  By the way, when the organic EL element built in the organic EL panel is driven for a certain period, there is a problem that light emission characteristics such as light emission luminance, light emission efficiency, light emission uniformity and the like are significantly deteriorated as compared with the initial case. As a cause of such deterioration of the light emission characteristics, there can be mentioned modification and decomposition of organic substances. This modification and decomposition of the organic matter is triggered by the fact that the driving environment is at a high temperature. In addition, when the temperature is locally increased due to heat generation during driving, compressive stress is generated at the interface of the structure due to the difference in the coefficient of thermal expansion of each component, and the structure may be partially peeled off. It also causes mechanical degradation.

That is, the organic EL panel is not easily thermally deteriorated.

The present invention provides an organic EL panel that is attached to one surface of a plate-like body that forms any one of a ceiling, a wall surface, and a floor surface, and includes a base portion that is attached to the other surface of the plate-like body, and a connector portion.

  On the other hand, as shown in FIG. 6, the lower skeleton portion 36 (on the ceiling board 2 side) located on the lower surface side of the skeleton portion 27 is formed of a material having low thermal conductivity such as plastic. Therefore, the mounting part 30 can be shielded from heat sources such as the organic EL panel 5.

Specifically, it arrange | positions so that it may contact | connect directly on the sealing layer 216 (refer FIG. 15) of the organic EL apparatus 201 mentioned later.
Since the soaking sheet 211 covers the entire area of the light emitting region 50, in the light emitting region 50, the variation of the light emitting portion due to the in-plane temperature distribution can be suppressed, and the uniformity of the light emitting portion can be improved.

Further, the soaking sheet 211 extends from the light emitting region 50 to the power feeding unit 12. That is, the soaking sheet 211 covers almost the entire area of the organic EL panel 5. A protective film 226 covers the soaking sheet 211.
In addition, the organic EL panel 5 has a heat transfer region 20 in which a part of the heat equalizing sheet 211 is exposed from the protective film 226 in the power feeding unit 12 as illustrated in FIG. 8. Therefore, it is possible to efficiently transfer heat generated by the light emission of the organic EL panel 5 to the attachment device 3, and it is possible to prevent the temperature of the organic EL panel 5 from rising excessively.

That is, the interval adjusting member 21 can adjust the attachment position 3 of the organic EL panel 5 fitted to the connector portion 6 with respect to the ceiling plate 2 in the attachment posture.

  Then, the positional relationship of each member in each attitude | position of the attachment structure 1 of an organic electroluminescent panel is demonstrated.

First, for convenience of explanation, the illumination posture will be described.
The organic EL panel 5 is fitted to the connector portion 6 as shown in FIG. 10 and is fixed to the ceiling plate 2 in a lateral position via the connector portion 6. That is, the surface of the organic EL panel 5 faces the top-and-bottom direction.
The organic EL panel 5 is supported in a cantilever manner with the connector portion 6 as a fulcrum. That is, the organic EL panel 5 is indirectly supported by the ceiling plate 2.
Focusing on the connector part 6, the mounting opening of the angle changing means 60 inside the panel recess 8 of the connector part 6 faces the parallel direction with respect to the ceiling plate 2. That is, in the organic EL panel, the free end side is not located on the lower side in the vertical direction with respect to the fixed end. In other words, the mounting opening of the angle changing means 60 inside the panel recess 8 of the connector portion 6 is not inclined with respect to the ceiling plate 2.

A power feeding portion 12 that is a part of the organic EL panel 5 is fitted into the panel recess 8 of the connector portion 6. The power supply terminal 16 in the contact surface 17 is in contact with the electrode 33 of the organic EL panel 5.
Moreover, the exposed part (the end surface of the recessed part 8 for panels) to the living space 100 of the connector part 6 and the wall board 4 are flush | planar like FIG. That is, most of the connector part 6 is located on the back side of the ceiling plate 2 and the wall plate 4 and is invisible or difficult to see from the user.

