化させたことを特徴とする投光器。 A light source with an elongated light emitting part is supported horizontally, and the vertical section perpendicular to the light source axis above and on the sides of this light source is a specular reflection formed by a part of a parabola that is focused on the light source axis and opens diagonally forward and downward. A projector covered by a reflective plate having a surface, characterized in that the inclination of the axis of a parabola formed by a longitudinal section of at least a part of the specular reflective surface is sequentially changed along the width direction of the reflective plate. A floodlight.
