Description

Technical Field

[0001] This application relates to the field of vehicle lighting technology, and more particularly to a vehicle lamp assembly and a vehicle. Background Technology

[0002] With the continuous development of the automotive industry and the increasing aesthetic demands of consumers, automotive lighting is no longer limited to traditional functional lighting tools, but is gradually evolving towards personalization, branding, and intelligence. Current technologies often use laser-engraved patterns to meet personalized needs for vehicle lights. However, the light emitted from the light source projects the laser-engraved pattern directly onto the target area (directly observed by road users), resulting in poor pattern uniformity and potentially causing glare for road users, thus affecting driving safety.

[0003] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] The following will describe in detail the vehicle lighting components and vehicle of this application with reference to the accompanying drawings and specific embodiments.

[0043] In existing technologies, laser-engraved patterns are often used to make vehicle lights meet personalized usage needs. However, the light emitted from the light source projects the laser-engraved pattern directly onto the target area (which is directly observed by road users). The resulting pattern has poor uniformity and is likely to cause glare to road users, affecting driving safety.

[0044] To address the aforementioned technical problems, this application provides a vehicle lamp assembly with a light outlet. The vehicle lamp assembly includes a light source module, a first light guide component, a laser-engraved pattern layer, and a bracket. The light source module is configured to emit light. The light incident surface of the first light guide component is disposed in the light emitting direction of the light source module. The laser-engraved pattern layer is disposed on either the light incident or light emitting surface of the first light guide component. A reflective layer is provided on the surface of the bracket, the reflective layer being disposed in the light emitting direction of the first light guide component, and the light outlet being disposed in the reflective direction of the reflective layer. This will be described in detail below.

[0045] See Figure 1 The vehicle headlight assembly has a light outlet and includes a light source module 10, a first light guide component 20, a laser-engraved pattern layer 40, and a bracket 30. The light source module 10 is configured to emit light. The light incident surface of the first light guide component 20 is disposed in the light emitting direction of the light source module 10, that is, the first light guide component 20 is configured to receive the light emitted by the light source module 10. The laser-engraved pattern layer 40 is disposed on the light incident surface or the light emitting surface of the first light guide component 20. The bracket 30 is spaced apart in the light emitting direction of the first light guide component 20. A reflective layer 31 is provided on the surface of the bracket 30 facing the first light guide component 20. The reflective layer 31 is disposed in the light emitting direction of the first light guide component 20, and the light outlet is disposed in the reflection direction of the reflective layer 31. That is, the reflective layer 31 is configured to receive the light emitted by the first light guide component 20 and reflect the light to the light outlet of the vehicle headlight assembly.

[0046] For ease of explanation, the following embodiments include a first direction and a second direction that are perpendicular to each other, wherein the first direction is as follows: Figure 1The middle direction is shown in Y, and the second direction is as follows. Figure 1 As shown in the X direction; in the practical application of the following embodiments, the second direction is the forward and backward direction of the vehicle (the direction of movement of the vehicle in a straight line), and the first direction is the vertical direction.

[0047] The laser-engraved pattern layer 40 is designed with specific patterns according to usage requirements. After light passes through the pattern of the laser-engraved pattern layer 40, it forms a specific pattern, which meets personalized usage needs and enriches the lighting forms of the vehicle headlight assembly. The light emitted from the light source module 10 needs to be reflected by the reflective layer 31 before it can be observed. The reflection by the reflective layer 31 helps to improve the uniformity of light and enhance the visual effect. Moreover, the light emitted from the light source module 10 is not directly observed by road users (the light observed by the human eye is the indirect light after being reflected by the reflective layer 31), which avoids glare to road users when it is lit, thereby reducing the risk of traffic accidents.

[0048] In some embodiments, the surface of the reflective layer 31 (the surface for reflection) can be provided with a homogenization structure. After light is reflected by the reflective layer 31, the uniformity is further improved, thereby enhancing visual recognition. In addition, the light rays incident on the reflective layer 31 ( Figure 1 From a downward perspective, some of the light does not hit the reflective layer 31 but shines directly onto the ground, which helps to illuminate the space near the vehicle body and enhances nighttime driving safety.

