  • the drive circuit 64b does not drive the second light emitting unit of the organic EL light emitting panel 91. Therefore, since the second light emitting unit does not emit light, no light is emitted from the second light emitting region 93a. Since the light emitted from the first light emitting region 92a is sufficient for illumination inside the accessory case 31, which is a narrow storage space, energy saving can be achieved.
  • a user such as a vehicle occupant can operate the handle 74 to pull out the organic EL light emitting panel 91 from the holder 18 and move it in the direction indicated by the arrow B.
  • the extraction detecting unit 65 detects that the organic EL light emitting panel 91 exists at the extraction position, and thereby the control unit 66 generates a drive command for the drive circuits 64a and 64b.
  • the drive circuit 64a continuously supplies a drive current to the first light emitting unit of the organic EL light emitting panel 91 in response to the drive command, the light emission of the first light emitting unit is maintained, and the light is emitted from the organic EL light emitting panel 91.
  • the light is emitted from one light emitting region 92a in a direction indicated by an arrow C.
  • the drive circuit 64b supplies a drive current to the second light emitting unit of the organic EL light emitting panel 91 in response to the drive command, the second light emitting unit emits light, and the light is emitted from the second light emitting region 93a of the organic EL light emitting panel 91. Similarly, the light is emitted in the direction indicated by the arrow C.
  • the emitted light from each of the first and second light emitting regions 92a and 93a of the organic EL light emitting panel 91 is directed into the vehicle interior, and the vehicle interior can be illuminated. Since the interior of the vehicle is illuminated by the light emitted from each of the first and second light emitting regions 92a and 93a, the interior can be illuminated brightly even in a large interior.
  • FIGS. 15 (a) and 15 (b) show a light-emitting device 100 for putting accessories of Example 5 of the present invention.
  • a light reflecting plate 101 is added to the light emitting device 70 shown as the third embodiment.
  • the light reflecting plate 101 is disposed on the inner wall surface of the holder 18 facing the light emission opening 71.
  • the organic EL light emitting panel 99 is not held, the light emission opening 71 is formed. Exposed to the outside.
  • the light reflecting plate 101 has the same size as the light emitting opening 71.
  • the light reflecting plate 101 may be formed by attaching a metal plate such as an aluminum plate or a silver plate to the inner wall surface of the holder 18 or may be formed by performing a metal plating process on the inner wall surface of the holder 18.
  • the organic EL light emitting panel 99 has a light emitting surface 99b (FIG. 17B) on the opposite surface in addition to the light emitting surface 99a.
  • the inside of the organic EL light emitting panel 99 is shown in FIG. 16 (b) as a cross-section of the XY portion of FIG. 16 (a).
  • the transparent electrode anode 82 and the light emitting layer are provided on the flexible transparent substrate 81.
  • the organic functional layer 83 includes a cathode 84a of a flexible transparent electrode, and a sheet-like flexible transparent member 85 are sequentially stacked.
  • the anode 82, the organic functional layer 83, and the cathode 84 a are organic EL elements, and a plurality of these organic EL elements may be formed on the transparent substrate 81.
  • the organic EL light emitting panel 99 of Example 5 emits light on both sides because the cathode 84a is formed of a flexible transparent material.
  • the on / off switch 42 is turned on and a driving current is supplied to the organic EL light emitting panel 99.
  • the light emitting panel 99 emits light.
  • Light emitted from the anode 82 side of the organic functional layer 83 is emitted in the direction indicated by the arrow A from one light emitting surface 99a.
  • a part of the light emitted from the cathode 84 a side of the organic functional layer 83 is reflected by the light reflecting plate 101, passes through the organic EL light emitting panel 99, and is emitted from one light emitting surface 99 a. Since the organic EL light emitting panel 99 is housed in the holder 18, a part of the emitted light on the light emitting surface 99 a illuminates the interior of the accessory case 31 through the light emitting opening 71.
  • a user such as a vehicle occupant can operate the handle 74 to move the organic EL light-emitting panel 99 out of the holder 18.
  • the organic EL light emitting panel 99 moves in this way, light is emitted from both light emitting surfaces 99a and 99b of the organic EL light emitting panel 19, so that the emitted light is not only in the accessory case 31 indicated by the arrow C, but also in the arrow D.
  • the vehicle interior can be illuminated in a wide range.
  • the light emitting device for compartment accessory is shown, but the present invention is not limited to this and can be applied to a storage box such as a furniture drawer. Further, the present invention is not limited to a storage box for a vehicle such as an automobile or a two-wheeled vehicle, but can be applied to a storage box for a vehicle such as a ship or an airplane.
  • the organic EL light-emitting panel is shown as the surface light-emitting panel, but the configuration of the organic EL light-emitting panel is not limited to that shown in the embodiment.
  • the present invention may use a light emitting panel other than the organic EL light emitting panel, for example, a light emitting panel in which a plurality of light emitting elements are arranged to enable surface light emission.
