Description

Technical Field

[0001] This utility model relates to a vehicle light, and more specifically, to a vehicle light with a dazzling starry sky effect. Background Technology

[0002] With the rapid development of automotive intelligence and refined exterior design technologies, the functional and decorative attributes of automotive lights are continuously being upgraded. Headlights are no longer limited to basic functions such as traditional road lighting and light signal prompts; cool and diverse lighting effects are gradually becoming a core highlight of vehicle design and a mainstream industry trend. To achieve diverse lighting effects such as flowing dynamics, multi-color ambiance, and zoned illumination, existing headlight structures generally optimize the lighting display effect by adding light sources and lighting modules.

[0003] However, in practical applications, existing technologies have obvious technical defects. On the one hand, the increase in the number of light-emitting lamp groups and modules will directly lead to a significant increase in the overall structural volume and space occupied by the vehicle's light-emitting module. However, the space left for the installation cavity of the vehicle's lights is fixed and limited. Traditional large-volume light-emitting modules are difficult to adapt to the refined and integrated assembly requirements of vehicle lights, and are prone to assembly interference and low space utilization, which restricts the miniaturization and integration of vehicle lights.

[0004] On the other hand, when vehicle headlights are equipped with multiple light sources with different functions, the light from adjacent light sources is prone to mutual interference, easily causing undesirable light emission effects such as color temperature shift and uneven brightness. In summary, how to achieve a compact design of the light-emitting module while ensuring diverse light emission effects of vehicle headlights, and at the same time avoid the problem of mutual interference between multiple light sources, is a technical challenge that urgently needs to be solved in this field. Utility Model Content

[0005] This invention provides a vehicle headlight with a dazzling starry sky effect, which solves the problem that existing multi-source headlight modules are not compact enough and are prone to mutual light interference.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a vehicle headlight with a dazzling starry sky effect, comprising: The upper light-emitting module consists of a decorative frame, a reflective bracket, and a first light source. The decorative frame has an upper light-emitting surface. The first light source is located inside the area defined by the decorative frame and the reflective bracket. The decorative frame is light-transmitting and has a first textured surface on its inner surface. The reflective bracket is light-reflective and has a second textured surface on its inner surface. The middle-layer light-emitting module is composed of a first thick wall and a second light source, and the first thick wall is provided with a middle-layer light-emitting surface. The bottom light-emitting module consists of a second thick wall and a third light source, with a bottom light-emitting surface provided on the second thick wall; A first PCB board is located between the upper light-emitting module and the middle light-emitting module. The first light source is located on the upper surface of the first PCB board, and the second light source is located on the lower surface of the first PCB board. The first PCB board can separate the light emitted by the first light source and the light emitted by the second light source. A partition is disposed between the middle layer light-emitting module and the bottom layer light-emitting module and is itself opaque; The upper light-emitting module, the middle light-emitting module, and the bottom light-emitting module are stacked in a sandwich structure, with the upper light-emitting surface, the middle light-emitting surface, and the bottom light-emitting surface located on the same side.

[0007] Furthermore, the first thick wall is divided into an inner thick wall component and an outer thick wall component. The inner thick wall component is provided with a first light-incident part and a light-emitting surface. The second light source is directly opposite the first light-incident part. The outer thick wall component is provided with a second light-incident part. The second light-incident part is directly opposite the light-emitting surface and forms a gap. The middle layer light-emitting surface is located on the outer side of the outer thick wall component. The light-emitting surface is provided with continuous raised textures, and the second light-incident part is provided with continuous recessed textures.

[0008] Furthermore, the lower surface of the outer thick-walled component is provided with a third textured surface, and the outer thick-walled component protrudes from the upper light-emitting module and the lower light-emitting module, thereby exposing part of the third textured surface.

[0009] Furthermore, a cover plate extends from the outer thick-walled member and partially covers the upper surface of the inner thick-walled member. A positioning post is integrally formed on the upper surface of the inner thick-walled member, and the positioning post and the cover plate are interlocked for positioning.

[0010] Furthermore, the outer surface of the decorative frame is covered with a light-shielding layer, and the light-shielding layer is provided with irregular light-transmitting holes; light enters the decorative frame through the first textured surface and is emitted from the upper light-emitting surface through the irregular light-transmitting holes.

[0011] Furthermore, both the first and second textured surfaces have a diamond-like structure, and the surface of the second textured surface is also provided with a reflective coating.

[0012] Furthermore, the bottom light-emitting module also includes a second PCB board and a lower bracket. The lower bracket is located below the second thick wall, and the second PCB board is located between the second thick wall and the lower bracket. The third light source is disposed on the second PCB board, and the second thick wall is provided with a third light-incident part facing the third light source.

