and guide the incoming light, so that the light enters the light guide body 100 more concentratedly. The light guide portion 130 of the columnar silicone rod provides a stable and regular channel for light conduction, thereby reducing the scattering of light during the conduction process. When the light is collected and conducted by the light guide portion 130, the hemispherical protrusion 121 of the light outlet portion 120 can refract the light, thereby emitting it in parallel. The parallel emitted light can form a clear lighting area in the distance, thereby greatly improving the light utilization efficiency and achieving a good high-beam lighting effect (refer to Fig. 9 and Fig.10 ).

[0037] In this embodiment, the diameter of one end of the light guide portion 130 is 15 mm, and the bottom diameter of the light input portion 110 is the same as the diameter of one end of the light guide portion 130; the diameter of the other end of the light guide portion 130 is 14 mm, and the bottom diameter of the light output portion 120 is the same as the diameter of the other end of the light guide portion 130.

[0038] Specifically, when the light enters the light guide portion 130 from the light inlet portion 110, the diameter of 15 mm can ensure that there is enough space for the light to be initially adjusted and gathered when entering, thereby avoiding excessive scattering of the light at the entrance. As the light is transmitted in the light guide portion 130, the diameter gradually changes to 14 mm. The gradually changing diameter helps the light to form a suitable propagation path inside the light guide portion 130, so that the light can be transmitted to the light output portion 120 in a more orderly manner. When the light reaches the light output portion 120, the design with the same diameter as the bottom of the light output portion 120 ensures that the light can smoothly enter the light output portion 120 and be emitted in parallel from the light output portion 120 in an expected manner, thereby achieving a good high beam effect.

[0039] In this embodiment, the center lines of the light-incoming protrusion 132 and the hemispherical protrusion 121 coincide with the center line of the light-guiding portion 130 and are located on the same straight line.

[0040] Specifically, when the light enters the light input portion 110, the light input protrusion 132 is located on the center line of the light guide portion 130, so that the light can be guided to the center position of the light guide portion 130 in a centrally symmetrical manner and gathered, which can minimize the loss of light in the gathering process. After the light is transmitted through the light guide portion 130, it reaches the hemispherical protrusion 121 of the light output portion 120. Since the center line of the hemispherical protrusion 121 also coincides with the light guide portion 130, the light can be accurately emitted from the hemispherical protrusion 121 in parallel along this straight line, thereby improving the effect of the high beam lighting and ensuring that a clear and concentrated lighting area is formed in the distance.

[0041] In this embodiment, when light enters the funnel-shaped cavity 131, it is collected by the light-guiding portion 130, and the intersection of the collected light is located at the center of the light-guiding portion 130. The light is then guided by the light-guiding portion 130 and enters the hemispherical protrusion 121 and then emitted in parallel to form a high beam.

[0042] Specifically, during the light transmission process, the silicone material inside the light guide portion 130 and its columnar structure work together to reduce the scattering and loss of light. When the light is transmitted through the light guide portion 130 and enters the hemispherical protrusion 121, the curved surface structure of the hemispherical protrusion 121 will refract the light. According to optical principles, refraction can adjust the light to a state of parallel emission, ultimately forming a high beam. The light guide component realizes the collection, convergence, and transmission of light to the final parallel emission. The various structures work closely together to meet the needs of high beam lighting.

[0043] In this embodiment, the components of the light guide body 100 are: 60%-70% methyl vinyl silicone rubber, 20%-30% fumed silica, 5%-10% aluminum oxide, 0.5%-1.5% hindered phenol antioxidant, and 0.5%-1.5% benzotriazole ultraviolet absorber.

[0044] Specifically, the light guide body 100 uses methyl vinyl silicone rubber as the main component, and utilizes its flexibility and formability to provide a basis for the manufacture of the light guide, so that the light guide can be injection molded into various complex shapes, and can adapt to different stress environments during use without being easily damaged. The fumed silica component plays an important role in adjusting the refractive index in the light guide. By adding it in a reasonable proportion, the light can be propagated along the expected path inside the light guide, reducing the refraction loss of the light during the propagation process; the aluminum oxide component has a high thermal conductivity, which can generate heat generated by the light guide during operation. The heat can be effectively conducted away to prevent the influence of heat accumulation on the performance of the light guide; the hindered phenol antioxidant component can prevent the light guide from oxidizing during long-term use and avoid aging of the light guide, thereby extending the service life of the light guide; the benzotriazole ultraviolet absorber component can absorb ultraviolet rays and effectively prevent ultraviolet rays from damaging the material of the light guide and affecting its optical properties. It can also resist the erosion of ultraviolet rays and ensure the normal operation of the light guide; through the specific component ratio, the light guide has a suitable refractive index, effectively guides the light to propagate inside, reduces light loss, and avoids yellowing or aging.

[0045] A mounting structure for a high beam light guide, used for mounting any high beam light guide of the skilled person, further comprising a mounting sleeve 200 sleeved on the outside of a light guide portion 130, plug strips 210 being fixedly connected on both sides of the mounting sleeve 200, an arc-shaped plug section 211 being provided at one end of the plug strip 210, two groups of arc-shaped grooves 212 being provided on both sides of the plug strip 210, the length and shape of the mounting sleeve 200 being matched with the length and shape of the light guide portion 130, and a heat conduction mechanism 220 being provided inside the mounting sleeve 200.

