Description

Technical Field

[0001] The utility model relates to the technical field of light guide strips, in particular to a light uniforming pattern structure at the end of a light guide strip. Background Art

[0002] In the field of automotive lighting, LED light sources are gradually replacing the original incandescent bulbs. Considering the design and the trend driven by advanced automobile manufacturers, the use of light guides is increasing day by day; in contrast, today's commercial light strips are often based on dense arrangement of direct-down LEDs, or use side-input light sources with Vcut structures as a mechanism to destroy total reflection. However, with the trend of decreasing LED numbers, direct-down can no longer meet cost requirements.

[0003] However, when using the light guide strip, the total reflection of light on the end surface of the light guide strip is likely to cause bright spots, which in turn causes different vertical distances between the central axis of the straight light guide strip and the surface of the illuminated object, resulting in different illuminances on the surface of the illuminated object, resulting in an uneven illumination surface in visual perception.

[0013] Through the above technical solution, the mounting column is not only conducive to improving the stability of the light guide strip body after installation, but also convenient for connecting the light source through the mounting column.

[0014] Preferably, a light-distributing pattern body is disposed at the rear side of the output end, and the light-distributing pattern body is generally provided in a plurality of groups, which are equidistantly arranged at the rear side of the output end.

[0015] Through the above technical solution, when the refracted light passes to the output end, under the action of multiple groups of light-evening pattern bodies, the light is refracted to the invisible area, thereby improving the problem of lighting the bright spot at the output end, and then achieving uniform lighting effect at all viewing angles of the light guide, and improving the overall uniformity after reflection and refraction.
