fluorescent lamp, microwave methods, electrodeless lamp.

The excitation of a commercial fluorescent lamp is obtained with easy using a coaxial dipole antenna placed along its external surface. We present the results obtained making direct comparison between the luminous flux emitted by a commercial fluorescent lamp fed with 220 V ac power or, alternatively, with microwave power at 2.545 GHz. The luminous efficiency attainable with microwaves and details on the associated technology are reported. An account of the possible advantages of the novel method of excitation are also given in view of the construction of fluorescent lamps of industrial and civil interest.
