Abstract

A discharge lamp has a lamp assembly including a discharge lamp unit with a pair of lamp leads extending therefrom, and a base assembly including a pair of base leads electrically connected to the pair of lamp leads and mechanically supporting the lamp unit in position with respect to the base assembly. The base assembly comprises a hollow base structure of electrically insulating material molded in one piece with a partition dividing the interior thereof into a pair of completely isolated spaces. Electrically connected to the base leads, a pair of sheet metal conductors are received with clearances in the respective isolated spaces in order to preclude the possibility of an electric discharge taking place between the pair of conductors within the base structure.
