    摘要： An LED chip encapsulation process includes the steps of (a) forming a fluorescent member by injection molding to encapsulate an LED chip; (b) hardening the fluorescent member; (c) forming a transparent dome to embed and encapsulate the LED chip and the fluorescent member; and (d) securing the dome and the substrate together to finish a packaging of the LED chip. Shape of the fluorescent member disposed on the LED chip can be controlled precisely, thereby increasing quality and color uniformity of the produced LED chip. Alternatively, the LED chip is a remote LED chip and step (a) is replaced by forming a plastic member to encapsulate the LED chip and forming a fluorescent member on the top of the plastic member by injection molding.

    摘要： The present invention provides a bioactive, small-diameter (typically less than 6 mm in internal diameter) vascular graft prosthesis, and is a textile conduit preferably manufactured using a novel electrospinning perfusion methodology. One preferred embodiment is a nanofibrous biocomposite textile conduit which comprises a prepared liquid admixture of polyester (Dacron), a biodurable implantable synthetic polymer, and Type IV collagen, an extracellular matrix protein. This prepared admixture and blending of diverse fibrous matter is utilized in a novel electrospinning perfusion process to form a small-diameter (less than 6 mm) fabricated textile conduit, a discrete article of manufacture, which then serves as an antecedent tangible workpiece for a subsequently-made prosthetic vascular graft construct.
