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.

A light emitting device, comprising:
- 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 forming 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;
- wherein the dome lens and the meniscus lens in combination form an elongated dome lens.
A light emitting device, comprising:
- an LED die;
- a dome lens encapsulating the LED die, the dome lens having a first outer curved surface;
- and
- a photopolymerized material disposed on the dome lens, the photopolymerized material forming 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;
- wherein the dome lens and the meniscus lens in combination form an elongated dome lens.
A light emitting device, comprising:
- an LED die disposed on a support structure;
- a dome lens encapsulating the LED die, the dome lens contacting the support structure and having a first outer curved surface;
- and
- a photopolymerized material disposed on the dome lens, the photopolymerized material forming a meniscus lens defined by a second outer curved surface and an inner curved surface;
- wherein the photopolymerized material contacts the dome lens along the inner curved surface without contacting the support structure;
- and
- wherein the dome lens and the meniscus lens in combination form an elongated dome lens.
