[0002] In the current design of car lights, for signal lights with low energy requirements, in order to obtain a uniform lighting effect, the inner light mirror material generally uses scattering materials, or is achieved by adding leather grain on the inner and outer surfaces of the inner light mirror. For signal lights with slightly higher energy requirements, in order to make the shape less monotonous, regular patterns such as fisheyes or horizontal and vertical stripes are generally added to the inner light mirror. Whether it is through the selection of materials to make the lighting effect uniform, or through the pattern to make the inner shape more monotonous, the luminous effect produced on this basis is a two-dimensional plane effect, and the luminous effect appears monotonous and dull.

The internal light distribution mirror can ensure relative lighting uniformity and has the optical effect of diffusing light, so that the lighting effect can present a three-dimensional stereoscopic effect, and the lighting effect is more vivid.

[0006] As an implementable manner, the side edges of the pyramid-like are curves or straight lines.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0034] In addition, the terms "horizontal" and "vertical" do not mean that the components must be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0035] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] Please refer to Figures 1 to 11 An embodiment of the present application provides an internal light distribution mirror, wherein the inner surface and / or outer surface of the refractive portion thereof is provided with a light distribution pattern 100, the light distribution pattern 100 is composed of a plurality of pyramid-like prisms, the bottom surface of the pyramid-like prisms is a curved surface, the bottom surfaces of every two adjacent pyramid-like prisms share an edge, at least two pyramid-like prisms have different bottom surfaces, and the bottom surfaces of the plurality of pyramid-like prisms are located on the same common curved surface.

[0037] Among them, the refractive part of the inner light distribution mirror refers to the partial structure used to receive light and project the light to the outer light distribution mirror through refraction. By providing a light distribution pattern 100 on its inner surface and / or outer surface, the inner light distribution mirror provided by the present application has a three-dimensional luminous effect, which can ensure that the lighting effect is relatively uniform and continuous like a scattering material and is not monotonous in appearance, thereby playing a role in beautifying the lamp.

[0038] Regarding how to set the light distribution pattern 100 on the inner surface and / or outer surface of the refractive part of the inner light distribution mirror, there are three cases: the first case is to set the light distribution pattern 100 on the inner surface, while the outer surface is a smooth surface without patterns; the second case is to set the light distribution pattern 100 on the outer surface, while the inner surface is a smooth surface without patterns; the third case is to set the light distribution pattern 100 on both the inner surface and the outer surface. Those skilled in the art should be able to make reasonable selections and designs according to actual conditions, and no specific restrictions are made here.

[0039] Specifically, the light distribution pattern 100 is composed of a plurality of pyramid-like structures, where the pyramid-like structures refer to structures with curved bottom surfaces. Regarding the specific number of pyramid-like structures included in the light distribution pattern 100, those skilled in the art should be able to reasonably select and design the number according to the area of ​​the inner light distribution mirror and the area of ​​the bottom surface of each pyramid-like structure, and no specific limitation is imposed here, as long as the bottom surfaces of every two adjacent pyramid-like structures share one edge, the bottom surfaces of at least two pyramid-like structures are not completely the same, and the bottom surfaces of the plurality of pyramid-like structures are located on the same common curved surface (i.e., the inner surface or outer surface of the inner light distribution mirror).

[0040] When designing the light distribution pattern 100, the bottom surface shape, area size, and number of bottom edges 10 of each pyramid-like prism constituting the light distribution pattern 100 are all random. For example, multiple design elements of the bottom surfaces of two pyramid-like prisms constituting the light distribution pattern 100 can be the same. As long as one design element is different, the bottom surfaces of the two pyramid-like prisms can be different.

[0041] Therefore, when light is irradiated onto the inner light distribution mirror, the refraction of the light distribution pattern 100 provided on the inner surface and / or outer surface of the refractive portion thereof not only ensures the relative lighting uniformity, but also effectively diffuses the light. At the same time, since the multiple pyramid-like prisms constituting the above-mentioned light distribution pattern 100 are random, different light and shadow effects can be achieved, thereby presenting a three-dimensional luminous feature.

[0042] The following is a more detailed explanation of the pyramid-like structure with reference to the relevant concepts of the pyramid structure. First, the plane where the vertices A of the bottom surface are located is defined as the XY plane, and the direction perpendicular to the XY plane is defined as the Z axis, thereby constructing a three-dimensional rectangular coordinate system, in which the vertex S of the pyramid-like structure is located in the XY plane, the positive direction of the Z axis, or the negative direction of the Z axis.

