Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting design technology, specifically to an interactive vehicle lighting structure. Background Technology

[0002] As automobiles become increasingly electrified and intelligent, people's aesthetic standards for car lights are rising. Lighting patterns have evolved from traditional single-point illumination to multiple patterns and even animated displays, resulting in more innovative lighting modes and enhanced human-computer interaction. However, current interactive lights often use single-color thick-walled injection molding with a bracket for light blocking, or use a diffuser material sprayed with paint and laser engraving followed by a bracket for light blocking. These methods result in poor light blocking, significant light leakage between adjacent pixels, and poor visual perception at wide angles, failing to meet users' increasingly sophisticated aesthetic demands. Specifically, this includes the following two points:

[0003] 1. Existing technologies mostly adopt a transparent inner lampshade plus bracket solution, which results in bright spots when lit, unevenness, rapid brightness decay at wide viewing angles, and a small observation angle; or a diffuse inner lampshade sprayed with paint and then laser engraved solution, which results in more light leakage between adjacent pixels, unclear boundaries, and easy positional shift at wide viewing angles, poor visual perception, and high cost.

[0004] 2. Although the LED dot matrix screen with transparent inner light cover has a high pixel count, the center brightness is too high and can be dazzling, resulting in poor visual perception. In addition, it has high power consumption and high cost, making it unsuitable for ordinary car models.

[0005] In conclusion, how to improve the structure of vehicle lights to enhance the uniformity of interactive light illumination is a technical problem that needs to be solved. Utility Model Content

[0006] The problem to be solved is to improve the structure of the headlights to enhance the uniformity of the interactive lights and prevent light leakage between different windows.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an interactive vehicle lamp structure, including an optical module and an outer lamp cover. The optical module includes a circuit board and several LED light sources. The LED light sources are located between the circuit board and the outer lamp cover and are evenly distributed on the circuit board. The optical module is connected to a dual-color inner lamp cover through multiple light-blocking brackets. The dual-color inner lamp cover includes a regularly arranged light-transmitting part and a light-blocking part. One end of the light-blocking bracket is connected to the circuit board and located between adjacent LED light sources, and the other end of the light-blocking bracket is connected to the corresponding light-blocking part of the inner lamp cover. The side of the dual-color inner lamp cover facing away from the LED light sources is connected to the outer lamp cover. The light emitted by the LED light sources can pass sequentially through the gaps between the light-blocking brackets, the light-transmitting part of the inner lamp cover, and the outer lamp cover.

[0008] Preferably, a two-color decorative ring is provided between the inner and outer lampshades, the two-color decorative ring including a semi-transparent part and an opaque part.

[0009] Preferably, the semi-transparent part of the decorative ring is made of smoky gray transparent material with a transmittance of 10%-65%, while the opaque part of the decorative ring is made of black opaque material.

[0010] Preferably, the light-transmitting part of the inner lampshade is made of light-diffusing material, the thickness of the light-transmitting part of the inner lampshade does not exceed 3.5mm, and the light-blocking part of the inner lampshade is made of light-blocking material.

[0011] Preferably, the regular arrangement refers to a neat arrangement, an alternating arrangement, or a gradual arrangement.

[0012] Preferably, the connection between the light-transmitting part and the opaque part of the inner lampshade is flush, protruding, or concave.

[0013] Compared with the prior art, the present invention provides an interactive vehicle light structure, which has the following beneficial effects:

[0014] (1) The light-blocking bracket is set between the LED light sources and the light passes through the dual-color inner lamp cover before entering the outer lamp cover. The dual-color inner lamp cover includes the light-transmitting part of the inner lamp cover and the light-blocking part of the inner lamp cover. The structure solves the problems of uniformity of interactive lights and light leakage between windows. Compared with the existing ISD interactive lights, the lighting uniformity is improved. At the same time, light leakage between windows is avoided.

[0015] (2) The two-color decorative ring achieves the effect of hiding static internal features.

[0016] (3) It has a cost advantage compared to dot matrix screen solutions, achieving a balance between the large pixel size of traditional forms and the high cost of dot matrix screens. Attached Figure Description

[0024] The technical solutions of the present utility model will now be described with reference to the accompanying drawings in the embodiments of the present utility model:

[0025] To address the problems mentioned in the background art, this utility model proposes an interactive vehicle light structure, such as... Figure 1 The diagram shown is a cross-sectional view of this utility model. The key structure of this interactive lamp includes an optical module 1, a light-blocking bracket 4, a dual-color inner lampshade 5, a dual-color decorative ring 8, and a transparent outer lampshade 11. The optical module 1 includes a circuit board 2 and several LED light sources 3. The LED light sources 3 are located between the circuit board 2 and the outer lampshade 11 and are evenly distributed on the circuit board 2. The circuit board 2 can be a rigid board, multiple rigid boards spliced ​​together, or a flexible circuit board. The optical module 1 is connected to the dual-color inner lampshade 5 through multiple light-blocking brackets 4. The dual-color inner lampshade 5 includes regularly arranged light-transmitting portions 6 and opaque portions 7. Part 7 refers to the light-transmitting part 6 and the opaque part 7 of the inner lampshade, which can be arranged neatly, staggered, or in a gradient arrangement; the dual-color inner lampshade 5 is made by dual-color injection molding process and is composed of the light-transmitting part 6 and the opaque part 7 of the inner lampshade. The light-transmitting part 6 of the inner lampshade is a light-diffusing material, and the opaque part 7 of the inner lampshade is an opaque material. The light outlet of the light-transmitting part 6 of the inner lampshade constitutes a pixel. The connection between the light-transmitting part 6 and the opaque part 7 of the inner lampshade is flush, convex, or concave.

