Abstract
A light source apparatus in which an optical arrangement of a light source and a concave mirror is properly adjusted without requiring a large-scale device and a method for manufacturing the same, an adjusting device for adjusting the optical arrangement in the light source apparatus, and a lighting system and a projection display system using the light source apparatus. A lamp housing in which the optical arrangement is adjusted is realized by mounting a tungsten lamp anchoring plate ( ), to which a tungsten lamp ( ) is fixed, to an ellipsoidal mirror anchoring plate ( ) before mounting an arc lamp; moving and fixing a base substrate ( ) on a bottom plate ( ) so that the diameter of a light spot of light reflected by an ellipsoidal mirror ( ) and condensed on an ellipsoidal mirror condensed-state confirming surface ( ) at a minimum, the ellipsoidal mirror condensed-state confirming surface ( ) being placed at the position where the second focal point of the ellipsoidal mirror ( ) should be placed; and removing the tungsten lamp ( ) and mounting the arc lamp. Furthermore, a lighting system and a projection display system are constructed using this lamp housing.
