Description

  The present invention relates to an organic EL (Electro Luminescence) module mainly used as illumination. The present invention also relates to an attachment structure when attaching the organic EL module to a wall surface or the like.

  In recent years, organic EL modules have attracted attention as a lighting device that can replace incandescent lamps and fluorescent lamps, and many studies have been made.

Here, the organic EL module is obtained by applying a sealing structure and a casing to an organic EL device. In addition, the organic EL device is formed by laminating an organic EL element on a substrate such as a glass substrate, a transparent resin film, or a metal sheet, and forming a power feeding structure for feeding power to the organic EL element.
And an organic EL element makes two electrodes which one or both have translucency oppose, and laminated | stacked the light emitting layer which consists of an organic compound between this electrode. The organic EL device emits light by the energy of recombination of electrically excited electrons and holes.
That is, the organic EL module is a self-luminous device and can emit light of various wavelengths by appropriately selecting a material of the light emitting layer.

  In addition, the organic EL module has a feature that the thickness is extremely small and lighter than incandescent lamps, fluorescent lamps, and LED lighting, and light is emitted in a planar shape. Furthermore, since the organic EL module has higher luminous efficiency than incandescent lamps and fluorescent lamps, the organic EL module has the features of low power consumption and low heat generation.

  By the way, in recent years, lighting devices in living spaces are required not only to function as direct lighting but also to have additional functions such as improving the design of living spaces. For example, Patent Document 1 discloses a structure in which a light emitting panel (organic EL module) including an organic EL element is provided and the light emitting panel is pivotally supported by a frame member. And the illumination device of patent document 1 reflects the direct illumination which irradiates the irradiation light to the living space side directly by the user rotating the said light emission panel, and reflects the irradiation light to the living space side. It is possible to switch to indirect illumination that irradiates light.

Further, as shown in FIG. 2, the protruding length W1 of the support portions 86 and 87 from the mounting portion 85 is longer than the rotation radius R1 of the organic EL module 2.

  Then, the positional relationship of each member is demonstrated according to the general assembly procedure of the organic EL module 2. FIG.

First, the process of installing the first conductive member 6 on the base member 7 will be described. Since the steps for installing the first conductive members 6a to 6c on the base member 7 are the same, the first conductive member 6b will be described unless otherwise specified, and the first conductive members 6a and 6c will be described. Omitted.
The first conductive member 6 b is bent and attached to the base member 7. Specifically, the electrode feeding portion 50 of the first conductive member 6b is bent so as to be an end (FIGS. 13A to 13B), and is folded at the edge of the overlapping portion 53 (FIG. 13B). To FIG. 13 (c)).

Then, a part of the first conductive member 6b is inserted into the through hole 62 of the base member 7, and the first storage space 61 is further bent inward so as to be filled with the first conductive member 6b (FIG. 13C). To FIG. 13 (d)).
At this time, as shown in FIG. 14, a part of the first conductive member 6b (surface opposite to the conductive portion 51) is placed on the base member 7, and the conductive portion 51 is in the first storage space 61 (FIG. 10). Browse). The conductive portion 51 faces upward in the member thickness direction.
At this time, the conductive foil 40 in the exposed region 45 and the conductive foil 40 in the covering region 47 sandwich the base member 7 as shown in FIG. The surface opposite to the conductive portion 51 is bonded to the base member 7.

  Further, as viewed from the whole, the first conductive members 6a, 6b, and 6c are arranged in parallel in the first storage spaces 73, 61, and 74 as shown in FIG. The first conductive members 6a, 6b, 6c are arranged at a predetermined interval from each other. Specifically, the distance between the first conductive members 6 a and 6 b is equal to the distance between the electrode portions 35 a and 35 b and / or the electrode portions 36 a and 36 b of the organic EL device 5. Similarly, the distance between the first conductive members 6b and 6c is equal to the distance between the electrode portions 35b and 35c of the organic EL device 5 and / or the electrode portions 36b and 36c. The electrode power supply portions 50a, 50b, 50c of the first conductive members 6a, 6b, 6c are arranged in a straight line in the width direction w. Similarly, the electrode power supply portions 52a, 52b, 52c are also in a straight line in the width direction w. Are lined up.

  The first conductive members 6a, 6b, 6c are inserted into the through holes 75, 62, 76 of the base member 7, respectively, and a part of the first conductive members 6a, 6b, 6c passes through the through holes 75, 62, 76 of the base member 7, It protrudes to the back side (upper side) of the base member 7. That is, the first conductive members 6 a, 6 b, 6 c electrically connect the front surface side of the base member 7 and the back surface side of the base member 7 via the conductive foil 40.

