PURPOSE:To provide a lighting equipment preventing the leak of a noise generated in a ballast. CONSTITUTION:An equipment body 1 is formed into a box and has an emitting opening 2 formed on the lower surface. A reflector 4 having a reflecting surface form on the lower surface is mounted on the equipment body 1. Straight fluorescent lamps 5, 5 are mounted in parallel to each other optically opposite to the reflector 4. A lattice-like louver 8 is mounted on the emitting opening 2, and a light permeable plate body 9 is mounted on the lower side of the louver 8. The noise generated in a ballast 3 is reflected by the light permeable plate 9 to prevent the leak of the noise of the ballast 3 from the emitting opening 2 of the equipment body 1. |
