Description

Technical Field

[0001] The utility model relates to the technical field of light guides, in particular to a light guide component for a turn signal lamp on the upper side of a rearview mirror of an automobile. Background Art

[0002] The side turn signal in the rearview mirror of the car is mandatory by law. At present, the design of the side turn signal of the rearview mirror is mainly integrated light guide and independent light guide. The independent light guide has a separate light guide part compared to the integrated light guide, which is more beautiful in static state. However, the lighting effect of both is vertical stripes (such as Figure 1 As shown), the form is single and cannot meet the customer's demand for diversified lighting effects of the side turn signal. Utility Model Content

[0003] In view of the above shortcomings or deficiencies of the prior art, the technical problem to be solved by the present invention is to invent a new light guide component structure and provide a new side turn signal display effect.

[0004] In order to solve the above technical problems, the utility model has the following structure:

[0005] A plurality of raised optical microstructures are arranged on the surface of the light guide component irradiated by light. The plurality of optical microstructures are arranged in a dot matrix with intervals in both the horizontal and vertical directions, and the number of rows and columns is greater than two.

[0006] The lateral spacing between adjacent optical microstructures in each row is equal, and the longitudinal spacing between adjacent rows is equal.

[0007] Counting from one side, the optical microstructures in even-numbered rows are shifted left or right by half the lateral spacing between the optical microstructures, forming a staggered dot matrix. Each optical microstructure is equidistant from its adjacent optical microstructures.

[0008] The optical microstructure is a cone with a rounded tip, or each optical microstructure is a section of a cylinder with an outer side surface being a circular arc surface.

[0009] Compared with the prior art, the advantages of the present invention are:

[0010] The light emitted by the light source of the turn signal on the upper side of the car's rearview mirror is fully reflected by the dot matrix optical microstructure pattern on the light guide component, which is different from the existing vertical stripe display effect. Instead, it produces a new multi-point lighting effect, which is very novel and fashionable, providing customers with more diverse choices.

[0011] The optical microstructures in even rows are moved to the left or right as a whole to form a staggered dot matrix, and the distance between each optical microstructure and the adjacent optical microstructure is equal. This is the way that best conforms to people's visual habits and aesthetics, and is also the simplest layout method in the production process.

[0012] The optical microstructure is a cone with a rounded tip. The surface reflects light at equal distances from the center, which is conducive to total reflection of light, resulting in a larger lighting range and a more orderly and uniform lighting effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.

[0022] It should be noted that in the description of the present invention, the terms "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings. They are only simplified descriptions for the convenience of describing the present invention. They do not mean that the elements indicated must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limitations on the present invention.

[0023] like Figure 2 、 Figure 3As shown, the side turn signal lamp on the rearview mirror of an automobile consists of a housing 1, a light guide assembly 2, a decorative cover 3, a transparent mask 4, and a light source 5. The decorative cover 3 is connected to the housing 1, and the light guide assembly 2 is clamped and fixed between the two. The outermost transparent mask 4 is fixed to the housing 1, and the circuit board equipped with the light source 5 is installed on the housing 1. The multiple optical microstructures 2a on the light guide assembly 2 of the utility model are arranged in a dot matrix at certain horizontal and vertical intervals, forming an array of optical microstructures 2a (see Figure 4 ), the light from the light source 5 is totally reflected by the pattern of the optical microstructure 2a in the light guide component 2, the stray light in the non-light outlet area is blocked by the decorative cover 3, and finally refracted by the transparent mask 4, forming a regular multi-point lighting effect.

[0024] The light guide assembly 2 of the upper turn signal lamp of the automobile rearview mirror of the present invention is as follows: Figure 4 As shown, the surface of the light guide assembly 2, where light is directed, is decorated with multiple raised optical microstructures 2a. These optical microstructures 2a are arranged in a dot matrix with spacing in both the horizontal and vertical directions, with the number of rows and columns exceeding two. Light emitted from the side turn signal light source 5 is fully reflected by the dot matrix optical microstructures 2a, creating a new, multi-point lighting effect, unlike the existing vertical stripe display. This is a novel and fashionable design, providing customers with more diverse options.

[0025] The lateral spacing between adjacent optical microstructures 2a in each row is equal, and the longitudinal spacing between adjacent rows is equal. This arrangement of equal lateral and longitudinal spacing simplifies the production process.

[0026] Counting from one side, the optical microstructures 2a in even-numbered rows are shifted left or right by half the lateral spacing between the optical microstructures 2a, forming a staggered dot matrix. This staggered dot matrix effect is more dynamic and beautiful than an array arrangement where each element is aligned vertically, horizontally, or leftwards.

[0027] The distance between each optical microstructure 2a and the adjacent optical microstructure 2a is equal. The layout of the optical microstructures 2a with equal distances is the most consistent with people's visual habits and aesthetics, and is also the simplest layout in production technology.

[0028] like Figure 4 As shown, the optical microstructure 2a is a cone with a rounded tip. As a rotating body, the surface of the cone reflects light equidistantly from the center, which is conducive to total reflection of light, resulting in a larger lighting range and a more orderly and uniform lighting effect.

[0029] Figure 5 This is another embodiment of the optical microstructure 2a. Each microstructure is a column with an arc-shaped outer surface, which can also achieve total reflection of light and has a multi-point lighting effect.

[0030] The above embodiments are intended only to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be encompassed by the scope of the claims of the present invention.
