Description
Technical Field
[0001] This utility model relates to the field of lighting technology, and in particular to a vehicle lamp assembly, a light-emitting structure, and a vehicle lamp. Background Technology
[0002] The light emission and illumination functions of automotive headlights typically rely on the cooperation of internal optical components such as light sources and light guides. Light emitted from the light source travels through the light guide towards the lampshade, forming a visible light pattern. Near the light source, a region of significant contrast (light spot) is created at the end of the light guide, forming a noticeable area of intense light on the surrounding trim. This is usually addressed by adding a cover at this end to conceal the light guide's tip, preventing consumers from observing it. However, some headlights with unique designs, such as those resembling a "hammerhead shark," make it difficult to cover the light guide's tip. When the headlight is on, consumers can clearly see the significant contrast in light and the intense area of light on the trim. Both of these optical defects negatively impact the overall appearance of the headlight.
[0003] Therefore, it is necessary to provide a vehicle lamp assembly, a light-emitting structure, and a vehicle lamp to solve or at least alleviate the aforementioned technical problems. Utility Model Content
[0004] The main purpose of this utility model is to propose a vehicle lamp assembly, a light-emitting structure, and a vehicle lamp, which is aimed at solving the technical problem of optical defects in the end part of the light guide and its surrounding area, for vehicle lamps where it is impossible to set a cover to block the light guide at the end part.
[0005] To achieve the above objectives, this utility model proposes a vehicle light assembly, comprising:
[0006] The first light guide includes a first body and a first mounting part. The first body includes a first light-incident end and a first light-outceasing side and a first reflective side disposed opposite to each other. Along the direction away from the first light-incident end, the first reflective side is provided with a first optical texture, a first light-filling tooth and a first light-guiding tooth distributed in sequence. The first light-filling tooth and the first light-guiding tooth are both used to reflect the light in the first body toward the first light-outceasing side.
[0007] The first main body is mounted on the decorative ring via the first mounting part. The decorative ring includes a high-gloss part. Light rays from the first light guide directed onto the decorative ring fall into the high-gloss part. The surface of the high-gloss part is provided with a leather texture structure. Both the leather texture structure and the first optical texture are used to achieve diffuse reflection of light.
[0008] In one embodiment, the headlight assembly uses a light source board as the light source. The headlight assembly also includes a second light guide, which includes a second body and a second mounting portion. The second body is mounted on the trim ring via the second mounting portion. The second body is mounted above the first body. The second body includes a second light-incident end, and both the second light-incident end and the first light-incident end face the light source board.
[0009] The second main body includes a second light-emitting side and a second light-reflecting side. Along the direction that gradually moves away from the second light-incident end, the second light-reflecting side is provided with a second supplementary light tooth and a second light guide tooth arranged in sequence. The second supplementary light tooth and the second light guide tooth are both used to reflect the light in the second main body toward the second light-emitting side.
[0010] Definition: The distance between the first light-incident end and the first supplementary light tooth is a, and the distance between the second light-incident end and the second supplementary light tooth is b;
[0011] Then a and b satisfy: 5mm≤a≤15mm, 5mm≤b≤15mm.
[0012] The second body also includes a second optical texture, which is disposed on the side of the second supplementary light tooth near the second light-incident end, and the second optical texture is used to achieve diffuse reflection of light.
[0013] The cross-sections of the first body and the second body are circular;
[0014] Alternatively, the cross-sections of the first and second main bodies are rectangles with rounded corners.
[0015] This utility model also proposes a light-emitting structure, including the vehicle lamp assembly described in the above embodiments. The light-emitting structure further includes the light source plate. The light source plate is provided with a first lamp bead and a second lamp bead for emitting light. The first lamp bead is disposed facing the first light-incident end, and the second lamp bead is disposed facing the second light-incident end.
[0016] In one embodiment, the light-emitting structure further includes a lampshade, which covers the vehicle lamp assembly, with both the first light-emitting side and the second light-emitting side facing the lampshade.
