[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0038] The circuit board unit, printed circuit board, optical module, vehicle lamp and vehicle in this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] In the existing technology, multiple LEDs are set on the printed circuit board of the lamp to meet diverse usage needs, and different functions are achieved by controlling the LEDs to turn on and off; however, if the LED positions are not arranged reasonably, the illuminated area will shift when switching between different functions, resulting in poor visual effects.

[0040] To address the aforementioned technical problems, this application provides a circuit board unit, including a board body and an LED bead assembly. The board body has a dimension larger in a first direction than its dimension in a second direction, the first direction being perpendicular to the second direction, and both the first and second directions being parallel to the board surface. An LED bead assembly is disposed on the board surface, with multiple sets of LED bead assemblies spaced apart along the first direction, and one set of LED bead assemblies located along the second direction. Each LED bead assembly includes multiple LEDs spaced apart along the second direction. A projection plane λ perpendicular to the second direction is defined, and within the same LED bead assembly, the orthographic projections of adjacent LEDs on the projection plane λ at least partially overlap. This will be described in detail below.

[0041] See Figure 1 and Figure 2The circuit board unit 11 includes a board body 111 and an LED bead group 112. The size of the board body 111 in a first direction is larger than its size in a second direction. The first direction is perpendicular to the second direction, and the first direction and the second direction are parallel to the board surface of the board body 111. The LED bead group 112 is disposed on the board surface of the board body 111. Multiple groups of LED bead groups 112 are spaced apart along the first direction, and one group of LED bead groups 112 is disposed in the second direction. The LED bead group 112 includes multiple LED beads 1121 spaced apart along the second direction. A projection surface λ is set perpendicular to the second direction. In the same LED bead group 112, the orthographic projections of adjacent LED beads 1121 on the projection surface λ at least partially overlap.

[0042] Plate 111 in the first direction (e.g.) Figure 1 The dimension in the middle direction (as shown in X, the same below) is larger than its dimension in the second direction (as shown in X). Figure 1 The dimensions in the Y direction (hereinafter the same) indicate that the board body 111 is elongated, and the circuit board unit 11 is elongated. In actual use, different lengths (dimensions in the first direction, hereinafter the same) and widths (dimensions in the second direction, hereinafter the same) of the circuit board unit 11 can be selected according to the lighting requirements to avoid the circuit board unit 11 occupying the internal space of the headlight. Alternatively, multiple boards 111 can be spliced ​​together to form printed circuit boards 10 of different shapes (including multiple circuit board units 11) according to the headlight shape to meet the personalized lighting requirements of the headlight, reducing the production difficulty of the printed circuit board 10. The complex printed circuit board 10 can be divided into multiple elongated and regular circuit board units 11, thereby reducing production costs. Moreover, the complex printed circuit board 10 (a whole board) is easily damaged by external forces. The splicing of circuit board units 11 can effectively avoid this situation. In addition, installing the circuit board unit 11 separately reduces the assembly difficulty and improves production efficiency compared to installing the whole printed circuit board 10.

[0043] It is worth mentioning that only one set of LED beads 112 is provided in the second direction, which is beneficial to the routing of the circuit board unit 11. The routing of the circuit board unit 11 is mainly arranged along the first direction, making the circuit design simpler and more orderly, reducing line crossings and interference, and improving the reliability and production efficiency of the circuit board unit 11. At the same time, the linear arrangement of LED beads 1121 is conducive to the uniform distribution of heat and avoids excessive heat concentration at a certain point.

[0044] In addition, each group of LED beads 112 is provided with multiple LED beads 1121 spaced apart along the second direction, that is, multiple groups of LED bead arrays 20 are provided spaced apart along the second direction (the LED bead groups 112 arranged along the first direction form LED bead arrays 20). The light emission colors of the LED beads 1121 can be the same or different according to the actual application. Different light emission colors of LED beads 1121 can be used for different functions. For example, one LED bead array 20 can be used as a daytime running light, and another LED bead array 20 can be used as a turn signal. The same light emission color of LED beads 1121 can realize the brightness adjustment. Different brightness can be selected according to the usage environment (different brightness adjustments are realized by controlling the on and off of the LED bead array 20).

[0045] When adjacent LED beads 1121 (within the same LED bead group 112) have their orthographic projections on the projection plane λ overlapping to a minimum, the spacing between adjacent LED beads 1121 in the first direction is small, which also means that the spacing between adjacent LED bead arrays 20 in the first direction is small. When different LED bead arrays 20 are switched on, the illuminated area will not shift in the first direction, resulting in a good visual effect. When the spacing between adjacent LED beads 1121 in the first direction is large, the ends of adjacent LED bead arrays 20 (ends in the first direction) are also spaced further apart in the first direction. When different LED bead arrays 20 are switched on, the edges of the illuminated area (edges in the first direction) will shift as the switching (illuminating different LED bead arrays 20) occurs, resulting in a poor visual effect.

