Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to a novel automotive grille light. Background Technology

[0002] Currently, automotive grille lights, as a crucial component for enhancing vehicle visibility and nighttime safety, are receiving considerable attention for their technological development. Existing automotive grille light technologies, such as the one described in patent number CN201620112706.1, primarily involve placing the headlight body between the radiator and the grille itself, and covering its outer surface with a flat lampshade. This design aims to uniformly reduce the light intensity through the flat lampshade, making it softer and compensating for blind spots in the headlights while preventing glare for oncoming vehicles.

[0003] However, in practice, it has been found that such existing technologies have the following inherent defects: First, their optical systems are extremely rudimentary, relying solely on a "flat lampshade" for physical light reduction. While this avoids glare, it causes a severe loss of luminous efficiency and cannot achieve precise control over the light pattern, resulting in a rough and inefficient lighting effect. Second, their light sources mostly adopt an integrated design. Once a single LED chip fails, the entire lamp module must be disassembled and replaced, making the repair process complex, costly, and extremely inconvenient for users. Third, this structure does not adequately consider heat dissipation. The heat generated by the LED chips is difficult to dissipate quickly, which can easily lead to accelerated chip light decay and seriously affect the lifespan and reliability of the lamp. Finally, their overall structure is bulky and has low integration, making it difficult to adapt to the current design requirements of thinner and more compact automotive grilles, thus limiting installation flexibility and aesthetics. Summary of the Invention

[0004] The purpose of this utility model is to solve the shortcomings of existing automotive grille lights, such as rudimentary optical systems, integrated design, insufficient heat dissipation, bulky overall structure, resulting in loss of light efficiency, inability to achieve precise control of light pattern, complex and costly maintenance process, poor heat dissipation effect of lamps, and difficulty in achieving compact design. Therefore, a new type of automotive grille light is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel automotive grille light is designed, comprising a radiator housing 1 and a lens module 2 mounted on the front end of the radiator housing 1. An LED light source module 3, corresponding to the lens module 2, is installed inside the radiator housing 1. The LED light source module 3 has multiple sets of LED low beam light source substrates 31 arranged in parallel left and right. The LED low beam light source substrates 31 have LED low beam light source beads 311 with upward light source. A reflector cup 4 with the light outlet facing the lens module 2 is independently covered above the LED low beam light source beads 311. A light-blocking strip 5 is also provided in front of the LED low beam light source beads 311. The reflector cup 4, the LED low beam light source substrate 31, and the light-blocking strip 5 are stacked in sequence. The rear end of the radiator housing 1 has a forward-recessed mounting groove 11, and a heat dissipation module 6 is provided in the mounting groove 11.

[0007] Furthermore, the LED light source module 3 includes a supplementary light source substrate 32, on which LED low beam compensation light source beads 321 and LED high beam compensation light source beads 322 are arranged and oriented towards the lens module 2. The LED low beam compensation light source beads 321 are located above the LED high beam compensation light source beads 322.

[0008] Furthermore, the supplementary light source substrate 32 is disposed in the center of the plurality of LED low beam light source substrates 31.

[0009] Furthermore, the LED light source module 3 also includes a high beam supplementary light substrate 33, on which are provided LED high beam light source beads 331 arranged in a circle with the light source facing the lens module 2.

[0010] Furthermore, multiple sets of LED low beam light source substrates 31 are centrally arranged, and the supplementary light source substrate 32 and the high beam supplementary light substrate 33 are symmetrically distributed on the left and right sides of the multiple sets of LED low beam light source substrates 31.

[0011] Furthermore, the lens module 2 includes a low-beam lens 21, a supplementary light source substrate 32, and a high-beam supplementary light substrate 33, which are respectively disposed corresponding to the LED low-beam light source substrate 31, the supplementary light source substrate 32, and the high-beam supplementary light substrate 33.

[0012] Furthermore, the left and right sides of the radiator lamp housing 1 are provided with fixing brackets 12 for fixing it to the vehicle frame. The rear end of the radiator lamp housing 1 is covered with a lamp housing rear cover 13. The lamp housing rear cover 13 is provided with heat dissipation holes 131 corresponding to the heat dissipation module 6. The front end of the radiator lamp housing 1 is also provided with a lens cover plate 14 pressed on the lens module 2. The lens cover plate 14 has a lens opening 141 for the lens module on the lens module 2 to pass through.

