In particular, the chevron portion 10 of the reflecting structure 7 is formed so that the portions 10a facing the respective light emitting elements 11 are formed in a substantially triangular shape, and the light from the light emitting elements 11 is efficiently reflected. It is desirable that the height h of the chevron portion 10 is set to approximately half of the height H of the side surface portion 9 from the viewpoint of securing a light reflection amount toward the opening 7a. However, this relationship is not absolute and can change depending on the size of the reflecting structure 7 and the characteristics of the light emitting element 11.
A partition plate 12 made of a translucent member such as an acrylic plate is disposed on the outer surface of each side surface portion 9 in the reflective structure 7. The partition plate 12 is formed in a size that slightly protrudes from the rising end 9 a of the side surface portion 9. And the light diffusing plate 13 is arrange | positioned at the protrusion end 12a of the partition plate 12 so that the opening part 7a may be obstruct | occluded.

Next, the manufacturing method of the above-mentioned reflective structure 7 is demonstrated with reference to FIGS. First, as shown in FIG. 5, the plate-like member is cut and processed so that a rectangular bottom surface portion 8 and a substantially rectangular side surface portion 9 are integrally formed on each side portion 8 a of the bottom surface portion 8. To do. Next, the cut portions 7b and 7b are formed so as to form a cross shape from the center portion of the bottom surface portion 8 toward the center portion of the side portion 8a. Next, holes 8 b are formed in the respective corner portions of the bottom surface portion 8. Note that the cutting and processing of the bottom surface portion 8 and the side surface portion 9, the formation of the cut portion 7b, and the formation of the hole 8b can be performed in a lump or can be performed at the same time. Further, as the plate-like member, for example, a member in which a light-reflective sheet is integrally superimposed on one surface of a metal plate such as an aluminum plate that can be easily bent is suitable.
Next, as shown in FIGS. 6 to 7, the side portions 9 are bent at substantially right angles so that each side portion 9 rises in the same direction from the dotted line portion corresponding to the side portion 8 a shown in FIG. 5. Next, the central portion 10 is formed by pushing up the central portion of the bottom surface portion 8 by using, for example, a chevron-shaped molding die. The angled portion 10 is formed in the entire circumferential direction (four directions in this embodiment) by bending from the dotted line portion shown in FIG. The inclined surface 10a is formed so as to face the corner portion, and has a substantially triangular shape. In particular, the formation of the mountain-shaped portion 10 can be performed smoothly because the cut portions 7b are formed in a cross shape in advance. Note that the side portion 9 can be bent and the crest portion 10 can be processed simultaneously. The box-shaped reflection structure 7 is manufactured through the above processing steps.

  The reflecting structure 7 according to the present invention is preferably manufactured by the above-described method, but can also be manufactured by a method different from this method. For example, the first method is to process only a metal plate excellent in bending workability into a box shape by the same method as in FIGS. 5 to 7, and then integrate a light-reflective sheet on the box-shaped inner surface. It is a method to paste. The second method is basically processed in the same manner as the first method using only a metal plate excellent in bending workability, but does not form the cross-shaped cut portion 7b shown in FIG. In this method, the central portion of the bottom surface portion 8 is pushed up by a mountain-shaped molding die to form the mountain-shaped portion 10. The reflective surface of the box-shaped inner surface can be formed by attaching a light reflective sheet, vapor-depositing or plating a light reflective metal, or the like.

Next, the 2nd Example of the illuminating device concerning this invention is described with reference to FIG. In the figure, A1 to A4 are the same as the illumination device shown in FIGS. As shown in FIG. 3A, the connector 2 of the illumination device A2 is opposed to the connector 3 of the illumination device A1, the connector 2 of the illumination device A3 is opposed to the connector 3 of the illumination device A2, and the connector 4 of the illumination device A2 is illuminated. The connector 5 of the device A4 is opposed. Next, as shown in FIG. 6B, by joining the connectors, a T-shaped illumination device is completed, and surface illumination can be performed.
The combination form of each lighting device can be arbitrarily selected. For example, when screen-like surface illumination is required, it can be achieved by increasing the planar coupling relationship using connectors arranged on four sides of the base portion 1. When it is desired to display characters, the respective lighting devices may be combined so that the characters are completed.

  FIG. 9 shows a third embodiment of the illumination device according to the present invention. In the same figure, A1 to A4 are the same as the lighting apparatus shown in FIGS. 1 to 4, but the pins (insertion connecting portions) 2a of the respective connectors 2 are bent substantially at right angles as shown in FIG. Is different. Each of the lighting devices A1 to A4 configured as described above is configured in a substantially cylindrical shape by inserting and coupling the pins 2a of the respective connectors 2 to the respective connectors 3, as shown in FIG. Yes. The length of the cylindrical portion can be freely changed by appropriately coupling the lighting device in the longitudinal direction. In this embodiment, the form is configured as a rectangular cylinder, but it may be configured in an arbitrary shape such as a triangle. At this time, it is necessary to change the bending angle of the pin of the connector.