[0043] In other words, the positional relationship between the pyramid-like vertex S and the vertices A of the bottom surface is random. The two may be located on the same common plane (i.e., the XY plane), or the pyramid-like vertex S may protrude from the plane where the vertices A of the bottom surface are located (i.e., the XY plane), or the pyramid-like vertex S may be recessed in the plane where the vertices A of the bottom surface are located (i.e., the XY plane). As a result, the side surfaces of the pyramid-like refract the light at different angles to form diffusion.

[0044] For example, Figures 1 to 3 As shown, in some embodiments, the vertex S of the pyramid-like prism is located on the XY plane, that is, the vertex S of the pyramid-like prism and the vertices A of the bottom surface are located on the same common plane; Figures 4 to 6 , Fig.10 and Fig.11 As shown, in other embodiments, the vertex S of the pyramid-like prism is located in the positive direction of the Z axis, that is, the vertex S of the pyramid-like prism protrudes from the plane where the vertices A of the bottom surface are located; Figures 7 to 9 As shown, in some other embodiments, the vertex S of the pyramid-like shape is located in the negative direction of the Z axis, that is, at this time, the vertex S of the pyramid-like shape is recessed in the plane where the vertices A of the bottom surface are located.

[0045] When designing the light distribution pattern 100, the shape of the pyramid-like side edge 20 is also random. As an prism-like embodiment, the pyramid-like side edge 20 is a curve or a straight line. For example, Figures 1 to 9 As shown, in some embodiments, the side edge 20 of the pyramid-like shape is a curve; Fig.10 and Fig.11 As shown, in other embodiments, the side edges 20 of the pyramid-like shape are straight lines.

[0046] Optionally, when the side edge 20 of the pyramid-like prism is a curve, the top of the side edge 20 protrudes from the vertex S of the pyramid-like prism. Figures 7 to 9 As shown, in some embodiments, the arch of the side edge 20 protrudes from the pyramid-like vertex S. Of course, in other embodiments, the arch of the side edge 20 can also be between the pyramid-like vertex S and each vertex A of the bottom surface.

[0047] When designing the light distribution pattern 100, the side morphology of the pyramid-like surface is also random. As an prism-like embodiment, the side of the pyramid-like surface is a curved surface or a flat surface. For example, Figures 1 to 9 As shown, in some embodiments, the side surface of the pyramid-like is a curved surface; Fig.10 and Fig.11 As shown, in other embodiments, the side surfaces of the pyramid-like bodies are planes.

[0048] When designing the light distribution pattern 100, the number of the bases 10 of the pyramid-like prisms is random. As an practicable manner, the number of the bases 10 of the pyramid-like prisms is greater than or equal to 3. For example, Figures 1 to 9 As shown, in some embodiments, the number of base edges 10 of the pyramid-like shape is 6; Figure 10 to Figure 11 As shown, in other embodiments, the number of the base edges 10 of the pyramid-like prism is 3. It should be noted that the number of the base edges 10 of the pyramid-like prism should not be too large to avoid the pyramid-like structure being too complicated and causing too high a processing difficulty.

[0049] In addition, the distance between the apex S of the quasi-pyramid and the corresponding bottom surface is defined as the height of the quasi-pyramid. When designing the light distribution pattern 100, the height of the quasi-pyramid is also random. As an implementable method, the distances between the apex S of multiple quasi-pyramids and the corresponding bottom surfaces are equal, which is conducive to simplifying the design of the light distribution pattern 100 and making it easier to control the determination of the design parameters of the light distribution pattern 100.

[0050] As an implementable manner, the interior light mirror is made of a transparent material to refract light. For example, the interior light mirror can be made of PC (polycarbonate) material or PMMA (polymethyl methacrylate) material.

[0051] As an practicable manner, the interior light distribution mirror is integrally injection molded, wherein the light distribution pattern 100 is a part of the interior light distribution mirror and is integrally injection molded with the interior light distribution mirror.

[0052] The embodiment of the present application also provides a vehicle light optical system, including the above-mentioned inner light distribution mirror. Since the structure and beneficial effects of the inner light distribution mirror have been described in detail in the above-mentioned embodiment, they will not be repeated here.

[0053] The embodiment of the present application also provides a vehicle lamp assembly, including the above vehicle lamp optical system. Since the structure and beneficial effects of the vehicle lamp optical system have been described in detail in the above embodiments, they will not be repeated here.

[0054] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0055] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not further describe various possible combinations.
