GAS PROBE STARTER FOR ELECTRODELESS HIGH LUMINOUS-INTENSITY DISCHARGE LAMP

摘要

PURPOSE: To reduce required voltage for starting arc discharge by possessing a means removing gas-like impurity from the filling of an ignition chamber. CONSTITUTION: A gas probe ignition device 12 for an electrodeless HID lamp is equipped with a getter removing gas-like impurity from filling loaded in the ignition chamber 34 of a gas probe ignition device. In a favorable example, a metal thin piece 50 possesses sintered powder-like active getter material disposed on the surface thereof, and the metal thin piece is inserted into the most suitable position in an ignition chamber depending on the most suitable operation temperature of specified getter material.
