    摘要: A starting aid for a metal halide discharge lamp. An arc discharge tube is positioned in a hermetically sealed jacket. The jacket contains a partial pressure (e.g., 400 torr nitrogen) of a gas that will aid in starting the discharge and one of the arc tube lead-ins has an electrical conductor affixed thereto and exposed to the partial pressure of the gas. An outer conductor extends on the outside of the jacket and is electrically connected to the other lead-in. When voltage is applied to the electrodes a capacitive coupling takes place between the inner conductor and the outer conductor which generates a discharge that causes a breakdown in the arc generating and sustaining medium within the arc tube and causes the lamp to start.
