Light diffusing module and lamp box

Abstract

The invention relates to a light diffusing module and a lamp box. The light diffusing module comprises light diffusing module bodies, a module box body and light source modules; each light diffusing module body is constituted integrally by a base plate, light diffusing module lamp holes, sunken spherical structures, screw base columns and protruding blocks, wherein the light diffusing module lampholes are evenly arrayed in the rear side of the base plate in an array mode, the sunken spherical structures are arranged at the bottoms of the light diffusing module lamp holes, the screw base columns are arranged on the light diffusing module body, and the protruding blocks are arranged on the base plate; light diffusing microstructures are arranged on the front sides of the protruding blocks on the base plates; the module box body is composed of a box body supporting face, a box frame, an opening in the box body supporting face, screw holes in the box body supporting face, and fixing devices used for fixing the light source modules and arranged on the rear side of the box body supporting face; and the light diffusing module bodies are mounted on the front side of the box body supporting face in an array mode, the light source modules are mounted on the rear side of the box body supporting face, and the light diffusing module bodies can be spliced in a shadowless mode. The lamp boxis formed by the light diffusing modules in a spliced mode, and obvious concealed lines on the front sides of the light diffusing modules during picture installation are avoided, and thus the market demands are met.

Description

technical field [0001] The invention relates to the field of light boxes, in particular to an astigmatism module and a 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, spiritual civilization and material civilization have been significantly improved, people have put forward higher requirements for vision, and the development of various publicity and display terminals has become more All-time high. As the mainstream carrier of publicity and display, the light box is widely used by people because of its beautiful, exquisite, concise 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...
