[0026] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus repeated descriptions thereof will be omitted.

[0027] The technical solutions of the embodiments of the present application will be briefly described below:

[0028] According to some embodiments, as Figures 1 to 2 shown, the present application provides a light guide plate with uniform illumination, and the light guide plate includes:

[0029] As Figure 1 shown, a plate body 1, and the first side surface of the plate body 1 is set as the light receiving end;

[0030] As Figures 1 to 2 shown, multiple light guide beads 2, and the multiple light guide beads 2 are arranged on the second side surface adjacent to the first side surface of the plate body 1, that is, the second side surface adjacent to the light receiving end;

[0031] The multiple light guide beads 2 are arranged on the second side surface of the plate body 1 according to a preset shape, and the preset shape can be set according to actual needs;

[0032] The spacing between the multiple light guide beads 2 in the illumination direction decreases in sequence, and the illumination direction is the direction from the light receiving end to the other end opposite to the light receiving end.

[0033] Specifically, the layout of the multiple light guide beads 2 is such that the spacing between the multiple light guide beads 2 on the side close to the light receiving end is the largest; the farther away from the light receiving end, the smaller the spacing between the multiple light guide beads 2. That is to say, the distance between the light guide beads 2 and the light receiving end is inversely proportional to the spacing between the multiple light guide beads 2.

[0034] Among them, the light guide beads 2 can enhance the light guiding effect. The present application enhances the light guiding effect at positions farther away from the light receiving end and reduces the light guiding effect at positions closer to the light receiving end, so as to make the overall illumination of the light guide plate uniform.

[0035] The following will be further elaborated in detail on the preferred embodiments of the present disclosure in conjunction with the attached Figures 1 to 2 drawings of this specification.

[0036] According to some embodiments, as Figure 1 、 Figure 3 shown, the multiple light guide beads 2 are arranged to form multiple arcs, and the center sides of the multiple arcs all face the side of the light receiving end.

[0037] Specifically, asFigure 3 As shown Figure 3 When drawing multiple light guide beads 2 in CAD, first draw the graphics of multiple arc-shaped light guide beads 2, and then as Figure 1 shown, retain multiple light guide beads 2 within the preset shape and delete multiple light guide beads 2 outside the preset shape to obtain Figure 1 .

[0038] Arrange multiple light guide beads 2 to form multiple arcs. The arcs' centers are oriented towards the light-receiving end. The function of the light-receiving end is to receive light. It is set according to the illumination direction of the light. The closer to the light-receiving end, the larger the spacing between multiple light guide beads 2; the farther from the light-receiving end, the smaller the spacing between multiple light guide beads 2. Finally, it is set into an arc shape to facilitate uniform illumination.

[0039] Furthermore, in some preferred embodiments, the multiple arcs are set as concentric arcs.

[0040] Furthermore, in some embodiments, the spacing between every two light guide beads 2 on the arc is set to be the same, and the spacing between multiple arcs decreases successively along the illumination direction. This application enhances the light guide effect at positions farther from the light-receiving end and reduces the light guide effect at positions closer to the light-receiving end, so as to make the overall illumination of the light guide plate uniform.

[0041] According to some embodiments, as Figure 2 shown, an edge groove 3 is provided at the edge of the preset shape.

[0042] In some embodiments, the edge groove 3 is set as a V-shaped edge groove 3.

[0043] In addition to the above embodiments, it can also be set that a groove with a preset shape is provided on the second side surface of the plate body 1, and multiple light guide beads 2 are arranged in the groove.

[0044] Based on the above embodiments, providing an edge groove 3 at the edge of the preset shape, or providing a groove with a preset shape on the second side surface of the plate body 1, and arranging multiple light guide beads 2 in the groove can both achieve the effect of light locking, making the pattern outline distinct for easy user recognition.

[0045] According to some embodiments, as Figure 1 shown, this application provides a marker lamp, which includes the above light guide plate and a lighting lamp 4. The light outlet of the lighting lamp 4 is connected to the light-receiving end of the plate body 1.

[0046] Among them, the preset shape is the shape of the marker pattern, and the preset shape can be set according to actual needs.

[0047] In the description of the above embodiments, specific features, structures, materials, or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0048] While the present disclosure has been described with reference to several exemplary embodiments, it should be understood that the terms used are descriptive and exemplary, rather than restrictive. Since the present disclosure can be embodied in many forms without departing from the spirit or essence of the application, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but rather should be broadly construed within the spirit and scope defined by the appended claims, and thus all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
