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. |
其他摘要 | 封装的发光器件包括基板,基板上的固态发光器件,基板上的第一大致环形透镜,并且相对于固态发光器件限定腔并具有第一折射率,第二透镜至少部分地位于由第一透镜形成的腔内,并且具有不同于第一折射率的第二折射率。第二折射率可以高于第一折射率。透镜可以安装在基板上和/或可以通过分配和固化液体密封剂材料来形成。 |
