Description

A first optical element, vehicle lamps, and a vehicle Technical Field

[0001] This application belongs to the field of automotive lighting technology, and particularly relates to a first optical element, vehicle lamps, and a vehicle. Background Technology

[0002] Vehicle lighting fixtures are used both inside and outside the vehicle to provide illumination, create ambiance, and provide signal indications, playing a crucial role in driving safety and the driving experience. In recent years, thick-walled light guide technology has been widely adopted in vehicle lighting. These thick-walled light guides have a miniature optical surface on the side furthest from the mounting surface, which guides the light emitted by the light source, forming a uniformly illuminated strip-shaped light-emitting surface. However, as thick-walled light guides, their illumination pattern is generally a strip-shaped light-emitting surface, resulting in a relatively simple effect.

[0015] Optionally, it also includes a first sidewall and / or a second sidewall parallel to the light rays projected onto the first light-emitting surface.

[0016] The light rays incident on the first optical element through the light-incident portion are reflected by the first sub-reflecting surface and then reflected by the first sidewall and / or the second sidewall to form a portion of the light rays projected onto the first light-emitting surface.

Detailed Implementation

[0043] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0044] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one"; "first" and "second" do not imply any ordering, and are only used for naming distinction.

[0045] This application provides a first optical element 1. Referring to Figures 1 to 17, an embodiment of the first optical element 1 provided by this application includes at least a light-incident portion 11, a first light-emitting surface 12, and a second light-emitting surface 13. A portion of the light rays incident on the first optical element 1 through the light-incident portion 11 exits from the first light-emitting surface 12, and another portion of the light rays incident on the first optical element 1 through the light-incident portion 11 exits from the second light-emitting surface 13. The first light-emitting surface 12 and the second light-emitting surface 13 form an angle, such that the light rays exiting from the first light-emitting surface 12 and the light rays exiting from the second light-emitting surface 13 form an angle, and the light rays exiting from the second light-emitting surface 13 are used to illuminate the second optical element 2, so as to form a different illuminated area from the first light-emitting surface 12.

[0046] The first-level optical element of this application can form two light-emitting surfaces (i.e., the first light-emitting surface 12 and the second light-emitting surface 13) by forming only one first optical element 1, which can form different lighting areas. When applied to vehicle lights, it can flexibly meet the different lighting requirements of vehicle lights.

[0047] The specific structure of the first optical element 1 provided in one embodiment of this application will be further described below.

[0048] Specifically, the first optical element 1 may be a thick-walled component, but this application is not limited thereto.

[0049] For ease of description, the lighting effect formed by a portion of the light rays that enter the first optical element 1 through the light-incident section 11 and exit from the first light-exiting surface 12 is called the first lighting effect, and the lighting effect formed by another portion of the light rays that enter the first optical element 1 through the light-incident section 11 and exit from the second light-exiting surface 13 (for example, after exiting, they illuminate the second optical element 2) is called the second lighting effect.

[0050] The first optical element 1 also includes a first reflective surface 14. Light rays incident on the first optical element 1 via the light-incident portion 11 are reflected by the first reflective surface 14, forming light rays that are partially projected onto the first light-emitting surface 12 and partially projected onto the second light-emitting surface 13. In other words, light rays incident on the first optical element 1 via the light-incident portion 11 can be split by the first reflective surface 14, so that part of the light rays are projected onto the first light-emitting surface 12 and part onto the second light-emitting surface 13. The beam-splitting structure of the reflective surface is relatively simple and easy to manufacture. Beam splitting within the first optical element 1 via the first reflective surface 14 allows for flexible application to different lighting scenarios at a lower cost.

[0051] Specifically, in some embodiments, the first reflecting surface 14 includes a first sub-reflecting surface 141 and a second sub-reflecting surface 142. Light rays incident on the first optical element 1 via the light-incident portion 11 are reflected by the first sub-reflecting surface 141 to form light rays partially projected onto the first light-emitting surface 12; light rays incident on the first optical element 1 via the light-incident portion 11 are reflected by the second sub-reflecting surface 142 to form light rays partially projected onto the second light-emitting surface 13.

