Strip-shaped sleeve of modular lamp box and light-emitting module

Abstract

The invention relates to a strip-shaped sleeve of a modular lamp box and a light-emitting module. The strip-shaped sleeve comprises a support shell, front modules, bus connectors and a face cover, wherein the support shell is composed of a shell base plate, lamp grooves and fixing clamping grooves at the rear side of the base plate, connecting convex blocks on the shell, and clamping grooves in the shell; the bottoms of the lamp grooves at the rear side of the base plate comprise lamp holes and first open holes in the bottoms of the lamp grooves are also arranged, and open holes in the shell are arranged among the lamp grooves at the rear side of the base plate; and the front modules are horizontally mounted on the front side of the shell base plate, so that electric connectors on the front modules are arranged in the first open holes in the bottoms of the lamp grooves, the bus connectors are mounted in the open holes of the shell, and the face cover is mounted on the front side of thesupport shell. The light-emitting module comprises the strip-shaped sleeve and also comprises lamp strips, the lamp strips are mounted in the lamp grooves at the rear side of the base plate, so thatlight sources are arranged in the lamp holes in the bottoms of the lamp grooves, and electric connectors on the lamp strips are in straight insertion connection with the electric connectors on the front modules. The strip-shaped sleeve and the light-emitting module provided by the invention have the advantages that the strucutre is simple, the heat dissipation effect is good, the mounting and maintenance are convenient, etc.

Description

technical field [0001] The invention relates to the field of light boxes, in particular to a strip kit and a light emitting module 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, ...

AI Technical Summary

Problems solved by technology
