Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of luminous decorative parts for passenger vehicles, specifically to a light guide block structure with high side brightness and uniformity. Background Technology
[0002] In the passenger vehicle sector, illuminated decorative elements are becoming increasingly crucial for enhancing the user experience. Among these, paddle switches are typically located below the steering wheel. Previous solutions often used front-emitting LEDs to achieve the illumination effect.
[0003] However, due to the generally limited height in this area, coupled with the inherent limitations of the emitting angle of positively emitting LEDs, a larger number of positively emitting LEDs must be used to ensure sufficient illumination of the area. This not only increases costs and energy consumption but may also cause inconvenience to vehicle interior design due to the excessive space occupied by too many components, making it difficult to meet people's growing demands for more refined and simplified automotive interiors.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] In view of the problems in related technologies, the purpose of this utility model is to propose a light guide block structure with high side brightness and uniformity, so as to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] The technical solution of this utility model is implemented as follows:
[0007] A light guide block structure with high side brightness and uniformity includes: a light guide substrate, wherein a light incident surface is provided on one side of the light guide substrate, a light emitting surface is provided at the top of the other side of the light guide substrate, and a dot matrix structure is provided at the bottom of the light guide substrate to adapt to the light emitting surface;
[0008] The dot matrix structure is an array of spherical grooves.
[0009] Furthermore, the light guide substrate has a curved structure.
[0010] Furthermore, hooks are provided on both sides of the light guide substrate.
[0011] The beneficial effects of this utility model are:
[0012] This invention utilizes a dot matrix structure to diffuse light as it enters from the light-incident surface and propagates along the light-guiding substrate. When the light reaches below the light-exiting surface, the dot matrix structure causes diffuse reflection, thereby changing the direction of light propagation and allowing more light to exit from the light-exiting surface. In terms of optical performance control, the dot matrix structure design not only allows for flexible adjustment of the overall brightness of the light-exiting surface but also enables precise control of local brightness, thus achieving uniform adjustment of the brightness of the light-exiting surface. This meets diverse lighting needs and enhances the user's visual experience inside the vehicle.
[0013] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention are realized and obtained through the structures particularly pointed out in the description and the accompanying drawings.
[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0021] According to an embodiment of the present invention, a light guide block structure with high side brightness and uniformity is provided.
[0022] like Figures 1-2 As shown, a light guide block structure with high side brightness and uniformity includes: a light guide substrate 1, a light incident surface 2 on one side of the light guide substrate 1, a light emitting surface 3 at the top of the other side of the light guide substrate 1, and a dot matrix structure 5 adapted to the light emitting surface 3 at the bottom of the light guide substrate 1.
[0023] The lattice structure 5 consists of an array of spherical grooves.
[0024] With the help of the above scheme, light enters from the light-incident surface, propagates along the light-guiding substrate 1, and when it reaches below the light-emitting surface 3, the dot matrix structure 5 causes diffuse reflection of the light, thereby changing the direction of light propagation and allowing more light to be emitted from the light-emitting surface 3. In terms of optical performance control, the dot matrix structure 5 design not only allows for flexible adjustment of the overall brightness of the light-emitting surface, but also enables precise control of local brightness, thereby achieving uniform adjustment of the brightness of the light-emitting surface, meeting diverse lighting needs, and enhancing the user's visual experience in the vehicle.
[0025] In addition, the light guide substrate 1 has a curved shape. Hooks 4 are provided on both sides of the light guide substrate 1.
[0026] This technical solution, with its curved structure and hook 4 design, meets actual assembly requirements. In terms of space utilization, its improved design greatly reduces the space occupancy rate and effectively solves the problem of difficult placement of luminous decorative parts in space-constrained areas, providing a wider creative space for automotive interior design.
[0027] Furthermore, for the aforementioned dot matrix structure 5, which is an array of spherical grooves, the density, size, and position can be adjusted according to actual needs to meet requirements. This allows for the adjustment of the density of the dot matrix structure 5 to control the amount of light emitted from the light-emitting surface, i.e., the brightness. It also allows for the adjustment of the density of local dots to adjust the local brightness, thereby adjusting the uniformity.
[0028] In summary, the following effects can be achieved by utilizing the above-mentioned technical solution of this utility model: In terms of optical performance control, the dot matrix structure 5 design not only allows for flexible adjustment of the overall brightness of the light-emitting surface, but also enables precise control of local brightness, thereby achieving uniform adjustment of the brightness of the light-emitting surface, meeting diverse lighting needs, and enhancing the user's visual perception and experience in the vehicle; In terms of space utilization, the improved design greatly reduces the occupancy rate of space height, effectively solving the problem of the difficulty in arranging luminous decorative parts in space-constrained areas, and providing a wider creative space for automotive interior design.
[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
