ABSTRACT:
A dielectric barrier discharge type low pressure discharge lamp11includes dielectric barrier discharge type external electrodes21, 22on external ends of a tubular glass lamp vessel10, electrically conductive material layers31, 32on the external surface of the tubular glass lamp vessel, and heat equalizing members41, 42, which are provided on the electrically conductive material layer. With the constitution, the surface temperature of the external electrodes21, 22can be equalized with a local temperature rise avoided, thereby a longer life of the lamp can be assured.
