Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically to an automotive light that addresses the visual defect of a logo not being illuminated in a layered manner. Background Technology

[0002] Integrated logo lighting assemblies are becoming increasingly common in automobiles, especially in taillights. These taillights typically employ two methods: one involves developing a special black paint + aluminum-plated film structure, which is then adhered to the back of a transparent outer lens, allowing light to pass through and create the logo lighting effect; the other method uses black paint and laser engraving to create a pattern on the back of the outer lens, then forms an aluminum-plated surface on another component (such as an emulsion inner lens), and finally assembling both to achieve the logo lighting effect.

[0003] Analysis shows that the first method suffers from high diaphragm costs and low yield rates, making it difficult to meet the requirements of low cost and large-scale mass production. In the second method, the outer lens and the emulsion inner lens will always have a certain gap during assembly, resulting in a difference in the layering of the logo pattern when viewed from different directions and angles. This makes it difficult to meet customers' ultimate requirements for appearance, does not conform to the current requirements for personalized, fashionable, and trendy car headlight designs, and cannot create a high-end effect for the vehicle model. Utility Model Content

[0004] The purpose of this invention is to solve the aforementioned problems in the existing technology and provide a vehicle headlight with a visual defect of non-layered logo illumination. The headlight includes an outer lens, a fixed bracket, and a PCBA (Printed Circuit Board Assembly). The outer lens and PCBA are respectively fixed to the front and rear sides of the fixed bracket. An opaque paint layer and a metal plating layer are provided on the outer lens. A logo-shaped light-transmitting area is laser-engraved on the opaque paint layer. The metal plating layer is attached to the surface of the opaque paint layer and fills the logo-shaped light-transmitting area, making it semi-transparent. At least one LED light source is provided on the PCBA. The light emitted by the LED light source passes through the semi-transparent logo-shaped area on the outer lens, achieving a uniform, non-layered logo illumination effect.

[0005] In the above scheme, at least one annular or square light-transmitting area is laser-engraved on the opaque paint layer, and the annular or square light-transmitting area is also filled with a metal coating and becomes semi-transparent.

[0006] Furthermore, the annular or square-shaped light-transmitting area surrounds the logo-shaped light-transmitting area.

[0007] In the above scheme, the opaque paint layer and the metal coating are both located on the back of the outer lens (i.e., on the inner surface close to the light source).

[0008] Furthermore, the metal coating is specifically an aluminum coating.

[0009] In the above solution, the headlight also includes an emulsion inner lens. The shape of the emulsion inner lens is similar to that of the outer lens, and it is fixed between the outer lens and the mounting bracket. The main function of the emulsion inner lens is to disperse the light emitted by the LED light source so that it passes through the outer lens and is emitted, achieving a uniform and non-layered LOGO pattern lighting effect.

[0010] In the above scheme, an LED light source array is provided on the side of the PCBA facing the external lens. The LED light source array is arranged in the shape of a logo, or in a cross pattern, or in a circular or elliptical pattern.

[0011] In the above scheme, the vehicle lights specifically refer to automobile taillights.

[0012] This utility model provides a vehicle headlight product with a solution for eliminating visual defects in layered logo illumination. It boasts advantages such as simple structure, easy assembly, low cost, high yield, and outstanding lighting effect. By employing a black paint shielding layer on the back of the outer lens and a partially translucent aluminum-coated film layer formed by laser engraving and vapor deposition, a uniform, layered logo illumination effect is achieved. Compared to the previous two solutions, this utility model's headlight eliminates visual differences and layers, ensuring that OEMs can customize logo shapes as needed and meeting their requirement for a seamless, layered logo illumination effect. It also allows for the creation of unique shapes and appearances, potentially leading to significant economic benefits. Attached Figure Description

[0016] To enable those skilled in the art to fully understand the technical solution and beneficial effects of this utility model, the following detailed description is provided in conjunction with specific embodiments and accompanying drawings. It should be emphasized that these embodiments and drawings are merely some implementations of this utility model. Besides these, this utility model can have many other implementations, and any simple improvements or substitutions based on these embodiments will fall within the protection scope of this utility model.

