Furthermore, thin disk-shaped small LED lighting devices 14 are respectively arranged at the four corners of the ceiling surface of the LED lighting ceiling 10. In addition, the layout and installation number of the LED lighting fixtures 12 and 14 shown in FIG. 5 are examples, and the layout and installation number can be arbitrarily changed as will be described later.

  FIG. 6 shows an enlarged front view of the LED lighting ceiling 10. As shown in this figure, a plurality of mounting holes 16 each formed as a circular hole having the same inner diameter are formed at equal intervals in the vertical and horizontal directions on the ceiling 10 for LED lighting. Thereby, the grid-like design is given to the ceiling surface of the ceiling 10 for LED lighting. In addition, FIG. 5 shows the grid lines 18 in FIG. 5 and the grid lines 18 are not shown in FIG. 6, but this may be provided with the grid lines 18 as a design. This means that a design in which only the intersections are arranged in a grid shape without providing the line 18 may be adopted. Incidentally, although the grid lines 18 shown in FIG. 5 are of a type that forms a square perpendicular to each other, the grid lines may be drawn obliquely so that a rhombus is formed. That is, the “grid shape” described in claim 8 includes not only a perfect square lattice shape but also a lattice shape derived therefrom, and includes both cases where there are grid lines and cases where there are no grid lines.

  FIG. 1 is an exploded view showing the interior and peripheral structure of the LED lighting ceiling 10 described above. As shown in this figure, the LED illumination ceiling 10 is attached to the lower surface of the ceiling 20 that originally exists in the room of the building.

  Specifically, a ceiling base material 22 is disposed on the ceiling 20, and a plaster board 24 that forms a ceiling surface is stretched on the lower surface thereof. A heat insulating material 26 is spread on the upper surface side of the ceiling base material 22. The LED lighting ceiling 10 is attached to the lower surface side of the plaster board 24. That is, the LED lighting ceiling 10 can be retrofitted to the existing ceiling 20.

  FIG. 2 is a longitudinal sectional view showing a state in which the LED lighting fixture 14 is attached to the LED lighting ceiling 10. As shown in this figure, the LED lighting ceiling 10 includes a ceiling panel 28 having a predetermined thickness. The plurality of mounting holes 16 described above are formed on the ceiling surface 30 side of the ceiling panel 28. However, the mounting hole 16 does not penetrate the ceiling panel 28. That is, the attachment hole 16 is opened on the ceiling surface 30 side, and is not opened on the surface opposite to the ceiling surface 30.

  As shown in FIGS. 2 and 3, the mounting hole 16 is formed in a columnar shape, and a positive electrode 32 and a negative electrode 34 formed in a substantially arc shape on the inner peripheral surface thereof are opposed to each other in the radial direction. Are arranged. That is, the plus electrode 32 and the minus electrode 34 are arranged in the circumferential direction along the inner peripheral surface of the attachment hole 16, and are arranged so that the surfaces thereof are exposed in the attachment hole 16. A short prevention groove 36 is formed between both ends of the plus electrode 32 and both ends of the minus electrode 34. Further, the heights of the plus electrode 32 and the minus electrode 34 are set lower than the depth of the mounting hole 16. The minus electrode 34 is disposed with the end portion aligned with the opening of the mounting hole 16, and the plus electrode 32 is disposed with the end portion aligned with the bottom surface of the mounting hole 16. Therefore, the plus electrode 32 and the minus electrode 34 are arranged so as to be shifted in the axial direction of the mounting hole 16.

  A first conductor 38 extends from both ends of the plus electrode 32, and a second conductor 40 extends from both ends of the minus electrode 34. Therefore, the plus electrode 32 and the minus electrode 34 are arranged in parallel to each other when seen in a plan view and a side view. In the above configuration, the plus electrode 32, the minus electrode 34, the first conductor 38, and the second conductor 40 correspond to the “feeding means” in the present invention.

  Next, the configuration on the LED lighting fixture 14 side will be described. A columnar power receiving unit 42 is erected in the center on the upper surface side of the LED lighting device 14. The power reception unit 42 is a connection unit for supplying power to the LED lighting apparatus 14, and is set to have a radial dimension that is fitted into the mounting hole 16. In addition, the power receiving unit 42 is formed in a Z shape in a side sectional view, and includes an upper end portion 42A and a lower end portion 42B. In a state where the power reception unit 42 is fitted in the mounting hole 16, the upper end portion 42 </ b> A is in contact with the minus electrode 34, and the lower end portion 42 </ b> B is in contact with the plus electrode 32.