[0017] In one embodiment, the lampshade includes a first patterned portion and a second patterned portion. The first light-emitting side is disposed opposite to the first patterned portion, and the second light-emitting side is disposed opposite to the second patterned portion. Both the first patterned portion and the second patterned portion are provided with a plurality of parallel stripe structures. The stripe structures are used to cover the first main body and the second main body, and the stripe structures allow light to pass through.
[0018] This utility model also proposes a vehicle lamp, including the light-emitting structure described in the above embodiments.
[0019] According to the technical solution provided by this utility model, the vehicle headlight assembly includes a first light guide and a decorative ring. The first light guide includes a first main body and a first mounting part. The first main body includes a first light-incident end and a first light-emitting side and a first reflective side arranged opposite to each other. Along the direction gradually away from the first light-incident end, the first reflective side is provided with a first optical texture, a first supplementary light tooth, and a first light guide tooth arranged in sequence. The first supplementary light tooth and the first light guide tooth are both used to reflect the light in the first main body toward the first light-emitting side. The first main body is mounted on the decorative ring through the first mounting part. The decorative ring includes a high-brightness part. The light from the first light guide to the decorative ring falls into the high-brightness part. The surface of the high-brightness part is provided with a textured structure. The textured structure and the first optical texture are both used to achieve diffuse reflection of light. This design allows the first supplementary light teeth to reflect light from the first main body towards the portion near the first light-incident end on the first light-emitting side. This makes the brightness of this portion essentially the same as the brightness of the first light-emitting side relative to the first light-guiding teeth, thus eliminating uneven brightness spots near the first light-incident end of the first main body. Simultaneously, by setting the first optical texture, light emitted from the first main body towards the trim ring undergoes diffuse reflection, reducing the possibility of high-brightness areas forming on the trim ring, or at least reducing the area of high-brightness areas. Furthermore, the areas on the trim ring with high-brightness areas are called high-brightness sections. By setting a textured structure on the surface of these high-brightness sections, light falling on them is reflected in different directions, thereby reducing the brightness of these sections and making their brightness as consistent as possible with the surrounding trim ring, ultimately eliminating high-brightness areas on the trim ring surface. Through these design features, the obvious contrast between light and dark spots formed at the end of the first main body and the strong light areas formed on the trim ring are eliminated, ensuring that the appearance quality of the headlights is not affected.

[0036] Headlights, as a crucial component of automobiles, function not only to illuminate roads and ensure driving safety but also play a vital role in the vehicle's exterior design. The light emission and illumination functions of headlights rely on the coordinated work of internal optical components such as light sources and light guides. Light emitted from the light source, propagated and reflected by the light guide, is evenly directed towards the lampshade, ultimately forming the bright light pattern visible to the naked eye. However, some unavoidable optical defects exist in the design and application of light guides. Particularly at the end of the light guide near the light source, where the light guide teeth meet, the area without teeth emits a dimmer light, while the area with teeth emits a brighter light, often resulting in a bright spot with a significant contrast between light and dark. Simultaneously, because this area usually has a mounting structure, some light does not meet the condition of total internal reflection near the mounting structure, causing some light to leak around the structure. This leaked light falls on the surface of the trim ring, forming a bright area of intense light. In practical applications, the phenomenon of light spots and bright areas often occur simultaneously.
[0037] To conceal these two optical defects, those skilled in the art typically employ the method of adding a cover to the end of the light guide to shield them. However, based on the applicant's research and summary of various automotive lighting projects, it has been found that with the continuous innovation of automotive design concepts and consumers' increasing pursuit of personalized appearance, some automotive lights with special appearance designs have emerged, such as "hammerhead shark" shaped lights. The unique design style of these lights makes it extremely difficult, or even impossible, to install a cover at the end of the light guide for shielding. When these lights are illuminated, consumers can clearly observe the bright and dark spots with significant contrast at the end of the light guide, as well as the strong light area formed on the trim ring. These two optical defects affect the appearance quality of the lights, reducing consumer satisfaction and willingness to purchase. Therefore, for automotive lights with special shapes similar to "hammerhead sharks," how to eliminate these two optical defects and improve the appearance quality of the lights has become a technical bottleneck that urgently needs to be overcome in the field of automotive lighting design and manufacturing.
