Title:
LIGHT SOURCE DEVICE
Document Type and Number:
Japanese Patent JP2013200944
Kind Code:
A
Abstract:

To provide a light source device capable of detecting leakage of a coolant from a cooling system for cooling the light source device and preventing damage to a light source and a power source due to adhesion of the coolant.

A light source device includes: a conductive cooling section 1 capable of internally circulating coolant; irradiation sections 21a, 21b connected at the outside of the cooling section 1 so as to be cooled with the coolant; a detection electrode 41 arranged at a position electrically insulated against the cooling section 1 and at a position where the coolant can be crosslinked between the cooling section 1 and the detection electrode 41 when the coolant leaks from the cooling section 1; and a detection section 51 for detecting electric characteristics between the detection electrode 41 and the cooling section 1, and detecting leakage by means of the changes in the electric characteristics.
