(First embodiment)
The light emitting module 1 according to the first embodiment of the present invention covers a rectangular flat light emitting panel 4 and the light emitting panel 4 so as to sandwich the light emitting panel 4 from both sides as shown in FIGS. A cover 2 and a main body 6 are provided. The light emitting module 1 is generally a rectangular flat plate corresponding to the shape of the light emitting panel 4. The light emitting module 1 has two-fold rotational symmetry with a perpendicular passing through the center of gravity as a rotation axis.

  As shown in FIG. 2, the light emitting panel 4 includes a transparent substrate 41, a light emitting unit 42 laminated on the upper surface of the transparent substrate 41, a heat stabilizing plate 43, a pair of electrode substrates 44, a wiring 45, and a power line. 46. The transparent substrate 41 has a rectangular flat plate shape, and is made of a transparent material such as glass, quartz, or a resin material. The transparent substrate 41 has a lower surface 411 that forms the main surface of the light emitting panel 4 and a side surface 412 that forms the side surface of the light emitting panel 4.

  The light emitting unit 42 has a rectangular flat plate shape having a smaller planar pattern than the transparent substrate 41 so as to correspond to the planar pattern of the transparent substrate 41. The light emitting unit 42 includes a pair of electrode films formed on both sides. Of the pair of electrode films of the light emitting section 42, at least the electrode film on the transparent substrate 41 side is made of a material having optical transparency and electrical conductivity. For example, a metal compound such as indium tin oxide (ITO) can be adopted. is there. The light emitting unit 42 includes an organic electroluminescence (EL) layer formed between a pair of electrode films.

  The organic EL layer of the light emitting unit 42 includes a plurality of layers made of an organic material such as a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, and an electron injection layer. The light emitting unit 42 emits light by recombination of holes and electrons in the light emitting layer of the organic EL layer when a voltage is applied using the pair of electrode films as an anode and a cathode. The light emitted from the light emitting unit 42 is emitted from the lower surface 411 and the side surface 412 of the transparent substrate 41. The dimension of the planar pattern of the light emitting unit 42 is, for example, about 80 × 80 mm.

  The heat stabilizing plate 43 is laminated on the entire upper surface of the light emitting unit 42, for example. The heat stabilizing plate 43 is made of a material having a higher thermal conductivity than the light emitting unit 42. The heat stabilizing plate 43 can reduce the variation and deterioration of the light of the light emitting part 42 due to Joule heat by making the heat distribution of the light emitting part 42 uniform during light emission.

  For example, the pair of electrode substrates 44 are disposed in the vicinity of two sides facing each other on the upper surface of the heat stabilizing plate 43. The electrode substrate 44 is electrically connected to the pair of electrode films of the light emitting unit 42. The wiring 45 is made of a metal material, and electrically connects the terminal of the electrode substrate 44 and the electrode film of the light emitting unit 42. The power lines 46 are electrically connected to the terminals of the pair of electrode substrates 44, respectively. The light emitting unit 42 is supplied with power from the power supply line 46 via the electrode substrate 44 and the wiring 45.

  The cover 2 is generally a rectangular flat plate and has a larger plane pattern than the light emitting panel 4 so as to correspond to the light emitting panel 4. The cover 2 is made of a transparent material such as glass, quartz, or a resin material. As the resin material forming the cover 2, for example, acrylic, polyester, polyethylene, nylon, or the like can be used.

  The cover 2 has an accommodating portion 21 that is a recess that opens on the upper surface side by being formed with a thickness lower than that of other places. The accommodating portion 21 includes an inner bottom surface 211 that faces the main surface (lower surface 411) of the light emitting panel 4, and an inner wall surface 212 that is perpendicular to the inner bottom surface 211 and faces the side surface (side surface 412) of the light emitting panel 4. Have. The accommodating part 21 accommodates the light emitting panel 4 in the interior surrounded by the inner bottom surface 211 and the inner wall surface 212. The light emitting panel 4 and the inner bottom surface 211 of the accommodating part 21 have, for example, the same plane pattern.

  The cover 2 has a frame portion 22 positioned around the housing portion 21 with the inner wall surface 212 of the housing portion 21 as an inner surface, and a bottom surface 20 that is parallel to the inner bottom surface 211 and has a larger area than the inner bottom surface 211. The bottom surface 20 is located below the accommodating portion 21 and the frame portion 22. As shown in FIG. 3, the frame portion 22 is formed so that the upper surface 23 forms an inclined surface formed such that the height decreases from the inner surface (inner wall surface 212) toward the outer surface 24. That is, in the cover 2, the height t <b> 3 of the outer side surface 24 is lower than the height t <b> 4 of the inner wall surface 212. The height t3 is, for example, about 1 mm to 4 mm. The size of the bottom surface 20 is, for example, about 110 × 110 mm.

  Since the light emitting panel 4 and the inner bottom surface 211 correspond to a planar pattern, the light emitted from the light emitting panel 4 reduces unnecessary diffusion as the side surface of the light emitting panel 4 and the inner wall surface 212 come closer to each other. The light is efficiently emitted from the outer surface 24 and the bottom surface 20 of the cover 2 to the outside. Since the electrode substrate 44 and the like are formed on the light emitting panel 4, there is no member that blocks light between the light emitting panel 4 and the outer surface 24, and light can be efficiently emitted to the outside.

