[0002] Advertising light boxes are a common outdoor advertising display tool. They are composed of a box with a transparent panel and a lighting device installed inside to display advertising content. Advertising light boxes are an effective form of outdoor advertising that can attract the attention of pedestrians and vehicles, increase brand exposure and product sales. Advertising light boxes are durable and waterproof, and are often made of aluminum alloy, stainless steel or special plastic materials.

[0003] In the prior art, a Chinese patent with the authorization announcement number CN209641290U discloses an advertising light box with good sealing performance, which belongs to the field of advertising light boxes.