[0013] Furthermore, the top of the radiator lamp housing 1 is provided with a removable cover plate 15.

[0014] Furthermore, the light-blocking strip 5 includes a fixed support plate 51 fixed to the lower end of the LED low beam light source substrate 31, and the front end of the fixed support plate 51 is provided with a light-blocking strip body 52 located in front of the LED low beam light source lamp bead 311 and higher than the LED low beam light source lamp bead 311.

[0015] The novel automotive grille light proposed in this utility model has the following advantages:

[0016] In this utility model, the application achieves precise control of light through a multi-level optical system consisting of an independent reflector cup, a light-blocking strip, and a lens module. While providing good illumination, it fundamentally solves the glare problem, far exceeding the soft light effect of a simple flat lampshade.

[0017] Secondly, in this utility model, the stacked design of the optical unit and the embedded installation of the heat dissipation module make the entire lamp structure very compact, making it easier to integrate into the space-constrained interior of the car's grille, which meets the design requirements of modern automobiles.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figures 1-9A novel automotive grille light includes a radiator housing 1 and a lens module 2 mounted on the front end of the radiator housing 1. The lens module 2, as a light-emitting surface, can perform secondary light distribution to form a low beam pattern that meets regulations and design requirements, while protecting the internal optical components from dust and moisture corrosion. The radiator housing 1 houses an LED light source module 3, which corresponds to the lens module 2. The LED light source module 3 has multiple sets of LED low beam light source substrates 31 arranged in parallel. The LED low beam light source substrates 31 have upward-facing LED low beam light source beads 311 to provide the main low beam illumination function. Above each LED low beam light source bead 311, there is an independent reflector cup 4 with the light outlet facing the lens module 2. This cup can accurately and efficiently collect and reflect light, reduce stray light, and concentrate the light onto the lens, greatly improving the utilization rate of the light source. A light-blocking strip 5 is also provided in front of each LED low beam light source bead 311. The light-blocking strip 5 can be located at the light outlet of the reflector cup 4. It can effectively block the excess upward light emitted directly from the LED low beam light source bead 311. This is a key component for forming a clear and sharp low beam cutoff line, avoiding glare for oncoming vehicles and pedestrians. The reflector cup 4, the LED low beam light source substrate 31, and the light-blocking strip 5 are stacked sequentially to form a compact and efficient optical unit, which is beneficial for the thinning and miniaturization of the lamp. The rear end of the heat sink housing 1 has a recessed mounting groove 11, and the heat dissipation module 6 is provided in the mounting groove 11. This application provides a precise installation position and space for the heat dissipation module 6 by recessing a mounting groove 11 at the rear end of the heat sink housing 1, which makes the overall structure more compact and saves installation space. At the same time, the heat dissipation module 6 can dissipate the heat conducted from the heat sink housing 1 to the surrounding environment, ensuring that the LED operates at a suitable temperature, preventing light decay and sudden reduction in lifespan due to overheating, and ensuring that the lamp can work stably and reliably for a long time.

[0030] In detail, this application achieves precise control of light through a multi-level optical system consisting of an independent reflector cup, a light-blocking strip, and a lens module. While providing good illumination, it fundamentally solves the glare problem, far exceeding the soft light effect of a simple flat panel lampshade.

[0031] Meanwhile, by adopting a modular design with multiple independent LED low beam light source substrates 31, when individual LED beads are damaged, it is not necessary to replace the entire large assembly or light source module; only the corresponding single substrate needs to be replaced. The maintenance operation is simple, quick, and extremely low in cost.

[0032] Furthermore, this application adopts an integrated heat sink and lamp housing design combined with an independent heat dissipation module at the rear end, which can form an efficient heat conduction path, quickly conduct and dissipate the heat generated by the LED, effectively suppress the rise of the chip junction temperature, significantly extend the service life of the lamp, and ensure long-lasting and stable luminous efficacy.

[0033] Finally, this application achieves a very compact lamp structure through the stacked design of the optical unit and the embedded installation of the heat dissipation module, making it easier to integrate into the space-constrained interior of the car's grille, thus meeting the design requirements of modern automobiles.

