[0037] Reference Figures 1 to 5 , shows a schematic structural diagram of a thick-walled light guide structure according to an embodiment of the present application applied to a vehicle lamp, wherein the thick-walled light guide structure may specifically include: a thick-walled body 10, wherein the thick-walled body 10 includes an arc-shaped light incident surface 11 and an arc-shaped light emitting surface 12 that are arranged opposite to each other;
[0038] The light incident surface 11 is provided with a light guiding surface 14, and the light guiding surface 14 is arranged to be inclined relative to a preset reference surface, and the preset reference surface is perpendicular to the direction of the optical axis of the incident light;
[0039] The curvature of the light emitting surface 12 is a gradual curvature, and the inclination angle of the light guiding surface 14 is positively correlated with the curvature of the light emitting surface 12 corresponding to the light guiding surface 14 .
[0040] In the embodiment of the present application, the thick-walled body 10 can generally be a plate structure, and light enters from the light incident surface 11 and then exits from the light exiting surface 12. A microstructure with an inclined light guiding surface 14 is arranged on the light incident surface 11, so that the microstructure on the light guiding unit 13 forms a structure similar to a collimating structure through the light guiding surface 14 and the light exiting surface 12. When the incident light enters from the light incident surface 11, the refraction of the light guiding surface 14 on the microstructure can alleviate the refraction of the incident light at a larger angle offset caused by the position of the light incident surface 11 with a larger curvature, so that more incident light can be aligned relative to the light exiting surface 12 and then exit from the light exiting surface 12, so that the light intensity and brightness transition of the exiting light is relatively smooth, thereby improving the light exiting effect of the exiting light and reducing the light exiting granular effect produced at the position with a larger curvature on the thick-walled body 10. In this way, there is no need to set an optical pattern on the light-emitting surface 12 of the thick-walled light-guiding structure, making its shape relatively simple, and there is no need to strictly anchor the light-guiding surface 14 in the direction of the demolding, which simplifies the difficulty of opening the mold of the thick-walled light-guiding structure, facilitates demolding, and reduces production costs. In the embodiment of the present application, the inclination angle of the light-guiding surface 14 relative to the preset reference surface can be flexibly adjusted according to the curvature change of the light-emitting surface 12 to adapt to a variety of thick-walled bodies 10 of different shapes, and the compatibility of the thick-walled light-guiding structure is also improved.
[0041] Specifically, in the embodiment of the present application, the light incident surface 11 may be composed of a plurality of planes in sections, and the plurality of planes in sections form an arc or an approximately arc-shaped shape. The light incident surface 11 is provided with a light guiding unit 13, and the light guiding unit 13 includes a plurality of microstructures, and the microstructure is provided with a light guiding surface 14, that is, the light guiding unit 13 has a plurality of light guiding surfaces 14, and the plurality of light guiding surfaces 14 form a step structure. The inclination angle of the light guiding surface 14 is positively correlated with the curvature of the light emitting surface 12 corresponding to the position of the microstructure, that is, the inclination angle of the light guiding surface 14 is set in accordance with the shape of the light emitting surface 12, so that the light emitting surface 12 and the light guiding surface 14 form a similar collimation structure, so that the light emitting surface 12 has a better light emitting effect on the light.
[0042] Compared with the prior art, the step surface of the step structure is usually arranged perpendicularly to the optical axis of the incident light. When the light propagates to the light-emitting surface 12, an optical pattern needs to be arranged on the light-emitting surface 12 so that the light emitted from the light-emitting surface 12 is refracted at a smaller angle. Compared with another prior art, the scheme of removing the optical pattern of the light-emitting surface 12 of the thick-walled body 10, due to the strip-shaped plate structure of the thick-walled body 10, it has an optical waveguide effect in a non-light-emitting direction, so that part of the incident light is totally reflected to the position with a smaller curvature of the light-emitting surface 12 due to the waveguide effect, and a larger light-dark transition or even a bright spot is formed at the corresponding position, making it difficult to achieve a better optimization of the defective position in the light-emitting effect from the structural point of view. In the embodiment of the present application, the inclination angle of the light-guiding surface 14 is positively correlated with the curvature of the light-emitting surface 12 corresponding to the position of the microstructure, so that the light emitted from the light-emitting surface 12 is refracted at a smaller angle, and has a better light-emitting effect, so there is no need to arrange an optical pattern on the light-emitting surface 12, which reduces the demolding difficulty of the thick-walled body 10.