FIG. 10 shows a fourth embodiment of the lighting device according to the present invention. The basic configuration is the same as that of the lighting device shown in FIGS. A different point is that the reflective layer 14 is formed on the outer surface of the partition plate 12 disposed in the outer peripheral portion of the side surface portion 9 in the reflective structure 7. The reflection layer 14 is formed on the outer surface portion of the partition plate 12 corresponding to the space between the rising edge 9 a of the side surface portion 9 and the light diffusion plate 13. The above-mentioned reflective layer 14 is formed, for example, by attaching a light reflective sheet or a mirror sheet, or vapor-depositing a metal having a light reflective function.
By forming such a reflective layer 14, light leaks from the gap formed between the rising end 9 a of the side surface portion 9 and the light diffusion plate 13 to the partition plate side, and this leaked light is reflected by the reflective layer 14. In order to reach the light diffusion plate portion that is reflected and faces the rising edge 9a of the side surface portion 9, the brightness of the peripheral portion of the light diffusion plate 13 is reinforced. That is, an effect is obtained in which a low illuminance portion (dark portion) generated in the light diffusion plate portion facing the rising edge 9a of the side surface portion 9 can be relaxed.
In particular, as shown in FIG. 8, for example, when a surface illumination device is realized by combining a plurality of illumination devices A in a plane, it is possible to effectively alleviate the occurrence of shadows in adjacent portions of the individual illumination devices. It is possible to increase the commercial value of the lighting device.

The illuminating device A is substantially the same as the embodiment shown in FIGS. 1 to 4 except that a connector having an insertion connection portion is arranged only at one place on one surface of the base portion 1. On the other hand, the mounting member B includes a panel in which partition portions 15 having substantially the same size as the lighting device A are formed in length and breadth, and a receiving side disposed in each partition portion 15 corresponding to the connector of the lighting device A. Connector 16.
In the example of illustration, the illuminating device A is arrange | positioned at the attachment member B so that characters 1, 2, 3, 4, 5, etc. may be displayed, and each is mutually connected by the connector. In particular, when there is a possibility that the coupling state between the connectors may be impaired due to vibration or the like, it is desirable to use attachment means such as screws together. Moreover, although the light diffusing plate is arranged on the front side of each lighting device A, it can be omitted and a common light diffusing plate can be arranged on the front surface of the panel.
According to this embodiment, a variety of displays other than character display are possible by providing a large number of partition sections 15 on the panel, and various advertisements and promotions can be expected, and the size of the lighting device A can be reduced. If this is done, it is possible to deal with finer grain. Note that the mounting member B can be configured in a suitable form depending on the application, such as a cylindrical shape or a curved shape, in addition to a planar configuration, and the mounting position and form of each connector can be changed as appropriate. Moreover, the form of the illumination device A can also be selected other than the quadrangle.
Moreover, this illumination system can be applied for general illumination. According to this system, the number of illumination devices A arranged on the mounting member B can be changed as appropriate according to the required illuminance on the surface to be illuminated, so that the illuminance on the surface to be illuminated can be simply and appropriately maintained. In addition, in the case of periodic maintenance or repair, it is only necessary to simply insert and remove the lighting device A, so that efficient work can be performed and maintenance costs can be reduced.
Further, in this illumination system, if a plurality of light emitting elements having different emission colors are arranged for each corner portion of the reflecting structure in the illumination apparatus A, and a control device capable of controlling the amount of light for each light emission color is provided. Since the display color of each lighting device can be arbitrarily set, the display effect can be further enhanced.

  It should be noted that the present invention is not limited to the above-described embodiments, and can be appropriately modified within the scope not departing from the gist of the present invention. For example, the plate-like member constituting the reflective structure is preferably a metal plate, but may be a resin material or the like, and the reflective structure can be processed by resin molding. The number of light emitting elements arranged at each corner portion or each side portion of the reflecting structure can be set to an appropriate number such as two or three more than one according to the brightness expected of the apparatus. Further, an element other than the light emitting diode can be applied as the light emitting element. The lighting circuit can connect multiple light emitting elements in series or in parallel in relation to the power supply voltage, the forward voltage of the light emitting elements, etc., and the resistance value of the resistor as a protective resistor Is also set appropriately. Further, the connector is not limited to a plug-in type or a receiving type, and the location of the connector can be set to an appropriate location according to the application.
