[0032] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0033] The following is for reference. Figures 1-4 A vehicle lighting assembly 100 according to an embodiment of this application is described.

[0034] According to an embodiment of this application, a vehicle lighting assembly 100 includes: a first light guide plate 1 and a light-emitting unit 2. At least a portion of the first light guide plate 1 extends along the direction of a first plane. A light-inlet end face 11 is formed on one side edge of the first plane. A light-emitting surface 12 and a reflective surface 13 are formed on both sides of the first light guide plate 1 in the thickness direction, respectively. The light-emitting unit 2 is provided with a light-emitting element 21. The light-emitting unit 2 is disposed on one side edge of the first light guide plate 1, and the light-emitting element 21 emits light toward the light-inlet end face 11.

[0035] In related technologies, existing vehicle signal lights mainly adopt a two-way light-incident technology solution that combines direct projection and side projection to achieve uniform illumination of the thick-walled light guide structure. Direct projection light source directly illuminates the front area of ​​the thick wall, while side projection light source supplements the illumination of the side and far-end areas through reflection or scattering inside the light guide structure. However, the dual-row light source layout increases the internal space requirement of the lamp, which restricts the modern vehicle light design that pursues flat and compact shapes.

[0036] The vehicle lamp assembly 100 of this application embodiment has a light-emitting unit 2 provided only on one side edge of the first light guide plate 1. The first light guide plate 1 extends at least partially along the direction of the first plane, and forms a light-inlet end face 11 on one side edge of the first plane. The two sides in the thickness direction are the light-emitting surface 12 and the reflective surface 13, respectively. When the light-emitting element 21 in the light-emitting unit 2 emits light towards the light-inlet end face 11, the light enters the first light guide plate. Due to the presence of the reflective surface 13, the light is continuously reflected inside the light guide plate and finally emitted from the light-emitting surface 12, achieving a good lighting effect. Because the light-emitting unit 2 is provided only on one side, the traditional bidirectional light-inlet scheme avoids the need to reserve space on the other side to place the light source and related components. The internal space requirement of the lamp is greatly reduced, improving the space utilization rate of the vehicle lamp assembly 100 inside the lamp and providing the possibility for compact and diversified design of vehicle lamps.

[0037] Meanwhile, due to the reduction of the light-emitting unit 2, the demand for the heat dissipation structure, driving circuit and secondary optical components of the light-emitting unit 2 is also reduced accordingly, further optimizing space utilization. By setting a single-sided light-emitting unit 2, the number of components in the vehicle lamp assembly 100 is reduced, and while achieving the light emission effect, space occupation is reduced, thus improving the space utilization rate of the vehicle lamp assembly 100.

[0038] According to some embodiments of this application, a vehicle headlight assembly 100 has a light-emitting surface 12 that is planar and a reflective surface 13 that has a first microstructure 131 for reflection. The first microstructure 131 is configured as a plurality of spaced-apart structures on the reflective surface 13, and each first microstructure 131 is configured as a protrusion or groove 111.

[0039] It is understandable that when the light from the light-emitting unit 2 enters the first light guide plate 1 from the light-inlet end face 11, it will propagate inside the light guide plate. Since the light-emitting surface 12 is constructed as a plane, the light propagates relatively regularly to the light-emitting surface 12. The multiple spaced first microstructures 131 on the reflective surface 13, whether protrusions or grooves 111, all play a role in changing the propagation path of the light.

[0040] When light encounters a protrusion or groove 111, it will be reflected or refracted, preventing light emitted from the light-emitting unit 2 from directly propagating to the light-emitting surface 12, which would cause local areas of the light-emitting surface 12 to be too bright. The first microstructure 131 can reflect the light to a relatively darker area, making the light more evenly distributed inside the light guide plate. If the light in a certain area is strong, when the light encounters a protrusion or groove 111 on the reflective surface 13 near that area, it will be reflected to a weaker area, thereby making the light intensity of the entire light-emitting surface 12 more uniform, avoiding the appearance of bright spots or dark areas, improving the uniformity of vehicle headlight illumination, and providing the driver with a clearer and more stable lighting vision.