[0026] One end of the light-blocking bracket 4 is connected to the circuit board 2 and located between adjacent LED light sources 3. The other end of the light-blocking bracket 4 is connected to the corresponding opaque part 7 of the inner lamp cover. The side of the dual-color inner lamp cover 5 facing away from the LED light source 3 is connected to the outer lamp cover 11. The light emitted by the LED light source 3 can pass through the gap between the light-blocking brackets 4, the light-transmitting part 6 of the inner lamp cover, and the outer lamp cover 11 in sequence.

[0027] A two-color decorative ring 8 is provided between the inner lampshade 5 and the outer lampshade 11. The two-color decorative ring 8 includes a semi-transparent portion 9 and an opaque portion 10. The two-color decorative ring 8 is made by a two-color injection molding process. The semi-transparent portion 9 is made of a smoky gray transparent material, and the opaque portion 10 is made of a black opaque material. The black opaque material is used to cover areas that are not intended to be seen by the human eye, except for the pixel window. The semi-transparent portion 9 can completely cover the pixel window, i.e., the light-transmitting portion 6 of the inner lampshade. The semi-transparent portion 9 of the two-color decorative ring 8 uses a low transmittance or semi-transparent surface treatment to reduce the visibility of the internal features of the lamp in the off-light state, increasing the mystery of the lamp in the static state.

[0028] like Figure 2 The diagram shows the optical path of this invention. The incident light 12 emitted by the LED light source 3 enters the light-transmitting portion 6 of the inner lampshade through the light inlet between the light-blocking brackets 4, becoming transmitted light 13. After being uniformly distributed by the light-transmitting portion 6, it is constrained by the light-exiting opening of the inner lampshade 6, forming an outgoing light 14. This outgoing light then enters the semi-transparent portion 9 of the decorative ring, becoming an outgoing light 15, which enters the outer lampshade 11, finally forming the illumination light 16 visible to the human eye. Furthermore, when the vehicle and lights are in a static state, i.e., when the pixel window is not lit, the human eye sees the semi-transparent portion 9 of the dual-color decorative ring 8 through the transparent outer lampshade, visually creating a mirror-like smoky gray appearance, adding a sense of mystery and atmosphere to the vehicle and lights.

[0029] Figure 3 This is a partial front view of the dual-color inner lampshade. Figure 4 Partial rear view of the dual-color inner lampshade. Figure 5 for Figure 3 AA, BB Figure 4 Cross-sectional view at CC section. Figure 6 Axial view of the light-transmitting part of the inner lampshade. The light-transmitting part 6 of the inner lampshade is made of light-diffusing material, and the opaque part 7 of the inner lampshade is made of opaque material. The dual-color inner lampshade 5 is injection molded from light-diffusing material and opaque material in two colors. The light-diffusing material is made of... Figure 6 The structure uses opaque material to divide the light-diffusing material on the top, bottom, left, and right sides, thus preventing light leakage and meeting the requirements of mold injection molding.

[0030] like Figure 1 , 2As shown, visual color effects can also be achieved by changing the color of the smoky gray transparent material. Considering cost advantages, the transparent outer lampshade 11 can be directly combined with the dual-color decorative ring 8. The outer lampshade 11 is made of a dual-color injection molded material of smoky gray transparent material and black opaque material. The black opaque material is used to cover areas that are not desired to be seen by the human eye, except for the pixel window. The light-blocking bracket 4 is made of materials with relatively low hardness, such as PP. The front width of the opaque part 7 of the inner lampshade is about 2mm-3mm, the transmittance of the semi-transparent part 9 of the decorative ring is about 10%-65%, and the thickest part of the light-transmitting part 6 of the inner lampshade is 3.5mm. Each light-emitting unit of the light-transmitting part 6 of the inner lampshade can be square, rounded rectangle, circle, polygon, etc.; the size of each light-emitting unit of the light-transmitting part 6 of the inner lampshade can be uniform or regularly varied.

[0031] This invention utilizes a dual-color inner lampshade 5 and a light-blocking bracket 4 to block light, preventing light leakage between adjacent pixels and unclear pattern boundaries. The dual-color inner lampshade 5 employs a dual-color injection molding process. The light-transmitting portion 6 of the inner lampshade enhances optical uniformity, while the opaque portion 7 participates in light blocking. The edges of the pixel windows are defined by the opaque portion 7 of the inner lampshade, eliminating the need for additional pixel boundary structures. Furthermore, the dual-color inner lampshade 5 achieves equal-height dual-color splicing, avoiding secondary processing such as spraying or coating with black paint or other light-blocking materials on the outer surface of the inner lampshade. The connection between the light-transmitting portion 6 and the opaque portion 7 of the inner lampshade 5 can be varied, such as flush, protruding, or recessed, and can also be made into three-dimensional shapes, such as pyramids or polyhedral bosses.

[0032] The above embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
