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 |
