Technical Field
[0001] The present application relates to the technical field of vehicle lamp equipment, and in particular to a light-emitting structure, a vehicle lamp and a vehicle. Background Art
[0002] In related art, see Figure 1 The light-emitting structure 10' usually includes a light-emitting lamp 11', a reflective bowl 12', a baffle 13' and a lens 14'. The light emitted by the light-emitting lamp 11' is reflected by the reflective bowl 12' and converges at the near-field focus. Among them, the baffle 13' is set at the near-field focus, a small part of the light is blocked by the baffle 13', and most of the light passes through the baffle 13' and then shines on the road surface or wall through the lens 14'. However, the size of this light-emitting structure 10' in the light-emitting direction is relatively large. For example, the distance h1' from the light-emitting lamp 11' to the lens 14' is usually about 80 mm, which is not conducive to the miniaturization of automotive lamps. Summary of the Invention
[0003] The present application provides a light-emitting structure, a vehicle lamp and a vehicle, which are used to improve the problem in the related art that the light-emitting structure is large in the light-emitting direction, which is not conducive to the miniaturization development of automobile lamps.
[0004] In a first aspect, a light-emitting structure is provided. The light-emitting structure is used in a low-beam light-emitting module or a high-beam light-emitting module. The light-emitting structure includes:
[0005] Light-emitting parts, including light-emitting lamps;
[0006] a first reflecting bowl, located on the light-emitting side of the light-emitting lamp, for receiving and reflecting the light emitted by the light-emitting lamp; and
[0007] a second reflective bowl, located on the light-emitting side of the first reflective bowl, for receiving the light output by the first reflective bowl and reflecting it so that the light is projected into a light shape;
[0008] The optical axis of the second reflective bowl is arranged at an angle to the optical axis of the first reflective bowl.
[0009] The light-emitting structure of the present application includes a light-emitting component, a first reflective bowl and a second reflective bowl. The light-emitting lamp is used to emit light, the first reflective bowl is used to collect light, and the second reflective bowl is used to reflect the light collected by the first reflective bowl to the far field to produce the light shape required by the design. Compared with the related art, the embodiment of the present application omits the lens, and the optical axis of the second reflective bowl is set at an angle to the optical axis of the first reflective bowl, so that at least part of the first reflective bowl and at least part of the second reflective bowl overlap in the light-emitting direction, which is beneficial to reducing the size of the light-emitting structure in the light-emitting direction and is conducive to the miniaturization of car lights.
[0010] For example, the light-emitting structure emits light in the horizontal direction, and the optical axis of the second reflective bowl is set at an angle to the optical axis of the first reflective bowl, so that at least part of the first reflective bowl and at least part of the second reflective bowl are at the same horizontal position, reducing the horizontal size of the light-emitting structure.
[0011] If the light-emitting structure is used in a car lamp, only the second reflector bowl needs to correspond to the light-emitting surface of the car lamp, while the first reflector bowl and the light-emitting component can be blocked. In this way, only the second reflector bowl needs to be adapted to the light-emitting surface of the car lamp, which is suitable for applications with a narrow light-emitting surface. For example, the height of the second reflector bowl perpendicular to the light-emitting direction in the embodiment of the present application can be approximately 10 mm, which is suitable for applications with a narrow light-emitting surface.
[0012] In combination with the first aspect, in some possible implementations, the angle between the optical axis of the second reflective bowl and the optical axis of the first reflective bowl is α, and the light-emitting structure satisfies: 30°≤α≤120°.
[0013] Based on the above implementation method, the angle α between the optical axis of the second reflective bowl and the optical axis of the first reflective bowl is limited to 30°-120°, which can not only compress the size of the light-emitting structure in the light-emitting direction, but also ensure the collection efficiency of the second reflective bowl on the light output by the first reflective bowl.
[0014] In combination with the first aspect and the above implementations, in some possible implementations, α=90°.
[0015] Based on the above implementation, the size of the light-emitting structure in the light-emitting direction and the light-collecting efficiency of the second reflective bowl can be further optimized.
[0016] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the first reflection bowl has a first reflection surface facing the light-emitting lamp, the first reflection surface has a first boundary adjacent to the light-emitting lamp, and the light reflected by the first boundary is reflected by the second reflection bowl to form a cutoff line of the light shape.
