Abstract

The invention relates to the technical field of lamp box illumination equipment, in particular to a stand column type lamp box structure which comprises a cuboid shaped lamp box body, wherein an observation hole is formed in the side wall of the lamp box body; a drawing board is detachably connected at the observation hole; through holes are formed in the top and bottom of the lamp box body; a convex mirror is arranged at the top of the lamp box body, and the mirror surface of the convex mirror is donwards; a flexible support plate is arranged at the bottom of the lamp box body; a bulb is arranged above the support plate; a plurality of reflective lenses are fixedly arranged on the upper surface of the support plate; a telescopic rod filled with thermal expansion media is arranged at the vertical corner in the lamp box body; the upper end of the telescopic rod is connected with the lamp box body; sliding blocks are arranged at the lower end of the telescopic rod; wedge blocks in sliding fit with the sliding blocks are fixedly arranged on the lamp box body; an elastic rod is arranged between the two opposite sliding blocks, and the two opposite sliding blocks are positioned on the diagonal line at the bottom of the lamp box body; and the elastic rod is connected with the lower surface of the support plate. With adoption of the scheme, the problem in the prior art that display atthe upper part of the drawing board of the stand column type lamp box is darker is solved.

Description

technical field [0001] The invention relates to the technical field of light box lighting equipment, in particular to a column light box structure. Background technique [0002] The column-type light box made by 3D printing technology has better structural integrity. Install light-transmitting picture boards on each display surface of the light box, install light bulbs inside the light box, and illuminate the picture boards with the light source sent by the light bulbs, so that the light box looks very beautiful. The bulbs installed in the light box are generally located in the middle of the light box, but in this way, the position on the drawing board with a smaller distance from the light bulb will appear particularly bright, while the position with a larger distance from the light bulb will appear darker. Make the picture of the whole drawing board look not very coordinated. Moreover, when the light bulb is in use, the light bulb will generate a large amount of heat. Th...
