Abstract
PURPOSE:To improve the efficiency and to make suitable for the mass production by multiple sealing a planar cover container made of crystalline ceramic to a glass container having a zigzag path. CONSTITUTION:An intergrated pan-shaped glass container 2 having a partitioning wall 3 and a zigzag path and a planar cover container 4 made of crystalline ceramic having good reflective characteristic for the visible light are formed, and after applying the phosphor material on the inner face said glass container 2 and the planar cover container 4 are multiple sealed. Thereafter the gas is exhausted through an exhaust tube 7 and the electrode 5 is activated, then small amount of mercury and the rare gas such as neon, argon, krypton, etc. are filled and the exhaust tube 7 is encapsulated.
