Description
Technical Field
[0001] The utility model relates to the technical field of automobile lamps, in particular to a novel optical pattern structure. Background Art
[0002] With the rapid development of the automotive industry, the shape of car lights tends to be diversified, pursuing uniqueness, aesthetics and uniform lighting effects. The existing car light patterns are relatively simple, mostly corn kernels, which are prone to aesthetic fatigue among consumers. In conventional thick-walled parts, the exterior surface is usually evenly arranged with quadrilateral corn kernel patterns. Although the corn kernel pattern can improve the uniformity of the lighting appearance of the lamp on the one hand, it can also shield the internal components, prevent the internal installation structure from being directly seen from the outside of the lamp, and enhance the aesthetics of the lamp. However, as the inclination angle of the current car light shape becomes larger and larger, on the base surface with a large inclination, the area of the traditional corn kernel side wall will be much larger than the corn kernel light-emitting surface itself, causing the side wall to easily form bright spots when the lamp turns left or right at a large angle. When the area of the corn kernel side wall becomes larger, other structures inside the lamp can be clearly observed through the side wall, thereby affecting the aesthetics of the static appearance of the lamp. At the same time, the mainstream thick-walled parts on the market currently have relatively monotonous patterns and appearance, lack brand characteristics, lack recognition, and cannot meet the brand tone and uniqueness needs of vehicle manufacturers. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a new optical pattern structure, which can reduce the side wall area of the pattern as much as possible when the inclination of the pattern base surface is large, effectively avoid the large area of bright spots that appear when the lamp is observed at a left or right angle, and at the same time improve the shielding performance of other internal structures.
[0004] In order to solve the above technical problems, the technical solution of the utility model is:
[0005] A novel optical pattern structure, comprising a plurality of rectangular protrusions formed on a base surface of a thick-walled member, wherein the plurality of rectangular protrusions are arranged in a staggered distribution, and each rectangular protrusion has an arched light-emitting surface on its light-emitting side;
[0006] Each rectangular protrusion except the edge is surrounded by at least five rectangular protrusions, and the width of the long side of the arched light-emitting surface is twice the width of the short side.
[0007] Furthermore, the arched light emitting surface has diffusion angles in two directions, and the diffusion range can reach -30° to 30°.
[0008] Furthermore, the arch height of the arched light-emitting surface is 0.01-1 mm.
[0009] Furthermore, the width of the long side of the arched light emitting surface is 1-4 mm, and the width of the short side of the arched light emitting surface is 0.5-2 mm.
[0010] Furthermore, the surface of the arched light-emitting surface is additionally provided with leather grain.
[0011] Furthermore, the arched light-emitting surface has a polishing layer.
[0012] By adopting the above technical solution, the utility model has the following beneficial effects:
[0013] 1. The utility model adopts a staggered arrangement of specific patterns so that when the inclination of the pattern base is large, the side wall area of each rectangular raised pattern will be partially blocked by the adjacent rectangular raised pattern, and the side wall area of the pattern is reduced as much as possible, thereby effectively avoiding the large area of bright spots when observing the lamp at left and right angles, and at the same time, it can also improve the shielding performance of other internal structures and improve the aesthetics of the static appearance of the lamp.
[0014] 2. The utility model solves the problem of single surface pattern of thick-walled parts, enriches the shape of lamps, and can effectively improve the lighting uniformity of lamps, shield the internal structure of lamps, improve the aesthetics, and enhance the brand characteristics and uniqueness of lamps.

[0024] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.
[0025] like Figure 8 As shown, it is a three-dimensional structural effect diagram of conventional corn kernels on a base surface with a large inclination in the prior art. On the base surface with a large inclination, the area of the traditional corn kernel side wall will be much larger than the light-emitting surface of the corn kernel itself, resulting in the side wall being prone to form bright spots when the lamp turns left or right at a large angle. Moreover, when the area of the corn kernel side wall becomes larger, other structures inside the lamp can be clearly observed through the side wall, thereby affecting the aesthetics of the static appearance of the lamp.
[0026] Therefore, if Figure 1-7 As shown, in all embodiments of the utility model, a new optical pattern structure is provided, which is designed to form a plurality of rectangular protrusions 1 on the base surface of a thick-walled part, and the plurality of rectangular protrusions 1 are arranged in a staggered distribution, and each rectangular protrusion 1 has an arched light-emitting surface 10 on the light-emitting side. It is worth mentioning that each rectangular protrusion 1 except the edge has at least five rectangular protrusions 1 around it, and the long side width of the arched light-emitting surface 10 is twice the short side width, which can maximize the overlapping coverage of the side wall surface of adjacent rectangular protrusions 1. In this way, through the staggered arrangement of specific patterns, when the inclination of the pattern base surface is large, the side wall area of each rectangular protrusion 1 pattern will be partially blocked by the adjacent rectangular protrusion 1 pattern, and the side wall area of the pattern is reduced as much as possible, thereby effectively avoiding the large area of bright spots when observing the lamp at a left or right turning angle, and at the same time, it can also improve the shielding performance of other internal structures and improve the aesthetics of the static appearance of the lamp.