[0041] According to some embodiments of this application, a vehicle headlight assembly 100 has a first microstructure 131 configured as a stepped pattern arranged sequentially on a reflective surface 13, and the angle between the light-emitting surface 12 and the light reflected by the reflective surface 13 is β and satisfies: 55°≤β≤90°.

[0042] Understandably, the first microstructure 131 is constructed as a stepped pattern arranged sequentially on the reflective surface 13. When light enters the first light guide plate 1 from the light-emitting unit 2 and reaches the reflective surface 13, the stepped pattern causes the light to be reflected at a fixed angle. Due to the sequential arrangement of the stepped pattern, the light undergoes multiple regular reflections on the reflective surface 13. Unlike ordinary planar reflection or random microstructure reflection, the stepped pattern can guide the light to the light-emitting surface 12 in a more orderly manner, making the distribution of light on the light-emitting surface 12 more uniform and avoiding random reflection of light that causes some areas to be too bright or too dark. The angle β between the light-emitting surface 12 and the light reflected by the reflective surface 13 satisfies 55°≤β≤90°. When β is within this range, it can ensure that the light has a sufficient exit angle to cover the effective lighting range required for vehicle driving. If the angle β is too small, the light will be too concentrated in the near distance area, resulting in insufficient lighting in the far distance in front of the vehicle, affecting the driver's judgment of road conditions in the distance. When the β angle is too large, the light becomes too diffused. Although the illumination range is wide, the light intensity per unit area decreases, which is also detrimental to seeing road details clearly. Within the range of 55°≤β≤90°, the light can ensure a certain illumination distance while maintaining sufficient light intensity within a reasonable range.

[0043] Meanwhile, the first microstructure 131 of the stepped pattern optimizes the number of reflections and angles of light on the reflective surface 13. When light is reflected at a suitable angle to the light-emitting surface 12, combined with the limitation of the β angle, more light can be emitted from the light-emitting surface 12 instead of being absorbed inside the light guide plate or reflected, refracted, or scattered in an unreasonable direction. If light cannot be effectively emitted when it propagates inside the light guide plate, it will cause energy waste. The vehicle lamp assembly 100 can convert more light energy into effective lighting light, reducing energy consumption while ensuring lighting effect, which meets the needs of vehicle energy conservation.

[0044] According to some embodiments of this application, a vehicle lighting assembly 100 further includes a concentrator 3, which is disposed between the light-emitting element 21 and the light-inlet end face 11, and is used to refract the light emitted by the light-emitting unit 2.

[0045] The light emitted by the light-emitting element 21 usually propagates in a divergent manner, with a large amount of light scattering in all directions. Only a portion of the light can directly enter the light-inlet end face 11 of the first light guide plate 1, resulting in low light utilization. The concentrator 3 is positioned between the light-emitting element 21 and the light-inlet end face 11, and can converge and guide the light emitted by the light-emitting element 21. The concentrator 3 is generally made of a material with optical refractive properties, and its shape and structure are designed. When the light is emitted from the light-emitting element 21, it enters the concentrator 3. The concentrator 3 uses the principle of refraction to change the direction of light propagation, making the originally divergent light more concentrated and directed towards the light-inlet end face 11. For some point light source light-emitting elements 21, the concentrator 3 can converge the light into a relatively narrow beam, greatly increasing the amount of light entering the light-inlet end face 11, improving the efficiency of light incident on the first light guide plate 1, and providing a more sufficient light foundation for subsequent lighting effects.

[0046] After being refracted by the concentrator 3, the light enters the light-inlet end face 11 in a more orderly manner. This has a positive impact on the initial distribution of light inside the first light guide plate 1. Inside the light guide plate, the initial distribution of light affects the final uniformity of light output. After the light enters the light-inlet end face 11 after being optimized by the concentrator 3, it can spread more evenly in all directions when propagating inside the light guide plate. This is because the concentrator 3 makes the light entering the light guide plate more concentrated and regular in terms of angle and position, reducing the local overly bright or dark areas caused by the chaotic initial distribution of light. The concentrator 3 ensures that the light has a good initial state inside the light guide plate, which helps to further adjust it through the first microstructure 131 of the reflective surface 13, etc., and finally achieve uniform light output from the light-emitting surface 12, thus improving the lighting quality.

