Description
Technical Field
[0001] This utility model relates to the field of automotive lighting technology, and in particular to an optical thick-walled component and a vehicle lamp using the same. Background Technology
[0002] In lighting design, thick-walled optical components, as important parts for realizing the functions of signal lights, greatly influence the appearance of vehicle lights when illuminated. For example, CN222747133U discloses an optical structure and vehicle light with high luminous efficiency and uniformity, and CN222047477U discloses a multifunctional non-aluminized reflective thick-walled component structure, both of which use single horizontal windows for their thick-walled components.
[0003] Through practical use and research, the thick-walled components used in the aforementioned disclosed technology have the following problems: First, the lighting mode is limited to a single long banner window, without any dot matrix windows, and only supports lighting a single banner window, thus failing to achieve multiple lighting scene modes. Second, if complex lighting scene modes are represented by repeatedly using a single window structure, the cost is high, the space utilization is low, and the uniformity of light emission may be affected because the thick-walled components of each window are produced in different batches.
[0004] However, increasingly lower cost requirements and more diverse lighting appearance demands place higher demands on existing optical thick-walled component solutions. Therefore, designing a novel and diverse thick-walled component structure to achieve optical effects has become an urgent problem to be solved. Utility Model Content
[0005] The primary objective of this invention is to provide an optical thick-walled component to address the technical problem of achieving novel and diverse optical effects.
[0006] The second objective of this invention is to provide a vehicle lamp that solves the technical problem of satisfying the need for novel and diverse optical effects.
[0007] The optical thick-walled component of this invention is implemented as follows:
[0008] An optical thick-walled component, comprising:
[0009] The first thick-walled main body includes a flat body and a long strip-shaped first light-emitting surface disposed on one side end face of the flat body; and the end face of the flat body facing away from the first light-emitting surface is designed as a first light-incident surface.
[0010] The second thick-walled body includes a plurality of thick-walled portions protruding from the top surface of the flat body and extending along the length direction of the first light-emitting surface; the plurality of thick-walled portions are arranged at intervals; each thick-walled portion has a second light-emitting surface parallel to the first light-emitting surface, and the end face of each thick-walled portion facing away from the second light-emitting surface is designed as a second light-incident surface.
[0011] In an optional embodiment of this invention, the second light-emitting surfaces of the plurality of thick-walled portions are on the same horizontal plane.

[0014] In an optional embodiment of this utility model, a thick-walled connecting member is further provided between each of the second thick-walled main bodies and the first thick-walled main body;
[0015] Both the first thick-walled body and the second thick-walled body are made of light-transmitting material; and
[0016] The thick-walled connector is made of a non-transparent material.
[0017] In an optional embodiment of this utility model, the first thick-walled main body, the second thick-walled main body, and the thick-walled connecting member are integrally injection molded.
[0018] In an optional embodiment of this utility model, optical patterns are designed on both the first light-emitting surface and each of the second light-emitting surfaces.
[0019] The vehicle light of this utility model is implemented as follows:
[0020] A vehicle headlight includes: the aforementioned thick-walled optical component, and a circuit board disposed on one side of the first light-incident surface and the second light-incident surface of the thick-walled optical component; wherein...
[0021] The circuit board is designed with a first light source component corresponding to the first light incident surface and a second light source component corresponding to multiple second light incident surfaces.
[0022] In an optional embodiment of this utility model, the vehicle lamp further includes a decorative ring fitted over the outer layer of the optical thick-walled component;
[0023] The decorative ring has a receiving cavity suitable for inserting a thick-walled optical component, and its outer side wall is provided with a first light-emitting hole adapted to a first light-emitting surface and a plurality of second light-emitting holes adapted one-to-one to a plurality of second light-emitting surfaces; and
[0024] The multiple second light-emitting holes are all located above the first light-emitting hole.
[0025] In an optional embodiment of this invention, the decorative ring is made of a non-transparent material.
[0026] By adopting the above technical solution, this utility model has the following beneficial effects: The optical thick-walled component of this utility model and the vehicle lamp using it, through the dot matrix second light-emitting surface on the second thick-walled main body and the first light-emitting surface in the form of a long horizontal window on the first thick-walled main body, can support the lighting and signal light functions to achieve multiple lighting modes, improving the adaptability to different usage scenarios; on the other hand, it does not require the repeated use of the same thick-walled component structure to achieve complex shapes, resulting in low cost, high space utilization, and guaranteed light emission uniformity.

Detailed Implementation
[0033] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0034] Example 1:
[0035] Please see Figures 1 to 5 As shown, this embodiment provides an optical thick-walled component, including: a first thick-walled body 3 and a second thick-walled body 1 used in conjunction.
[0036] Specifically, the first thick-walled main body 3 includes a flat body and a long, narrow first light-emitting surface 31 located on one side end of the flat body; the end face of the flat body facing away from the first light-emitting surface 31 is designed as a first light-incident surface 32. In this structure, the first light-emitting surface 31 is shaped like a long, horizontal window. It should be noted that the general shape of the first light-incident surface 32 is adapted to the first light-emitting surface 31, also being a long, horizontal window. Regarding the width dimensions of the first light-incident surface 32 and the first light-emitting surface 31, their width dimensions can be the same or different. Generally, the width dimension of the first light-emitting surface 31 is slightly smaller than the width dimension of the first light-incident surface 32.
