Description

Technical Field

[0001] This application relates to the field of automotive lighting equipment technology, and in particular to a light-emitting structure, an automotive lamp, and a vehicle. Background Technology

[0002] See related technologies. Figure 1 The light-emitting structure 10' typically includes a lamp 11', a reflector 12', a baffle 13', and a lens 14'. The light emitted by the lamp 11' is reflected by the reflector 12' and converges at the near-field focal point. The baffle 13' is positioned at the near-field focal point; a small portion of the light is blocked by the baffle 13', while most of the light passes through the baffle 13' and then through the lens 14' to illuminate the road surface or wall. However, this light-emitting structure 10' has a relatively large dimension in the light-emitting direction; for example, the distance h1' between the lamp 11' and the lens 14' is typically around 80mm, which is detrimental to the miniaturization of automotive lighting. Utility Model Content

[0003] This application provides a light-emitting structure, a vehicle lamp, and a vehicle to improve the problem that the light-emitting structure in the related art has a large size in the light-emitting direction, which is not conducive to the miniaturization of automotive lamps.

[0004] Firstly, a light-emitting structure is provided, which is used in a low-beam light-emitting module or a high-beam light-emitting module, the light-emitting structure comprising:

[0005] Light-emitting components, including lamps;

[0006] A first reflector bowl, located on the light-emitting side of the light-emitting lamp, is used to receive and reflect the light emitted by the light-emitting lamp; and

[0007] The second reflector bowl is located on the light-emitting side of the first reflector bowl and is used to receive and reflect the light emitted by the first reflector bowl so that the light is projected to form a light pattern.

[0008] The optical axis of the second reflector bowl is set at an angle to the optical axis of the first reflector bowl.

[0009] The light-emitting structure of this application includes a light-emitting element, a first reflector bowl, and a second reflector bowl. The light-emitting lamp is used to emit light, the first reflector bowl is used to collect light, and the second reflector bowl is used to reflect the light collected by the first reflector bowl to the far field to generate the light pattern required by the design. Compared with related technologies, the embodiment of this application eliminates the lens, and the optical axis of the second reflector bowl is set at an angle to the optical axis of the first reflector bowl, so that at least a part of the first reflector bowl and at least a part of the second reflector bowl overlap in the light emission direction, which is beneficial to reducing the size of the light-emitting structure in the light emission direction and is conducive to the miniaturization of vehicle lights.

[0010] For example, the light-emitting structure emits light in a horizontal direction, and the optical axis of the second reflector bowl is set at an angle to the optical axis of the first reflector bowl. This can ensure that at least a part of the first reflector bowl and at least a part of the second reflector bowl are at the same horizontal position, thereby reducing the size of the light-emitting structure in the horizontal direction.

[0011] If the light-emitting structure is used in a vehicle lamp, only the second reflector needs to correspond to the light-emitting surface of the lamp, while the first reflector, light-emitting element, etc., can be blocked. In this way, only the second reflector needs to be adapted to the light-emitting surface of the lamp, which is suitable for applications with narrow light-emitting surfaces. For example, in the embodiments of this application, the height of the second reflector perpendicular to the light-emitting direction can be about 10mm, which is suitable for applications with narrow light-emitting surfaces.

[0012] In conjunction 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 reflector bowl and the optical axis of the first reflector bowl is limited to 30°-120°. This can both compress the size of the light-emitting structure in the light-emitting direction and ensure the collection efficiency of the second reflector bowl for the light output from the first reflector bowl.

[0014] Combining the first aspect and the above implementation methods, in some possible implementation methods, α = 90°.

[0015] Based on the above implementation method, it is possible to further optimize the size of the light-emitting structure in the light-emitting direction and the light-collecting efficiency of the second reflector bowl.

[0016] In combination with the first aspect and the above implementation, in some possible implementations, the first reflector bowl has a first reflective surface facing the light source, the first reflective surface has a first boundary adjacent to the light source, and the light reflected by the first boundary forms the cutoff line of the light pattern after being reflected by the second reflector bowl.

