Description
Technical Field
[0001] This utility model relates to the field of automotive parts, specifically providing an automotive daytime running light and an automotive component. Background Technology
[0002] With the rapid development of the automotive industry and the increasing demand from consumers for personalized vehicles, daytime running lights (DRLs) are becoming increasingly diverse in design. However, there are currently relatively few DRL products on the market that offer a starry sky effect, and those that do exist have significant technical limitations.
[0003] Existing starry sky effect headlights primarily rely on specific light sources and optical designs to create a captivating starry sky effect at night. However, during the day, due to strong sunlight, their brightness is often insufficient, making it difficult to achieve the ideal dynamic lighting effect. This not only limits the decorative and recognizable nature of daytime running lights but also fails to fully meet consumers' dual needs for aesthetics and practicality in headlights.
[0004] Therefore, developing a daytime running light that can both create a starry night effect and maintain high brightness and good visibility during the day has become a pressing technical problem in the field of automotive lighting design. Utility Model Content
[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the existing car daytime running lights lack the effect of presenting starry night sky and dynamic daytime light effects.
[0006] In a first aspect, the present invention provides a car daylight, including a housing and a light source disposed within the housing. A transparent lampshade is disposed at the front end of the housing. The car daylight also includes a first light-transmitting plate and a second light-transmitting plate disposed within the housing. The first light-transmitting plate and the second light-transmitting plate are arranged sequentially along the direction from the light source toward the lampshade. A first prism structure is disposed on the first light-transmitting plate, and a second prism structure is disposed on the second light-transmitting plate.
[0007] In the preferred embodiment of the above-mentioned vehicle daytime running light, the vehicle daytime running light further includes a first reflector disposed within the housing. The first reflector is disposed downstream of the first light-transmitting plate. The first reflector has a reflective surface. Light refracted by the first light-transmitting plate is reflected onto the reflective surface and then onto the second prism structure.
[0008] In the preferred embodiment of the above-mentioned vehicle daytime light, the first prism structure includes a plurality of first prism units, which are arranged in a regular or irregular manner on the first light-transmitting plate, and each first prism unit has a plurality of inclined surfaces.
[0009] In the preferred embodiment of the above-mentioned automotive daytime light, the second prism structure includes a plurality of second prism units, which are arranged in a regular or irregular manner on the second light-transmitting plate, and each second prism unit has a plurality of cut surfaces, each of which has a different tilt angle and shape.
[0010] In the preferred embodiment of the above-mentioned vehicle daytime running light, the vehicle daytime running light further includes a second reflector disposed within the housing. The second reflector is disposed corresponding to the light source, and the light emitted by the light source is reflected by the second reflector onto the first light-transmitting plate.
[0011] In the preferred embodiment of the above-mentioned vehicle daytime light, the second reflector is disposed opposite to the first light-transmitting plate, and the side of the second reflector opposite to the first light-transmitting plate is an arc-shaped reflective surface, and the light emitted by the light source is reflected onto the first light-transmitting plate through the arc-shaped reflective surface.
[0012] In the preferred embodiment of the above-mentioned automotive daytime running lights, the light source is an LED bulb, and the brightness of the LED bulb is adjustable.
[0013] In the preferred embodiment of the above-mentioned vehicle daytime running light, the vehicle daytime running light further includes a controller, which can adjust the current intensity of the LED beads to achieve adjustable brightness of the LED beads.
[0014] In the preferred embodiment of the above-mentioned automotive daytime light, the first light-transmitting plate and the first prism structure are integrally pressed and formed, and / or
[0015] The second light-transmitting plate and the second prism are integrally pressed and formed.
[0016] In a second aspect, the present invention also provides an automobile, the automobile including the above-mentioned vehicle daytime running lights.
