Wie erhalte ich diesen Titel?

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 lanthanum tungsten alloy formed by zirconium oxide, lanthanum oxide and tungsten metal; the total weight percent of zirconium oxide and lanthanum oxide is 0.2-3%; the molar ratio of zirconium oxide to lanthanum oxide is (1.8-2.2):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.
