Abstract
The fluorescent lighting fixture includes a protective tube having a roulette configuration dented portions of which extend longitudinally and a rib having a long hole in which a wire is inserted. The roulette configuration appears as a stripe pattern on the protective tube and the wire inserted in the hole becomes less noticeable. When the fluorescent lamp is set alight, the light reflects, the entire protective tube becomes luminous uniformly, and the wire becomes hard to be seen. The wire can be invisible without an extra part such as a screening plate, and sufficient luminous intensity can be obtained from the entire protective tube.
