摘要： An LER LUWPL source luminaire having a magnetron heat conductingly mounted below a finned heat dissipater with a suspension eye. The magnetron is attached to a microwave transition and a lucent crucible. An imperforate cover extends down from the heat dissipater and is closed by a transparent screen, held by a molding. A generally square shaped molding supports a polished-sheet-metal reflector (having four triangular faces, pyramidally arranged, with a square base embodied by a rim supported on the top of the screen above the molding) extending back to the lucent crucible, with its reflective surfaces obliquely facing both the crucible and the screen for reflection of light from the crucible out of the luminaire via the screen. The faces converge to a virtual apex, on the central axis of the lucent crucible. This axis is coincident with the pyramid's normal axis from the apex to the center of the base.

摘要： A lamp has microwave resonant body (11) of transparent quartz. The body has a central bore (16), having a sealed plasma enclosing bulb (17) inserted in it. The bulb is of quartz also and has an external diameter which is a close fit in the bore. The bulb itself is of drawn quartz tube (18) and as such has a smooth internal bore (19). End caps (20) are fused to the tube and encapsulate a charge of a material excitable to form a light emitting plasma in the bulb when microwaves are fed into the body via an antenna (7) in a bore (21) in the body. The body is sized to establish resonance within the Faraday cage in the body (11), bulb (17) and fill containing void (22) within the bulb. There is negligible gap between the bulb and body, whereby they can be regarded as one for resonance purposes. The bulb is fixed in the body by welds (23).

摘要： The manufacture of an electrodeless bulb involves one end of a tube closed off, and a first neck is formed in the tube close to the closed end. A second neck is formed in the tube, close to the still open end; a metal halide pellet of known size is dropped into the tube and the tube is evacuated. With the vacuum being maintained heat is applied to the closed end, causing the metal halide pellet to sublime and with it the impurities. The impurities are drawn off, the vacuum being maintained and the metal halide condenses in the tube between the necks. Once the tube is cool, the evacuation is discontinued and the tube is refilled with noble gas and the quartz tube is sealed off at the second neck.

摘要： A lamp 1 comprises an oscillator and amplifier source 2 of microwave energy, typically operating at 2.45 or 5.8 GHz or other frequencies within an ISM band. The source passes the microwaves via a matching circuit 3 to an antenna 4 extending into a re -entrant 5 in a lucent waveguide 6. This is of quartz and has a central cavity 7 accommodating a bulb 8. The bulb is a sealed tube 9 of quartz and contains a fill of noble gas and a microwave excitable material, which radiates visible light when excited by microwaves. The bulb has a stem 10 received in a stem bore 11 extending from the central cavity. The waveguide is transparent and light from the bulb can leave it in any direction, subject to any reflective surfaces. Microwaves cannot leave the waveguide, which is limited at its surfaces by a Faraday cage. Typically this comprises an ITO coating 12 on a front face of the waveguide, a light reflective coating 10, typically of silver with silicon monoxide coating 13 on a rear face and a wire mesh 14, which contacts both the ITO and light reflective coatings and is grounded, the wire mesh extending around sides of the waveguide between the front and back surfaces. Light can pass through the wire mesh for collection and use.

摘要： A lamp with a quartz electrodeless bulb has a ceramic wave guide with a central void, in which the bulb is accommodated. The wave guide is rectangular. The central void is centered on a central longitudinal plane of the wave guide, normal to front and back faces of the wave guide and equally spaced from end faces. Parallel with the central void and also on the central plane are two further voids for respective antennae. The central void is open through the front face for egress of light, but the antenna voids are not open in this face. The latter is metalized to inhibit egress of microwave energy from the wave guide.

摘要： A light source is powered by a magnetron and has a quartz crucible having a plasma void with an excitable fill, from which light radiates in use. Two aluminium attachment blocks are attached together and the block is attached to a casing of the magnetron by screws - not shown. The quartz crucible is attached to the block by a Faraday cage, in the form of a perforate metal enclosure secured at its rim to the block. An output formation of the magnetron has a conductive, copper cap fitted in electrical contact with it. The cap is extended by a copper rod. The rod extends through the blocks into a bore in the crucible for coupling microwaves from the magnetron into the crucible. An airspace is provided around the cap in the block. From the cap, the rod extends with negligible air gap in an alumina ceramic tube through the airspace and a boss of the block located in an aperture in an end wall of the block.

摘要： A bandpass filter comprises an air filled aluminum chamber having a lid and a cuboid resonant cavity having a central iris. At opposite end nodes of the cavity, perfect electric conductors (PECs) are provided. Threaded tuning projections opposite the PECs and in the iris are provided, whereby the pass band and the transmission characteristics of the filter in the pass band can be tuned to match the input impedance of the band pass filter and the wave guide to the output impedance of a microwave drive circuit. It is mounted on one end of the filter chamber, with an electrodeless bulb in a central cavity directed axially away from the chamber and the radiator in a further cavity set to one side of the central cavity. When the filter is driven, the wave guide resonates driving the bulb.

摘要： A lamp comprises a light source in the form of a light emitting resonator 1, a magnetron 2 and a stub tuner 3. A reflector 4 is fitted at the junction of the light source and the stub tuner, for directing the light in a generally collimated beam 5. The light emitting resonator comprises an enclosure 11 formed of inner and outer envelopes 12,13 of quartz. These are circular cylindrical tubes 14,15, with respective end plates 16,17. A tungsten wire mesh 18, of a mesh size to exhibit a ground plane to microwaves within the resonator, is sandwiched between the tubes and the end plates respectively. Each envelope, comprised of its tube and end plates is hermetic. An earth connection 18′ extends from the mesh to the outside of the envelope.The length axially of the enclosure between the wire mesh sandwiched between the end plates is λ/2 for the operating microwave frequency. At one end of the enclosure, a molybdenum drive connection 19 extends to a tungsten disc 20. This is arranged transverse the axis A of the enclosure at 1/16λ from the mesh at its end of the enclosure. The enclosure is filled with excitable plasma material, such as a dose of metal halide in a rare earth gas.The disc acts as antenna and is driven by the magnetron 2, via the matching circuit 3.
