Abstract

The invention relates to a ceramic metal halide lamp and its electrode assembly. Wherein, the electrode assembly is four-member structure with axis core on one straight line, and comprises from inner to outer, a tungsten-made electrode, a transition molybdenum wire with ends welding to former electrode and niobium lead wire end in arc tube, and a niobium lead wire with diameter over the outside diameter of molybdenum screws set on top of molybdenum wire and electrode respectively. In the preparing process, resistance welding the molybdenum wire and lead wire, setting the screw on molybdenum wire, and inserting the electrode rod into the screw. This invention forms an integrated structure.

Description

technical field [0001] The invention relates to the technical field of lighting appliances, in particular to a preparation process of a ceramic metal halide lamp and an electrode assembly thereof. Background technique [0002] Ceramic metal halide lamps are a new generation of metal halide lamps successfully developed in the middle of the 1990s. They have the characteristics of high light efficiency, good color rendering performance, stable light color and long life. They are the most ideal lighting effects. High-intensity gas discharge light source can significantly save energy, reduce environmental pollution, and improve people's lighting quality, so it has become a hot spot pursued by lighting manufacturers and users. [0003] The electrode assembly is one of the key parts of the ceramic metal halide lamp. Whether its design structure is reasonable and whether the manufacturing process is easy is directly related to the performance, life and reliability of the lamp. A lot...