[0017] Based on the above implementation method, the cutoff line of the light shape is used to divide the bright and dark areas, which meets the regulatory requirements.

[0018] In combination with the first aspect and the above implementation, in some possible implementations, the first reflective bowl has a first surface facing the light-emitting lamp, the first surface being configured as the first reflective surface, and the first boundary being the edge line of the first surface.

[0019] Based on the above implementation method, the pre-reflective bowl can be cut to form the first reflective bowl. The entire concave surface of the pre-reflective bowl can be a reflective surface. Thus, after the pre-reflective bowl is cut, the remaining part of the entire concave surface after cutting also has a reflective function and can be used as the first reflective surface of the first reflective bowl; or, after the pre-reflective bowl is cut, a reflective film is coated on the concave surface to form the first reflective surface.

[0020] In combination with the first aspect and the above implementation, in some possible implementations, the first reflector bowl has a first surface facing the light-emitting lamp, the first surface including 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 method, a first reflective surface can be formed by coating a portion of the first surface of the first reflective bowl with a reflective film, while the portion of the first surface without a reflective film is formed as a first non-reflective surface, without the need for cutting.

[0022] Combining the first aspect and the above implementation methods, in some possible implementation methods, the angle between the emission optical 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 reflector bowl and the emission optical axis of the light-emitting lamp is limited to 0-30°, which can further improve the light collection efficiency of the first reflector bowl and make the structure of the light-emitting lamp and the first reflector bowl more compact in the light emission direction, thus compressing the size of the light-emitting structure in the light emission direction.

[0024] In combination with the first aspect and the above implementation methods, some possible implementation methods also include:

[0025] The heat sink, the light-emitting element further includes a circuit board, the light-emitting lamp is mounted on the circuit board and electrically connected to the circuit board, and the heat sink is located on the side of the circuit board away from the light-emitting lamp and is attached to the circuit board.

[0026] Based on the above implementation method, the light-emitting component will generate heat when it is working. The heat sink can accelerate the heat dissipation of the light-emitting component and meet the working performance and service life of the light-emitting component.

[0027] In combination with the first aspect and the above implementation, in some possible implementations, the light-emitting element includes a plurality of light-emitting lamps distributed along a first direction, and the light-emitting structure includes a plurality of first reflective bowls and a plurality of second reflective bowls distributed along the first direction. The light-emitting lamps, the first reflective bowls and the second reflective bowls are arranged in a one-to-one correspondence, and all the second reflective bowls emit light from the same light-emitting surface extending along the first direction.

[0028] Based on the above implementation method, the light-emitting structure is designed to include multiple light-emitting lamps, multiple first reflector bowls, and multiple second reflector bowls, with each light-emitting lamp, first reflector bowl, and second reflector bowl being set in a one-to-one correspondence, which can achieve different light patterns that meet regulatory and performance requirements.

[0029] Combining the first aspect and the above implementation methods, in some possible implementation methods, the structures of the first boundaries of at least two of the first reflective bowls are different.

[0030] Based on the above implementation method, different light patterns that meet regulatory and performance requirements can be achieved.

[0031] Combining the first aspect and the above implementation methods, in some possible implementation methods, at least two of the second reflective bowls have different structures.

[0032] Based on the above implementation method, different light patterns that meet regulatory and performance requirements can be achieved.

[0033] In combination with the first aspect and the above-described implementation, in some possible implementations, the light-emitting structure includes multiple light-emitting units, each of which includes a light-emitting lamp and a first reflector bowl and a second reflector bowl corresponding to the light-emitting lamp.

[0034] In combination with the first aspect and the above implementation, in some possible implementations, all of the plurality of light-emitting units are first light-emitting units, in which the light-emitting lamp and the corresponding first reflector are both located below the corresponding second reflector.

[0035] Based on the above implementation method, it is applicable to low beam emission modules.

