Abstract
The present disclosure provides a configuration and technique of fabricating remote phosphor optics (such as lenses) for downconverting LEDs, replacing the prior art solid hemispherical lenses with a novel thin-shell hemispherical lens that can be used with a wide range of encapsulating materials, including low index materials such as air and methyl silicones. The present disclosure further provides a configuration and technique whereby the remote phosphor lenses can be used with an LED array.
