[0001] The present invention relates to the field of lighting, and particularly to an optical component, a vehicle headlight, a vehicle, and a method for assembling a vehicle headlight. Background Art
[0002] In vehicle lighting design, the application of the concept of single-point lighting for each imaging pixel is becoming more and more widespread. Each LED can be lit individually, and different patterns can be formed by combining the lighting.
[0003] Currently, the existing technology solution is direct LED illumination. A bracket is used to sleeve each LED on the PCB to separate the light of each LED. The inventor has found that the existing technology solution has a problem of light crosstalk, making the pattern boundary unclear. Moreover, the direct LED illumination solution cannot meet the requirements of relatively complex vehicle headlight shapes and the compactness requirements of vehicle headlights.

[0007] In one or more embodiments of the optical component, the optical path of each optical unit is configured such that: a light beam is emitted from the light source member located inside the chamber towards the reflector, a part of the light beam exits from the light-emitting surface along the length direction (D) perpendicular to the height direction after being reflected by the first reflector inside the chamber, and a part of the light beam exits from the light-emitting surface along an inclined direction (D) that is neither parallel nor perpendicular to the length direction after being reflected by the first reflector inside the chamber and then being reflected by the second reflector, providing pixel points for imaging.
[0008] In one or more embodiments of the optical component, the second reflector includes a metal plate with a thickness of 0.3 mm - 0.8 mm. Each optical unit layer has a plurality of optical units arranged in a second direction, and the plurality of second reflectors corresponding to the plurality of optical units of each optical unit layer integrally form a metal plate. The plurality of light source members corresponding to the plurality of optical units of each optical unit layer are integrally integrated into a substrate.
[0009] In one or more embodiments of the optical component, the substrate is a printed circuit board, the metal plate is flat, and the flat metal plate overlaps the flat substrate and extends planarly to the light-emitting surface.
[0010] In one or more embodiments of the optical component, the first reflectors corresponding to the plurality of optical units of each optical unit layer integrally form a reflecting portion. The reflecting portion has a first connection structure at at least one end in the second direction, the metal plate has a second connection structure at at least one end in the second direction, and the first connection structure is detachably connected in a matching manner with the second connection structure; the light-emitting surface has an optical pattern area on the front side and / or, and there is a first installation and fitting area between adjacent optical pattern areas on the same optical unit layer. The installation and fitting area has a recess; there is a second installation and fitting area between adjacent first reflectors on the same optical unit layer. The second installation area has a protrusion, and the recess cooperates with the protrusion so that adjacent chambers on the same optical unit layer are isolated.
[0011] In one or more embodiments of the optical component, the first reflector is a bowl-shaped structure, and the curved surface of the bowl-shaped structure constitutes the wall surface of the chamber.
[0012] In one or more embodiments of the optical component, the plurality of optical unit layers are stacked in the height direction, and the distance between an adjacent first optical unit layer and a second optical unit layer and the distance of the light-emitting surface in the height direction are 1.5 mm - 3 mm.
[0013] A second aspect of the present invention provides a vehicle lamp, including the optical component as described in the first aspect.
[0014] The third aspect of the present invention provides a vehicle, including the vehicle lamp as described in the second aspect, wherein a plurality of optical units of the vehicle lamp extend in the vehicle length direction and the vehicle width direction, and the provided light-emitting directions include the front or rear and the sides of the vehicle.

In addition, the first reflector provides the side wall structure of the chamber from the base body to the light-emitting surface. This not only solves the problem of light crosstalk but also provides a compact vehicle lamp structure. Specifically, by setting the second reflector, compared with the structure only provided with the base body and the first reflector, the length of the non-contact part between the base body and the first reflector is reduced, thereby reducing light crosstalk. As a result, when a single LED is lit, the boundary of the lit combination pattern is clear. And because of the structure combining the second reflector and the first reflector, a single optical unit can provide multiple light-emitting directions from the light-emitting surface, that is, the direction perpendicular to the light-emitting surface, which is the front or rear direction of the vehicle as a vehicle lamp, and the direction obliquely passing through the light-emitting surface, which is the side direction of the vehicle as a vehicle lamp. This avoids the complex and poor-structured vehicle lamp structure caused by a single optical unit only providing a single light-emitting direction, and can also meet the requirements of the profile line of the vehicle shape, especially adapting to the curved shape of the vehicle. In addition, the assembly of the vehicle lamp can also be simplified. Description of the Drawings

[0070] To make the above - mentioned objects, features and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application in conjunction with the accompanying drawings.
[0071] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein, so the present application is not limited by the specific embodiments disclosed below.
[0072] As shown in the present application and the claims, unless the context clearly indicates an exception, words such as "a", "an", "one" and / or "the" are not specifically singular and may also include the plural. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of the clearly identified steps and elements, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.