Next, the first conductive members 6a, 6b, 6c and the base member 7 integrated by the above-described process are placed on the organic EL device 5 assembled by a separate process.
At this time, the electrode portions 35a and 36a of the organic EL device 5 are in contact with the electrode power feeding portions 50a and 52a of the first conductive member 6a. Similarly, the electrode portions 35b and 36b of the organic EL device 5 are in contact with the electrode power supply portions 50b and 52b of the first conductive member 6b, and the electrode portions 35c and 36c of the organic EL device 5 are electrode power supply of the first conductive member 6c. The parts 50c and 52c are in contact.

Thereafter, a caulking material is applied to the side surface of the organic EL device 5 and a part of each of the first conductive members 6a, 6b, 6c to form the coking member 12.
At this time, the caulking member 12 is formed so as to cover the side surface of the organic EL device 5 and a part of each of the first conductive members 6a, 6b, and 6c. The outer side surface of the caulking member 12 is flush with the end surface of the base member 7 as shown in FIG.
The raw material for the caulking member 12 used here is not particularly limited as long as it is an adhesive and solidifies raw material, but an insulating thermosetting resin is preferable. In particular, a resin having waterproof properties is more preferable.

After the formation of the caulking member 12, the second conductive members 8a and 8b are installed in the second storage spaces 66 and 78 of the base member 7 as shown in FIG.
At this time, the conductive portions 51a, 51b, 51c of the first conductive members 6a, 6b, 6c are in contact with the lower surfaces of the second conductive members 8a, 8b. Further, as shown in FIG. 15, conductive spaces 111 and 112 having the second conductive members 8a and 8b as bottom surfaces are formed in the second storage spaces 66 and 78, respectively. The conductive spaces 111 and 112, the cutout holes 100 and 101, and the cutout grooves 102 and 103 are continuous in a straight line.

As shown in FIG. 15, the feeding electrodes 10 a and 10 b are attached across the conductive spaces 111 and 112, the cutout holes 100 and 101, and the cutout grooves 102 and 103.
At this time, part of the positioning portions 107a and 107b and the elastic members 110 and 110 are located in the cutout holes 100 and 101, and the conductive portions 106a and 106b are located in the conductive spaces 111 and 112. The rotary shaft portions 105a and 105b are located in the notch grooves 102 and 103, respectively.
The elastic members 110 and 110 are provided in a state where the end surfaces of the positioning portions 107a and 107b of the main body members 108a and 108b are urged. The outer end surfaces in the longitudinal direction 1 of the conductive portions 106 a and 106 b are in contact with the side wall portion 65 of the base member 7. Most of the rotating shaft portions 105 a and 105 b are exposed to the outside of the base member 7 through the notched grooves 102 and 103. That is, most of the rotation shaft portions 105 a and 105 b protrude from the base member 7. A predetermined space is provided between the conductive portions 106a and 106b and the side wall portions 65 and 77 on the intermediate portion 54 side, and a space is formed. The power feeding electrodes 10a and 10b are arranged on the same straight line and form a single rotation axis.

  Thereafter, the pressing plate 11 is placed on the top surface portion 63 of the base member 7 so as to press the power supply electrodes 10 a and 10 b against the second conductive member 8 as shown in FIG. 16.

The frame member 15 is attached so as to cover the connection portion between the caulking member 12 and the base member 7 from the outside of the caulking member 12, and the pressing plate 11 and the base member 7 are integrated.
At this time, in the frame member 15, the substrate 20 of the organic EL device 5 is placed on the bottom surface portion 81 as shown in FIG. 4, and the pressing plate 11 is located on the lower surface of the top surface portion 80. That is, the frame member 15 sandwiches the organic EL device 5, the base member 7, and the pressing plate 11 in the member thickness direction, and the organic EL device 5, the base member 7, and the pressing plate 11 are mutually connected by the rigidity of the standing wall portion 82. Preventing separation. When viewed from the power supply electrodes 10 a and 10 b, the power supply electrodes 10 a and 10 b are sandwiched between the second conductive member 8 and the pressing plate 11 in the thickness direction.

