JP 2002-285675 A (see FIG. 17)

  By the way, as mentioned above, it is the structure by which an illuminating device is attached to a ceiling board partially, Comprising: In a comparatively large room | chamber interior, a comparatively big illuminating device is provided over several sheets of ceiling boards. And this illuminating device may be arrange | positioned so that it may face from the opening formed over the several ceiling board. Here, a plurality of ceiling plates to which the lighting device is attached are formed with openings having specific shapes according to the shape of the lighting device. Then, the shape of the opening of the specific shape is different for each ceiling board according to the size of the room and the installation position of the lighting device. For this reason, when the opening of this specific shape is formed in advance in a ceiling plate production factory or the like, the ceiling plate production process becomes complicated. Furthermore, it is necessary to accurately describe a plurality of ceiling plates each having an opening having a specific shape according to a predetermined direction and order at the time of forming the ceiling. On the other hand, when forming openings with a specific shape on multiple ceiling plates at the work site where the ceiling is formed, the work is performed so as to match the shape of the lighting device directly, which makes the work site complicated. In addition, the work efficiency was not good.

  Generally, in a building having a plurality of relatively large indoor spaces, it is necessary to change the size and installation position of the lighting device according to the size of each indoor space. In addition, various lighting devices may be installed so that each indoor space has a different image. And according to the installation position of the illuminating device and its shape, more kinds of ceiling boards in which the openings having the above-mentioned specific shapes are formed are required. For this reason, the operation | work which each forms the opening of a specific shape in a ceiling board, the operation | work which installs the said ceiling board, etc. were further complicated. And the construction cost which installs the ceiling which has the opening of these special shapes was also going to increase. If a lighting device having a relatively standard shape is used, it is possible to suppress the complexity of the molding work and installation work of a plurality of ceiling plates for installing the lighting device, but the brightness of the room is sufficient. Therefore, it is necessary to determine the installation position of the lighting device according to the size of the indoor space.

  The present invention proposes a ceiling board with a lighting device that can generate a lighting configuration according to an indoor space while suppressing the complexity of the ceiling forming work.

The present invention, in the rectangular ceiling plate forming a ceiling of the room and arrayed a plurality in a matrix, the corners of the main plate portion, with an opening, has translucency, opening provided parts, the lighting unit cover for shielding the opening from below, it comprises a lighting device comprising a light emitting source that is disposed on the light cover, by rotating converted into a horizontal direction, It is a ceiling board with an illuminating device which can arrange | position and arrange | position the corner | angular part provided with the said illuminating device.

  Here, the quadrangular ceiling plate can have various shapes such as a square, a rectangle, a parallelogram, a rhombus, and a trapezoid. In addition, when the ceiling board is rotated and converted in the horizontal direction, a square shape with the least restriction for changing the position of each corner can be suitably used. In addition, the corner provided with the lighting device has a configuration that is one corner of the main plate portion of the ceiling panel, a configuration that is two corners, a configuration that is three corners, and a configuration that is all four corners. Either can be used.

  In the ceiling panel with a lighting device having such a configuration, various illumination forms can be generated on the ceiling according to the installation position and the position of the corner portion including the lighting device in the ceiling panel. Here, since the present invention is configured to arrange the lighting device at the corner, the ceiling plate can be rotated and converted in the horizontal direction to change the illumination position within the same plate, Various illumination forms can be generated relatively easily. Furthermore, various lighting forms can be generated by changing the installation position of the ceiling plate with a plurality of lighting devices and the position in the corner plate where the lighting devices are arranged, respectively. Design and wide applicability can be demonstrated. Therefore, if a ceiling board with a lighting device is prepared in advance, the setting of the lighting position and the change of the lighting mode can be appropriately performed according to the size of the indoor space and the indoor image. In addition, as mentioned above, from the four types of ceiling panels with lighting devices, each of which has a corner with a lighting device as one corner, two corners, three corners, and all four corners. By preparing a plurality of types, it is possible to generate more various illumination forms on the ceiling by combining these.

