Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and more specifically, to a lighting device and vehicle that solves the problem of crosstalk in a matrix-type light output port. Background Technology

[0002] With the development of science and technology, today's consumers' demands for vehicle lights are no longer limited to basic lighting and signaling functions. More stylish designs and diverse interactive functions are more attractive to consumers. As a result, matrix signal light designs with interactive features and avant-garde aesthetics have emerged.

[0003] However, the related technology has at least one of the following problems: the multiple propagating elements in the thick-walled component of the related technology are set as one unit, which will cause light crosstalk between the light outlets of two adjacent propagating elements on the thick-walled component when the light outputs light to the propagating element. Utility Model Content

[0004] The technical problem solved by this utility model is that in the related technology, the propagation element in the thick-walled body is set as a whole, which will cause light crosstalk between the light outlets of two adjacent propagation elements on the thick-walled body when the light is output to the propagation element.

[0005] To solve the above problems, this utility model provides a lighting device for solving the problem of crosstalk in matrix-type light output ports, comprising: a housing, the housing having an installation space, and a plurality of light output ports on one side of the housing; the plurality of light output ports are spaced apart and connect the installation space to the outside of the housing; a thick-walled member, the thick-walled member being disposed within the installation space, the thick-walled member having a plurality of first propagation elements and a plurality of second propagation elements; the plurality of first propagation elements and the plurality of second propagation elements are spaced apart and correspond to the plurality of light output ports.

[0006] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: Compared with the multiple propagation elements of the thick-walled component in the related technology being set as one unit, this application provides a clear path for the propagation and emission of light by splitting the thick-walled component into multiple independent first propagation elements and second propagation elements, which helps to optimize the propagation direction and emission angle of light. Furthermore, the multiple first propagation elements and multiple second propagation elements correspond to the light outlet, and there is a gap between different propagation elements to reduce the mutual interference of light between adjacent propagation elements, making the light emitted from each light outlet more independent, thereby better controlling the light emission effect of the lighting device.

[0007] In one embodiment of this utility model, the thick-walled component further includes: a plurality of first connecting members, which are disposed between two adjacent first propagating members and connect the two adjacent first propagating members to form at least one first thick-walled body; a plurality of second connecting members, which are disposed between two adjacent second propagating members and connect the two adjacent second propagating members to form at least one second thick-walled body; wherein, the thick-walled component is formed by splicing at least one first thick-walled body and at least one second thick-walled body.

[0008] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: the first connector connects two adjacent first propagation components to form a first thick-walled body, so that multiple first propagation components form a stable overall structure; the second connector connects two adjacent second propagation components to form a second thick-walled body, so that multiple second propagation components form a stable overall structure; and the thick-walled component is formed by splicing at least one first thick-walled body and at least one second thick-walled body, which facilitates the manufacturing and assembly process of the thick-walled component and reduces the difficulty of production and manufacturing.

[0009] In one embodiment of this utility model, the splicing includes a nested arrangement.

[0010] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the nested arrangement of thick-walled bodies not only further enhances the stability and efficiency of the overall structure of the thick-walled bodies, but also makes the splicing structure more compact, reduces assembly space, and improves space utilization.

[0011] In one embodiment of this utility model, the thick-walled component further includes: a plurality of first mating holes formed by a plurality of first connecting members and a plurality of first propagating members; and a plurality of second mating holes formed by a plurality of second connecting members and a plurality of second propagating members; wherein the first mating holes and the second mating holes enable the first thick-walled body and the second thick-walled body to be nested together.

[0012] Compared with existing technologies, the technical effects achieved by this solution are as follows: the first connector and the first propagator form a first mating hole, which means that there is a large gap between two adjacent first propagators; similarly, there is also a large gap between two adjacent second propagators. This makes the connection between the first and second thick-walled bodies more stable when they are embedded and spliced, making the overall structure of the thick-walled component more compact, and helping to ensure the relative positional accuracy between each propagator, thus ensuring the stability of the light propagation path. On the other hand, by increasing the distance between adjacent propagators, the crosstalk of light in the thick-walled component can be further reduced, and it is also beneficial to design the processing mold of the thick-walled component, thus improving the mold feasibility.

[0013] In one embodiment of this utility model, the thick-walled component further includes: a first base surface formed by the cooperation of a plurality of first connectors; a second base surface formed by the cooperation of a plurality of second connectors; the first base surface and the second base surface are arranged adjacent to each other.

[0014] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: a base surface is set on both the first thick-walled body and the second thick-walled body, and the two base surfaces are set adjacent to each other. This provides a clear structural interface for the thick-walled parts. In addition, during the assembly of the thick-walled parts, the first base surface and the second base surface can be used as reference surfaces for positioning and assembly, avoiding interference during assembly.

[0015] In one embodiment of this utility model, both the first and second propagating elements are provided with draft angles.

[0016] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: the setting of the draft angle facilitates the smooth ejection of the propagating component from the mold and reduces the demolding resistance; combined with the first mating hole and the second mating hole, the first thick-walled body and the second thick-walled body can facilitate demolding while meeting the length of the propagating component.