[0036] In combination with the first aspect and the above implementation, in some possible implementations, all of the multiple light-emitting units are second light-emitting units, in which the light-emitting lamp and the corresponding first reflector are both located above the corresponding second reflector.

[0037] Based on the above implementation method, it is applicable to high beam emission modules.

[0038] In combination with the first aspect and the above implementation, in some possible implementations, the plurality of light-emitting units include a first light-emitting unit and a second light-emitting unit. In the first light-emitting unit, the light-emitting lamp and the corresponding first reflector are both located below the corresponding second reflector. In the second light-emitting unit, the light-emitting lamp and the corresponding first reflector are both located above the corresponding second reflector.

[0039] Based on the above implementation method, it is applicable to far- and near-beam light emission modules.

[0040] Secondly, a vehicle lamp is provided, including the aforementioned light-emitting structure.

[0041] The vehicle headlight of this application includes the light-emitting structure described above. This light-emitting structure refers to the above embodiments. Since the vehicle headlight adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above embodiments.

[0042] In conjunction with the second aspect, some possible implementations also include:

[0043] A lampshade is located on the light-emitting side of the second reflector bowl, at least a portion of the projection of the second reflector bowl along a second direction is located on the lampshade, and the projections of the first reflector bowl and the light-emitting element along the second direction are located outside the lampshade, wherein the second direction is perpendicular to the lampshade.

[0044] Based on the above implementation method, in the light-emitting structure, the second reflector bowl corresponds to the light-emitting surface of the headlight, while the first reflector bowl, light-emitting component, heat sink, etc. can be blocked. Thus, only the second reflector bowl needs to be adapted to the light-emitting surface of the headlight, which is suitable for application scenarios with narrow light-emitting surfaces.

[0045] Thirdly, a vehicle is provided, including the aforementioned headlights.

[0046] The vehicle of this application includes a headlight with a light-emitting structure, which is described in the above embodiments. Since the vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments.

[0080] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0081] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0082] See related technologies. Figure 1 The light-emitting structure 10' typically includes a lamp 11', a reflector 12', a baffle 13', and a lens 14'. The light emitted by the lamp 11' is reflected by the reflector 12' and converges at the near-field focal point. The baffle 13' is positioned at the near-field focal point; a small portion of the light is blocked by the baffle 13', while most of the light passes through the baffle 13' and then through the lens 14' to illuminate the road surface or wall. However, this light-emitting structure 10' has a relatively large dimension in the light-emitting direction; for example, the distance h1' between the lamp 11' and the lens 14' is typically around 80mm, which is detrimental to the miniaturization of automotive lighting.

[0083] Example 1

[0084] See Figure 2 and Figure 3 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 reflector 12 and a second reflector 13.

[0085] The light-emitting element 11 includes a light-emitting lamp 111. A first reflector 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 13 is located on the light-emitting side of the first reflector 12 and is used to receive and reflect the light emitted by the first reflector 12, so that the light is projected to form a light pattern. The optical axis n of the second reflector 13 is set at an angle to the optical axis m of the first reflector 12.

[0086] The light-emitting structure 10 of this application embodiment includes a light-emitting element 11, a first reflector 12 and a second reflector 13. The light-emitting lamp 111 is used to emit light, the first reflector 12 is used to collect light, and the second reflector 13 is used to reflect the light collected by the first reflector 12 to the far field to generate the light pattern required by the design. Compared with related technologies, this application embodiment omits the lens, and the optical axis n of the second reflector 13 is set at an angle to the optical axis m of the first reflector 12, so that at least a part of the first reflector 12 and at least a part of the second reflector 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 is beneficial to the miniaturization of the vehicle lamp 2.

[0087] For example, Figure 2 and Figure 3 The light-emitting structure 10 shown emits light in the horizontal direction. The optical axis n of the second reflector bowl 13 is set at an angle to the optical axis m of the first reflector bowl 12, which can make at least a part of the first reflector bowl 12 and at least a part of the second reflector bowl 13 at the same horizontal position, thereby reducing the size of the light-emitting structure 10 in the horizontal direction.