  In addition, the ceiling plate with a lighting device has a structure in which an opening is provided at a corner of the main plate portion and the lighting device is disposed so as to shield the opening. Thus, it can be produced relatively easily by providing the step of forming the opening and the step of attaching the lighting device. Furthermore, as described above, if one or more types of ceiling boards with lighting devices are prepared in advance, various lighting forms can be generated, so that a relatively large amount can be produced. Therefore, this ceiling panel with a lighting device is excellent in productivity and can sufficiently suppress the production cost. In addition, various things, such as a fluorescent lamp, an incandescent lamp, and light emitting diode LED, can be used as a light emission source of this illuminating device.

  In addition, the ceiling plate with a lighting device having such a configuration can be formed in the same shape as a normal quadrangular ceiling plate, so that it can be installed in the same manner as a normal ceiling plate, and the installation work is easy and easy. It can be done efficiently. Since the productivity and workability are thus improved, this construction cost can also be reduced.

  Since the ceiling panel with a lighting device includes a lighting device in which a light source is disposed above a translucent lighting cover, various lighting forms can be generated by changing the shape of the lighting cover. It is also possible to do. As this shape, for example, various shapes such as a triangular shape, a quadrangular shape, and a fan shape can be used. In addition, the emission color can be changed by setting the illumination cover to a clear color. As described above, the present invention has excellent applicability such that the indoor lighting form can be changed by a configuration improvement that can be carried out relatively easily such as changing the shape of the lighting cover or changing the cover color. It is.

  The above-described ceiling panel with a lighting device, in which a corner portion provided with the lighting device is arranged so as to be adjacent to each other, thereby generating a combined lighting form in which a plurality of lighting devices are combined with each other on the ceiling Is proposed.

  In such a configuration, the lighting device provided on the ceiling plate with the lighting device is limited in its size and light emission output, but a plurality of the ceiling plates are arranged so that a plurality of lighting devices are adjacent to each other. Therefore, the brightness can be increased. In this way, by providing a composite lighting form in which a plurality of lighting devices are combined at a predetermined position on the ceiling or at a plurality of locations, sufficient brightness can be easily ensured according to the size of the indoor space. It can be done. Further, as this combined illumination mode, different illumination modes can be generated relatively easily by changing the number of lighting devices to be combined or changing the adjacent positions.

  Here, in the combined illumination form, the form change caused by changing the shape of the opening is larger than that in the single illumination apparatus. Therefore, the indoor image can be easily changed according to the installation position and the number of installation of the ceiling boards with lighting devices.

  On the other hand, in the ceiling board with an illumination device described above, the illumination device is disposed at one corner of the main plate portion, and the form of the illumination cover is configured to indicate the outside of the corner portion. A configuration is proposed that is used as a guidance display by positioning a corner provided with a device in a specific direction. Here, as a form indicating the outside, a form such as a triangle, an arrow, a bowl, a wedge, or the like can be used.

  In such a configuration, the lighting device configured to point to the lighting cover can be used as a so-called guide lamp that guides in the pointing direction. Generally, the ceiling can be visually recognized relatively easily even in a relatively large room or a room in which various appliances are arranged. Therefore, the guidance display provided on the ceiling in this way can exhibit an excellent guidance action. For example, by arranging a ceiling panel with a lighting device so that the point indicated by the lighting device is an emergency exit, the lighting device is caused to emit light in the event of a disaster, etc. It can be confirmed. In addition, it is preferable that the lighting device used as the guidance display is clearly distinguished by changing the emission color from other lighting devices so that the guidance action can be further enhanced.

  Here, the ceiling plate with lighting device can be emphasized in the direction indicated by arranging a plurality of lighting panels so that the lighting device is continuous in a specific direction. The effect can be further enhanced.

  In addition, in this structure, it is also possible to install the ceiling board with an illuminating device used as normal illumination and the ceiling board with an illuminating device used as the above-described guidance display. Moreover, both these illuminating devices can also be set as the structure provided in the different corner | angular part of a single ceiling board.