[0043] In the embodiment of the present application, specifically, the light guide surface 14 is tilted relative to the preset plane perpendicular to the direction of the optical axis of the incident light. The curvature of the light emitting surface 12 is a gradual curvature, and the inclination angle of the light guide surface 14 on the microstructure is positively correlated with the curvature of the light emitting surface 12 corresponding to the position of the microstructure, that is, when the curvature of the light emitting surface 12 gradually increases, the inclination angle of the light guide surface 14 on the microstructure gradually increases; when the curvature of the light emitting surface 12 gradually decreases, the inclination angle of the light guide surface 14 on the microstructure gradually decreases.
[0044] Optionally, in the embodiment of the present application, the light emitting surface 12 includes a first end 15 and a second end 16 which are arranged away from each other, and the curvature of the light emitting surface 12 gradually decreases along the direction from the first end 15 to the second end 16, and the inclination angle of the light guiding surface 14 gradually increases. For example, when the curvature of the light emitting surface 12 gradually decreases along the direction from the first end 15 to the second end 16, the inclination angle of the light guiding surface 14 is gradually increased as the curvature of the light emitting surface 12 decreases, so that the inclination angle of the light guiding surface 14 is arranged in accordance with the curvature change of the light emitting surface 12, so that more incident light rays can be aligned relative to the light emitting surface 12, and the refraction of the incident light rays caused by the position of the light incident surface 11 with a larger curvature is alleviated, so as to achieve a better light emitting effect.
[0045] Optionally, in the embodiment of the present application, the light incident surface 11 includes a plurality of microstructures, the microstructures are provided with a light guiding surface 14, and two adjacent microstructures are connected among the plurality of microstructures, and the microstructures are provided with a connecting surface 17, and the connecting surface 17 is connected between two adjacent light guiding surfaces 14. In this way, a relatively stable and reliable connection between adjacent light guiding surfaces 14 is achieved through the connecting surface 17, so that the microstructure forms a relatively stable step structure.
[0046] In the embodiment of the present application, optionally, an arc-shaped transition portion is provided between the connecting surface 17 and the light-guiding surface 14, so that the light-guiding surface 14 smoothly transitions to the connecting surface 17. In this way, the connecting surface 17 is prevented from affecting the light emission effect, and the angle structure formed between the connecting surface 17 and the light-guiding surface 14 to cause refraction loss of the light is also avoided.
[0047] Optionally, in the embodiment of the present application, a frosted structure is provided on the surface of the light guide surface 14. In this way, by frosting the surface of the light guide surface 14 to form a frosted structure, the influence of the connecting surface 17 between adjacent light guide surfaces 14 on the emission effect of light can also be reduced, so that the incident light is diffusely scattered on the light guide surface 14, and part of the light refracted by the connecting surface 17 is recovered, thereby reducing the light loss caused by the refraction of the light by the connecting surface 17.
[0048] For example, in an embodiment of the present application, the width of the light-guiding surface 14 can be set to be smaller, so as to further reduce the height difference between the light-guiding surfaces 14 to improve the aesthetics, and also make the size of the light-guiding surface 14 much larger than the size of the optical pattern, which facilitates the film opening of the thick-walled light-guiding structure and reduces the manufacturing difficulty.
[0049] Optionally, in the embodiment of the present application, the thickness of the thick-walled body 10 is any value between 5 and 12 mm. In this way, the thick-walled body 10 has a more suitable thickness, avoiding the thick thickness of the thick-walled body 10 causing more refraction loss to the light, and also avoiding the thin thickness of the thick-walled body 10 causing its structural strength to be thin, so that the thick-walled body 10 has better structural stability. For example, the thickness of the thick-walled body 10 can be 5 mm, 8 mm, 10 mm or 12 mm, etc., and can be set according to actual needs. The embodiment of the present application does not limit the specific thickness of the thick-walled body 10.