Further, the positioning portions 107a and 107b are sandwiched between the inner walls of the cutout holes 100 and 101 and the lower surface of the presser plate 11, and movements other than the longitudinal direction are restricted. Further, since the conductive portions 106a and 106b having a planar extension are disposed in the conductive spaces 111 and 112, the movement of the main body members 108a and 108b in the circumferential direction is restricted.
Rotating shaft portions 105a and 105b project outward from the insertion holes 83 and 84 of the frame member 15. That is, the rotating shaft portions 105a and 105b protrude in directions away from each other.
The rotating shaft portions 105a and 105b are urged so as to always protrude by the elastic restoring force of the elastic member 110. As described above, the organic EL module 2 takes a projecting posture in which the rotary shaft portions 105a and 105b project from the frame member 15 unless an external force is received as shown in FIG.
The above is a general assembly procedure of the organic EL module 2.

  Next, the positional relationship between each member of the organic EL module 2 and the attachment device 3 will be described along a general attachment procedure when attaching the organic EL module 2 formed by the above-described procedure to the attachment device 3.

The attachment part 85 is previously attached to the wall surface (in the present embodiment, the wall 117) with a known fastening element.
At this time, the support portions 86 and 87 are erected with respect to the wall 117. Further, the interval between the adjacent support portions 86 and 87 of the attachment device 3 is substantially equal to or slightly larger than the length of the organic EL module 2. For this reason, the rotation shaft portions 105a and 105b of the organic EL module 2 cannot be attached in a normal protruding posture (FIG. 17A).

Therefore, in this embodiment, when the user applies an external force, the posture of the organic EL module 2 is temporarily changed and attached to the attachment device 3.
Specifically, the user presses the rotating shafts 105a and 105b against the organic EL module 2 in the protruding posture (FIG. 17A), while inside the bearings 92 and 93 of the support portions 86 and 87. Rotating shafts 105a and 105b are inserted into (Fig. 17 (b)).
At this time, the organic EL module 2 takes a retraction posture in which most or all of the rotation shaft portions 105a and 105b are temporarily retracted into the frame member 15 as shown in FIG. 105 b hardly protrudes, and the organic EL module 2 can be interposed between the support portions 86 and 87. When the restoring force of the elastic member 110 returns from the retracted position to the protruding position, the rotating shaft portions 105a and 105b are inserted into the bearing portions 92 and 93, and the rotating shaft portions 105a and 105b are pivotally supported.

When attention is paid to the internal structure of the organic EL module 2 in this retracted position, the body members 108a and 108b are pushed against the elastic restoring force of the elastic member 110, and the conductive spaces 111 and 112 are moved toward the intermediate portion 54 in the longitudinal direction l. The conductive portions 106a and 106b move.
Moreover, since the space | interval between adjacent support parts 86 and 87 is substantially equal to the length of the frame member 15 of the organic EL module 2 as mentioned above, the rotating shaft parts 105a and 105b are the bearing parts 92 and 92 of the support parts 86 and 87, respectively. 93 is almost housed and hardly exposed to the outside. Therefore, the user does not accidentally touch the rotating shafts 105a and 105b while driving the organic EL module 2.

Next, the case of removing from the attachment device 3 will be described.
The organic EL module 2 is pushed into one of the support portions 86 and 87, and the organic EL module 2 is slid in the protruding direction of the support portions 86 and 87.
At this time, since the organic EL module 2 temporarily takes a retracted posture, the organic EL module 2 can be removed.

  As described above, the organic EL module mounting structure 1 of the present embodiment allows the organic EL module 2 to be easily removed.

  Next, an expected current flow when the organic EL module 2 of the present invention is attached to the attachment device 3 as shown in FIG. 18 and electrically connected to an external power source will be described. Here, the relationship between the current passing through the first conductive member 6a and the first conductive member 6b will be described, and the relationship between the current passing through the first conductive member 6c and the first conductive member 6b is the same, and is omitted. To do.

  The current flowing from the external power source reaches the bearing portion 92 via the conductive member 90 built in the support portion 86 of the attachment device 3, and is transmitted from the bearing portion 92 to the rotating shaft portion 105a of the power feeding electrode 10a. As shown in FIG. 19A, the current reaching the rotating shaft portion 105a of the power supply electrode 10a is transmitted through the power supply electrode 10a, and the conductive portion of the first conductive member 6a from the conductive portion 106a through the second conductive member 8a. 51, is transmitted from the conductive portion 51 to both the electrode power feeding portions 50 and 52 within the first conductive member 6a, and reaches the electrode portions 35a and 36a of the organic EL device 5. The current that has reached the electrode portions 35a and 36a is transmitted to the first electrode layer 21 and spreads in the first electrode layer 21 in a planar shape, and the function layer 22 emits light through the organic EL element 30, and the second electrode layer. 23. At this time, a voltage is applied to the functional layer 22 and the functional layer 22 emits light.

