ABSTRACT:
A light source apparatus excites an electrodeless lamp bulb with energy of microwaves generated from a magnetron. A microwave transmission line is improved so that microwaves can be transmitted efficiently and the light source apparatus can be miniaturized. A first cylindrical member is disposed coaxially with a direction in which microwaves generated from the magnetron are transmitted, and a second cylindrical member is disposed at the center of the first cylindrical member, thereby forming a coaxial transmission line. A coaxial oscillator is formed from the position at which the microwaves are generated to a position of 1/4 of the wavelength of the microwave. Thus, a special waveguide can be removed.