[0073] In the description of the present application, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, level" and "top, bottom" are usually based on the orientation or positional relationships shown in the drawings. It is only for the convenience of describing the present application and simplifying the description. Without contrary explanations, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation on the protection scope of the present application; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.
[0074] In addition, it should be noted that using words such as "first", "second" to limit components is only for the convenience of distinguishing the corresponding components. Without additional statements, the above words have no special meanings, so it cannot be understood as a limitation on the protection scope of the present application. In addition, although the terms used in the present application are selected from well - known and commonly used terms, some terms mentioned in the specification of the present application may be selected by the applicant according to his or her judgment. Their detailed meanings are described in the relevant parts of this description. In addition, it is required to understand the present application not only through the actual terms used, but also through the meaning implied by each term.
[0075] The vehicle lamps introduced in the following embodiments take the vehicle lamps on the front face of the vehicle as an example, but are not limited thereto. For example, they can also be the vehicle lamps on the rear of the vehicle.
[0076] As Figure 1 and Figure 3 shown, the vehicle 2000 includes vehicle lamps 1000. The vehicle lamps 1000 include the optical component 100 that will be introduced in detail in the above embodiments. A plurality of optical units 1 extend in the vehicle length direction and the vehicle width direction, and the provided light output directions include the due front F or the rear of the vehicle and the due side S, so as to meet the requirements of the contour line of the front face of the vehicle.
[0077] As Figure 2 shown, the inventor found that in the comparison scheme of direct LED illumination, for the optical component 100a of the vehicle lamp 1000a, there is not only the problem of light crosstalk, and if a structure corresponding to the contour line of the vehicle is required, the direct illumination structure needs to be obliquely arranged, so the light output direction is the oblique direction M instead of the due front F and the due side S, thus affecting the light efficiency of the vehicle lamp. If it is necessary to implement a light output direction including the due front F or the rear of the vehicle and the due side S by setting a plurality of PCB boards corresponding to different light output directions, that is, one PCB corresponds to the optical component directly illuminating the due front F, and the other PCB corresponds to the optical component directly illuminating the due side S, this will make the system significantly more complex and unable to meet the requirements for the compactness of the vehicle lamp. Especially with reference to Figure 3 shown, in some embodiments, the structure of the vehicle lamp 1000 forming the contour line has a first edge 1001 and a second edge 1002. Due to the requirement of adapting to the contour line of the shape, the inclination angle A of the first edge 1001 relative to the due side reaches 70° or even larger. If the Figure 2 structure of the optical component 100a shown is adopted, and its light output direction is the oblique direction M, it will result in poor light efficiency corresponding to the due front F.
[0078] As Figures 3 to 23, in some embodiments, the optical component 100 includes: a plurality of optical unit layers 10, which are stacked in the height direction and at least include a first optical unit layer 101 on one side in the height direction and a second optical unit layer 102 on the other side in the height direction; the optical unit layer 10 has at least one optical unit 1, and the optical unit 1 includes: a light source assembly 11, including a base 110 and a light source element 111 disposed on the base 110; a light-emitting surface 12, defining the light-emitting direction of the optical unit 1 as the direction passing through the light-emitting surface 12; a reflection assembly, including a first reflector 13 and a second reflector 14, the reflection assembly, the light-emitting surface 12 and the base 110 surround to form a chamber 150, the second reflector 14 and the base 110 form the bottom surface 151 of the chamber 150, and the first reflector 13 provides the side wall 152 of the chamber 150 from the base 110 to the light-emitting surface 12; wherein, the base 110 is non-contact with the first reflector 13 and the second reflector 14 in the height direction, in the length direction, the second reflector 14 covers a part of the length of the base 110, and the first reflector 13 is in direct contact with the second reflector 14 to close the chamber, so that adjacent optical units 1 are isolated from each other.
[0079] Reference Figure 7 And Figure 8 For the structure of, the optical path provided by the optical unit 1, the optical path of each optical unit 1 is configured as: the light beam is emitted from the light source element 111 located inside the chamber 150 towards the reflector 13, a part of the light beam is reflected by the first reflector 13 inside the chamber 150 and exits from the light-emitting surface 12 along the length direction D1 perpendicular to the height direction, and a part of the light beam is reflected by the first reflector 13 inside the chamber 150 and then reflected by the second reflector 14 and exits from the light-emitting surface 12 along an inclined direction D2 that is neither parallel nor perpendicular to the length direction, so as to provide imaging pixel points. It can be understood that the length direction D1 and the inclined direction D2 can be designed according to the position of the optical unit 1 and the specific position of the orientation, so that the light-emitting direction of the optical component 100 corresponds to Figure 1 And Figure 3 The front F and the side S shown.
