PROBLEM TO BE SOLVED: To easily support a lamp device and facilitate the layout change thereof by mounting a plurality of lamp device support metal fittings on a horizontal lamp device mounting rail mounted on a showcase or the like, and forming lamp device support parts in two front and rear lines on the lamp device support metal fittings. SOLUTION: The upper horizontal locking part of a lamp device support metal fitting 11 is inserted to the opening on the lower surface of a C-shaped sectional lamp device mounting rail 10 from the lower surface side with its long edge being turned in the lateral direction of the lamp device mounting rail 10. When the lamp device support metal fitting 11 is horizontally rotated 90 deg. in this state, the long edge gets on the horizontal protruding part, and the lamp device support metal fitting 11 is supported within the lamp device mounting rail 10. At least two lamp device support metal fittings 11 are moved and arranged in optional positions of the lamp device mounting rail 10, lamp device 5 is placed one by one on the horizontal part of the front and rear lamp device support parts 11b of the lower part, and straight tube fluorescent lamps 12 are mounted thereon, respectively. Thus, the continuity of light can be ensured by using long fluorescent lamps to eliminate the lighting unevenness, and the number of fluorescent lamps to be used can be also reduced to suppress the cost. |
