Abstract: The present disclosure relates to apparatuses and methods to control an electrodeless plasma light source. In various embodiments, an apparatus is provided that includes an electrodeless plasma lamp with a lamp driver circuit. The lamp driver circuit may include a voltage-controlled oscillator to provide radio frequency power to the electrodeless plasma lamp. A radio frequency power detector is coupled to an output of the voltage-controlled oscillator to detect a level of reflected power from the electrodeless plasma lamp. A microprocessor is configured to receive signals from the radio frequency power detector and control a frequency of the voltage-controlled oscillator to minimize the reflected power from the electrodeless plasma lamp.

Abstract: A lamp and methods of forming are shown. In one example, a dielectric layer is formed over a gap between conductors in a plasma lamp. Electric arcing is reduced or eliminated, thus allowing tighter gaps and/or higher voltages. In one example a glass frit method is used to apply the dielectric layer. A lamp is shown with a barrier layer that prevents tarnish such as tarnish from sulfur exposure. The barrier layer reduces or prevents degradation of the lamp due to conversion of a conductor material to non-conductive tarnish material.

Abstract: An electrodeless plasma lamp and a method of generating light are described. The lamp may comprise a lamp body including a dielectric material. The bulb is positioned proximate the lamp body and contains a fill that forms a plasma when radio frequency (RF) power is coupled to the fill. The conductive element is located within the lamp body and configured to enhance coupling of the RF power to the fill. The lamp may include a feed coupled to the RF power source and configured to radiate power into the lamp body. The at least one conductive element is configured to enhance the coupling of radiated power from the feed to the fill. In an example, two spaced apart conductive elements may be located within the lamp body. The bulb may be an elongated bulb having opposed ends, each opposed end of the bulb being proximate a corresponding conductive element.

Abstract: A plasma lamp is described with resonant frequency tuning capability and associated methods for tuning. One tuning method allows plasma lamp manufacturer to set the frequency of lamps to several discrete predetermined values. For example, most lamps that are near the center of a frequency distribution can be tuned to a nominal value such as 918.7 MHz. Other frequencies can also be tuned to increase manufacturing yield and improve lamp performance.

Abstract: In one example embodiment, a drive probe is coupled to the lamp body to provide the primary power for ignition and steady state operation of the lamp. Feedback may be used to adjust frequency in response to changing conditions of the lamp during startup. A phase shifter may be used to adjust the phase of the power between ignition and steady state operation. A sensor may detect a lamp operating condition that automatically triggers a shift in phase after the fill in the bulb is vaporized. In another example embodiment, a method for sequentially optimizing the drive power and phase shift applied to the lamp is disclosed that may reliably regulate the lamp current consumption to desired startup and operational levels despite variations in lamp environmental conditions.
