Second, the characteristics and types of outdoor light box advertising
Light box advertising is also called "light box poster" or "night light poster". Foreign countries call it "semi-permanent" street art, and outdoor light box advertising is different from other types of advertising. Its characteristics are as follows:

Third, the light box manufacturing process
The manufacturing and installation process of light box mainly includes hoisting, fixing, assembling, installing test tubes, installing pictures and making waterproof structure.
(A) the production of light box shape structure
The outer contour is the main frame of the light box, which determines the appearance modeling and structural durability of the light box.
1. The main frame is made of 600*600mm square steel tube, which is covered with stainless steel plate.
2. The interior of the light box frame is steel structure, and the main material of the steel structure frame is 400*400mm square iron pipe, and the connection mode is welding.
(2) Auxiliary structure of light box part
The auxiliary structure of light box is the secondary structure frame of light box, which is mainly used to fix ballast, time controller, capacitor, lamp tube, light box cloth and so on.
(Attachment: After the light box main structure, light box auxiliary structure, functional parts and other frame structures are welded, they should be manually polished and derusted to remove welding slag and sprayed with antirust paint. )
