Abstract: A High Frequency light source (11) has a central body (12) of fused quartz, with a central void (14), filled with a fill (16) in the void of material excitable by High Frequency energy to form a light emitting plasma. An inner sleeve (17) of perforate metal shim extends along the length of the central body to within 2.5 mm of its void end to provide a launching gap (18). The sleeve has a transverse end portion (19) extending across the other, inner end of the central body. An outer cylinder of fused quartz (20) with an internal bore (21) such as to be a sliding fit with the inner sleeve, itself a sliding fit on the central body. An outer sleeve (22) of perforate metal, enclosing the outer cylinder and having an end portion (23) extending across the flush, void ends of the quartz body and cylinder (12,20). The outer sleeve has a skirt (25) extending past the flush other ends of the quartz elements over an aluminium carrier (26), where it is clamped, holding the quartz elements against the carrier. Thus the sleeve forms with, with its end (23) and the carrier (26), a Faraday cage around the quartz and the plasma void (14). An antenna (27) insulated from the carrier extends from it into a bore (28) in the quartz cylinder (20) for introducing HF radiation into the coaxial wave guide formed by the inner and outer sleeves (17,22). Their perforation is such as to make them opaque and enclosing to the HF radiation yet light transmissive, whereby light from the plasma can pass through them. The portion of the antenna in the carrier provides a connection to an non-shown source of HF energy. The inner sleeve (17), at its end portion (19), is earthed to the carrier, in the same way as the outer sleeve and its end portion (23). Thus the gap (18) between the end of the inner sleeve and the end portion of the Faraday cage forms a launching gap for the HF energy to radiate to the plasma void and establish and maintain the plasma there. Light from the plasma passes through the quartz and through the perforations in the sleeves and the end portion (19), thus out of the light source.

Abstract: A plasma crucible has a through bore and two tubes butt scaled on to the end faces of the crucible. One 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. After evacuation, dosing and gas fill, the other tube is tipped off in the similar manner.

Abstract: 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.

Abstract: A Lucent Waveguide Electromagnetic wave Plasma Light Source has a fabrication of fused quartz sheet and drawn tube. An inner closed void enclosure is formed of 8 mm outside diameter, 4 mm inside diameter drawn tube. Electromagnetic wave excitable plasma material is sealed inside the enclosure. The end plate is circular and has the enclosure sealed in a central bore in it, the bore not being numbered as such. A similar plate is positioned to leave a small gap between the inner end of the enclosure and itself. The two tubes are concentric with the two plates extending at right angles to their central axis. The outer tube extends back from the back surface of the inner plate as a skirt.

Abstract: An electrodeless bulb has a hollow quartz tube, with a solid stem extending from one end and a short hollow tip extending from the other end. The hollow interior of the tube extends into the tip with the same diameter as in the tube, but the wall thickness of the tip is reduced from that of the tube. The bulb is charged with an amount of indium bromide and traces of other metal halides to adjust light spectrum and a filling of xenon gas.

Abstract: 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).
