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 polymerizable composition such that the LED die is encapsulated; (b) providing a transparent mold having a cavity filled with a second polymerizable composition; (c) polymerizing the second polymerizable composition to form a second partially polymerized composition, wherein polymerizing the second polymerizable composition comprises applying actinic radiation having a wavelength of 700 nm or less; and (d) inverting the mold to contact the first polymerizable composition and the second partially polymerized composition; (e) polymerizing the first polymerizable composition to form a first partially polymerized composition, wherein polymerizing the first polymerizable composition comprises applying actinic radiation having a wavelength of 700 nm or less.