[0052] The sub-reflecting surfaces (i.e., the first sub-reflecting surface 141 and the second sub-reflecting surface 142) can be planar (planar sub-reflecting surfaces are easier to manufacture) or curved (curved sub-reflecting surfaces can converge light rays and improve light emission efficiency). For example, the first sub-reflecting surface 141 and the second sub-reflecting surface 142 can both be planar, or both can be planar and curved, or one of the first sub-reflecting surfaces 141 and the second sub-reflecting surface 142 can be planar and the other can be curved, etc. This application can achieve many more variations, which will not be elaborated here.

[0053] In some embodiments, the first sub-reflective surface 141 and the second sub-reflective surface 142 may be connected (e.g., as shown in FIG. 1). The connected first sub-reflective surface 141 and the second sub-reflective surface 142 can reduce the overall length of the first reflective surface 14 to a certain extent, thereby miniaturizing the first optical element 1. In other embodiments, the first sub-reflective surface 141 and the second sub-reflective surface 142 may also be spaced apart (e.g., as shown in FIG. 14 and FIG. 15) to allow for a transition between the first sub-reflective surface 141 and the second sub-reflective surface 142, preventing the small included angle at the junction of the first sub-reflective surface 141 and the second sub-reflective surface 142 from colliding with surrounding mounting components during vehicle movement vibrations. In some embodiments, the first optical element 1 may include multiple first sub-reflective surfaces 141 and / or multiple second sub-reflective surfaces 142 (e.g., as shown in FIG. 16 and FIG. 17).

[0054] In some embodiments, an obtuse angle is preferably formed between the first sub-reflective surface 141 and the second sub-reflective surface 142. If the angle between the first sub-reflective surface 141 and the second sub-reflective surface 142 is greater than 180 degrees, the sub-reflective surface closer to the light-incident portion 11 will block light from illuminating the sub-reflective surface farther from the light-incident portion 11. Therefore, designing the angle between the first sub-reflective surface 141 and the second sub-reflective surface 142 as an obtuse angle can effectively prevent light blocking between the sub-reflective surfaces. Specifically, the second sub-reflective surface 142 can be located between the first sub-reflective surface 141 and the first light-emitting surface 12 (as shown in FIG. 1), or the first sub-reflective surface 141 can be located between the second sub-reflective surface 142 and the first light-emitting surface 12 (for example, as shown in FIG. 12 and FIG. 13).

[0055] Since the first reflecting surface 14 is located between the first light-emitting surface 12 and the light-incident portion 11, and an obtuse angle is formed between the first sub-reflecting surface 141 and the second sub-reflecting surface 142, the angle between the sub-reflecting surface closer to the first light-emitting surface 12 and the light incident on the corresponding sub-reflecting surface is closer to 90 degrees, making refraction more likely. Therefore, preferably, a reflective coating can be provided on the sub-reflecting surface closer to the first light-emitting surface 12 in the first sub-reflecting surface 141 and the second sub-reflecting surface 142 to improve the reflectivity of the light on the corresponding sub-reflecting surface and prevent the incident light from being refracted on it. The reflective coating can be an aluminum-plated coating, etc., and is not specifically limited.

[0056] In one embodiment of this application, light rays incident on the first optical element 1 via the light-incident section 11 are reflected by the second sub-reflecting surface 142 and then reflected at least once more to form light rays partially projected onto the second light-emitting surface 13; light rays incident on the first optical element 1 via the light-incident section 11 are reflected by the first sub-reflecting surface 141 and then directly form light rays projected onto the first light-emitting surface 12. Since multiple reflections will cause light efficiency loss, in this embodiment, the light-emitting surface (i.e., the first light-emitting surface 12) that reflects only once has higher brightness, thereby enabling a clear distinction between the first and second lighting effects and achieving diverse lighting effects. Of course, in other embodiments, the light rays incident on the first optical element 1 via the light-incident section 11 may be reflected by the first sub-reflecting surface 141 and then reflected at least once more to form light rays partially projected onto the first light-emitting surface 12. The light rays incident on the first optical element 1 via the light-incident section 11 may be reflected by the second sub-reflecting surface 142 and then directly form light rays projected onto the second light-emitting surface 13. Alternatively, the light rays incident on the first optical element 1 via the light-incident section 11 may be reflected by the first sub-reflecting surface 141 and the second sub-reflecting surface 142 respectively, and then reflected at least once more to form light rays projected onto the first light-emitting surface 12 and onto the second light-emitting surface 13. The difference lies in the number of reflections and the resulting light efficiency loss, thus creating a distinction between light and dark.

