Abstract:
1. A light source apparatus comprising: a lighting power source configured to feed electricity to an excimer lamp at which an IC tag is disposed; an IC tag reading unit configured to read information from the IC tag disposed at the excimer lamp; an optical sensor configured to measure illuminance of a light emitted from the excimer lamp that is lighting; and a controller configured to control the lighting power source according to an output from the optical sensor to control the illuminance of the light of the excimer lamp, the lighting power source being configured to be shared among excimer lamps that have an equal lighting condition and different emission wavelengths, the controller being configured to store at least usable lamp information identifying an excimer lamp that is usable for the light source apparatus, and a sensitivity correction value for correcting a sensitivity of the optical sensor that corresponds to an emission wavelength of each usable excimer lamp, the IC tag being configured to store at least lamp identifying information identifying an excimer lamp at which the IC tag is disposed, the controller being configured, when the light source apparatus is driven to cause the excimer lamp to light, to determine whether the excimer lamp mounted on the light source apparatus is usable and capable of emitting a light at a desired emission wavelength based on the lamp identifying information read from the IC tag by the IC tag reading unit and the usable lamp information stored in the controller, and the controller being configured, if the controller determines that the excimer lamp is usable and capable of emitting the light at the desired emission wavelength, to allow the excimer lamp to normally light and correct the sensitivity of the optical sensor with the sensitivity correction value.
