Abstract (en)
A lighting device may readily be installed in low cost. A lighting sleeve body 9 is rotatably mounted on a horizontal upper edge portion 4b of a sleeve-like mounting base 4 mounted on a roof. The lighting sleeve body 9 may be drivingly rotated in response to a position of the sun by a lighting sleeve body rotary drive mechanism 17 on the horizontal upper edge portion 4b of the mounting base 4. A plurality of reflector plates 19 are disposed rotatably around horizontal shafts 20 to reflect the sunshine within a lighting opening portion 9a at a slanted upper portion of the lighting sleeve body 9 and introduce lights into the interior of the room through inner passages 9b and 4c of the lighting sleeve body 9 and the mounting base 4. A reflecting angle of the reflector plates 19 may be changed in response to the position of the sun by a reflector plate rotary drive mechanism 27. <IMAGE>