[0057] Alternatively, in other embodiments of this application, a reflective coating may be provided on all reflective surfaces (including the first sidewall 15 and the second sidewall 16 described below) through which the light emitted from the second light-emitting surface 13 passes in the first optical element 1 (or in some other embodiments, only some reflective surfaces (including the first sidewall 15 and the second sidewall 16 described below) may be provided with a reflective coating), thereby improving the brightness of the second lighting effect, improving the consistency of brightness with the first lighting effect, and improving aesthetics.

[0058] In this design, the first reflecting surface 14 and the second light-emitting surface 13 can be located on the same side of the first optical element 1 (e.g., as shown in Figure 1), or they can be located on opposite sides of the first optical element 1 (e.g., as shown in Figure 3). Therefore, the relative positional relationship between the second light-emitting surface 13 and the first reflecting surface 14 can be used to control the number of reflections of light incident on the second light-emitting surface 13 within the first optical element 1, thereby controlling the brightness of the emitted light from the second light-emitting surface 13. In some variations, the distance between the second light-emitting surface 13 and the first reflecting surface 14 can also be used to control the number of reflections of light incident on the second light-emitting surface 13 within the first optical element 1, thereby controlling the brightness of the emitted light from the second light-emitting surface 13. This application can implement many more variations, which will not be elaborated here.

[0059] Returning to the first optical element 1 provided in one embodiment of this application, since the angle between the first sub-reflective surface 141 and the second sub-reflective surface 142 is obtuse, if the second sub-reflective surface 142 is disposed closer to the light-incident portion 11 relative to the first sub-reflective surface 141, then some of the light rays incident on the first optical element 1 from the light-incident portion 11 may be projected onto the first sub-reflective surface 141 after being reflected by the second sub-reflective surface 142 and then after subsequent reflections. Therefore, it is preferable that the second sub-reflective surface 142 is disposed further away from the light-incident portion 11 relative to the first sub-reflective surface 141, that is, the second sub-reflective surface 142 is located between the first sub-reflective surface 141 and the first light-emitting surface 12.

[0060] Preferably, in one embodiment of this application, the first optical element 1 further includes a first sidewall 15 and / or a second sidewall 16 that are nearly parallel to the light rays projected onto the first light-emitting surface 12. The first sidewall 15 and the second sidewall 16 are disposed on opposite sides of the first optical element 1. The light rays incident on the first optical element 1 via the light-incident portion 11 are reflected by the second sub-reflecting surface 142 and then reflected again by the first sidewall 15 and / or the second sidewall 16 to form a portion of the light rays projected onto the second light-emitting surface 13. Specifically, the term "nearly parallel" in this application can mean that the angle between the light rays projected onto the first light-emitting surface 12 and the first sidewall 15 and / or the second sidewall 16 is less than 5 degrees.

[0061] Preferably, the light-incident section 11 has a focusing structure, which is used to focus light and control the angle of the light after it enters the first optical element 1 through the light-incident section 11. The focusing structure preferably has a collimation effect.

