The light emitting element is not particularly limited as long as it can emit light when current is supplied through the electrode terminals 14 and 16. For example, a light emitting diode (LED), an electroluminescent element (EL element), or the like is used. it can. In particular, from the viewpoint of reducing the thickness, a light emitting sheet using an EL element is preferable.

A pair of power supply terminals 34 and 36 are formed on the opposite surfaces of the inner wall surface facing each other in the groove portion 32 in separate steps having a gap G2 in the depth direction of the groove portion 32 (the Y1 direction). The power supply terminals 34 and 36 of the socket are terminals connected to a power supply, and each power supply terminal 34 and 36 is continuously provided along the groove portion 32. Further, when the light emitting sheet 10 is mounted in the groove portion 32, the power supply terminal pairs 34 and 36 are connected to each other, that is, the anode terminal 14 of the light emitting sheet 10 and the anode terminal 34 of the socket 30 are connected. The cathode terminal 16 and the cathode terminal 36 of the socket 30 are formed to be connected. What is necessary is just to set the distance between the power supply terminals of the same polarity which oppose in the groove part 32 so that it may connect with the corresponding electrode terminals 14 and 16 of the light emitting sheet 10, and the attachment or detachment of the light emitting sheet 10 does not have trouble.

Further, as shown in FIG. 2, the power terminals 34 and 36 of the socket 30 are provided in the groove portion 32 via a cushion member 38 such as a hard sponge or rubber as means for pressing the mounting portion 18 of the light emitting sheet 10. It is preferable that If each power supply terminal 34, 36 is provided via the cushion member 38, each power supply terminal 34, 36 is attached to the light emitting sheet 10 by the elasticity of the cushion member 38 when the light emitting sheet 10 is attached to the groove 32.

The cushion member 38 that presses the mounting portion 18 of the light emitting sheet 10 only needs to be provided on the power terminal pairs 34 and 36 formed on at least one side.
In addition, a conductive cushion member may be provided as a power supply terminal, or a support member that directly supports the light emitting sheet 10 may be provided separately from the power supply terminals 14 and 16.

<Light emitting device>
As shown in FIG. 4, by attaching the light emitting sheet 10 to the groove portion 32 of the socket 30, the electrode terminals 14 and 16 of the light emitting sheet 10 are electrically connected to the corresponding power terminals 34 and 36 of the socket 30, respectively. To do. The light emitting sheet 10 emits light when energized through the power terminals 34 and 36 of the socket 30. As a power source to which the power terminals 34 and 36 are connected, a battery may be provided inside the socket 30 or each power terminal 34 and 36 of the socket 30 may be connected to an external power source via a power cord. It may be. A part of a power circuit such as a transformer circuit or an inverter circuit may be provided inside the socket 30 and connected to another external power circuit via a power cord. The socket 30 may be provided with an ON / OFF switch and a current or voltage adjustment knob.

  In the groove portion 32 of the socket 30, a pair of power supply terminals 34 and 36 are formed on the opposite inner wall surfaces, so the orientation of the front and back sides of the light emitting sheet 10 is not limited when mounted. The electrical connection between the light emitting sheet 10 and the socket 30 is ensured regardless of which of the front and back surfaces is inserted into the groove 32. Further, since the power supply terminals 34 and 36 are continuously formed in the groove portion 32 of the socket 30 along the length direction (Y2 direction), the degree of freedom of the mounting position of the light emitting sheet 10 is large. Therefore, the light emitting sheet 10 can be mounted in the groove portion 32 of the socket 30 without paying special attention, and the mounting portion 18 of the light emitting sheet 10 is locked at an arbitrary position of the groove portion 32 to emit light. Can do.

Further, the degree of freedom of the size of the light emitting sheet 10 is large, and various sizes of light emitting sheets can be shared by one socket 30. For example, as shown in FIG. 5, two light emitting sheets 10 and 20 of an arbitrary size, or three or more light emitting sheets can be attached to one socket 30 to emit light simultaneously.
Thus, in the light emitting device that combines the light emitting sheet 10 and the socket 30 according to the present embodiment, handling becomes simple.