[0049] It should be noted that the light rays reflected by the reflective layer 31 are directed toward the light outlet (i.e., emitted along the second direction). The propagation direction of these light rays is not limited to being parallel to the second direction; rather, the overall trend of the light ray propagation direction is along the second direction. Figure 1 From a visual perspective, the light reflected by the reflective layer 31 propagates from left to right. That is, the propagation direction of the light reflected by the reflective layer 31 can be parallel to the second direction or set at an angle (less than 30°) to the second direction, both of which fall within the protection scope of this application.

[0050] In addition, in practical applications, the bracket 30 can be an opaque decorative ring for mounting the first light guide component 20, or other components opposite to the first light guide component 20. By utilizing the existing components of the vehicle headlight, the light propagation path can be adjusted, avoiding the occupation of the internal space of the vehicle headlight, and the structure is simple.

[0051] It is worth mentioning that in some embodiments, the vehicle light assembly can also be used as a welcome light. In this case, the light reflected by the reflective layer 31 is directed toward the ground. That is, in this application, the second direction is vertical. Different patterns are set by the laser engraving pattern layer 40 to ultimately achieve different welcome patterns and meet personalized usage needs.

[0052] See Figure 2The first light guide component 20 is made of homogenized material, and the laser-engraved pattern layer 40 is disposed on the light-incident surface of the first light guide component 20.

[0053] The first light guide component 20 is made of homogenizing material, which helps to improve the uniformity of emitted light. The laser-engraved pattern layer 40 is set on the light-incident surface of the first light guide component 20, that is, the light passes through the laser-engraved pattern layer 40 first and then is homogenized. This light processing method makes the light efficiency higher. The light first acts directly on the laser-engraved pattern for modulation (forming a pattern) and then is homogenized, which reduces the light loss caused by the light going through the homogenization process first (the first light guide component 20 made of homogenizing material has the loss of light absorption and scattering, that is, more light forms the pattern).

[0054] In addition, the light forms a pattern after passing through the laser-engraved pattern layer 40. Even if the light source is uneven, the light can be effectively homogenized and mixed after passing through the first light guide component 20. This smooths out the rough edges of the pattern itself and the local differences in brightness caused by uneven light source, ultimately presenting a uniform and soft pattern light spot. This makes the pattern look softer and the transition smoother, forming a uniformly luminous overall light shape. In practical applications, it can be used in situations where sharp edges are not required and only a soft light spot or mark is needed (such as ambient lighting).

[0055] It is worth mentioning that in the scheme where light first passes through the laser-engraved pattern layer 40 to form a pattern and then is homogenized, the homogenization effect of the first light guide component 20 does not need to be very demanding. It is sufficient to achieve the required diffusion angle and uniformity, which is conducive to reducing manufacturing costs.

[0056] See Figure 3 The light-incident surface of the first light guide component 20 is provided with a homogenization layer 50, and the laser-engraved pattern layer 40 is disposed on the light-out surface of the first light guide component 20.

[0057] In this embodiment, the light first passes through a uniform layer (in some embodiments, this could be an optical texture or a uniform paint layer, etc., which is not specifically limited here) and then through a laser-engraved pattern layer 40 to form a pattern. The uniform light effect is stable. After the uniform layer 50 eliminates the non-uniformity of the light source, the light then passes through the laser-engraved pattern layer 40. This results in a clearer and sharper edge to the pattern (the angle distribution of the uniform light incident on the pattern is narrower and more consistent, reducing the scattering and diffraction of light at the edge of the pattern, making the "projection" effect of the pattern more accurate), making the transition between light and dark areas steeper and the contrast higher. For example, in practical applications, this can be used to display car logos, which helps to improve the visual recognition of the car logo.

[0058] See Figure 4 The light-incident surface of the first light guide component 20 is covered with a homogenizing film 60, and a laser-engraved pattern layer 40 is disposed on the surface of the homogenizing film 60 facing the first light guide component 20.

[0059] The homogenizing film 60 can be connected to the first light guide component 20 by adhesive bonding. Before assembly, the two are two independent parts that can be processed separately, which improves processing efficiency. Furthermore, if the homogenizing film 60 is damaged, it can be replaced separately, which reduces the cost of use.

[0060] In addition, the function of the homogenizing film 60 is to homogenize the light. After the light is homogenized by the homogenizing film 60, it passes through the laser engraving pattern layer 40 to form a pattern. The specific analysis is similar to that of the aforementioned embodiments, and will not be repeated here.