[0062] In another embodiment of the first optical element 1 provided in this application, as shown in Figures 5 to 7, the first sub-reflecting surface 141 and the second sub-reflecting surface 142 are connected, and the first sub-reflecting surface 141 and the second sub-reflecting surface 142 are located in the same base plane (the base plane can be a plane, ellipsoid, parabola, quasi-ellipsoid, quasi-parabola, or freeform surface). In this case, the incident angles of the light rays that need to illuminate the first reflecting surface 14 are different, that is, the light rays illuminating the first reflecting surface 14 are non-parallel. Thus, after being reflected by the first reflecting surface 14, the light rays will be directed in different directions, so that some light rays can be emitted from the first light-emitting surface 12 and some light rays can be emitted from the second light-emitting surface 13. At this time, the light-incident part 11 can also have a focusing structure, but the focusing structure may no longer have a collimating effect.

[0063] In another embodiment of the first optical element 1 provided in this application, as shown in Figures 8 and 9, light rays incident on the first optical element 1 via the light-incident portion 11 are reflected by the first sub-reflecting surface 141 and then undergo at least one more reflection to form light rays partially projected onto the first light-emitting surface 12; light rays incident on the first optical element 1 via the light-incident portion 11 are reflected by the second sub-reflecting surface 142 and then directly form light rays projected onto the second light-emitting surface 13. In this case, unlike the first optical element 1 provided in the aforementioned embodiment of this application, since the light rays emitted from the first light-emitting surface 12 undergo multiple reflections within the first optical element 1, resulting in light efficiency loss, the brightness of the first lighting effect is lower than that of the second lighting effect. Alternatively, in other embodiments of this application, a reflective coating may be provided on all reflective surfaces (including the first sidewall 15 and the second sidewall 16) through which the light emitted from the first light-emitting surface 12 passes in the first optical element 1 (or in some other embodiments, only some reflective surfaces (including the first sidewall 15 and the second sidewall 16) may be provided with a reflective coating), thereby improving the brightness of the first lighting effect, improving the consistency of brightness with the second lighting effect, and improving aesthetics.

[0064] In another embodiment of this application, in the first optical element 1, to avoid mutual interference between the light reflected from the sub-reflecting surfaces, it is preferable that the first sub-reflecting surface 141 is disposed further away from the light-incident portion 11 than the second sub-reflecting surface 142, that is, the first sub-reflecting surface 141 is located between the second sub-reflecting surface 142 and the first light-emitting surface 12. Another embodiment of this application also provides a first sidewall 15 and / or a second sidewall 16 that are nearly parallel to the light projected onto the second light-emitting surface 13. The first sidewall 15 and the second sidewall 16 are disposed on opposite sides of the first optical element 1. The light incident on the first optical element 1 via the light-incident portion 11 is reflected by the first sub-reflecting surface 141 and then by the first sidewall 15 and / or the second sidewall 16 to form a portion of the light projected onto the first light-emitting surface 12. Specifically, "nearly parallel" in this application can mean that the angle between the light projected onto the second light-emitting surface 13 and the first sidewall 15 and / or the second sidewall 16 is less than 5 degrees.

[0065] In some embodiments of this application, at least partially, one or more surfaces of the light-incident portion 11, the first reflecting surface 14, the first sidewall surface 15, the second sidewall surface 16, the first light-emitting surface 12, and the second light-emitting surface 13 of the first optical element 1 are provided with patterns to homogenize the light. Further, in some embodiments, patterns may be provided only on one of the light-emitting surfaces 12 and 13 to reduce the brightness difference between them. For example, in the embodiment shown in FIG. 3, since the brightness of the first light-emitting surface 12 is greater than that of the second light-emitting surface 13, patterns may be provided only on the first light-emitting surface 12. As another example, in some of the aforementioned embodiments where the brightness of the second light-emitting surface 13 is greater than that of the first light-emitting surface 12 (e.g., the embodiments shown in FIG. 8 and 9), patterns may be provided only on the second light-emitting surface 13. This application can be configured as needed, and will not be elaborated upon here.

[0066] A second aspect of this application provides a vehicle lighting fixture. Referring to Figures 1 to 17, one embodiment of the vehicle lighting fixture provided by this application includes a light source 3, a first optical element 1 as provided in any of the above embodiments, and a second optical element 2. The second optical element 2 is provided with an optical pattern 21. Light emitted from the second light-emitting surface 13 of the first optical element 1 illuminates the optical pattern 21 on the second optical element 2 to form a suspended illumination area. In this embodiment, the second illumination effect is a suspended illumination effect.

