Backlight source of modular lamp box and light-emitting module

Abstract

The invention relates to a backlight source and a light-emitting module of a modular lamp box. The backlight source consists of a lens box installed together with a light source module, a panel and the light source module. The lens box comprises a lens box base plate, a lens on the base plate, a lens box wall, a lens box connecting rabbet, a lamp groove in the back side of the base plate, a connecting groove in the lamp groove, first screw base columns and second screw base columns; the panel is arranged on the front side of the lens box and is connected with the lens box connecting rabbet through the panel connecting rabbet in a direct plugging way; the long-strip light source module is mounted in the lamp groove formed in the rear side of the lens box and is fixed through the first screwbase columns and screws; the light-emitting module comprises the backlight source and also comprises a box body, wherein a plurality of backlight sources are mutually spliced and mounted on the frontside mounting surface of the box body according to an array. The backlight source and the light-emitting module have the advantages of being uniform in light emission, simple in structure, convenientto install, repair and maintain and the like.

Description