[0050] In the embodiment of the present application, optionally, the spacing between the light incident surface 11 and the light emitting surface 12 is any value in the range of 40-70 mm. The spacing between the light incident surface 11 and the light emitting surface 12 is also the depth of the thick-walled body 10. The spacing between the light incident surface 11 and the light emitting surface 12 is set to any value in the range of 40-70 mm, so that the thick-walled body 10 has a more suitable depth, avoiding the thick-walled body 10 having a greater depth and causing more refraction loss to the light, and also avoiding the thick-walled body 10 having a smaller depth and being difficult to meet the installation requirements of the thick-walled body 10.
[0051] In summary, the thick-walled light guide structure described in the embodiments of the present application may at least include the following advantages:
[0052] In the embodiment of the present application, the thick-walled light-guiding structure comprises: a thick-walled body, the thick-walled body comprises an arc-shaped light-entering surface and an arc-shaped light-emitting surface which are arranged opposite to each other; the light-entering surface is provided with a light-guiding surface, the light-guiding surface is arranged obliquely relative to a preset reference surface, and the preset reference surface is perpendicular to the direction of the optical axis of the incident light; the curvature of the light-emitting surface is a gradual curvature, and the inclination angle of the light-guiding surface is positively correlated with the curvature of the light-emitting surface corresponding to the light-guiding surface. In this way, a structure similar to a collimating structure is formed between the light-guiding surface and the light-emitting surface on the light-entering surface. When the incident light enters from the light-entering surface, the refraction of the incident light at a larger angle offset caused by the position of the light-entering surface with a larger curvature can be alleviated through refraction by the light-guiding surface, so that more incident light can be aligned relative to the light-emitting surface, and then emitted from the light-emitting surface, so that the light intensity and brightness transition of the emitted light is relatively smooth, the light-emitting effect of the emitted light is improved, and the light-emitting granular effect produced at the position of the thick-walled body with a larger curvature is reduced. In this way, there is no need to set an optical pattern on the light-emitting surface of the thick-walled light-guiding structure, making its shape relatively simple, and there is no need to strictly anchor the light-guiding surface to the direction of the demolding, which simplifies the difficulty of opening the mold of the thick-walled light-guiding structure, facilitates demolding, and reduces production costs. In the embodiment of the present application, the inclination angle of the light-guiding surface relative to the preset reference surface can be flexibly adjusted according to the curvature change of the light-emitting surface to adapt to a variety of thick-walled bodies of different shapes, and the compatibility of the thick-walled light-guiding structure is also improved.
[0053] The embodiment of the present application also proposes a vehicle lamp structure, which includes a mounting plate, a light-emitting component 20, a reflective component 30 and the thick-walled light-guiding structure; the light-emitting component 20 is connected to the mounting plate, the reflective component 30 is arranged on one side of the light-emitting component 20, and the thick-walled light-guiding structure is arranged on the side of the light-emitting component 20 away from the reflective component 30, the light-emitting component 20 emits light to the reflective component 30, and the reflective component 30 reflects the light to the thick-walled light-guiding structure.
[0054] In this way, a light source is provided by the light-emitting component 20, and a relatively stable and reliable installation is provided for the light-emitting component 20 through the mounting plate. The reflective component 30 first reflects and diffuses the light emitted by the light-emitting component 20, and then emits the light through the thick-walled light-guiding structure. Since the light incident surface 11 of the thick-walled body 10 of the thick-walled light-guiding structure is provided with a microstructure having an inclined light-guiding surface 14, the microstructure on the light-guiding unit 13 forms a structure similar to a collimating structure through the light-guiding surface 14 and the light-emitting surface 12. When the incident light enters from the light incident surface 11, the refraction of the light-guiding surface 14 on the microstructure can alleviate the refraction of the incident light at a large angle deviation caused by the position of the light incident surface 11 with a larger curvature, so that more incident light can be aligned relative to the light-emitting surface 12, and then emitted from the light-emitting surface 12, so that the light intensity brightness transition of the emitted light is relatively smooth, thereby improving the light emission effect of the emitted light and reducing the light emission granularity effect produced at the position with a larger curvature on the thick-walled body 10.