[0047] In some embodiments of this application, the light concentrator 3 refracts the light emitted from the light-emitting unit 2 into light that is deflected within a range of 5° to 10° along a first direction, so as to improve the light-gathering efficiency of the light-emitting unit 2 entering the light-gathering end face 11.

[0048] According to some embodiments of this application, a vehicle headlight assembly 100 has a light-receiving end face 11 having a groove 111 for accommodating a light-receiving element 3.

[0049] The groove 111 on the light end face provides an installation position for the light concentrator 3. In the vehicle lamp assembly 100, the light concentrator 3 needs to maintain a specific relative positional relationship with the light-emitting element 21 and the light-inlet end face 11 in order to achieve effective refraction and guidance of light. The presence of the groove 111 allows the light concentrator 3 to be accurately placed in the predetermined position during installation, avoiding poor light refraction effect caused by installation deviation. This ensures that the light concentrator 3 can stably and accurately focus the light emitted by the light-emitting unit 2 onto the light-inlet end face 11, thereby improving the efficiency and accuracy of light entering the first light guide plate 1.

[0050] According to some embodiments of this application, in a vehicle headlight assembly 100, the angle between the light-emitting direction of the concentrator 3 and the reflective surface 13 is α, the maximum thickness of the first light guide plate 1 is T, and the distance between the light-inlet end and the other edge of the first light guide plate 1 is L; and the following conditions are met: .

[0051] The included angle α determined by the above formula allows the light emitted from the concentrator 3 to enter the first light guide plate 1 at an adjusted angle. When the light is emitted from the concentrator 3, it will interact more effectively with the reflective surface 13 as it propagates inside the first light guide plate 1 at this angle. During the propagation process inside the light guide plate, it can undergo multiple reflections on the reflective surface 13, making the light distribution inside the light guide plate more uniform. This avoids unreasonable reflections or refractions of the light inside the light guide plate, which could lead to light loss or uneven light output. By optimizing the light propagation path, the utilization efficiency of the light within the first light guide plate 1 is improved, laying the foundation for achieving a good lighting effect.

[0052] Meanwhile, the angle α is determined based on the size parameters (T and L) of the first light guide plate 1. This means that the internal space of the first light guide plate 1 can be fully utilized, and the light propagates at the angle α. The propagation path inside the light guide plate is optimized, and there will be no excessive concentration or deviation of the light within the light guide plate. This ensures that the light propagates and reflects within the entire effective space of the light guide plate, improving the utilization rate of the light guide plate space. In the design of the vehicle lamp assembly 100, making full use of the light guide plate space can make the structure of the vehicle lamp more compact, meeting the design requirements of modern vehicles for miniaturization and integration of vehicle lamps, and also helping to reduce the production cost of vehicle lamps.

[0053] The vehicle headlight assembly 100 according to some embodiments of this application further includes a second light guide plate 4, which extends along a second plane and is arranged parallel to a first plane. The second light guide plate 4 has an inner optical surface 41 and an outer optical surface 42 formed on both sides in the thickness direction, with the inner optical surface 41 facing the light-emitting surface 12. A second microstructure 43 is formed on at least one of the inner optical surface 41 and the outer optical surface 42.

[0054] Since the inner optical surface 41 of the second light guide plate 4 faces the light-emitting surface 12 of the first light guide plate 1, the light emitted from the first light guide plate 1 enters the second light guide plate 4. When the inner optical surface 41 or the outer optical surface 42 forms a second microstructure 43, these microstructures can readjust the light entering the second light guide plate 4. The second microstructure 43 can be constructed as a protrusion or a groove 111. When the light encounters these microstructures, it will be reflected, refracted, and scattered. The uneven light distribution that may exist after emitting from the first light guide plate 1 can be further homogenized by the action of the second microstructure 43 on the second light guide plate 4. This makes the spatial distribution of the light emitted from the second light guide plate 4 more reasonable, the lighting effect more uniform, and improves the overall lighting quality of the vehicle headlights, providing the driver with a clearer and more comfortable visual experience.

