AI Technical Summary

Technical Problem

Existing advertising light boxes have complex structures, making it difficult to flexibly change the displayed content. The double-sided light transmission problem causes overlapping shadows, and the built-in power supply is inconvenient to assemble and the wiring is easily clipped and worn.

Method used

It adopts a plug-in connection structure for light box components and lamp holder components, and uses male and female conductive plates to achieve rapid power supply. Combined with aluminum frame and screw connection, it simplifies the assembly process.

Benefits of technology

It enables convenient assembly, avoids wiring clips, reduces costs, improves light transmission and image clarity, and extends service life.

Abstract

This utility model proposes a portable double-sided lightbox, including a lightbox assembly and a lamp holder assembly. The lightbox assembly includes a lightbox frame, a light guide plate, a light-diffusing film, a display component, a transparent panel, and a light-emitting component. The light guide plate is placed at the center of the lightbox frame, the light-diffusing film is attached to both sides of the light guide plate, the transparent panel is placed on both sides of the light guide plate, the display component is placed between the light guide plate and the transparent panel, and the light-emitting component faces the light guide plate. Symmetrical male conductive plates are provided at both ends of the bottom side of the lightbox frame, and the male conductive plates are electrically connected to both ends of the light-emitting component. The lamp holder assembly includes a base, a circuit board, and a power supply assembly. The base has a mounting slot for inserting the lightbox assembly, and the circuit board and power supply assembly are located inside the base. Symmetrical female conductive plates that mate with the male conductive plates are provided at both ends of the mounting slot, and the power supply assembly is electrically connected to the female conductive plates through the circuit board. In this application, the insert connection structure of the lightbox assembly and the lamp holder assembly, combined with the corresponding conductive plate structure at their connection points, enables rapid connection and power-on after assembly, avoiding clamping or wear caused by external wiring.