[0017] In one embodiment of this utility model, the first propagating element and the second propagating element have the same structure.

[0018] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the first and second propagation components have the same structure, which reduces the types of parts and lowers the mold development cost.

[0019] In one embodiment of this utility model, it further includes: a light-emitting element, which is disposed on the side of the thick-walled member away from the light outlet.

[0020] Compared with existing technologies, the technical effect achieved by this technical solution is that the light-emitting element is located on the side of the thick-walled component away from the light outlet, so that the light can be effectively transmitted and distributed through the propagation element inside the thick-walled component, providing a stable light source output for the lighting device.

[0021] In one embodiment of this utility model, the housing is composed of a shielding member and a base plate arranged opposite to each other; a thick-walled member is located between the shielding member and the base plate; a light-emitting member is located on the side of the base plate near the thick-walled member; and multiple light-emitting ports are located on the shielding member.

[0022] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the thick-walled component is placed between the shielding component and the base plate, so that the shielding component can block some of the stray light emitted from the thick-walled component, preventing the light from scattering randomly, making the light emitted from the light outlet more concentrated and orderly, and further improving the light output effect of the light.

[0023] In one embodiment of this utility model, a vehicle is also provided, including the lighting device of any of the above embodiments.

[0024] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: it can achieve the technical effects corresponding to any of the above examples, which will not be elaborated here.

[0025] By adopting the technical solution of this utility model, the following technical effects can be achieved:

[0026] (1) This application provides a clear path for the propagation and emission of light by splitting the thick-walled component into multiple independent first propagation components and second propagation components, which helps to optimize the propagation direction and emission angle of light. Furthermore, multiple first propagation components and multiple second propagation components correspond to the light outlet, and there is a gap between different propagation components to reduce the mutual interference of light between adjacent propagation components, so that the light emitted from each light outlet is more independent, thereby better controlling the light emission effect of the lighting device.

[0027] (2) The first connecting member and the first propagating member form a first mating hole, which means that there is a large gap between two adjacent first propagating members; similarly, there is also a large gap between two adjacent second propagating members; this makes the connection between the first thick-walled body and the second thick-walled body more stable when they are embedded and spliced, making the overall structure of the thick-walled member more compact, and is conducive to ensuring the relative position accuracy between each propagating member and ensuring the stability of the light propagation path; on the other hand, by increasing the distance between adjacent propagating members, the cross-lighting of the thick-walled member can be further reduced, and it is also conducive to designing the processing mold of the thick-walled member, improving the mold feasibility;

[0028] (3) A base surface is set on both the first thick-walled body and the second thick-walled body, and the two base surfaces are set adjacent to each other. This provides a clear structural interface for the thick-walled parts. In the process of assembling the thick-walled parts, the first base surface and the second base surface can be used as reference surfaces for positioning and assembly, avoiding interference during assembly.

Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0042] 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 link, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0044] See Figure 1 , Figure 1 A schematic diagram of a lighting device for solving the problem of crosstalk at a matrix-type light output port, provided by an embodiment of this utility model; combined with Figures 2 to 9 Specifically, a lighting device 100 for solving the problem of crosstalk in a matrix-type light output port includes: a housing 10 and a thick-walled member 20; wherein, the housing 10 is provided with an installation space 13, and a plurality of light output ports 14 are provided on one side of the housing 10; the plurality of light output ports 14 are spaced apart and connect the installation space 13 to the outside of the housing 10; the thick-walled member 20 is disposed in the installation space 13, and the thick-walled member 20 is provided with a plurality of first propagation elements 211 and a plurality of second propagation elements 221; the plurality of first propagation elements 211 and the plurality of second propagation elements 221 are spaced apart and correspond to the plurality of light output ports 14.

[0045] Based on specific usage, the thick-walled component 20 is divided into multiple first propagation components 211 and multiple second propagation components 221, providing a clear path for the propagation and refraction of light. Furthermore, the first propagation components 211 and the second propagation components 221 are arranged in an alternating manner, making each propagation component relatively independent, which reduces mutual interference between adjacent propagation components. On the basis of the relative independence of each propagation component, each first propagation component 211 and the second propagation component 221 corresponds to a light outlet 14, which makes the light emitted from each light outlet 14 purer and allows for better control of the light output effect of the lighting device 100.

[0046] Preferably, the first propagating element 211 and the second propagating element 221 are identical in structure and shape.

[0047] For further information, please refer to [link / reference]. Figure 4 and Figure 5The thick-walled component 20 further includes: a plurality of first connectors 212 and a plurality of second connectors 222; wherein, the first connectors 212 are disposed between two adjacent first propagation components 211 and connect the two adjacent first propagation components 211, and cooperate to form at least one first thick-walled body 21; the second connectors 222 are disposed between two adjacent second propagation components 221 and connect the two adjacent second propagation components 221, and cooperate to form at least one second thick-walled body 22; wherein, the thick-walled component 20 is formed by splicing at least one first thick-walled body 21 and at least one second thick-walled body 22.

