Abstract
An improved termination fixture for an electrodeless light source matches the complex impedance of an electrodeless lamp during excitation to the output impedance of a high frequency power source coupled to the fixture. The inner conductor of the fixture has a first and a second section. The dimensions of the first section are such as to produce an input impedance whose reactive impedance part is much smaller than the reactive impedance part of the lamp impedance. The dimensions of the second section are such as to match the input impedance to the source output impedance.