[0017] Those skilled in the art will understand that the present invention provides an automotive daytime running light, including a housing and a light source disposed within the housing. A transparent lampshade is provided at the front end of the housing. The automotive daytime running light also includes a first light-transmitting plate and a second light-transmitting plate disposed within the housing. The first and second light-transmitting plates are arranged sequentially along the direction from the light source towards the lampshade. A first prism structure is provided on the first light-transmitting plate, and a second prism structure is provided on the second light-transmitting plate. By adopting the above technical solution, the present invention can solve the problem that automotive daytime running lights lack the effect of presenting starry night skies and dynamic daytime lighting effects. Specifically, the first prism structure can change the propagation path of light, causing light to produce light spots of varying brightness as it passes through; the second prism structure can further change the propagation direction of light, transforming the light spot effect originally produced by the first light-transmitting plate into a more three-dimensional and layered starry sky effect. This allows the daytime running lights to create a dreamlike starry sky effect at night, bringing a pleasant visual experience to drivers and passengers; during the day, due to the multiple layers of refraction and scattering of light, the daytime running lights appear brighter and more dazzling, presenting a dazzling appearance with dynamic light effects.
[0018] Furthermore, the automotive daytime running light of this invention also includes a first reflector disposed within the housing. The first reflector is located downstream of the first light-transmitting plate and has a reflective surface. Light refracted by the first light-transmitting plate is reflected onto the reflective surface and then onto the second prism structure. This arrangement increases the number of reflections of light within the lamp, allowing more light to be utilized and redirecting light that might otherwise be lost. This makes the light spot effect more pronounced and three-dimensional under the action of the second prism structure, thereby further enhancing the layering and uniformity of the light effect.
[0019] Furthermore, the first prism structure of this utility model includes multiple first prism units, which are arranged in a regular or irregular manner on the first light-transmitting plate, and each first prism unit has multiple inclined surfaces. Through this arrangement, light can produce unique light and shadow effects to create a rich variety of visual effects.
[0020] Furthermore, the second prism structure of this invention includes multiple second prism units, which are arranged in a regular or irregular manner on the second light-transmitting plate. Each second prism unit has multiple facets, each with a different tilt angle and shape. This arrangement increases the complexity of the light, making the driving lights more visually vivid and three-dimensional, thereby creating a unique and dynamic light and shadow effect.

[0031] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the following embodiments are described in conjunction with automotive daytime running lights, the daytime running lights provided by the present invention are equally applicable to other products that need to address the lack of nighttime starry sky and daytime dynamic lighting effects in existing lighting fixtures.
[0032] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0033] Based on the background art, existing automotive daytime running lights lack the effect of presenting a starry night sky and dynamic daytime lighting effects. This utility model provides an automotive daytime running light that effectively solves the problem of lacking the effect of presenting a starry night sky and dynamic daytime lighting effects by incorporating a first prism structure and a second prism structure within the running light.
[0034] like Figures 1 to 3As shown, this utility model provides a car daylight, including a housing 1 and a light source 3 disposed within the housing 1. A transparent lampshade 2 is disposed at the front end of the housing 1. The car daylight also includes a first light-transmitting plate 4 and a second light-transmitting plate 5 disposed within the housing 1. The first light-transmitting plate 4 and the second light-transmitting plate 5 are arranged sequentially along the direction from the light source 3 toward the lampshade 2. A first prism structure 41 is disposed on the first light-transmitting plate 4, and a second prism structure 51 is disposed on the second light-transmitting plate 5.
[0035] The housing 1 is the main structure of the driving lamp, used to protect and support the internal components; the lamp cover 2 is located at the front end of the housing 1, used to protect the light source 3 and guide the light to radiate outward; the light source 3 can provide the light required by the driving lamp, and can be an LED, a halogen lamp or other types of lighting source.
[0036] The first light-transmitting plate 4 is located between the light source 3 and the second light-transmitting plate 5, and a first prism structure 41 is provided on it. The first prism structure 41 can change the propagation path of light through optical principles such as refraction, reflection and scattering, redistribute the uniform light, and make the light produce light spots of different brightness when passing through it.
[0037] Preferably, such as Figure 2 As shown, the first prism structure 41 includes a plurality of first prism units, which are arranged in a regular or irregular manner on the first light-transmitting plate 4, and each first prism unit has a plurality of inclined surfaces.
