[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0039] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.
[0040] As car shapes become more and more complex, the shapes of car lights are also increasingly seeking to be unique. Among them, high-tech lighting effects are gradually becoming the highlight of car lights. In this context, many automotive companies have proposed the concept of fiber optic car lights.
[0041] Fiber optic headlights have optical fibers installed on light guide plates, but currently optical fibers are difficult to install and fix, have high manufacturing costs, and have low luminous efficiency.
[0042] Based on this, the present application discloses a car lamp that realizes the fiber optic effect. A reflective layer is sprayed or printed on the inner wall of the light guide plate, and the luminous layer can fully reflect the light, thereby forming a light effect at the reflective layer. No additional optical fiber is required, which improves the assembly efficiency of the car lamp and reduces the manufacturing cost.
[0043] Combination Figures 1 to 8 The vehicle lamp realizing the optical fiber effect shown includes a light guide plate 60, a reflector and a light source module.
[0044] Among them, the light guide plate 60 is a cylindrical structure, and the inner wall of the light guide plate 60 is sprayed or printed with a reflective layer (not marked in the figure), which can totally reflect the light; the reflector is arranged at the end of the axial direction of the light guide plate 60; the light source module is opposite to the reflector, and the light of the light source module is reflected by the reflector and irradiated on the light guide plate 60.
[0045] The shape and size of the reflective layer on the inner wall of the light guide plate 60 can be set according to different fiber optic effects. In some embodiments, the reflective layer can be a strip structure along the axial direction of the light guide plate 60 to form a corresponding fiber optic effect. The reflector is used to couple the light from the light source module and reflect the light to the light guide plate 60. The light source module includes but is not limited to an LED lamp. The light from the light source module is reflected by the reflector and irradiated onto the light guide plate 60, and the reflective layer on the light guide plate 60 forms the same effect as the light of the fiber optic.
[0046] In the present application, by spraying or printing a reflective layer on the inner wall of the light guide plate 60, the light from the light source module can be reflected by the reflector and then irradiated onto the light guide plate 60, and the reflective layer on the light guide plate 60 forms the same effect as the lighting of the optical fiber. This method does not require the additional arrangement of optical fibers, thereby improving the assembly efficiency of the car lights and reducing the manufacturing cost.
[0047] In some embodiments, the light guide plate 60 is a cylindrical structure, and the diameter in the middle of the cylindrical structure is smaller than the diameters at both ends of the cylindrical structure. The shape and size of the light guide plate 60 in the present application can be set according to different needs, and are all within the scope of protection. This article only exemplifies a cylindrical structure with a gradually increasing diameter from the middle to the two ends.
[0048] Exemplarily, the reflective layer is a strip structure extending along the axis direction of the light guide plate 60 to form a strip optical fiber effect on the light guide plate 60. Of course, the reflective layer includes but is not limited to a strip structure, and reflective layers of other shapes are also within the protection scope.
[0049] In some embodiments, both ends of the light guide plate 60 along the axial direction are provided with a reflector and a light source module. Figures 3 to 5 As shown, the reflector includes a first reflector 21 and a second reflector 22 , and the light source module includes a first light source module 31 and a second light source module 32 .
[0050] In the present application, the upper end of the light guide plate 60 along the axial direction is provided with a second reflector 22 and a second light source module 32, and the second light source module 32 is opposite to the second reflector 22, and the light emitted by the second light source module 32 passes through the second light source module 32 and irradiates the light guide plate 60. The lower end of the light guide plate 60 along the axial direction is provided with a first light source module 31 and a first reflector 21, and the first light source module 31 is opposite to the first reflector 21, and the light emitted by the first light source module 31 passes through the first reflector 21 and irradiates the light guide plate 60. By providing light source modules and reflectors at both the upper and lower ends of the light guide plate 60, the lighting effect of the vehicle lamp can be improved.
[0051] In some embodiments, the first reflector 21 and the second reflector 22 are both circular structures connected to the light guide plate 60, the first light source module 31 is arranged in the middle of the first reflector 21, and the second light source module 32 is arranged in the middle of the second reflector 22. The first light source module 31 and the second light source module 32 are both a group of LED lamps or a single LED lamp, which can reduce the number of LED lamps and save the cost of electronic modules compared to the circumferential arrangement of LED lamps around the light guide plate 60. In addition, reducing the number of LED lamps can effectively reduce the space requirement of the entire lamp, creating favorable conditions for the development of the shape.
[0052] like Figures 5 to 7 As shown, a baffle is provided at the end of the light guide plate 60 , the baffle is opposite to the reflector, and there is a light entrance gap between the baffle and the inner wall of the light guide plate. The light from the light source module passing through the reflector irradiates the inner wall of the light guide plate 60 through the light entrance gap.
