Description

Technical Field

[0001] The utility model relates to the technical field of light boxes, in particular to a new type of high-brightness dynamic light box. Background Art

[0002] Dynamic light boxes are light boxes that achieve dynamic visual effects by alternately flashing different lights. Dynamic light boxes have strong visual impact and good brightness effects, especially in dark environments, they can attract the audience's attention and create a visual impact. At present, dynamic light boxes are widely used for display and publicity in places such as billboards, trademarks, and architectural decorations.

[0003] Structurally, a dynamic light box may include components such as an outer frame, a light source, a panel, an inverter, and a control system. The outer frame protects the internal components and improves the aesthetics; the light source, such as an EEFL lamp, provides stable and efficient lighting; the panel is used to display the content; the inverter converts AC power into DC power; and the control system is responsible for controlling the dynamic effects of the light box, such as the flashing changes, color gradients, and brightness adjustment of the LED light strips; currently, when the LED light strips of a dynamic light box are in use, they are mostly installed and fixed to the inner wall of the dynamic light box by bolts or other connection methods. When the LED light strip fails, maintenance personnel need to open the light box and take out the lampshade, light guide plate and other structures in turn before replacing the LED light strip. This design makes it very inconvenient to replace the LED light strips of the dynamic light box. In view of this, we propose a new type of high-brightness dynamic light box. Utility Model Content
