[0034] The specific implementation mode of the utility model is described in detail below in conjunction with the drawings, and it should be understood that the specific implementation mode described herein is only used to illustrate and explain the utility model, and the protection scope of the utility model is not limited to the following specific implementation mode.
[0035] In the description of the utility model, it should be pointed out that, unless otherwise explicitly specified and limited, the terms "set", "provided with", "connected" should be understood broadly, for example, the connection can be direct connection or indirect connection through intermediate connecting piece, can be the internal communication of two elements or the interaction relationship of two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0036] It needs to be understood that, for the convenience of describing the utility model and simplifying the description, the terms "front, rear" refer to the front-rear direction of the light collector along the light emitting direction, which is generally the same as the front-rear direction of the vehicle, for example, the light emitting surface of the light collector is located in the front, and correspondingly, the light entering end of the light collector is located in the rear, the terms "left, right" refer to the left-right direction of the light collector itself, which is generally the same as the left-right direction of the vehicle in the use process, and the terms "up, down" refer to the up-down direction of the light collector itself; the terms are based on the orientation or positional relationship shown in the drawings, and are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the utility model; moreover, when the light collector is installed in the vehicle, it can be installed in various orientations such as the horizontal direction and the vertical direction, and the orientation terms of the light collector of the utility model should be understood in combination with the actual installation state.
[0037] In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features, therefore, the features limited by "first", "second" can explicitly or implicitly include one or more of the features.
[0038] Referring to Figures 1 to 12 The utility model provides a light collector, with light collector light emitting surface, light collector light emitting surface includes first light emitting surface 1 and at least one second light emitting surface 2 set up in the both sides of first light emitting surface 1, and the second light emitting surface 2 is provided with pattern structure 3.
[0039] Wherein, first light emitting surface 1 is located in the middle of light collector light emitting surface, its role is to provide the illumination intensity for the illumination light type formed by light collector, and ensure the center brightness value of the illumination light type formed by light collector, and the second light emitting surface 2 provided with pattern structure 3 set up in the both sides of first light emitting surface 1 can diffuse light, so that the illumination light type formed by second light emitting surface 2 has enough spread, that is, the illumination range of the illumination light type meets the requirements, and in the case of setting multiple second light emitting surfaces 2, the connection or superposition of the sub-illumination light type formed by each second light emitting surface 2 can be ensured more evenly.
[0040] It needs to be explained that the number of second light emitting surface 2 can be set according to the actual use. The light collector provided by the utility model can effectively ensure the illumination range of the illumination light type while meeting the illumination intensity requirements, and improve the quality of vehicle lamp and reduce the use cost.
[0041] Specifically, as Figures 1 to 4As shown, as a preferred embodiment provided by the utility model, the light collector can be a high beam light collector, the light collector light exit surface of the high beam light collector includes first light exit surface 1 and second light exit surface 2, and the first light exit surface 1 is located in the middle of the light collector light exit surface, and the second light exit surface 2 is arranged on both sides of the first light exit surface 1, for example, the second light exit surface 2 can be symmetrically arranged about the first light exit surface 1, such as Figure 1 As shown, the first light exit surface 1 is not provided with the pattern structure 3, the second light exit surface 2 on both sides of the first light exit surface 1 can be two respectively, the pattern structure 3 is arranged on the second light exit surface 2, when the light is emitted from the light collector light exit surface, because the pattern structure 3 is arranged on the second light exit surface 2, the light is diffused through the pattern structure 3, so that the high beam sub-illumination light type formed by each second light exit surface 2 has sufficient illumination range and the connection or superposition of each high beam sub-illumination light type is more uniform; at the same time, because the first light exit surface 1 is not provided with the pattern structure 3, the light is basically not diffused when passing through the first light exit surface 1, the high beam sub-illumination light type formed by the first light exit surface 1 has sufficient illumination intensity, and because the first light exit surface 1 is arranged in the middle of the light collector light exit surface, the center brightness value of the high beam illumination light type is ensured, the regulation requirements are met, and additional LED and other light sources are not needed to increase the illumination intensity of the high beam illumination light type, the quality of the vehicle lamp is improved, and the use cost is reduced.
