摘要： In one example embodiment, an electrodeless plasma lamp comprises a source of radio frequency (RF) power, a bulb containing a fill that forms a plasma when the RF power is coupled to the fill, and a dipole antenna proximate the bulb. The dipole antenna may comprise a first dipole arm and a second dipole arm spaced apart from the first dipole arm. The source of RF power may be configured to couple the RF power to the dipole antenna such that an electric field is formed between the first dipole arm and the second dipole arm. The dipole antenna may be configured such that a portion of the electric field extends into the bulb and the RF power is coupled from the dipole antenna to the plasma. The invention extends to methods and systems for generating light in electrodeless plasma lamps.

摘要： An electrodeless plasma lamp and a method of generating light are provided. The plasma lamp may comprise a power source to provide radio frequency (RF) power, and a bulb containing a fill that forms a plasma when the RF power is coupled to the fill. The plasma lamp further comprises a resonant structure having a quarter wave resonant mode. The resonant structure includes a lamp body comprising a dielectric material having a relative permittivity greater than 2, an inner conductor, and an outer conductor. The power source is configured to provide the RF power to the lamp body at about a resonant frequency for the resonant structure.

摘要： An electrodeless plasma lamp is provided. The lamp includes a conductive enclosure including a dielectric material (e.g., air) and a bulb containing a fill to form a light emitting plasma. A radio frequency (RF) power source is coupled into the enclosure. At least one conductive applicator applies power from the enclosure to the bulb and at least one lumped inductive element is coupled between the RF feed and applicator. The lumped inductive element may be a helically wound coil. In an example embodiment, the lamp includes first and second lumped inductive elements. The first and second lumped inductive elements may extend from opposed end walls of the enclosure. The first lumped inductive element may be connected to a first conductive applicator located proximate a first end of the bulb and the second lumped inductive element may be connected to a second conductive applicator located proximate a second end of the bulb.

摘要： An electrodeless plasma lamp is described comprising a lamp body including a solid dielectric material. The lamp includes a bulb received at least partially within an opening in the solid dielectric material and a radio frequency (RF) feed configured to provide power to the solid dielectric material. A conductive material is provided adjacent to the bulb to concentrate the power proximate the bulb. The conductive material may be located below an upper surface of the solid dielectric material. The conductive material may modify at least a portion of an electric field proximate the bulb so that the portion of the electric field is oriented substantially parallel to an upper surface of the lamp body.

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： In various exemplary embodiments, an electrodeless plasma lamp includes a bulb configured to be coupled to a source of radio frequency (RF) power. The bulb contains a fill that forms a plasma when the RF power is coupled to the fill. An electrically-conductive convex shield is positioned proximate to the bulb with a convex surface of the shield being distal to the bulb. A resonant structure having a quarter wave resonant mode includes a lamp body having a dielectric material having a relative permittivity greater than 2 with an inner conductor and an outer conductor. The source of RF power is configured to provide RF power to the lamp body at about a resonant frequency for the resonant structure.

摘要： A micro-display projection system, including an intensity-modulated plasma lamp, rotating color wheel, micro-display imager, and system control electronics controlling the lamp, wheel and imager. Fast intensity modulation enables: controlling brightness and color tonal balance at the imager; optimizing dynamic range based on screen brightness; and compensating for 'green-snow' even when using a standard color wheel. Lamp light intensity is modulated according to the wheel rotation rate and phase, at a rate faster than the wheel rotation rate. Slow intensity modulation enables: optimizing lamp starting; lamp dimming; and compensating for aging components.
