Description
Technical Field
[0001] This utility model relates to the field of automotive lighting technology, and in particular to a headlight module with fog lights. Background Technology
[0002] As a modern and convenient means of transportation, automobiles have become an indispensable part of people's daily lives and work. To improve driving safety, various lights with different functions are installed at the front and rear of vehicles. These include low beam headlights, which illuminate the road and surrounding environment, allowing drivers to clearly see the road conditions at close range; high beam headlights, which focus light on the distant environment, helping drivers see further roads and obstacles; and fog lights, which improve vehicle visibility in adverse weather conditions, helping drivers maintain a clear field of vision. Fog lights are characterized by high brightness and penetrating power, enabling drivers to see the road ahead clearly in foggy, rainy, and poor visibility conditions.
[0003] Because different types of vehicle lights have their own design considerations, they are not interchangeable. To improve vehicle safety, there has been a trend towards integrated headlight designs in recent years. However, current integrated headlight designs often increase the size of the headlight to accommodate multiple different types of light sources, resulting in large headlights that occupy a lot of space and are not conducive to installation on automobiles.
[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0035] This utility model provides a vehicle light module with fog lights. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0036] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," and "rear," etc., indicating orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.
[0037] In this invention, the terms "cut-off line," "low beam 75R," and "low beam three zones" are well-known to those skilled in the art. The cut-off line refers to a clear boundary between light and dark areas formed by a car headlight (especially a low beam) during illumination, ensuring the driver can clearly see the road ahead while avoiding glare for oncoming vehicles. The low beam 75R refers to the illuminance value or illumination effect at a specific angle (usually the right side of 75 degrees) within the low beam's illumination range; it is one of the important indicators for evaluating the lighting effect and performance of a car's low beam headlights. The low beam three zones, located after the cut-off line, have relatively weaker light, forming a dark zone (anti-glare zone), mainly used to illuminate the distant road surface and road edges in front of the vehicle, and to reduce glare interference for drivers of oncoming vehicles.
[0038] In this invention, a1 represents the low beam ray that forms the cutoff line between light and dark, a2 represents the low beam ray that increases the luminous efficacy of the 75R zone of the low beam, a3 represents the low beam ray that forms the three zones of the low beam, b represents the high beam ray, and c represents the fog light ray. "Front" indicates the light emission direction of the headlight module, and "front" is opposite to "rear".
[0039] Please see Figures 1 to 10 As shown, this utility model provides a vehicle light module with fog lights, including a housing 1, a heat dissipation bracket 3, a gate-shaped bracket 7, a fog light source plate 8, and a fog light reflector 82; a lens 2 is provided at the front end of the housing 1; the heat dissipation bracket 3 is disposed inside the housing 1; a low beam source plate 4 and a low beam reflector 41 are provided on the upper surface of the heat dissipation bracket 3, the low beam reflector 41 is used to reflect the low beam light emitted by the low beam source plate 4; a high beam source plate 5 and a light guide 6 are provided at the front end of the heat dissipation bracket 3, the light guide 6 is used to guide the high beam light emitted by the high beam source plate 5; the gate-shaped bracket 7 is disposed on the heat dissipation bracket 3 and located above the light guide 6; A fog light source plate 8 is disposed on the upper surface of the portal bracket 7, and a first LED chip lamp bead 81 is disposed on the fog light source plate 8; a fog light reflector 82 is disposed on the upper surface of the portal bracket 7 and is used to reflect the fog light emitted by the first LED chip lamp bead 81; a fog light lens 21 is disposed on the lens 2 corresponding to the position of the fog light reflector 82, and the fog light lens 21 is used to refract the fog light reflected by the fog light reflector 82 and then emit light; a mounting part 821 is disposed at the front end of the fog light reflector 82, the mounting part 821 is located in front of the fog light source plate 8, and the upper surface of the mounting part 821 has a first reflective layer 822.
[0040] In the above description, the low beam light source board 4 is equipped with a second LED SMD lamp 42, which emits low beam light. The high beam light source board 5 is equipped with a third LED SMD lamp 51, which emits high beam light.
[0041] like Figure 8 As shown, when using low beam, the second LED chip lamp 42 on the low beam light source board 4 emits low beam light. The low beam light is reflected by the low beam reflector 41 and the light guide 6 and then reaches the lens 2. The lens 2 refracts the low beam light and emits it to form a clear cutoff line between light and dark, thus meeting the requirements for low beam use.
[0042] like Figure 9 As shown, when using the high beam, the second LED chip lamp 42 on the low beam light source board 4 emits low beam light, and the third LED chip lamp 51 on the high beam light source board 5 emits high beam light. The high beam light forms a light pattern with a certain shape under the action of the light guide 6, and is then refracted by the lens 2 before being emitted, so that the high beam light can illuminate a farther distance and meet the needs of high beam use.
