Abstract

PURPOSE:To better the rate of luminous flux maintenance and the initial voltage of discharge by using a specific electron-radiating substance. CONSTITUTION:The double coil 1 in contact with the electrode core bar 4 is provided with the single coil 2 on its outside and then coated with the electron-radiating substance 3 which is obtained by adding 10-40mol% zirconium oxide to a mixture of 50mol% barium oxide and 50mol% calcium oxide and yttrium oxide.