  Another aspect of the present invention is a lighting device provided on a quadrangular ceiling board that forms a room ceiling by arranging a plurality of sheets vertically and horizontally, and is formed at a corner of a main plate portion of the ceiling board. The illumination device includes a translucent illumination cover disposed so as to shield the opening from below and a light emission source disposed on the illumination cover.

  The ceiling plate with a lighting device of the present invention includes an opening at the corner of the main plate portion of the quadrangular ceiling plate, has translucency, and is fixed to the main plate portion so as to shield the opening from below. A lighting device including a lighting cover and a light emitting source disposed on the lighting cover, the corner portion including the lighting device can be position-converted by rotating in a horizontal direction. Since it is the structure which carried out, various illumination forms can be produced | generated by changing the installation position or changing the rotation position of the corner | angular part in which the illuminating device was provided. Moreover, since this ceiling board with an illuminating device can be made into the substantially same square shape as a normal ceiling board, the installation work of a ceiling board can be performed easily. And an installation position can also be set and changed suitably according to the width of indoor space, and the appropriate illumination form excellent in the design property can be produced | generated easily. Furthermore, the ceiling plate with lighting device can be produced in a variety of lighting forms by installing one or more in various indoor spaces, so that a relatively large quantity can be produced and the productivity is improved. . Thus, the ceiling board with a lighting device of the present invention has excellent installation workability and productivity, and can reduce the construction cost for forming the ceiling.

  Here, in the configuration in which the corner portion provided with the lighting device is arranged so as to be adjacent to each other to generate a composite lighting form in which the plurality of lighting devices are combined with each other on the ceiling, the plurality of lighting devices Brightness can be increased by adjoining the device, and sufficient brightness can be ensured indoors by setting the generation position and number of generations of this composite illumination form according to the size of the indoor space. . Moreover, various composite illumination forms can be generated depending on how the lighting devices are combined.

  On the other hand, the lighting device is disposed at one corner of the main plate portion, and the lighting cover is configured to point to the outside of the corner, and the corner provided with the lighting device is in a specific direction. In the configuration that is used as the guidance display by being positioned, an excellent guidance action can be exhibited by providing the guidance display on the ceiling that can be visually recognized by a person in the room relatively easily.

Embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a plan view showing a state in which a composite lighting form A is generated on a ceiling by adjoining four ceiling boards 1 with an illumination device according to the present invention, and FIGS. 2 and 3 are attached with the illumination device. It is an enlarged view showing the corner | angular part 5a provided with the illuminating device 10 of the ceiling board 1. FIG. Here, the ceiling plate 1 with the lighting device includes a main plate portion 2 having a substantially square shape, and standing edges 3 that rise upward from the four sides of the main plate portion 2. The standing edge 3 is formed with a support side edge 4 that is bent outward from the upper end edge. The support side edge 4 is supported on the support portion g of the ceiling plate suspension rod f assembled in a lattice shape, whereby the ceiling plate 1 with the illumination device is disposed (see FIG. 19). Here, the lower surface of the main plate portion 2 constitutes the ceiling surface when the ceiling plate 1 with the lighting device is disposed.

  In addition to the ceiling plate 1 with the lighting device, a normal ceiling plate 9 having a main plate portion, a rising edge, a supporting side edge, and the like is also supported on the ceiling plate support rod f as described above. It is arranged (see FIG. 19). This normal ceiling board 9 is not provided with the illuminating device 10 mentioned later.

  In the main plate portion 2 of the ceiling plate 1 with the illumination device, a triangular opening 6 having a vertex in the corner end direction is formed in one corner portion 5a. An opening edge 7 that rises upward is formed in the opening 6, and the lighting device 10 is fitted and attached to the opening edge 7.

