Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to an interactive light-emitting grille structure for vehicles. Background Technology

[0002] In modern lighting design, the front grille, as a crucial component of the car's front fascia, has seen a surge in innovative grille light designs, with interactive luminous grilles being the most prominent example of recent rapid development. However, traditional intelligent interactive grille lights, in order to address issues of light leakage and visible bright spots, typically require long, deep light-blocking brackets. This results in excessive space consumption and a thicker structure, failing to meet the increasingly sophisticated demands of end-users. It also increases component costs and presents challenges in assembly and window matching. Furthermore, as grille lights evolve towards flatter designs and more diverse interactions, the limited color options and variability of existing interactive lights pose a significant problem. When designing interactive lights with a large number of LEDs, traditional solutions, due to space constraints, cannot resolve light leakage and bright spot issues across all locations. Therefore, designing an interactive grille light that is structurally simple, cost-effective, innovative in effect, and provides uniform and stable illumination has become a pressing issue. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an interactive light-emitting grille structure for vehicles. It simplifies the number of lamp components in a limited space, reduces costs, not only occupies little space, but also ensures uniform and stable lighting effect.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] An interactive light-emitting grille structure for vehicles includes LED modules arranged inside and outside and an outer lamp cover, wherein multiple LED light sources are evenly distributed on the surface of the LED modules;

[0006] The outer lampshade includes an opaque main body and multiple light-transmitting windows spaced apart on the opaque main body, each light-transmitting window corresponding to an LED light source.

[0007] The light-transmitting window has a light-incident surface on the side closer to the LED light source and a light-exiting surface on the side farther from the LED light source. The width of the light-transmitting window gradually increases along the direction from the light-exiting surface to the light-incident surface.

[0008] The inner side of the outer lamp cover, except for the light-receiving surface, is provided with a light-shielding layer.

[0009] Furthermore, the light-incident surface is shaped into a concentrator structure, and the concentrator has a composite curved surface or parabolic surface structure.

[0010] Furthermore, the surface of the concentrator has optical patterns or textures.

[0011] Furthermore, the LED light source is a monochrome or RGB light source.

[0012] Furthermore, the light transmittance of the light-transmitting window is 20%-80%.

[0013] Furthermore, the outer lampshade is made of two colors by injection molding, with the first color being an opaque main body and the second color being a light-transmitting window.

[0014] Furthermore, the first color is the body color or black paint.

[0015] Furthermore, the second color is either colorless and transparent or colored and semi-transparent.

[0016] Furthermore, the light-shielding layer is aluminum-plated or painted.

[0017] Furthermore, the light-emitting surface is higher than the surface of the opaque main body, and a diffusion pattern is formed on the light-emitting surface.

[0018] By adopting the above technical solution, this utility model has the following beneficial effects:

[0019] 1. This utility model constructs an outer lampshade by injection molding it in two colors into an opaque main body and multiple light-transmitting windows spaced apart. A light-shielding layer is set on the inner side of the outer lampshade except for the light-incident surface. At the same time, the width of the light-transmitting windows gradually increases along the direction from the light-emitting surface to the light-incident surface. This can solve the problems of light leakage and direct bright spots when multiple LED light sources are emitting light. The structure of the outer lampshade is optimized and simplified, and internal light-blocking brackets and other components are omitted, which can meet the requirements of OEMs for cost reduction and efficiency improvement in modern lighting design.

[0020] 2. Based on solving the problems of light leakage and bright spots, this utility model simplifies the number of lamp components in a limited space, reduces costs, not only occupies little space, but also ensures uniform and stable lighting effect through the use of a concentrator and light-emitting surface patterns.

[0021] 3. This utility model has a simple structure, fewer parts, and is more convenient and quick to assemble; it is geared towards the requirements of flattened and diversified shapes of car lights, and the thickness can be made smaller, making it easier to meet the exquisite needs of customers.

