<P>PROBLEM TO BE SOLVED: To provide a lighting fixture equipped with a variant reflective mask capable of especially applying to a road, an advertising signboard, and a production line or the like and converting light from a light source into an effective illumination light and effectively utilizing electric power. <P>SOLUTION: The lighting fixture equipped with a variant reflective mask includes at least the light source for generating light, and the variant reflective mask. The variant reflective mask internally has the light source, the rear face of the variant reflective mask is a reflective surface, two side faces of the variant reflective mask are swelling arc faces, and each swelling arc face is formed by connecting a plurality of partially-conical faces which respectively have different inclination angles. The inclination angle of each partially-conical face is inclined to the center of the variant reflective mask as it goes closer to an upper part of the variant reflective mask, the width of the expanded arc face becomes narrower gradually from a bottom to the upper part, an upper face of the reflective mask is a concave upper face, and one side of the concave upper face is formed by connecting the plurality of partially-conical faces wherein inclination angles to a lower part are different each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