[0048] It should be noted that this application does not limit the number of parts that the thick-walled component 20 can be divided into. The purpose of dividing the thick-walled component 20 into the first thick-walled body 21 and the second thick-walled body 22 is to understand the idea of ​​dividing the thick-walled component 20 in this application. The thick-walled component 20 can also be divided into the first thick-walled body 21, the second thick-walled body 22, the third thick-walled body, etc.

[0049] Preferably, the number of thick-walled members 20 is at least one.

[0050] Preferably, when there are multiple thick-walled components 20, each thick-walled component 20 is independent of the others to prevent light leakage between adjacent thick-walled components 20.

[0051] It should be noted that, apart from the difference in naming, the first thick-walled body 21 and the second thick-walled body 22 have the same structure, shape and function.

[0052] Preferably, the splicing includes nested arrangements.

[0053] For further information, please refer to [link / reference]. Figure 6 and Figure 7 The thick-walled member 20 further includes: a plurality of first mating holes 213 formed by a plurality of first connectors 212 and a plurality of first propagators 211, and a plurality of second mating holes 223 formed by a plurality of second connectors 222 and a plurality of second propagators 221; wherein the first mating holes 213 and the second mating holes 223 enable the first thick-walled body 21 and the second thick-walled body 22 to be nested together; specifically, at least a portion of the structure of the first thick-walled body 21 is embedded in the plurality of second mating holes 223, and at least a portion of the structure of the second thick-walled body 22 is embedded in the plurality of first mating holes 213.

[0054] In specific applications, since the first propagator 211 and the second propagator 221 are spaced apart, it can be understood that there is a certain distance between them. Based on this, multiple first propagators 211 are connected by the first connector 212 to form a first mating hole 213 for embedding the second propagator 221. This changes the distance between two adjacent propagators from the first propagator 211 to the second propagator 221 to the first propagator 211 to another first propagator 211 that is far away from the second propagator 221. This makes the distance between two adjacent first propagators 211 in the first thick-walled body 21 larger, which is beneficial for the design of the mold of the first thick-walled body 21. Moreover, when the distance is larger, it can further prevent light leakage between two adjacent first propagators 211 in the first thick-walled body 21. Similarly, connecting multiple second propagators 221 by the second connector 222 to form a second mating hole 223 for embedding the first propagator 211 has the same effect as above, and will not be elaborated further here.

[0055] Furthermore, please refer to Figure 9 Since the distance between two adjacent propagating elements in the first thick-walled body 21 and the second thick-walled body 22 is larger after splitting, the length of the first propagating element 211 and the second propagating element 221 can be longer, resulting in better light uniformity and facilitating the construction of the thick-walled body mold structure.

[0056] For further information, please refer to [link / reference]. Figure 8 The thick-walled component 20 further includes: a first base surface 214 formed by the cooperation of a plurality of first connectors 212; a second base surface 224 formed by the cooperation of a plurality of second connectors 222; the first base surface 214 and the second base surface 224 are arranged adjacent to each other.

[0057] In a specific example, multiple first propagating elements 211 are connected by multiple first connecting elements 212 to form a first thick-walled body 21, and the multiple first connecting elements 212 also form a first base surface 214; similarly, multiple second connecting elements 222 also form a second base surface 224; the first base surface 214 and the second base surface 224 are arranged adjacent to each other. For example, the first base surface 214 is arranged along the length direction of the first propagating element 211 and is located at a first height, and the second base surface 224 is arranged along the length direction of the second propagating element 221 and is located at a second height; wherein the second height is greater than or less than the first height, so that the first base surface 214 and the second base surface 224 are arranged one in front of the other, avoiding interference between the first thick-walled body 21 and the second thick-walled body 22 during assembly.

[0058] Furthermore, both the first propagating element 211 and the second propagating element 221 are provided with draft angles; based on the larger distance between two adjacent propagating elements in the first thick-walled body 21 and the second thick-walled body 22 after splitting, draft angles are provided for the first propagating element 211 and the second propagating element 221, making it easier for the first thick-walled body 21 and the second thick-walled body 22 to be demolded during processing.

[0059] Furthermore, the lighting device 100 also includes a light-emitting element 30, which is located on the side of the thick-walled member 20 away from the light outlet 14, so that the light can be effectively transmitted and distributed through the propagation element in the thick-walled member 20, providing a stable light source output for the lighting device 100.

[0060] Furthermore, the housing 10 is composed of a shielding member 11 and a base plate 12 arranged opposite to each other; the thick-walled member 20 is located between the shielding member 11 and the base plate 12; the light-emitting member 30 is located on the side of the base plate 12 near the thick-walled member 20; multiple light-emitting ports 14 are all located on the shielding member 11, so that the observed light is emitted from the light-emitting ports 14 of the shielding member 11, and the other structures of the thick-walled member 20 are hidden below the shielding member 11, further preventing the occurrence of light crosstalk problems.

[0061] Furthermore, this utility model also provides a vehicle including the lighting device 100 in any of the above examples.

[0062] Although the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
