[0001] This application belongs to the technical field of automotive lighting, and particularly relates to an optical component, automotive lighting, and vehicle. Background Technology

[0002] Currently, different light functions in automotive lighting are typically provided independently, occupying a significant amount of layout space. To improve the spatial layout of automotive lighting, there are solutions that utilize the same light-emitting surface to emit different light functions. However, current solutions do not consider the different lighting requirements of different light functions.

[0003] Therefore, how to improve the spatial layout of automotive lights while meeting the lighting requirements of different light functions is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this application is to provide an optical component, automotive lighting fixture, and vehicle that improves the spatial layout of automotive lighting fixtures while meeting the lighting requirements of different light functions.

[0005] To solve the above problems, the technical solution of this application is as follows: An optical component, comprising: A first light guide element includes a plurality of first light-incident ends, a plurality of second light-incident ends, and at least one first light-outcident end.

[0008] According to one embodiment of this application, the first light guide element further includes at least one first reflective surface. Light rays incident on the first light guide element from the first light-incident end and the second light-incident end are reflected by the at least one first reflective surface and then emitted from the first light-out end.

[0011] According to one embodiment of this application, the second light guide element further includes at least one second reflective surface, and light rays incident on the second light guide element from the third light incident end are reflected by the at least one second reflective surface and then emitted from the second light emitting end.

Detailed Implementation

[0018] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed description of an optical component, automotive lighting fixture, and vehicle according to this application. The advantages and features of this application will become more apparent from the following description and claims.

[0019] The term "comprising" and its variations as used herein are open-ended inclusions, meaning "including but not limited to". The term "based on" means "at least partially based on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Definitions of other terms will be given in the description below.

[0020] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "installation" and "connection" 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 direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of 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.

[0021] The use of the terms "first" and "second" in this article is only for distinguishing components and does not impose any restrictions on the structure or location of the components.

[0022] Please refer to Figures 1 to 3 This embodiment provides an optical component. The optical component includes a first light guide element 10. The first light guide element 10 includes a plurality of first light-incident ends 11, a plurality of second light-incident ends 12, and at least one first light-outceasing end 13. Light incident via the first light-incident ends 11 exits from the first light-outceasing end 13 to provide a first optical function. Light incident via the second light-incident ends 12 exits from the first light-outceasing end 13 to provide a second optical function. The arrangement density of the first light-incident ends 11 is different from the arrangement density of the second light-incident ends 12, and the first optical function is different from the second optical function.

[0023] This optical component emits different light functions from the same light-emitting end, without requiring a large layout space, which can improve the layout of vehicle lights; at the same time, the different arrangement density of the first light-incident end 11 compared to the second light-incident end 12 can meet the lighting requirements of different first and second light functions.

[0024] In one embodiment, the first light-incident end 11 is arranged along a first direction, and the second light-incident end 12 is arranged along the first direction. That is, the first light-incident end 11 and the second light-incident end 12 are arranged in the same direction. However, since actual optical components usually need to meet the layout space and light-emitting shape trends when in use, the arrangement direction of the first light-incident end 11 and the second light-incident end 12 may not be a straight line. In this case, the arrangement of the first light-incident end 11 along the first direction and the arrangement of the second light-incident end 12 along the first direction can mean that the first light-incident end 11 and the second light-incident end 12 have the same or similar arrangement trends. This application is not intended to limit this.

[0025] In one embodiment, the first light-incident end 11 and the second light-incident end 12 form two light-incident ends, such as Figure 2 As shown. In some variations, the first light-receiving end 11 and the second light-receiving end 12 are alternately arranged. That is, the first light-receiving end 11 and the second light-receiving end 12 can be located in the same column, and the first light-receiving end 11 and the second light-receiving end 12 are arranged alternately. Since the arrangement density of the first light-receiving end 11 and the second light-receiving end 12 is different, the alternating arrangement of the first light-receiving end 11 and the second light-receiving end 12 can be, for example, two first light-receiving ends 11, one second light-receiving end 12, two first light-receiving ends 11, one second light-receiving end 12, and so on. This application is not limited to this, and other alternating arrangements are also within the protection scope of this application. The light-receiving directions of the first light-receiving end 11 and the second light-receiving end 12 can be the same or opposite. Figure 3 As shown, the light incident directions of the first light-incident end 11 and the second light-incident end 12 are the same. Therefore, the light sources corresponding to the first light-incident end 11 and the second light-incident end 12 are located on the same side of the first light guide element 10, and the first light-incident end 11 and the second light-incident end 12 can share the same circuit board for mounting the light source. In some other embodiments, for the sake of the lamp layout, the light incident directions of the first light-incident end 11 and the second light-incident end 12 may be opposite, but this application is not limited to this.