[0055] Optionally, in the embodiment of the present application, the light-emitting element 20 includes a plurality of lamp bodies, which are connected to the mounting plate at intervals, and the reflector 30 includes a plurality of mutually connected reflective bowls 31, and the lamp body emits the light to the reflective bowl 31; one reflective bowl 31 is covered on one of the lamp bodies, and the light-guiding surface 14 of the light-guiding unit 13 of the thick-walled light-guiding structure is arranged opposite to the reflective bowl 31. Specifically, a relatively stable and reliable light source is provided by the lamp body, and a plurality of mutually connected reflective bowls 31 constitute the reflector 30, the lamp body emits the light to the reflective bowl 31 for single-side light emission, one reflective bowl 31 is covered on one of the lamp bodies, and the light emitted by the lamp body is reflected by the reflective bowl 31, and the light-guiding surface 14 of the thick-walled light-guiding structure is arranged opposite to the reflective bowl 31. In this way, the light reflected and diffused by the reflective bowl 31 is propagated to the light-guiding surface 14 of the thick-walled light-guiding structure, so that the light reaching the thick-walled structure has a larger light-emitting range.
[0056] Specifically, in the embodiment of the present application, the lamp body can be arranged along the changing trajectory of the arc structure of the light emitting surface 12 of the thick-walled light guide structure, and the reflective bowl 31 can also be arranged along the changing trajectory of the arc structure of the light emitting surface 12 of the thick-walled light guide structure, and the reflective bowl 31 and the light guiding unit 13 of the thick-walled light guide structure are both facing the straight light emitting direction of the lamp body, so that more light emitted by the lamp body reaches the reflective bowl 31, and the reflective bowl 31 can reflect and diffuse more light to the thick-walled light guide structure.
[0057] In the embodiment of the present application, for example, the diffusion effect of the reflective bowl 31 can be adjusted by adjusting the curvature of the reflective bowl 31. Compared with the solution of setting a concentrator in the prior art, the reflective bowl 31 has better adjustability, and different curvatures can be set for different reflective bowls 31. It can be adjusted according to actual needs and can be applicable to a variety of different vehicles and headlight structures, with good compatibility.
[0058] For example, in the embodiment of the present application, the lamp body can be an LED (Light Emitting Diode) lamp, or an OLED (Organic Light Emitting Diode) lamp, etc., and the embodiment of the present application does not limit the specific type of the lamp body. The reflective bowl 31 is a reflective parabolic reflective structure with a bee eye structure, and two adjacent reflective bowls 31 can be connected through a reflective surface. There are many reflective member 30 structures with reflective bowls 31 in the prior art, and the embodiment of the present application does not limit the specific type of the reflective member 30.
[0059] In the embodiment of the present application, the vehicle lamp structure optionally includes an atomizer 40, which is disposed between the reflector 30 and the thick-walled light guide structure, and diffuses the light reflected from the reflector 30 to the thick-walled light guide structure. In this way, the light emitted by the light emitting element 20 is first reflected and diffused into the atomizer 40 by the light emitting element 20, and then the light is reflected and diffused into the thick-walled light guide structure by the atomizer 40 for a second time, so that the light entering the thick-walled light guide structure is more uniform, and then the uniform light is emitted from the light emitting surface 12 of the thick-walled light guide structure under the action of the waveguide.
[0060] For example, in the embodiment of the present application, the thickness of the atomizer 40 can be 3 mm, 2 mm, or 3.5 mm, etc., which can be set according to actual needs. The embodiment of the present application does not limit the thickness of the atomizer 40. In addition, there are many different atomizer 40 structures in the prior art, and the embodiment of the present application does not limit the specific type of the atomizer 40.
[0061] Optionally, in the embodiment of the present application, the projection of the atomizer 40 along the optical axis of the incident light on the preset reference surface is the first projection, and the projection of the thick-walled light guide structure along the optical axis of the incident light on the preset reference surface is the second projection, the first projection is larger than the second projection, and the first projection covers the second projection, and the preset reference surface is a plane perpendicular to the optical axis of the incident light. In this way, the diffused light homogenized by the atomizer 40 can cover the thick-walled light guide structure, so that more diffused light enters the thick-walled light guide structure, so that the thick-walled light guide structure emits more light, and has a better light output effect.
[0062] In the embodiment of the present application, optionally, the projection of the reflector 30 along the optical axis of the incident light on the preset reference surface is a third projection, the third projection is larger than the second projection, and the third projection covers the second projection. In this way, the light diffused by the reflector 30 can also cover the thick-walled light guide structure, so that more diffused light enters the thick-walled light guide structure, so that the thick-walled light guide structure emits more light, and has a better light emitting effect. Specifically, the reflective bowls 31 of the reflector 30 are distributed in an array, and the projection surface of the reflective bowl 31 in the light emitting direction includes the light-incoming surface of the thick-walled light guide structure, so that the light-incoming surface of the thick-walled light guide structure is completely radiated.
