| 英文摘要 | A packaged light emitting device includes a substrate, a solid state light emitting device on the substrate, a first generally toroidal lens on the substrate and defining a cavity relative to the solid state light emitting device and having a first index of refraction, and a second lens at least partially within the cavity formed by the first lens and having a second index of refraction that is different from the first index of refraction. The second index of refraction may be higher than the first index of refraction. The lenses may be mounted on the substrate and/or may formed by dispensing and curing liquid encapsulant materials. |
