<p>A fluid purification device including an inverted U-shape frame whose legs (7, 16) support a plurality of lamp assemblies each including an ultraviolet lamp (14) received in a protective sleeve (15). One of the legs (17) is hollow and receives lead wire(s) (11) connected to the lamps through openings (35) spaced along the leg (7). The protective sleeve (15) at one of their ends are resiliently mounted to the hollow leg (17) at the openings (35), and seals (9) are provided to prevent fluid from entering into the hollow leg (7) and the protective sleeve (15). The other ends (15a) of the protective sleeves (15) are closed and held in receptacles in the other frame leg (16) which is formed by two plates (16a, 16b) fixed to each other. "O" rings (17) provided along the other leg (16) receive the protective sleeves (15) to provide flexible seats. An electrical ballast (2) controlling amperage and/or voltage at the lamps (14) is incorporated in the frame.</p> |