[0063] Optionally, in the embodiment of the present application, the lamp body includes a first lamp body and a second lamp body, the first lamp body is located at the focus of the reflective bowl 31, and the second lamp body is set away from the focus of the reflective bowl 31. In this way, the multifunctional light-emitting element 20 is formed by the first lamp body and the second lamp body. Specifically, the first lamp body is located at the focus of the reflective bowl 31 and can be used as the first functional light-emitting element 20, and the second lamp body is set away from the focus of the reflective bowl 31, that is, the second lamp body is defocused and can be used as the second functional light-emitting element 20, thereby realizing a multifunctional design of the light-emitting element 20.
[0064] For example, in an embodiment of the present application, the light emitting color of the first lamp body may be different from that of the second lamp body, or the light emitting shape of the first lamp body may be different from that of the second lamp body, so that multiple functions of the light-emitting component 20 can be realized through the first lamp body and the second lamp body. The embodiment of the present application does not limit the specific light emitting type of the first lamp body and the second lamp body.
[0065] In the embodiment of the present application, optionally, the reflective bowl 31 diffuses the light emitted by the lamp body, and the diffuse area of the reflective bowl 31 in the horizontal direction is the first area, and the diffuse area of the reflective bowl 31 in the vertical direction is the second area, and the first area is larger than the second area. In this way, the diffuser of the reflective bowl 31 in the horizontal direction is larger than the diffuser of the reflective bowl 31 in the vertical direction, thereby reducing the situation where the waveguide effect of the reflected light in the horizontal direction causes the generation of dark areas, and alleviates the large gradient phenomenon when the light transitions from dark to bright at a large angle. In addition, more light is diffused in the horizontal direction, which can have a gathering effect on the light diffusion in the vertical direction, and can also further improve the light efficiency.
[0066] In summary, the vehicle lamp structure described in the embodiment of the present application can at least include the following advantages:
[0067] In an embodiment of the present application, the vehicle lamp structure includes a mounting plate, a light emitting member, a reflector, and the thick-walled light guide structure; the light emitting member is connected to the mounting plate, the reflector is arranged on one side of the light emitting member, the thick-walled light guide structure is arranged on the side of the light emitting member away from the reflector, the light emitting member emits light to the reflector, and the reflector reflects the light to the thick-walled light guide structure. The thick-walled light guide structure includes: a thick-walled body, the thick-walled body includes an arc-shaped light incident surface and an arc-shaped light exit surface that are arranged oppositely; the light incident surface is provided with a light guiding surface, the light guiding surface is inclined relative to a preset reference surface, and the preset reference surface is perpendicular to the direction of the optical axis of the incident light; the curvature of the light exit surface is a gradual curvature, and the inclination angle of the light guiding surface is positively correlated with the curvature of the light exit surface corresponding to the light guiding surface. In this way, a structure similar to a collimating structure is formed between the light-guiding surface and the light-emitting surface on the light-entering surface. When the incident light enters from the light-entering surface, the refraction of the light-guiding surface, which causes a large angle deviation of the incident light, can be alleviated, so that more incident light can be aligned relative to the light-emitting surface, and then emitted from the light-emitting surface, so that the intensity and brightness transition of the emitted light is relatively smooth, thereby improving the light-emitting effect of the emitted light and reducing the light-emitting granular effect produced at the position with a large curvature on the thick-walled body. In this way, there is no need to set an optical pattern on the light-emitting surface of the thick-walled light-guiding structure, so that its shape is relatively simple, and there is no need to strictly anchor the ejection direction of the light-guiding surface, which simplifies the difficulty of opening the mold of the thick-walled light-guiding structure, facilitates ejection, and reduces production costs. In the embodiment of the present application, the inclination angle of the light-guiding surface relative to the preset reference surface can be flexibly adjusted according to the change of the curvature of the light-emitting surface to adapt to thick-walled bodies of various shapes, thereby improving the compatibility of the thick-walled light-guiding structure.
