Light scattering suite of modularized lamp box

Abstract

The invention relates to a light scattering suite of a modularized lamp box. The light scattering suite comprises an array cavity shell and a face cover, wherein the array cavity shell is provided with a light source module; the array cavity shell is integrally composed of a plurality of basin-shaped cavities, lamp holes, a fence, a first screw base column, a second screw base column and a shell connecting rabbet, wherein openings of the basin-shaped cavities face the front, the basin-shaped cavities are spliced in an array, the lamp holes are formed in the rear sides of the bottoms of the basin-shaped cavities and run through the front parts and the part parts, the fence is arranged on the rear side of the shell, the first screw base column is arranged on the rear side of the shell, and the second screw base column is arranged on the rear side of the shell. The first screw base column on the rear side of the shell is flush with the rear side faces of the basin-shaped cavities, and thesecond screw base column on the rear side of the shell is flush with the fence on the rear side of the shell. The face cover comprises a panel and an annular panel connecting rabbet which is arrangedon the rear side of the periphery of the panel and provided with a step structure. The face cover is installed on the front side of the array cavity shell, and is in direct inserted connection with the shell connecting rabbet through the panel connecting rabbet. The light scattering suite can shape a point light source and adjust the point light source for planar light emitting, and has the advantages of being uniform in light emitting, simple in structure, convenient to install and maintain and the like.

Description

technical field [0001] The invention relates to the field of light boxes, in particular to an astigmatism kit of a modular light box. Background technique [0002] As we all know, there are two types of mainstream advertising light box structures: one is a light box with a side-type backlight structure, which is mainly composed of a light guide plate and a light source. Due to the limitation of light guide distance, the light box with side-type backlight structure is suitable for products with small light-emitting area, such as small-sized decorative paintings, window displays, flat panel lighting, etc. However, the two sides of the light guide plate Or there are light sources around, so that there are dark areas caused by the light source body on both sides or around the light guide plate, and shadowless splicing cannot be realized. The other is a light box with a direct backlight structure, which is mainly composed of a panel, a light source and a box body. The panel is i...

[0002] As we all know, there are two types of mainstream advertising light box structures: one is a light box with a side-type backlight structure, which is mainly composed of a light guide plate and a light source. Due to the limitation of light guide distance, the light box with side-type backlight structure is suitable for products with small light-emitting area, such as small-sized decorative paintings, window displays, flat panel lighting, etc. However, the two sides of the light guide plate Or there are light sources around, so that there are dark areas caused by the light source body on both sides or around the light guide plate, and shadowless splicing cannot be realized

The other is a light box with a direct backlight structure, which is mainly composed of a panel, a light source and a box body. The panel is installed on the front side of the box body, and the light source is installed on the back side of the box body. Therefore, the thickness of the light box of the direct-type backlight structure is much larger than that of the side-type backlight unit. Because it has the advantages of high brightness and strong controllability of the light source, the application of the direct-type backlight unit is extremely wide, such as Advertising light boxes, signboard light boxes, signboard light boxes and window light boxes, etc. However, the box of the direct-down backlight unit is surrounded by opaque box walls, and serious shadows will appear between the boxes after splicing. Unable to achieve shadowless splicing

It can be seen from the above that the current mainstream advertising light boxes are limited to small-format light boxes. Therefore, the existing large-format advertising in the field of outdoor advertising communication is still stagnant in the four mainstream outdoor carriers of inkjet advertising, three-sided advertising, LED display advertising and luminous character advertising.
