The positions of the electrodes 103 and 104 are not particularly limited as long as the electrodes 103 and 104 are provided at the peripheral edge on the main surface 100a side. In the light emitting panel 100 according to the present embodiment, when the center line CL1 is assumed to be the X axis and the center line CL2 is assumed to be the Y axis, the electrode 103 is provided in the peripheral portion located in the third quadrant, and is located in the fourth quadrant. An electrode 104 is provided on the peripheral edge. By arranging the electrodes 103 and 104 in this way, the connection relationship of terminal portions provided in a lighting device to be described later can be made a unique relationship.

  Referring to FIGS. 3 to 5, the light-emitting panel 100 includes a light-emitting layer 101 and an electrode 103 as a part thereof, and is electrically connected to a conductor 102 and an electrode 104 located on one surface side of the light-emitting layer 101.

(Embodiment 1: Lighting device 1)
Next, referring to FIGS. 7 to 14, lighting apparatus 1 according to the present embodiment will be described. The lighting device 1 according to the present embodiment is assumed to be installed on a ceiling or the like. FIG. 7 is a perspective view of the lighting device 1 looking up the appearance, and FIG. FIG. 9 is a view seen from the outlet side of the illuminating device 1, and FIG. 10 is a view seen from the illumination opening side of the illuminating device.

  11 is a cross-sectional view taken along line XI-XI in FIG. 10, FIG. 12 is a cross-sectional view taken along line XII-XII in FIG. 9, and FIG. 13 is a state in the middle of pulling out the light emitting panel 100 of the lighting device 1. FIG. 14 is a cross-sectional view showing a state in which the light emitting panel 100 of the lighting device 1 is completely pulled out.

  First, referring to FIG. 7 to FIG. 10, the lighting device 1 has a storage housing 10 having a support member 13 provided with a side plate 11, a top plate 12, and an opening 13 h. The storage housing 10 has a rectangular parallelepiped shape as a whole. On the support member 13 side of one side plate 11 of the storage housing 10, an outlet 11 h for pulling out the light emitting panel 100 stored in the storage housing 10 is provided. Further, a cutout 14 for easily pulling out the light emitting panel 100 is provided on the support member 13 side of the outlet 11h.

  Next, referring to FIG. 11 and FIG. 12, the light emitting panel pack 1000 is housed in the housing 10. In the present embodiment, the light emitting panel pack 1000 is a state in which three light emitting panels 100 are stacked. The number of the light emitting panels 100 of the light emitting panel pack 1000 is appropriately changed according to the specifications required for the lighting device 1 and is not limited to three.

  A pressure plate 16 and a plurality of coil springs 17 are provided on the inner surface of the light emitting panel pack 1000 on the top plate 12 side to constitute a pressurizing mechanism that presses the light emitting panel 100 against the support member 13 side. The number and installation of the coil springs 17 are not particularly limited. However, from the viewpoint of crimping the electrodes 103 and 104 to the terminal portion 15, it is preferable to dispose the coil spring 17 at a position facing the terminal portion 15. In addition, if a pressurization force can be obtained, it will not be limited to the coil spring 17, but a well-known elastic member can be used.

  In addition, when the light emitting panel 100 can be pressed against the support member 13 by its own weight, it is not always necessary to provide a pressure mechanism that presses the light emitting panel 100 against the support member 13.

  The opening area of the opening 13 h provided in the support member 13 is provided in substantially the same area as the light emitting surface 105 a of the light emitting panel 100, and the peripheral portion of the light emitting panel 100 is supported by the support member 13. The irradiated light illuminates the object from the opening 13h. It is also possible to dispose a transparent glass plate in the opening 13h.

  In the support member 13, a terminal portion 15 that is in contact with the electrodes 103 and 104 and supplies electricity to the electrodes 103 and 104 is provided at a position facing the electrodes 103 and 104 provided on the light emitting panel 100. As described above, since a direct current is applied between the electrode 103 and the electrode 104, it is important to make the positive pole and the negative pole coincide between the electrode and the terminal portion.

  Therefore, in the present embodiment, as described above, by adopting the configuration in which the electrode 103 is provided in the peripheral portion located in the third quadrant and the electrode 104 is provided in the peripheral portion located in the fourth quadrant, the light-emitting panel is adopted.

In the drawing, for the purpose of understanding the structure, the thickness direction is shown larger than the width direction, but the height of the terminal portion 15 is about 0.1 mm to about 0.3 mm. Therefore, the recessed area of the electrodes 103 and 104 can be easily mounted on the terminal portion 15 by the operator pulling the light emitting panel 100.

  Next, referring to FIG. 14, the light emitting panel 100 is further slid in a plane direction parallel to the light emitting surface 105 a, and the light emitting panel 100 is completely removed from the housing case 10. Thereby, the light emitting panel pack 1000 moves to the support member 13 side based on the urging force by the pressurizing mechanism, and the light emitting surface 105a of the next new light emitting panel 100 is exposed from the opening 13h. Further, when the electrodes 103 and 104 of the light emitting panel 100 and the terminal portion 15 are in contact with each other, the light emitting surface 105a of the light emitting panel 100 emits light.

Without this, the next new light emitting panel 100 can be arranged at an appropriate position of the support member 13. As a result, the replacement work of the light emitting panel 100 can be easily completed.

  Further, since the light emitting panel 100 can be replaced only by sliding the light emitting panel 100 that has reached the replacement time, it is possible to prevent the next new light emitting panel 100 from being damaged or scratched. Moreover, the structure of the illuminating device 1 becomes simple and the low cost of the illuminating device 1 can be implement | achieved.
