Description

Technical Field

[0001] This utility model belongs to the field of automotive lighting technology, and more specifically, relates to an automotive lighting fixture with a lighting function. Background Technology

[0002] Automotive lighting has undergone continuous technological innovation, resulting in increasingly diverse designs. The demands for lighting effects are also constantly rising. Currently, there are many common light-emitting methods, such as LED direct-projection reflectors, side-projection reflectors, direct-projection thick-walled components, side-projection thick-walled components, light guide plates, light guide strips, and atomized internal components. These methods can also be combined. Although there are many light-emitting methods, the resulting effect is relatively singular. A single emitting surface can only produce one lighting effect. A single lighting pattern greatly limits the design possibilities. With the development of the automotive industry, existing optical solutions are increasingly unable to meet the demands of diverse designs. Technological breakthroughs are needed to flexibly arrange optical components within limited space to achieve diverse lighting effects.

[0003] Existing technology includes a technology entitled "A Light-Emitting Structure for Automotive Lamps and an Automobile," with publication number CN114017740B. This technology provides a light-emitting structure for automotive lamps and an automobile. The light-emitting structure includes an LED light source board, a light guide plate, a mounting bracket, a decorative ring, and a housing. The mounting bracket is disposed within the housing, and the LED light source board, light guide plate, and decorative ring are fixedly disposed on the mounting bracket. The LED light source board is disposed on one side of the light guide plate, and the decorative ring is disposed on the outer side of the light guide plate. A laser-engraved light-emitting structure is formed on the surface of the decorative ring. The point light source emitted by the LED light source board can be diffused through the light guide plate to form a uniform surface light source, and the surface light source can then pass through the laser-engraved light-emitting structure to form a corresponding light-emitting pattern. The technical solution provided by this invention can make the appearance pattern of automotive lamps sharper and more striking, and can ensure that the lighting effect of the pattern is uniform and consistent, leaving more design space and flexibility for the overall design of vehicle lamps. At the same time, it has certain advantages when the automotive lamp design is relatively dense and the edges are sharp. However, this technology does not involve the technical problems and technical solutions of this application. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an automotive lamp with lighting function that is simple in structure, can present different lighting patterns on the same light-emitting surface without interference between the patterns, can be lit independently or in combination, and can flexibly arrange optical components in a limited space to achieve a variety of lighting effects.

[0008] A thick-walled component and a bottom light source module are disposed between the rear position of the light guide plate and the bracket.

[0009] A decorative frame is provided at the outer position of the opening of the bracket.

[0010] A top light source module is installed on the upper part of the bracket.

[0011] The bottom light source module is positioned so that the light source is aligned with one side of the thick-walled component.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] The automotive lamp with lighting function described in this utility model has the following structural design: a light guide plate made of transparent material is placed on a bracket. The inner surface of the light guide plate is coated with a black paint layer, and then laser engraving is performed on the black paint layer to form a laser-engraved pattern. A pattern is set on the outer surface of the light guide plate. A thick-walled component and a bottom light source module are placed between the light guide plate and the rear of the bracket.

[0026] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0027] As attached Figure 1 - Appendix Figure 7As shown, this utility model is an automotive lamp with a lighting function. A transparent light guide plate 2 is set on the bracket 1. The inner surface of the light guide plate 2 is coated with a black paint layer, and a laser-engraved pattern 3 is set on the black paint layer. The outer surface of the light guide plate 2 is decorated with a pattern 4. To address the shortcomings of the prior art, an improved technical solution is proposed. In the structural design, a transparent light guide plate 2 is set on the bracket 1. The inner surface of the light guide plate 2 is coated with a black paint layer, and then laser engraving is performed on the black paint layer to form a laser-engraved pattern 3. The outer surface of the light guide plate 2 is decorated with a pattern 4. A thick-walled component 6 and a bottom light source module 7 are set between the light guide plate 2 and the rear of the bracket 1. A top light source module 9 is set at the top of the bracket 1. The light sources of the bottom light source module 7 and the top light source module 9 can be activated separately or simultaneously for separate or combined lighting. Figure 1 This is an exploded view of the optical scheme of this utility model. Figure 2 This is a cross-sectional schematic diagram. The optical solution of this utility model mainly includes a decorative frame 8, a light guide plate 2, a thick-walled component 6, a bracket 1, a top light source module 9, and a bottom light source module 7. Different patterns are illuminated by the top light source module 9 and the bottom light source module 7 respectively, and when both are illuminated simultaneously, a combined pattern is achieved. This allows for both single-point illumination (light emission) and combined illumination of both light-emitting surfaces. The overall solution is simple to install and disassemble, low in cost, and meets optical requirements. The automotive lamp with illumination function described in this utility model has a simple structure, enabling different illumination patterns to appear on the same light-emitting surface without interference. The patterns can be illuminated independently or in combination, allowing for flexible arrangement of optical components in a limited space to achieve diverse illumination effects.