  The illumination device 10 includes an illumination cover 13 that shields the opening 6 provided in the corner 5a of the main plate portion 2 from below, and a plurality of light emitting diodes (hereinafter referred to as LEDs) 12 installed on the illumination cover 13. It is composed of Here, the illumination cover 13 is inserted into the air space surrounded by the opening edge 7 of the opening 6 and shielded from the opening 6 and a dish-shaped cover main body 13a and an outer periphery of the cover main body 13a. And a cover support portion 13b supported on the upper surface of the main plate portion 2 so that the lower surface of the cover main body portion 13a is substantially flush with the lower surface of the main plate portion 2 in the fitted state. ing. The cover main body 13a has a dish-like shape composed of a triangular bottom fitted to the opening 6 and a side edge rising upward from the three sides, and the side edge is fitted to the opening edge 7. As a result, the fitting is performed so as to shield the opening 6. In the fitted state, the cover main body 13 a is joined and fixed to the opening edge 7 of the opening 6. Moreover, this illumination cover 13 is formed from the translucent material which permeate | transmits light emission of LED12. In this embodiment, the illumination cover 13 is formed from an acrylic resin material.

  On the above-described illumination cover 13, a base support 14 for supporting the triangular substrate 11 provided with a plurality of LEDs 12 is disposed. The substrate support 14 includes a dish-like support main body 14a that fixes the substrate 11, and a fixed edge 14b that extends outward from the periphery of the support main body 14a. Here, the support main body portion 14a has a dish shape including a triangular upper portion and a side edge standing downward from three sides of the upper portion, and the substrate 11 is fixed to a region surrounded by the side edge. Is done. Then, in the state where the substrate 11 is fixed, the base support 14 places the fixed edge 14b on the cover support portion 13b of the illumination cover 13, and joins the fixed edge 14b and the cover support portion 13b. To do. Thereby, the board | substrate 11 with which LED12 was arrange | positioned is enclosed by the illumination cover 13 and the board | substrate support body 14. As shown in FIG. The support main body 14 a of the substrate support 14 has a triangular shape that is substantially the same as the cover main body 13 a of the illumination cover 13.

  In the illumination device 10, a plurality of LEDs 12 are arranged on a substantially equal surface on a triangular substrate 11. All the LEDs 12 are connected to a predetermined power supply device via a switch device (not shown) (not shown). When all the LEDs 12 emit light, the lighting device 10 has a substantially triangular shape of the lighting cover 13. It comes to light up. The LED 12 is a light emission source according to the present invention.

  In the present embodiment, the above-described illumination cover 13 is joined to the opening edge 7 of the main plate portion 2 by a predetermined screw, and the substrate support 14 is joined to the illumination cover 13 by a predetermined screw. . Further, the substrate 11 is joined to the substrate support 14 by a predetermined screw. In this way, since they are respectively fixed by joining with screws, inspection or repair can be easily performed by releasing them.

  Here, in the ceiling board 1 with the lighting device of the present embodiment, the lighting device 10 is provided at one corner 5a, and the lighting device 10 is provided at the other three corners 5. Not provided.

  In this way, the lighting device 10 is installed in such a manner that four ceiling boards 1 with the lighting device in which the lighting device 10 is arranged at the corner 5a are adjacent to each other as shown in FIG. This is formed by installing the four ceiling boards with lighting devices 1 by rotating and converting them in the horizontal direction so that the respective corners 5a are positioned in four different directions. Thereby, the composite illumination form A in which the four triangular illumination devices 10 are combined is generated. And by installing four ceiling boards 1 with an illuminating device as a set in this way at predetermined intervals, it is possible to form a ceiling in which the composite illumination forms A are aligned as shown in FIG.

  Here, the composite lighting form A composed of the four ceiling panels with lighting devices 1 exists as a single piece of lighting in which the four lighting devices 10 are integrated, and therefore can be relatively bright lighting. Then, by appropriately setting the position and the number of installation of the four ceiling boards with lighting devices 1 according to the size of the indoor space, sufficient brightness can be secured in the indoor space.