[0038] By refracting the incident light through the first prism unit, the incident light can be split into multiple directions. Some light rays are concentrated in certain areas to form bright spots, while others are dispersed or deflected in other directions to form dark areas. This redistribution of light results in an alternating bright and dark spot effect.
[0039] Furthermore, the surface of the first prism unit not only refracts light but also reflects some of it. The interaction between the reflected and refracted light further enhances the contrast between bright and dark areas. Reflected light at certain angles concentrates in specific areas, forming brighter points; while other areas appear darker due to the lack or weakening of reflected light, thus further enhancing the contrast between bright and dark areas.
[0040] Furthermore, the surface of the first prism unit of this invention is not completely smooth, but has a certain degree of roughness. This rough surface scatters light, causing the light to no longer concentrate in one direction after passing through the first prism unit, but instead form multiple tiny light spots. These light spots, due to their different scattering angles, exhibit varying degrees of brightness, further enhancing the visual effect of "dynamic light effect presentation."
[0041] The automotive daytime running light provided by this utility model uses the first prism unit to refract, reflect and dissipate heat, so that when light passes through the first prism structure 41, it produces light spots of different brightness, thus enabling the automotive daytime running light to present a dynamic light effect even during the day.
[0042] For example, the first prism unit in this invention is a simple geometric shape such as a triangular, trapezoidal, or circular prism. Furthermore, the angle and size of the first prism unit are small, primarily used to disperse light and create localized variations in brightness. In addition, the first prism units can be arranged regularly (e.g., in a matrix) or irregularly (e.g., randomly) to create natural variations in brightness.
[0043] For example, such as Figure 2 As shown, the first prism unit adopts a miniature triangular prism unit with a prism angle of 60°. The triangular prism units are arranged irregularly on the first light-transmitting plate 4. When light encounters the first prism unit, some light is refracted to form bright light spots, while other light is reflected or scattered to form darker areas. Finally, the light is emitted from the first prism structure 41, forming an alternating bright and dark light spot effect.
[0044] It should be noted that the size, shape and arrangement of the first prism unit can be customized according to design requirements, thereby creating a wide variety of visual effects. This utility model does not impose any specific limitations on these aspects.
[0045] The second light-transmitting plate 5 is located behind the first light-transmitting plate 4, and a second prism structure 51 is provided on it. The second prism structure 51 makes the light spot effect originally produced by the first light-transmitting plate 4 appear to have depth and distance through the refraction and reflection of light, thereby enhancing the three-dimensionality of the light spot. Through the random distribution and dynamic changes of light, it can simulate the twinkling of the starry sky.
[0046] Preferably, such as Figure 3 As shown, the second prism structure 51 includes multiple second prism units, which are arranged in a regular or irregular manner on the second light-transmitting plate 5. Each second prism unit has multiple cut surfaces, and each cut surface has a different tilt angle and shape.
[0047] The second prism units can be arranged on the second light-transmitting plate 5 in a regular (e.g., matrix) or irregular manner. A regular arrangement brings an orderly and harmonious aesthetic, while an irregular arrangement produces a more dynamic and random visual effect. By setting multiple facets on the surface of the second prism unit, light undergoes a complex refraction process as it passes through it; that is, the light undergoes different degrees of refraction, reflection, and scattering. This diversity not only increases the complexity of the light but also makes the driving lights more visually vivid and three-dimensional, thus creating a unique and dynamic light and shadow effect.
[0048] For example, the second prism unit has a more complex structure than the first prism unit. For instance, the second prism unit can be a polyhedral prism (such as a pyramid, cone, or sphere) to increase the refraction and reflection paths of light. Furthermore, the size of the second prism unit is larger than that of the first prism unit, thereby enhancing the sense of depth in the light as it passes through it. Further, the second prism units can be arranged irregularly or in a gradient pattern to simulate the natural distribution of stars in the sky.