[0013] Furthermore, it also includes an inner cover and a light-transmitting outer cover. The upper light-emitting module, the middle light-emitting module, and the lower light-emitting module are located inside the cavity defined by the inner cover and the light-transmitting outer cover, and the upper light-emitting surface, the middle light-emitting surface, and the lower light-emitting surface face the side of the light-transmitting outer cover.

[0014] In summary, this utility model has the following beneficial effects: by integrating three light-emitting modules into one unit through a sandwich stacking structure, and with the first light source mounted on the first PCB board in a side-emitting direction, while the first light source and the second light source share the first PCB board, the overall space occupied by the multi-light source module is greatly reduced. While achieving the superposition of multiple layers of different light-emitting effects and presenting a rich and dazzling starry sky visual effect, it also meets the assembly requirements of vehicle lights integration and miniaturization.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Example: See Figure 1 , Figure 2 and Figure 4 A car headlight with a dazzling starry sky effect includes: an upper light-emitting module 100, which consists of a decorative frame 110, a reflector bracket 120, and a first light source 130. The decorative frame 110 has an upper light-emitting surface 140, and the first light source 130 is located inside the area defined by the decorative frame 110 and the reflector bracket 120. The decorative frame 110 is translucent and has a first textured surface 150 on its inner surface. The reflector bracket 120 is reflective and has a second textured surface 160 on its inner surface; a middle light-emitting module 200, which consists of a first thick wall 210 and a second light source 220. The first thick wall 210 has a middle light-emitting surface 230; and a lower light-emitting module 300, which consists of a second thick wall 310 and a third light source 320. The upper part has a bottom light-emitting surface 330; a first PCB board 400, which is located between the upper light-emitting module 100 and the middle light-emitting module 200, a first light source 130 is located on the upper surface of the first PCB board 400, and a second light source 220 is located on the lower surface of the first PCB board 400. The first PCB board 400 can separate the light emitted by the first light source 130 and the light emitted by the second light source 220; a partition 500, which is located between the middle light-emitting module 200 and the bottom light-emitting module 300 and is opaque itself; the upper light-emitting module 100, the middle light-emitting module 200 and the bottom light-emitting module 300 are stacked in a sandwich structure, and the upper light-emitting surface 140, the middle light-emitting surface 230 and the bottom light-emitting surface 330 are located on the same side.

[0019] For details, see Figure 2 The first light source 130 is mounted on the first PCB board 400 with a side-emitting orientation, facing the decorative frame 110 and the reflector bracket 120.

[0020] For details, see Figure 4 and Figure 5 The first thick wall 210 is divided into an inner thick wall component 240 and an outer thick wall component 250. The inner thick wall component 240 is provided with a first light-incident part 241 and a light-emitting surface 242. The second light source 220 is directly opposite the first light-incident part 241. The outer thick wall component 250 is provided with a second light-incident part 251. The second light-incident part 251 is directly opposite the light-emitting surface 242 and forms a gap. The middle light-emitting surface 230 is located on the outer side of the outer thick wall component 250. The light-emitting surface 242 is provided with continuous raised textures, and the second light-incident part 251 is provided with continuous recessed textures.

[0021] For details, see Figure 4The continuous raised texture resembles a cornflake pattern, with each raised unit measuring 0.8 × 0.8 cm. The continuous recessed texture resembles a rhombus, with each recessed unit measuring 0.7 × 0.7 cm. The continuous raised texture increases the light refraction surface and achieves initial light diffusion. The continuous recessed texture serves as an optical optimization layer, with its inner surface designed at a 45° bevel. This angle is designed to avoid direct intersection with the continuous raised texture, thereby eliminating moiré interference that occurs when the two textures overlap.

[0022] For details, see Figure 4 The lower surface of the outer thick-walled component 250 is provided with a third textured surface 252, and the outer thick-walled component 250 protrudes from the upper light-emitting module 100 and the lower light-emitting module 300, thus exposing part of the third textured surface 252. The third textured surface 252 is an irregular geometric pattern, used to further disperse the light to increase the visual randomness and depth. This structure significantly enhances the three-dimensional layering of light and shadow while ensuring the purity of the starry sky light effect.

[0023] For details, see Figure 3 , Figure 4 The outer thick-walled member 250 extends with a cover plate 253 that partially covers the upper surface of the inner thick-walled member 240. The upper surface of the inner thick-walled member 240 is integrally formed with a positioning post 243, and the positioning post 243 and the cover plate 253 are inserted for positioning.

[0024] For details, see Figure 6 The outer surface of the decorative frame 110 is covered with a light-shielding layer, and the light-shielding layer is provided with irregular light-transmitting holes 111; the light enters the decorative frame 110 through the first textured surface 150 and is emitted from the upper light-emitting surface 140 through the irregular light-transmitting holes 111 to present a starlight effect.

