Abstract

The invention relates to a supporting shell and surface cover for a modular lamp box. The supporting shell is a long-strip-shaped aluminum profile integrally formed by a shell base plate, a pluralityof parallel and uniformly-arrayed lamp grooves formed in the rear side of the shell base plate in the length direction, two parallel fixed clamp grooves formed in the rear side of the shell base platein the length direction, connecting lugs arranged at the edges of the two sides of the shell base plate on the shell with clamping positions and a plurality of clamping grooves formed in the shell base plate in the length direction and provided with groove openings facing forwards. The supporting shell has the advantages of being good in heat dissipation, simple in structure, convenient to manufacture and the like. The surface cover 2 is matched with the supporting shell and is a long-strip-shaped plastic profile with a U-shaped cross section, the long-strip-shaped plastic profile is internally formed by a panel, surface cover side plates protruding backwards at the two sides of the panel and clamping devices arranged on side plate bodies at the rear sides of the surface cover side plates. The surface cover has the advantages of being simple in structure, convenient to manufacture and the like.

Description

technical field [0001] The invention relates to the field of light boxes, in particular to a support shell and a mask of a 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 there...
