Abstract

A light source, includes an LED emitter and a meniscus lens having a hollow cavity in which the LED emitter is disposed. The meniscus lens is in exemplary embodiments hyperhemispheric, and it produces a high quality optical image of the LED emitter. The cavity of the lens is filled with air, such as terrestrial atmosphere, inert gas, or vacuum.
