Abstract

The invention discloses a metal halide lamp electrode and a ceramic metal halide lamp. The metal halide lamp electrode comprises a tungsten electrode stem and a molybdenum plate. One end of the tungsten electrode stem is coaxially and electrically connected with the molybdenum plate, and a tungsten filament spiral device is wound around the outer surface of the other end. A plurality of transmitting balls are arranged between adjacent spiral tungsten filaments of the tungsten filament spiral device in a sandwiched mode, wherein the transmitting balls are spherical or approximately spherical. Each transmitting ball is composed of, by weight, 0.05-0.5% of hafnium oxide, 0.5-3% of lanthanum oxide, 0.05-10% of samarium oxide, and the balance tungsten. The electron work function of the metal halide lamp electrode is low, the working temperature of the electrode is effectively lowered, evaporation and growth of tungsten metal are restrained, the stability of a tungsten prill structure is ensured, the service life is long, and the light-emitting efficiency is high; as metal halide lamp electrodes serve as positive and negative electrodes of the ceramic metal halide lamp, the ceramic metal halide lamp is environmentally friendly, safe, high in luminous efficiency 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 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. Among them, the commonly used electrode structures for medium-power ceramic metal halide lamps are as follows: figure 1 As shown, it mainly includes a molybdenum sheet (molybdenum foil) 02. The molybdenum sheet 02 has two opposite ends, one end of which is coax...