[0049] For example, the second prism unit employs miniature pyramid-shaped prism units, each with four bevels at a 45° angle, arranged irregularly on the second light-transmitting plate 5. Thus, light entering the second prism structure 51 from the first prism structure 41 encounters the pyramid-shaped prism units, where some light is refracted in different directions, creating light spots at varying distances. Other light is reflected within the prism units, forming a darker background light. Finally, the light exits from the surface of the second prism structure 51, creating a richly layered starry sky effect.
[0050] It should be noted that the size, shape and arrangement of the second prism unit can be customized according to design requirements, thereby creating a wide variety of visual effects. This utility model does not impose any specific limitations on these aspects.
[0051] Therefore, this utility model, through the combination of multi-layer light-transmitting panels and special optical structure, enables the daytime running lights to present a dreamlike starry sky effect at night; even during the day, due to the light being refracted and scattered through multiple layers, the daytime running lights appear brighter and more dazzling, presenting a dazzling appearance with dynamic light effects, thus enhancing the overall appearance and recognizability of the vehicle.
[0052] Preferably, the light source 3 is an LED lamp bead, and the brightness of the LED lamp bead is adjustable.
[0053] LED bulbs are highly energy-efficient, consuming less energy and producing higher luminous efficiency compared to traditional light sources. This means that LED bulbs consume less electricity to achieve the same lighting effect, helping to reduce the overall energy consumption of a vehicle. Furthermore, the brightness of LED bulbs is adjustable, allowing users to customize the daytime running lights to their preferences and driving style, creating unique and personalized lighting effects. For example, during bright sunlight, the brightness of the LED bulbs can be increased, ensuring the car's daytime running lights present a dazzling, dynamic lighting effect.
[0054] Preferably, the vehicle daytime running lights also include a controller (not shown in the figure), which can adjust the current intensity of the LED beads to achieve adjustable brightness of the LED beads.
[0055] By precisely controlling the current intensity of the LED beads, the controller can achieve continuous and stepless adjustment of the LED bead brightness. This adjustment method is not only more precise but also ensures that the LED beads maintain stable luminous performance under different brightness levels. The controller can integrate intelligent algorithms to automatically adjust the brightness of the daytime running lights based on factors such as ambient light, vehicle speed, and turn signals, achieving a more intelligent and user-friendly lighting effect.
[0056] Preferably, such as Figure 1 As shown, the car daytime running light also includes a first reflector 6 disposed inside the housing 1. The first reflector 6 is disposed downstream of the first light-transmitting plate 4. The first reflector 6 has a reflective surface 61. Light refracted by the first light-transmitting plate 4 shines on the reflective surface 61 and is reflected onto the second prism structure 51.
[0057] During the daytime, to further enhance the brightness of the daytime running lights and create a dynamic lighting effect, this invention incorporates a first reflector 6 with a reflective surface 61. This effectively reflects the light emitted by the light source 3 onto the second prism structure 51. This design increases the number of reflections within the light source, allowing more light to be utilized and redirecting potentially lost light. The resulting spot effect becomes more pronounced and three-dimensional under the action of the second prism structure 51, further enhancing the layering and uniformity of the lighting effect. This design makes the daytime running lights appear brighter and more dazzling during the day, presenting a brilliant appearance with dynamic lighting effects.
[0058] Furthermore, due to the presence of the first reflector 6, the light emitted by the light source 3 is utilized more fully, thereby improving the energy efficiency of the daytime running lights. This means that under the same lighting requirements, this design can reduce the power consumption of the light source 3, contributing to energy conservation and emission reduction, and aligning with the energy-saving and environmentally friendly concepts of the modern automotive industry.
[0059] For example, the reflective surface 61 can be an aluminum-plated surface, a chrome-plated surface, or a silver-plated surface, etc. These materials can effectively reflect light and improve lighting efficiency. This utility model does not limit the specific material of the reflective surface 61.
