Description

Technical Field

[0001] This utility model belongs to the field of light guide plate technology, and more specifically relates to a high-brightness light guide component. Background Technology

[0002] A light guide assembly is a structure that refracts and reflects a single point light source or a strip of light to form a surface light source. In order to form uniform illumination on the light guide plate, tiny reflective bumps are set on the surface of the light guide plate. If it is irradiated by a single-sided light source, the reflective bumps gradually increase in size from one side of the light source to the other side, as shown in the patent technology with publication number CN117310866A entitled "A Method for Enhancing the Reflective Effect of a Front Light Guide Plate". Alternatively, if it is irradiated by a contralateral light source, the reflective bumps gradually increase in size from both sides of the light source toward the middle, as shown in the patent technology with publication number CN102628975A entitled "Light Guide Plate, Surface Light Source Device, Transmissive Image Display and Light Guide Plate Manufacturing Method". Dual-sided light sources can improve the light intensity, that is, the brightness of the light guide plate.

[0003] However, none of the above structures can accommodate four-sided light sources. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-brightness light guide assembly with light sources set on all four sides of the light guide plate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-brightness light guide assembly, including a light guide plate and strip lights located on the four sides of the light guide plate. The light guide plate is provided with a plurality of spiral-shaped reflective rings that gradually decrease in size towards the center. Each spiral-shaped reflective ring includes a plurality of reflective protrusions. The number of reflective protrusions on each spiral-shaped reflective ring decreases gradually from the outside to the inside, and the size of each reflective protrusion on each spiral-shaped reflective ring increases gradually from the outside to the inside.

[0006] Furthermore, the spacing between adjacent reflective protrusions within the same spiral reflective ring is the same.

[0007] Furthermore, the spacing between two adjacent reflective protrusions within adjacent spiral reflective rings is the same.

[0008] Furthermore, the reflective protrusion is spherical or frustum-shaped.

[0009] Compared with the prior art, the beneficial effect of this utility model is that by setting a spiral reflective ring with gradually increasing reflective protrusions, strip lights can be set on all four sides of the light guide plate, which greatly improves the brightness of the light guide plate.

[0012] In the description of this utility model, it should be noted that the directional terms such as "center", "horizontal (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.

[0013] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0014] Reference Figure 1 The present invention will be further described below.

[0015] A high-brightness light guide assembly includes a light guide plate 1 and strip lights 2 located on the four sides of the light guide plate 1. The light guide plate 1 is provided with a plurality of spiral-shaped reflective rings that gradually decrease in size towards the center. Each spiral-shaped reflective ring includes a plurality of reflective protrusions 3. The number of reflective protrusions 3 on each spiral-shaped reflective ring decreases gradually from the outside to the inside, and the size of each reflective protrusion 3 on each spiral-shaped reflective ring increases gradually from the outside to the inside.

[0016] like Figure 1 As shown, in this example, preferably, by setting a spiral reflective ring with gradually increasing reflective protrusions 3, strip lights 2 can be set on all four sides of the light guide plate 1, which greatly improves the brightness of the light guide plate 1.

[0017] Specifically, the reflective protrusion 3 is located on the surface of the light guide plate 1, and its surface may also be covered with another layer of light guide film.

[0018] Specifically, the strip light 2 and the light guide plate 1 can be bonded together with adhesive or other connection methods or structures in the prior art.

[0019] like Figure 1 As shown in this example, preferably, the spacing between adjacent reflective protrusions 3 within the same spiral reflective ring is the same.

[0020] like Figure 1 As shown in this example, preferably, the spacing between two adjacent reflective protrusions 3 within adjacent spiral reflective rings is the same.

[0021] like Figure 1 As shown in this example, preferably, the shape of the reflective protrusion 3 is spherical or frustum tetrahedral.

[0022] Specifically, when the reflective protrusion 3 is a four-sided frustum, all four sides of it face the strip lamps 2 on the four sides of the light guide plate 1, thus forming an effective reflection.

[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
