Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle lamp illumination, and particularly relates to a high beam module, a vehicle lamp system and a vehicle. Background Art

[0002] In current automotive lighting technology, in order to balance the safety of vehicle driving and the comfort during driving, vehicle lamp systems generally adopt a modular design, and can realize low beam and high beam functions by integrating multiple lighting modules. Specifically, a vehicle lamp system adopting the above design includes at least one low beam module for providing a clear forward view under normal driving conditions, and is equipped with one or more high beam modules for enhancing the visibility of the road when a larger lighting range is required.

[0003] However, this traditional layout method has a significant aesthetic defect, that is, when only the low beam mode is enabled, the high beam module remains extinguished, resulting in obvious dark areas in the overall appearance of the vehicle lamp system, affecting the visual coherence and aesthetics, and not fully meeting consumers' expectations for the refinement of the vehicle appearance.

[0004] In addition, to alleviate the above problems, the prior art has tried to integrate additional optical components inside the high beam module, aiming to achieve a certain degree of lighting effect even in the low beam mode, so as to eliminate or reduce the dark area phenomenon. Although this innovative idea has its own uniqueness, it faces many challenges in specific implementation. For example, integrating the required additional optical components not only requires independent light sources, but may also require complex optical structures, separate circuit boards and even additional connectors, which not only increases the complexity of design and manufacturing, but also often leads to a significant increase in cost. More importantly, due to the additional design limitations of the optical path and the consideration of light source power distribution, these technical solutions are often difficult to achieve the ideal brightness output and uniform lighting effect, resulting in an insufficient overall visual effect after lighting, and not fundamentally solving the problems of low overall brightness and poor lighting effect of the vehicle lamp system.

[0005] Therefore, how to overcome the above technical defects is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a high beam module, a vehicle lamp system and a vehicle, so that the internal layout of the vehicle lamp system is more compact and reasonable, and the overall appearance of the vehicle lamp system can be effectively prevented from having obvious dark areas in the low beam mode.

[0035] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0036] The core of the present utility model is to provide a high - beam module, a vehicle lamp system and a vehicle, so that the internal layout of the vehicle lamp system is more compact and reasonable, and it can effectively avoid obvious dark areas in the overall appearance of the vehicle lamp system in the low - beam mode.

[0037] In order to enable those skilled in the art to better understand the technical solutions provided by the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0038] Specifically, please refer to Figures 1 - 5 , a high - beam module provided by the present utility model is used to cooperate with a low - beam module in the low - beam mode to achieve the effect of reducing dark areas, and includes: a high - beam light source 110, a lighting light source 120, a reflector 200, and an optical lens 300.

[0039] Among them, both the high - beam light source 110 and the lighting light source 120 can be LED lights.

[0040] The reflector 200 includes a high - beam reflecting surface 210 and an auxiliary reflecting surface 230. Both the high - beam reflecting surface 210 and the auxiliary reflecting surface 230 have the ability to reflect light. The high - beam reflecting surface 210 and the auxiliary reflecting surface 230 are not arranged in the same plane, and the high - beam reflecting surface 210 and the auxiliary reflecting surface 230 are an integrally formed structure. The projections of the high - beam reflecting surface 210 and the auxiliary reflecting surface 230 on the optical lens 300 do not overlap or partially overlap.

[0041] In the light propagation direction, the lighting light source 120 is closer to the optical lens 300 than the high - beam light source 110, and the auxiliary reflecting surface 230 is closer to the optical lens 300 than the high - beam reflecting surface 210.

[0042] The reflectivity of the auxiliary reflecting surface 230 can be close to that of the high - beam reflecting surface 210 or not close to that of the high - beam reflecting surface 210. The optical lens 300 can play a role in transmitting light.

[0043] The light emitted by the high-beam light source 110 can be reflected by the high-beam reflecting surface 210 in sequence, then emitted through the optical lens 300 and projected to form a high-beam light pattern. The light emitted by the lighting light source 120 can be reflected by the auxiliary reflecting surface 230 in sequence, then emitted through the optical lens 300 and projected to form a lighting light pattern.

[0044] In the high-beam module provided by this patent, the reflector 200 includes a high-beam reflecting surface 210 and an auxiliary reflecting surface 230, and is an integrally formed structure, making the internal layout of the vehicle lamp system more compact and reasonable, reducing the number of parts, simplifying the assembly process, and thus effectively reducing the production cost. When the vehicle lamp system is in the high-beam mode, the light emitted by the high-beam light source 110 is accurately reflected by the carefully designed high-beam reflecting surface 210, and then passes through the optical lens 300 to converge into a bright and long-distance high-beam. On the basis of the existing technology, a lighting light source 120 and an auxiliary reflecting surface 230 are added. When the vehicle lamp system is in the low-beam mode, the lighting light source 120 is turned on. With the activation of the lighting light source 120, its light passes through the optimized reflection path of the auxiliary reflecting surface 230 and also passes through the optical lens 300, enabling the high-beam module to exhibit an auxiliary, more uniform and directional lighting effect without activating the high-beam light source 110.

