专利说明:
The invention relates to electric bulbs equipped with a ceramic discharge tube and a current lead consisting of two or more single filaments, preferably wire, passing through a ceramic sealing element. Gas discharge lamps are known in which the closure element comprises a thin-walled niobium tube. In this case, the undesirable effects of the expansion caused by the high temperatures that occur during burning are compensated for by the elasticity of the thin-walled tube 1. There are also known gas discharge lamps in which a part of the current lead connected to the electrode through the ceramic closure element and enclosed in this element continues in a spiral, the envelope of the lamp axis as a result of which the effect of an electric shock can be delayed and, accordingly, compensated for Г 2}. A disadvantage of the known light sources is that the structural dimensions of the spiral curved one in the lamp can be increased only within certain limits, since they are limited by the size of the ceramic discharge tube of the lamp and the distance between the electrodes. As a result, the impact of thermal shock cannot be completely eliminated, and imparting a spiral shape to the electrode and the need to use a special contact pin leads to a complication of the design. Closest to the proposed technical entity is an elec- tric gas discharge lamp containing a tube of ceramic or crystalline material from an electrode; MI installed inside it on the pro. opposite ends with current leads, each of which contains a niobium wire connecting the electrode with a corresponding external current lead and hermetically sunk into the element covering the end of the tube and a full ceramic material. One of the drawbacks of such a lamp is the difficulty of fabricating j, since it is necessary to butt the electrode with the current lead. In addition, an increase in the power of gas discharge lamps leads to the need to increase the currents applied to the electrodes. Accordingly, the cross-section of the current lead should be proportionally increased. However, an increase in the cross-section of the current lead complicates its sealing, since with an increase in the current through the current lead, rattling and damage occur in the ceramic covering element. The purpose of the invention is to improve the manufacturability and improve its electrical and mechanical parameters. To achieve this goal, an electric gas discharge lamp containing a tube of ceramic or crystalline material with electrodes installed inside it at opposite ends using current leads, each of which contains a niobium wire, connects the electrode with a corresponding external current lead and is hermetically sealed into the element closing the end of the tube and made of a ceramic material, the caddy of the current-paths is provided with at least one additional niobium wire, sealed VPA constant in said element, the wire connected between the cor fight on both sides of the closure member. Wires can be connected U-shaped or shifted with each other. In FIG. 1 is schematically represented by the {gas discharge lamp, a general view in FIG. 2, 3, and 4 are the same, longitudinal sections and vtsd from above-- (the current lead is made up of single single wires connected U-shaped), in FIG. 5 and 6 are the same, two longitudinal sections (the current lead consists of four wires, there is a firing electrode) J in FIG. 7 and 8 - the same longitudinal section and top view (wires are twisted between themselves in the discharge zone and outside eej. The lamp is equipped with a ceramic discharge tube 1 enclosed in a glass cylinder 2 in which a vacuum is created or an inert gas is present, as well as base 3. The current lead 4 consists of two or several single filaments 5 (in the preferred embodiment, made of niobium wire), sunk into the ceramic closure element 6, connected to the electrode / 7, located in the discharge zone and twisted at the outer end. at one of the end of t The slabs 1 through the support 8 and the external current lead 9 are connected to the base 3, and the current lead at the second end of the tube 1 is connected to the lamp base through the second support and the second external current lead 10. The ceramic discharge tube 1 is installed in the electric discharge lamp 8 and the support ring 12. The lamp has a current lead 4, consisting of four single filaments 5, for example niobium wires, passing through the ceramic element 6, which is covered with a ceramic discharge tube 1. Each two filaments of four connected to the electrode 7 and located at discharge zone, electrically and thermally conductively short-circuited and bent into a U-shaped element. In this case, outside the discharge zone, all four single filaments are interlaced and form a rigid structure that meets the strength requirements. The device shown in FIG. and 3, are made as follows: Four grooves are made in the closing element. Two single strands are pre-bent U-shaped, hermetically sealed into these grooves using ceramic or vitreous solder. Then U-shaped niobium wires are welded to electrode 7. Four free ends: single wires are twisted on the other side of the ceramic covering element 6, Thus, the current | Input 4, consisting of single threads 5, is electrically and heat-conductingly short-circuited sides of the closing element b. After such preparation, the ceramic covering element is hermetically sealed to the end of the ceramic section. tube 1. At a high-pressure sodium gas discharge lamp, have a power of 400 W and a supply voltage; NIL 200 V performed as described above, the inner diameter of the ceramic tube 1 reaches 8 mm, the diameter of the niobium wire is: 0 , 5 mm, and the diameter of the tungsten electrode is 1.2 mm. In the embodiment depicted in Figures 5 and 6, four single filaments 5 pass through the ceramic covering element 6, which covers the discharge of tubes 1 574 cu 1. Two pairs of these filaments are short-circuited in the discharge zone and are U-shaped. One U-shaped element is connected to electrode 7, and the other is connected to auxiliary electrode 13. At the same time, both pairs of new wires are twisted each separately outside the discharge zone and form current leads 14 and 4, respectively. In the embodiment shown in Fig. 7, the current lead 4 consists of three single niobium wires 5 passing through. through the ceramic closure element with which the ceramic discharge tube 1 is closed. The ends of the single filaments 5 are connected to the electrode 7, and the other ends outside the discharge zone are interlaced. The invention is not limited to the described variants. It is possible to manufacture current leads from two or more single filaments, preferably niobium wires, passing through the ceramic closed cell, since the number and size of single filaments depend on the power of the electric lamp with a ceramic discharge tube. Experiments have shown that when using niobium wires, it is advisable to increase their cross section to 0.28 sq. Mm, since in the case of soldering to the closing element of a wire with a solid cross section exceeding this value, thermal shocks occur, resulting in cracks. current lead can be made - depending on lamp power - from two, three, four, etc. single strands arranged arbitrarily. The specific arrangement of the single filaments forming the current lead in the ceramic covering element is not essential. The essence of the invention is that the filaments should be soldered into the closing element each separately, regardless of the specific design of the current lead. To concentrate and support the electrodes and to facilitate welding, it is advisable to choose an even number of single strands, preferably two or four. If one or more single strands are to be used as additional electrodes, it is convenient to use an odd number of strands. In the latter case, a current lead for the auxiliary electrode, a current lead for the main electrode is formed from two or more single filaments. The cross section and the shape of the single filaments forming the current lead are not significant. Obviously, single filaments located in the discharge zone and connected to the electrode provide an electrical and thermal short circuit not only in the case of giving them a U-shape, but also in any other case, for example, when individual straight single filaments are welded in transverse direction to preferably flat plate I 12 P ,ten S I 2 Rig. g 7J fPue.S fPu3.7 Fig.b
