The lamp 22c is connected to supply power.

  Thereby, the downlight type illuminating device with lifting device 20 is embedded in the ceiling mounting hole 30a so that the reflecting mirror 22a and the lamp 22c face downward and illuminate the floor surface.

  Next, the construction procedure for installing the downlight type illumination device with a lifting device configured as described above on the ceiling will be described with reference to FIGS.

  As shown in FIG. 3, suspension bolts 14 and 14 are previously installed on a slab behind the ceiling with a predetermined distance and suspended.

  Further, a circular ceiling mounting hole 30 a for embedding and installing the lighting device 20 in the ceiling 30 is formed.

  The diameter of the ceiling mounting hole 30a is set so that the L-shaped portion of the lower frame 21b of the instrument body 21 matches the cut end.

  When this type of downlight illumination device is installed in the ceiling 30, many of the downlight illumination devices are installed with their positions shifted from the suspension bolts 14, 14 and the ceiling mounting hole 30 a, and the core wire a of the bolts 14, 14 and the ceiling mounting hole are installed. The construction procedure will be described below by taking as an example a case where the core wire b of 30a is displaced by c in the horizontal direction.

  First, as shown in FIG. 3, the fixture body 21 and the lighting device misalignment adjusting tool 10 are prepared on the floor surface 40, and the connecting bolt 13 of the first support plate 11 of the misalignment adjusting tool 10 is attached to the second floor plate 40. The nut 13a is inserted from below into the elongated hole 12c of the support plate 12, and the misalignment adjusting tool 10 is assembled.

  Further, the support bolts 12 a and 12 a of the assembled misalignment adjusting tool 10 are inserted into the support holes 21 d and 21 d of the top plate 21 a, and the nuts 12 b and 12 b are screwed from below, and the misalignment adjusting tool 10 is placed on the upper part of the instrument body 21.

  Next, as shown in FIG. 7, the wire ropes 23 b and 23 b of the lifting device 23 are wound up, and the entire lighting fixture 22 is lifted together with the lifting and lowering portion 23 a, so that the lighting fixture 22 forms a cylindrical frame. Store in.

  At this time, since the instrument body 21 is not deformed as described above, the instrument body 21 is smoothly accommodated in the instrument body 21, and as shown in FIG. There is no case where the mirror 22a or the like is fitted and cannot be moved up and down.

  As a result, the socket portion 22b of the lighting fixture 22 is connected to the power line previously wired to the lifting device 23, and power is supplied to the lamp 22c. The lighting device 20 moves the reflecting mirror 22a and the lamp 22c downward. The construction work is completed by illuminating the lower floor.

  In the downlight type lighting device installed as described above, when the lamp is exchanged or the lighting fixture is repaired or inspected, the “descent” button of the raising / lowering switch installed on the wall or the like is pushed, and the lifting device 23 Is driven to unwind the wire ropes 23b, 23b, the unwinding lighting fixture 22 is lowered to the floor surface 40, and the lamp is exchanged.

  At the time of lowering, as shown in FIG. 11B of Patent Document 1, the reflecting mirror 22a and the like of the lighting fixture 22 are not fitted into the fixture body 21 and cannot be moved up and down, so that the reflecting mirror 22a and the like are placed on the lower frame 21b. It can be lowered smoothly without being involved.

  When the lamp replacement or the like is completed, the “up” button of the lifting switch may be pressed to wind up the wire ropes 23b, 23b of the lifting device 23 and store the lighting fixture 22 in the fixture body 21.

  In this embodiment, the illuminating device misalignment adjusting tool 10 has the connecting bolt 13 provided in the first support plate 11 and the long hole 12c formed in the second support plate 12, but the long hole is the first support.

  The first and second support plates 11 and 12 are composed of two strip-shaped plates. However, as shown in FIG. 9, a long hole 12c is formed in the top plate 21a of the instrument body 21, and the top plate The plate 21a may be configured to also serve as the second support plate 12, and the structure of the misalignment adjusting tool 10 may be simplified to reduce the number of parts. In this case, the lifting device 23 may be attached to the lower surface of the top plate 21a.

  Further, instead of the long holes, a plurality of round holes are arranged in a straight line, and the plurality of round holes are sequentially selected one by one to move the connecting position of the connecting member 13 in the horizontal direction. The deviation may be adjusted.

  In the construction procedure, the misalignment adjusting tool 10 is installed on the ceiling 30 in a state of being incorporated in the lighting device 20, but when there is no misalignment between the suspension bolts 14 and 14 and the ceiling mounting hole 30a, the misalignment adjustment is performed. You may construct without using the tool 10.

  That is, as shown in FIG. 10, the suspension bolts 14 and 14 are directly inserted into the support holes 21d and 21d formed in the top plate 21a of the instrument body 21, and the nuts 11b and 11b are screwed and supported. The misalignment adjusting tool 10 may be used only when a misalignment has occurred.