[0046] It should be noted that the surface of plate 111 is the surface with a larger area.

[0047] In some embodiments, in the same group of LED beads 112, the orthographic projections of adjacent LED beads 1121 on the projection plane λ partially overlap; in the first direction, the size of the LED bead 1121 is L1, and the size of the overlapping portion of adjacent LED beads 1121 is L2, satisfying: 1 / 2≤L2 / L1≤3 / 4.

[0048] When the value of L2 / L1 is less than 1 / 2, the spacing between adjacent LED beads 1121 in the first direction is large, which is not conducive to improving the visual effect. The specific analysis is similar to the aforementioned embodiment and will not be repeated here. When the value of L2 / L1 is greater than 3 / 4, the spacing between adjacent LED beads 1121 in the first direction is too small. The adjacent LED beads 1121 are too close to each other, which is not conducive to the wiring of each LED bead array 20. Moreover, the small spacing will affect the heat dissipation of adjacent LED beads 1121, thus affecting the overall heat dissipation effect.

[0049] Therefore, when the values ​​of L2 / L1 are within the above range, it can ensure good visual effects, facilitate the wiring of each LED array 20, and also facilitate the heat dissipation of LED 1121, thus improving its service life.

[0050] See Figure 3 and Figure 4On the other hand, this application also relates to a printed circuit board 10, which is divided into at least one light-emitting region 30, and the light-emitting region 30 is provided with at least one circuit board unit 11 as described above.

[0051] Based on the shape of the printed circuit board 10, the printed circuit board 10 can be divided into multiple light-emitting areas 30 (the area selected by the dashed lines in the figure does not represent the range of the light-emitting area 30; the light-emitting area 30 refers to the area covered by the circuit board unit 11 within the dashed lines). Each light-emitting area 30 is equipped with a circuit board unit 11. According to the shape of the light-emitting area 30, an appropriate number and size of circuit board units 11 can be selected, that is, the printed circuit board 10 is composed of multiple circuit board units 11. This can break down the complex printed circuit board 10 into multiple narrow and regular circuit board units 11, reducing the production difficulty of the printed circuit board 10 and thus reducing production costs. Moreover, the complex-shaped printed circuit board 10 (a single board) is easily damaged by external forces, which can be effectively avoided by splicing circuit board units 11. In addition, installing circuit board units 11 individually reduces assembly difficulty and improves production efficiency compared to installing the entire printed circuit board 10.

[0052] In some embodiments, in the light-emitting areas 30 with at least two circuit board units 11, the first direction of each circuit board unit 11 (i.e. the length extension direction of the circuit board unit 11 board body 111, i.e. the arrangement direction of the lamp bead group 112) is basically parallel, which is beneficial to the uniform spacing between the lamp bead groups 112 in the light-emitting areas 30 and to improving the overall lighting uniformity.

[0053] It should be noted that the light-emitting area 30 can be composed of multiple circuit board units 11 spliced ​​together, or it can be composed of a single circuit board unit 11, depending on the actual shape of the light-emitting area 30. In addition, the first direction is basically parallel, not just completely parallel. The included angle between the two first directions is β, which satisfies: 0°≤β≤10°, such as 0°, 5°, 10°, etc. The value of β within 10° is considered basically parallel and falls within the protection scope of this application.

[0054] In some embodiments, there are two light-emitting areas 30, referred to as the first area 100 and the second area 110; the line connecting the LED bead groups 112 of the circuit board unit 11 in the first area 100 is referred to as line a, and the line connecting the LED bead groups 112 of the circuit board unit 11 in the second area 110 is referred to as line b. The angle between line a and line b is θ, which satisfies: 90°≤θ<180°, such as 90°, 120°, 150°, etc.

[0055] The first area 100 and the second area 110 are set at a right angle or an obtuse angle, which can increase the illumination range. By dividing the printed circuit board 10 into two light-emitting areas 30, the production difficulty is reduced and material waste is minimized (when the printed circuit board 10 is processed as a single piece, the shape of the printed circuit board 10 needs to be engraved on a large, complete board material; this application divides the printed circuit board 10 into two light-emitting areas 30, which are processed separately, reducing board material waste). The angle can be selected according to the actual product to meet personalized design needs.

[0056] In some embodiments, one of the light-emitting areas 30 is provided with three circuit board units 11, which are spliced ​​together to form a triangular light-emitting area 30; the three circuit board units 11 are referred to as a first plate 40, a second plate 50, and a third plate 60; the first plate 40 and the third plate 60 are arranged at an angle and intersect to form a corner 90 (e.g., ...). Figure 3 From the perspective of the first plate 40 and the third plate 60, the tops of the first plate 40 and the third plate 60 are close to each other to form a sharp corner, so as to form an installation space 70 between the first plate 40 and the third plate 60, and the second plate 50 is accommodated in the installation space 70.

