Abstract:
1. A method of making a light emitting device, the method comprising: (a) providing an LED package comprising an LED die disposed in a reflecting cup, the reflecting cup filled with a first photopolymerizable composition such that the LED die is encapsulated, and partially polymerizing the first photopolymerizable composition to form a first partially photopolymerized composition, wherein partially polymerizing comprises applying actinic radiation having a wavelength of 700 nm or less; (b) providing a mold having a cavity filled with a second polymerizable composition; (c) contacting the first partially photopolymerized composition and the second polymerizable composition; (d) polymerizing the first partially photopolymerized composition and the second polymerizable composition 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.
