PURPOSE:To enable variable light distribution at will for the purpose of illuminating parks and station squares by installing a plurality of reflective plates, whose lower faces are constituted into reflective faces, near the upper end of an illumination pole at freely variable angle and installing an luminaire under the plates. CONSTITUTION:A plurality of reflective plates 13 supported by a reflective plate supporting body 12 are installed neat the upper end of a hollow cylindrical illumination pole 11 in the way the installation angle can be changed freely. The angle of each reflective plate 13 can be set independently. The lower face of a reflective plate is composed as a reflective face using A or by applying a white paint. The distribution of light from the luminaire below can be changed corresponding to the purpose by changing the angle of the reflective plates 13 through a tensile body 14, a pulley 15, a hinge 17, and a motor 16. |
