Claims

[Scope of utility model registration request]

A box-shaped light body that horizontally supports a light source with an elongated light emitting part inside and is open at the bottom, and a vertical section attached to the light body that is perpendicular to the light source axis is focused on the light source axis and opens diagonally forward and downward. In a floodlight equipped with a reflector having a specular reflection surface formed by a part of a parabola and a transparent cover covering the lower opening of the lamp body, at least a part of the transparent cover is provided with a waveform prism that has a waveform with respect to the light source axis. A floodlight characterized by being installed so as to be oriented diagonally.
