Forming method of modular arc-shaped lamp housing

Abstract

The invention relates to a forming method of a modular arc-shaped lamp housing. Firstly, a long strip-shaped support casing used for face cover and lamp strip installation, a face cover arranged at the front side of the support casing, and a lamp strip arranged at the back side of the support casing are used for forming a long strip back light module; the support casing is integrally formed by a casing base plate, a lamp groove formed in the back side of the casing, connecting convex blocks arranged on the casing, and the like; a lamp hole is formed in the bottom of the lamp groove formed in the back side of the casing; a clamp position at the back side of the face cover side plate is clamped and connected with the connecting convex block arranged on the casing; a light source at the frontside of the lamp strip is put in the lamp hole; the wiring end on the lamp stirp is electrically connected with a bus; then, a plurality of long strip back light modules are mutually spliced in the longitudinal direction or transverse direction, and are fixed with the support frame via screw bolts through the fixing clamp grooves; the bus and the power supply are in power supply connection, so that the modular arc-shaped lamp housing is formed. The modular lamp housing formed by splicing according to the method has the advantages that the luminescence is uniform; the structure is simple; theappearance is attractive; the maintenance is convenient.

Description

technical field [0001] The invention relates to the field of light boxes, in particular to a method for forming a modular arc 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 areas ca...

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
