Description

Technical Field

[0001] This invention relates to the field of automotive lighting technology, and in particular to a vehicle light with a starry sky and star chain light effect. Background Technology

[0002] With the rapid development of the automotive industry, LEDs have been increasingly used in vehicle lighting in recent years. To meet customer needs, vehicle lighting designs are no longer monotonous; while the shapes of vehicle lights have become more diverse, there is a greater pursuit of aesthetics, style, and unique lighting effects, and vehicle lights are gradually becoming more intelligent.

[0003] Currently, most starry sky concept car lights on the market use similar designs and processes, resulting in largely similar effects. The 3D starry sky and star chain effect is not very obvious, and the optical component structure is relatively complex, which is not conducive to the internal arrangement of the car light. For example, patent CN120062573A discloses a car light with a dazzling starry sky effect, including: a PCB board with a light source mounted on it; a reflector with a first patterned area; and a transparent inner mirror with one end connected to the reflector and a second patterned area on the side of the inner mirror near the reflector. The light source is positioned corresponding to the reflector and the transparent inner mirror. The light from the light source can be reflected by the first patterned area, pass through the second patterned area, and exit from the transparent inner mirror; or the light can pass directly through the second patterned area and exit from the transparent inner mirror. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a vehicle headlight with a starry sky and star chain light effect. Its 3D starry sky and star chain effect is obvious, and the optical components occupy little space, which is conducive to layout and installation.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: The vehicle headlight with starry sky and star chain light effect includes a headlight housing and a light source assembly and an inner mirror assembly disposed within the headlight housing. The inner mirror assembly includes an outer inner mirror and an inner inner mirror arranged side by side. The inner inner mirror is located between the outer inner mirror and the light source assembly. Both the outer inner mirror and the inner inner mirror are provided with a light-transmitting mirror reflective layer. The inner surface of the inner inner mirror is provided with an opaque coating, and the opaque coating is provided with a light effect hollow pattern for light to pass through.

[0006] Further or preferred: The headlight housing has a headlight decorative frame, and the light source assembly, inner inner mirror, and outer inner mirror are fixed in the headlight decorative frame from back to front.

[0007] A thick-walled component is provided between the light source assembly and the inner inner lens, and a diamond-patterned structure is provided on the outer surface of the thick-walled component; the light effect hollow pattern is a starry sky star chain hollow pattern or a nebula hollow pattern.

[0008] The outer inner lens includes an outer lens body and an outer lens mirror reflective layer composited on one side of the outer lens body.

[0009] The outer lens body is a transparent PC or PMMA plate with a thickness ranging from 1.8mm to 10mm. The outer lens mirror reflective layer is an indium-plated or nickel-plated layer formed by magnetron sputtering.

[0010] The inner lens includes an inner lens body, an inner lens reflective layer, and an opaque coating, with the inner lens reflective layer located between the inner lens body and the opaque coating.

[0011] The inner lens body is a transparent PC or PMMA plate with a thickness ranging from 1.8mm to 10mm. The inner lens mirror reflective layer is an indium-plated or nickel-plated layer formed by magnetron sputtering.

[0012] The opaque coating is a black coating sprayed with black paint, and the starry sky and star chain hollow pattern is a light-transmitting pattern area formed by laser engraving.

[0013] The light transmittance of both the outer and inner mirror reflective layers is 10%-15%.

[0014] Compared with the prior art, the present invention has the following advantages: The headlight structure with starry sky and star chain light effect is reasonably designed. It achieves a 3D starry sky effect through multi-layer superposition technology combined with magnetron sputtering and laser engraving processes, which has a great sense of technology and luxury. The inner and outer inner mirrors are both transparent and form a double mirror refraction space, which makes the 3D starry sky and star chain effect obvious. The inner and outer inner mirrors are set side by side, and the optical components occupy little space, which is conducive to layout and installation. Attached Figure Description

Detailed Implementation

[0023] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0024] Although the invention has been shown and described herein with reference to specific embodiments, it is not intended to be limited to the details shown. Rather, various modifications in detail may be made within the equivalent scope and scope of the claims without departing from the invention. In the drawings, the same item numbers refer to the same elements.