  In the case of construction without using the misalignment adjusting tool 10, the instrument body 21 needs to be installed in the ceiling mounting hole 30a while being aligned with the suspension bolts 14 and 14.

  The instrument body 21 is formed in a cylindrical frame body by a top plate 21a, a lower frame 21b, and a column 21c. However, as shown in FIG. 11, a circular ring-shaped support is provided at a substantially middle portion between the top plate 21a and the lower frame 21b. A plate 21e may be provided, and this support plate may also be configured by forming support holes 21f and 21f that pass therethrough at positions corresponding to the support holes 21d and 21d formed in the top plate 21a.

 As a result, the support plate 21e is added to the intermediate portion, and the instrument main body 21 forming the cylindrical frame is reinforced and becomes sturdy and difficult to deform.

 Furthermore, the suspension bolts 14 and 14 can be vertically supported and fixed to the two support holes 21d and 21f of the top plate 21a and the support plate 21e, and the instrument main body 21 is reinforced to be strong. Becomes more difficult to deform.

 Also, since the support holes 21d and 21f are passed through the two supporting holes 21d and 21f, the instrument body 21 cannot be deformed to fit the suspension bolts 14 and 14 even if misalignment occurs. The suspension bolt cannot be passed through the two support holes 21d and 21f, and it is possible to prevent unreasonable construction.

 Moreover, as this kind of downlight type lighting device, the number of built-in inverters increases, the socket portion 22e becomes longer, and the lighting device 20 as a whole becomes thinner and longer and requires strength. If the structure which reinforces the instrument main body 21 by providing the support plate 22e in the intermediate portion described above, the strength can be increased.

 This configuration is not limited to passing the suspension bolts 14 and 14 directly through the support holes 21d and 21f, but is also adopted in the lighting device 20 shown in FIG. You may comprise so that the support bolts 12a and 12a of the adjustment tool 10 may pass through two places, the support hole 21d of the top plate 21a, and the support hole of the newly provided intermediate support plate.

  In the present embodiment, the misalignment adjusting tool is applied to the downlight illumination device with the lifting device, but may be applied to a normal downlight illumination device having no lifting device.

  In a downlight type lighting device that does not have a lifting device, the lighting device is lifted manually and stored in a device main body installed on the ceiling.

  Also in this case, if the instrument body is forcibly installed due to misalignment, the instrument body will be deformed in the same manner as described above, and if the lighting equipment is manually pushed into the deformed instrument body and installed, the reflector will be distorted. There is a risk that the lighting performance will deteriorate or, in extreme cases, the socket part will be deformed, making it impossible to attach and detach the lamp. However, the misalignment adjusting tool of the present invention can solve these problems. .

  Although the first and second support plates 11 and 12 of the misalignment adjusting tool are made of metal, they may be made of a strong synthetic resin. Similarly, a top plate 21a, a lower frame 21b, and a column that constitute the instrument body 21 21c and 21c may also be made of a strong synthetic resin.

  According to the present embodiment, when the core wire a of the suspension bolts 14 and 14 and the core wire b of the ceiling mounting hole 30a are displaced in the linear direction, the connecting bolt 13 of the first support plate 11 is connected to the second support plate 12. The center misalignment in the linear direction can be adjusted by a simple operation of moving in the horizontal direction within the long hole 12c.

  Even when the core wire a of the bolts 14 and 14 and the core wire b of the ceiling mounting hole 30a are displaced at a certain angle in the rotation direction, the connecting bolt 13 of the first support plate 11 is connected to the second support plate 12. The center misalignment in the rotational direction can be adjusted by a simple operation by simply rotating the elongated hole 12c by the angle shifted.

  Furthermore, even when the core wire a of the suspension bolts 14 and 14 and the core wire b of the ceiling mounting hole 30a are displaced at a certain angle in the rotation direction, and further displaced in the linear direction, the connection bolt 13 of the first support plate 11 is removed. The rotation and the linear misalignment can be adjusted simultaneously by a simple operation of rotating in the elongated hole 12c of the second support plate 12 by a shifted angle and further moving in the horizontal direction.

  Thereby, the instrument main body 21 is not forcibly supported and fixed to the suspension bolts 14 and 14 which are located out of core, and the instrument main body 21 is not deformed.

  For this reason, when performing lamp replacement, repair or inspection of the luminaire, the reflecting mirror 22a of the luminaire 22 can be lowered smoothly without being engaged with the lower frame 21b.

  In addition, no gap is formed between the lower frame 21b serving as a decorative frame of the appliance body and the ceiling surface, so that the appearance of the downlight illumination device does not deteriorate.

  Furthermore, the height in the vertical direction can be adjusted by the screwing condition of the nut 13a of the connecting bolt 13, and a more convenient misalignment adjusting tool can be provided.

  Furthermore, the height can be adjusted by adjusting the screwing conditions of the suspension bolts 14 and 14 and the nuts 11b and 11b, and further by adjusting the screwing conditions of the support bolts 12a and 12a and the nuts 12b and 12b.

