METHOD FOR MANUFACTURING PHOSPHOR FILM AND METHOD FOR MAKING LED PACKAGE HAVING THE PHOSPHOR FILM |
摘要 |
A method for manufacturing a phosphor film for use in the an LED package, includes following steps: providing a mold comprising a first and a second molding part, the first molding part and the second molding part cooperatively forming a molding chamber, the first molding part defining an opening communicating with the molding chamber; filling a mixture of phosphor particles and a transparent glue into the first opening; moving a piston in the first opening along a direction from the first molding part to the second molding part, thereby pressing the mixture into the molding chamber; solidifying the mixture to form a phosphor film; and removing the phosphor film from the mold. The phosphor film is used to be attached to a top face of an LED chip opposite a substrate on which the LED chip is mounted. |