  The main body 6 has a generally rectangular plate shape. The main body 6 is made of an opaque material such as a resin material or metal. The main body 6 is formed such that the height of the upper surface 63 decreases as it goes from the central portion toward the peripheral portion. That is, as shown in FIG. 2, in the main body 6, the height t1 of the peripheral portion is lower than the height t2 of the central portion. For example, the upper surface 63 is gently curved so as to bulge upward. The height from the bottom surface 20 of the cover 2 to the center of the upper surface 63 of the main body 6 is, for example, about 8 to 10 mm.

  The main body 6 is located within a region overlapping the light emitting panel 4 in plan view. In the example shown in FIGS. 1-3, the main body 6 and the light emission panel 4 have the same plane pattern. The main body 6 has a through-hole 60 that penetrates from the upper surface 63 to the lower surface 61 in the center and into which the power line 46 of the light-emitting panel 4 is inserted.

  The light emitting module 1 further includes a polarizing plate 3, an adhesive material 5, and a support 7. The polarizing plate 3 is a rectangular flat plate having the same plane pattern as the main surface (lower surface 411) of the light emitting panel 4, for example. The polarizing plate 3 is disposed in parallel with the light emitting panel 4 between the main surface of the light emitting panel 4 and the inner bottom surface 211 of the housing portion 21. The polarizing plate 3 polarizes the light emitted from the light emitting panel 4 and emits it from the bottom surface 20 of the cover 2 and reduces reflection of light from the outside. Between the main surface of the light emitting panel 4 and the inner bottom surface 211 of the accommodating part 21, you may make it provide the optical panel which has functions, such as condensing and a diffused light, besides polarized light.

  The adhesive 5 bonds the upper surface of the light emitting panel 4 and the lower surface of the main body 6. For example, the adhesive 5 is positioned between the pair of electrode substrates 44 of the light emitting panel 4 and is formed in a rectangular shape in a region excluding the through hole 60 of the main body 6. The light-emitting panel 4 is bonded to the main body 6 by the adhesive 5 so that damage due to dropping or the like is reduced, and even when the light-emitting panel 4 is damaged, scattering of fragments can be reduced.

  The support column 7 has a cylindrical shape having a through hole 70. The support column 7 is connected to the central portion of the upper surface 63 of the main body 6 at one end side, thereby supporting the main body 6 at the center of gravity of the light emitting module 1. The through hole 70 of the column 7 is connected to the through hole 60 of the main body 6, and the power line 46 of the light emitting panel 4 is inserted therein.

  The main body 6 is disposed so as to close the upper end of the housing portion 21 in a state where the polarizing plate 3 and the light emitting panel 4 are housed inside the housing portion 21. The main body 6 is installed on the cover 2 so that the upper surface 63 and the upper surface 23 of the frame portion 22 are continuous.

  The light emitting module 1 includes a plurality of hook portions 65 that are fixed, for example, in the vicinity of two opposing sides of the peripheral portion of the main body 6 so as to be lower than the upper surface 63 of the main body 6. The hook portions 65 project horizontally from the main body 6 in the outer direction. The cover 2 has a plurality of hook receiving portions 25 which are concave portions formed on the inner wall surface 212 at positions corresponding to the plurality of hook portions 65, respectively. The hook part 65 and the hook receiving part 25 corresponding to each other function as a fixing part (25, 65) for fixing the main body 6 and the cover 2 to each other.

  According to the light emitting module 1 according to the first embodiment, since the bottom surface 20 is flat and the height t1 of the peripheral portion of the main body 6 is formed lower than the height t2 of the central portion, it looks thinner than the actual thickness, Designability can be improved and warpage due to heat or the like can be reduced. Moreover, since the cover 2 is formed so that the light emitted from the light emitting panel 4 is emitted from the bottom surface 20 and the outer surface 24, the light can be emitted with high efficiency. Moreover, since the edge part of the cover 2 looks shining, the design can be further improved.

  Moreover, according to the light emitting module 1 which concerns on 1st Embodiment, since the height t3 of the outer surface 24 of the cover 2 is formed so that it may become lower than the height t4 of the inner wall surface 212, the design property can further be improved.

  Moreover, in 2nd Embodiment already described, a lighting system is provided with the illuminating device 8c, and among the light emitting modules 1a-1h, the light emitting module 1h located in the wall surface W side irradiates the upper part of the wall surface W. Alternatively, the angle may be adjusted.

  Further, in the first to third embodiments already described, the support column 7 that supports the light emitting module 1 may be adjustable in length and irradiation direction of the light emitting module 1. Thereby, for example, as shown in FIG. 10, even after the plurality of light emitting modules 1 are arranged in a single plane, the height and angle of each light emitting module 1 can be adjusted, and various spaces can be adjusted. Can be expressed. For example, as shown in FIGS. 11A and 11B, each light emitting module 1 is arranged so that the height and the angle change as it approaches the corner of the room, and thus varies depending on the viewing position. Can give an impression. In addition, the light emitting module 1 changes in height in one direction as shown in FIGS. 12 (a) and 12 (b), or becomes higher as it goes from the peripheral edge of the room toward the center as shown in FIG. The height and angle may be changed.

  In the example shown in FIG.12 and FIG.13, the length of the support | pillar 7 is adjusted so that the light emitting module 1 may not touch a person. The strut 7 may be longer than other places in places where there is little traffic such as in a counter on the wall side. In the example shown in FIGS. 10 to 13, the support column 7 is directly supported by the ceiling surface C, and the ceiling surface C is a mirror surface so that the back side of the light emitting module 1 is clearly reflected on the ceiling surface. Good.

  In addition to the above, it goes without saying that the present invention includes various embodiments that are not described here, such as configurations in which the first to third embodiments are mutually applied. Therefore, the technical scope of the present invention is defined only by the invention specifying matters according to the scope of claims reasonable from the above description.