[0088] If the light-emitting structure 10 is used in the vehicle lamp 2, only the second reflector 13 needs to correspond to the light-emitting surface of the vehicle lamp 2, while the first reflector 12, the light-emitting element 11, etc., can be blocked. In this way, only the second reflector 13 needs to be adapted to the light-emitting surface of the vehicle lamp 2, which is suitable for applications with narrow light-emitting surfaces. For example, in the embodiments of this application, the height of the second reflector 13 perpendicular to the light-emitting direction can be about 10mm, which is suitable for applications with narrow light-emitting surfaces.

[0089] Next, see Figure 2 and Figure 3 The light-emitting element 11 will be described in detail.

[0090] The 111 light can be an LED light. LED lights have advantages such as energy efficiency, long lifespan, and miniaturization.

[0091] The luminaire 111 can be a single-color LED. A single-color LED emits light of a single color, offering high color consistency, stable luminous efficacy, uniform brightness, and low power consumption. The luminaire 111 can also be a multi-color LED. Multi-color LEDs can meet diverse color requirements. Specifically, the multi-color LED can be a dual-color LED or a tri-color LED.

[0092] The light-emitting element 11 also includes a circuit board 112, on which the light-emitting lamp 111 is mounted and electrically connected. 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 reflecting bowl 12 will be described in detail.

[0094] The first reflecting bowl 12 has a deflecting and focusing effect, which helps to narrow the beam emitted by the light lamp 111 and reduce the diffusion angle.

[0095] The angle between the optical axis m of the first reflector bowl 12 and the output optical axis t of the light-emitting lamp 111 is β, and the light-emitting structure 10 satisfies: 0° < β < 90°. That is, the angle β between the optical axis m of the first reflector bowl 12 and the output optical axis t of the light-emitting lamp 111 is an acute angle, which is beneficial for more of the light beam emitted by the light-emitting lamp 111 to be collected by the first reflector bowl 12, thereby increasing the light collection efficiency of the first reflector bowl 12.

[0096] In some embodiments, the light-emitting structure 10 satisfies: 0°<β≤30°. The angle β between the optical axis m of the first reflector bowl 12 and the emission optical axis t of the light-emitting lamp 111 is limited to 0-30°, which can further improve the light collection efficiency of the first reflector bowl 12 and make the structure of the light-emitting lamp 111 and the first reflector bowl 12 more compact in the light emission direction, thus compressing the size of the light-emitting structure 10 in the light emission direction.

[0097] In a direction perpendicular to the light emission direction of the light-emitting structure 10, the first reflector 12 is approximately located between the light-emitting lamp 111 and the second reflector 13. This ensures that, in a direction perpendicular to the light emission direction of the light-emitting structure 10, the direction of light transmission from the light-emitting lamp 111 to the first reflector 12 is approximately the same as the direction of light transmission from the first reflector 12 to the second reflector 13, thus optimizing the light transmission path. For example, Figure 3 The direction in which the light-emitting lamp 111 transmits light to the first reflector bowl 12 is approximately upward in a direction perpendicular to the light-emitting direction of the light-emitting structure 10; the direction in which the light-emitting bowl 12 transmits light to the second reflector bowl 13 is also approximately upward in a direction perpendicular to the light-emitting direction of the light-emitting structure 10.

[0098] The emission optical axis t of the light-emitting lamp 111 is tilted relative to the light emission direction of the light-emitting structure 10. For example, Figure 2 The light-emitting structure 10 shown has a horizontal light-emitting direction, and the light-emitting axis t of the light-emitting lamp 111 is in the lower right direction. In this way, the light axis m of the first reflector bowl 12 can be roughly upward, thus optimizing the light transmission path.

[0099] The first reflector bowl 12 has a first reflective surface 121 facing the light-emitting lamp 111. The first reflective surface 121 has a deflecting and focusing effect, which helps to narrow the light beam emitted by the light-emitting lamp 111 and reduce the diffusion angle.

