摘要： An electrodeless plasma lamp having a lamp body and a power source configured to provide radio-frequency (RF) power via a feed to the lamp body is provided. The lamp includes a first conductive element and a second conductive element. The first conductive element has a first side with a first protrusion. The second conductive element has a second side with a second protrusion. The first side and second side face each other and spaced apart by a first distance and configured to couple the RF power via an electric field to a fill to form at least one plasma arc. The first protrusion and the second protrusion extend towards each other and are spaced apart by a second distance that is less than the first distance. The first and second protrusions may provide localized enhancement of the electric field at the first side and the second side.

摘要： 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.

摘要： A plasma lamp including a waveguide body comprising at least one dielectric material. The body is coupled to a microwave power source which causes the body to resonate in at least one resonant mode. A lamp chamber integrated with the body contains a bulb with a fill forming a light-emitting plasma when the chamber receives power from the resonating body. A bulb either is self-enclosed or an envelope sealed by a window or lens covering the chamber aperture. Embodiments disclosed include lamps having a drive probe and a feedback probe, and lamps having a drive probe, feedback probe and start probe, which minimize power reflected from the body back to the source.

摘要： 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.

摘要： 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.

摘要： A dielectric waveguide integrated plasma lamp is disclosed for powering a small and bright bulb with a diameter of a few millimeters. The lamp is contained within a high dielectric constant material which guides the microwaves to the bulb, provides heat isolation to the drive circuit, contains the microwaves, provides structural stability and ease of manufacturing and allows efficient energy coupling to the bulb when used as a dielectric resonant oscillator.