  Further, a plurality of fixing dowels 44 are erected on the upper surface side of the LED lighting device 14 at positions (four positions forming a cross) that are equidistant with the power receiving unit 42 interposed therebetween. The fixing dowel 44 is formed in a columnar shape, and the outer diameter thereof substantially coincides with the inner diameter of the mounting hole 16. Further, as shown in FIG. 4B, the fixing dowel 44 is slidable in the radial direction. As the slide structure, for example, a pair of guides for forming a track on the upper surface side of the LED lighting apparatus 14 is formed by cutting and raising, and the guides can be inserted into the outer peripheral surface of the base end portion of the fixing dowel 44. An annular groove is formed. And the front-end | tip of a pair of guide is inserted in the groove | channel of the dowel 44 for fixation, and it sets to the intermediate part of the longitudinal direction of a guide. Further, biasing means such as a pair of compression coil springs are attached to both ends in the longitudinal direction of the guide, and the base end portion of the fixing dowel 44 is directed from both longitudinal ends of the guide toward the intermediate portion in the longitudinal direction. Press and urge. In this way, in FIG. 6, when the fixing dowels 44 are fitted into the four mounting holes 16A positioned on the cross in FIG. 6, they may be mounted as they are, and the four mounting holes 16B positioned on the diagonal line. When attaching the fixing dowel 44 to the fixing hole 44, the fixing dowel 44 may be slid radially outward along the guide and fitted into the attachment hole 16B.

  Next, the power supply system 50 incorporating the LED lighting ceiling 10 described above will be described with reference to FIG.

  The power supply system 50 includes a power storage unit 56 including a home DC power source, a battery 52 as a storage battery, and a control unit 54. A commercial power system power source 58 and an external independent power source 60 such as a solar cell are connected to the power storage unit 56 via an AC line 62. An inverter 64 that converts direct current into alternating current is interposed on the AC line 62 that connects the external independent power supply 60 and the power storage unit 56.

  On the other hand, the above-described power storage unit 56 is connected to the LED lighting device 14 in the house 68 via the DC line 66. In addition, the 1st conductor 38 and the 2nd conductor 40 of the ceiling 10 for LED lighting mentioned above are also some DC wires 66. FIG. The power storage unit 56 is also connected to the home 68 via the AC line 70. An inverter 72 that converts direct current to alternating current is interposed on the AC line 70.

  Further, the external independent power source 60 described above is directly connected to the LED lighting apparatus 14 via the DC line 74.

  In addition, as the battery 52, for example, a storage battery such as a nickel hydride storage battery, a lead storage battery, or a nickel cadmium storage battery is applicable, but other storage batteries may be used. Further, the control unit 54 adjusts the temperature of the battery 52 so as to be optimal for power storage, and controls switching between power storage and discharge to the battery 52.

  (Action / Effect)

  Next, the operation and effect of this embodiment will be described.

  A plurality of mounting holes 16 are regularly formed in a grid in the LED lighting ceiling 10. For example, when attaching the above-described thin disk-shaped LED lighting fixture 14 to the LED lighting ceiling 10, the power receiving unit 42 is inserted into the arbitrary mounting hole 16 and at the same time, the four fixing dowels 44 are attached correspondingly. What is necessary is just to insert in the hole 16. When the dowel 44 for fixing is inserted into the mounting hole 16A (see FIG. 6) positioned on the cross as viewed from the mounting hole 16 into which the power receiving unit 42 is inserted, it may be inserted as it is. When the fixing dowel 44 is inserted into the mounting hole 16B (see FIG. 6), the fixing dowel 44 may be inserted by sliding the fixing dowel 44 radially outward.

  As described above, when the LED lighting device 14 is completely mounted in the mounting hole 16 of the ceiling 10 for LED lighting, the upper end portion 42A of the power receiving unit 42 comes into contact with the negative electrode 34 and becomes conductive. The lower end portion 42B of the portion 42 comes into contact with the plus electrode 32 and becomes conductive. Thereby, the electrical connection state with a power feeding means is ensured.

  Next, the operation of the power supply system 50 will be described. Low-cost late-night power is received from the commercial power system power supply 58 and is supplied to the power storage unit 56 via the AC line 62. In the power storage unit 56, the control unit 54 converts alternating current into direct current and stores the battery 52. The control unit 54 also controls the temperature environment of the battery 52 so that the power storage performance is satisfactorily exhibited.

  The power stored in the battery 52 covers nighttime power until daytime or midnight. That is, the electric power stored in the battery 52 is converted from direct current to alternating current by the inverter 72, and then supplied to the home 68 through the AC line 70, and the alternating current device is energized. When the LED lighting fixture 14 is turned on, power is directly supplied to the LED lighting fixture 14 from the battery 52 using the DC line 66.

  In addition, since the power supply system 50 includes the external independent power source 60 such as a solar cell, the LED lighting apparatus 14 can be directly fed using the DC line 74 from the external independent power source 60. Thus, by connecting the external independent power source 60 and the DC device such as the LED lighting apparatus 14 with the DC dedicated line, there is no loss due to conversion, and simple, compact and inexpensive illumination can be realized. Note that the electric power generated by the external independent power supply 60 is appropriately sold to an electric power company.