[0017] Based on the above implementation, the cutoff line of the light shape is used to separate the bright and dark areas to meet regulatory requirements.

[0019] Based on the above implementation method, the prepared reflective bowl can be cut to form a first reflective bowl, and the entire concave surface of the prepared reflective bowl can be a reflective surface. In this way, after the preset reflective bowl is cut, the remaining part of the entire concave surface after cutting also has a reflective function and can serve as the first reflective surface of the first reflective bowl; or, after the prepared reflective bowl is cut, the concave surface is coated with a reflective film to form the first reflective surface.
[0020] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the first reflective bowl has a first surface facing the light-emitting lamp, the first surface includes a first reflective surface and a first non-reflective surface, and the first boundary is the boundary between the first reflective surface and the first non-reflective surface.
[0021] Based on the above implementation, the first reflective surface can be formed by coating a partial area of the first surface of the first reflective bowl with a reflective film, while the area of the first surface not coated with the reflective surface forms the first non-reflective surface without cutting.
[0022] In combination with the first aspect and the above implementations, in some possible implementations, the angle between the output light axis of the light-emitting lamp and the optical axis of the first reflective bowl is β, and the light-emitting structure satisfies: 0°<β≤30°.
[0023] Based on the above implementation method, the angle between the optical axis of the first reflective bowl and the output optical axis of the light-emitting lamp is limited to 0-30°, which can further improve the light collection efficiency of the first reflective bowl, and can make the structure of the light-emitting lamp and the first reflective bowl more compact in the light-emitting direction, and compress the size of the light-emitting structure in the light-emitting direction.

In addition, in the description of the embodiments of this application, "multiple" means two or more than two.
[0081] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.
[0082] In related art, see Figure 1 The light-emitting structure 10' usually includes a light-emitting lamp 11', a reflective bowl 12', a baffle 13' and a lens 14'. The light emitted by the light-emitting lamp 11' is reflected by the reflective bowl 12' and converges at the near-field focus. Among them, the baffle 13' is set at the near-field focus, a small part of the light is blocked by the baffle 13', and most of the light passes through the baffle 13' and then shines on the road surface or wall through the lens 14'. However, the size of this light-emitting structure 10' in the light-emitting direction is relatively large. For example, the distance h1' from the light-emitting lamp 11' to the lens 14' is usually about 80 mm, which is not conducive to the miniaturization of automotive lamps.
[0083] Example 1
[0084] See Figure 2 and Figure 3 An embodiment of the present application provides a light-emitting structure 10 , which is used in a low-beam light-emitting module. The light-emitting structure 10 includes a light-emitting element 11 , a first reflective bowl 12 , and a second reflective bowl 13 .
[0085] The light-emitting element 11 includes a light-emitting lamp 111. A first reflector bowl 12 is located on the light-emitting side of the light-emitting lamp 111 and is used to receive and reflect the light emitted by the light-emitting lamp 111. A second reflector bowl 13 is located on the light-emitting side of the first reflector bowl 12 and is used to receive and reflect the light output by the first reflector bowl 12, thereby projecting the light into a light shape. The optical axis n of the second reflector bowl 13 is arranged at an angle to the optical axis m of the first reflector bowl 12.
[0086] The light-emitting structure 10 of the embodiment of the present application includes a light-emitting element 11, a first reflective bowl 12 and a second reflective bowl 13. The light-emitting lamp 111 is used to emit light, the first reflective bowl 12 is used to collect light, and the second reflective bowl 13 is used to reflect the light collected by the first reflective bowl 12 to the far field to produce the light shape required by the design. Compared with the related art, the embodiment of the present application omits the lens, and the optical axis n of the second reflective bowl 13 is set at an angle to the optical axis m of the first reflective bowl 12, so that at least part of the first reflective bowl 12 and at least part of the second reflective bowl 13 overlap in the light-emitting direction, which is beneficial to reducing the size h1 of the light-emitting structure 10 in the light-emitting direction and facilitating the miniaturization of the car lamp 2.
