Abstract

The invention relates to a long-strip-shaped backlight unit and a lamp box. The long-strip-shaped backlight unit comprises a plurality of lens modules, a long-strip-shaped shell body and long-strip-shaped light source modules; the lens modules are integrally formed by lens module base plates, convex blocks, lens module light inlets, spherical structures and lens module connecting mechanisms, wherein the convex blocks are uniformly arranged on one sides of the lens module base plates in an array mode, arranged on the lens modules and are protruded and tapering; the lens module light inlets areformed in the tops of the convex blocks on the lens modules; the spherical structures are concaved towards the other sides from the bottoms of the lens module light inlets; the lens module connectingmechanisms are arranged on the two sides of the lens module base plates; the multiple lens modules are fixedly installed on the supporting surface of a supporting plate; the long-strip-shaped light source modules are installed in lamp grooves in the shell body on the other side of the supporting surface of the supporting plate; and light sources of the long-strip-shaped light source modules are enabled to be placed in the lens module light inlets of the lens modules. According to the long-strip-shaped backlight unit and the lamp box, shadowless splicing of the long-strip-shaped backlight unitcan be realized, a picture of the lamp box formed by splicing the long-strip-shaped backlight unit cannot appear obvious dark lines, and thus the market demand is met.

Description

technical field [0001] The invention relates to the field of light boxes, in particular to a strip-shaped backlight module and a light box. Background technique [0002] With the development of the global economy, under the new situation of global urbanization and the continuous advancement of smart cities, spiritual civilization and material civilization have been significantly improved, people have put forward higher requirements for vision, and the development of various publicity and display terminals has become more All-time high. As the mainstream carrier of publicity and display, the light box is widely used by people because of its beautiful, exquisite, concise and generous, and strong display power. At present, it is developing in the direction of energy saving, environmental protection, green and dynamic; in order to expand the scope of application and enhance the display ability, it also needs to develop in the aspects of modularization, large area and artistic m...