[0061] In some embodiments, a thin injection-molded part may be laid on the light-incident surface of the first light guide component 20 to homogenize the light, but this is not the only option.

[0062] In some embodiments, the light source module 10 includes a light-emitting surface 121 and a side baffle 122, the side baffle 122 surrounding the periphery of the light-emitting surface 121 (e.g., Figure 7 (As shown); the vehicle headlight assembly also includes a homogenizing element 70, which is disposed on the side of the first light guide component 20 and the side baffle 122 near the light outlet of the vehicle headlight assembly, and the light emitting surface of the homogenizing element 70 faces the light outlet; the light source module 10 and the first light guide component 20 are arranged sequentially along a first direction; in the first direction, the homogenizing element 70 is at least partially located between the light source module 10 and the first light guide component 20.

[0063] In this embodiment, the homogenizing element 70 is a light-transmitting element, and light can be homogenized after passing through the homogenizing element 70. After the light source module 10 is lit, since the homogenizing element 70 is at least partially located below the light-emitting surface 121 (ensuring that the homogenizing element 70 can receive stray light emitted from the light-emitting surface), some stray light will be directed towards the homogenizing element 70. This stray light is homogenized by the homogenizing element 70 and emitted to the right, which can provide background light for the pattern reflected by the reflective layer 31, enhancing the overall visual sense of depth, such as... Figure 8 As shown.

[0064] In some embodiments, a projection surface η perpendicular to the second direction is set, and the orthographic projections of the light source module 10 and the first light guide component 20 on the projection surface η are located within the orthographic projection of the homogenizer 70 on the projection surface η.

[0065] That is, the homogenizing element 70 is located on the right side of the first light guide component 20 and the light source module 10. Figure 1 (View angle) The homogenizing component 70 can block the light source module 10 and the first light guide component 20, so that the internal structure cannot be observed when the vehicle light assembly is static, thus improving the static visual effect and aesthetics.

[0066] It is worth mentioning that, in some embodiments, the use of the homogenizer 70 can help improve the versatility of vehicle lights.

[0067] For example, in some embodiments, the two (the first light guide component 20 and the homogenizer 70) can correspond to modules with different functions. The light emitted from the homogenizer 70 can be used for turn signals, and the light emitted from the first light guide component 20 can be used for brake lights after being reflected by the reflective layer 31. In this embodiment, the light source module 10 includes yellow LEDs (for turn signals) and red LEDs (for brake lights), and the two types of LEDs can be lit separately (providing different colors of light according to usage requirements). In other embodiments, it can also be a module design with other functions, not limited to this; it simplifies the internal structure of the vehicle headlight, reduces the volume occupied inside the vehicle headlight, and is beneficial to the arrangement of other components inside the vehicle headlight.

[0068] It is also worth mentioning that the light emitted from the homogenizer 70 is mainly emitted along the second direction, and the light emitted from the first light guide component 20, after being reflected by the reflective layer 31, is also mainly emitted along the second direction, thus separating the light emitted by the two (e.g. Figure 1 As shown, the light emitted from the first light guide component 20 is first emitted downwards for a certain distance and then reflected along the second direction, which avoids mutual interference between the emitted light and improves the overall lighting effect.

[0069] In some embodiments, along the first direction, the two ends of the homogenizer 70 are respectively located on the side where the light source module 10 and the first light guide component 20 are far apart from each other.

[0070] With this configuration, the light source module 10 faces the light outlet ( Figure 1 The stray light leaking out (from center to right) can be largely received by the homogenizer 70, thereby utilizing the stray light to form background light and enhance the stereoscopic visual effect of the main pattern (i.e., the pattern reflected by the reflective layer 31). At the same time, in some embodiments, the portion of the homogenizer extending to the bottom of the first light guide component 20 can block the top edge of the bracket 30, so that its internal structure is not visible when looking at the lamp from outside the vehicle, which helps to improve the overall visual effect.

[0071] In some embodiments, along the first direction, the homogenizer 70 may also be connected at one end to the first light guide component 20, and the other end of the homogenizer 70 may be located on the side of the light source module 10 away from the first light guide component 20, and is not limited thereto.

[0072] In some embodiments, the first light guide component 20 and the homogenizer 70 are integrally disposed.

