Abstract

PURPOSE:To enable uniform irradiation by relatively moving a discharge lamp along the surface of the body to be irradiated, which is arranged to oppose apart from the discharge lamp, in the direction of right angle to a light emitting tube. CONSTITUTION:This device has the double-tube structure with internal light emitting tube 1 and external tube 2, and direct tube type metallic halide discharge lamp 3 in which metallic halide such as gallium ionide is sealed inside of the tube 1 together with balance gas of mercury and argon, is supported horizontally by a proper supporting mechanism. Under this discharge lamp 3, the surface of body 4 to be irradiated is provided opposing at an interval. Then, a moving mechanism is so provided that discharge lamp 3 will be moved relatively to the body 4 along the surface of the body 4 in the direction of right angle to internal light emitting tube 1 of discharge lamp 3.