[0017] The taillights provided by this utility model address the visual defect of the logo not illuminating in a layered manner, such as... Figure 1-2 As shown, it mainly includes an outer lens, an emulsion inner lens 4, a fixing bracket 5, a PCBA 6, and a lamp housing. The fixing bracket 5 is the main assembly body, the emulsion inner lens 4 is fixed to the front of the fixing bracket 5, and the PCBA 6 is fixed to the back of the fixing bracket 5. The fixing bracket 5 is fixedly connected to the lamp housing, and the outer lens is sealed to the lamp housing. That is, the outer lens, the emulsion inner lens 4, the fixing bracket 5, the PCBA 6, and the lamp housing are arranged in a front-to-back stacked arrangement.

[0018] The manufacturing process begins with injection molding an outer lens from transparent engineering plastic (such as PC), referred to as transparent outer lens 1. Then, black paint is sprayed onto the back of transparent outer lens 1, resulting in outer lens 2 with a masking layer. Next, the masking layer undergoes laser engraving, removing black paint from specific areas according to the logo pattern provided by the OEM, obtaining a translucent logo and its surrounding translucent ring. Finally, an aluminum plating layer is deposited, covering the entire back of the outer lens. During this process, there are no concerns about unclear aluminum plating boundaries or junctions, resulting in laser-engraved aluminum-plated outer lens 3. These plating layers, while covering the black masking layer, also fill the laser-engraved translucent logo and its surrounding translucent ring, forming a semi-transparent translucent pattern with a plating layer (i.e., translucent area 7). After this treatment, whether viewed from the front or side, there will be no light leakage, no visibility of the headlight interior or aluminum plating, and no layered lighting of the logo.

[0019] The emulsion inner lens 4 is injection molded from transparent or semi-transparent engineering plastics (such as PC or PMMA). If necessary, optical reflection structures can be set on its inner or outer surface to enhance its light scattering ability. Connecting arms are provided on the left and right sides of the emulsion inner lens 4. Connecting holes are provided on the connecting arms. After the screw passes through the connecting holes, it is locked to the fixing bracket 5 and the lamp housing.

[0020] The mounting bracket 5 and the lamp housing are both injection molded from opaque engineering plastics (such as ABS). Matching connection holes or screw holes are provided on the left and right sides of the mounting bracket 5 and the lamp housing to facilitate fixed connection with the emulsion inner lens 4, PCBA 6, etc.

[0021] On the side of the PCBA 6 facing the outer lens, multiple LED beads are distributed in a distributed array, forming a light source. Each LED bead is connected to the vehicle's control switch and power supply via a wiring harness. The light emitted by the LED beads passes through the semi-transparent light-transmitting area on the emulsion inner lens 4 and the outer lens before being emitted outward, creating a specific logo lighting effect. The arrangement of the LED beads is related to the shape of the logo; they are usually arranged according to the shape of the logo pattern, but can also be arranged in a cross pattern, a circular or elliptical ring pattern, or a combination of these arrangements.

[0022] The assembled headlights are like Figure 1 As shown, the logo's translucent area is centered on the front, surrounded by one or two concentric elliptical translucent areas. When the LED light source array is powered on, it emits light. The light passes through the emulsion inner lens 4 and then scatters outwards. The scattered light passes through the translucent logo and the elliptical translucent areas on the outer lens before exiting. Because the aluminum-plated film layer and the black paint masking layer are on the same surface, without the gaps between parts or the thickness differences caused by the parts themselves, a seamless and uniform lighting effect for the logo pattern can be achieved.

[0023] In the taillight with logo illumination provided by this utility model, the black paint masking layer, the metal plating layer, and the logo pattern layer are all on the back of the outer lens. Therefore, there is no issue of layered illumination, and there is no difference in appearance, which fully meets the requirements of OEMs. More importantly, the logo illumination pattern can be customized at will, and it is relatively simple and low-cost to implement.
