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 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： 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.

摘要： In an example embodiment, an electrodeless plasma lamp is provided which comprises a lamp body comprising a dielectric material having a relative permittivity greater than 2, and a bulb adjacent to the lamp body, the bulb containing a fill that forms a plasma when RF power is coupled to the fill from the lamp body. An RF feed is coupled to the lamp body and a radio frequency (RF) power source for coupling power into the lamp body through the RF feed is provided. A shortest distance between an end of the bulb and a point on the RF feed traverses at least one electrically conductive material of the lamp body.

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.

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 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： An electrodeless plasma lamp array structure uses multiple plasma lamps to produce large amounts of electromagnetic radiation (visible, IR, UV, or a combination of visible, IR, and UV). An M by N array configuration is powered by either a single RF power source or multiple RF power sources. The array incorporates controllers to adjust the power delivered from the RF power source to each lamp within the array. By adjusting the delivered RF power, the intensity of electromagnetic radiation that is emitted from each lamp is controlled independently allowing for the creation of an array of lamps that emit electromagnetic radiation of varying intensity levels at different places within the array. Using lamps with different color temperatures as part of the array allows the color temperature and the color rendering index of the illumination to achieve different lighting conditions.
