PURPOSE:To provide a lighting fixture with snow deposit prevented. CONSTITUTION:An irradiative opening 75 fitted with a lens element 77 is provided in the under-surface of the body 1 of lighting fixture in the form of approximately an inclined eliptical cone, and from this irradiative opening 75, the light from a lamp 22 is emitted for irradiation. Inside of the fixture body 1, the lamp 22, a ballast 31, and a capacitor 41 are installed from the opening 75 side with the aid of a lamp mount 15, a mounting tool 32, and a base board 42, respectively. In the event of much snowfall, the snow slips off from the fixture body by its own weight, and if the snow attches, it is melted due to surface temp. rise of the fixture body 1 caused by heat conduction from the lap 22, stabilizer 31, and capacitor 41, so that deposit on the fixture body 1 can be precluded. |