  In addition, since the ceiling board 1 with an illuminating device has the same basic shape as the normal ceiling board 9 as described above, it can be easily installed even when the installation position and the number of installations are different. In addition, the ceiling forming operation can be performed by installing the ceiling plate 1 with the lighting device and the normal ceiling plate 9, so that the workability is excellent and the working efficiency is improved. For example, in the case of forming a ceiling in which the size of the indoor space is different, if the ceiling plate 1 with the lighting device and the normal ceiling plate 9 are prepared, the installation position and installation of the ceiling plate 1 with the lighting device are provided. By appropriately setting the number, it is possible to provide an indoor space with appropriate brightness.

  On the other hand, two ceiling plates 1 with an illumination device described above are installed so that the corners 5a and 5a provided with the illumination device 10 face each other, and normal ceiling plates 9 are installed on both sides thereof. As shown in FIG. 5, a composite illumination form B different from the composite illumination form A described above can be generated. Here, the two ceiling boards 1 with an illuminating device are installed by rotating and converting in the horizontal direction so that the corner portions 5a are opposite to each other in the diagonal direction. In addition, although the composite illumination form B which consists of the ceiling board 1 with two illumination apparatuses becomes weak compared with the above-mentioned composite illumination form A, it is sufficient for indoor space by increasing the number of installation. It is possible to ensure brightness.

  Thus, various composite illumination forms can be generated by changing the positional relationship between the ceiling panels 1 with a plurality of lighting devices. And even if it exists in the ceiling board 1 with the same illuminating device, an indoor image can also be changed by changing a composite illumination form in this way. Moreover, it is also possible to change the illumination image of the whole room by disposing the ceiling boards 1 with the lighting devices so that the above-described combined lighting form A and the combined lighting form B are arranged side by side. Therefore, if the ceiling board 1 with the lighting device and the normal ceiling board 9 are prepared, it is possible to ensure appropriate brightness as described above and to provide different indoor images.

  Furthermore, in such a ceiling board 1 with an illuminating device, as described above, the illuminating device 10 including the triangular illuminating cover 13 having a vertex at the corner end of the corner portion 5a is disposed. The lighting cover 13 is also in a form in which the outside of the corner portion 5 is pointed by the vertex. The ceiling plate 1 with the lighting device is installed such that the corner portion 5a is positioned in a specific direction. Similarly, as shown in FIG. 6, a plurality of ceiling boards with lighting devices 1 are installed such that each corner 5a is in a straight line. Thereby, it can be made to function as what is called a guide light to this specific direction by lighting the illuminating device 10 of the ceiling board 1 with each illuminating device. For example, the ceiling board 1 with the lighting device is installed so that the corner 5a where the lighting device 10 is disposed is positioned in a specific direction where the emergency exit exists. And when a disaster etc. generate | occur | produce, it becomes the guidance display which guides to an emergency exit to the person who exists indoors by lighting this illuminating device 10. FIG. Here, the illuminating device 10 has a light emission color (for example, green) different from that of other illuminating devices, and is easily recognized as a guidance display.

  Here, in a relatively large indoor space or an indoor space where various devices are placed, it may be difficult for a person in the room to find the position of the emergency exit. For this reason, by installing a guidance display on the ceiling that is most easily overlooked by a person in the room, the emergency exit is reached according to this guidance display. Therefore, this guidance display can be easily recognized by a person in the room and can be guided accurately, and the guidance action can be sufficiently exhibited.

  In addition, when installing the ceiling board 1 with an illuminating device as the guidance display in this way, an illuminating device as a main illumination is separately installed. For example, two types of ceiling boards 1 with lighting devices of different emission colors are prepared, one of which is arranged so as to generate the above-described combined lighting forms A and B, and the other is arranged so as to be used as a guidance display. You can also.