[0045] In this design, the reflection angle of the auxiliary reflecting surface 230 is precisely calculated and adjusted. The calculation of this reflection angle is prior art and will not be elaborated here. To ensure that the light it emits can be more effectively projected onto the lens area, thereby enhancing the overall lighting uniformity and aesthetics, and effectively avoiding obvious dark areas in the overall appearance of the vehicle lamp system in the low-beam mode.

[0046] To enhance the visual coherence, the boundary of the auxiliary reflecting surface 230 close to the high-beam reflecting surface 210 is set higher than the boundary of the high-beam reflecting surface 210 close to the auxiliary reflecting surface 230.

[0047] That is, the boundary between the auxiliary reflector 230 and the high beam reflector 210 is specially designed so that the projection of the boundary of the auxiliary reflector 230 close to the high beam reflector 210 on the optical lens 300 can partially overlap with the projection of the boundary of the high beam reflector 210 close to the auxiliary reflector 230 on the optical lens 300. When the high beam reflector 210 is located above the auxiliary reflector 230, it can be understood that the boundary of the side of the auxiliary reflector 230 close to the high beam reflector 210 is designed to be slightly higher than the boundary of the corresponding position of the high beam reflector 210. Slightly higher can be understood that the overlapping coverage does not exceed one-tenth of the height of the auxiliary reflector 230 / high beam reflector 210 itself, so it will not interfere with the optical path of the high beam light source 110. The setting of this height difference not only enhances the visual coherence, but more importantly, cleverly shields the stray light that may be generated when the high beam light source 110 is reflected to the edge of the high beam reflector 210, effectively trimming the light pattern of the high beam and ensuring the purity and precise control of the light beam.

[0048] In a specific embodiment, the high beam reflector 210 and the auxiliary reflector 230 are connected by a connecting surface 220. The connecting surface 220 is an inclined surface, that is, the reflector 200 includes a high beam reflector 210, a connecting surface 220 and an auxiliary reflector 230 connected in sequence. The reflector 200 is integrally Z-shaped. The height difference between the high beam reflector 210 and the auxiliary reflector 230 is combined with the inclined surface formed by the connecting surface 220, so that the reflector 200 forms an integrated optical element, significantly reducing the number of components inside the high beam module.

[0049] Based on the above specific embodiment, the high beam light source 110 and the lighting light source 120 are located on the same circuit board 100, which can save the number of components and cost at the same time. As Figure 2 and 3 shown, the high beam light source 110 and the accompanying lighting light source 120 are integrated on the circuit board 100.

[0050] Of course, the high beam light source 110 and the lighting light source 120 can also be located on different circuit boards. The above circuit board can be arranged on the reflector 200 or other components of the high beam module through other brackets.

[0051] By cleverly integrating the high beam reflector 210 and the auxiliary reflector 230 on the same reflector 200, and integrating the high beam light source 110 and the lighting light source 120 on the same circuit board, the compactness and efficiency of the structure are achieved.

[0052] The number of high beam light sources 110 can be one or more, and the number of lighting light sources 120 can also be one or more.

[0053] In a specific embodiment, the high-beam reflecting surface 210 includes two interconnected arc-shaped reflecting surfaces. The reflecting surface composed of two arc-shaped surfaces can more effectively converge the light emitted by the high-beam light source 110 in one direction, making the high-beam light beam more concentrated and able to reach a farther range in terms of illumination distance, helping the driver discover road conditions or obstacles in the distance earlier.

[0054] For example, when the number of high-beam light sources 110 is multiple, the multiple high-beam light sources 110 can be dispersedly arranged above the two arc-shaped reflecting surfaces of the high-beam reflecting surface 210, making the light beam emit more evenly.

[0055] The shapes of the high-beam reflecting surface 210 and the auxiliary reflecting surface 230 can each be any one of a paraboloid-like surface, a plane, an inclined surface, and a cylindrical surface. The two can adopt the same type of shape or different types of shapes. The appearances of the high-beam reflecting surface 210 and the auxiliary reflecting surface 230 can be a high-gloss surface or a matte surface. Of course, the high-beam reflecting surface 210 and the auxiliary reflecting surface 230 can also be other shapes, and no specific limitations are imposed on their shapes and appearances. Specific adaptations are made according to actual applications.

[0056] The high-beam module with the effect of low-beam accompanying lighting provided by this patent, through an integrated design, makes the layout of the high-beam light source 110 and the lighting light source 120 in the vehicle lamp system more compact and reasonable, reduces the number of parts, simplifies the assembly process, and thus effectively reduces the production cost. At the same time, the design of the integrated reflector 200 reduces the dark area phenomenon caused by light source dispersion, enhancing the overall visual beauty and consistency of the vehicle lamp. The uniform illumination effect of the lighting light source 120 further enhances the three-dimensional sense and layering of the front or rear of the vehicle, providing a better visual experience for the driver and external personnel, and also providing more degrees of freedom for vehicle lamp design. By adjusting the shape, size, and position of the auxiliary reflecting surface 230, and optimizing the design of the inclined surface connection surface, the combination mode of the accompanying lighting effect and the high-beam light pattern can be flexibly adjusted, improving the aesthetics and lighting uniformity of the vehicle lamp in the low-beam mode, while being more efficient, economical, and with remarkable effects, meeting the vehicle lamp design requirements of different vehicle models and different styles.