[0100] The first reflective surface 121 has a first boundary 123 adjacent to the light-emitting lamp 111. The light reflected by the first boundary 123 is reflected by the second reflective bowl 13 to form a cutoff line of the light pattern. The cutoff line of the light pattern is used to separate the bright and dark areas to meet regulatory requirements.

[0101] In this embodiment, since the optical axis n of the second reflector bowl 13 is set at an angle to the optical axis m of the first reflector bowl 12, the shape of the cutoff line is not only determined by the shape of the first boundary line 123, but also needs to take into account the second reflector bowl 13 (for example, the position and angle of the phase surface of the second reflector bowl 13).

[0102] In some embodiments, see Figure 4 and Figure 5 The first reflective bowl 12, facing the light-emitting lamp 111, has a first surface 124 that forms a first reflective surface 121, and a first boundary 123 that is the edge line of the first surface 124. In this case, the pre-reflective bowl can be cut to form the first reflective bowl 12. The entire concave surface of the pre-reflective bowl can be a reflective surface. Thus, after cutting the pre-reflective bowl, the remaining portion of the entire concave surface also has a reflective function and can serve as the first reflective surface 121 of the first reflective bowl 12. Alternatively, after cutting the pre-reflective bowl, a reflective film can be deposited on the concave surface to form the first reflective surface 121. In other embodiments, see [reference needed]. Figure 6 The first surface 124 of the first reflector bowl 12 facing the light source 111 includes a first reflective surface 121 and a first non-reflective surface 122, with a first boundary 123 defining 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 depositing a reflective film on a portion of the first surface 124 of the first reflector bowl 12, while the uncoated portion of the first surface 124 forms the first non-reflective surface 122, eliminating the need for cutting. It should be noted that if the first surface 124 of the first reflector bowl 12 includes both a first reflective surface 121 and a first non-reflective surface 122, then the first non-reflective surface 122 is closer to the light source 111 than the first reflective surface 121.

[0103] Next, see Figure 2 and Figure 3 The second reflector bowl 13 will be described in detail.

[0104] The optical axis n of the second reflector bowl 13 is set at an angle to the optical axis m of the first reflector bowl 12, which can ensure that at least a portion of the first reflector bowl 12 and at least a portion of the second reflector bowl 13 are aligned in the light emission direction (e.g., Figure 2 and Figure 3 The overlap in the horizontal direction (as shown in the diagram) helps to reduce the size h1 of the light-emitting structure 10 in the light-emitting direction, which is beneficial to the miniaturization of the vehicle lamp 2.

[0105] It should be noted that as long as the optical axis n of the second reflector bowl 13 is set at an angle to the optical axis m of the first reflector bowl 12, the size of the light-emitting structure 10 in the light-emitting direction can be compressed compared to the optical axis of the second reflector bowl being parallel or coincident with the optical axis of the first reflector bowl.

[0106] In some embodiments, the angle between the optical axis n of the second reflector 13 and the optical axis m of the first reflector 12 is α, and the light-emitting structure 10 satisfies: 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 30°-120° can both compress the size of the light-emitting structure 10 in the light-emitting direction and ensure the collection efficiency of the second reflector 13 for the light output from the first reflector 12.

[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 enables further optimization of the dimensions of the light-emitting structure 10 in the light-emitting direction and the light-receiving efficiency of the second reflector 13.

[0108] The light emission direction of the second reflecting bowl 13 is roughly horizontal.

[0109] The first reflector 12 and the second reflector 13 work together to produce different light patterns. The second reflector can produce different light patterns through diffusion to meet different brightness and width requirements.

