Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically to a car logo luminous structure with a metallic effect and an automotive light. Background Technology

[0002] As the emblem of an automaker, a car logo symbolizes its brand history, culture, and values; it also embodies emotions and represents artistic expression. To highlight styling advantages and brand power, logo design is receiving increasing attention from major automakers. How to present a car logo uniquely to end customers is one area of ​​interest for automakers.

[0003] Many car brand logos were designed with the characteristics of their era in mind. However, as times change and target audiences evolve, car logos need to be optimized and upgraded to cater to new users and potential consumers. Currently, most car logos on the market serve only as a car emblem and exterior decoration, with relatively limited functionality. If car logos could be illuminated and given signal light functions, or even further, if interactive features between people and logo lights could be achieved through programmed control (such as logo lights participating in welcoming and farewell functions), it would significantly enhance the technological and luxurious feel of the entire vehicle.

[0004] Research revealed that most existing illuminated logo lights on the market, as well as some publicly disclosed logo light patents, use LED light sources to directly illuminate the outer surface of the lampshade. The logo's appearance is created by the difference between the luminous and non-luminous areas on the lampshade surface. This structure is generally simple, requires a large number of LEDs, and is therefore costly. Furthermore, this type of logo presentation is limited to flat character designs, resulting in a lack of prominence and recognizability when illuminated, and a lack of visual impact and sophistication. Utility Model Content

[0005] One of the objectives of this invention is to solve the aforementioned problems in the existing technology and provide a car emblem luminous structure with a metallic effect. This luminous structure includes a light source, a light-diffusing plate, and an inner lens. The inner lens and the light source are respectively fixed to the front and rear sides of the light-diffusing plate. A metallic coating is provided on one surface of the light-diffusing plate, and a light-shielding layer with a laser-engraved emblem pattern is provided on one surface of the inner lens. Light emitted from the light source passes through the emblem pattern on the light-diffusing plate and the inner lens and is emitted outwards, achieving a uniform emblem illumination effect. When the light source is not emitting light, external light shines on the surface of the inner lens and enters the lamp body through the translucent emblem pattern. This incident light is reflected back by the metallic coating on the surface of the light-diffusing plate, also achieving a metallic luminous effect on the emblem.

[0006] In the above scheme, the light source is specifically a circuit board with an LED array on its surface, the LED array facing the light-diffusing plate and the inner lens. The LED array can be arranged in various ways, such as in a multi-row, multi-column arrangement or in the shape of a logo pattern.

[0007] In the above scheme, a light-transmitting metallic coating, specifically an aluminum coating, is provided on the front side (light-emitting surface or outer surface) of the light-diffusing plate. The aluminum coating is relatively thin, allowing light emitted from the light source to pass through the light-diffusing plate and project outwards. Simultaneously, the aluminum coating reflects external light to achieve the metallic luminous effect of the logo. If the aluminum coating were placed on the back side (light-incident surface or inner surface) of the light-diffusing plate, its ability to reflect external light would be significantly reduced, resulting in a substantial decrease in the visual effect of the logo when the light is not illuminated.

[0008] In the above scheme, a light-shielding layer is provided on the front side (light-emitting surface or outer surface) of the inner lens, and a logo pattern is laser-engraved thereon. An opaque paint is sprayed onto the outer surface of the transparent inner lens to form a light-shielding layer, and laser engraving technology is used to remove part of the paint to form a light-transmitting logo pattern.

[0009] In the above solution, the car logo luminous structure also includes a bracket and a lamp housing. The light-diffusing plate and the light source are fixed on the front and rear sides of the bracket, respectively, and the resulting assembly is fixedly connected to the lamp housing and the inner lens.

[0010] The second objective of this invention is to provide an automotive lamp with the aforementioned light-emitting structure. This lamp can be used alone or integrated into a lamp fixture (such as a position light) for combined use, i.e., a logo-position combination lamp.