[0034] More specifically, in this utility model, the lighting process is as follows: First, the LED low beam light source bead 311 is powered on and emits light. Then, its light is collected, reflected, and guided to the lens module 2 by the independent reflector cup 4 above it. At the same time, the light-blocking strip 5 in front of the LED low beam light source bead 311 can block part of the upward light, initially forming a light-dark cutoff line. After the reflected and initially blocked light enters the lens module 2, the lens module 2 can perform final shaping and diffusion of the light, projecting a low beam spot that meets the requirements.

[0035] More specifically, in this utility model, the heat dissipation process of this application is as follows: First, the LED low beam light source bead 311 can generate a lot of heat when it is working. This heat can be transferred to the LED low beam light source substrate 31 first, and then quickly conducted to the heat sink housing 1 that is in close contact with it. Subsequently, the heat can be conducted along the heat sink housing 1 to the mounting groove 11 area at the rear end, and finally the heat dissipation module 6 integrated therein (such as aluminum fin passive heat dissipation or fan active heat dissipation) dissipates the heat into the air.

[0036] Furthermore, in this embodiment, as Figure 4 , Figure 5 , Figure 7 and Figure 9 As shown, the LED light source module 3 includes a supplementary light source substrate 32. The supplementary light source substrate 32 is provided with LED low beam compensation light source beads 321 and LED high beam compensation light source beads 322 arranged with their light sources facing the lens module 2. The LED low beam compensation light source beads 321 can be specifically used to compensate for the low beam illumination area (such as increasing the illumination width or the brightness of a specific area). The LED high beam compensation light source beads 322 can provide a concentrated long-distance illumination beam. The LED low beam compensation light source beads 321 are located above the LED high beam compensation light source beads 322. This layout is optically designed. In vehicle lighting, the low beam needs to form a clear "Z"-shaped cutoff line with a lower left side and a higher right side to prevent glare. Therefore, placing the LED low beam compensation light source beads 321 above is more conducive to forming an accurate low beam cutoff line together with the main low beam. The high beam does not have this limitation and can form a stronger central focusing effect when concentrated below.

[0037] In detail, in this embodiment, two types of compensation light sources are integrated on the supplementary light source substrate 32, enabling the lamp to have the following capabilities: 1. Enhance low beam: the low beam lighting effect is broadened or enhanced by the LED low beam compensation light source beads 321; 2. Provide high beam: the high beam lighting function is realized by the LED high beam compensation light source beads 322, so that the grille light is no longer a single low beam auxiliary light, but a complete lighting system.

[0038] To elaborate further, in this utility model, the grille light is no longer just a low beam auxiliary light, but a complete "low beam + high beam" lighting system. Through independent compensation lamp beads and a precise optical system, it can achieve wider and more uniform low beam lighting and farther and more concentrated high beam lighting, thus improving the lighting performance in all aspects.

[0039] Furthermore, since the LED low beam compensation light source 321 and the LED high beam compensation light source 322 are independently controlled, this lays the foundation for realizing complex light patterns (such as adaptive high beam ADB). By controlling the lighting and extinguishing of different light sources, it is possible to automatically avoid oncoming vehicles or pedestrians while illuminating the road ahead, thus achieving intelligent lighting.

[0040] More specifically, this application may include three lighting modes: 1. Basic low beam mode, which only illuminates the LED low beam light source 311 to provide standard basic low beam illumination. 2. Enhanced low beam mode, which, in the basic low beam mode, also illuminates the LED low beam compensation light source 321 to enhance the lighting effect in situations requiring wider and brighter low beam illumination, such as rural roads or rainy days. 3. High beam mode, which, in the enhanced low beam mode, illuminates the LED high beam compensation light source 322 to provide long-distance illumination.

[0041] Furthermore, in this embodiment, as Figure 4 , Figure 5 and Figure 9 As shown, the supplementary light source substrate 32 is positioned in the center of the multiple sets of LED low beam light source substrates 31. Its light can naturally diffuse outwards from the core area of ​​the light pattern, making the low beam illumination more uniform and wide, while the high beam illumination is concentrated and powerful. This eliminates the disharmony between the supplementary light and the main light, and the light pattern meets high-level regulations and aesthetic requirements. Simultaneously, it ensures the symmetry and concentration of the high beam, making the high beam function of this grille light not just "present," but "excellent," truly possessing the practical value of a main high beam light.

