  As shown in FIGS. 1 and 2, the instrument body 11 is formed by pressing a relatively thin metal plate member or the like, and is arranged to face the top plate 16 in the longitudinal direction of the instrument body 11. It has a pair of end plates 17 and a pair of side plates 18 arranged opposite to each other in the width direction perpendicular to the longitudinal direction of the instrument body 11 and opens downward. A ballast 19 and a power supply terminal block 20 are attached to the instrument body 11 at the center of the lower surface of the top plate 16 in the longitudinal direction and the width direction perpendicular to the longitudinal direction. A pair of medium reflector mounting springs 21 are respectively attached to the main body 11 of the ballast 19 and the power terminal block 20 on the outer side in the longitudinal direction of the main body 11. The instrument body 11 is provided with a pair of mounting bolt holes 22 in the longitudinal direction of the central portion in the width direction on the lower surface of the top plate 16 and a pair of temporary hanging strap hooks 23 near the end plate 17 in the longitudinal direction. A single power line insertion hole 24 is provided in the vicinity of the power terminal block 20.

  A pair of mounting bolts 2 projecting from the ceiling construction surface 1 toward the floor surface are inserted into the mounting bolt holes 22 of the appliance main body 11. Then, when the nuts 26 are screwed into the mounting bolts 2 through the washers 25, the instrument body 11 is assembled in contact with the ceiling construction surface 1. The temporary hanging string hooking portion 23 is formed so as to protrude downward into a V-shaped plate shape by cutting and forming the top plate 16.

  The power line 3 is drawn into the power line insertion hole 24 from the ceiling construction surface 1 side. The power line 3 is connected to a commercial power source through a control circuit (not shown) and is electrically connected to the power terminal block 20. In-apparatus wiring (see FIG. 5) 28 is routed from the power supply terminal block 20 to the lamp socket 27 through the ballast 19 and electrically connected thereto.

  The middle reflection plate mounting spring 21 is disposed so as to protrude downward from the top plate 16 of the instrument body 11 in a C shape. The middle reflector mounting spring 21 is elastically deformed so that the C-shaped portion expands when inserted into the two pairs of locking holes 29 formed in the middle reflector 14, and then accumulates in the C-shaped portion. The intermediate reflecting plate 14 is held so as to be pressed toward the top plate 16 of the instrument body 11 by the elastic restoring force. Two pairs of lamp sockets 27 are attached to the appliance body 11 so as to face each other inside the end plates 17. The louver 13 is formed in a blade shape using a relatively thin metal plate member similar to the instrument body 11. The louver 13 has a width dimension smaller than the distance dimension formed by the both side plates 18 of the instrument main body 11, and has a predetermined height dimension that the center part is large and the both side parts are small.

  The middle reflecting plate 14 is formed in a V shape using a relatively thin metal plate member similar to the louver 13. The middle reflecting plate 14 has a middle reflecting plate body 30 having a length dimension smaller than the interval dimension formed by the both end plates 17 of the instrument body 11, and the middle reflecting plate is attached to both ends of the middle reflecting plate body 30. A pair of locking holes 29 for locking the spring 21 is formed. The middle reflecting plate 14 has bent end edges 31 that are bent at an acute angle at both ends of the middle reflecting plate body 30.

  The middle reflecting plate 14 includes a pair of sub-reflecting plates 32 on both outsides. The middle reflection plate 14 has a space 33 inside the middle reflection plate main body 30. Therefore, the intermediate reflector 14 is attached to the instrument body 11 via the intermediate reflector attachment spring 21, so that the stabilizer 19, the power terminal block 20, the attachment bolt 2, the washer 25 and the nut 26, the power supply line 3, the instrument Each of the inner wire 28, the temporary hanging strap hook 23, and the temporary hanging strap 15 is accommodated in the space 33 so that it cannot be directly viewed from the floor side.

