| 1. A light source, comprising:
a) an LED component comprising a first potential well located within a pn junction and a second potential well not located
within a pn junction, the component having an emitting surface; and
b) an optical element including a base, an apTex, and a side joining the base and the apex, wherein the base is optically
coupled to and mechanically decoupled from the emitting surface.
