    摘要: Operation to produce an intermediate product for a crucible for a LUWPL is as follows: a) a body 2 is preheated and placed on a support, with its bore concentric with a tube 4 supported in a chuck and connected to a inflation means; b) the tube is heated with the chuck being rotated for evenness of heating; c) when the temperature of the tube is detected to be the softening point of the quartz of the tube, its rotation is stopped and it is advanced into a bore 3 in the body 2; d) advance is stopped when the distal, sealed end is detected to have reached a determined protrusion 18; e) simultaneously with the advance being stopped, inflation gas is admitted into the tube, to inflate it albeit it marginally, and bring its outer surface 5 into intimate contact with the surface 6 of the bore 4.

    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.

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.

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.

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.

    摘要: A lucent crucible of a Lucent Waveguide Microwave Plasma Light Source (LWMPLS) comprising a Light Emitting Resonator (LER) in form of a crucible (1) of fused quartz which has a central void (2) having microwave excitable material (3) within it. In one example, the void is 4 mm in diameter and has a length (L) of 21 mm. The LWMPLS is operated at a power (P) of 280 W and thus with a plasma loading P/L of 133 w/cm and a wall loading of 106 w/cm2. The lamp is thus operated with a high efficiency—in terms of lumens per watt—while having a reasonable lifetime.
