However, such a conventional configuration has the following problems. That is, regarding the inner surface of the housing 1, each point where a straight line connecting the center of the housing 1 and the center of each pipe 6 intersects the inner surface of the housing 1, that is, each point where the inner surface of the housing 1 is closest to each pipe (on the solid line) is a line along the longitudinal direction of the pipe 6, but for convenience of explanation, the third point P is a line along the longitudinal direction of the pipe 6.
(shown in the figure), the ultraviolet rays emitted from each lamp 7 are interfered with by the adjacent lamps 7 or their pipes 6, and cannot reach the point P corresponding to the adjacent lamps 7. , the overall irradiation efficiency of ultraviolet rays to this point P was poor, in other words, there was a problem that the ultraviolet rays from each lamp 7 were not effectively utilized.
