Description

Technical Field

[0001] The utility model relates to a light guide structure, in particular to a structure for optimizing a bright spot at a light end of light introduction. Background Art

[0002] like Figure 1 The existing light guide structure is that an LED lamp 3-3 is arranged at one end of the light guide 3-4, and an inner light distribution mirror 3-1 is placed on the light guide 3-4, and a black decorative ring 3-2 is arranged around the inner light distribution mirror 3-1.

[0003] In addition, the current conventional design of the light guide has a small shielding area and no buffer area, resulting in the light inside the light guide not being evenly mixed before hitting the light guide teeth, resulting in bright spot defects. Utility Model Content

[0004] The purpose of the utility model is to provide a structure for optimizing the bright spot of the light end of the light introduction so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A structure for optimizing the bright spot of light end of light introduction comprises a conventional light guide pattern, a stripe pattern and a light guide, wherein the surface of the light guide is integrally formed with a plurality of conventional light guide patterns and a plurality of stripe patterns, and the conventional light guide pattern and the stripe pattern are arranged in an alternating manner.

[0007] As a further solution of the utility model: the angle and tooth height of the stripe pattern are greater than those of the conventional light-guiding pattern.

[0008] As a further solution of the utility model: the conventional light guide pattern is a light guide tooth whose one side of the light guide is processed into a tooth shape.

[0009] As a further solution of the utility model: one end of the light guide faces the LED lamp.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. It can optimize the lighting uniformity of the light guide light-emitting form;

[0012] 2. It can greatly save the space of lamps and provide feasibility for compact lamps. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the prior art.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 2 In an embodiment of the utility model, a structure for optimizing the bright spot of the light end of light introduction includes a conventional light guide pattern 4-1, a strip pattern 4-2, an LED lamp 4-3 and a light guide 4-4, and the surface of the light guide 4-4 is integrally formed with a plurality of conventional light guide patterns 4-1 and a plurality of strip patterns 4-2, and the conventional light guide pattern 4-1 and the strip pattern 4-2 are staggered.

[0017] The angle and tooth height of the strip pattern 4-2 are greater than those of the conventional light-guiding pattern 4-1.

[0018] The conventional light guide pattern 4-1 is a light guide tooth whose one side of the light guide 4-4 is processed into a tooth shape.

[0019] One end of the light guide 4 - 4 faces the LED lamp 4 - 3 to receive light.

[0020] According to light tracking, the light guide teeth that produce bright spots are removed, and a strip pattern is placed in the original position of the light guide teeth. Parameters such as the pattern angle and tooth height are changed to make its brightness basically the same as other places, so as to achieve a consistent lighting effect.

[0021] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0022] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