  As described above, the ceiling plate 1 with the lighting device has a configuration in which the lighting device 10 is disposed at the corner portion 5a of the main plate portion 2, so that the corner portion 5 is converted in position by rotating in the horizontal direction. Thus, when the ceiling is formed, various illumination forms can be generated. Moreover, since this ceiling board 1 with an illuminating device is substantially the same square shape as the normal ceiling board 9, since it can be installed in arbitrary positions, an installation position is decided at any time according to the width of indoor space. It is possible. Accordingly, by preparing the normal ceiling plate 9 and the ceiling plate 1 with the illumination device at the work site where the ceiling is formed, various illumination forms corresponding to the size of the indoor space and the indoor image are generated. It becomes possible. And the complication of this work site can be eased and work efficiency increases. Furthermore, since the ceiling board 1 with the lighting device can be used for ceilings of various indoor spaces, it is possible to produce a relatively large amount, and it is suitable for molding at a ceiling board production factory. Yes. Thus, the overall construction cost can be reduced by improving the work efficiency and productivity.

  Moreover, although the ceiling board 1 with an illuminating device mentioned above is the structure which has arrange | positioned the illuminating device 10 to the square-shaped corner | angular part 5a, as FIG. It is also possible to use the ceiling plate 21 with the lighting device having a configuration in which the lighting devices 10 and 10 are respectively disposed at the corners 5a and 5a. Thereby, for example, a plurality of composite illumination forms A can be generated along the diagonal direction of the ceiling board 1. Similarly, it is also possible to adopt a configuration in which the illumination device 10 is disposed at each of the three corners 5a or a configuration in which each of the corners 5a is disposed (not shown). Further, by preparing each of the arrangements with one to four such lighting devices 10, it is possible to generate various composite lighting modes, and according to the size of the indoor space and the indoor image. The illumination form can be generated relatively easily.

  Moreover, although the illuminating device 10 of the ceiling board 1 with an illuminating device mentioned above is the structure which used LED12 as the light emission source, as this other structure, as shown in FIG. It can also be arranged as a source. Even in such a configuration, the lighting device 10 ′ shines in a triangular shape when the fluorescent lamp 19 emits light, and thus the same operational effects as those of the LED 12 described above can be exhibited. Here, in addition to the LED 12 and the fluorescent lamp 22, an incandescent lamp or the like can be used as the light source. In FIG. 8, the illumination device 10 ′ has the same configuration except that the LED 12 of the illumination device 10 described above is changed to a fluorescent lamp 19, and the same components are denoted by the same reference numerals and details thereof are omitted.

  On the other hand, in addition to the triangular illumination device 10 as described above, a fan-shaped illumination device 30 may be arranged at the corner 5a of the main plate portion 2 as shown in FIG. In the same manner as described above, the ceiling plate 31 with the lighting device is disposed in such a manner that the corner portions 5a on which the fan-shaped lighting devices 30 are disposed are adjacent to each other, thereby generating the composite lighting form C. Can be. Further, as shown in FIG. 10, it is also possible to adopt a configuration in which a strip-shaped illuminating device 40 that connects both side edges of the corner portion 5 a is disposed on the corner portion 5 a of the main plate portion 2. It is also possible to generate the composite illumination form D by arranging four ceiling boards 41 with the illumination device in the same manner. Similarly, as shown in FIG. 11, four ceiling plates 51 with illumination devices in which arcuate illumination devices 50 that connect both side edges of the corners 5 of the main plate portion 2 are arranged in the same manner to form a composite. It may also be possible to generate the illumination form E. Each of these composite illumination forms A, C to E has different illumination forms as shown in FIGS. 1 and 9 to 11.

  Furthermore, as shown in FIG. 12, a ceiling plate 61 with a lighting device in which a line-shaped lighting device 60 extending in the diagonal direction of the main plate portion 2 is disposed at the corner portion 5 a of the main plate portion 2 may be used. Similarly to the above, it is also possible to form the composite illumination form F by arranging four pieces so that the lighting devices 60 are adjacent to each other. Moreover, since this illuminating device 60 becomes the shape which tapered in the corner end direction, it also has a form which points outside. Therefore, it is also possible to use the ceiling plate 61 with the lighting device as a guidance display by arranging one or a plurality of the ceiling plates 61 with the corner portions 5a positioned in a specific direction.

