Abstract: A light emitting diode (LED) package structure includes a glass substrate, conductive through holes, active elements, an insulating layer, LEDs and pads. The glass substrate has an upper surface and a lower surface. The conductive through holes penetrate the glass substrate and connect the upper and the lower surfaces. The active elements are disposed on the upper surface of the glass substrate and electrically connected to the conductive through holes. The insulating layer is disposed on the upper surface and covers the active elements. The LEDs are disposed on the insulating layer and electrically connected to at least one of the active elements. The pads are disposed on the lower surface of the glass substrate and electrically connected to the conductive through holes. A source of at least one active elements is directly electrically connected to at least one of the corresponding pads through the corresponding conductive through hole.

Abstract: The present invention discloses a food slicing device. In the present invention, the opening of the horizontal shell disposed horizontally is a material output port; a material-input tube is disposed on the upper part of the shell, and the material-input tube extends upward to form a material-input port; a cutter unit with the same direction to the opening disposed inside the horizontal shell; the rotating shaft protrudes out of the bottom of the shell; a protective cover is disposed on the material output port, whose ring is inserted in the material output port, and the top portion of said protective cover extends outward to form a tongue portion for covering up the opening of said material output port of the shell. So the problem that fingers of consumer are injured accidentally by rotating blade of the cutter is solved.
