Luminescence module

Abstract

The invention relates to a luminescence module which comprises a light source and a light guiding plate, wherein the light guiding plate comprises incident light surfaces, an emergent light surface and a reflecting surface; the light source emits light towards the incident light surfaces; a plurality of linear three-dimensional units are configured on the emergent light surface in parallel and at intervals; the reflecting surface comprises a plurality of first microstructural net point groups and second microstructural net point groups; the first microstructural net point groups are respectively aligned to the linear three-dimensional units; each first microstructural net point group is composed of a plurality of first net points; the luminance of the first net points influences the variable quantity such as density distribution, depth and calibers, and is in proportion to the distance of the first net points and the first incident light surface; and each second microstructural net point group is composed of a plurality of second net points which are different from the first net points, and the luminance of second net points influences the variable quantity and is in proportion to the distance of the second net points and the first incident light surface. The luminescence module in the invention has the advantages of being capable of improving the unexpected linear bright fringes on the emergent light source of the light guiding plate and homogenizing the emergent light luminance of the emergent light surface of the light guiding plate.

Description

Technical field [0001] The invention relates to a light-emitting module, in particular to the structure of the light-emitting module. Background technique [0002] In the current light-emitting module, the microstructure pattern containing linear grooves or convex strips is in the light guide plate system, and a plurality of linear grooves or convex strip microstructure patterns (such as V or U-shaped) are arranged at intervals on one side. When the light guide plate emits light, the position of the light-emitting surface corresponding to each linear groove or convex strip will show multiple corresponding linear bright lines, resulting in uneven light output on the light-emitting surface. More optical cover sheets must be used to compensate , It is quite costly in material cost and needs to be further improved. [0003] Therefore, if a light-emitting module design can be provided that can meet the above-mentioned needs, or at least provide a solution to this defect, it becomes an ...

Problems solved by technology

When the light guide plate emits light, the position of the light-emitting surface corresponding to each linear groove or convex line will display multiple corresponding linear bright lines, resulting in uneven light emission on the light-emitting surface as a whole. More optical cover sheets must be used to compensate , which consumes a lot of material cost and needs to be further improved
