    摘要: A high pressure sodium lamp comprises an elongated arc tube within an evacuated outer jacket, the arc tube containing a fill including sodium and mercury. A barium getter film is disposed on the inner jacket wall at one end thereof. The film is longitudinally spaced more than 1 cm away from the end of the arc tube in order to reduce photoelectron emission from the barium which can cause sodium migration from the arc tube.

    摘要: The alumina arc tube of a high pressure sodium arc discharge lamp has a multiple turn wire starting aid wound therearound in order to reduce lamp starting voltage. The starting aid must extend longitudinally along the arc tube for a distance that is at least 10% of the arc length of the arc tube.
