Abstract
PURPOSE:To prevent the slow leak of the encapsulated gas through the brazed joint, by forming the metal casing with such metal as having the thermal expansion factor approximately same with that of a ceramic casing containing the reflection face while fixing a cooling heat transmission element having the heat pipe structure. CONSTITUTION:The high brightness discharge lamp is comprised of a high brightness discharge lamp 1 and a cooling heat transmission element 2. The high brightness discharge lamp 1 is constructed such that a reflection surface 5 is provided in a ceramic casing 4 closed at one end with an optical sealing window 3 then gas is encapsulated, then a gap (g) is formed approximately at the focus of the reflection surface 5 to provide the facing anode 6 and cathode 7, thereafter metal casings 8, 9 having the thermal expansion factor approximately same with that of the ceramic casing 4 are brazed separately to the ceramic casing 4.
