Patent ID: 10861691

Abstract:
The present disclosure relates to the technical field of electric light sources, particularly to a metal halide lamp and a manufacturing method thereof. The metal halide lamp includes an electric arc tube, an inner glass bulb, and a lamp holder fixedly connected with the inner glass bulb; the electric arc tube includes a tube body, a positive electrode located inside an electric arc cavity of the tube body and connected with a positive feedthrough inserted in a first leg portion of the tube body, and a negative electrode connected with a negative feedthrough inserted in a second leg portion of the tube body; the electric arc cavity is provided therein with an ignition gas; an outer surface of the first leg portion is provided with a conductive layer and a metal electrical connector, wherein the conductive layer has one end close to and the other end away from an electrode tip of the positive electrode, the metal electrical connector has one end connected with the other end of the conductive layer, and the other end connected with a long molybdenum rod. Security risks in manufacturing, transportation, mounting, utilization, storage, and waste disposal brought about by use of the radioactive material 85Kr are avoided in the present disclosure.