[0073] The two components (the first light guide component 20 and the homogenizing component 70) are integrated, which helps to improve the accuracy of their relative positions and thus improve the overall lighting effect. The integrated design also facilitates processing and shaping, improving production efficiency. At the same time, during loading and unloading, only one operation is needed to disassemble and assemble the two components, improving the efficiency of disassembly and assembly.

[0074] In some embodiments, the light source module 10 includes a mounting plate 11 and a first LED bead 12. The mounting plate 11 and the first light guide component 20 are spaced apart along a first direction, and the first LED bead 12 and the homogenizer 70 are arranged sequentially along a second direction. The first LED bead 12 is disposed on the surface of the mounting plate 11 facing the first light guide component 20, and the first LED bead 12 is configured to provide light to the first light guide component 20. If the first LED bead 12 is in the form of an LED, its divergence angle is about 120° (the characteristic of LEDs is that most of the light is concentrated within a range of about 120°), and the main light emission direction of the first LED bead 12 is parallel to the first direction. The light incident surface of the first light guide component 20 is perpendicular to the light incident surface of the homogenizer 70. The distance between the first LED bead 12 and the homogenizer 70 in the second direction is d1, and the distance between the first LED bead 12 and the first light guide component 20 in the first direction is d2, satisfying: like Figure 7 As shown, the light emitted by the first LED bead 12 is concentrated within a 120° range, with the outermost light rays passing precisely at the junction of the first light guide component 20 and the homogenizing component 70.

[0075] When the ratio of d2 / d1 is greater than When (d2 increases or d1 decreases), some of the light rays (the main light rays) within the divergence angle of the first LED bead 12 will directly hit the homogenizer 70, resulting in the homogenizer 70 containing not only stray light but also direct light rays from the first LED bead 12. This significantly increases the brightness of the background light projected through the homogenizer 70. Simultaneously, the amount of light projected from the first LED bead 12 to the first light guide component 20 (i.e., the laser-engraved pattern layer 40) to form the main pattern decreases, leading to lower brightness of the main pattern, reduced contrast with the surrounding background light, and poor overall lighting effect. In addition, the applicant found that when the ratio of d2 / d1 is less than 1 / 5, the distance between the first lamp bead 12 and the first light guide component 20 is too close (i.e., the d2 value is too small), which is not conducive to the heat dissipation of the first lamp bead 12. Alternatively, the distance between the first lamp bead 12 and the homogenizing component 70 is too large (i.e., the d1 value is too large), which will occupy more space in the second direction. The second direction is usually the length direction of the vehicle body. When the d1 value is too large, it will encroach on more space in the vehicle body.

[0076] It should be noted that in this embodiment, the first LED bead 12 is configured to provide light to the first light guide component 20, that is, the main light of the first LED bead 12 is directed toward the first light guide component 20. In practical applications, when the first LED bead 12 is lit, there is also a small amount of light outside the divergence angle of the first LED bead 12. This part of the light is directed toward the homogenizing component 70 and is homogenized by the homogenizing component 70 to form a weak background light around the main pattern (that is, in this embodiment, the first LED bead 12 includes the aforementioned light-emitting surface 121 and the side baffle 122). See the aforementioned embodiment for details, which is beneficial to improving the visual sense of hierarchy.

[0077] See Figure 5 In some embodiments, the light source module 10 includes a mounting plate 11, a first LED bead 12, and a second LED bead 13. The mounting plate 11 and the first light guide component 20 are spaced apart along a first direction. The first LED bead 12 is configured to provide light to the first light guide component 20, and the second LED bead 13 is configured to provide light to the homogenizer 70. The first LED bead 12 and the second LED bead 13 are respectively disposed on opposite sides of the mounting plate 11.

[0078] The first LED bead 12 and the second LED bead 13 are located on opposite sides of the mounting plate 11. The two types of LED beads (the first LED bead 12 and the second LED bead 13, the same below) emit light in opposite directions, and the light between them will not affect each other, which is conducive to improving the overall lighting effect.

[0079] In this embodiment, the first LED bead 12 is disposed below the mounting plate 11 and is used to emit light to the first light guide component 20. The light emitted by the first LED bead 12 is not blocked and has a large illumination range.