[0110] See Figure 5 and Figure 6 The first boundary 123 of the first reflecting bowl 12 has a notch. If the first reflecting bowl 12 is selected... Figure 5 or Figure 6 The schematic structure shows that the second reflective bowl 13 does not diffuse, and the light pattern formed by the light-emitting structure 10 is as follows. Figure 7 This indicates that the cutoff line of the light pattern also has a notch. If the first reflecting bowl 12 is selected... Figure 5 or Figure 6 The schematic structure shows that the second reflective bowl 13 has a diffusion of about 5°, and the light pattern formed by the light-emitting structure 10 is as follows. Figure 8 This indicates that at this point, the cutoff line of the light pattern does not correspond to the first boundary line 123, but there is a certain degree of diffusion.

[0111] The cutoff line of the beam can be designed according to actual needs; for example, see [reference needed]. Figure 9 The cutoff line of the light pattern has a small angle of inclination; for example, see [reference needed]. Figure 10 The cutoff line of the light shape has a right-angled step; for example, see [reference needed]. Figure 11 The cutoff line of the light pattern has a large angle of inclination; for example, see [reference needed]. Figure 12The cutoff line of the light shape has a notch with different depths on both sides of the notch.

[0112] Next, see Figure 2 and Figure 3 Further explanation of the light-emitting structure 10 is provided.

[0113] The light-emitting structure 10 also includes a heat sink 14, which is located on the side of the circuit board 112 away from the light lamp 111 and is attached to the circuit board 112. When the light-emitting element 11 is working, it will generate heat. The heat sink 14 can accelerate the heat dissipation of the light-emitting element 11, thus meeting the working performance and service life requirements of the light-emitting element 11.

[0114] In summary, the light-emitting structure 10 of this embodiment includes a light-emitting element 11, a first reflector 12, a second reflector 13, and a heat sink 14. The light-emitting element 11 includes a light-emitting lamp 111. The first reflector 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 reflector 13 is located on the light-emitting side of the first reflector 12 and is used to receive and reflect the light output by the first reflector 12, so that the light is projected to form a light pattern. The heat sink 14 is located on the side of the circuit board 112 away from the light-emitting lamp 111 and is attached to the circuit board 112. The optical axis n of the second reflector 13 is set at an angle to the optical axis m of the first reflector 12.

[0115] In this design, the optical axis n of the second reflector 13 is set at an angle to the optical axis m of the first reflector 12, which allows at least a portion of the first reflector 12 and at least a portion of the second reflector 13 to overlap in the light-emitting direction. This helps to reduce 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, including the light-emitting element 11, the first reflector 12, the second reflector 13, and the heat sink 14, in the light-emitting direction is reduced to approximately 20 mm. Compared to the light-emitting structure 10' in related technologies, which includes a light-emitting lamp 11', a reflector 12', a baffle 13', and a lens 14', the distance h1' between the light-emitting lamp 11' and the lens 14' is typically around 80 mm. This significantly reduces the size of the light-emitting structure 10 in the light-emitting direction, which is beneficial for the miniaturization of the vehicle lamp 2.

[0116] Furthermore, since only the second reflector 13 in the entire light-emitting structure 10 corresponds to the light-emitting surface of the headlight 2, while the first reflector 12, the light-emitting element 11, the heat sink 14, etc., can be blocked, only the second reflector 13 needs to be adapted to the light-emitting surface of the headlight 2, which is suitable for applications with narrow light-emitting surfaces. For example, in this embodiment, the height of the second reflector 13 perpendicular to the light-emitting direction can be about 10mm. Compared with the related technology's light-emitting structure 10', which includes a light-emitting lamp 11', a reflector 12', a baffle 13', and a lens 14', where 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 satisfying light collection efficiency and light shape, this embodiment is extremely suitable for applications with narrow light-emitting surfaces.

[0117] Secondly, see Figure 13 This application also provides a vehicle lamp 2, including the light-emitting structure 10 described above. The light-emitting structure 10 refers to the above embodiments. Since the vehicle lamp 2 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.

[0118] The headlight 2 also includes a lampshade 3, which is located on the light-emitting side of the second reflector 13. At least a portion of the projection of the second reflector 13 along a second direction is located on the lampshade 3. The projections of the first reflector 12 and the light-emitting element 11 along the second direction are located outside the lampshade 3, wherein the second direction is perpendicular to the lampshade 3. The second direction can be along the light-emitting direction.