[0042] Furthermore, in this embodiment, as Figure 7As shown, the LED light source module 3 also includes a high beam supplementary light substrate 33. The high beam supplementary light substrate 33 has LED high beam light source beads 331 arranged in a circle with their light source facing the lens module 2. The LED high beam light source beads 331 can generate a high-intensity, highly concentrated core high beam spot, which, combined with the LED high beam compensation light source beads 322, forms a powerful and complete high beam. Furthermore, all functions of the LED light source module 3 are implemented by independent substrate modules. If any light source substrate is damaged, it can be replaced independently, resulting in the lowest maintenance cost and high efficiency, solving the pain point of "replacing the entire assembly when a small part fails" in integrated headlights.

[0043] Furthermore, in this embodiment, as Figure 7 As shown, multiple sets of LED low beam light source substrates 31 are centrally arranged to construct a basic low beam illumination area, avoiding the beam pattern fragmentation that may be caused by excessive dispersion of light sources, and ensuring the integrity and excellent uniformity of the main low beam spot. The supplementary light source substrate 32 and the high beam supplementary light substrate 33 are symmetrically distributed on the left and right sides of the multiple sets of LED low beam light source substrates 31 to be responsible for beam pattern enhancement in specific areas.

[0044] Furthermore, in this embodiment, as Figure 1-9 As shown, the lens module 2 includes a low-beam lens 21, a supplementary light source substrate 32, and a high-beam supplementary light substrate 33 respectively, which are respectively disposed corresponding to the LED low-beam light source substrate 31, the supplementary light source substrate 32, and the high-beam supplementary light substrate 33. This application isolates each optical system so that each functional optical path does not interfere with each other.

[0045] Furthermore, in this embodiment, as Figure 4 , Figure 5 , Figure 7 and Figure 9 As shown, the radiator lamp housing 1 has mounting brackets 12 on both sides for fixing it to the vehicle frame, ensuring the lamp is stable and reliable during vehicle vibration and precise installation. A rear cover 13 is provided at the rear end of the radiator lamp housing 1 to seal the rear end, forming a sealed cavity to prevent dust and moisture from entering and protecting the delicate optoelectronic components. The rear cover 13 has heat dissipation holes 131 corresponding to the heat dissipation module 6, which are key air outlets for active or passive cooling systems. A lens cover 14 is also provided at the front end of the radiator lamp housing 1, pressing against the lens module 2, which enhances the aesthetics of the lamp and its integration with the overall vehicle design. The lens cover 14 has lens openings 141 for the lens modules of the lens module 2 to pass through, providing precise exposure windows for each lens on the lens module 2, ensuring unobstructed light paths, and providing axial positioning for the lens modules.

[0046] Furthermore, in this embodiment, as Figure 9 As shown, the top of the heat sink lamp housing 1 is provided with a removable cover plate 15, which allows direct access to the internal LED light source module 3 without disassembling the entire lamp body or the front lens cover plate 14. When a light source substrate needs to be replaced, this cover plate 15 can be opened for operation, effectively improving maintenance speed and convenience. Furthermore, on the production line, this cover plate 15 facilitates workers in connecting internal wiring harnesses, installing components, and performing preliminary optical adjustments.

[0047] Furthermore, in this embodiment, as Figure 4 , Figure 5 , Figure 7 and Figure 9 As shown, the light-blocking strip 5 includes a fixed support plate 51 fixed to the lower end of the LED low beam light source substrate 31, which can increase the connection area with the LED low beam light source substrate 31 and strengthen the connection and fixation. The front end of the fixed support plate 51 is provided with a light-blocking strip body 52 located in front of the LED low beam light source lamp bead 311 and higher than the LED low beam light source lamp bead 311, so as to intercept the light that is directly incident on the upper part of the lens. Its height is higher than the LED low beam light source lamp bead 311, which can effectively block the upward light with a large angle emitted from the center of the lamp bead. Thus, together with the reflector and the lens, it can create a clear, sharp and glare-free cutoff line.

[0048] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
