Abstract:
A method for manufacturing white light-emitting diodes adapted to convert a blue light emitted from blue light-emitting diode chips into white light using a fluorescent dye, each of the blue-light emitting diode chips being mounted on a printed circuit board or a lead frame while being bonded to the printed circuit board or the lead frame by a conductive or non-conductive adhesive and having electrodes electrically connected with a circuit pattern plated on the printed circuit board or the lead frame, comprising the steps of:mixing the fluorescent dye 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.