[0087] For example, Figure 2 and Figure 3 The light-emitting structure 10 shown emits light in the horizontal direction, and the optical axis n of the second reflective bowl 13 is set at an angle to the optical axis m of the first reflective bowl 12, so that at least part of the first reflective bowl 12 and at least part of the second reflective bowl 13 are at the same horizontal position, reducing the horizontal size of the light-emitting structure 10.
[0088] If the light-emitting structure 10 is used in a headlight 2, only the second reflector 13 needs to correspond to the light-emitting surface of the headlight 2, while the first reflector 12 and the light-emitting element 11 can be shielded. In this way, only the second reflector 13 needs to fit the light-emitting surface of the headlight 2, making it suitable for applications with a narrow light-emitting surface. For example, the height of the second reflector 13 perpendicular to the light-emitting direction in the embodiment of the present application can be approximately 10 mm, making it suitable for applications with a narrow light-emitting surface.
[0089] Next, see Figure 2 and Figure 3 , the light-emitting component 11 is described in detail.
[0090] The light emitting lamp 111 may be an LED lamp, which has the advantages of energy saving, high efficiency, long service life, and miniaturization.
[0091] The light 111 may be a monochromatic LED lamp. Monochromatic LED lamps can emit light of a single color, with high color consistency, stable light efficiency, uniform brightness, and low power consumption. The light 111 may be a multicolor LED lamp. Multicolor LED lamps can meet the demand for color diversity. The multicolor LED lamp may be a bicolor LED lamp or a tricolor LED lamp.
[0092] The light emitting element 11 further includes a circuit board 112. The light emitting lamp 111 is mounted on the circuit board 112 and is electrically connected to the circuit board 112. The circuit board 112 is used to carry the light emitting lamp 111 and provide electrical signals to the light emitting lamp 111.
[0093] Next, see Figures 2 to 6 , the first reflection bowl 12 is described in detail.
[0094] The first reflective bowl 12 has a deflection and focusing function, which is beneficial for narrowing the light beam emitted by the light emitting lamp 111 and reducing the diffusion angle.
[0095] The angle β between the optical axis m of the first reflector 12 and the optical axis t of the light-emitting lamp 111 is such that the light-emitting structure 10 satisfies the following conditions: 0° < β < 90°. In other words, the angle β between the optical axis m of the first reflector 12 and the optical axis t of the light-emitting lamp 111 is acute, which helps the first reflector 12 collect more of the light beam emitted by the light-emitting lamp 111, thereby increasing the light collection efficiency of the first reflector 12.
[0096] In some embodiments, the light-emitting structure 10 satisfies the following conditions: 0° < β ≤ 30°. Limiting the angle β between the optical axis m of the first reflector bowl 12 and the optical axis t of the light-emitting lamp 111 to 0-30° further improves the light collection efficiency of the first reflector bowl 12, achieves a more compact structure of the light-emitting lamp 111 and the first reflector bowl 12 in the light-emitting direction, and reduces the size of the light-emitting structure 10 in the light-emitting direction.
[0097] In the direction perpendicular to the light emitting direction of the light emitting structure 10, the first reflective bowl 12 is approximately located between the light emitting lamp 111 and the second reflective bowl 13. In this way, the direction perpendicular to the light emitting direction of the light emitting structure 10, in which the light is transmitted from the light emitting lamp 111 to the first reflective bowl 12, is roughly the same as the direction from the first reflective bowl 12 to the second reflective bowl 13, thus optimizing the light transmission path. For example, Figure 3 The direction in which the light emitting lamp 111 is transmitted to the first reflective bowl 12 is generally upward in a direction perpendicular to the light emitting direction of the light emitting structure 10; the direction in which the light emitting lamp 111 is transmitted to the second reflective bowl 13 is also generally upward in a direction perpendicular to the light emitting direction of the light emitting structure 10.
[0098] The light-emitting axis t of the light-emitting lamp 111 is tilted relative to the light-emitting direction of the light-emitting structure 10. For example, Figure 2 The light emitting direction of the light emitting structure 10 is shown to be along the horizontal direction, and the light axis t of the light emitting lamp 111 is along the lower right direction. In this way, the optical axis m of the first reflective bowl 12 can be roughly upward, optimizing the light transmission path.