[0060] Preferably, the first reflector 6 is positioned downstream of the first light-transmitting plate 4 and below the second light-transmitting plate 5. This arrangement makes the first reflector 6 invisible from the outside of the daytime running light. This concealed design not only maintains the neatness and aesthetics of the daytime running light's appearance but also avoids any visual interference or abruptness that the first reflector 6 might cause.
[0061] It should be noted that in other embodiments, the shape, size, and position of the first reflector 6 can be adjusted to customize unique driving light effects to meet aesthetic and personalization requirements. This invention does not specifically limit the shape, size, and position of the first reflector 6.
[0062] Preferably, such as Figure 1 As shown, the car daytime running light also includes a second reflector 7 disposed inside the housing 1. The second reflector 7 is disposed corresponding to the light source 3, and the light emitted by the light source 3 is reflected by the second reflector 7 onto the first light-transmitting plate 4.
[0063] The second reflector 7 is positioned corresponding to the light source 3. Its main function is to reflect the light emitted directly from the light source 3 and guide it to the first light-transmitting plate 4, ensuring that more light can be effectively utilized and reducing light waste. Furthermore, through the reflection of the second reflector 7, the light can be distributed more evenly on the first light-transmitting plate 4. This not only improves the brightness of the daytime running lights but also makes the light effect softer and more uniform, reducing glare and eye strain.
[0064] The second reflector 7 works in conjunction with components such as the first light-transmitting plate 4 and the second light-transmitting plate 5 to significantly enhance the luminous efficiency of the daytime running lights. When the reflected light passes through the first prism structure 41 on the first light-transmitting plate 4 and the second prism structure 51 on the second light-transmitting plate 5, it produces more complex and varied light patterns, thereby enhancing the visual appeal of the daytime running lights.
[0065] Preferably, such as Figure 1 As shown, the second reflector 7 is arranged opposite to the first light-transmitting plate 4, and the side of the second reflector 7 facing the first light-transmitting plate 4 is an arc-shaped reflective surface 71. The light emitted by the light source 3 is reflected onto the first light-transmitting plate 4 through the arc-shaped reflective surface 71.
[0066] The curved reflective surface 71 can more effectively focus and redistribute the light emitted by the light source 3. When light is reflected on the curved surface, it is guided in a specific direction according to the law of reflection, thereby enhancing the light intensity and uniformity on the first light-transmitting plate 4 and reducing blind spots. As a result, the light reflected by the curved reflective surface 71 produces more complex and varied light patterns when it passes through the first light-transmitting plate 4, further enhancing the illumination effect of the daytime running lights and providing more complex and varied light patterns.
[0067] It should be noted that, in order to ensure that light can be reflected evenly and efficiently onto the first light-transmitting plate 4, the curvature of the arc-shaped reflective surface 71 can be precisely calculated according to the type, location, and lighting requirements of the light source 3. For example, the optimal curvature value can be determined through simulation experiments and field tests to achieve the best lighting and visual effects. This invention does not impose a specific limitation on the curvature of the arc-shaped reflective surface 71.
[0068] It should be further noted that the second reflector 7 can be an aluminum-plated plate, a chrome-plated plate, or a silver-plated plate, etc. These materials can effectively reflect light, improve lighting efficiency, and withstand high temperatures, thus ensuring that the second reflector 7 can maintain its high-efficiency reflective performance over a long period of time.
[0069] Preferably, the first light-transmitting plate 4 and the first prism structure 41 are integrally pressed and formed, and the second light-transmitting plate 5 and the second prism structure 51 are integrally pressed and formed.
[0070] The one-piece molding process ensures the precision and consistency of the first prism structure 41 and the second prism structure 51. This high-precision manufacturing method ensures that the structure on each light-transmitting panel meets design requirements, thereby guaranteeing the overall lighting effect and aesthetics of the daytime running light. The one-piece molding process also ensures that the structure on the light-transmitting panel is perfectly integrated with the panel itself, presenting a smooth and natural visual effect, thus enhancing the attractiveness of the daytime running light and improving the user's driving experience.
[0071] In addition, this utility model also provides a car, which includes the above-mentioned car daytime running lights.
[0072] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
