Abstract

The invention discloses a ceramic metal halide lamp electrode and a ceramic metal halide lamp. The ceramic metal halide lamp electrode comprises an outgoing line, a connecting rod and an electrode bar, which are sequentially and coaxially connected, wherein molybdenum spirals are wound on the outer surface of the connecting rod; tungsten spirals are wound on the outer surface of the other end part, opposite to the connecting end of the connecting rod, of the electrode bar; the electrode bar is made of zirconium yttrium tungsten alloy formed by zirconium oxide, yttrium oxide and tungsten metal; the total weight percent of zirconium oxide and yttrium oxide is 0.2-3%; the molar ratio of zirconium oxide to yttrium oxide is (1-2.5):1. According to the ceramic metal halide lamp electrode disclosed by the invention, the low current requirement during fast triggering of gas is effectively ensured, so that impact of the high current to a lamp tube is avoided, the service life of the lamp is prolonged, no radioactive contamination is achieved, and high safety and environment protection during production and use are achieved. The ceramic metal halide lamp adopts the ceramic metal halide lamp electrodes as positive and negative electrodes, and is environment-friendly, safe, high in luminous efficiency, good in color rendering index and color temperature, and long in service life.

Description

technical field [0001] The invention belongs to the technical field of lighting and optoelectronics, and in particular relates to a ceramic metal halide lamp electrode and a ceramic metal halide lamp. Background technique [0002] In recent years, the development of ceramic metal halide lamp technology has become more and more mature, the performance parameters have been greatly improved and far surpassed the traditional quartz metal halide lamp in all aspects, and its use has begun to spread rapidly. Even so, the performance of ceramic metal halide lamps has yet to be perfected. [0003] As an important part of the ceramic metal halide lamp, the electrode structure directly affects the performance of the metal halide lamp. At present, the commonly used electrodes for low-power ceramic metal halide lamps in the world can be divided into lead wires (mainly composed of niobium), connecting rods (mainly composed of molybdenum) and electrode rods (mainly composed of thoriated t...