  The temporary hanging strap 15 is formed in a predetermined and sufficiently long length, has a metal hook portion 34 having an S-shape at one end portion, and the other end portion is bound to the medium reflecting plate 14. Yes. The temporary hanging strap 15 is connected to the instrument main body 11 by hooking the hook portion 34 to the temporary hanging strap hooking section 23 of the instrument main body 11. When the temporary hanging strap 15 is installed on the ceiling construction surface 1 or when the fluorescent lamp 12 is replaced, the intermediate reflector 14 having the louver 13 and the sub reflector 32 is removed from the intermediate reflector attachment spring 21. When it is removed, it has a function of suspending the intermediate reflector 14 at a position away from the lower part of the instrument body 11.

  As shown in FIGS. 3 and 4, the instrument body 11 has a protrusion 35 formed on the lower surface of the top plate 16. The protrusions 35 are formed at four locations corresponding to positions where the mid-reflection plate 14 in the vicinity of the lamp socket 27 is attached on the lower surface of the top plate 16 of the instrument body 11. The protrusions 35 may be provided at a plurality of locations in the portion corresponding to the bent end edge portion 31 of the intermediate reflecting plate 14 in the top plate 16 of the instrument body 11 in place of the four locations in the vicinity of the lamp socket 27. . In FIG. 4, the protrusion 35 is formed in a substantially hemispherical shape in which the Y direction, which is the width direction orthogonal to the longitudinal direction of the instrument body 11, is longer than the X direction, which is the longitudinal direction of the instrument body 11, toward the floor surface. It is protruding. The protrusion 35 has a divergent convex inclined surface 36 having a gradient that increases with respect to the mounting direction of the intermediate reflector 14 in each of the upper and lower cross-sectional directions of the instrument body 11 and the longitudinal direction of the instrument body 11. The protrusion 35 is preferably selected in consideration of workability, such as a triangular pyramid or a quadrangular pyramid, instead of a substantially hemispherical shape.

  As shown in FIGS. 5 and 6, the appliance main body 11 is provided with an appliance wiring 28 along the lower surface of the top plate 16 between the ballast 19 and the lamp socket 27. The protrusion 35 is set such that the height dimension L <b> 1 from the top plate 16 of the instrument main body 11 is larger than the diameter dimension D <b> 1 of the in-appliance wiring 28.

  In attaching the intermediate reflector 14 to the instrument body 11, the intermediate reflector 14 accumulates in the intermediate reflector attachment spring 21 when the locking hole 29 of the intermediate reflector 14 is engaged with the intermediate reflector attachment spring 21. The elastic restoring force is pulled toward the top plate 16 of the instrument body 11. At this time, if the in-instrument wiring 28 is routed in the X direction (see FIG. 4) with respect to the protrusion 35 and rides near the top of the protrusion 35, it is accumulated in the intermediate reflector mounting spring 21. Due to the elastic restoring force, the bent end edge 31 of the intermediate reflecting plate 14 presses the in-appliance wiring 28 riding on the vicinity of the top of the protrusion 35 upward. As a result, the in-appliance wiring 28 pressed upward is guided smoothly by the inclined surface 36 of the protrusion 35 without being caught from the vicinity of the top of the protrusion 35 toward the left side of the protrusion 35 in FIG. Moved to.

  Then, after the intra-apparatus wiring 28 is moved from the vicinity of the top of the protrusion 35, the bent end edge 31 of the intermediate reflector 14 is brought into contact with the top of the protrusion 35, whereby the intermediate reflector 14 and the instrument main body 11 are brought into contact with each other. The distance from the top plate 16 is set constant. At this time, since the height dimension L1 of the projection 35 from the top plate 16 of the instrument main body 11 is set larger than the diameter dimension D1 of the in-apparatus wiring 28, the intermediate reflecting plate 14 in contact with the top of the projection 35 is provided. The bent end edge 31 is arranged in a non-contact manner on the in-tool wiring 28.

