Modularized lamp box

Abstract

The invention relates to a modularized lamp box. The modularized lamp box is formed by splicing a plurality of light emitting modules in arrays; each light emitting module comprises a backlight unit,a box body and a power supply; the plurality of the backlight units are installed on the box body installing surface on the front side of the box body in an array and are connected with the power supply in a power supplying manner; each backlight unit consists of an array lens shell which is also used for installing a light source module, a mask and the light source module; the mask is installed on the front side of the array lens shell and is connected with a shell connecting tongue-and-groove through a mask connecting tongue-and-groove; the light source module is installed on the rear side of the array lens shell, so that a light source on the front side of the light source module is placed in a light emitting port of a lens and is fixed by a first bolt base bolt on the rear side of theshell; each backlight unit is fixed with the box body installing surface on the front side of the box body through a second bolt base bolt on the rear side of the shell; after the plurality of light emitting modules are fixed by an installing mechanism on the rear side of the box body after being spliced in the array. The modularized lamp box provided by the invention has the advantages of uniformlight emitting, simple structure, convenience in installation, repair, maintenance and the like.

Description

technical field [0001] The invention relates to the field of light boxes, in particular to a modular light box. Background technique [0002] As we all know, light boxes have a wide range of applications, which involve construction, industry, lighting, civil, commercial, medical, advertising, transportation and other special purposes. Among them, the application in the field of advertising communication is the most widely used, mainly including panel light boxes, cloth light boxes, crystal ultra-thin light boxes and plastic ultra-thin light boxes, mirror induction ultra-thin light boxes, magnetic suction ultra-thin light boxes, dynamic light boxes, etc. [0003] For light boxes in the field of advertising communication, there are mainly two structures: one is a light box with a side-entry backlight structure, which is mainly composed of a light guide plate and a light source. The light source is installed on the side of the light guide plate and at the bottom of the light gu...

Problems solved by technology

[0003] For light boxes in the field of advertising communication, there are mainly two structures: one is a light box with a side-entry backlight structure, which is mainly composed of a light guide plate and a light source. The light source is installed on the side of the light guide plate and at the bottom of the light guide plate There are engraved or printed light guide points. Due to the limitation of light guide distance, the light box with side-type backlight structure is suitable for products with a small light-emitting area, such as small-sized decorative paintings, window displays, flat panel lighting, etc. However, There are light sources on both sides or around the light guide plate, 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.
