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 dysprosium tungsten alloy; the weight percent of dysprosium is 0.2-3%. The ceramic metal halide lamp electrode disclosed by the invention has no radioactive contamination, is safe and environment-friendly; meanwhile, the electrode bar is made of dysprosium tungsten alloy, so that electron removal of the metal halide lamp electrode is reduced, working temperature of the electrode is effectively recued and the service life of the electrode is prolonged. 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 of low-power ceramic metal halide lamps in the world are as follows: figure 1 As shown, it includes lead-out wire 01 (mainly composed of niobium), connecting rod 02 (mainly composed of molybdenum) and electrode r...
