Lens light scattering plate, backlight module and modular lamp box

Abstract

The invention relates to a lens light scattering plate, a backlight module and a modular lamp box. The lens light scattering plate is integrally composed of a base plate, a plurality of lamp holes, spherical structures, fences, a plurality of first screw hole foundation columns, a plurality of second screw hole foundation columns and convex blocks, wherein the multiple lamp holes are laid out in one side of the base plate according to arrays, the spherical structures are sunken in the bottoms of the lamp holes, the fences are arranged around the peripheries of the lamp holes, the multiple first screw hole foundation columns are located within the ranges of the fences and arranged in the mode of keeping a certain distance, the multiple second screw hole foundation columns are located on theouter sides of the fences and arranged in the mode of keeping a certain distance, and the convex blocks are located on the other side of the base plate and arranged corresponding to the lamp holes; microstructures are arranged at the tops of the convex blocks on the base plate; the backlight module comprises the lens light scattering plate, and further comprises a modular backlight module body constituted by a box body unit and a light source module; and the modular lamp box is constituted by the backlight module, and the large-specification modular lamp box can be spliced. The advantages that the structure is simple, mounting and maintaining are convenient, and no obvious dark line exists are achieved.

Description

technical field [0001] The invention relates to the field of light boxes, in particular to a lens diffuser plate, a backlight module and a modularized light box. Background technique [0002] With the development of the global economy, under the new situation of global urbanization and the continuous advancement of smart cities, people have put forward higher requirements for vision, and the development of various publicity and display terminals has been unprecedentedly high. As the mainstream carrier of publicity and display, the light box is widely used by people because of its beautiful and exquisite, simple and generous, and strong display power. At present, it is developing in the direction of energy saving, environmental protection, green and dynamic; in order to expand the scope of application and enhance the display ability, it also needs to develop in the aspects of modularization, large area and artistic modeling to meet the needs of the future market.
