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 /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 1/16 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.

A crucible for a LUWPL is formed from a wave guide body having a central bore through it. Received within the central bore is a drawn quartz tube having its ends sealed, one having been worked flat to be coplanar with one face of the body. The other end has a vestigial tip. This is secured to the body at the orifice of the bore in the other face of the body. The securement is by means of ceramic adhesive compound.


A LUWPL luminaire has a housing with a lower transparent closure and a heat dissipating top of cast aluminum. This has a suspension eye. The housing has an upper flange via which it is bolted with the interposition of a seal to a underside rim of the top. Within the rim, the underside is substantially flat, with a magnetron attachment boss and other attachment points. A magnetron is supported by being clamped by a saddle to the attachment boss at the magnetrons anode. The magnetron is fast with a transition box and a crucible support block. A bracket fixed to certain of the attachment points extends down from the top is screwed to the transition box. Thus the LUWPL parts are securely supported below the top.

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.

A plasma crucible (92) has a through bore (93) and two tubes (981,982) butt sealed on to the end faces (901,902) of the crucible. One (981) of the tubes is closed prior to the filling of the crucible. The tube is tipped off and worked in a glass lathe to form it to have a flat end (983). After evacuation, dosing and gas fill, the end (983) is heated to drive off impurities in the dose, with its active constituent condensing within the bore (93). Then, the other tube (902) is tipped off in the similar manner.

A lamp has a solid plasma crucible 101 of polished quartz, with a flat front face 102 and a parabolic rear face 103. The front face is coated with indium tin oxide 104 to render it electrically conductive, yet transparent. In electrical contact with the ITO layer, is a platinum layer 105 on the parabolic rear. These two layers together form a Faraday cage around the quartz plasma crucible. At the focus of the parabola and aligned with its central axis is a void 106, filled with microwave excitable material 107, typically indium halide in xenon. The void is a bore in the quartz, that is sealed by means of a plug 108, the plug having been fused in place without other material by laser sealing. Alongside the void is a receptacle 109 in the quartz for a metal rod antenna 110. This is connected directly to the output 111 of a matching circuit such as the circuit 3. An adaptor plate 112 of the circuit has a contour 113 complementary to that of the rear face of the quartz plasma crucible. A fastening ring 114 pulls the quartz into contact with the end plate, for grounding of the Faraday cage. On propagation of microwaves from the matching circuit, resonance is set up in the quartz plasma crucible and a plasma is established in the void. Light is emitted from the halide in the void. This either leaves the plasma crucible directly through the front face 102 or is reflected by the platinum layer 105 at the parabolic back face 103 forwards to exit the front face.
