Abstract
A light emitting device comprises an LED die, a dome lens encapsulating the LED die, the dome lens having a first outer curved surface, and a photopolymerizable composition disposed on the dome lens. The photopolymerizable composition forms a meniscus lens defined by a second outer curved surface and an inner curved surface, the inner curved surface being in contact with only a portion of the first outer curved surface. The dome lens and the meniscus lens in combination form an elongated dome lens.
