Problems solved by technology

This puts forward high requirements on the quality of tungsten glass materials. The production technology of this kind of tungsten glass is mastered by a few foreign manufacturers, which is not conducive to the export of xenon lamps produced in my country, and those produced in my country are used to match electrodes. The product characteristics of the encapsulated glass material cannot be compared with it. Using the same encapsulation process, due to the encapsulation glass material, the quality of the product often lags behind that of the latter, and it is prone to cold explosion and thermal explosion, and its service life cannot reach that of foreign counterparts.

Embodiment Construction

[0016] Such as figure 1 A transition-sealed xenon lamp shown includes a quartz glass shell 1 and an electrode 2 inside the quartz glass shell 1. A valveable ring 3 is arranged on the electrode 2, and the electrode 2 passes through the valveable ring 3, the valveable glass 4 and the transition The glass connecting body 5 is connected to the quartz glass shell 1 , the valve ring 3 and the valveable glass 4 are packaged in a matching manner, and the valveable glass 4 and the quartz glass shell 1 are sealed and connected through the transition glass connecting body 5 . The expansion coefficient of the valveable glass 4 is small, which is similar to ordinary glass. It is often used in the packaging of electronic tubes, ceramic packaging semiconductor power, and high-frequency devices. It is a commonly used material for electrodes passing through glass such as electronic tubes. The materials of the valveable ring 3 and the valveable glass 4 have the same expansion coefficient, so th...

Abstract

The invention relates to the field of high-powder xenon lamp technology, particularly to an intermediate sealing xenon lamp, comprising a quartz glass casing and an electrode in the quartz glass casing, the electrode is provided with a Kovar ring connected with the quartz glass casing by Kovar glass and intermediate sealing connector, the Kovar ring and the Kovar glass are matchedly sealed and have same swell factor, therefore gas leakage phenomena hardly occurs. Compared with the old structure in which bubble, molybdenum foil and quartz glass casing are unmatchedly sealed, the air outlet of the xenon lamp can be arranged on a tail tube, so that the casing of the xenon lamp is kept smooth. The smooth spherical casing is uneasy to generate stress when the xenon lamp glows, thus to avoid lamp explosion.

Description

technical field [0001] The invention relates to the technical field of high-power xenon lamps, in particular to a transition sealing type xenon lamp. Background technique [0002] Xenon lamp is a short-arc spherical point light source, so it has the characteristics of high brightness, especially there is a very bright cathode spot near the cathode light. If this spot can be used in the design of the reflective bowl, high brightness and high brightness can be obtained. efficiency effect. Its spectral distribution characteristics are very similar to sunlight, and have the same color temperature and color rendering index as sunlight, so it is widely used in: 1. Movie and TV shooting; 2. Movie projection; 3. Stage follower lighting ; 4. Solar simulators in military and aerospace fields; 5. Used in material aging tests; 6. Artificial climate chamber. [0003] The original xenon lamp sealing technology is to use air bubbles, molybdenum foil and quartz glass shell non-matching se...
