PURPOSE:To facilitate an easy change of the light distribution and to increase the general-purpose properties of a reflecting plate member, by selectively connecting the 1st reflecting plate member to either one of the junction edge bars provided opposite to each other at a U-shaped connecting part of the 2nd reflecting plate member. CONSTITUTION:For a reflecting plate device 5, a junction edge bar 10 of a reflecting plate member 6 is inserted through a U-shaped connecting part 13 of a reflecting plate member 7 to touch a junction edge bar 16 of the outside. Then a coupling screw 17 inserted through an insertion/hook hole 19 of the bar 10 is screwed into a screw hole 9 to touch close the inner side of the bar 16. The device 5 having such constitution is set into a main body 1, and other edge fixing bars 11 and 20 of the members 6 and 7 are fixed to attachment bars 26 and 27 by screws 28 respectively. The distribution of light can be increased by attaching the bar 10 of the member 6 so far touching the bar 16 of the member 7 to a junction edge bar 14 and fixing them with the screw 17. Furthermore the distribution of light can be controlled by selecting the bar 14 or 16. |