[0028] The light guide plate 2 is positioned at the front of the opening 5 in the bracket 1. A thick-walled component 6 and a bottom light source module 7 are disposed between the light guide plate 2 and the rear of the bracket 1. In this structure, the light guide plate 2 serves to achieve two light emission patterns. The light guide plate 2 itself is transparent. Figure 3 For the cross-section illustration, the inner surface is sprayed with black paint, and then the light-emitting shape required for the design is engraved by laser. Figure 4 This is one specific embodiment, and the light-emitting shape required for the design can be selected according to different shapes as needed. Figure 4 The starry sky and mountain shapes are the first pattern in the specific embodiment. Simultaneously, optical patterns are added to the outer surface of the light guide plate; these optical patterns can be designed into different shapes according to the intended design. For example... Figure 5 Characteristics of an oblique meteor. Figure 5The oblique meteor feature is the second pattern in this specific embodiment. A direct-lighting thick-walled component and a bottom light source module are arranged at the bottom of the light guide plate. When the direct-lighting thick-walled component is lit, it can achieve the requirement of brilliant light emission, combined with the laser-engraved starry sky and mountain patterns. This will present a brilliantly illuminated starry sky and mountain lighting effect. Figure 6 The image shows the optical simulation effect when the thick-walled component is illuminated alone. It displays starry sky and mountain patterns. A top direct-light source module, equipped with a light source, is arranged on the top of the light guide plate 2. In this case, the light guide plate 2 will be used as a light guide plate. When the light source of the top light source module 9 is illuminated, the light guide patterns arranged on the outer surface of the light guide plate will be lit, forming an illuminated meteor pattern. (The image shows a simulated light source module 9.) Figure 7 This demonstrates the optical simulation effect when both top light source modules are lit simultaneously. Galaxy, mountains, and shooting star patterns are displayed concurrently.

[0029] A decorative frame 8 is provided on the outer part of the opening 5 of the bracket 1. In this structure, the decorative frame 8 is used to cover the light source and the internal mounting structure, preventing defects such as exposed mounting structure and stray light leakage from the lamp. The bracket 1 is used for mounting internal components and for blocking light between two light sources.

[0030] A top light source module 9 is installed on the upper part of the bracket 1. A light source 10 is installed on one side of the thick-walled component 6, aligned with the bottom light source module 7. A light source 10 is installed on one side of the bracket 1 and the light guide plate 2, aligned with the top light source module 9. Multiple light sources 10 are arranged at intervals from top to bottom in the bottom light source module 7. With the above structure, by controlling the current of the LED beads of the light source 10, the light source 10 of the bottom light source module 7 achieves brightness changes through a current reduction scheme, which can present dynamic effects such as starry sky, twinkling mountains and rivers, and breathing. The top light source module 9 can dynamically light up meteors by controlling the lighting sequence of the LED beads of the light source, making the meteors appear to move. The combination of the two optical schemes presents a beautiful effect of twinkling mountains and rivers and meteors streaking across the sky on the same emitting surface. Therefore, this utility model can achieve three lighting effects.

[0031] The pattern 4 on the outer surface of the light guide plate 2 consists of multiple dot-like structures, forming a meteor-shaped pattern 4. In this specific embodiment of the pattern design, the meteor pattern is presented on the front of the light guide plate 2, while the back of the light guide plate 2 is painted black. Therefore, when the bottom light source module 7 illuminates the galaxy and mountain patterns, the meteors are obscured and do not emit light. Similarly, when the top light source module 9 illuminates the meteor pattern, the light is emitted from the upper light guide pattern; in areas without patterns, light does not refract. Therefore, the laser-engraved pattern 3 is also not illuminated. This achieves the goal of allowing the two illuminated patterns on both sides of the light guide plate to be illuminated independently without affecting each other.

[0032] The automotive lighting fixture with illumination function described in this utility model is structurally designed as follows: a light guide plate 2 made of transparent material is placed on a bracket 1. A black paint layer is applied to the inner surface of the light guide plate 2, and then laser engraving is performed on the black paint layer to form a laser-engraved pattern 3. A pattern 4 is applied to the outer surface of the light guide plate 2. A thick-walled component 6 and a bottom light source module 7 are placed between the rear of the light guide plate 2 and the bracket 1. A top light source module 9 is placed on the upper part of the bracket 1. The light sources of the bottom light source module 7 and the top light source module 9 can be activated separately or simultaneously. Separate activation is used for single-point illumination, while simultaneous activation is used for combined illumination. Figure 1 This is an exploded view of the optical scheme of this utility model. Figure 2 This is a cross-sectional schematic diagram. The optical solution of this utility model mainly includes a decorative frame 8, a light guide plate 2, a thick-walled component 6, a bracket 1, a top light source module 9, and a bottom light source module 7. Different patterns are illuminated by the top light source module 9 and the bottom light source module 7 respectively, and when both are illuminated simultaneously, a combined pattern is achieved. This allows for both single-point illumination (light emission) and combined illumination of both light-emitting surfaces. The overall solution is simple to install and disassemble, low in cost, and meets the required optical performance.
