That is, because the structure is such that the height of the wire stopper 13 can be freely changed, the height adjusting mechanism 21 is operated so that the lamp 9 for indirect illumination is arranged at the most suitable height position. As a result, it is possible to adjust the hanging height of the mold member 5a from the ceiling rail 3, and it is possible to easily adjust the brightness of the indirect illumination light according to the room.

Further, since the lamp 9 for indirect illumination and the lamp 25 for illuminance reinforcement are attached together to one mold member 5a, it is not necessary to separately install the lamp 25 for illuminance reinforcement on the ceiling surface 2, and it is not necessary to use the conventional structure. As described above, it is possible to save the labor of producing and constructing a work material directly attached to the wall surface or the ceiling, reduce the construction work cost and the like, and easily wire the lamp 25 for illuminance reinforcement. Further, by installing the lighting outlets 10 at a plurality of places on the ceiling surface 2, the power cord 1
Since it is possible to connect 1 to any of the outlets 10, it is not necessary to extend the power cord 11 for a long time, and along with this, the unsightly appearance due to the sagging of the power cord 11 can be eliminated at the same time. Further, in this embodiment, since the socket base 23 of the lamp 25 for illuminance reinforcement is adhered to the inner surface of the mold material 5a, the lamp 25 for illuminance reinforcement can be easily mounted in the mold material 5a, and the ceiling surface can be adjusted as in the conventional case. There is also an advantage that the construction work can be reduced as compared with the case where the downlight is installed in 2.
