Description

Technical Field

[0001] This utility model relates to a display lightbox, specifically an adjustable light angle display lightbox, belonging to the field of lightbox equipment technology. Background Technology

[0002] A lightbox is a light source device that uses light to illuminate patterns or translucent panels in front of it. It is commonly used as an advertising display, outdoor billboard, sign, etc., and is widely used in public places such as bus stops, exhibition halls, train stations, and airports, primarily for displaying advertising prints. Existing lightboxes generally consist of a back panel, light source, frame, and curtain, with the frame being a fixed structure.

[0003] The authorized patent with publication number CN207977077U discloses a display lightbox, which relates to the field of lightbox equipment technology. It includes: a vertically erected lightbox body with reflective strips on the left and / or right outer walls of the lightbox body; and a frame fixed to the bottom of the lightbox body. However, the above device does not have a light angle adjustment structure and cannot adjust the angle of light illumination according to needs. When displaying, the lightbox needs to be adjusted according to the surrounding environment and the displayed pattern to match the angle of the light in order to improve the display effect. At the same time, the height of the lightbox needs to be changed according to the display site and environment.

[0004] Therefore, we propose a display lightbox with adjustable lighting angle. Utility Model Content