[0099] The first reflective bowl 12 has a first reflective surface 121 facing the light emitting lamp 111 . The first reflective surface 121 has a deflection and focusing function, which is beneficial for narrowing the light beam emitted by the light emitting lamp 111 and reducing the diffusion angle.
[0100] The first reflective surface 121 has a first boundary 123 adjacent to the light emitting lamp 111. Light reflected from the first boundary 123 forms a light cutoff line after being reflected by the second reflective bowl 13. The light cutoff line is used to separate light and dark areas to meet regulatory requirements.
[0101] In the embodiment of the present application, since the optical axis n of the second reflective bowl 13 is set at an angle to the optical axis m of the first reflective bowl 12, the shape of the cut-off line is not only determined by the shape of the first boundary 123, but also needs to take the second reflective bowl 13 into consideration (for example, the position and angle of the phase plane of the second reflective bowl 13, etc.).
[0102] In some embodiments, see Figure 4 and Figure 5 , the first surface 124 of the first reflective bowl 12 facing the light-emitting lamp 111 constitutes the first reflective surface 121, and the first boundary line 123 is the edge line of the first surface 124. At this time, the prepared reflective bowl can be cut to form the first reflective bowl 12, and the entire concave surface of the prepared reflective bowl can be a reflective surface. In this way, after the preset reflective bowl is cut, the remaining part of the entire concave surface after cutting also has a reflective function and can serve as the first reflective surface 121 of the first reflective bowl 12; or, after the prepared reflective bowl is cut, a reflective film is coated on the concave surface to form the first reflective surface 121. In other embodiments, refer to Figure 6 The first surface 124 of the first reflective bowl 12, facing the light-emitting lamp 111, includes a first reflective surface 121 and a first non-reflective surface 122. The first boundary 123 is the boundary between the first reflective surface 121 and the first non-reflective surface 122. In this case, the first reflective surface 121 can be formed by coating a portion of the first surface 124 of the first reflective bowl 12 with a reflective film, while the first non-reflective surface 122 can be formed in the uncoated portion of the first surface 124, without the need for cutting. It should be noted that if the first surface 124 of the first reflective bowl 12 includes the first reflective surface 121 and the first non-reflective surface 122, the first non-reflective surface 122 is closer to the light-emitting lamp 111 than the first reflective surface 121.
[0103] Next, see Figure 2 and Figure 3 , the second reflection bowl 13 is described in detail.
[0104] The optical axis n of the second reflective bowl 13 is set at an angle to the optical axis m of the first reflective bowl 12, so that at least part of the first reflective bowl 12 and at least part of the second reflective bowl 13 are aligned in the light emitting direction (for example, Figure 2 and Figure 3 The overlap in the horizontal direction (shown schematically) is beneficial to reducing the size h1 of the light emitting structure 10 in the light emitting direction, which is beneficial to the miniaturization development of the vehicle lamp 2.
[0105] It should be noted that as long as the optical axis n of the second reflective bowl 13 is set at an angle to the optical axis m of the first reflective bowl 12, the size of the light-emitting structure 10 in the light-emitting direction can be compressed compared to when the optical axis of the second reflective bowl is parallel to or coincides with the optical axis of the first reflective bowl.
[0106] In some embodiments, the angle α between the optical axis n of the second reflector 13 and the optical axis m of the first reflector 12 is such that the light-emitting structure 10 satisfies the following conditions: 30°≤α≤120°. Limiting the angle α between the optical axis n of the second reflector 13 and the optical axis m of the first reflector 12 to a range of 30°-120° can both reduce the size of the light-emitting structure 10 in the light-emitting direction and ensure the collection efficiency of the light output by the first reflector 12 by the second reflector 13.
[0107] Furthermore, the light-emitting structure 10 satisfies: α = 90°. That is, the optical axis n of the second reflector 13 is perpendicular to the optical axis m of the first reflector 12. This design can further optimize the size of the light-emitting structure 10 in the light-emitting direction and the light-collecting efficiency of the second reflector 13.
[0108] The light emitting direction of the second reflective bowl 13 is substantially along the horizontal direction.
[0109] The first reflective bowl 12 and the second reflective bowl 13 cooperate to produce different light shapes. The second reflective bowl can produce different light shapes by diffusion to meet different brightness and width requirements.