[0043] like Figure 10As shown, when the fog lights are in use, the first LED chip lamp 81 on the fog light source board 8 emits fog light rays. Part of the fog light rays are reflected by the fog light reflector 82 and reach the fog light lens 21. Another part of the fog light rays are reflected by the fog light reflector 82 to the first reflective layer 822, and after secondary reflection by the first light-emitting layer, they reach the fog light lens 21. The fog light lens 21 refracts the fog light rays and emits them, meeting the usage requirements of the fog lights. By setting the fog light reflector 82 and the first reflective layer 822, most of the fog light rays can be reflected onto the fog light lens 21, effectively reducing fog light loss.
[0044] In the above, by setting a door-shaped bracket 7 on the heat dissipation bracket 3 to install the fog light source plate 8, compared with the existing technology, it is not necessary to increase the volume of the housing 1 to enable the vehicle light module to have the function of turning on the fog lights, which can meet the user's needs.
[0045] In the above, the lens 2 is preferably a plano-convex lens, and the fog light lens 21 is preferably a convex lens, so as to achieve the function of focusing the low beam, high beam and fog light.
[0046] In a preferred embodiment, see [reference] Figure 4 , 5 The front end of the mounting part 821 is provided with a first arc-shaped notch 823. The first arc-shaped notch 823 is used to avoid part of the fog light reflected by the fog light reflector 82. This part of the fog light passes through the first arc-shaped notch 823 and directly enters the fog light lens 21 for refraction, so that the fog light output is uniform.
[0047] In a preferred embodiment, see [reference] Figure 5 The mounting part 821 has several positioning posts 824 at its bottom, and the portal bracket 7 has several positioning holes 71, into which the positioning posts 824 can be inserted. This design allows for quick positioning and installation of the fog light reflector 82, facilitating the assembly of the vehicle light module. Specifically, the mounting part 821 and the fog light reflector 82 are integrally formed and are stably mounted on the portal bracket 7 using screws.
[0048] In a preferred embodiment, see [reference] Figure 3The system also includes a laser light 9, which is mounted on the portal frame 7. The lens 2 has a laser lens 22 corresponding to the position of the laser light 9. The laser lens 22 refracts the laser light emitted by the laser light 9 before outputting the light. This configuration enables the vehicle headlight module to activate the laser light 9, emitting brighter light with stronger penetrating power, providing better illumination for the driver, especially in adverse weather conditions such as rain, fog, and sandstorms. Similarly, by adding the laser light 9 to the portal frame 7, compared to existing technologies, the volume of the housing 1 is not increased to enable the vehicle headlight module to activate the laser light 9, thus meeting user needs.
[0049] In the above, the laser lens 22 is preferably a convex lens to focus the laser beam.
[0050] Furthermore, there are two laser lights 9, symmetrically arranged on both sides of the fog light source plate 8. The laser lights 9 are horizontally positioned, and the laser light emitted is directly refracted by the laser lens 22 to form a more penetrating light, which can further help the driver see the road ahead. The gantry bracket 7 includes two symmetrically arranged support arms 72 and a crossbeam 73 for connecting the two support arms 72; the top of the support arms 72 and the end of the crossbeam 73 are respectively provided with semi-circular grooves 721 for installing the laser lights 9; the fog light source plate 8 is located in the middle of the crossbeam 73. Through the above arrangement, the fog light source plate 8 and the two laser lights 9 are stably installed.
[0051] Preferably, the crossbeam 73 and the support arm 72 are quickly positioned and installed through the cooperation of positioning holes and positioning posts, and the position of the crossbeam 73 is locked by screws. The fog light source plate 8 and the crossbeam 73 are quickly positioned and installed through the cooperation of positioning holes and positioning posts, and the position of the fog light source plate 8 is locked by screws.
[0052] Furthermore, see Figure 4 , 5 The two support arms 72 and the heat dissipation bracket 3 are integrally formed to improve the heat dissipation efficiency of the laser lamp 9 and the fog light source plate 8.
[0053] Furthermore, see Figure 5 A limiting block 731 is provided at the rear end of the semicircular groove 721 of the crossbeam 73. The two semicircular grooves 721 form a circular slot to facilitate the installation of the laser lamp 9. By setting the limiting block 731, the laser lamp 9 can be prevented from moving backward and dislodging from the circular slot. It should be understood that the laser lamp 9 is connected to a wire. Under the pull of the wire, the laser lamp 9 will not move forward, thus ensuring the stability of the laser lamp 9 installation.
