Abstract: A light source apparatus includes a cooling mechanism driving portion for driving a cooling mechanism in such a manner that an element temperature of a light source element which is detected by an element temperature detecting portion reaches a target temperature, and a control portion for calculating a dew point temperature of the cooling mechanism and controlling the cooling mechanism driving portion and a light source element driving portion by using the calculated dew point temperature and the element temperature.

Abstract: A light source apparatus includes an outer casing. A light source member and a light source module having a cooling body which cools the light source member are disposed in the outer casing. A wind tunnel which surrounds a heat pipe unit as the cooling body of the light source module is provided in the outer casing. The wind tunnel includes a wind passage which allows cooling wind to pass through the heat pipe unit. An intake-opening is formed in a surface of the outer casing, and cooling wind is taken into the outer casing from outside thereof through the intake-opening. One end of the wind passage of the wind tunnel is connected to the intake-opening.

Abstract: A laser light source apparatus includes a laser light source; a heat exchanger that includes a plurality of cooling fins and that cools the laser light source; a driving circuit that drives the laser light source; a housing including an intake port and an exhaust port; and an air-cooling fan that is attached to the housing and that discharges air taken in from the intake port to the exhaust port. The cooling fins are arranged at a position opposed to the intake port to be stacked up on each other at predetermined intervals and a pitch between the cooling fins is equal to or less than a minimum width of the intake port.
