PROBLEM TO BE SOLVED: To provide a lighting fixture capable of emitting ultraviolet rays from a pointed head to a base of a plant at suitable intensity at any growing-up stage of the plant and capable of reducing production costs.SOLUTION: The lighting fixture 1 includes a plurality of lamps 2. The lamp 2 consists of an irradiation section 13 and a non-irradiation section 14, and includes a linear light-emitting section 9 for emitting ultraviolet rays. Two lamps 2 are rotatably interconnected with a hinge section 3 at these edges in the longitudinal direction. The plurality of lamps 2 can be freely switched between an extending situation where respective light-emitting sections 9 are arranged at an approximately straight line and a folded situation where respective lamps 2 emit light in approximately opposed directions as the non-irradiation sections 14 of respective lamps 2 approach. The lighting fixture 1 can emit ultraviolet rays at suitable intensity from the pointed head to the base of the plant P at any growing-up stage of the plant P by adjusting an irradiation direction of the ultraviolet rays while both lamps 2 are turned each other. Further, production costs can be reduced since the plurality of lamps 2 are collectively installed at one place.COPYRIGHT: (C)2011,JPO&INPIT【課題】照明器具において、植物の何時の成長段階においても植物の先端から根元まで好ましい強度の紫外線を照射できると共に、製造コストを低減できる。【解決手段】照明器具1は、複数の灯具2を備え、灯具2が照射部13と非照射部14で構成されると共に、紫外線を照射する線状の発光部9を収納して成る。灯具2同士は、それら長手方向端においてヒンジ部3により回動自在に連接されている。複数の灯具2は、それぞれの発光部9が略直線状に配置される展開状態と、それぞれの灯具2の非照射部14が近接することで、それぞれの灯具2が略相反する方向に光照射する折畳状態と、に切替自在である。照明器具1は、灯具2同士を回動させて紫外線の照射方向を調整することで、植物Pの何時の成長段階においても植物Pの先端から根元まで好ましい強度の紫外線を照射できる。また、複数の灯具2を1箇所にまとめて設置するので、製造コストを低減できる。【選択図】図1