-Second embodiment-
In the light emitting device according to the second embodiment shown in FIG. 6, a pair of power supply terminals 34 and 36 is formed only on one side of the inner wall surfaces facing the groove 32 of the socket 30. The configuration of the light emitting sheet 10 is the same as that of the first embodiment. In such a combination, the light emitting sheet 10 is oriented so that the electrode terminals 14 and 16 of the light emitting sheet 10 and the power supply terminals 34 and 36 in the groove 32 of the socket 30 are in contact with each other. Just install it. In addition, the power supply terminals 34 and 36 in the groove part 32 are provided via the cushion member 38, and the cushion member 38 is also provided on the opposing inner wall surface. Therefore, also in this embodiment, the light emitting sheet 10 can be easily attached and detached by the elasticity of the cushion member 38, and the electrical connection between the electrode terminals 14 and 16 of the light emitting sheet 10 and the power terminals 34 and 36 of the socket 30 is achieved. Connection is ensured and the mounted light emitting sheet 10 can be stably supported.

-Third embodiment-
In the light emitting device according to the third embodiment shown in FIG. 7, a pair of electrode terminals 14 and 16 are formed on both surfaces of the mounting portion 18 of the light emitting sheet 10. The configuration of the socket 30 is the same as that of the second embodiment. For example, if a pair of electrode terminals 14 and 16 formed on each surface of the light emitting sheet 10 are connected to the same light emitting element, the electrode terminals 14 and 16 formed on either surface are connected to the power source. It can be connected to the terminals 34 and 36 to emit light. Alternatively, if light emitting elements are formed on both surfaces of the substrate 11 such as plastic to form a light emitting sheet that emits light through separate circuits, the light emitting elements on either surface can be selectively made to emit light. .

-Fourth embodiment-
The light emitting device according to the fourth actual embodiment shown in FIG. 8 is a combination of the light emitting sheet 10 according to the third embodiment and the socket 30 according to the first embodiment. A pair of electrode terminals 14 and 16 are formed on both surfaces, and a pair of power supply terminals 34 and 36 are formed on both surfaces of the inner wall surface facing each other in the groove 32 of the socket 30. With such a combination, for example, a light-emitting sheet in which light-emitting elements are formed on both sides as described above can simultaneously emit light on both sides.

Moreover, the shape of the electrode terminals 14 and 16 of the light emitting sheet 10 and the shape of the power terminals 34 and 36 of the socket 30 are not particularly limited, and can be appropriately selected.
For example, in the first to fourth embodiments, the electrode terminals 14 and 16 of the light emitting sheet 10 are concave portions in the mounting portion 18 of the light emitting sheet 10, but may be convex portions as shown in FIG. Good.

  Further, the electrode terminals 14 and 16 formed on the same surface of the light emitting sheet 10 may be formed in different stages so as to have a gap in the height direction of the mounting portion 18. The length of is not particularly limited. However, if each of the electrode terminals 14 and 16 is too long, when the light emitting sheet 10 is attached or detached, the light emitting sheet 10 is inclined and one electrode terminal (anode terminal or cathode terminal) is the power supply terminal of both of the sockets 30. Since there is a possibility of short-circuiting due to contact with 34 and 36 simultaneously, each electrode terminal 14 and 16 is preferably, for example, not more than half of the length of the mounting portion 18 (the length in the X2 direction in FIG. 1). For the same reason, it is preferable that each of the electrode terminals 14 and 16 is provided in the vicinity of the central portion instead of the end portion in the X2 direction.

For example, as shown in FIG. 10, the electrode terminals 14 and 16 may be provided with their positions shifted in the width direction (X2 direction) as well as the height direction (X1 direction) of the mounting portion 18. Good. However, as the distance in the width direction between the electrode terminals 14 and 16 increases, a short circuit is more likely to occur when the light emitting sheet 10 is attached / detached. Therefore, the displacement in the width direction of the electrode terminals 14 and 16 is preferably as small as possible.
The gap G in the height direction of the electrode terminal pairs 14 and 16 may be set as appropriate according to the size of the light emitting sheet 10 and the like. However, if the gap G is too narrow, a short circuit is likely to occur. Since the light emitting region 22 is reduced by the increase in the thickness, it may be in the range of about 0.1 mm to 1 cm.

  On the other hand, the power supply terminals 34 and 36 provided in the groove 32 of the socket 30 are formed discontinuously in the length direction of the groove 32 (direction Y2 in FIG. 1) and are electrically connected. Also good. For example, as shown in FIG. 11, the power terminals of the same polarity are formed in a leaf spring shape that is divided in the longitudinal direction of the groove portion 32, and the leaf springs 36 </ b> A are connected by wiring 33 to be electrically connected. The width of each divided power supply terminal 36A is not limited, and may be appropriately designed to have a width of several mm to several cm, for example. In this way, by dividing the same-polarity power terminals formed in the same stage and combining the pressing means, even if a plurality of light-emitting sheets having different thicknesses are mounted, Since each power supply terminal 36A is movable according to the thickness, it is possible to emit light by reliably contacting the electrode terminals 14 and 16 of each sheet.