[0038] In view of this, the present invention proposes a vehicle lighting assembly to solve or at least alleviate the above-mentioned problems.
[0039] Please see Figures 1 to 3 In one embodiment of the present invention, the vehicle headlight assembly 100 includes a first light guide 1 and a decorative ring 2. The first light guide 1 includes a first body 11 and a first mounting portion 12. The first body 11 includes a first light-incident end 111 and a first light-emitting side 112 and a first reflective side 113 arranged opposite to each other. Along the direction gradually away from the first light-incident end 111, the first reflective side 113 is provided with a first optical texture (not shown in the figure), a first supplementary light tooth 114 and a first light guide tooth 115 arranged in sequence. The first supplementary light tooth 114 and the first light guide tooth 115 are both used to reflect the light in the first body 11 toward the first light-emitting side 112. The first body 11 is mounted on the decorative ring 2 through the first mounting portion 12. The decorative ring 2 includes a high-brightness portion 21. The light from the first light guide 1 toward the decorative ring 2 falls into the high-brightness portion 21. The surface of the high-brightness portion 21 is provided with a textured structure. The textured structure and the first optical texture are both used to achieve diffuse reflection of light.
[0040] Specifically, in this embodiment, please refer to... Figure 1 and Figure 2The first mounting part 12 is mounted on the side of the first main body 11 near the first light-incident end 111. After the light enters the first main body 11 through the first light-incident end 111, the light will continuously propagate forward along the extension direction of the first main body 11. At the part where the first light guide tooth 115 is provided, the light will be reflected to the first light-emitting side 112. The part of the first light-emitting side 112 opposite to the first light guide tooth 115 is defined as the main light-emitting side, and the brightness of the main light-emitting side is higher. To improve the brightness of the portion of the first main body 11 near the first light-incident end 111 and eliminate light spots caused by brightness differences, a first supplementary light tooth 114 is extended from the side of the first light guide tooth 115 near the first light-incident end 111. The portion of the first light-emitting side 112 opposite to the first supplementary light tooth 114 is designated as the edge light-emitting side. The first supplementary light tooth 114 can reflect light towards the edge light-emitting side, thereby improving the brightness of the edge light-emitting side and making the brightness of the edge light-emitting side more consistent with the brightness of the main light-emitting side, thus eliminating the brightness difference between the two areas and eliminating the light spots present in the first light guide 1. Part of the light emitted from the first main body 11 towards the decorative ring 2 is emitted from the edge of the first supplementary light tooth 114 near the first light-incident end 111, and the other part is emitted from the joint between the first mounting portion 12 and the first main body 11. For the light emitted from the edge of the first supplementary light tooth 114, this embodiment provides a first optical texture at the part of the first supplementary light tooth 114 near the first light-incident end 111. The first optical texture can achieve diffuse reflection of light, and the light emitted through the first optical texture will not form bright light bars or spots on the decorative ring 2. For the light emitted from the joint between the first mounting part 12 and the first main body 11 towards the decorative ring 2, in this embodiment, the position where this part of the light falls on the decorative ring 2 is found through numerical simulation and experiment, and is denoted as the bright part 21. A textured structure is added to the surface of the bright part 21 to uniformly reflect the light falling into the bright part 21 in all directions, thereby eliminating the bright light bars or spots present in the bright part 21. Through the above two improvement measures, the bright area present on the decorative ring 2 is eliminated.
[0041] The technical solution of this embodiment improves the structure of the first light guide 1 and the decorative ring 2, so that the first supplementary light tooth 114 can reflect the light in the first body 11 towards the part near the first light-incident end 111, so that the brightness of this part is basically the same as the brightness of the part where the first light guide tooth 115 is provided, and no light spots caused by uneven brightness will be generated in the part of the first body 11 near the first light-incident end 111. At the same time, by setting the first optical texture, the light emitted from the first body 11 towards the decorative ring 2 will be diffused, thereby reducing the possibility of forming a bright area on the decorative ring 2, or at least reducing the area of the bright area. In addition, the part of the decorative ring 2 where there is a bright area is defined as the bright part 21. By setting a textured structure on the surface of the bright part 21, the light falling on the bright part 21 is reflected in different directions, thereby reducing the brightness of the bright part 21 and making the brightness of the bright part 21 as consistent as possible with the brightness of the surrounding decorative ring 2, and finally eliminating the bright area on the surface of the decorative ring 2. The above settings eliminate the bright and dark contrast of light spots formed at the end of the first main body 11 and the strong light area formed on the trim ring 2 (the strong light area usually includes bright light bars or light spots), thus ensuring that the appearance quality of the headlights is not affected.
