Abstract

PURPOSE: To efficiently radiate ultraviolet rays to a material with the photocatalyst action by providing the material with the photocatalyst action on part of the outer surface of the discharge container of a discharge lamp radiating ultraviolet rays.
CONSTITUTION: A material 2 with the photocatalyst action is directly provided on the outer surface of the discharge container 1 of a discharge lamp radiating ultraviolet rays, e.g., the material with the photocatalyst action is formed into a powder shape and coated on the outer surface of the discharge lamp radiating ultraviolet rays. Ultraviolet rays emitted from discharge plasma pass through the wall of the discharge container 1 and directly act on the material 2 having the photocatalyst action and provided on the outer surface of the discharge container 1. The light emitted from the discharge lamp can be efficiently utilized.