  As shown in FIG. 19B, the current reaching the second electrode layer 23 is transmitted to the electrode power feeding portions 50 and 52 of the first conductive member 6b, is transmitted through the first conductive member 6b, and reaches the conductive portion 51. 2 is transmitted to the conductive member 8b. The power is transmitted from the second conductive member 8b to the conductive portion 106b of the power supply electrode 10b, from the conductive portion 106b of the power supply electrode 10b through the power supply electrode 10b, and transmitted from the rotary shaft portion 105b to the bearing portion 93. The bearing portion 93 is transmitted through the conductive member 91 in the support portion 87 to reach an external power source.

Next, an application example of the organic EL module mounting structure 1 will be described.
The organic EL module mounting structure 1 shown in FIG. 1 is installed at a boundary portion between a ceiling 116 and a wall 117 of a living space. Specifically, in the vicinity of the corner formed by the ceiling 116 and the wall 117, the attachment portion 85 is fixed to the wall 117 so as to straddle the ceiling 116 and the attachment portion 85 as shown in FIG. 1. A reflection member 115 is laid. The reflection member 115 has an arc-shaped reflection surface, and the reflection surface has an arc shape centering on the rotation shaft portions 105 a and 105 b of the organic EL module 2. That is, all or a part of the reflecting surface has a constant distance from the rotation shaft portions 105a and 105b.
As used herein, “near the corner” means that the shortest distance from the corner where the ceiling 116 and the wall 117 intersect to the support portion 86 or the support portion 87 of the attachment device 3 is longer than the length of the long side of the organic EL module 2. Represents being close. It is preferable that the shortest distance from the corner portion where the ceiling 116 and the wall 117 intersect to the support portion 86 or the support portion 87 of the mounting device 3 is equal to or shorter than the length of the short side of the organic EL module 2. It is particularly preferable that the length is 2/3 or less of the side length.
Further, in the organic EL module mounting structure 1 shown in FIG. 1, a plurality of organic EL modules 2 are arranged in parallel for one mounting device 3. And the support part 86 or the support part 87 of one attachment apparatus 3 is located between the adjacent organic EL modules 2, and both the adjacent organic EL modules 2 are pivotally supported. The rotating shaft portions 105a and 105b of the adjacent organic EL modules 2 are arranged on the same straight line in the juxtaposed direction. Therefore, the space | interval between the organic EL modules 2 adjacent in the parallel arrangement direction can be narrowed.

Since the organic EL module 2 is rotatable relative to the attachment device 3, direct directing of the light emitting surface 31 of the organic EL module 2 toward the living space as shown in FIG. Functions as lighting. Moreover, by directing the light emitting surface 31 of the organic EL module 2 toward the ceiling 116 as shown in FIG. 20B, the reflecting surface of the reflecting member 115 reflects the irradiated light and transmits it to the living space side. That is, the organic EL module 2 functions as pseudo cove illumination by changing the position of the light emitting surface 31. In this state, the reflecting surface of the reflecting member 115 intersects the optical axis of the light.
By directing the light emitting surface 31 of the organic EL module 2 toward the wall 117 as shown in FIG. 20C, the reflecting surface of the reflecting member 115 reflects the irradiation light and transmits it to the living space side. That is, the organic EL module 2 also functions as pseudo cornice illumination by changing the position of the light emitting surface 31. In this state, the reflecting surface of the reflecting member 115 intersects the optical axis of the light.
As described above, since the organic EL module mounting structure 1 shown in FIG. 19 functions as at least three lights, it can flexibly cope with a change in the layout of the living space.

  Finally, each part constituting the organic EL device 5 will be described.

As the substrate 20, a substrate having translucency is adopted. For example, a flexible substrate or a plastic substrate is appropriately selected and used. A glass substrate or a film substrate is particularly preferable from the viewpoints of transparency and workability.
In the present embodiment, a glass substrate is employed as the substrate 20.
The thickness of the substrate 20 is 0.3 mm to 5 mm, and preferably 0.5 mm to 3 mm.
The area of the substrate 20 is a 4m ² from 25 cm ^2, preferably from 50 cm ² is 2m ^2, and particularly preferably from 100 cm ² is 2500 cm ^2.

  The organic EL element 30 is a laminate formed of at least a first electrode layer 21, a functional layer 22 (organic light emitting layer), and a second electrode layer 23.
