Luminous module

Abstract

The invention relates to a luminous module. The luminous module comprises a light diffusion module and a lamp panel, wherein the light diffusion module is integrally composed of a panel, a plurality of frustum bodies, lamp holes, protective edges and frustum stairs, the multiple frustum bodies are evenly and fully distributed on the rear side of the panel according to an array and protrude backwards, the top faces of the frustum bodies face backwards, the lamp holes are formed in the center parts of the frustum bodies, the protective edges surround all the lamp holes and protrude backwards, each circle of frustum stair is located on the inner side of the corresponding protective edge and is flushed with the top face of the corresponding frustum body, and the lamp panel is mounted within the range of the protective edges; light sources which are arrayed the same as the lamp holes are arranged on the lamp panel; and the lamp panel is fixedly mounted within the range of the protective edges, and thus the light sources are placed in the lamp holes. From the technical features, it can be seen that the multiple frustum bodies on the rear side face of the panel are of an integrated structure which is arrayed according to the array and evenly and fully distributed, any part for shielding light does not exist in the periphery, and thus shadowless splicing can be achieved; and the luminous module is suitable for backlight sources of large display equipment, large lamp boxes and large-area lighting facilities.

Description

technical field [0001] The invention relates to the technical field of backlight sources, in particular to a light emitting module. Background technique [0002] The application of backlight is extremely extensive, not only for TFT-LCD (liquid crystal display), but also widely used in light boxes, lighting and other special display equipment. Among them, the application field of light boxes is the most extensive, which involves the construction field (such as: window , lighting roof, lighting wall, signboard, emergency light source, etc.), industrial fields (such as: film viewer, instrument panel, machine identification, production line process instructions, metering equipment, etc.), lighting field (such as: flat light source, Light source curtains, light source walls, ground light sources, etc.), civil fields (such as: photo frames, decorative paintings, dressing tables, etc.), commercial fields (such as: item array cabinets, guide signs, identification signs, etc.), medic...

AI Technical Summary

Problems solved by technology

Since the diffuser plate is installed on the front side of the box, and the light source is installed on the back side of the box, there is a relatively large distance between the light source and the front side, so the direct-type backlight is relatively thick; at the same time, the box is surrounded by an opaque box. After the body wall is spliced, there will be serious shadows between the cabinets, and it is impossible to achieve shadowless splicing