[0025] For details, see Figure 6The outer surface of the decorative frame 110 is provided with a first UV layer 112, an aluminum plating layer 113, a PU layer 114, a second UV layer 115 and a sputtered chrome plating layer 116 from the inside out. The aluminum plating layer 113 constitutes the above-mentioned light-shielding layer. By performing a laser engraving process on the aluminum plating layer 113 and the PU layer 114 to process a specified light-transmitting pattern, the above-mentioned irregular light-transmitting hole 111 is formed. The first UV layer 112 increases the adhesion of the aluminum layer, ensuring it meets the adhesion requirements for the internal surface of the lamp. The aluminum plating layer 113 makes the decorative frame 110 opaque, and the aluminum layer is extremely thin. After subsequent laser engraving, the difference between the laser-engraved and non-laser-engraved surfaces is minimal, reducing the risk of appearance defects such as pits. The PU layer 114 is used to adjust the color of the product's appearance and increase the adhesion of subsequent surface treatments. The irregular light-transmitting holes 111 achieve various lighting pattern effects. The second UV layer 115 is used to fill the difference between the laser-engraved and non-laser-engraved surfaces after laser engraving, solving the static uneven appearance defects of the decorative frame 110. The sputtered chrome plating layer 116 is translucent, but still has a high-gloss metallic effect in the static non-lit state. That is, when the lamp is not lit, the decorative frame 110 presents a high-gloss aluminum plating effect, which can cover the internal laser-engraved patterns and internal structure. After being lit, the high-gloss area formed by the laser-engraved patterns can be seen through.

[0026] For details, see Figure 2 Both the first textured surface 150 and the second textured surface 160 have a diamond-like surface texture, and the surface of the second textured surface 160 is also coated with a reflective coating. The diamond-like surface texture consists of several randomly distributed polyhedral facets, with facet sizes ranging from approximately 5 to 20 mm. 2 The reflective coating material is aluminum or silver plating.

[0027] For details, see Figure 4 The bottom light-emitting module 300 also includes a second PCB board 600 and a lower bracket 700. The lower bracket 700 is located below the second thick wall 310, and the second PCB board 600 is located between the second thick wall 310 and the lower bracket 700. The third light source 320 is disposed on the second PCB board 600, and the second thick wall 310 is provided with a third light-incident part 311 that is directly opposite to the third light source 320.

[0028] For details, see Figure 1 It also includes an inner cover 800 and a light-transmitting outer cover 900. The upper light-emitting module 100, the middle light-emitting module 200 and the lower light-emitting module 300 are located inside the cavity defined by the inner cover 800 and the light-transmitting outer cover 900, and the upper light-emitting surface 140, the middle light-emitting surface 230 and the lower light-emitting surface 330 face the side of the light-transmitting outer cover 900.

[0029] A portion of the light emitted from the first light source 130 enters the decorative frame 110 directly through the first textured surface 150 and exits from the upper light-emitting surface 140. The first textured surface 150 can produce an irregular refraction effect on the light. A portion of the light emitted from the first light source 130 can also be reflected by the second textured surface 160 before returning to the first textured surface 150. At this point, this portion of light is superimposed on the irregular reflection effect of the second textured surface 160, ultimately causing the light emitted from the upper light-emitting surface 140 to produce a sparkling effect similar to crushed diamonds. Combined with the irregular light-transmitting hole 111 structure on the outer surface of the decorative frame 110, the upper light-emitting surface 140 can present a point-like starlight visual effect similar to a starry sky and galaxy. Simultaneously, the reflective coating on the first PCB board 400 and the second textured surface 160 completely isolates the light crosstalk between the first light source 130 and the second light source 220. The partition 500 also physically separates the light from the second light source 220 and the third light source 320, structurally preventing interference between light from different levels of light sources. The lower bracket 700 and the second PCB board 600 can also physically separate the light leaked from the third light source 320 and the second thick wall 310, thereby confining the light-emitting effect of the bottom light-emitting module 300 to one side of the bottom light-emitting surface 330.

[0030] The three light-emitting modules are integrated into one unit using a sandwich stacking structure. The first light source 130 is mounted on the first PCB board 400 with a side-emitting orientation. Simultaneously, the first light source 130 and the second light source 220 share the first PCB board 400, significantly reducing the overall space occupied by the multi-light source module. This achieves a multi-layered, multi-effect light emission, creating a rich and layered visual effect of a dazzling starry sky, while meeting the assembly requirements for integrated and miniaturized automotive lights. It also solves the problems of low space utilization and assembly interference inherent in traditional multi-light source automotive lights. The three-layer light-emitting structure can be individually controlled or combined for illumination, enabling various dynamic starry sky effects and adapting to different automotive light display needs in various scenarios.

[0031] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
