专利说明:
The invention relates to electrical engineering, in particular, to the construction of a radial lamp having a tubular flask of ceramic or sapphire, the front sides of which are hermetically sealed to form capillaries by melting the solder with locking elements containing electrodes attached to them. The creation of end locks used in alkali metal vapor lamps, tubular discharge flasks made of ceramics, especially sapphire, is, as is known, a fundamentally difficult task. The material of the bulb of the discharge lamp is pericapristine alumina or sapphire, and for the closure element it is ceramics with at least a partially metallized surface or metal, in particular niobium G 1. However, fusing the components of this discharge lamp is associated with some difficulties. . Stresses can occur even with the same coefficients of thermal expansion, if;:. These components have different masses. 1 or even at the same time are cooled or heated. Similarly, workers do not appear when the lamp is turned on or off. Closest to the present invention is a discharge lamp containing a ceramic or sapphire flask, closed at the ends with locking elements containing electrodes to form capillaries filled with solder. In the manufacture of the lamp, an annular piece of solder is used on which the stop element Solder is melted at, and shut off element Immersed in flask C2. However, in the case of uneven melting, the valve is introduced into the flask in the upturned position, which is undesirable. In addition, fixing the locking element at such a high temperature is almost impossible. The discharge lamps made in this way have low resistance to thermal shocks and do not meet the requirements of quality. The purpose of the invention is to simplify the manufacture of the lamp and improve its quality. This goal is achieved by the fact that in a discharge lamp containing a ceramic or sapphire flask 15, closed at the ends of the locking elements containing electr-ady with the formation of capillaries filled with solder, these locking elements are made of internal and axisymmetric parts, and the axisymmetric part is made annular, and the joined surfaces of both parts are located above the end of the flask wall. The inner part of the locking element; It can be made in the form of a solid ceramic body with an at least partially metal-coated surface. . The inner part of the locking element may be made of metal, preferably of naobi. The discharge lamp can be provided with an additional hollow ceramic element, a part of the outer surface of which is coated with metal, tightly fixed at the end of the flask. At the free end of the additional ceramic element installed locking element. The outer part of the shut-off element can be made with a protrusion covering the flask. Fig. 1 shows the lamp discharge after melting the solder, but indicating the latter, a cross-sectional view in Fig. 2 — an approximate arrangement of the Parts of the locking element with a scorched ring, the cross section; fig. 3 - the same, after melting of prio; in fig. - an example of the arrangement of parts of the shut-off element of the discharge lamp; Fig. 5 shows the same variant; in Fig. 6, lamp bottom b with an additional hollow element, a section view. The discharge lamp ($ ig.1) consists of a flask 1 made of ceramic or sap-ira with shut-off elements mounted on its ends. The locking element contains an annular part 2 and a disc-shaped inner part 3. Between the inner part 3 and the outer part 2 fitted to it, there is a capillary lumen k located above the end of the wall of the bulb 1. In the inner part 3 a tungsten electrode 6 is fixed by means of an intermediate metal washer 5 with a welded tungsten coil 7. Between the outer part 2. the inner part 3 and the flask 1 there are also capillary gaps 8 and 9 formed by the unevenness of the adjacent surfaces of these parts. The melting process is carried out with the described arrangement by placing a padded ring to on the capillary lumen. The molten solder fills the capillary gaps, 8 and 9, with parts of the locking element remaining stationary during fusion. Discharge lamps (figure 1 and others) are identical, i.e. there are symmetrically formed closures for both ends of the bulb. The lower end of the tube FIG. 1) is shown after the fusion has occurred, where it is seen that the solder penetrated well into the capillary gaps. The manufacture of the discharge lamp is carried out as follows. In one way, one end is sealed. Then the flask 1 is turned upside down with a closed end and a discharge material, for example metallic sodium, is placed in the flask from above, after which the mentioned components of the locking element are placed on the open side of the flask 1. Through the capillary gaps, the 8 and 9 flask 1 is pumped out, preferably under a glass bell. In the atmosphere of an inert gas, the ring is melted under pressure Q-kO Torr, 10. The inert gas remaining in the copeP1 increases the readiness for the ignition of the discharge lamp. After ignition of the inert gas discharge formed in the process, the heat melts the solid material (sodium) and these vapors also enter the discharge. made with a protrusion, with the cylindrical zone of the ceramic outer part surrounding with its large diameter the outer shell of the bulb 1 with the planting which forms a capillary lumen. Similarly, the inner part is made with a ledge resting on the end of the wall of the flask 1. Its outer shell fits under the inner hole of the outer part 2. And the casing of the stepped part of the flask 1. in both cases is formed capillary p | All capillary lumens form an interconnected capillary system. The advantage of a discharge lamp in this embodiment is the increased guarantee that the TO ring does not fall down. The step shape of the outer part 2 facilitates the attachment of the components TOB, which additionally increases the resistance of the tube to constipation to heat losses. . Fig. 3 shows the lamp in a state after the ring 10 has melted. The solder in the capillary gaps is uniform and well distributed. .In FIG. there is no cylindrical part entering the flask. The advantage of this option is the need to precisely fit only one diameter of the part. When using a ceramic body, this provides a considerable advantage. In Fig.5, the locking element has a metal inner part. Preferably niobium or tantalum is used. In the framework of the invention, the manufacture of both locking elements from metal is also not excluded. Fig. 6 shows the structure as a lamer, in which an additional ceramic hollow element 11 is fixed at the end of flask 1 with a metal layer 12 partially applied to its outer surface. Flask 1 and hollow ceramic element 11 are connected via a ring 13 and I to form capillary gaps 15 - 17. The free end of the ceramic hollow element 11 is tightly closed with a locking element, as in figure 2. A constructive solution to ensure the closure of tubular ceramic discharge lamps (Fig. 6) creates a dual current supply at the end of the tube. Through the metal layer 18, the current is supplied to the main electrode 6. The metal layer 12, which is present on the additional ceramic hollow element and passes through the fusion zone inside the bulb, serves as a firing electrode. The invention as a whole makes it possible to simplify the manufacture of discharge lamps and improve their quality. -3 I Yu . , W -2 -6 -7 / 1c Rig. 6