  The misalignment adjusting tool 10 can be applied to the downlight type illumination device 20 that does not have the lifting device 23, and has an advantage that it is more convenient.

  In construction, the misalignment adjusting tool 10 can be used only when misalignment has occurred, and a misalignment adjusting tool that is convenient in construction can be provided.

  FIG. 12 is a perspective view showing a second embodiment of a downlight type lighting device with an aligner for lighting device and a lifting device according to the present invention. The same reference numerals are given to the same parts as those in the first embodiment. It is.

  The misalignment adjusting tool 10 for a lighting device according to the present embodiment is configured by integrating the first and second support plates 11 and 12 constituting the first and second support members of the present invention. 14 and 14 and a center misalignment adjusting tool used when construction is performed with a large misalignment formed in the ceiling mounting hole 30a.

 That is, the first support plate 11 and the second support plate 12 are integrally formed of a single metal plate.

 The first support plate 11 is formed with a substantially circular through hole 11c for attaching one suspension bolt 14 and a long hole 11d penetrating in a substantially arcuate shape on the locus of a circle centered on the through hole. . The long hole is a hole for attaching the other suspension bolt 14.

 The second support plate 12 is formed with a plurality of eight support holes 12d penetrating the support holes for the lighting device of the present invention.

 The interval between the plurality of support holes 12d is formed to be approximately equal to the interval between the support bolts 12a and 12a attached to the instrument body 21, and the support bolts 12a and 12a can be supported by shifting the support holes 12d one by one. In other words, a plurality of support holes 12d are selected by the pitch of the support bolts, and the positions of the support bolts, that is, the positions of the lighting devices 20 supported by the support bolts can be changed in the horizontal direction. They are arranged in a straight line.

 A construction procedure using the illumination device misalignment adjusting tool 10 of the present embodiment configured as described above will be described.

 The misalignment adjusting tool 10 of the present embodiment is used when the core wire a of the suspension bolts 14 and 14 and the core wire b of the ceiling mounting hole 30a are significantly displaced by the dimension d as shown in FIG.

The through hole 11c of the first support plate 11 is inserted into the suspension bolt 14 (left side in the figure), the long hole 11d is inserted into the other suspension bolt 14 (right side in the figure), and the nut 11b, 11b is screwed and the center misalignment adjusting tool 10 is supported by the suspension bolts 14 and 14 in a suspended state.

  Next, two support bolts 12a and 12a are prepared, and the distance between the support holes 12d formed in the second support plate 12 and the support holes 22d and 22d formed in the top plate 21a of the instrument main body. Select a support hole that matches.

 In the case of the present embodiment, the third hole and the seventh hole from the right in the figure are selected to match.

 Next, the two support bolts 12a and 12a are passed from the support hole 12d of the second support plate 12 to the support hole 22d of the top plate 22a, and the nuts 12e and 12e and the nuts 12b and 12b are screwed from above and below to provide the second support. The instrument body 21 is supported and fixed in a state where it is suspended from the plate 12.

  At this time, when the core wire a of the suspension bolts 14 and 14 and the core wire b of the ceiling mounting hole 30a are displaced at a certain angle in the rotation direction, the range is within the range of the arc-shaped long hole 11d of the first support plate 11. Thus, the other suspension bolt 14 is moved by turning by the angle shifted from the through hole 11 as the center point, and the misalignment in the rotational direction is adjusted.

  As described above, the misalignment in the linear direction is such that the plurality of support holes 12d are arranged at the interval pitch of the support bolts 12a and 12a so that the positions of the illumination devices 20 installed in the ceiling mounting holes 30a and the support holes 12d and 12d are aligned. Adjust by selecting.

  Further, when the core wire a of the suspension bolts 14 and 14 and the core wire b of the ceiling mounting hole 30a are displaced at an angle in the rotational direction and further displaced in the horizontal direction, the arc-shaped long hole 11d and a plurality of support holes are provided. The rotation and linear misalignment are adjusted simultaneously with an interval pitch of 12d.

  In addition, when the height of the ceiling is higher or lower than the set value, the suspension bolts 14 and 14 and the nuts 11b and 11b are screwed together, and the support bolts 12a and 12a and the nuts 12b, 12b, 12e, The screwing degree of 12e is adjusted to a predetermined height.

  As a result, as in the present embodiment, even if the suspension bolts 14 and 14 and the ceiling mounting hole 30a are significantly misaligned, the instrument main body 21 is reliably supported and fixed so that the suspension bolts 14 and 14 are displaced, The instrument body 21 forming a cylindrical frame is not deformed.

  In the present embodiment, the plurality of lighting device support holes are formed of continuous holes, that is, one long hole, and the support bolt of the lighting device is moved in the horizontal direction in the long hole, whereby the linear core is formed. The deviation may be adjusted.