[0037] Secondly, there is the second thick-walled body 1, which includes a plurality of thick-walled portions protruding from the top surface of the flat body and extending along the length of the first light-emitting surface 31. These thick-walled portions are spaced apart, meaning that a gap is formed between each pair of adjacent thick-walled portions. Referring to the accompanying drawings, in one optional embodiment, the plurality of thick-walled portions are all located on the edge of the top surface of the flat body near the first light-incident surface 32, and each thick-walled portion protrudes from the top surface of the flat body by a certain height. Preferably, from the perspective of ease of processing, the plurality of thick-walled portions here adopt the same structure, and the spacing between each pair of adjacent thick-walled portions is the same.
[0038] Based on the above structure, each thick-walled portion has a second light-emitting surface 11 parallel to the first light-emitting surface 31, and the end face of each thick-walled portion facing away from the second light-emitting surface 11 is designed as a second light-incident surface 12. Here, assuming that the structures of multiple thick-walled portions are identical, the second light-emitting surfaces 11 of the multiple thick-walled portions are on the same horizontal plane. Alternatively, in one embodiment, all the multiple second light-incident surfaces 12 are on the same horizontal plane as the first light-incident surface 32.
[0039] Furthermore, in one specific optional implementation, a thick-walled connector 2 is provided between each second thick-walled body 1 and the first thick-walled body 3. Both the first thick-walled body 3 and the second thick-walled body 1 are made of a light-transmitting material, and the color can be transparent or milky white. The thick-walled connector 2 is made of a non-light-transmitting material, and the color can be black or gray. This design of the thick-walled connector 2 prevents light from passing between the first thick-walled body 3 and the second thick-walled body 1.
[0040] Based on the above structure, from a manufacturing process perspective, the first thick-walled main body 3, the second thick-walled main body 1, and the thick-walled connecting piece 2 are integrally injection molded. It should be noted that multiple second thick-walled main bodies 1 can be connected to the first thick-walled main body 3 via a long, strip-shaped thick-walled connecting piece 2 parallel to the first light-emitting surface 31, or one second thick-walled main body 1 can correspond to one thick-walled connecting piece 2. This means that a gap is formed between every two adjacent thick-walled connecting pieces 2. Preferably, the structures of the multiple thick-walled connecting pieces 2 corresponding to multiple second thick-walled main bodies 1 are identical, thus ensuring that multiple second light-emitting surfaces 11 are on the same horizontal line and parallel to the first light-emitting surface 31. Both of these different implementations meet the usage requirements of this embodiment.
[0041] Finally, it is necessary to note that both the first light-emitting surface 31 and each of the second light-emitting surfaces 11 are designed with optical patterns. The specific structure of the optical patterns on the first light-emitting surface 31 and the second light-emitting surface 11 can be the same or different; this embodiment does not impose an absolute limitation on this. The design of the optical patterns can effectively improve the uniformity of light emission.
[0042] In summary, for the optical thick-walled component of this embodiment, by using the dot-matrix second light-emitting surface 11 on the second thick-walled body 1 in conjunction with the long horizontal window-shaped first light-emitting surface 31 on the first thick-walled body 3, it can support the lighting function of lamps and signal lights to achieve multiple lighting modes and improve the adaptability to different usage scenarios. On the other hand, it does not require the repeated use of the same thick-walled component structure to achieve complex shapes, resulting in low cost, high space utilization, and guaranteed light emission uniformity.
[0043] Example 2:
[0044] Please see Figures 1 to 5 As shown, based on the optical thick-walled component of Embodiment 1, this embodiment provides a vehicle lamp, including: the optical thick-walled component of Embodiment 1, and a circuit board 5 disposed on one side of the first light-incident surface 32 and the second light-incident surface 12 of the optical thick-walled component.
[0045] The circuit board 5 is designed with a first light source assembly 7 corresponding to the first light-incident surface 32 and a second light source assembly 6 corresponding to multiple second light-incident surfaces 12. It should be noted that the first light source assembly 7 can be multiple light-emitting devices arranged in an array along a straight line; the second light source assembly 6 is a multiple light-emitting devices arranged in an array that can be distributed one-to-one with the second light-incident surfaces 12 of multiple second thick-walled bodies 1.
[0046] Based on the above structure, it should also be noted that the headlight in this embodiment further includes a decorative ring 4 fitted over the outer layer of the optical thick-walled component; the decorative ring 4 is made of a non-transparent material, such as, but not limited to, black material. The decorative ring 4 has a receiving cavity suitable for the insertion of the optical thick-walled component, and on the outer wall of the decorative ring 4 are provided a first light-emitting hole 41 adapted to the first light-emitting surface 31 and a plurality of second light-emitting holes 42 adapted one-to-one to a plurality of second light-emitting surfaces 11; and the plurality of second light-emitting holes 42 are all located above the first light-emitting hole 41.
[0047] In summary, for the vehicle lights of this embodiment, by controlling the number and position of the light-emitting devices in the first light source assembly 7 and the second light source assembly 6, multiple lighting modes (such as...) can be achieved. Figure 5 The blacked-out areas in the shown ad are the highlighted areas, allowing for flexible use.
