Assembled modular lamphouse

Abstract

The invention relates to an assembled modular lamphouse, which is formed by assembling a plurality of light emitting modules according to arrays, wherein each light emitting module comprises back light units, a box body and a power supply; a plurality of back light units are mutually spliced and arranged at a box body installing surface at the front side of the box body according to arrays, and are electrically connected with the power supply; each back light unit consists of an array lamp hole module, a light dispersion surface cover and a light source module; the array lamp hole module is also used for installing the light source module; the light dispersion surface cover is arranged at the front side of an array lens module; a surface cover connecting tongue and groove is in direct insertion connection with a base connecting tongue and groove; the light source module is arranged at the back side of the array lamp hole module, so that the light source at the front side of the light source module is positioned in a lamp hole formed in the base plate, and is fixed by a first screw base post at the back side of the base plate through screws. The assembled modular lamphouse has the advantages that the light emitting is uniform; the structure is simple; the installation and the maintenance are convenient; the requirement of outdoor application is met.

Description

technical field [0001] The invention relates to the field of light boxes, in particular to an assembled 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 t...

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.
