Abstract: An oscillator includes a solid state active device having an input and an output, a feedback circuit connected from the output of the active device to the input of the active device, the feedback circuit providing suitable positive feedback to initiate and sustain an oscillating condition at a fundamental frequency, and a waveform modifying circuit connected to the output of the active device, wherein the waveform modifying circuit is adapted to modify the waveform on the output in a manner which increases an efficiency of the oscillator. For example, the waveform modifying circuit comprises transmission lines and optionally components which provide a high impedance for odd harmonics of the fundamental frequency. The waveform modifying circuit may further include transmission lines and optionally components which provide a low impedance for even harmonics of the fundamental frequency. The waveform modifying circuit utilize class F amplifier principles to cause the waveform on the output to be relatively more square in shape.

Abstract: A high frequency inductively coupled electrodeless lamp includes an excitation coil with an effective electrical length which is less than one half wavelength of a driving frequency applied thereto, preferably much less. The driving frequency may be greater than 100 MHz and is preferably as high as 915 MHz. Preferably, the excitation coil is configured as a non-helical, semi-cylindrical conductive surface having less than one turn, in the general shape of a wedding ring. At high frequencies, the current in the coil forms two loops which are spaced apart and parallel to each other. Configured appropriately, the coil approximates a Helmholtz configuration. The lamp preferably utilizes an bulb encased in a reflective ceramic cup with a pre-formed aperture defined therethrough. The ceramic cup may include structural features to aid in alignment and I or a flanged face to aid in thermal management. The lamp head is preferably an integrated lamp head comprising a metal matrix composite surrounding an insulating ceramic with the excitation integrally formed on the ceramic. A novel solid-state oscillator preferably provides RF power to the lamp. The oscillator is a single active element device capable of providing over 70 watts of power at over 70% efficiency. Various control circuits may be employed to adjust the driving frequency of the oscillator.
