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

Embodiment Construction

[0023] The technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the backlight module of an arc-shaped modular light box of the present invention.

[0024] The front side and the rear side described in this embodiment are based on the front side and the rear side described in the accompanying drawings.

[0025] Embodiments of the backlight module of the arc-shaped modular light box of the present invention, such as Figure 1 to Figure 4As shown, the backlight module is composed of a strip-shaped support housing 1, a mask 2 and a light source module 3. The support housing 1 is a kind of housing bottom plate 11 connected to the rear side edges of the housing bottom plate 11. The fixed slots 12 on the housing and the connecting projections 14 on the housing with clamping positions on both sides of the housing base plate 11 and the housing base plate 11 on whic...

Abstract

The invention relates to a backlight module of an arc-shaped modular lamp box. A supporting shell is an aluminum profile which is composed of a shell bottom plate, fixing clamping grooves in the shell, connecting lugs on the shell and screw clamping grooves in the shell, and a plurality of lamp holes which are uniformly distributed in an array are formed in the shell bottom plate; a mask is a sectional material with a U-shaped section, the mask is arranged on the front side of the supporting shell, and a clamping device on the mask is connected with the connecting lugs on the shell in a clamped mode; a light source module is arranged on the rear side of the shell bottom plate, so that light sources are arranged in the lamp holes in the shell bottom plate, and open holes in the light sourcemodule are fixed through the screw clamping grooves in the shell. The backlight module can not only be used for being spliced into the lamp box with large-area light emitting, but also can be splicedinto a modular lamp box with an arc-shaped light-emitting surface, and has the advantages of being uniform in light emitting, simple in structure, attractive in appearance, convenient to install andmaintain and the like.

Description

technical field [0001] The invention relates to the field of light boxes, in particular to a backlight module of 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 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, the light sources arranged on both sides or around the light guide plate cause dark...