[0057] The triangular light-emitting area 30 formed can meet the personalized display requirements of vehicle lights. In other embodiments, the light-emitting area 30 can be set in other shapes, not limited to this. The second plate 50 is set within the angle range (i.e., the installation space 70) between the first plate 40 and the third plate 60, which is conducive to the stability of the installation of the second plate 50 and thus improves the lighting effect. Moreover, the first plate 40 and the third plate 60 define the installation position, which is conducive to the rapid positioning and installation of the second plate 50 and improves the assembly efficiency.

[0058] The first plate 40 has a dimension d1 in its first direction, and the third plate 60 has a dimension d2 in its first direction, satisfying d1 < d2; the first plate 40, the second plate 50, and the third plate 60 are basically flush at the end of the angle formed by the first plate 40 and the third plate 60 away from the first plate 40.

[0059] The length of the third board 60 is longer than the length of the first board 40, and the third board 60 is flush with the side of the first board 40 away from the included angle (the angle formed between the first board 40 and the third board 60), that is, on Figure 3 From the perspective of the first plate 40, a portion of the third plate 60 is provided at the top. The LED bead group 112 on this portion of the third plate 60 can illuminate the corners of the triangular light-emitting area 30, which helps to improve the overall uniformity of illumination. The area of ​​the triangular light-emitting area 30 located at the top of the first plate 40 is a narrow part of the triangular light-emitting area 30. Only a portion of the third plate 60 needs to be accommodated in this narrow part, compared to Figure 4The triangular light-emitting area 30 shown (the top of the light-emitting area 30 is spliced ​​from the first plate 40 and the third plate 60) in this application has only the third plate 60 at the top, which is narrower and conducive to the flattening and personalized design of the light-emitting area 30.

[0060] In addition, the sides of the first plate 40, the second plate 50, and the third plate 60 that are away from the included angle (the included angle formed between the first plate 40 and the third plate 60) are flush, making the light-emitting area 30 more regular and improving the visual effect.

[0061] In some embodiments, the third plate 60 includes a main body 61 and a mounting portion 62. The main body 61 is rectangular, and the mounting portion 62 extends toward the mounting space 70. The mounting portion 62 and the second plate 50 are arranged sequentially in a direction away from the corner 90.

[0062] like Figure 3 As shown, the mounting part 62 extends to the top of the second plate 50, that is, the mounting part 62 fills the top space of the second plate 50 (this space is the narrower area of ​​the angle formed by the first plate 40 and the third plate 60, that is, the end of the angle), which avoids the top of the second plate 50 being too sharp and avoids scratching people during use; at the same time, the main body 61 is rectangular and has a regular shape, which reduces the processing difficulty. The mounting part 62 extends to the mounting space 70, which is basically located in the middle of the third plate 60 in this embodiment. The mounting part 62 is used to install the third plate 60, which helps to improve the stability of the installation of the third plate 60.

[0063] It is worth mentioning that the third plate 60 is also provided with other fixed installation points, such as the relevant installation points at both ends of the length direction of the third plate 60, and not limited to this.

[0064] In some embodiments, the second plate 50 gradually increases in size in the direction away from the corner 90 in its second direction.

[0065] That is, the second plate 50 is arranged in a triangle, and the second plate 50 can fill the installation space 70 between the first plate 40 and the third plate 60 as much as possible, which helps to improve the overall installation stability.

[0066] See Figure 5 and Figure 6 On the other hand, this application also relates to an optical module, including any of the aforementioned printed circuit boards 10. The optical module also includes a reflector 80, which includes a plurality of reflectors 81, and the reflectors 81 correspond one-to-one with the lamp bead group 112.

[0067] On the other hand, this application also relates to a vehicle light, including the aforementioned optical module.

[0068] On the other hand, this application also relates to a vehicle including the aforementioned headlights.

[0069] By adopting the technical solution provided in this application embodiment, the complex printed circuit board 10 is divided into multiple narrow and regular circuit board units 11, thereby reducing production costs. The complex-shaped printed circuit board 10 (a single board) is easily damaged by external forces, which can be effectively avoided by splicing the circuit board units 11. In addition, installing the circuit board units 11 separately reduces the assembly difficulty and improves production efficiency compared to installing the entire printed circuit board 10. The adjacent LED beads 1121 are spaced smaller in the first direction, that is, the adjacent LED bead arrays 20 are spaced smaller in the first direction. When different LED bead arrays 20 are switched on, the illuminated area will not shift in the first direction, resulting in a good visual effect.

[0070] In the various embodiments of this application, unless otherwise specified or logically conflicting, the terminology or descriptions between different embodiments are consistent and can be referenced mutually. Technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships. In this application, "at least one" means one or more, and "more than one" means two or more.

The order of the process numbers described above does not imply the order of execution; the execution order of each process should be determined by its function and internal logic.

[0072] The circuit board unit, printed circuit board, optical module, vehicle lamp and vehicle provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application.
