The present invention provides a LED packaging structure, and more particularly to an innovative one designed with blind hole welding device. It at least comprises: a packaging body, which is provided with a wiring substrate; metal layers are separately arranged at both sides for coating the wiring substrate; the metal layers are divided into three portions, i.e. metal layer 1, 2, 3, according to the electrical connection point; a plurality of blind holes arranged at bottom of the wiring substrate, and then connected with metal layer 3; a single or a plurality of LED chips arranged onto the wiring substrate; a colloid coated on the LED chip; the packaging body is welded directly onto the substrate for electrical connection, so that LED chip is highlighted. The blind hole is arranged to facilitate the welding, helping to improve the electrical connection and welding performance. |