[0042] Please continue reading. Figures 1 to 3 In one embodiment of this utility model, the vehicle headlight assembly 100 uses a light source board as the light source, and also includes a second light guide 3. The second light guide 3 includes a second main body 31 and a second mounting part 32. The second main body 31 is mounted on the trim ring 2 through the second mounting part 32. The second main body 31 is mounted above the first main body 11 (see [reference]). Figure 1 (In the direction indicated by the middle arrow X), the second body 31 includes a second light-incident end 311, which, along with the first light-incident end 111, faces the light source plate. In this embodiment, the combination of the first light guide 1 and the second light guide 3 makes the appearance of the headlight more unique, thereby increasing the design appeal of the headlight. The first body 11 and the second body 31 share the same light source plate, reducing the number of components in the headlight and facilitating a more compact internal design. Furthermore, in this embodiment, the vehicle's lighting module is located in the middle of the first light guide 1 and the second light guide 3. Sharing a single light source plate reduces the distance between the ends of the first body 11 and the second body 31 near the light source plate, creating a "corner of the eye" shape at the ends of the first body 11 and the second body 31 that are close to each other, making the headlight's appearance more dynamic.
[0043] Furthermore, in one embodiment of this utility model, the second body 31 includes a second light-emitting side 312 and a second reflective side 313. Along a direction gradually moving away from the second light-incident end 311, the second reflective side 313 is provided with sequentially distributed second supplementary light teeth 314 and second light-guiding teeth 315. Both the second supplementary light teeth 314 and the second light-guiding teeth 315 are used to reflect light from the second body 31 towards the second light-emitting side 312. Please refer to [link / reference]. Figure 2 and Figure 3 The second supplementary light tooth 314 is disposed in the second main body 31 closer to the second light-incident end 311, so that the second supplementary light tooth 314 can reflect light to the part of the second light-emitting side 312 closer to the second light-incident end 311, so that the brightness of this part is consistent with the brightness of the rest of the second light-emitting side 312, thereby preventing light spots caused by brightness difference in the part of the second main body 31 closer to the second light-incident end 311. In this embodiment, the light emitted from the connection between the second main body 31 and the second mounting part 32 to the trim ring 2 falls into the high-brightness part 21 of the trim ring 2. Since the high-brightness part 21 already has a textured structure, the addition of the second light guide 3 will not form new high-brightness light bars or light spots on the trim ring 2, thus ensuring the overall appearance quality of the headlight.
[0044] Furthermore, please refer to Figure 4 and Figure 5In one embodiment of this utility model, the distance between the first light-incident end 111 and the first supplementary light tooth 114 is defined as 'a', and the distance between the second light-incident end 311 and the second supplementary light tooth 314 is defined as 'b'. Then, a and b satisfy: 5mm ≤ a ≤ 15mm, 5mm ≤ b ≤ 15mm. The specific lengths of a and b can be determined through experiments and numerical simulations. It should be noted that if the lengths of a and b are greater than 15mm, light spots caused by the difference in brightness will still exist at the ends of the first body 11 and the second body 31 near the light source plate, and these spots will be easily observed by consumers. If the lengths of a and b are less than 5mm, the extension lengths of the first supplementary light tooth 114 and the second supplementary light tooth 314 are too long. Taking the case where a < 5mm as an example, light enters the first body 11 through the first light-incident end 111 and propagates in a direction away from the light source plate. When the light passes through the first supplementary light tooth 114, some of the light is reflected out towards the first light-outceasing side 112. The longer the length of the first supplementary light tooth 114, the greater the light energy loss at the location where the first supplementary light tooth 114 is set, resulting in only a small amount of light propagating to the end of the first body 11 away from the light source plate, thus making the end part of the first body 11 darker. The longer the extension lengths of the first supplementary light tooth 114 and the second supplementary light tooth 314, the greater the light energy loss at the first supplementary light tooth 114 and the second supplementary light tooth 314, which may lead to the end parts of the first body 11 and the second body 31 having too low brightness, thereby affecting the uniformity of light emission from the first body 11 and the second body 31. Therefore, in this embodiment, limiting the lengths of both a and b to no less than 5 mm can prevent the extension lengths of the first supplementary light tooth 114 and the second supplementary light tooth 314 from being too long, thereby preventing the ends of the first body 11 and the second body 31 from being too dark, and thus ensuring that the brightness of the first body 11 and the second body 31 tends to be consistent when emitting light.
