Method for forming assembled module lamp box

Abstract

The invention relates to a method for forming an assembled module lamp box. An array lamp hole module which is also installed as a light source module, a lens module and a face cover which are arranged on the front side of the array lamp hole module, and a light source module arranged at the rear side of the array lamp hole module together form backlight units. The array lamp hole module comprisesa substrate, lamp holes in the substrate, a connecting block on the substrate, a first screw base column on the rear side of the substrate and a second screw base column on the rear side of the substrate. A lens light inlet at the rear side of a lens coincides with the lamp holes in the substrate, a face cover connecting tongue-and-groove joint is directly connected with a connecting block on thebase plate in an inserted mode, and a light source on the front side of the light source module is arranged in the lamp holes in the base plate; the plurality of backlight units are mutually assembled and mounted on a box body mounting surface on the front side of the box body according to an array, and the backlight units are in power supply connection with a power supply to form light emittingmodules; and the plurality of light-emitting modules are assembled in an array to form the assembled module lamp box. The module lamp box is assembled according to the method and has the advantages ofuniform light emitting, simple structure, convenience in installation and maintenance and the like.

Description

technical field [0001] The invention relates to the field of light boxes, in particular to a method for forming an assembled modular light box. Background technique [0002] As we all know, light boxes are widely used, and it involves the construction field, industry field, business field, medical field, advertising communication field, etc., among which the advertising communication field is the most extensive. [0003] At present, there are mainly two types of advertising light box structures: one is a light box with a side-entry backlight structure, which is mainly composed of a light guide plate and a light source. A light guide point. Due to the limitation of light guide distance, the light box with side-type backlight structure is suitable for products with a small light-emitting area. Commonly used in small-scale decorative paintings, window displays, panel lighting, etc. However, light sources are provided on both sides or around the light guide plate, so that the...

AI Technical Summary

Problems solved by technology

However, the cabinet of the direct-lit backlight unit is surrounded by opaque cabinet walls, and serious shadows will appear between the cabinets after splicing. Therefore, shadowless splicing cannot be realized.

As can be seen from the above, the current mainstream advertising light boxes are limited to small format light boxes