[0011] Compared with existing logo light products on the market, the car logo luminous structure and corresponding headlights provided by this utility model have advantages such as simple structure, low cost, easy assembly, and good visual effect. Whether actively illuminating the logo or passively reflecting external light to present a metallic effect, they are characterized by good appearance and high recognizability. More importantly, this headlight can adapt to logo patterns of different sizes and shapes, and can be used to develop a series of logo light products. Attached Figure Description

[0017] 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 implementations will fall within the protection scope of this utility model.

[0018] like Figure 1-4 As shown, this utility model provides an emblem light with a metallic effect, the overall shape of which is rectangular. In some other embodiments, the emblem light can also be designed in other shapes such as triangle, circle, or ellipse, which can be flexibly adjusted according to the requirements of the OEM.

[0019] This metallic-effect logo light mainly consists of a circuit board 1, a bracket 2, a light-diffusing plate 3, and an inner lens 4. The bracket 2 is the main assembly component. The circuit board 1 is fixed to the back of the bracket 2 with screws, etc. The light-diffusing plate 3 is fixed to the front of the bracket 2 with clips, etc. The inner lens 4 covers the light-diffusing plate 3 and is fixedly connected to the bracket 2 with clips, etc. The assembled logo light is sealed and fixed to the vehicle body or inside the automotive lighting system, thus completing the assembly of the entire light.

[0020] The circuit board 1 is square, and multiple LEDs 11 are soldered on its front side. These LEDs 11 are arranged in a certain way, such as M rows × N columns, triangles or crosses, etc., thus forming a light source array.

[0021] The bracket 2 is injection molded from opaque plastic (such as ABS) and is square in shape. A square through hole is provided in the middle of the bracket 2 to allow light to pass through. In some embodiments, connecting arms extend outward from each side of the bracket 2 to form connecting arms, which are provided with screw holes, slots, or buckles for fixing other components to the bracket 2.

[0022] The light-diffusing plate 3 is also square, and is injection molded from milky white light-diffusing PC material. The back of the light-diffusing plate 3 ( Figure 1 The left side of the light-diffusing plate 31 is the light-incident surface 31, which is not coated or plated. The entire front side of the light-diffusing plate 3 is coated with a translucent metal (such as aluminum) layer, forming the reflective surface 32 of the light-diffusing plate. By controlling the process, the thickness, light transmittance, or refractive index of the metal coating can be changed, so that it can transmit internal light while reflecting external light.

[0023] The inner lens 4 has a similar structure and shape to the light-diffusing plate 3, and it is injection molded from transparent plastic (such as PC, PMMA, etc.). The back of the inner lens 4 is the light-incident surface 41, which is not coated or plated. The front (outer surface) of the inner lens 4 is coated with light-shielding paint and laser-engraved with a light-transmitting logo pattern, forming the light-exiting surface 42 of the inner lens.

[0024] like Figure 3-4 As shown, when powered on, LED 11 on circuit board 1 emits light. The light passes sequentially through the light-incident surface 31 and the reflective surface 32 of the light-diffusing plate and is emulsified and scattered by them. The scattered light passes through the logo pattern on the light-incident surface 41 and the light-exit surface 42 of the inner lens and then shines outward, thus forming a unique logo lighting effect. When LED 11 is not lit (i.e., the logo light is not lit), external light shines on the surface of the inner lens, and some of the light enters the lamp body through the light-transmitting logo pattern and is reflected back by the metal plating on the surface of the light-diffusing plate, so that the logo pattern still has good visual appeal and recognizability even when the light source is not lit.

[0025] This logo light uses an optical lighting scheme of LED array + light diffuser + inner lens, which can achieve a unique metallic lighting effect. It not only has a strong logo recognition, but also provides uniform light emission without the bright spots of LEDs.

[0026] In addition to being integrated into the taillights as an emblem light, this headlight can also be used as a position light for certification, giving it more functions.