[0054] In a preferred embodiment, see [reference] Figure 6, an annular groove 11 is provided at the front end of the housing 1, a flange 23 mating with the annular groove 11 is provided on the lens 2, a positioning groove 24 is formed on the flange 23, and a positioning block 12 matching the positioning groove 24 is provided in the annular groove 11. By providing the cooperation of the annular groove 11 and the flange 23 to limit the axial movement of the lens 2, and the cooperation of the positioning groove 24 and the positioning block 12 to limit the axial movement of the lens 2, the position correspondence between the fog lamp lens 21 and the fog lamp reflector 82, and between the laser lens 22 and the laser lamp 9 is ensured.
[0055] In a preferred embodiment, referring to Figure 7 , one or more light guiding portions 61 are provided at the rear end of the light guide 6, a second arc-shaped notch 62 is provided at the front end of the light guide 6, the second arc-shaped notch 62 is used to avoid part of the light emitted by the low beam light source board 4, an arc-shaped light emitting surface 63 is formed at the edge of the second arc-shaped notch 62, the light guiding portions 61 guide the light emitted by the high beam light source board 5 to the arc-shaped light emitting surface 63 for light emission, a second reflective layer 64 is provided on the upper surface of the light guide 6, and the second reflective layer 64 includes a reflective plane 641 which is used to reflect part of the light emitted by the low beam light source board 4 to form a clear cut-off line between light and darkness.
[0056] As Figure 8 shown, when using the low beam, the low beam light source board 4 emits low beam light rays, all the low beam light rays are reflected by the low beam reflector 41, most of the low beam light rays after one reflection pass through the first arc-shaped notch 823 and reach the lens 2, the lens 2 condenses and emits this part of the low beam light rays, a small part of the low beam light rays reaches the reflective plane 641 for secondary reflection, the reflective plane 641 reflects this part of the low beam light rays to the lens 2, and this part of the low beam light rays undergoes total internal reflection in the lens 2 and finally returns or disappears, so that a clear cut-off line between light and darkness is formed after the low beam light rays are emitted, to meet the usage requirements of the low beam. By providing the light guide 6, the volume of the vehicle lamp module can be effectively reduced.
[0057] Preferably, there are three light guiding portions 61, the three light guiding portions 61 are arranged in a "pin" shape structure, and one third LED chip lamp bead 51 corresponds to one light guiding portion 61 to improve the brightness of the high beam, and the light rays emitted by the three third LED chip lamp beads 51 do not interfere with each other.
[0058] As Figure 9 shown, when using the high beam, the low beam light source board 4 and the high beam light source board 5 emit light, the high beam light rays emitted by the high beam light source board 5 enter the light guide 6 through the light guiding portions 61, the high beam light rays undergo total internal reflection in the light guide 6, and finally enter the lens 2 from the arc-shaped light emitting surface 63, the lens 2 condenses and emits the high beam light rays, and the light guide 6 converges the high beam light rays into a light emitting light shape with a certain shape to improve the effect of irradiating a farther distance.
[0059] In the above description, the light guide is made of transparent materials such as PMMA, PC, and PS to ensure stable and efficient light transmission. The first reflective layer 822 and the second reflective layer 64 can be made of aluminum-plated film, reflective aluminum foil, or reflective sheet material to enable the upper surface of the light guide 6 and the mounting part 821 to reflect light.
[0060] In a preferred embodiment, see [reference] Figure 7 , 9 The reflective layer also includes a reflective slope 642, which is connected to the reflective plane 641. The reflective slope 642 is inclined upward along the light emission direction of the high beam light source plate 5. The reflective slope 642 is used to reflect part of the light emitted by the low beam light source plate 4 to enhance the luminous flux in the low beam 75R region. When the low beam is emitted, part of the low beam light emitted by the low beam light source plate 4 is reflected by the low beam reflector 41 to the reflective slope 642. The reflective slope 642 reflects this part of the light to the lens 2, and finally it is emitted after being refracted by the lens 2, thereby enhancing the luminous flux in the low beam 75R region, that is, improving the light efficiency in the bright area below the cutoff line. By setting the reflective slope 642, part of the low beam light that cannot pass smoothly through the notch to reach the lens 2 can be effectively utilized, thereby improving the utilization rate of the light emitted by the low beam light source plate 4.
[0061] In the above description, the reflecting plane 641 is a plane that is nearly parallel to the horizontal plane, or a plane with a small angle to the horizontal plane; the slope of the reflecting inclined plane 642 is greater than the slope of the reflecting plane 641. In practical applications, the tilt angles of the reflecting plane 641 and the reflecting inclined plane 642 should be determined according to actual usage requirements, and their specific tilt angles are not limited here.
[0062] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
