Abstract: A tubular discharge vessel for high pressure sodium vapor lamps has a wall 1 made of light-transmitting material. The tube 1 is hermetically sealed at each end by a respective ceramic stopper 2 through which is passed a respective current lead-in wire 11. An electrode 8 is joined via a shank 10 to the current lead-in wire 11. The interior of the tube is filled with noble gas(es) and metal additive(s), e.g. sodium, mercury and/or cadmium. A cavity 9, preferably of rotationally symmetrical shape is formed in at least one of the stoppers 2. In operation of the discharge tube the cavity 9 is the cold spot. i.e. the internal wall of the lowest temperature. The volume of the cavity 9 is at least equal to the volume of the metal additives in their liquid phase. In this way, in operation of the tube, the metal additives always condense in the cavity, the vitreous enamel bonds between the tube wall and the stoppers are free from chemically aggressive effects and whereby the self-stabilizing thermal processes taking place in the discharge vessel are promoted.

Abstract: The present invention relates to a method and apparatus for starting and maintaining a long electrical arc in an arc chamber containing a few atmospheres of pressure of an ionizable gas. An electrical potential difference is maintained between two fixed primary electrodes while a short arc is created between the first primary electrode and a pilot electrode, creating ionized gas. The ionized gas is caused to flow towards the second primary electrode thus creating a region of ionized gas between the two primary electrodes, and hence causing a long arc to be struck. This method does not require relative electrode movement as was the case previously.

Abstract: High pressure discharge lamps containing a fill of mercury and metal halides, having a power input of 250 watts or below and useable for general illuminating purposes achieve higher efficacy by developing high end temperatures without excessively obstructing the transmission of light and without creating excessive thermal losses through radiation and conduction. To reduce the obstruction of light, heat-conserving coatings on the lamp ends are preferably omitted and small neck seals are used which serve also to reduce thermal losses. The lamps are constructed with an aspect ratio of arc chamber length to diameter from 0.9 to 2.5 and with an electrode insertion factor from 0.1 to 0.6 and operate with a wall loading from 10 to 35 watts/cm.sup.2 and with an arc loading from 60 to 150 watts/cm.

An apparatus for performing the above method comprises two electrodes spaced apart to form a discharge region, a discharge chamber containing the discharge region, means arranged to apply a high voltage across the electrodes, and means arranged to supply water to the discharge region such that at least a part of the electrical discharge is submerged in the water, at least a portion of the discharge chamber being transparent to U.V. radiation. Also, a method of treating a material comprising producing U.V. radiation as described above in a discharge chamber at least a portion of which is U.V. transparent, passing the material through a treatment chamber adjacent the transparent portion of the discharge chamber; and an apparatus for performing the method of treating a material. In some described embodiments the position of an electrode is adjusted in dependence upon the electrical characteristics of the discharge such as to maintain predetermined conditions. In one embodiment an electrode is mounted in the bottom of the discharge chamber which forms the other electrode; water covers the electrode and has a controlled circulatory motion such as to control the height of water over the electrode and thus the submerged discharge path. In another embodiment one of the electrodes is formed by a layer of mercury; an initiating discharge between a third electrode and the mercury or the other electrode to establish a degree of ionisation of the mercury in the vicinity of the discharge region. The main discharge excites the mercury vapour resulting in radiation at 254 nm.