  In addition, even if it exists in the ceiling boards 31, 41, 51, 61 with an illuminating device mentioned above, another compound illumination form (illustration omitted) is carried out by combining 2 sheets or 3 sheets, respectively, similarly to the ceiling board 1 with an illuminating apparatus. It is also possible to generate a ceiling having various illumination forms. In addition, the lighting device 30, 40, 50, 60 is arranged at the two corners 5a, the three corners 5a, and all the corners 5a. It is also possible to generate a form.

  On the other hand, in the ceiling board 1 with the lighting device of the above-described embodiment, the lighting device 10 is arranged at a predetermined distance from both side edges of the corner portion 5a of the main plate portion 2 (see FIG. 1). ). This is because it is difficult to form the opening 6 along the corner edge of the corner 5a. Therefore, as shown in FIGS. 13 and 14, the illumination device 70 is configured such that the illumination cover 73 has a shape along both side edges of the corner portion 5 a of the main plate portion 2.

  As shown in FIG. 14 (a), the illumination cover 73 has two sides along both side edges of the corner 5a when attached to the main plate 2, and covers the opening 6 from below. As shown in FIG. 14 (b), the main body 73a includes a fitting wall portion 73b that stands up from the upper surface of the shielding portion 73a and is fitted into the opening 6 from below. Here, the shielding part 73a of the illumination cover 73 has a shape in which the central area is substantially horizontal and the peripheral area is inclined upward. The peripheral area having such an inclined shape diffuses light emitted from the illumination cover 73 so that light is irradiated from the entire area of the shielding portion 73a of the illumination cover 73. The lighting cover 73 has a main wall portion 2 by inserting a fitting wall portion 73b into the opening portion 6 from below the opening portion 6 and joining the fitting wall portion 73b and the opening edge 7 with a predetermined screw. Fixed to. In addition, this insertion wall part 73b is formed so that it may become higher than the opening edge 7. FIG. In addition, in the illumination cover 73 that covers the opening 6 from below, a plate-like substrate support 74 provided with the substrate 11 on which the LEDs 12 are disposed covers the opening edge 7 from above so that the main plate portion 2 is covered. Installed on top and joined. Here, the board | substrate support body 74 is comprised from the support plate part 74a which fixes the board | substrate 11, and the support wall part 74b extended below from the periphery of this support plate part 74a. The support plate portion 74 a has a substantially triangular shape that covers the opening edge 7 of the opening 6. The lower end of the support wall portion 74 b is formed so as to contact the upper surface of the main plate portion 2 when the bottom surface of the support plate portion 74 a is placed on the upper end of the fitting wall portion 73 b of the lighting cover 73. The support wall 74b is provided with a notch (not shown) so that the screw that joins the illumination cover 73 and the opening edge 7 does not contact. Further, at the upper end of the insertion wall portion 73b of the illumination cover 73, screw portions having predetermined screw holes are projected inwardly at four locations (not shown) and placed on the upper end of the insertion wall portion 73b. The substrate support 74 and the illumination cover 73 are joined by a predetermined screw.

  As shown in FIG. 13, four ceiling plates 71 with lighting devices having such lighting devices 70 provided at the corners 5a are arranged so that the corners 5a are adjacent to each other, so that the composite lighting form G can be obtained. Form. In this composite illumination form G, since the gaps between the respective illumination devices 70 are narrower than in the above-described composite illumination form A (see FIG. 1), the form is more integrated. . Further, as shown in FIG. 15, an illumination device 70 ′ is provided in which the shielding portion (not shown) of the illumination cover 73 ′ extends in a direction opposite to the corner end along both side edges of the corner portion 5 a. It can also be set as ceiling board 71 'with an illuminating device. The composite lighting form G ′ generated from the ceiling plate 71 ′ with the lighting device is a shape that is closer to a quadrangle and increases the unity of each lighting device 70 ′.

