Embodiment 1

[0028] like figure 2 As shown, the present invention discloses a co-fired and sealed high-efficiency ceramic lamp, which includes a discharge chamber 11 and an electrode tube 12 arranged at the end of the discharge chamber 11. The electrode tube 12 is inserted with a ceramic metal electrode 13, and the ceramic metal electrode 13 is connected to a tungsten electrode 14 near the end of the discharge chamber 11, wherein the ceramic metal electrode 13 and the electrode tube 12 are sealed by co-firing.

[0029] In this embodiment, the end of the ceramic metal electrode 13 and the corresponding part of the electrode tube 12 are co-fired and sealed. Of course, the ceramic metal electrode 13 can also be co-fired and sealed with the entire electrode tube 12 .

[0030] The outer diameter of the ceramic metal electrode 13 matches the inner diameter of the electrode tube 12. Compared with the sealing method using solder, the contact area between the co-fired arc tube and the ceramic met...

Embodiment 2

[0037] The structure of this embodiment is similar to that of Embodiment 1, the difference is that the metal lead is a separate component, such as image 3 As shown, the end of the cermet electrode 13 is also connected with an anti-oxidation metal lead 15, and a welding groove 16 is also provided between the end of the electrode tube 12 and the end of the cermet electrode 13, and the metal lead 15 extends through the welding groove 16. Out of the electrode tube 12, the welding groove 16 is used for filling glass solder. Wherein, the diameter of the metal lead wire 15 is smaller than that of the cermet electrode 13 .

[0038] In the above scheme, in order to prevent the oxidation of the cermet electrode 13, an anti-oxidation metal lead wire 15 is connected to the end of the cermet electrode 13, and the end of the cermet electrode 13 is shorter than the end of the electrode tube 12, and then the end is melted with glass solder to cover the cermet electrode 13 to prevent oxidati...

Abstract

A co-firing sealing ceramic lamp and a preparation method thereof are disclosed. The co-firing sealing ceramic lamp includes a discharge cavity (11) and an electrode tube (12) arranged at an end part of the discharge cavity. A ceramic metal electrode (13) is inserted in the electrode tube; one end, close to the discharge cavity, of the ceramic metal electrode is connected with a tungsten electrode (14); the ceramic metal electrode and the electrode tube are sealed by co-firing. The co-firing sealing ceramic lamp can effectively avoid the corrosion of the solder, and has better gas tightness.

Description

technical field [0001] The invention belongs to the field of ceramic light sources, in particular to a high-efficiency co-fired and sealed ceramic lamp and a preparation method thereof. Background technique [0002] The ceramic lamp structure is directly related to the sealing process. Sealing is the key technology of ceramic discharge light source, and the quality of the sealing is directly related to the performance and life of the arc tube. The sealing technology of ceramic discharge tubes is different from that of quartz. Quartz metal halide lamps are shrink-sealed or compressed-sealed by melting quartz and electrodes or electrode assemblies. Ceramics should not be melted after molding. The sealing of ceramics and electrodes or electrode assemblies is It is completed by filling the gap between the ceramic and the electrode with glass solder, see figure 1 As shown, it includes the discharge chamber 6, the electrode tubes 2 located at both ends of the electrode tube and ...