[0042] Further, as some specific embodiments of the utility model, an included angle is formed between the transverse section of the first light exit surface 1 and the transverse section of the second light exit surface 2, and an included angle is formed between the transverse sections of two adjacent second light exit surfaces 2.
[0043] It should be noted that the transverse direction refers to the left-right direction of the light collector itself, which is generally the same as the left-right direction of the vehicle in use, and the longitudinal direction refers to the up-down direction of the light collector itself, which is also generally the same as the up-down direction of the vehicle in use.
[0044] It can be understood that, as Figure 3 and Figure 4As shown, the transverse cross-section of the first light-emitting surface 1 and the transverse cross-section of the second light-emitting surface 2 form an angle, causing the first light-emitting surface 1 and the second light-emitting surfaces 2 on both sides of the first light-emitting surface 1 to form a forward-convex shape. This makes the first light-emitting surface 1 closer to the lens than the second light-emitting surface 2, preventing light rays passing through the first light-emitting surface 1 from re-entering the second light-emitting surface 2 and causing light crosstalk. This ensures the amount of light rays converged through the first light-emitting surface 1, guarantees the center brightness value of the illumination pattern formed by the condenser, and ensures that the illumination pattern has sufficient light intensity. At the same time, the second light-emitting surfaces 2, which are arranged on both sides of the first light-emitting surface 1, can be connected sequentially in the transverse direction. An angle is formed between the transverse sections of two adjacent second light-emitting surfaces 2. The farther away from the first light-emitting surface 1, the larger this angle. Therefore, the further away the second light-emitting surface 2 is from the first light-emitting surface 1, the smaller the slope change of the second light-emitting surface 2. This makes the light-emitting surface of the concentrator generally form a forward-convex shape, thereby ensuring that light passing through the first light-emitting surface 1 does not enter the second light-emitting surface 2, thus ensuring the brightness value of the illumination pattern formed by the concentrator. Simultaneously, as... Figures 7 to 12 As shown, since the slope of the second light-emitting surface 2 becomes smaller and smaller along the direction away from the first light-emitting surface, when the light passes through the second light-emitting surface 2, it can further ensure the uniform connection or superposition of the sub-illumination light patterns formed by each second light-emitting surface 2.
[0045] In addition, the size of the overlapping area between two adjacent sub-illumination patterns can be adjusted by adjusting the angle between the transverse section of the first light-emitting surface 1 and the transverse section of the second light-emitting surface 2 and / or the angle between the transverse sections of two adjacent second light-emitting surfaces 2, so as to ensure the uniformity of the illumination pattern and the lighting effect.
[0046] Furthermore, as some specific embodiments of this utility model, the pattern structure 3 includes at least one set of striped patterns 31, each striped pattern 31 extending longitudinally along the light-emitting surface of the concentrator and distributed laterally along the light-emitting surface of the concentrator. The striped patterns 31, while diffusing light, can ensure uniform connection or superposition of the sub-illumination patterns formed by each of the second light-emitting surfaces 2. It is understood that, as... Figures 1 to 4 As shown in the figure, in a specific embodiment of the present invention, a pattern structure 3 is provided on the second light-emitting surface 2, and the pattern structure 3 includes at least one set of strip patterns 31. The transverse cross-sectional outline of the strip pattern 31 can be a concave rectangular outline. The strip pattern 31 extends longitudinally along the light-emitting surface of the concentrator. At the same time, several strip patterns 31 are distributed transversely along the light-emitting surface of the concentrator. Therefore, when the light passes through the strip pattern 31, it can be deflected to the outside of the vehicle, so that the light diffusion angle increases and the width of the sub-illumination pattern formed by the second light-emitting surface 2 is increased, ensuring the illumination range of the illumination pattern. At the same time, through several strip patterns 31, the connection or superposition of the sub-illumination patterns formed by each second light-emitting surface 2 can be made uniform.