[0080] It can be understood that the beneficial effects of adopting the above embodiments are as follows. The reflection component, the light-emitting surface 12 and the base 110 enclose to form a chamber 150. The second reflector and the base form the bottom surface of the chamber, and the second reflector 14 covers a part of the length of the base 110. In addition, the first reflector 13 provides the structure of the side wall of the chamber 150 from the base 110 to the light-emitting surface 12. This not only solves the problem of light crosstalk but also provides a compact headlight structure. Specifically, through the setting of the second reflector, compared with the structure with only the base and the first reflector, the length of the non-contact part between the base and the first reflector is reduced, thereby reducing light crosstalk. As a result, when a single LED is lit, the boundary of the lit combination pattern is clear. Moreover, due to the adoption of the combined structure of the second reflector and the first reflector, a single optical unit can provide multiple light-emitting directions from the light-emitting surface, that is, the direction perpendicular to the light-emitting surface, which is the front or rear direction of the vehicle for a headlight, and the direction obliquely passing through the light-emitting surface, which is the side direction of the vehicle for a headlight. This avoids the situation where a single optical unit can only provide a single light-emitting direction, resulting in a complex headlight structure with poor structural performance. In addition, it can also meet the requirements of the vehicle's body line, especially adapting to the curved shape of the vehicle. Additionally, the assembly of the headlight can be simplified.
[0081] The light source assembly 11, and the light source element 111 generally can be in the form of an LED, but not limited thereto. The corresponding base 110 can be a printed circuit board, that is, the multiple light source elements 111 corresponding to the multiple optical units 1 of each optical unit layer 10 are integrated onto one base 110 to form a printed circuit board assembly (PCBA, Printed Circuit Board Assembly) with multiple LEDs provided on a single printed circuit board. It can be understood that the reason for the non-contact between the base 110 and the first reflector 13 and the second reflector 14 in the height direction is, for example, when the base 110 is a printed circuit board, to avoid contact with the circuit of the board and / or to avoid affecting the reliability due to the force on the circuit of the printed circuit board.
[0082] The light-emitting surface 12, as the name implies, the light beam is output from the light-emitting surface 12 to provide the pattern of the headlight. Due to the structure of a single LED being lit in the optical component, that is, a single light source element 11 corresponds to a single light-emitting surface 12 to output a single pixel point, the light-emitting direction of the optical unit 1 is defined as the direction passing through the light-emitting surface 12. The form of the light-emitting surface 12, for example, can be a thick-walled part with optical patterns, but not limited thereto.
[0083] Reference Figure 22 And Figure 23As shown, the light-emitting surface 12 has an optical pattern area 120 on the front side and / or, and there is a first mounting and mating area 121 between adjacent optical pattern areas 120 of the same optical unit layer. The mounting and mating area 121 has a recess 1211. Each light source component 11 corresponds to an optical pattern area 120 to provide pixel points.
[0084] The structure of the first reflector 13 of the reflection assembly, for example, can be a bowl-shaped structure, which can form a reflecting bowl. The curved surface of the bowl-shaped structure constitutes the wall surface of the chamber 150. Its inner surface is usually a specially designed curved surface, which can be a parabolic curved surface or an elliptical curved surface. The main function of the reflector is to reflect, converge or diverge the light emitted by the light source to meet specific lighting or optical imaging requirements. Due to the advantages of high optical efficiency, simple manufacturing and assembly processes, etc., the reflector is widely used in automotive lighting optical design.
[0085] In some embodiments, the structure of the first reflector 13 of the optical unit layer of the same layer is as follows Figures 9 to 21 As shown, the first reflectors 13 corresponding to the multiple optical units 1 of each optical unit layer 10 integrally form a reflection part 130. The reflection part 130 has a first connection structure 1301 at at least one end in the second direction. The metal plate 140 has a second connection structure 1401 at at least one end in the second direction. The first connection structure 1301 and the second connection structure 1401 are matched and detachably connected. For example Figure 19 As shown in the snap connection structure, it is easy to assemble and the connection structure is stable. For the connection structure of adjacent optical units, there is a second mounting and mating area 131 between adjacent first reflectors 13 of the same optical unit layer. The second mounting area 131 has a protrusion 1311. The recess 1211 cooperates with the protrusion 1311 so that the adjacent chambers 150 of the same optical unit layer are isolated.
