摘要： A plasma lamp for an electrodeless plasma lamp having a waveguide body. The non-radiative thermal losses from the bulb are controlled to prevent the bulb from melting while providing a high level of radiation from the bulb. The thermal conductivity of the waveguide, configuration of the heat sink and size and placement of the bulb may be selected to provide a brightness of more than 80 lumens per watt and a total brightness of more than 12,000 lumens at a power level of 150 watts.

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 for an electrodeless plasma lamp having a dielectric waveguide body and a bulb positioned, at least in part, in the waveguide body and having at least one end protruding from the waveguide body. A probe is used to couple power into the waveguide body. The power resonates in the waveguide body and ignites a plasma in the bulb. By having one or both ends of the bulb extend beyond the surface of the waveguide body, the ends of the bulb are exposed to reduced electric field intensity, resulting in longer bulb lifetime due to reduced plasma impingement on the interior surfaces of the bulb.

摘要： In an example embodiment, an electrodeless plasma lamp is provided which comprises a dielectric body having an effective dielectric constant greater than two. The dielectric body may have a surface with a first region coated with an electrically conductive material and a second region that is not coated with the electrically conductive material. A bulb is located proximate to the second region of the dielectric body and having an outer surface area and the second region may have an uncoated surface area that is less than about sixty percent (60%) of the outer surface area of the bulb. A power source is coupled to the dielectric body to provide radio frequency power to the dielectric body at a frequency that resonates at a fundamental mode in the dielectric body. The bulb contains a fill that forms a plasma when the radio frequency power is provided from the dielectric body through the second region.

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.
