Here, as shown in FIG. 2, the sheet-like EL light-emitting element 5 is a flexible thin EL light-emitting element in which a light-emitting pattern 6 according to the purpose is formed, and has one edge of a rectangular outer shape. A pair of electrodes 7 are formed so as to be exposed at a predetermined interval. In each drawing of the embodiment, the light emission pattern 6 of the sheet-like EL light-emitting element 5 is clearly indicated by oblique lines as necessary.

  As shown in FIG. 1, the main body 2 has a battery storage portion 9 for detachably storing a battery 8 as a power source, and a power switch 10, and is connected to the battery 8 to be a sheet-like EL light emitting element. And a drive circuit 11 that drives the light emission of 5 by alternating current. A pair of output terminals 12, 12 connected to the drive circuit 11 are arranged at a predetermined interval on the upper surface of the main body 2 facing the upper cover 3. In each drawing of the embodiment, the output terminal 12 is indicated by hatching as necessary. As shown in FIG. 2, the distance between the pair of output terminals 12 and 12 is the distance between the pair of electrodes 7 and 7 provided on the sheet-like EL light-emitting element 5 to be exhibited and emitted by the EL light-emitting device 1a. When the sheet-like EL light-emitting element 5 is sandwiched between the main body 2 and the upper cover 3, the pair of electrodes 7 and 7 of the sheet-like EL light-emitting element 5 are connected to the pair of outputs.

4). 4th Embodiment (4th example, FIGS. 11-14)
As shown in FIGS. 11 to 12, the EL light emitting device 1e of the fourth example includes a main body 20 (first base member) and an upper cover, which are substantially rectangular parallelepiped casings facing each other with a gap S therebetween. 30 (second base member) and a side body 31 that connects these long sides are formed in a substantially U-shaped cross section as a whole. The dimensions (width and height) of the gap S between the main body 20 and the upper cover 30 are set to such an extent that it is easy to insert the sheet-like EL light emitting element 5 and the operator's finger cannot enter in consideration of safety. ing.

  As shown in FIG. 11, a main body 20 has a battery storage portion 9 for detachably storing a battery 8 as a power source, and a power switch 10, and is connected to the battery 8 to be a sheet-like EL light emitting element. And a drive circuit 11 that drives the light emission of 5 by alternating current. A pair of output terminals 22 and 22 connected to the drive circuit 11 are disposed at a predetermined interval on the lower surface of the upper cover 30 facing the main body 20. The distance between the pair of output terminals 22 and 22 is set to be equal to the distance between the pair of electrodes 7 and 7 provided on the sheet-like EL light-emitting element 5 to be exhibited and emitted by the EL light-emitting device 1e. When the sheet-like EL light-emitting element 5 is sandwiched between the main body 20 and the upper cover 30, the pair of electrodes 7, 7 of the sheet-like EL light-emitting element 5 are in contact with the pair of output terminals 22, 22.

In this state, if the power switch 10 is turned on, power can be stably supplied to the sheet-like EL light-emitting element 5 via the drive circuit 11 to drive light emission.

  In the fourth example, the main body 20 can be detachably attached to a desired position by an attachment / detachment mechanism (not shown) (a magnet, an adhesive layer, a suction cup, a double-sided tape and other removable attachment means). If the main body 20 is attached to a desired position by the attachment / detachment mechanism, the sheet-like EL light-emitting element 5 can be displayed at the position to emit light. For example, similarly to FIG. 3 showing the first example, if the main body 20 is attached to an arbitrary position on the wall, the light emitting display can be performed in a state where the sheet-like EL light-emitting element 5 is displayed at an arbitrary position on the wall. .

Furthermore, although the output terminal 22 serves as both the holding means and the power supply means for the sheet-like EL light emitting element 5, the output terminal 22 may be configured to perform only power supply and provide a separate holding means.

  According to the EL light emitting device 1e of the fourth example described above, the same sheet-like EL light emitting element 5 is repeatedly attached and detached because the output terminal 22 is movable up and down in addition to the effects of the first example. In addition, the edge of the sheet-like EL light-emitting element 5 is prevented from hitting the output terminal 22 and damaging the periphery of the electrode 7.

  Each of the EL light emitting devices 1a to 1e of the first to fourth examples described above has a substantially rectangular parallelepiped shape as a whole, but the outer shape is not limited to the one described above. For example, as shown in FIG. A substantially triangular EL light-emitting device 1 f that holds the corners of the rectangular sheet-like EL light-emitting element 5 can also be provided.
