Abstract: A light-emitting element substrate and a light-emitting element using the same are disclosed. The light-emitting element substrate includes a transparent substrate and an intermediate layer. The transparent substrate has a plurality of microstructures on a surface thereof, top portion of each microstructure is a plane structure, and an adjacent interval between the plane structures is between 0.5 ?m and 2.5 ?m, the plurality of microstructures have gaps therebetween, and the intermediate layer is covered on the plane structures for facilitating production of epitaxial layer. In an embodiment, the gaps of the plurality of microstructures are still reserved when the epitaxial layer is grown on the plurality of microstructures so as to improve light extraction efficiency of the light-emitting element using the light-emitting element substrate.

Abstract: The present invention discloses a substrate structure applicable to a vertical light emitting element and a vertical light emitting element thereof. The substrate structure comprises a transparent substrate and a reflective layer, and the reflective layer is used to improve a focus of a yellow light manufacturing process. The technique is applicable to PSS substrate and the substrate structure is used to produce the vertical light emitting element to increase the light emitting efficiency.

Abstract: The present invention relates to a three-dimensional woven hollow layer-connecting fabric, comprising an upper layer-surface (10) formed by crossing upper ground warp yarns (1), (2) and a weft yarn (3) and a lower layer-surface (11) formed by crossing lower ground warp yarns (4), (5) and a weft yarn (6); the weft yarns (3) and (6) on the upper and lower layer-surfaces are also crossed with poil warps (7), (8) besides ground warp yarns (1), (2) and (4), (5) on their own layer-surface; the spatial walking direction of poil warps (7), (8) woven from one layer-surface to another is opposite to the weft-inserting direction of the fabric. The framework feature of the composite layer-connecting fabric of the present invention is distinct, and the vertical support function of poil warps between two layer-surfaces is good. The spatial structure of the layer-connecting fabric is varied in conformation, easy to design and adapted to produce on a large scale.