[0046] Specifically, when the light guide body 100 and the installation sleeve 200 are plugged and installed, the arc-shaped plug-in portion 211 can be more easily inserted into the clamping groove 311 on the lamp housing 300, reducing the resistance during the installation process. The arc-shaped grooves 212 on both sides of the plug-in strip 210 are clamped with the arc-shaped protrusions 312 in the clamping groove 311, and the clamping method can provide a stable connection to prevent the installation sleeve 200 from loosening or displacement during use; and the length and shape of the installation sleeve 200 are adapted to the light guide 130, ensuring that the installation sleeve 200 can fully cover the light guide 130, which can not only achieve better heat dissipation effects, but also improve the stability of the installation; the heat conduction mechanism 220 is set to effectively dissipate the heat conducted by the light guide 130, ensuring the stability of the light guide during operation, and ensuring the normal realization of the high beam lighting function.

[0047] In this embodiment, the installation sleeve 200 is made of metal material, the inner side of the installation sleeve 200 is tightly fitted with the light guide portion 130 , and the inner side of the installation sleeve 200 is also coated with a black carbon black coating 230 .

[0048] Specifically, during the operation of the light guide, since the inner side of the mounting sleeve 200 is in close contact with the light guide portion 130, the heat collected by the light guide portion 130 can be transferred to the mounting sleeve 200 by heat conduction. The black carbon black coating 230 on the inner side of the mounting sleeve 200 can increase the thermal conductivity of the mounting sleeve 200 and improve the efficiency of heat conduction from the light guide portion 130 to the mounting sleeve 200, thereby ensuring that the temperature of the light guide will not be too high during operation, thereby improving the working efficiency and service life of the light guide.

[0049] In this embodiment, the heat conduction mechanism 220 includes a hollow interlayer 221 located inside the installation sleeve 200 , a partition plate 222 with a honeycomb cross-section is fixedly connected inside the hollow interlayer 221 , and the hollow interlayer 221 is also filled with helium.

[0050] Specifically, when the heat of the light guide part 130 is conducted to the mounting sleeve 200, the hollow interlayer 221 can accommodate the heat and provide a path for further heat conduction, and the filled helium can quickly spread the heat in the interlayer and dissipate it through the surface of the mounting sleeve 200, thereby further improving the heat dissipation efficiency, timely dissipating the heat generated during the operation of the light guide, and ensuring the normal operation of the light guide and the entire headlight; and the partition 222 with a honeycomb-shaped cross-section can not only ensure the structural strength of the mounting sleeve 200, but also reduce the overall weight, thereby achieving lightweight headlights.

[0051] A vehicle lamp, a lamp body formed by installing any of the above-mentioned high-beam light guides through any of the above-mentioned installation structures in the claims, further comprising a lamp housing 300, a surface of the lamp housing 300 being provided with a plurality of installation cavities 310 for fitting a mounting sleeve 200, an inner side of the installation cavity 310 being further provided with a snap-in groove 311 for snap-in to a connector strip 210, an inner side of the snap-in groove 311 being further fixedly connected with an arc-shaped protrusion 312 adapted to the arc-shaped groove 212, a back side of the lamp housing 300 being further fixedly connected with a back plate 320, an inner side of the back plate 320 being fixedly connected with a lamp board 330, a surface of the lamp board 330 being integrated with a plurality of light-emitting lamp beads 331, and light-emitting ends of the light-emitting lamp beads 331 being placed inside relatively positioned funnel-shaped cavities 131.

[0052] Specifically, the installation cavity 310 provided in the lamp housing 300 matches the installation sleeve 200, so that the installation sleeve 200 can be accurately placed in the installation cavity 310, and is snap-fitted with the plug-in strips 210 on both sides of the installation sleeve 200 through the snap-fitting grooves 311. The snap-fitting method can ensure that the installation sleeve 200 is firmly installed in the installation cavity 310. When the plug-in strip 210 is inserted into the snap-fitting groove 311, the arc-shaped protrusion 312 will be snapped into the arc-shaped groove 212, effectively preventing the installation sleeve 200 from being displaced in the horizontal and vertical directions, thereby ensuring the firmness of the installation of the high beam light guide on the lamp housing 300. The light-emitting end of the light-emitting lamp bead 331 integrated on the surface of the lamp board 330 is placed inside the funnel-shaped cavity 131, ensuring that the light emitted by the light-emitting lamp bead 331 can accurately enter the light inlet portion 110, and form a high beam after being conducted by the light guide, thereby realizing the high beam lighting function of the entire vehicle lamp, greatly improving the utilization efficiency of light, and enhancing the lighting ability of the high beam lamp at night or in low visibility conditions, providing the driver with a clearer and farther field of vision (refer to Fig.11 ).

[0053] It should be noted that the plug-in strip 210 has a certain degree of deformation capability to ensure that the plug-in strip 210 can be smoothly inserted into the card slot 311 .

[0054] In this embodiment, mounting ears 340 are fixedly connected to both sides of the lamp housing 300 , and a plurality of mounting holes 341 are formed on the surface of the mounting ears 340 .

[0055] Specifically, when installing the headlight, the headlight can be firmly mounted on the vehicle by passing bolts through the mounting holes 341; and the multiple mounting holes 341 also increase the flexibility of installation, and a suitable installation method can be selected according to the specific structure and installation requirements of the vehicle to ensure that the headlight can be stably fixed on the vehicle.

[0056] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
