发明名称 METHOD OF MAKING A LIGHT EMITTING DEVICE HAVING A MOLDED ENCAPSULANT
摘要 Disclosed herein is a method of making a light emitting device having an LED die and a molded encapsulant made by polymerizing at least two polymerizable compositions. The method includes: (a) providing an LED package having an LED die disposed in a reflecting cup, the reflecting cup filled with a first polymerizable composition such that the LED die is encapsulated; (b) providing a mold having a cavity filled with a second polymerizable composition; (c) contacting the first and second polymerizable compositions; (d) polymerizing the first and second polymerizable compositions to form first and second polymerized compositions, respectively, wherein the first and second polymerized compositions are bonded together; and (e) optionally separating the mold from the second polymerized composition. Light emitting devices prepared according to the method are also described.