[0110] See Figure 5 and Figure 6 , the first boundary line 123 of the first reflecting bowl 12 has a notch. Figure 5 or Figure 6 The structure shown in FIG. 1 is schematically shown in FIG. 2 , and the second reflective bowl 13 does not have diffusion. The light pattern formed by the light emitting structure 10 is as follows: Figure 7 As shown, at this time, the cut-off line of the light shape also has a notch. Figure 5 or Figure 6 The structure shown in FIG. 1 is shown in FIG. 2 , and the second reflective bowl 13 has a diffusion of about 5°. The light pattern formed by the light emitting structure 10 is as shown in FIG. Figure 8 As shown in FIG. 1 , at this time, the cut-off line of the light shape does not correspond to the first boundary line 123 , but has a certain diffusion.
[0111] The cut-off line of the light shape can be designed according to actual needs; for example, see Figure 9 , the cut-off line of the light shape has a small angle of inclination; for example, see Figure 10 , the cutoff line of the light shape has a right-angle step; for example, see Figure 11 , the cut-off line of the light shape has a large angle of inclination; for example, see Figure 12, the cutoff line of the light shape has a notch and the depths on both sides of the notch are different.
[0112] Next, see Figure 2 and Figure 3 , the light emitting structure 10 is further described.
[0113] The light-emitting structure 10 also includes a heat sink 14, which is located on the side of the circuit board 112 facing away from the light-emitting lamp 111 and is in contact with the circuit board 112. The light-emitting element 11 generates heat during operation, and the provision of the heat sink 14 can accelerate the heat dissipation of the light-emitting element 11, thereby ensuring the operating performance and service life of the light-emitting element 11.
[0114] In summary, the light-emitting structure 10 of the embodiment of the present application includes a light-emitting component 11, a first reflective bowl 12, a second reflective bowl 13 and a heat sink 14. The light-emitting component 11 includes a light-emitting lamp 111. The first reflective bowl 12 is located on the light-emitting side of the light-emitting lamp 111, and is used to receive and reflect the light emitted by the light-emitting lamp 111. The second reflective bowl 13 is located on the light-emitting side of the first reflective bowl 12, and is used to receive and reflect the light output by the first reflective bowl 12, so that the light is projected to form a light shape. The heat sink 14 is located on the side of the circuit board 112 away from the light-emitting lamp 111 and is in contact with the circuit board 112. The optical axis n of the second reflective bowl 13 is set at an angle to the optical axis m of the first reflective bowl 12.
[0115] The optical axis n of the second reflective bowl 13 is arranged at an angle to the optical axis m of the first reflective bowl 12, so that at least a portion of the first reflective bowl 12 overlaps with at least a portion of the second reflective bowl 13 in the light-emitting direction, thereby reducing the size h1 of the light-emitting structure 10 in the light-emitting direction. For example, the size h1 of the entire light-emitting structure 10 in the light-emitting direction, including the light-emitting element 11, the first reflective bowl 12, the second reflective bowl 13, and the heat sink 14, is reduced to approximately 20 mm. Compared to the light-emitting structure 10' in the related art, which includes a light-emitting lamp 11', a reflective bowl 12', a baffle 13', and a lens 14', the distance h1' between the light-emitting lamp 11' and the lens 14' is typically approximately 80 mm. This greatly reduces the size of the light-emitting structure 10 in the light-emitting direction, facilitating the miniaturization of the vehicle lamp 2.
[0116] Furthermore, since in the entire light-emitting structure 10, only the second reflective bowl 13 is required to correspond to the light-emitting surface of the headlight 2, while the first reflective bowl 12, the light-emitting element 11, the heat sink 14, etc. can be blocked, only the second reflective bowl 13 is required to adapt to the light-emitting surface of the headlight 2, and it is suitable for application scenarios with narrow light-emitting surfaces. For example, the height of the second reflective bowl 13 perpendicular to the light-emitting direction in the embodiment of the present application can be about 10 mm. Compared with the light-emitting structure 10' in the related art including the light-emitting lamp 11', the reflective bowl 12', the baffle 13' and the lens 14', the lens 14' corresponds to the light-emitting surface of the headlight, and the height of the lens 14' perpendicular to the light-emitting direction is difficult to compress while meeting the light collection efficiency and light shape. Therefore, the embodiment of the present application is extremely suitable for application scenarios with narrow light-emitting surfaces.