[0067] The vehicle lamp provided in this application illuminates the optical pattern 21 on the second optical element 2 through the second light-emitting surface 13 of the first optical element 1, so as to form a floating illumination area on the second optical element 2. When viewed from outside the second optical element 2, the floating illumination area appears to emit light directly at the area of ​​the optical pattern 21 of the second optical element 2, thereby achieving a special floating illumination effect.

[0068] Among them, the optical pattern 21 can be set to various patterns according to preference, such as fisheye pattern, etc.

[0069] The vehicle lighting fixtures provided in this application can be headlights, taillights, or ambient lights installed outside the vehicle; or interior lighting fixtures or ambient lights installed inside the vehicle. Specifically, when the vehicle lighting fixtures are headlights or taillights, the first illumination effect and the second illumination effect can be adjusted according to the requirements of light distribution regulations.

[0070] Therefore, compared with the relatively simple strip lighting pattern (i.e., the first lighting effect) of the existing thick-walled light guide technology, the vehicle lamp provided by this application can create an additional light and shadow clone lighting area (i.e., the second lighting effect) for the first optical element 1, and it has a floating lighting effect, making the vehicle lamp effect richer; and the vehicle lamp provided by this application can freely customize the pattern formed by the optical pattern 21 on the second optical element 2, making the shape design more free.

[0071] Furthermore, the vehicle lighting provided in the second aspect of this application includes the first optical element 1 provided in the first aspect of this application, and therefore possesses all its beneficial effects, which will not be elaborated here.

[0072] The specific structure of a vehicle lamp provided in one embodiment of this application will be further described below.

[0073] The optical pattern 21 can be disposed on the side of the second optical element 2 facing the first optical element 1. The optical pattern 21 can be formed by the surface portion of the second optical element 2 being concave (as shown in Figure 1), or by the surface portion of the second optical element 2 being convex (as shown in Figure 4), or by a combination of the two: the surface portion of the second optical element 2 being concave and the surface portion being convex.

[0074] The second optical element 2 can be an optical element manufactured by CNC machining or by injection molding, etc.; this application does not limit the processing technology of the second optical element 2. Preferably, when the second optical element 2 is manufactured by CNC machining, the optical pattern 21 formed by concavity is preferred, and when the second optical element 2 is manufactured by injection molding, the optical pattern 21 formed by convexity is preferred.

[0075] The first optical element 1 can be a transparent part, such as made of plexiglass, acrylic, etc., without limitation.

[0076] Furthermore, in another embodiment of the vehicle lighting fixture provided in this application, a blocking structure 4 may also be included. In some embodiments, the blocking structure 4 may only block the light source 3 and the light-incident portion of the first optical element 1. In some variations, the blocking structure 4 may also be used to block the first light-emitting surface 12 (as shown in Figures 10 and 11, the blocking structure 4 is used to block the first light-emitting surface 12). This can hide the first lighting effect and only display the second lighting effect, that is, only display the floating effect. In this case, it is preferable that: the light incident on the first optical element 1 via the light-incident portion 11 is reflected by the first sub-reflecting surface 141 and then undergoes at least one more reflection to form light partially projected onto the first light-emitting surface 12; the light incident on the first optical element 1 via the light-incident portion 11 is reflected by the second sub-reflecting surface 142 and then directly forms light projected onto the second light-emitting surface 13. In this way, the brightness of the second lighting effect will be brighter than the brightness of the first lighting effect, thereby improving the utilization rate of the light source 3 (the first lighting effect will be hidden, and the difference in brightness is indistinguishable from the observer's perspective). This application can achieve many more variations, which will not be elaborated here.

[0077] The third aspect of this application provides a vehicle that includes the vehicle lights provided in the second aspect of this application, and therefore possesses all the beneficial effects thereof, which will not be elaborated here.

[0078] 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.