[0047] Further, the width of the strip pattern 31 gradually increases along the direction away from the first light emitting surface 1. By setting the width of the strip pattern 31 gradually increasing, the outer side of the sub-illumination light pattern formed by each second light emitting surface 2 is widened, so that the illumination range of the sub-illumination light pattern is increased, while ensuring that the connection or superposition of the sub-illumination light pattern formed by each second light emitting surface 2 is uniform. It should be noted that the feature that the width of the strip pattern 31 gradually increases along the direction away from the first light emitting surface 1 includes two cases. First, within any second light emitting surface 2, the width of the strip pattern 31 gradually increases along the direction away from the first light emitting surface 1; second, the width of the strip pattern 31 on all adjacent second light emitting surfaces 2 also satisfies the variation rule, for example, there are two adjacent second light emitting surfaces 2, the width of the strip pattern 31 on the second light emitting surface 2 close to the first light emitting surface 1 is smaller, the width of the strip pattern 31 on the second light emitting surface 2 away from the first light emitting surface 1 is larger, and the width still increases gradually at the junction of the two second light emitting surfaces 2.
[0048] Specifically, as some specific embodiments of the present application, the width of the strip pattern 31 ranges from 0.79mm to 1.16mm.
[0049] It can be understood that, as shown in Figures 1 to 4 , the maximum width of the strip pattern 31 is 1.16mm, and the minimum width is 0.79mm. The width of the strip pattern 31 gradually increases along the direction away from the first light emitting surface 1, and the width can increase from 0.79mm to 1.16mm, or from 0.8mm to 1.15mm. The range of the increase is not limited here. The increase in the width of the strip pattern 31 makes the light more diffuse, which can increase the outer side of the illumination light pattern, ensure the illumination range of the illumination light pattern, and at the same time, through the arrangement of a plurality of strip patterns 31, the connection or superposition of the sub-illumination light pattern corresponding to adjacent second light emitting surfaces 2 is uniform.
[0050] It should be noted that, for the specific structure of the strip pattern 31, the above-mentioned transverse cross-sectional profile of the strip pattern 31 is rectangular, which is only one of the embodiments. In addition, the transverse cross-sectional profile of the strip pattern 31 can also be arc-shaped, triangular, etc. Specifically, it can be set according to the actual needs of use.
[0051] Further, as some specific embodiments of the present application, the first light emitting surface 1 is a planar light emitting surface, as shown in Figures 1 to 4 , the first light emitting surface 1 can be arranged in the middle of the light emitting surface of the condenser, so that the light is directly emitted from the planar light emitting surface without diffusion, providing illumination intensity for the illumination light pattern formed by the condenser, ensuring the brightness value of the central light pattern formed by the condenser, meeting the illumination intensity requirement of the illumination light pattern, without the need to increase the light source, reducing the use cost.
[0052] It should be noted that the specific structure of the first light exit surface 1, the flat light exit surface is only one specific embodiment of the first light exit surface 1, the first light exit surface 1 can also be an arc-shaped light exit surface, and is convexly arranged in the direction away from the light entrance end of the light collector, the arc-shaped light exit surface has a converging effect on the light, and ensures the brightness value of the illumination light pattern formed by the light collector.
[0053] Further, as some specific embodiments of the present application, as shown in Figure 4 The first light exit surface 1 and the second light exit surface 2 and the pattern structure 3 are integrally formed, which ensures the structural stability of the light exit surface of the light collector and can reduce the production cost.
[0054] Referring to Figure 5 As some specific embodiments of the present application, the light entrance end of the light collector is a light collector cup 5, the light collector cup 5 is correspondingly provided with a light source 4, and the first light exit surface 1 and the second light exit surface 2 are respectively correspondingly provided with at least one light collector cup 5.
[0055] As can be understood, as shown in Figures 4 to 6 The light source 4 is arranged at the light entrance end of the light collector, the light entrance end of the light collector is a light collector cup 5, and the light source 4 is correspondingly arranged with the light collector cup 5. As shown in Figure 5 The light collector cup 5 can be correspondingly arranged with the light source 4, or can be correspondingly arranged with multiple light sources 4, which is not limited here. In addition, the first light exit surface 1 and the second light exit surface 2 can be correspondingly arranged with one light collector cup 5, or can be correspondingly arranged with multiple light collector cups 5, which is not limited here. When the number of light sources 4 increases or the number of light collector cups 5 increases, the brightness value of the illumination light pattern formed by the light collector can be increased.
