摘要： A projection light source may include a housing and an arc tube supported by the housing. The arc tube may include an arc tube body having a bulbous chamber intermediate sealed end portions, a pair of electrodes, a fill gas contained within the chamber, a fill material contained within the chamber, and a generally ellipsoidal reflector supported by the housing. The arc tube and the reflector may be positioned so that a focus of the generally ellipsoidal reflector lies on an axis extending between the interior tips of the electrodes of the arc tube.
