ABSTRACT:
A method and apparatus for exciting an electrodeless light bulb containing material including an inert gas and one or more chemical elements which generate a light emitting torus of plasma when excited by an RF signal and which includes two separate excitation coils oriented about the bulb so that the planes of each of the coils are mutually oriented 90.degree. with respect to each other, and wherein each of the coils are driven by respective RF excitation voltages having mutually different frequencies, for example, a difference of 4%, so as to excite the material enclosed within the bulb and cause a stirring action of the fill and effect a pulsating emission of light and rotation of the torus similar to that produced by physical rotation of the bulb itself.
