Embodiment Construction

[0017] A ceramic metal halide lamp electrode, a main rod 1 made of thorium-tungsten alloy material, one end of the main rod is wound with a yttrium-molybdenum alloy wire helix 2, and the other end of the main rod is wound with a high-purity tungsten wire helix 3; The end of the main rod at one end of the helix is ​​connected with the niobium rod 4 of the outer lead.

[0018] The gap between adjacent spirals in the yttrium-molybdenum alloy wire spiral body and the high-purity tungsten wire spiral body is less than 0.005mm. The sum of the lengths of the yttrium-molybdenum alloy wire helix and the high-purity tungsten wire helix accounts for more than 70% of the total length of the main rod. Mosaic welding between the niobium rod and the main rod of the outer lead: first process the end surface of the niobium rod with a deep arc-shaped indentation 5 of 0.2mm, and then the main rod and the spring contact the inner hole of the lead end with a large area and then energize and weld. ...

Abstract

The invention discloses a ceramic metal halogen lamp electrode which comprises a main rod made of thorium-tungsten alloy materials; a yttrium-molybdenum alloy-wire spiral body is wound on one end of the main rod, and a high-purity tungsten wire spiral body is wound on the other end of the main rod; and the main rod end part on which the yttrium-molybdenum alloy-wire spiral body is wound is connected with an outer-lead niobium rod. The invention is a high-effective and environment-friendly ceramic metal halogen lamp electrode and has the advantages of high efficiency, safety, environment protection, even electrode spring, and the like.

Description

Technical field: [0001] The invention relates to an electrode, which is an electrode of a ceramic metal halide lamp. Background technique: [0002] The electrodes of the existing ceramic metal halide lamps have low working efficiency, have radiation and cause harm to people, and have an unreasonable structure. Invention content: [0003] The object of the present invention is to provide a ceramic metal halide lamp electrode that is safe, environment-friendly and has good working performance. [0004] Technical solution of the present invention is: [0005] A ceramic metal halide lamp electrode, which is characterized in that: a main rod made of thorium-tungsten alloy material, one end of the main rod is wound with a yttrium-molybdenum alloy wire helix, and the other end of the main rod is wound with a high-purity tungsten wire helix; The end of the main rod at one end of the alloy wire helix is ​​connected with the niobium rod of the outer lead. [0006] The gap between...