[0022] 4. By simplifying or improving the light-blocking structure and the outer lampshade construction, this utility model allows for a larger space, which facilitates the development of interactive lighting optical schemes for a greater number of LED types, thereby meeting the diverse and dynamic needs of interactive light colors and achieving interactive grid light effects with various patterns and colors.

[0026] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0027] like Figure 1 , 2 As shown, in this embodiment, an interactive light-emitting grille structure for vehicles is provided, which mainly consists of an outer lampshade 1 and an inner LED module 2. The LED module 2 has multiple LED light sources 20 evenly distributed on its surface. The outer lampshade 1 is composed of an opaque main body 11 and multiple light-transmitting windows 12 spaced apart on the opaque main body 11. The number of light-transmitting windows 12 is the same as the number of LED light sources 20, and their positions correspond one-to-one. For example... Figure 1 The layout is four rows and six columns.

[0028] Specifically, each light-transmitting window 12 has a light-incident surface 122 on the side closer to the LED light source 20, i.e., the inner side, and a light-emitting surface 121 on the side farther away from the LED light source 20, i.e., the outer side. The light-emitting surface 121 is higher than the outer surface of the opaque body 11, and a diffusion pattern is formed on the light-emitting surface 121. On the one hand, this avoids the problem of the LED being visible when it is not lit in a static appearance, and on the other hand, it improves the uniformity of lighting and weakens the problem of direct bright spots.

[0029] To perfectly solve the problems of light leakage and direct bright spots, in this embodiment, the width of each light-transmitting window 12 gradually increases along the direction from the light-emitting surface 121 to the light-incident surface 122. Furthermore, a light-shielding layer 3 is provided on the inner side of the outer lampshade 1, excluding the light-incident surface 122. The light-shielding layer 3 can be aluminum-plated or painted, effectively achieving the division of illuminated areas and a clear sense of boundary. Thus, based on the simple and thin structure of this embodiment, it can achieve a good light-blocking effect without the aid of other components, solving the problems of light leakage and direct bright spots when multiple LED light sources are emitting light. The outer lampshade structure is optimized and simplified, omitting internal light-blocking brackets and other components, meeting the cost-saving and efficiency-enhancing requirements of modern lighting design OEMs. At the same time, while solving the problems of light leakage and bright spots, this embodiment simplifies the number of lighting components within a limited space, reducing costs. It not only occupies less space but also makes assembly more convenient and faster. It also caters to the requirements of flattened and diversified automotive headlight designs, allowing for a thinner profile and better meeting the refined needs of customers.

[0030] To improve the uniformity of illumination, the light-incident surface 122 in this embodiment is shaped into a light-concentrating structure. The light-concentrating structure can be a composite curved surface or a parabolic surface. The surface of the light-concentrating surface can be provided with optical patterns or textures to diffuse the light. The light-concentrating surface focuses the light emitted by the LED light source 20 into parallel light and emits it from the light-exiting surface 121.

[0031] It is worth mentioning that the outer lamp cover 1 in this embodiment is made by dual-color injection molding. The first color is the opaque main body 11, and the second color is the light-transmitting window 12. In actual manufacturing, the first color opaque main body 11 is painted in the body color or black; the second color light-transmitting window 12 is either colorless and transparent or colored and semi-transparent. The colored and semi-transparent window can be red, blue, green, gray, etc., and the light transmittance can be selected from 20% to 80%. When the second color light-transmitting window 12 is colorless and transparent, the condenser can be set with special optical patterns on its surface; when the second color light-transmitting window 12 is colored and semi-transparent, the condenser can also be designed with a smooth surface.

[0032] Furthermore, the LED light source 20 in this embodiment can be a monochrome or RGB light source. The array light source on the LED module 2 can be dynamically partitioned and illuminated in multiple colors through hardware and software design, forming various patterns and animation effects, and achieving multi-functional interaction with pedestrians. In summary, by simplifying or improving the light-blocking structure and the outer lampshade construction, more space is reserved to facilitate the development of interactive lighting optical schemes for a greater number of LED types, thereby meeting the diverse and dynamic needs of interactive light colors and achieving interactive grid light effects with diverse patterns and colors.
