Abstract:
1. A vertical stacked light emitting structure, comprising: a substrate body; a first light-emitting unit including a plurality of first LED bare chips stacked on top of one another and electrically connected to the substrate body, wherein the bottommost one of the first LED bare chips is disposed on the substrate body, the topmost one of the first LED bare chips is electrically connected to the substrate body through two first conductive wires, and each first LED bare chip has a first positive pad and a first negative pad; a light-guiding unit including at least one glass light-guiding body that is made of a glass material to form a prefabricated glass light-guiding plate disposed on the topmost first LED bare chip; and a second light-emitting unit including a plurality of second LED bare chips stacked on top of one another and electrically connected to the substrate body, wherein the bottommost one of the second LED bare chips is disposed on the top surface of the prefabricated glass light-guiding plate and electrically connected to the substrate body through two second conductive wires, and each second LED bare chip has a second positive pad and a second negative pad; wherein both the first positive pad and the first negative pad of the topmost first LED bare chip are disposed on the top surface of the topmost first LED bare chip and between the topmost first LED bare chip and the prefabricated glass light-guiding plate, and both the second positive pad and the second negative pad of the bottommost second LED bare chip are disposed on the bottom surface of the bottommost second LED bare chip and between the bottommost second LED bare chip and the prefabricated glass light-guiding plate.