[0026] In this specification, relative terms such as “horizontal,” “vertical,” “upward,” “downward,” “top,” and “bottom,” and their derivatives (e.g., “horizontal,” “downward,” “upward,” etc.) should be interpreted as referring to the direction described or the direction shown in the accompanying drawings. These relative terms are for ease of description and are not generally intended to require a specific direction.

[0027] like Figures 1 to 7 As shown, the car headlight with starry sky and star chain light effect is a signal light or ambient light with a 3D starry sky and star chain effect; it uses multi-layer superposition technology to realize the 3D stereoscopic effect of the concept of the universe and star chain, simulating a real starry sky scene.

[0028] This vehicle light includes a headlight housing and a light source assembly 1 and an inner mirror assembly disposed within the headlight housing; the inner mirror assembly includes an outer inner mirror 3 and an inner inner mirror 4 arranged side by side, with a certain gap between the outer inner mirror and the inner inner mirror, and the inner inner mirror is located between the outer inner mirror and the light source assembly. Both the outer and inner inner mirrors are provided with a light-transmitting mirror reflective layer, and the inner surface of the inner inner mirror is provided with an opaque coating. The opaque coating has a light-effect hollow pattern for light to pass through; preferably, the light-effect hollow pattern is a starry sky and star chain hollow pattern 4031; if it is changed to a nebula pattern, it is also within the scope of protection of this patent. The inner and outer inner mirrors are both light-transmitting and form a double mirror refraction space, resulting in a significant 3D starry sky and star chain effect. The inner and outer inner mirrors are arranged side by side, with the optical components occupying little space, which is conducive to layout and installation.

[0029] The headlight housing has a headlight decorative frame 5. The light source assembly, inner inner mirror, and outer inner mirror are fixed in the headlight decorative frame from back to front. The headlight can be fixed by a bracket or directly in the headlight decorative frame. The inner inner mirror and the outer inner mirror are fixed by snap-fit ​​installation. The integrated design is compact.

[0030] A thick-walled component 2 is provided between the light source assembly and the inner inner lens. The outer surface of the thick-walled component is provided with a diamond-patterned structure 201. The thick-walled component, the inner inner lens, and the outer inner lens are integrated and fixed on the same fixed bracket to form a modular structure with a compact structure.

[0031] The thick-walled component 2 consists of a thin-walled and a thick-walled plate. The thick-walled component, the inner inner mirror, and the outer inner mirror are arranged side by side in sequence, occupying little space and facilitating the arrangement inside the headlights. The overall surface of the thin-walled and thick-walled components is a free-form surface with a matrix of disordered "crushed diamond" patterns designed on the surface to form diffuse reflection. When lit, it simulates the effect of the Milky Way in the universe. Combined with the double mirror reflection, it ultimately achieves a dazzling 3D light effect.

[0032] like Figure 5 As shown, the outer inner lens 3 includes an outer lens body 301 and an outer lens mirror reflective layer 302 composited on one side of the outer lens body; the outer lens body is a transparent PC or PMMA plate, the thickness of the outer lens body is 1.8mm-10mm, and the outer lens mirror reflective layer is an indium-plated layer or a nickel-plated layer formed by magnetron sputtering.

[0033] The outer lens reflective layer is located on the inner surface of the outer lens body; specifically, the inner surface of the outer lens is coated with a magnetron sputtering (PVD) process, and the coating has a gunmetal gray aluminum plating effect, which has light transmission and mirror reflection effects.

[0034] like Figure 6As shown, the inner inner lens 4 includes an inner lens body 401, an inner lens mirror reflective layer 402, and an opaque coating 403. The inner lens mirror reflective layer is located between the inner lens body and the opaque coating; that is, the inner lens body is located on the outside of the inner inner lens, and the opaque coating is located on the inside of the inner inner lens, with the opaque coating facing the light source assembly.