[0045] In one embodiment of this utility model, the second body 31 further includes a second optical texture (not shown in the figure). The second optical texture is disposed on the side of the second supplementary light tooth 314 near the second light-incident end 311. The second optical texture is used to achieve diffuse reflection of light. The second optical texture is used to uniformly refract the light emitted by the second body 31 towards the decorative ring 2 in various directions, and to prevent the light leaking out of the second body 31 from forming bright light bars or spots on the surface of the decorative ring 2.
[0046] In one embodiment of this invention, the cross-sections of the first body 11 and the second body 31 are circular; or, the cross-sections of the first body 11 and the second body 31 are rectangles with rounded corners. Circular cross-sections or rectangular cross-sections with rounded corners can effectively reduce reflection loss during light propagation. Since these two boundaries have no sharp corners, light can transition more smoothly during total internal reflection, avoiding light energy loss caused by abrupt angle changes.
[0047] This utility model also proposes a light-emitting structure, which includes a vehicle lamp assembly 100. The specific structure of the vehicle lamp assembly 100 is as described in the above embodiments. Since this light-emitting structure 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, and will not be described in detail here. The light-emitting structure also includes a light source board, which is provided with a first LED and a second LED for emitting light. The first LED faces the first light-incident end 111, and the second LED faces the second light-incident end 311. By setting two LEDs on the light source board corresponding to different light-incident ends, light can be introduced into the first body 11 and the second body 31 more evenly. This design can effectively avoid the problem of uneven light intensity that may be caused by a single LED, making the light distribution in the first body 11 and the second body 31 more uniform, thereby improving the overall light-emitting effect.
[0048] Furthermore, in one embodiment of this utility model, the light-emitting structure also includes a lampshade, which covers the vehicle lamp assembly 100. The first light-emitting side 112 and the second light-emitting side 312 both face the lampshade. That is, the light-emitting structure is entirely disposed inside the lampshade, which can prevent the intrusion of external dust or debris, thereby protecting the light-emitting structure.
[0049] Furthermore, in one embodiment of this utility model, the lampshade includes a first patterned portion and a second patterned portion. A first light-emitting side 112 is disposed opposite to the first patterned portion, and a second light-emitting side 312 is disposed opposite to the second patterned portion. Both the first and second patterned portions are provided with multiple parallel stripe structures. These stripe structures cover the first main body 11 and the second main body 31, while allowing light to pass through. Specifically, the first and second patterned portions are integrally formed with the lamp housing, which is a transparent or semi-transparent component. Through this arrangement, the stripe structures of the first and second patterned portions can diffuse and guide light, making the light transmitted from the first light-emitting side 112 and the second light-emitting side 312 more uniform. In addition, the stripe structures can cover the first main body 11 and the second main body 31 inside the lampshade, preventing the internal structure from being directly exposed to the consumer's view, while not affecting light transmission. This not only improves the aesthetics of the lampshade but also prevents the presence of the first main body 11 and the second main body 31 from being directly observed by the consumer, thereby improving the overall aesthetics of the vehicle headlight.
[0050] This utility model also proposes a vehicle lamp, which includes a light-emitting structure. The specific structure of the light-emitting structure is as described in the above embodiments. Since this vehicle lamp 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, which will not be described in detail here.
[0051] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
