Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, specifically to a light-emitting structure. Background Technology

[0002] To enhance the user experience, existing automotive headlights often incorporate special light-emitting structures beyond standard and regulatory compliance. These structures can achieve effects like a dazzling finish. For example, headlights with special lighting effects, such as the one disclosed in publication CN218845897U that uses a laser-engraved decorative ring to create a starry sky effect for daytime running / position lights, rely on a partially refracted LED light source passing through a specially patterned decorative ring. Because this effect is achieved through only partial light refraction, the actual lighting effect is not particularly dazzling. To provide sufficient light, a separate light source could be used instead of sharing a common light source with the headlight. However, in existing headlight structures, the light source, thick wall, and decorative ring are all aligned, resulting in a long light-emitting structure that affects the headlight layout. Furthermore, the number of LEDs increases with the area of ​​the light-emitting unit, leading to higher costs. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a light-emitting structure that can shorten the distance along the length direction and achieve a larger light-emitting area with fewer LED particles, thus saving on the number of LED particles and reducing costs.

[0004] The technical solution is as follows: a light-emitting structure includes a light source, a thick-walled component, a bracket, and a decorative ring with a light-transmitting pattern. Light emitted from the light source is directed through the thick-walled component to the decorative ring. The bracket is used to connect the light source, the thick-walled component, the decorative ring, and the vehicle headlight. The thick-walled component has a diamond-patterned refractive surface, which is formed by multiple polyhedral protrusions protruding from the thick-walled component. The thick-walled component extends at an angle, positioning the diamond-patterned refractive surface on the path of the light from the light source. The decorative ring is positioned relative to the diamond-patterned refractive surface to allow light refracted by the diamond-patterned refractive surface to be emitted through the light-transmitting pattern on the decorative ring.

[0005] Furthermore, the thick-walled component is curved.

[0006] Furthermore, the translucent pattern is composed of holes of varying sizes.

[0007] Beneficial effects: By using thick-walled components with diamond-patterned refractive surfaces, light is refracted and its direction is changed before it is emitted. At the same time, the decorative ring is located on the path of the refracted light. Compared with the existing arrangement of the same straight line, this solution can shorten the distance in length, making the spatial arrangement more reasonable. In addition, because the refraction is achieved by the multi-faceted protrusions protruding from the thick-walled components, the different emission directions of each refractive surface achieve a flashing effect with some surfaces being bright in each direction, thereby achieving a larger area of ​​light emission effect, which can save the number of LED chips and reduce costs.

[0012] like Figure 1 The illustrated light-emitting structure includes a light source 1, a thick-walled component 2, a bracket 3, and a decorative ring 4 with a translucent pattern. Light emitted from the light source 1 passes through the thick-walled component 2, which is made of transparent plastic, and is directed onto the decorative ring 4. The bracket 3 connects the light source 1, the thick-walled component 2, and the decorative ring 4 to the vehicle headlights (e.g., via screws). The light source 1 is independent of the main headlight light source and is specifically designed to produce special lighting effects, such as... Figure 3 The thick-walled component 2 shown has a diamond-patterned refractive surface 2-1. The diamond-patterned refractive surface 2-1 is formed by multiple polyhedral protrusions protruding from the thick-walled component 2. The thick-walled component 2 extends at an angle and positions the diamond-patterned refractive surface 2-1 on most or all of the light path of the light source 1. The decorative ring 4 is set relative to the diamond-patterned refractive surface 2-1 to allow the light refracted by the diamond-patterned refractive surface 2-1 to be emitted through the light-transmitting pattern on the decorative ring 4. The decorative ring 4 can be made of smoke-gray light-transmitting plastic, and its back can be first painted and then laser-engraved with circular starry sky holes of different sizes. The laser-engraved pattern is arranged in a diffused pattern.

[0013] Light source 1 can be an LED light source, combined with Figure 2As shown, the direct light is refracted by the diamond-patterned refractive surface 2-1, and then passes through the decorative ring 4 to achieve a dazzling effect. The diamond pattern size is between 1-4mm, and each pattern is a polyhedron. By having different emission directions for each refractive surface, a bright flashing effect is achieved in all directions, resulting in a large area of ​​light emission with fewer LEDs. This saves on the number of LEDs and, while achieving the same dazzling effect, the light-emitting structure saves space in the length direction. Moreover, the number of LEDs is far less than in a direct-projection, direct-emission scheme, saving on the cost per lamp.

[0014] Furthermore, the thick-walled component 2 is curved, further reducing the space along its length. The translucent pattern is as follows... Figure 4 The device consists of holes of varying sizes, 4-1. Light passes through the semi-transparent decorative ring, and the brightness and darkness of the light vary in different areas. Even in the same area, the brightness and darkness vary from different angles, thus achieving a dazzling effect.

[0015] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