[0086] The structure of the second reflector 14 of the reflection component is different from that of the first reflector 13. The difference is that although the second reflector 14 also functions as a reflector, it is different from the first reflector 13 in that the second reflector 14 may include a metal plate 140 with a thickness of 0.3 mm - 0.8 mm, for example, it may be 0.5 mm. Each optical unit layer 10 has a plurality of optical units 1 arranged in the second direction, and the plurality of second reflectors 14 corresponding to the plurality of optical units 1 of each optical unit layer 10 are integrally formed into a metal plate 140, for example, it may be a thin steel plate. The structure using a metal plate is simple and easy to form, and generally, it is easier to form compared to the first reflector 13 using a reflector bowl. Therefore, generally, the first reflector 13 and the second reflector 14 are manufactured separately and then mechanically connected. If the first reflector 13 and the second reflector 14 are integrally formed, not only the cost is higher, but also the forming difficulty is greater.
[0087] In some embodiments, corresponding to the flat substrate 110, that is, the substrate 110 corresponding to a printed circuit board, the metal plate 140 is also flat. The flat metal plate 140 overlaps the flat substrate 110 and extends planar to the light-emitting surface 12, as Figure 18 shown, the structure of the metal plate 140 and the first reflector 13 of the same layer can also be detachably connected through the snap structure on the outside of the first reflector 13, for example Figure 18 shown by the second snap 1302 of the first reflector 13. In a single optical unit 1, the first reflector 13 and the second reflector 14 are in direct contact to enclose the chamber, and it can be a mechanical connection with close fit, such as abutting, but not limited thereto.
[0088] It can be understood that the optical component 100 with the above-described embodiments can achieve the compactness of the structure. For example, in some embodiments, for a plurality of optical unit layers 10 stacked in the height direction, the distance D between the adjacent first optical unit layer 101 and the second optical unit layer 102 in the height direction, which is the distance between the light-emitting surfaces 12 in the height direction, is 1.5 mm - 3 mm, that is, the distance between the adjacent optical pattern regions in the height direction is 1.5 mm - 3 mm, meeting the requirement of the vehicle lamp for the compactness of the optical component structure.
[0089] As introduced above, the present application also provides an assembly method for a vehicle lamp for the vehicle lamp 1000 introduced above. The assembly method includes:
[0090] S100. Assemble the light source component 11, the light-emitting surface 12, and the reflection component of the first optical unit layer 101;
[0091] S200. Assemble the light source component 11, the light-emitting surface 12, and the reflection component of the second optical unit layer 102;
[0092] S300. Stack the first optical unit layer 101 on the second optical unit layer 102.
[0093] It can be understood that the above descriptions of the first optical unit layer and the second optical unit layer only describe the stacking of adjacent optical unit layers, rather than limiting the vehicle lamp to only two layers. For example, for the five-layer structure shown in the figure, for the five-layer structure, the fifth optical unit layer 105 at the bottom layer and the fourth optical layer 104 stacked on the fifth optical layer 105 share a printed circuit board as the substrate 110, and the light source components 111 are respectively located on the upper surface and the lower surface of the substrate 110. The third optical layer 103 stacked on the fourth optical layer 104 has a structure similar to that of the above-mentioned first optical layer 101 and second optical layer 102, which will not be elaborated here. It can be understood that the number of layers of the stacked optical unit layers can also be more or less. The assembly method of the light source assembly 11, the light-emitting surface 12, and the reflection assembly of the optical unit layer 102 can be the assembly through the snap structure introduced above, and the structure of stacking the first optical unit layer 101 on the second optical unit layer 102 can be the assembly by nailing, and neither is limited thereto.
[0094] In summary, the beneficial effects of the optical component, the vehicle lamp, the vehicle, and the vehicle lamp assembly method include but are not limited to that the chamber 150 is surrounded by the reflection assembly, the light-emitting surface 12, and the substrate 110. The second reflector and the substrate form the bottom surface of the chamber, and the second reflector 14 covers a part of the length of the substrate 110, and the first reflector 13 provides the structure of the side wall of the chamber 150 from the substrate 110 to the light-emitting surface 12, which not only solves the problem of light crosstalk but also provides a compact vehicle lamp structure. Specifically, through the setting of the second reflector, compared with the structure with only the substrate and the first reflector, the non-contact length between the substrate and the first reflector is reduced, thereby reducing the light crosstalk, so that when a single LED is lit, the boundary of the lit combination pattern is clear. And because of the structure combining the second reflector and the first reflector, a single optical unit can provide multiple light-emitting directions from the light-emitting surface, that is, the direction vertically passing through the light-emitting surface, which is the front or rear direction of the vehicle as a vehicle lamp, and the direction obliquely passing through the light-emitting surface, which is the side direction of the vehicle as a vehicle lamp, thus avoiding the complexity and poor structure of the vehicle lamp structure caused by a single optical unit only being able to provide a single light-emitting direction, and can also adapt to the profile requirements of the vehicle's shape, especially to fit the curved shape of the vehicle. In addition, the assembly of the vehicle lamp can also be simplified.

Therefore, as long as the changes and modifications to the above embodiments are within the scope of the spirit of this application, they will fall within the scope of the claims of this application.