[0080] In some embodiments, the light emitted by the two types of LED beads can be adjusted by components such as the reflector 14, and the design can be carried out according to the actual use. Specifically, the light source module 10 also includes a reflector 14 and a blocking block 15, both of which are disposed on the mounting plate 11. The reflector 14 is configured to receive the light emitted by the second LED bead 13 and reflect the light to the homogenizer 70. The blocking block 15 is disposed between the second LED bead 13 and the homogenizer 70.

[0081] By setting the reflector 14, the light from the second LED 13 can be directed toward the homogenizer 70, which improves the utilization rate of the light from the second LED 13 and helps to improve the lighting effect. At the same time, the blocking block 15 is set between the second LED 13 and the homogenizer 70. The blocking block 15 can block the direct light (the light emitted from the second LED 13 and directed directly toward the homogenizer 70), which helps to avoid glare or affect the light effect caused by the direct light and improve the lighting effect.

[0082] In some embodiments, the light source module 10 further includes a shielding ring 16 disposed on the light-incident side of the homogenizer 70; the shielding ring 16 is provided with a light-transmitting hole 161, which is configured to guide the light reflected by the reflector 14 to the homogenizer 70.

[0083] By setting the shielding ring 16, the light reflected by the reflector 14 can be constrained and modified to improve the lighting effect; and the light-transmitting hole 161 can be designed into different shapes according to actual needs to meet personalized usage requirements.

[0084] It is worth mentioning that, in Figure 5 In the embodiment shown, the shielding ring 16 can also block the light emitted by the first lamp bead 12, preventing the light emitted by the first lamp bead 12 from directly hitting the homogenizer 70 and avoiding interference with the lighting of the homogenizer 70.

[0085] See Figure 6 In some embodiments, the first LED 12 and the second LED 13 are disposed on the side of the mounting plate 11 facing the first light guide component 20.

[0086] In this embodiment, the first LED 12 and the second LED 13 are arranged on the same side of the mounting plate 11, eliminating the need for arrangement on both sides of the mounting plate 11. This helps to reduce the vertical dimension of the light source module 10, reduce space occupation, and facilitate the flattening design of the vehicle headlight. At the same time, since the two types of LEDs are arranged on the same side, the heat generated is on the other side, which helps to improve the service life of the two types of LEDs.

[0087] It should be noted that in order to prevent the two types of LED beads from interfering with each other, a light-blocking component can be set between the two types of LED beads. In some embodiments, the reflector 14 can be used as a light-blocking component, which will not be described in detail here.

[0088] In some embodiments, the angle between the reflective layer 31 and the horizontal plane λ is β, which satisfies: 30°≤β≤60°, such as 30°, 40°, 50°, 60°, etc.

[0089] When the value of β is less than 30°, the reflective layer 31 tends to be set horizontally, and the light emitted from the first light guide component 20 will be reflected upward, which is not conducive to the long-distance (first direction) propagation of light and affects the lighting effect; when the value of β is greater than 60°, the reflective layer 31 tends to be set vertically, and the light emitted from the first light guide component 20 will be reflected downward, which is also not conducive to the long-distance (first direction) propagation of light.

[0090] Of course, in some embodiments, the value of β can be other than the values ​​mentioned above. For example, when the value of β is 70°, more light is reflected closer to the ground near the vehicle body, which is beneficial to improving the road lighting effect near the vehicle body, making it easier to observe the vehicle body position at night and improving driving safety, and is not limited to this.

[0091] It should be noted that the vehicle light assembly also includes a housing 90 and a second light guide component 100. The second light guide component 100 covers the opening of the housing 90 to seal the internal space of the housing 90. The various components included in the aforementioned vehicle light assembly are housed in the internal space of the housing 90.

[0092] On the other hand, this application also relates to a vehicle including any of the aforementioned headlight components.

[0093] Using the technical solution provided in this application embodiment, the laser-engraved pattern layer 40 is set with a specific pattern according to the usage requirements. After the light passes through the pattern of the laser-engraved pattern layer 40, a specific pattern is formed, which meets the personalized usage requirements and enriches the lighting forms of the vehicle light assembly. The light emitted from the light source module 10 needs to be reflected by the reflective layer 31 before it can be observed. The reflection by the reflective layer 31 helps to improve the uniformity of light and improve the visual effect. Moreover, the light emitted from the light source module 10 is not directly observed by road users, avoiding glare to road users when it is lit, thereby reducing the risk of traffic accidents.
