Claim Text:
1. A light source apparatus comprising: a light source element for emitting light; a light source element driving portion for driving said light source element; a cooling mechanism for cooling said light source element; an element temperature detecting portion for detecting an element temperature to be a temperature of said light source element; an ambient temperature detecting portion for detecting an ambient temperature of said light source apparatus; an ambient humidity detecting portion for detecting an ambient humidity of said light source apparatus; a cooling mechanism driving portion for driving said cooling mechanism in such a manner that said element temperature to be detected by said element temperature detecting portion reaches a target temperature; and a control portion for calculating a dew point temperature of said cooling mechanism using said ambient temperature and said ambient humidity, and controlling said cooling mechanism driving portion and said light source element driving portion by using said calculated dew point temperature and said element temperature.
