<P>PROBLEM TO BE SOLVED: To provide a light source for a projector, capable of substantially increasing a quantity of light flux effectively taken out from a lamp forming a light source, and excellent in workability with high precision. <P>SOLUTION: This light source for a projector is provided with an arc tube 6 and a reflector 7 equipped with a concave reflecting surface to reflect light emitted from the arc tube and to emit it in its optical axis direction while holding the arc tube, and the reflector is provided with a first reflector 7a disposed in the vicinity of a holding part to hold the arc tube and a second reflector 7b disposed at a part other than the holding part and formed by containing a material different from the first member. In addition, the first reflector 7a is formed by a material containing heat-resisting glass, and the second reflector 7b is formed by a heat-resisting organic material having a lower thermal deformation temperature than the heat-resisting glass. <P>COPYRIGHT: (C)2003,JPO |
