Abstract

Provided is a ceramic halogen lamp electrode that comprises a leading-out wire, a connecting rod, and an electrode bar. The leading-out wire and the electrode bar are connected with the two ends of the connecting rod, respectively. The material of the electrode bar comprises tungsten, hafnium oxide, and yttrium oxide. The total percentage content, by mass, of the hafnium oxide and the yttrium oxide in the electrode bar is from 0.2 to 3 percent. The mass ratio of the hafnium oxide to the yttrium oxide is between 0.9 to 1 and 2.8 to 1. The ceramic halogen lamp electrode causes no radioactive contamination. The invention also provides a ceramic halogen lamp.

Description

technical field [0001] The invention relates to a ceramic metal halide lamp electrode and a ceramic metal halide lamp using the ceramic metal halide lamp electrode. Background technique [0002] The electrodes of ceramic metal halide lamps include lead wires, connecting rods and electrode rods, which are respectively connected to both ends of the connecting rods, and the lead wires, connecting rods and electrode rods are coaxial with the electrode rods as the start or end of the discharge arc. , has anti-halide chemical corrosion at high temperature; the lead wire and the sleeve of the ceramic arc tube have similar thermal expansion coefficients, which play the role of hermetic sealing; and the connecting rod not only plays the role of connecting the electrode rod and the lead wire, but also acts as a To avoid the effect of halides on the lead-out wire corrosion. [0003] The material of the electrode rod is usually thoriated tungsten alloy. The addition of thorium can redu...