  The distance H2 between the lower surface of the ceiling plate 2 and the upper surface of the organic EL panel 5 is not particularly limited, but may be 0 mm or more and 3 cm or less from the viewpoint of appearance, possibility of installation in a narrow place, and ease of replacement work. Preferably, it is 0 mm or more and 1 cm or less, more preferably 0 mm or more and 5 mm or less, and most preferably substantially in contact. Here, “substantially touching” means not only the case where the entire organic EL panel 5 is in contact with the ceiling plate 2 but also the case where only a part of the organic EL panel 5 is in contact with the ceiling plate 2. Including.

The base portion 7 is located at a position facing the organic EL panel 5 with the ceiling plate 2 interposed therebetween as shown in FIG.
Between the upper surface of the ceiling board 2 and the lower surface of the base portion 7, one or a plurality of interval adjusting members 21 are interposed. That is, the ceiling board 2 and the base part 7 are arranged at a predetermined interval. In other words, a heat insulating space 37 (air layer) is formed between the ceiling plate 2 and the base portion 7. Since the heat insulating space 37 is formed, the heat transmitted to the base portion 7 is transmitted to the ceiling plate 2 and the ceiling plate 2 can be prevented from becoming high temperature. Further, it is possible to prevent the heat transmitted to the base portion 7 from flowing back to the organic EL panel 5 in a state where the driving of the organic EL panel 5 is stopped.
In the present embodiment, two spacing adjusting members 21 are provided at the front end (side facing the connector section 6) and the rear end (connector section 6 side) end of the base section 7. .

  The lower surface of the interval adjusting member 21 (or the lower surface of the base portion 7) and the upper surface of the ceiling plate 2 are attached with a double-sided adhesive sheet. Therefore, it can be easily attached to the ceiling board 2.

Next, the exchange posture will be described.
As shown in FIG. 11, the organic EL panel 5 is fitted with the connector portion 6 in an inclined posture inclined at a predetermined angle with respect to a horizontal plane. Specifically, the angle of the organic EL panel 5 with respect to the horizontal plane is greater than 0 degree and 45 degrees or less, preferably 5 degrees or more and 30 degrees or less, and preferably 10 degrees or more and 20 degrees or less. Is particularly preferred. Further, when paying attention to the connector portion 6, the opening for attaching the organic EL panel 5 of the angle changing means 60 of the panel recess 8 is inclined at a predetermined angle with respect to the horizontal plane and faces the living space 100 side. That is, when the organic EL panel 5 is removed, the user can see the opening. Therefore, it is easy to replace the organic EL panel 5.

Next, the flow of current and heat in the organic EL panel mounting structure 1 of the present embodiment will be described.
First, the flow of current will be described. The current supplied from the commercial power source to the mounting unit 30 is supplied to the organic EL panel 5 through the base unit 7 and the connector unit 6 as shown in FIG. That is, when power is supplied from a commercial power supply, a voltage can be applied to the organic EL panel 5.
Specifically, the current supplied from the commercial power source to the mounting portion 30 is transmitted to the energizing convex portion 31 (see FIG. 6) through the base energizing member 57 in the base portion 7. The current transmitted to the energizing convex portion 31 is transmitted from the energizing convex portion 31 of the base portion 7 to the energizing concave portion 25 (see FIG. 5) of the connector portion 6, through the connector energizing member 55 in the connector portion 6, It is transmitted to the power supply terminal 16. The current transmitted to the power supply terminal 16 is transmitted to the electrode 33 of the organic EL panel 5 and the organic EL element 220 in the organic EL device 201 emits light.