[0119] That is, in the light-emitting structure 10, the second reflector bowl 13 corresponds to the light-emitting surface of the headlight 2, while the first reflector bowl 12, the light-emitting element 11, the heat sink 14, etc. can be blocked. Thus, only the second reflector bowl 13 needs to be adapted to the light-emitting surface of the headlight 2, which is suitable for application scenarios with narrow light-emitting surfaces.

[0120] Thirdly, this application also provides a vehicle including the aforementioned headlight 2. The headlight 2 includes the aforementioned light-emitting structure 10. The light-emitting structure 10 refers to the aforementioned embodiments. Since the vehicle adopts all the technical solutions of all the aforementioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the aforementioned embodiments, which will not be described in detail here.

[0121] Example 2

[0122] See Figure 14 and Figure 15The difference between this embodiment and Embodiment 1 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 from the same light-emitting surface extending along the first direction x.

[0123] The light-emitting structure 10 includes multiple light-emitting lamps 111, multiple first reflector bowls 12, and multiple second reflector bowls 13, and the light-emitting lamps 111, first reflector bowls 12, and second reflector bowls 13 are arranged in a one-to-one correspondence, which can realize different light patterns that meet regulatory and performance requirements.

[0124] For example, see Figure 15 If the light-emitting element 11 includes two light-emitting lamps 111, and the light-emitting structure 10 includes two first reflective bowls 12 and two second reflective bowls 13, wherein the first reflective bowls 12 are selected from... Figure 5 or Figure 6 In the schematic structure, of the two second reflective bowls 13, one second reflective bowl 13 has no diffusion, while the other second reflective bowl 13 has diffusion at approximately 5°. In this case, 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 patterns have certain differences. That is, multiple sets of light lamps 111, first reflector bowl 12 and second reflector bowl 13 can be combined according to actual needs to achieve different light patterns that meet regulatory and performance requirements.

[0125] Understandably, for the same light-emitting surface, the more light-emitting lamps there are, the better it is to achieve a brighter overall lighting effect and reduce dark areas.

[0126] The light-emitting element 11 includes at least three light-emitting lamps 111 that are equally spaced along the first direction x. In this way, 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 output surface.

[0127] It is understood that if the light-emitting element 11 includes at least two light-emitting lamps 111, the working mode of the light-emitting element 11 may include: all light-emitting lamps 111 in the light-emitting element 11 are lit, or some light-emitting lamps 111 in the light-emitting element 11 are lit while the remaining light-emitting lamps 111 are not lit.

In other embodiments, at least two of the plurality of first reflective bowls 12 may have different structures. If at least two of the plurality of first reflective bowls 12 have different structures, this can be because the structures of the first boundary lines 123 of the at least two first reflective bowls 12 are different.

[0131] In some embodiments, the plurality of first reflector bowls 12 can be independent of each other. In this case, when the light-emitting structure 10 is used for the vehicle lamp 2, each first reflector bowl 12 can be connected and fixed to the structural components of the vehicle lamp 2 respectively. In other embodiments, the plurality of first reflector bowls 12 are connected as a whole. In this case, when the light-emitting structure 10 is used for the vehicle lamp 2, it can be connected and fixed to the structural components of the vehicle lamp 2 together, reducing assembly steps.

In other embodiments, at least two of the plurality of second reflective bowls 13 may have different structures. If at least two of the plurality of second reflective bowls 13 have different structures, this can be because at least two of the second reflective bowls 13 have different diffusion degrees.

[0136] In the light-emitting structure 10, all light-emitting units are first light-emitting units. In each first light-emitting unit, the light-emitting lamp 111 and the corresponding first reflector 12 are located below the corresponding second reflector 13. This light-emitting structure 10 is suitable for use in low beam light-emitting modules.

This light-emitting structure 10 is suitable for high beam light-emitting modules.
