Zusammenfassung:	A method and apparatus for collecting and projecting light into a specified target illuminance. A lens may be mounted or otherwise paired to a carrier to form a lens/carrier combination, which may then be mounted to a printed circuit board assembly (PCBA) containing a light emitting diode (LED). The lens/carrier combination may establish an optimum optical relationship between the LED and the lens, such that a predetermined photometric distribution of the LED is collected by the lens, while the remaining photometric distribution of the LED is rejected by the carrier. The lens may include a first pair of opposing surfaces forming a first focus and a second pair of opposing surfaces forming a second focus. The first and second foci may cause light to be subtended into one or more of collimated light focused light, diffused light, and shifted light. The carrier may include an obstruction extending toward the PCBA.