[0055] It should be noted that the second microstructure 43 can be constructed as a texture, which is a surface microstructure composed of periodically or randomly distributed micro-morphologies such as bumps, grooves, and particles, with scales ranging from nanometers to millimeters.

[0056] The vehicle headlight assembly 100 according to some embodiments of this application further includes: a shielding member 5, which covers one side of the light-emitting surface 12 of the first light guide plate 1, and at least a portion of the shielding member 5 extends to the light-inlet end face 11.

[0057] The shielding component 5 covers one side of the light-emitting surface 12 of the first light guide plate 1, effectively blocking the light emitted from the light-emitting surface 12 from scattering in unnecessary directions. When the headlights are working, some light from the light-emitting surface 12 of the first light guide plate 1 may not be emitted along the ideal lighting direction. These stray lights may interfere with the surrounding environment or other vehicles and pedestrians. The stray lights may also reflect into the eyes of drivers of oncoming vehicles, causing glare, affecting their vision, and increasing the risk of traffic accidents. The shielding component 5 can block these stray lights, making the light more concentrated in the direction of illumination, improving the effectiveness of the lighting, and reducing interference with others. At the same time, the presence of the shielding component 5 provides more possibilities for the appearance design of the headlights. The shielding component 5 can be customized according to the overall shape and design style of the vehicle, making it more coordinated and unified with the appearance of the vehicle. The shielding component 5 can adopt a design similar to the body color of the vehicle or have a unique shape, making the headlights look more beautiful and refined. In addition, the shielding component 5 can also hide some unsightly parts of the first light guide plate 1 and internal components, improving the overall visual effect of the headlights and enhancing the appearance appeal of the vehicle.

[0058] According to some embodiments of this application, a vehicle headlight assembly 100 includes a shielding member 5 comprising a shielding plate 51 and an overlapping plate 52. The shielding plate 51 is arranged parallel to the light-emitting surface 12 and extends from one side edge of the first light guide plate 1 toward the other side edge. The shielding plate 51 is connected to the edge of the second light guide plate 4. The overlapping plate 52 is disposed at one end of the shielding plate 51 near the light-inlet end face 11 and extends toward the light-inlet end face 11 and overlaps with the light-emitting unit 2.

[0059] The shield 51 is arranged parallel to the light-emitting surface 12 and extends from one side edge of the first light guide plate 1 to the other side edge. It can constrain the light emitted from the first light guide plate 1. Since the shield 51 is parallel to the light-emitting surface 12, it can effectively block the light emitted from the light-emitting surface 12 from scattering to the side, so that the light can be more concentrated and propagated along the preset direction. In the headlight illumination of the vehicle, the shield 51 can ensure that the light is mainly emitted forward to the road, avoiding the light from scattering to the sides and causing waste or interference to other vehicles and pedestrians.

[0060] Meanwhile, the shield 51 and the overlapping plate 52 together provide all-round protection for the components inside the vehicle lamp assembly 100, such as the first light guide plate 1, the second light guide plate 4, and the light-emitting unit 2. The shield 51 covers one side of the light-emitting surface 12 and can block dust, rain, sand and other external debris from directly contacting the first light guide plate 1 and the second light guide plate 4, preventing these debris from causing wear or contamination to the surface of the light guide plate, thereby ensuring the stable optical performance of the light guide plate. The overlapping plate 52 is set at one end of the shield 51 near the light-inlet end face 11 and overlaps with the light-emitting unit 2, which can protect the light-emitting unit 2 from the influence of the external environment. The overlapping plate 52 can also prevent dust and moisture from entering the light-emitting unit 2 to a certain extent, extending its service life. At the same time, both the overlapping plate 52 and the shield 51 have the effect of blocking light, which can effectively block the light emitted from the light-emitting surface 12 from scattering in other directions.
