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

Abstract

The invention relates to an arc-shaped modular light box. The arc-shaped modular light box is composed by a plurality of long-strip-shaped backlight modules which are mutually spliced vertically or transversely, and connected with a power source in a powered mode; each backlight module is composed of a long-strip-shaped supporting shell, a mask and a light source module; the supporting shells arealuminum profiles constituted by shell bottom plates, fixing clamping grooves in the shells, connecting convex blocks on the shells, and screw clamping grooves in the shells, and the shell bottom plates are provided with a plurality of light holes which are evenly distributed in an arrayed mode; the masks are sectional materials with U-shaped sections, and are mounted on the front sides of the supporting shells, and clamping devices on side plates are connected with the connecting convex blocks on the shells in a clamped mode; and the light source modules are mounted on the rear sides of the shell bottom plates, and light sources are placed in the light holes in the shell bottom plates and fixed through the screw clamping grooves in the shells. The arc-shaped modular light box has the advantages of being uniform in light emitting, simple in structure, convenient to mount and maintain and the like.

Description

technical field [0001] The invention relates to the field of light boxes, in particular to an arc-shaped 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 module structure, which is mainly composed of a light guide plate and a light source. The light source is installed on the side of the light guide plate. A light guide point. Due to the limitation of light guide distance, the light box with side-type backlight module structure is suitable for products with a small light-emitting area. Commonly used in small-scale decorative paintings, window displays, panel lighting, etc. However, the light sources arran...