[0117] Second, see Figure 13 The present application also provides a vehicle lamp 2 including the aforementioned light-emitting structure 10. The light-emitting structure 10 is similar to the aforementioned embodiment. Since the vehicle lamp 2 utilizes all the technical solutions of all the aforementioned embodiments, it at least has all the beneficial effects brought about by the technical solutions of the aforementioned embodiments, and thus will not be described in detail here.
[0118] The vehicle lamp 2 further includes a lampshade 3, which is located on the light-emitting side of the second reflective bowl 13. At least a portion of the projection of the second reflective bowl 13 along the second direction is located on the lampshade 3, and the projections of the first reflective bowl 12 and the light-emitting element 11 along the second direction are located outside the lampshade 3. The second direction may be along the light-emitting direction.
[0119] That is, in the light-emitting structure 10, the second reflective bowl 13 corresponds to the light-emitting surface of the headlight 2, while the first reflective bowl 12, the light-emitting component 11, the radiator 14, etc. can be blocked. In this way, only the second reflective bowl 13 needs to adapt to the light-emitting surface of the headlight 2, which is suitable for application scenarios with narrow light-emitting surfaces.
[0120] Thirdly, embodiments of the present application further provide a vehicle including the aforementioned headlight 2. The headlight 2 includes the aforementioned light-emitting structure 10. The light-emitting structure 10 is similar to the aforementioned embodiments. Since the vehicle utilizes all of the technical solutions of all of the aforementioned embodiments, it at least possesses all of the beneficial effects brought about by the technical solutions of the aforementioned embodiments, and thus will not be further elaborated upon herein.

[0122] See Figure 14 and Figure 15The difference between this embodiment and the first embodiment is that the light-emitting element 11 includes a plurality of light-emitting lamps 111 distributed along the first direction x, and the light-emitting structure 10 includes a plurality of first reflective bowls 12 and a plurality of second reflective bowls 13 distributed along the first direction x. The light-emitting lamps 111, the first reflective bowls 12, and the second reflective bowls 13 are arranged in a one-to-one correspondence, and all the second reflective bowls 13 emit light corresponding to the same light-emitting surface extending along the first direction x.
[0123] The light emitting structure 10 is designed to include multiple light emitting lamps 111, multiple first reflective bowls 12 and multiple second reflective bowls 13, and the light emitting lamps 111, first reflective bowls 12 and second reflective bowls 13 are arranged in a one-to-one correspondence, which can achieve different light shapes that meet regulatory and performance requirements.
[0124] For example, see Figure 15 If the light emitting element 11 includes two light emitting lamps 111, the light emitting structure 10 includes two first reflection bowls 12 and two second reflection bowls 13, wherein the first reflection bowl 12 is selected Figure 5 or Figure 6 The schematic structure shows that, among the two second reflective bowls 13, one of the second reflective bowls 13 does not have diffusion, and the other second reflective bowl 13 has diffusion of about 5°. At this time, the light pattern formed by the light emitting structure 10 is as follows: Figure 15 As shown, it can be seen that Figure 15 The light shape shown is compared to Figure 7 and Figure 8 The light shapes of the light emitting lamps 111 and the first and second reflective bowls 12 and 13 may be different according to actual needs to achieve different light shapes that meet regulatory and performance requirements.
[0125] It can be understood that, for the same light-emitting surface, the greater the number of light-emitting lamps 111 , the more conducive it is to achieving a brighter overall lighting effect and reducing dark areas.
[0126] The light emitting element 11 includes at least three light emitting lamps 111 distributed at equal intervals along the first direction x. Thus, when all the light emitting lamps 111 are lit, the light distribution is more uniform, which is beneficial to improving the uniformity of the light effect of the light emitting surface.
[0127] It is understood that if the light-emitting element 11 includes at least two light-emitting lamps 111, the operating modes of the light-emitting element 11 may include: all light-emitting lamps 111 in the light-emitting element 11 are fully illuminated, some light-emitting lamps 111 in the light-emitting element 11 are illuminated, and the remaining light-emitting lamps 111 are not illuminated.
