Luminescence module

Abstract

The invention relates to a luminescence module which comprises a light source and a light guiding plate, wherein the light source emits light towards one incident light surface of the light guiding plate; a plurality of linear three-dimensional units are configured on the emergent light surface of the light guiding plate; the reflecting surface of the light guiding plate comprises a plurality of first three-dimensional unit groups and second three-dimensional unit groups; the first three-dimensional unit groups are positioned on the vertical projection position of the reflecting surface corresponding to the linear three-dimensional units, and respectively comprise a plurality of first linear microstructures of the parallel linear three-dimensional units; the second three-dimensional unit groups are positioned in the area except the first three-dimensional unit groups on the reflecting surface and is composed of a plurality of second linear microstructures; the first linear microstructures and the second linear microstructures are different and are both parallel with the linear three-dimensional units and incident light surfaces; one of the perpendicular throw, maximum width and distribution density of the second linear microstructures is in proportion to the distance of the incident light surface and the second linear microstructures. The module can improve the unexpected linear bright fringes of the emergent light surface of the light guiding plate, thus homogenizing the emergent light luminance.

Description

technical field [0001] The invention relates to a light emitting module, in particular to a structure of the light emitting module. Background technique [0002] In the light-emitting module at the present stage, in the light guide plate system containing the microstructure patterns of linear grooves or ridges, a plurality of microstructure patterns of linear grooves or ridges 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 line will display multiple corresponding linear bright lines, resulting in uneven light emission on the light-emitting surface as a whole, and more optical cover sheets must be used to compensate , which consumes a lot of 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 requirements, or at least provide a solution to this defect, it wi...
