Light source module

Abstract

The invention relates to a light source module, comprising a light guide plate; the light guide plate comprises at least one light incident face, a light emerging face adjacent to the light incident face, and a bottom surface opposite to the light emerging face and adjacent to the light incident face; and the light source module further comprises a reflecting assembly located at the light emerging face, at least one luminous assembly arranged at the light incident face. The light source module provided by the invention has the beneficial effect that the light guide plate and the luminous assembly are used for providing a even area light source, and the light emerging face of the light guide plate is further provided with a dodging film, thereby the emergent light evenness of the light source module is promoted, and bright spots generated when light guide particles scatter light rays can be further avoided.

Description

technical field [0001] The present invention relates to a light source module, in particular to the structure of the light source module. Background technique [0002] Today, when commercial activities are very frequent, in order to promote the company's products or the company itself, advertising has become one of the methods of sales or publicity, and advertising is a language, text, images, etc. on the media to achieve a certain goal.

Problems solved by technology

[0004] However, the installation positions of the lamp tubes 52 greatly affect the lighting effect of the light source module 50. If the distance between the lamp tubes 52 is too long, the advertising layer 540 cannot be evenly lit, for example, in the lamp tube The brightness of the advertising layer 540 directly in front of 52 is too bright and produces a glare effect so that the viewer cannot read, while the brightness of the advertising layer 540 correspondingly arranged between the two light tubes 52 is insufficient, and the user must be very close to the advertising layer 540 to read. The message to be conveyed by the advertisement layer 540 can be read; in this way, not only the effect of the advertisement is greatly reduced, but also the viewer is troubled while watching