  As shown in FIGS. 7 and 8, when the intermediate reflector 14 is pulled in the direction approaching the top plate 16 of the instrument body 11 by the elastic restoring force accumulated in the intermediate reflector attachment spring 21, When the inner wiring 28 is routed in the Y direction (see FIG. 4) with respect to the protrusion 35 and rides on the vicinity of the top of the protrusion 35, the inner reflection is caused by the elastic restoring force accumulated in the intermediate reflector mounting spring 21. The bent edge portion 31 of the plate 14 presses the in-appliance wiring 28 riding on the vicinity of the top of the protrusion 35 upward. Accordingly, the in-appliance wiring 28 pressed upward is guided smoothly by the inclined surface 36 of the protrusion 35 and is not caught in the direction of the right side of the protrusion 35 in FIG. Moved to.

  Then, after the intra-apparatus wiring 28 is moved from the vicinity of the top of the protrusion 35, the bent end edge 31 of the intermediate reflector 14 is brought into contact with the top of the protrusion 35, whereby the intermediate reflector 14 and the instrument main body 11 are brought into contact with each other. The distance from the top plate 16 is set constant. At this time, since the height dimension L1 of the projection 35 from the top plate 16 of the instrument main body 11 is set larger than the diameter dimension D1 of the in-apparatus wiring 28, the intermediate reflecting plate 14 in contact with the top of the projection 35 is provided. The bent end edge 31 is arranged in a non-contact manner on the in-tool wiring 28.

  As described above, the middle reflecting plate 14 is attached to the instrument main body 11 without being inclined with respect to the top plate 16 of the instrument main body 11 by the bent end edge portion 31 coming into contact with the tops of the protrusions 35. At this time, since the height dimension L1 of the projection 35 from the top plate 16 of the instrument main body 11 is set larger than the diameter dimension D1 of the in-apparatus wiring 28, the intermediate reflecting plate 14 in contact with the top of the projection 35 is provided. The bent end edge 31 is arranged in non-contact with the in-appliance wiring 28.

  The intermediate reflector 14 is attached to the instrument main body 11 in a non-contact manner with respect to the in-apparatus wiring 28 by the bent end edges 31 coming into contact with the respective tops of the protrusions 35. The in-instrument wiring 28 is visually observed from the gap between the 14 bent edge portions 31 and the top plate 16 of the instrument body 11. However, since the opening direction of the gap is the plate surface direction of the top plate 16 of the instrument body 11, it cannot be visually observed from the floor. Therefore, it will not detract from the beauty.

Therefore, in the lighting apparatus 10 of this embodiment, when the in-apparatus wiring 28 runs on the vicinity of the top of the protrusion 35, the folding of the intermediate reflector 14 is performed by the elastic restoring force accumulated in the intermediate reflector mounting spring 21. The curved edge portion 31 presses the in-instrument wiring 28 toward the top plate 16 of the instrument body 11.
Thereby, in the lighting fixture 10 of this embodiment, the in-apparatus wiring 28 is moved to a position away from the protrusion 35 by the intermediate reflecting plate 14 and is sandwiched between the intermediate reflecting plate 14 and the appliance main body 11. Because there is no aesthetics can be improved.

Moreover, in the lighting fixture 10 of this one Embodiment, the protrusion 35 has the convex-shaped gradient which spreads toward the end.
Thereby, in the lighting fixture 10 of this one embodiment, the in- fixture wiring 28 pressed by the bent end edge portion 31 of the intermediate reflector 14 can be smoothly moved without being caught by the gradient.

And in the lighting fixture 10 of this one Embodiment, the height dimension L1 from the top plate 16 of the instrument main body 11 of the protrusion 35 is larger than the diameter dimension D1 of the wiring 28 in an instrument.
Thereby, in the lighting fixture 10 of this one embodiment, the bent end edge portion 31 of the middle reflecting plate 14 in contact with the top portion of the protrusion 35 can be disposed in a non-contact manner on the in-device wiring 28.

  In addition, the instrument main body 11, the fluorescent lamp 12, the louver 13, the temporary hanging strap 15 and the like used in one embodiment are not limited to those illustrated, and can be appropriately changed.