[0026] In one embodiment, the first light-incident end 11 and the second light-incident end 12 are light concentrators. Further, the first light guide element 10 is preferably a dual-color light concentrator, integrally molded from a transparent material and a high-reflectivity material using dual-color injection molding.

[0027] Specifically, the density of the first light-incident end 11 differs from the density of the second light-incident end 12 to meet the lighting requirements of different first and second light functions. Taking a turn signal as the first light function and a position light as the second light function as the second light function, for example, the first light-incident end 11 might use an amber-colored first light source 14 for the turn signal; the second light-incident end 12 might use a red / white second light source 15 for the position light. Since the uniformity requirement for turn signals is lower than that for position lights, the density of the first light-incident end 11 can be less than that of the second light-incident end 12. This is reflected in the number of first light sources 14 / first light-incident ends 11 being less than the number of second light sources 15 / second light-incident ends 12. The aforementioned light sources can be LEDs, lasers, or other light sources; this application is not limited to these.

[0028] In one embodiment, the first light guide element 10 further includes at least one first reflective surface 16. Light rays incident on the first light guide element 10 from the first light-incident end 11 and the second light-incident end 12 are reflected by the at least one first reflective surface 16 and then exited from the first light-exiting end 13. In this embodiment, the first light guide element 10 utilizes the optical form of the reflective surface of the light guide element to control the propagation direction of the light. Furthermore, one or more of the light-incident end, reflective surface, and light-exiting end of the first light guide element 10 can be provided with uniform light patterns to achieve a uniform light effect. Furthermore, the first light guide element 10 can be in the form of a thick wall, for example, a reflective thick wall. This application is not limited to this, and other forms of the first light guide element 10 are also within the scope of protection of this application.

[0029] In one embodiment, the optical component further includes a second light guide element 20. The second light guide element 20 includes a plurality of third light-incident ends 22 and at least one second light-outcident end 21. Light incident via the third light-incident ends 22 is emitted from the second light-outcident end 21 to provide a third optical function. The third optical function is different from both the first and second optical functions; or, the third optical function is the same as the first / second optical function.

[0030] It is understood that the second light guide element 20 has a similar structure to the first light guide element 10. The second light guide element 20 may correspond only to the third light entrance end 22, which realizes the third light function. The third light entrance end 22 may also be a condenser. The third light function realized by the light incident through the third light entrance end 22 and emitted from the second light exit end 21 may be the same as or different from the first / second light function. For example, if the first / second light function is manifested as a turn signal / position light, then the third light function may be one of the turn signal and position light, or it may be a brake light. This application is not limited to this.

[0031] In one embodiment, the second light guide element 20 further includes at least one second reflective surface 23. Light rays incident on the second light guide element 20 from the third light incident end 22 are reflected by the at least one second reflective surface 23 and then exited from the second light emitting end 21. That is, the second light guide element 20 is similar to the first light guide element 10, also utilizing the optical form of the reflective surface of the light guide element to control the propagation direction of the light. Furthermore, one or more of the light incident end, reflective surface, and light emitting end of the second light guide element 20 can be provided with uniform light patterns to achieve a uniform light effect, which will not be elaborated further here.

[0032] In one embodiment, the first light guide element 10 and the second light guide element 20 can be connected as a single unit to achieve the integration of more optical functions. For example... Figure 1 As shown, the first light guide element 10 and the second light guide element 20 are fixedly connected to form a whole. The first light source 14 and the second light source 15 are soldered onto the circuit board assembly 30, which is then heat-pressed onto the first light guide element 10.

[0033] In summary, this optical component integrates light-incident ends with varying densities through a single light-guiding element, allowing light rays with different functions to be multiplexed from the same light-out end. This enables multifunctional integration within a limited space and allows for resource allocation to be matched according to the varying optical uniformity requirements of each function, thereby improving the quality of light emission and design flexibility.

[0034] Based on the aforementioned optical components, this application provides an automotive lighting fixture, comprising: the aforementioned optical components; a first light source disposed relative to a first light-incident end; and a second light source disposed relative to a second light-incident end.

[0035] The automotive lighting fixture has the beneficial effects of the aforementioned optical components, which will not be elaborated upon here.

[0036] Furthermore, this application also provides a vehicle including the automotive lamp, having the same technical effects as the automotive lamp.

[0037] The embodiments of this application have been described in detail above with reference to the accompanying drawings, but this application is not limited to the above embodiments. Even if various changes are made to this application, if these changes fall within the scope of the claims of this application and their equivalents, they shall still fall within the protection scope of this application.