[0053] The baffle plate includes a first baffle plate 51 and a second baffle plate 52. The first baffle plate 51 is located at the lower end of the light guide plate 60, and the light emitted by the first light source module 31 can be irradiated to the light guide plate 60 through the light entrance gap between the first baffle plate 51 and the light guide plate 60; the second baffle plate is located at the upper end of the light guide plate 60, and the light emitted by the second light source module 32 can be irradiated to the light guide plate 60 through the light entrance gap between the second baffle plate 52 and the light guide plate 60. The first baffle plate 51 and the second baffle plate 52 can effectively prevent the generation of leakage light.
[0054] By arranging the baffles, the LED bright spots are completely hidden, and the coupling between the light source module and the light guide plate 60 is invisible, creating a sense of mystery and novelty, and achieving the optical fiber lighting effect of suspended three-dimensional lines. The light input method of the light guide plate 60 in this application solves the problem of the long mixing distance of the light guide plate, and can achieve large-area lighting with only a few LEDs, which is low-cost.
[0055] The light guide plate 60 in the present application is provided with a plurality of ridges arranged in the circumferential direction, and the reflective layer is provided on the inner wall of the ridges. The provision of the ridges can make the optical fiber effect obvious after lighting. In some embodiments, a variety of lighting effects can be achieved by adjusting the thickness of the ridges or the density and direction of the lines. This solution can match the modeling features of different sizes and has strong applicability.
[0056] The ridges of the light guide plate 60 may be formed by injection molding, and the shapes of the ridges include but are not limited to linear rounded edges or square edges.
[0057] In some embodiments, the light guide plate 60 includes a first light guide plate 61 and a second light guide plate 62, wherein the cross-sections of the first light guide plate 61 and the second light guide plate 62 are both arc-shaped, that is, semi-cylindrical, and the two are spliced to form a cylindrical structure. Of course, the light guide plate 60 can also be an integrally formed cylindrical structure.
[0058] Figure 8 The first light guide plate 61 has a first ridge 611 on its circumference, and the second light guide plate 62 has a second ridge 621 on its circumference. The shapes of the first ridge 611 and the second ridge 612 can be the same or different. Those skilled in the art can make settings according to different lighting effects, and all are within the scope of protection.
[0059] It should be noted that the reflective layer involved in the present application can be a reflective material such as reflective ink or high-gloss paint, which can form a lighting effect similar to that of optical fiber.
[0060] Figure 7 The reflector shown includes: a focusing light guiding section (not shown in the figure) and a total reflection section (not shown in the figure).
[0061] The focusing light guide section is opposite to the light source module; the total reflection section is in contact with the baffle of the light guide plate 60, and the baffle can be used to block the light at the total reflection section, so that the light can only pass through the preset position. The total reflection section has a reflection surface that is inclined relative to the focusing light guide section, and the reflection surface is used to reflect the light of the focusing light guide section to the light guide plate 60.
[0062] The focusing light guide section of the reflector in the present application can focus light on the light source module, and use the reflection surface of the total reflection section to reflect the light, so that the light is reflected along a preset path. The reflector has a simple structure and good luminous effect, and can achieve the effect of uniform luminescence of the light guide plate.
[0063] In some embodiments, there are two total reflection segments, and they are arranged about the light-concentrating light guide segment, and the reflection surfaces of the two total reflection segments are inclined toward the inner wall of the light guide plate 60 on the corresponding side, forming Figure 6 The triangle position between the first baffle 51 and the first reflector 21. It should be noted that the total reflection section can be a circular structure, and the focusing light guide section is arranged in the middle position of the total reflection section to make the circumferential light emission of the light guide plate 60 uniform.
[0064] It should be noted that when there is at least one light guide plate 60 , and when there are at least two light guide plates 60 , the light guide plates 60 are nested and arranged to achieve more levels of floating line lighting effects.
[0065] In addition, the present application also discloses a vehicle, including a headlight, wherein the headlight is the headlight for realizing the fiber optic effect disclosed in the above embodiment. Therefore, the vehicle with the headlight for realizing the fiber optic effect also has all the above technical effects, which will not be repeated here one by one.
[0066] Combination Figure 1 As shown, the two ends of the light guide plate 60 are fixedly connected to the PCB through the first cover plate 41 and the second cover plate 42 respectively. The first cover plate 41 and the second cover plate 42 can be made of white diffuse reflection (including but not limited to aluminum plating) materials to increase optical utilization. The two ends of the light guide plate 60 are fixed to the lamp housing through the first decorative frame 11 and the second decorative frame 12 respectively.
[0067] Specifically, the first cover plate 41 is covered on the outside of the first reflector 21, the second cover plate 42 is covered on the outside of the second reflector 22, and the first decorative frame 11 and the second decorative frame 12 respectively fix the upper and lower ends of the light guide plate 60 to the housing of the vehicle lamp. The fixing method of the light guide plate 60 in the present application is compact in structure, and the installation and positioning structure is ingenious, which effectively reduces the space requirement for the entire lamp.
[0068] The headlights in this application are completely mass-producible, can achieve richer effects, higher efficiency, and better uniformity, and greatly reduce production and R&D costs.
[0069] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0070] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