[0027] In order to improve the uniformity of lighting, the arched light-emitting surface 10 has a diffusion angle in two directions, and the diffusion range can reach -30°~30°. At the same time, the arch height of the arched light-emitting surface 10 is 0.01-1mm. In order to ensure the staggered and tight arrangement of multiple rectangular protrusions 1 and to increase the shielding area of the side walls of adjacent rectangular protrusions 1 as much as possible, the long side width of the arched light-emitting surface 10 is twice the short side width, the long side width of the arched light-emitting surface 10 is 1-4mm, and the short side width of the arched light-emitting surface 10 is 0.5-2mm.
[0028] According to the requirements of the shape, the surface of the arched light-emitting surface 10 can be provided with leather grain to improve the lighting uniformity. The surface of the arched light-emitting surface 10 can also be polished to meet the shape requirements.
[0029] refer to Figure 1-3 In the embodiment 1 shown, Figure 1is a schematic diagram of a pattern plane of Embodiment 1, Figure 2 This is a three-dimensional structure effect diagram of the pattern of Example 1 on a large-inclined base surface. It can be seen that multiple rectangular protrusions 1 are arranged in a staggered woven distribution, and two types of rectangular protrusions 1 are vertically close to each other. Each rectangular protrusion 1 has an arched light-emitting surface 10 on the light-emitting side. Among them, each rectangular protrusion 1 except the edge is surrounded by six rectangular protrusions 1, and the long side width of the arched light-emitting surface 10 is twice the short side width. The long side width of the arched light-emitting surface 10 is 4mm, and the short side width of the arched light-emitting surface 10 is 2mm. Reference Figure 3 From the enlarged view of the local structure, it can be seen that the side wall A area of each rectangular protrusion 1 pattern in the figure will be partially blocked by the adjacent rectangular protrusion 1 pattern, which can reduce the side wall A area of the pattern as much as possible, thereby effectively avoiding the large area of bright spots when observing the lamp at left and right angles, and at the same time, it can also improve the shielding performance of other internal structures and improve the aesthetics of the static appearance of the lamp.
[0030] refer to Figure 4 , 5 In the second embodiment shown, Figure 4 is a schematic diagram of the pattern plane of the second embodiment, Figure 5 This is a three-dimensional structure effect diagram of the pattern of Example 2 on a large-inclined base surface. It can be seen that multiple rectangular protrusions 1 are arranged in a staggered vertical distribution. Each column of rectangular protrusions 1 is staggered with the two columns of rectangular protrusions 1 on the left and right, so as to achieve the beautiful effect of the pattern flashing alternately when lit. Each rectangular protrusion 1 has an arched light-emitting surface 10 on the light-emitting side. The long side width of the arched light-emitting surface 10 is 2mm, and the short side width of the arched light-emitting surface 10 is 1mm. In addition, it can be seen that each rectangular protrusion 1 is surrounded by six rectangular protrusions 1 except for the edge. Reference Figure 5 As shown, it can be seen that the side wall B area of each rectangular protrusion 1 pattern in the figure will be partially blocked by the adjacent rectangular protrusion 1 pattern, which can reduce the side wall B area of the pattern as much as possible, thereby effectively avoiding the large area of bright spots when observing the lamp at left and right angles, and at the same time can also improve the shielding performance of other internal structures, and improve the aesthetics of the static appearance of the lamp.
[0031] refer to Figure 6 , 7 In the third embodiment shown, Figure 6 is a schematic diagram of the pattern plane of the third embodiment, Figure 7 This is a three-dimensional structure effect diagram of the pattern of Example 3 on a large-inclined base surface. It can be seen that multiple rectangular protrusions 1 are arranged in a staggered horizontal and vertical distribution. One vertical rectangular protrusion 1 is arranged close to two horizontal rectangular protrusions 1. Each rectangular protrusion 1 has an arched light-emitting surface 10 on the light-emitting side. The long side width of the arched light-emitting surface 10 is 1mm, and the short side width of the arched light-emitting surface 10 is 0.5mm. Figure 6It can be seen that there are six rectangular protrusions 1 around the vertical rectangular protrusion 1 except the edge, and there are five rectangular protrusions 1 around the horizontal rectangular protrusion 1. Figure 7 As shown, relying on the compact staggered arrangement, it can be seen that the side wall area of each rectangular protrusion 1 pattern in the figure will be partially blocked by the adjacent rectangular protrusion 1 pattern, which can reduce the side wall area of the pattern as much as possible, thereby effectively avoiding the large area of bright spots when observing the lamp at left and right angles, and at the same time, it can also improve the shielding performance of other internal structures and improve the aesthetics of the static appearance of the lamp.
[0032] Through the above scheme of this embodiment, it can be seen that when the base surface of the pattern is relatively inclined, the area of the side wall of the rectangular protrusion 1 is blocked by the mutually staggered rectangular protrusions 1, so that the area of the side wall is reduced, thereby effectively avoiding the large area of bright spots when observing the lamp at left and right angles. The thick-walled part where the pattern is located can be combined with currently commonly used optical solutions such as concentrators and reflectors, and can also be used in combination with another thin-walled part, thick-walled part, scattering material, etc. in actual design. The LED light color is not limited. As long as it is reasonably combined with electronic design, the pattern of this embodiment can be flexibly applied to a variety of lamp functions.
[0033] In addition, it can be seen from the solutions of the above embodiments that the utility model solves the problem of single surface pattern of thick-walled parts, enriches the shape of lamps, and at the same time can effectively improve the lighting uniformity of lamps, shield the internal structure of lamps, improve the aesthetics, and enhance the brand characteristics and uniqueness of lamps.