[0056] In addition, the second aspect of the present application also provides an optical module, which has the light collector of the above-mentioned scheme. The illumination light pattern formed by the light collector in the optical module can effectively ensure the illumination range while meeting the requirement of illumination intensity, improve the quality of the vehicle lamp while reducing the use cost.
[0057] Further, the third aspect of the present application also provides a vehicle lamp, which comprises the optical module of the above-mentioned technical scheme. The illumination effect of the vehicle lamp is improved, and the use cost is reduced.
[0058] In order to better understand the technical scheme of the present application, the preferred embodiments are described below in combination with the relatively comprehensive preferred technical features:
[0059] As shown in Figures 1 to 12As shown, the application provides a light collector, which has a light collector light exit surface, the light collector light exit surface comprises a first light exit surface 1 and four second light exit surfaces 2, wherein the first light exit surface 1 is arranged in the middle of the light collector light exit surface, two second light exit surfaces 2 are sequentially arranged on both sides of the first light exit surface 1 along the transverse direction of the light collector, and a pattern structure 3 is formed on the second light exit surface 2. An included angle is formed between the transverse section of the first light exit surface 1 and the transverse section of the second light exit surface 2, the first light exit surface 1 and the second light exit surface 2 form a forward convex shape, and an included angle is formed between the transverse sections of the two adjacent second light exit surfaces 2, the farther away from the first light exit surface 1, the larger the included angle, so the farther away from the first light exit surface 1, the smaller the slope change of the second light exit surface 2, and the size of the overlapping area between the sub-illumination light patterns formed by the second light exit surfaces 2 can be changed by changing the size of the included angle, so that the connection or superposition between the two adjacent sub-illumination light patterns is uniform.
[0060] Further, the pattern structure 3 comprises a plurality of strip patterns 31, each strip pattern 31 extends along the longitudinal direction of the light collector light exit surface and is distributed along the transverse direction of the light collector light exit surface, wherein the width of the strip pattern 31 arranged on each second light exit surface 2 gradually increases in the direction away from the first light exit surface 1, or the width of each strip pattern 31 on the two adjacent second light exit surfaces 2 still gradually increases in the direction away from the first light exit surface 1, and specifically, the width can increase from 0.79 mm to 1.16 mm. The strip pattern 31 on the second light exit surface 2 can make the lateral width of the sub-illumination light pattern formed by each second light exit surface 2 larger, and ensure the illumination range of the illumination light pattern, and the first light exit surface 1 is preferably a planar light exit surface, which ensures that the light passes through the first light exit surface without diffusion, and ensures the brightness value of the central light pattern, and specifically, the first light exit surface 1, the second light exit surface 2 and the pattern structure 3 are integrally formed, which ensures the structural stability of the light collector light exit surface, and also saves the production cost of the light collector.
[0061] wherein, Figure 11 The sub-illumination light pattern formed by the first light exit surface 1 has a high brightness value. Figure 8 and Figure 10 are respectively the sub-illumination light patterns formed by the second light exit surfaces 2 located close to the first light exit surface 1 and respectively located on the right side and the left side of the first light exit surface 1; Figure 7 and Figure 9 are respectively the sub-illumination light patterns formed by the second light exit surfaces 2 located away from the first light exit surface 1 and respectively located on the right side and the left side of the first light exit surface 1, and Figures 7 to 9 It can be seen that as the width of the strip pattern 31 gradually increases in the direction away from the first light exit surface 1, the lateral width of the corresponding formed sub-illumination light pattern will also become larger, and the illumination range will increase accordingly. As Figure 12As shown, as a specific embodiment of the utility model, the light type is the final illumination light type formed by the combination of the corresponding sub-illumination light type of the first light exit surface 1 and the second light exit surface 2, the illumination light type has high light intensity, large illumination range and uniform illumination light type.
[0062] The pattern structure 3 provided on the second light exit surface 2 can increase the diffusion of light, increase the lateral expansion of the corresponding sub-illumination light type, and further expand the illumination range of the sub-illumination light type formed by each second light exit surface 2, while the first light exit surface 1 ensures the brightness value of the illumination light type formed by the light collector, meets the illumination intensity requirement of the illumination light type, and does not need to increase the light source, thereby reducing the use cost.
