| titleOfInvention | Self-tuning electrodeless lamp |
| abstract | Summary A self-tuning system has an oscillator (30) and an oscillator-driven load, which uses the oscillator-driven load as a frequency determinant of a resonant system. In one example, the oscillator-driven load is a lamp head circuit for an electrodeless lamp. The lamp head circuit of the electrodeless lamp has an excitation coil (40) proximate an encapsulation or bulb (42) containing a fill, which fill forms a plasma discharge when ignited. I do. A variety of oscillator configurations can be used with the load, including a modified Hartley (30A), modified Colpitts (30B), and modified armstrong configuration (30C). Various embodiments of the clamp circuit (100) can also be used to limit the feedback signal applied by the feedback system to the area allowed by the amplifier. Of particular interest to the present invention are self-tuning systems that operate at high frequencies and high power. Illustrative embodiments of high frequency and high power electrodeless lamps and various inventive aspects of a high frequency high power self-tuning system, for example, to provide sufficient gain and improve ignition / self-start (eg, reduced start-up time) Technology is provided. Techniques and configurations for ensuring sufficient gain for the self-tuning system of the present invention include the choice of oscillator configuration, multi-stage amplification (if required), and feedback system configuration. Self-ignition of the load can be achieved, for example, by using a special starting oscillator, by using a low-pressure noble gas charge for the lamp bulb, and by increasing the current in the excitation coil (eg, by selectively connecting the tap (60) to the excitation coil. Positioning). |
