Abstract: Disclosed is a method for manufacturing white light-emitting diodes (white LEDs) which is capable of manufacturing white LEDs having a superior and uniform quality and a slim structure while simplifying the manufacturing process, thereby reducing the manufacturing costs and time, and achieving a considerable improvement in the yield of those white LEDs. The method involves the steps of mixing a fluorescent dye, adapted to convert blue light into white light, with molding compound powder, thereby preparing a mixture, subjecting the mixture to a desired temperature and a desired pressure, thereby shaping the mixture to have a desired shape, simultaneously transfer-molding the shaped mixture on the blue-light emitting diode chips, thereby forming a molded product, and dicing the molded product into individual white LEDs. Since the method of the present invention eliminates use of a potting process used in conventional methods, it can manufacture white LEDs having a slim structure.