[0035] The inner lens body is made of transparent PC or PMMA sheet, with a thickness ranging from 1.8mm to 10mm. The reflective layer of the inner lens is an indium-plated or nickel-plated layer formed by magnetron sputtering. The opaque coating is a black coating sprayed with black paint, and the starry sky and star chain hollow pattern is a light-transmitting pattern area formed by laser engraving.

[0036] Specifically, the inner surface of the inner lens is sequentially coated with magnetron sputtering and black paint to form a double layer. The desired design pattern is then engraved using laser engraving. The magnetron sputtering layer and the black paint layer are retained outside the pattern. The magnetron sputtering inner lens reflective layer and the outer lens reflective layer together form a double mirror refraction space, which makes the design pattern form a 3D stereoscopic light effect.

[0037] The overall structural design adopts a double-layer internal fitting (PMMA material) thickened wall component plus a rear projection light source plate; through dual-color injection molding and design of physical structure, the thin and thick walls, inner and outer internal fitting lenses and light source components are integrated and fixed together, resulting in a stable and reliable structure.

[0038] Both the outer and inner mirror reflective layers have a light transmittance of 10%-15%. The light source assembly consists of a set of LED light sources mounted on the light source board. The light is emitted through a dazzling pattern, passing through laser-engraved holes to the double-mirror reflection space, and then emitted through the outer and inner mirrors. Multi-layer stacking technology, combined with magnetron sputtering and spray painting laser engraving processes, achieves a 3D starry sky effect.

[0039] Furthermore, the rear-projection light source was changed to a side-projection light source, or the diamond pattern was changed to other diffuse reflection patterns; the order relationship between the two inner mirrors and the special process treatment made both light transmission possible and a double-mirror refraction space formed between them; combined with the overall starry sky + star chain graphic combination and the 3D stereoscopic effect.

[0040] This invention provides a superior 3D starry sky and star chain light effect for automotive lighting. Through multi-layer stacking technology and a double-mirror refraction space formed by inner and outer mirrors, combined with a laser-engraved starry sky and star chain hollow pattern on the inner mirror, and the diffuse reflection effect of the diamond pattern on the thick-walled component, a realistic and dazzling 3D starry sky and star chain light effect can be achieved. The visual depth and atmosphere are outstanding, and the recognizability far exceeds that of conventional automotive lights. At the same time, the structural design is reasonable, with the inner and outer mirrors arranged side-by-side. Combined with the integrated design of the thin, thick-walled component, the space occupied by the optical components is significantly reduced, facilitating installation in the narrow area inside the headlight and adapting to the needs of various vehicle models.

[0041] In terms of assembly stability, the thick-walled parts, inner and outer mirrors, and light source components are integrated and fixed on the same bracket or headlight trim frame. They adopt integrated assembly methods such as snap-fit ​​and two-color injection molding to form a compact modular structure with stable connection and efficient assembly. In terms of process, the inner and outer mirrors are made of PC / PMMA transparent material. The mirror coating with both light transmission and reflection properties is formed by magnetron sputtering PVD process. The light transmittance is precisely controlled at 10%-15%. The opaque coating is laser engraved, with high pattern precision, regular light pattern, and stable and reliable optical performance.

[0042] In addition, the design is highly flexible, allowing for easy replacement of light source types (rear projection / side projection), adjustment of diffuse reflection patterns and starry sky and star chain patterns, adapting to the needs of different vehicle models and design styles. It combines functionality and aesthetics, serving as both a signal light or ambient light to meet the basic functions of vehicle lighting and signal indication, while also enhancing the vehicle's appearance and technological feel with its unique 3D starry sky and star chain light effect, achieving a perfect balance between practicality and aesthetics.

[0043] The above description is merely an illustration of preferred embodiments of the present invention, and the above technical features can be arbitrarily combined to form multiple embodiments of the present invention.
