STRUCTURE OF LIGHT GUIDE PLATE WITH A TUBE MANIFOLD

摘要

The present invention relates to a structure of a light guide plate for backlighting. This structure of a light guide plate includes a flat light guide plate body having a uniform thickness and a wedge-type light receiving unit formed on a side of a light source of the body. In particular, the light receiving unit includes: a plurality of light guide holes which are provided to be elongated from an incident surface to a rear inclined surface along an optical axis direction and are arranged to be parallel to each other; and a tube manifold which includes a plurality of hollow guide tubes, of which the outer surfaces are closely fitted in the inner surfaces of the guide holes and are supported and which integrally correspond to the plurality of guide holes, and of which the upper end and the lower end are bent towards the body on the rear side thereof and are pressed and coupled to the upper surface and the lower surface of the light receiving unit, respectively. The structure of the light guiding plate according to the present invention may reduce a loss by light spreading and improve illuminance characteristics. Meanwhile, the tube manifold may be pressed and coupled to the light receiving unit.