  The form of the divided power supply terminals is not particularly limited. For example, as shown in FIG. 12, a spherical power supply terminal 36B is supported by a spring 39, and a part of the sphere 36B is exposed from the outer frame 35. It is good. Moreover, as shown in FIG. 13, the divided | segmented power supply terminal 36C may be provided in cushion members 38, such as hard sponge and rubber | gum.

The electrode terminals provided on the light emitting sheet 10 are not limited to two stages, and the electrode terminals including the pair of electrode terminals 14 and 16 are formed in three or more stages on at least one surface of the mounting portion 18 of the light emitting sheet 10. Two or more circuits for driving the light emitting element may be formed. For example, as shown in FIG. 14, two light emitting areas A and B are provided in the surface of the light emitting sheet 10A, and two light emitting elements are used so that the light emitting elements in the light emitting areas A and B emit light independently. Circuits are formed with electrode terminal pairs 14a, 16a, 14b, and 16b corresponding to the regions A and B, respectively. Here, the electrode terminal 16a located on the upper stage of the electrode terminal pair 14a, 16a connected to the light emitting element in the light emitting region A, and the lower stage of the electrode terminal pair 14b, 16b connected to the light emitting element on the light emitting area B. By making the electrode terminal 16b to be the same polarity (cathode in FIG. 14), these electrode terminals 16a and 16b can be provided in the same step (height).
Note that the light-emitting sheet may be configured such that two or more light-emitting elements are stacked, and each electrode terminal may be formed in a different stage so that each light-emitting element emits light independently. Furthermore, a light-emitting sheet having two or more layers of light-emitting elements and having two or more patterns of light-emitting regions can be formed.

  The power supply terminals provided in the groove portion 32 of the socket 30 are not limited to two stages, and the power supply terminals including the pair of power supply terminals 34 and 36 are formed in three or more stages on at least one side of the opposing inner wall surface in the groove portion 32 of the socket 30. In addition, two or more circuits for the light emitting element of the light emitting sheet 10A may be formed. For example, when the light emitting sheet 10 having two patterns of the light emitting areas A and B as shown in FIG. 14 is used, the light emitting sheet is provided on at least one of the inner wall surfaces facing each other in the groove 32 as shown in FIG. Are provided with three stages of power supply terminals 34, 36, and 37 corresponding to the electrode terminals 14a, 16a, 16b, and 14b, and two circuits for each light emitting element (light emitting regions A and B) are formed. A socket 30A can be used. With such a combination, the light emitting areas A and B of the light emitting sheet 10A can be caused to emit light independently. It should be noted that two types of sockets corresponding to one set of the two electrode terminal pairs 14a, 16a, 16b, and 14b of the light emitting sheet 10A are prepared, and the sockets are exchanged according to the light emitting area desired to emit light. Also good.

  In addition, a terminal other than the pair of electrode terminals 14 and 16 connected to the light emitting element is formed on the mounting portion 18 of the light emitting sheet 10, and light is emitted on at least one side of the inner wall surface facing the groove portion 32 of the socket 30. A light emitting device in which terminals corresponding to the other terminals of the sheet are formed can also be provided. For example, the two sets of electrode terminal pairs 14a, 16a, 14b, and 16b of the light emitting sheet 10A shown in FIG. 14 are all connected to the light emitting element, but such two sets of electrode terminal pairs 14a, 16a, 14b, One set of electrode terminals of 16b is not for light emitting elements, but is applied to functions other than light emitting elements, such as for control signal terminals and audio signal terminals, and the grooves 32 of the socket 30A also correspond to those terminals. Another terminal may be formed.

  Further, for example, when an inorganic EL element is used as the light emitting element, there is a problem that vibration and noise are likely to occur due to AC driving. In order to suppress the occurrence of such vibrations, a compensation electrode is provided between one electrode of the pair of electrodes via an insulating layer, and an AC voltage having an opposite phase is applied between the opposing electrodes. A method for canceling the generated vibration is known (see, for example, JP-A-2005-116284). In the case of a light emitting sheet having an inorganic EL element having such a compensation electrode, in addition to the electrode terminal pairs 14 and 16 and the power supply terminal pairs 34 and 36 for the anode and cathode, the light emitting sheet 10 includes a compensation electrode Electrode terminals, and corresponding power terminals are provided in the grooves 32 of the socket 30 in different stages. And the vibration and noise can be reduced by shifting the phase of the AC power source applied between the opposing electrodes.