  Here, when there is a change in the planning of a building such as a house, or when the interior of the building is changed due to a change in the family structure or the like, the mounting position of the LED lighting device 14 is changed. The power receiving unit 42 and the fixing dowel 44 may be removed from the mounting hole 16, and the power receiving unit 42 and the fixing dowel 44 may be attached to another mounting hole 16 again. Therefore, it is possible to arbitrarily change the mounting position of the LED lighting device 14 with one touch or close to it (the lighting layout can be changed). In addition, when changing the mounting position, it is possible to mount an LED lighting apparatus having a different specification. As described above, according to the present embodiment, it is possible to produce a variety of illumination spaces over a long life cycle.

  Further, in the present embodiment, since the power supply system 50 using the battery 52 is provided, the power storage unit 56 (battery 52) and the LED lighting device 14 are connected to the DC line 74 without installing equipment such as an inverter. , 66 can be connected directly. As a result, according to the present embodiment, it is possible to introduce the LED illumination system while minimizing incidental facilities.

  Furthermore, in the power supply system 50 of the present embodiment, the battery 52 can receive and store power from both the commercial power system power supply 58 and the external independent power supply 60, so that it is possible to use cheap midnight power or power taken from the external independent power supply. Once stored in the battery 52, the power stored in the battery 52 can be used when the LED lighting apparatus 14 is used. As a result, according to this embodiment, an LED illumination system can be constructed at low cost.

  In the present embodiment, the plurality of mounting holes 16 each having the same shape, size, and depth are regularly provided in the ceiling surface 30 of the ceiling 10 for LED lighting. When doing so, it is only necessary to insert the power receiving unit 42 and the fixing dowels 44 into the plurality of mounting holes 16. As a result, according to the present embodiment, the LED lighting device 14 can be attached to the ceiling surface 30 by a one-touch operation.

  Furthermore, in this embodiment, since the plus electrode 32 and the minus electrode 34 are respectively arranged facing the inner peripheral surfaces of the plurality of mounting holes 16 with the short prevention groove 36 interposed therebetween, the power receiving unit of the LED lighting device 14 As soon as 42 is inserted into the mounting hole 16, an electrical connection state is secured. Therefore, both attachment to the ceiling surface 30 of the LED lighting fixture 14 and ensuring of an electrical connection state can be performed by one-touch operation.

  Further, in the present embodiment, the plurality of mounting holes 16 are arranged in a grid pattern on the ceiling surface 30, so that when the power receiving unit 42 and the fixing dowel 44 are inserted, they can be easily aligned with the mounting holes 16. It can be carried out. As a result, according to the present embodiment, it is possible to more easily perform the mounting operation of the LED lighting apparatus.

  Furthermore, in this embodiment, since the ceiling 10 for LED lighting is comprised as one independent panel material, several sheets can be conveyed and stored collectively. Therefore, the total cost can be reduced by increasing the transportation and storage efficiency.

  In this embodiment, the heat insulating material 26 is continuously spread on the upper surface side of the ceiling base material 22, and the LED lighting ceiling 10 configured as a panel material is provided on the lower surface side of the ceiling base material 22. Assemble the ceiling 20 of the building. That is, the mounting of the LED lighting ceiling 10 is completed on the lower surface side of the ceiling base material 22. For this reason, a discontinuous part is not formed in the heat insulating material 26 spread on the upper surface side of the ceiling base material 22. As a result, according to the present embodiment, it is possible to easily change the arrangement of the LED lighting apparatus 14 (design change of the living space), and to improve the heat insulation.

  Supplementing this effect, as shown in FIG. 8 (A), the conventional downlight 80 has a hole 84 in the ceiling 82 and is embedded using a spring 86. For this reason, the power receiving portion 88 and the wiring 90 of the downlight 80 go to the back of the ceiling 20, and it is necessary to form the wiring hole 94 in the heat insulating material 92, and a discontinuous portion is formed in the heat insulating material 26. In addition, since the gap 96 is formed around the hole in the ceiling 82, cold air and sound enter the room and heat loss is large. Furthermore, since work for drilling the ceiling 82 and work for drilling the heat insulating material 92 are required, the workability is also low. As shown in FIG. 8B, the same problem occurs even when compared with a case where the downlight 80 is accommodated by normal connection and is fixed by being hooked on the hook 98.

  On the other hand, in the case of the ceiling 10 for LED lighting according to the present embodiment, such a gap 96 is not formed, and the heat insulating material 26 is maintained in a continuous state, so that the heat insulating property is improved. Can be made. Moreover, since a drilling operation becomes unnecessary, the workability can be improved.

  According to the above configuration, the mounting position of the LED lighting apparatus 12 can be changed to an arbitrary position on the wiring duct 108 by sliding the power reception unit 132 along the wiring duct 108. Therefore, the same effect as the first embodiment described above can be obtained.

  Further, in the present embodiment, since the wiring duct 108 is disposed in the gap 106 between the adjacent building units 104, the gap 106 originally formed in the unit building 102 can be used effectively. . In other words, it is not necessary to newly provide a mounting portion on the ceiling surface 121 of the building unit 104. In addition, since the wiring duct 108 is disposed so as not to protrude from the ceiling surface 121, the design of the ceiling surface 121 is not impaired.