  Furthermore, in the configuration of the above-described embodiment, for example, as shown in FIG. 14 (b), the support side edge 4 of the standing edge 3 provided on the four sides of the main plate portion 2 is used as a ceiling plate suspension rod. Although it is the structure supported on the support part g of f, this invention is applicable also to the ceiling board provided with various support forms besides this. For example, as shown in FIG. 16, the ceiling plate 91 with the lighting device is erected upward after being bent inward from the four sides of the main plate portion 82, and both sides of the corner portion 5 of the erected edge 83. And a support collar 84 that protrudes outward and is bent into a collar shape and can be elastically tilted inward and outward. The ceiling plate 91 with the lighting device is returned to the support portion g after the support flange portion 84 is tilted inward by pressing the support flange portion 84 from below the ceiling plate suspension rod f. It is arranged so as to be placed.

Set up. As with the above-described lighting device 70, the lighting device 90 has a shape in which the shielding portion 93a of the lighting cover 93 is inclined upward at its periphery, and diffuses the light emission of the LEDs 12 provided on the lighting cover 93, Irradiation is possible from the entire area of the shielding part 93a. The illumination cover 93 has a fitting wall portion 93b fitted into the opening edge 7 and joined by a predetermined screw, and a substrate support 74 to which the substrate 11 on which the LEDs 12 are arranged is fixed is illuminated from above the main plate portion 82. It is fixed to the cover 93. As shown in FIG. 17, the ceiling plate 91 with the illumination device generates four composite illumination forms H on the ceiling by arranging four pieces so that the illumination devices 90 are adjacent to each other. This composite illumination form H is substantially the same as the composite illumination form G ′ in FIG. 15 described above.

  Furthermore, as shown in FIG. 18, as a ceiling plate 91 ′ with a lighting device, a standing edge 83 ′ that stands once upward from the four sides of the main plate portion 82, bends inward, and rises upward, and the standing edge 83 ′ Support corners 84 that protrude outward and bend into a hook shape and can be elastically tilted inward and outward are provided on both sides of the corner 5. Even in the ceiling plate 91 ′ with the lighting device, as a configuration including the lighting device 90 described above, by arranging the four lighting devices 90 so as to be adjacent to each other, the composite lighting mode H (see FIG. 17). ) Can be generated.

FIG. 18 is a cross-sectional view along one side edge of the corner 5a provided with the lighting device 90 of the ceiling plate 91 'with the lighting device, as in FIG.

  In the ceiling plates 91 and 91 ′ with the illumination device described above, the distance at which the main plate portion 82 bends inward from the side edge can also be changed variously. For example, when the ceiling is formed by making the distance bent inward from the side edge of the main plate portion equal to the distance approximately half of the horizontal width of the ceiling plate suspension rod f, there is a gap between the ceiling plates. Can be eliminated. In this configuration, a combined illumination form (not shown) in which four illumination devices are adjacent to each other is a substantially square-shaped integrated illumination.

  Further, in the ceiling plate configured to be arranged on the ceiling plate suspension rod f by such a support rod portion 84 (see FIG. 16), the bottom surface of the illumination cover 13 described above is flush with the bottom surface of the main plate portion. It can also be set as the ceiling board (illustration omitted) with an illuminating device which arrange | positions the illuminating device 10 (refer FIG. 3) to perform. In addition, the above-described fan-shaped illumination device 30, the strip-shaped illumination device 40, the arc-shaped illumination device 50, and the line-segment illumination device 60 constitute a ceiling plate with an illumination device (not shown). May be.

  In addition, similarly to the illumination covers 73 and 93 having the shape along the both side end surfaces of the corner portion 5a of the illumination devices 70 and 90 described above, each of the illumination devices in a fan shape, a strip shape, an arc shape, and a line segment shape (not shown) Can also be formed.

  In this invention, it is not limited to the Example mentioned above, About another structure, it can change suitably within the range of the meaning of this invention. For example, it is also possible to adopt a configuration in which a plurality of types among the above-described lighting devices 10, 30, 40, 50, 60 are arranged at the corner 5 a of the single main plate 2. In this case, it is possible to generate an appropriate composite lighting form by arranging lighting devices having the same shape adjacent to each other or arranging lighting devices having related shapes adjacent to each other. It becomes.
