Beschreibung
Zusammenfassung:	There is provided yellow and red illumination systems, including a semiconductor light emitter, and a luminescent material. The systems have an emission falling within the respective ITE red and yellow color bins having specified color coordinates on the CIE chromaticity diagram. The luminescent material may include one or more phosphors. The illumination systems may be used as the red and yellow lights of a traffic light or an automotive display.
