Abstract
A light source includes an LED component having an emitting surface, and an optical element having an input surface in optical contact with the emitting surface. The LED component may be or include an LED such as an LED die capable of emitting light at a first wavelength, in combination with a re-emitting semiconductor construction which includes a second potential well not located within a pn junction. The optical element can be an extractor whose shape is converging, diverging, or a combination thereof.