Subsequently, the flow of heat will be described. When the organic EL panel 5 is supplied with power from the commercial power source to the electrode 33 as described above, the organic EL element 220 in the organic EL device 201 emits light, and heat is generated. The heat generated at this time reaches the heat radiating portion 23 via the connector portion 6 and the upper skeleton portion 35 of the base portion 7 as shown in FIG.
Specifically, the heat generated from the organic EL element 220 is transmitted to the soaking sheet 211, and is transmitted from the soaking sheet 211 to the heat transfer region 20 of the power feeding unit 12. Thereafter, the heat is transmitted from the organic EL panel 5 to the heat transfer terminal 18 of the connector portion 6, is transmitted through the connector heat transfer member 56 in the connector portion 6, and is transmitted to the heat transfer recess 26 (see FIG. 5). Then, the heat transferred to the heat transfer recess 26 is transferred from the heat transfer recess 26 to the heat transfer convex portion 32 (see FIG. 6) of the base portion 7 and passes through the base heat transfer member 58 in the base portion 7. Then, heat is radiated to the outside from the upper skeleton 35 of the base 7 and the fins of the heat radiating portion 23.

  According to the present invention, since heat generated in the organic EL element 220 can be released to the outside during energization, it is difficult to deteriorate.

Then, it demonstrates along the general installation procedure of the attachment structure 1 of an organic electroluminescent panel.
First, the connector part 6 and the ceiling board 2 to be used corresponding to the power feeding part 12 of the organic EL panel 5 to be used are selected.

Moreover, the ceiling board 2 shall be selectable from various members according to the use site | part, design, and intensity | strength.
Next, as shown in FIG. 14, the connector part 6 and the base part 7 are fitted and integrated.
Then, when the base part 7 is installed above the ceiling board 2, the thickness of the space | interval adjustment member 21 is selected so that the lower surface of the ceiling board 2 may contact | connect the upper surface (non-light-emitting surface) of the organic EL panel 5 substantially. A plurality of interval adjusting members 21 are placed on the ceiling board 2. The space | interval adjustment member 21 is adhere | attached on the ceiling board 2 with a double-sided adhesive sheet as needed.
The mounting portion 30 is formed by connecting the base portion 7 and the mounting parts installed on the upper surface of the base portion 7 with lead wires or the like, and unnecessary lead wires are cut and deleted.
And the connector part 6 is mounted in the upper end surface of the wall board 4, and it fixes with a well-known fastening element so that only the opening 11 of the connector part 6 may be visually recognized from the living space side.

  The installation or replacement of the organic EL panel 5 is performed by a contractor or general customer by fitting the power feeding unit 12 of the organic EL panel 5 to the connector unit 6.

Next, the layer configuration of the organic EL device 201 built in the organic EL panel 5 will be described.
As shown in FIG. 15, the organic EL device 201 includes an organic EL element 220 on a substrate 202 (base material).
The organic EL element 220 is formed by laminating a first electrode layer 203, a functional layer 205 (organic light emitting layer), and a second electrode layer 206 in order from the substrate 202 side.
The organic EL device 201 includes a sealing layer 216 that covers and seals all or part of the organic EL element 220 from above (the side facing the substrate 202). Therefore, it is possible to prevent moisture from entering the organic EL element 220.

As shown in FIG. 15, the sealing layer 216 is formed by two layers of a deposition layer 207 and a coating layer 208 in order from the second electrode layer 206 side.
A soaking sheet 211 is placed on the coating layer 208, and the soaking sheet 211 is fixed on the coating layer 208 by an adhesive 210.

A current supplied from the outside flows from the first electrode layer 203 a side to the second electrode layer 206 a side through the functional layer 205 a, but a part of the second electrode layer 206 a is an entrance portion in the functional layer separation groove 222. A current flows through the first electrode layer 203b of the adjacent unit EL element 215b through the first unit EL element 215a through contact with the adjacent first electrode layer 203b through 212a. As described above, in the organic EL device 201, all the unit EL elements 215 are electrically connected in series, and all the unit EL elements 215 emit light. At this time, since a part of the functional layer 205a enters the bottom of the first electrode layer separation groove 221, no current flows from the first electrode layer 203b to the first electrode layer 203a.
In addition, the site | part (functional layer 205) which the unit EL element 215 light-emits becomes a light emission site | part, and the area | region including the non-light-emission site | part among these some light emission site | parts becomes the above-mentioned light emission area | region 50.
