摘要： A plasma lamp for an electrodeless plasma lamp having a waveguide body with an effective dielectric constant of at least 2. A drive probe is coupled to the waveguide body to provide the primary power for ignition and steady state operation of the lamp. A phase shifter is used to adjust the phase of the power provided to the drive probe between ignition and steady state operation. The phase shifter may also be used to adjust brightness during steady state operation.

The power source is coupled to the lamp body by a feed to provide power to the lamp body. A bulb containing a fill having a first portion and a second portion is provided. The bulb is positioned so that the first portion of the fill is located within the lamp body and the second portion of the fill is located outside of the lamp body. In use, the fill receives at least a portion of the power from the lamp body to form a light-emitting plasma. The volume of the bulb is less than the volume of the lamp body.

摘要： A dielectric waveguide integrated plasma lamp (DWIPL) with a body comprising at least one dielectric material having a dielectric constant greater than approximately 2, and having a shape and dimensions such that the body resonates in at least one resonant mode when microwave energy of an appropriate frequency is coupled into the body. A dielectric bulb within a lamp chamber in the body contains a fill which when receiving energy from the resonating body forms a light-emitting plasma. The bulb is transparent to visible light and infrared radiation emitted by the plasma. Radiative energy lost from the plasma is recycled by reflecting the radiation from thin-film, multi-layer coatings on bulb exterior surfaces and/or lamp chamber surfaces back into the bulb. The lamp further includes two- or three-microwave probe configurations minimizing power reflected from the body back to the microwave source when the source operates: (a) at a frequency such that the body resonates in a single mode; or (b) at one frequency such that the body resonates in a relatively higher mode before a plasma is formed, and at another frequency such that the body resonates in a relatively lower order mode after the plasma reaches steady state.

摘要： A plasma lamp for an electrodeless plasma lamp having a shaped dielectric waveguide body. The shaped body may have a relatively thin region containing a bulb, and a second region thicker than the first region. Microwave probes may be positioned in the second region to provide power to the waveguide body. The body may be shaped to intensify the electric field in the first region adjacent to the bulb to allow operation at a lower frequency than a solid cylindrical or rectangular waveguide body having the same volume and dielectric constant.

摘要： A plasma lamp with a positive-loop feedback topology, having a resonating waveguide body and at least one amplifier critically coupled to the body which is stable under all operating conditions both before a plasma is formed and after the plasma reaches steady state. An iterative method for configuring the lamp circuit includes determining the load trajectory of each amplifier under all operating conditions, and overlaying it on a polar-plot showing regions of stability, conditional stability, and instability. If the load trajectory passes through an unstable region, circuit alterations are made to avoid that region.
