Description

  The present invention relates to a laminated body with a light emitting function capable of causing light of a desired lighting pattern such as letters and designs to float on a wooden surface layer.

  The doors can be installed at the entrance of the building to block the inside and outside of the building, and also function as crime prevention, rain prevention, and airtightness, such as partitioning the interior space. In addition, other members may be mounted on the door surface for use. For example, by hanging a writable board such as a message board on the door, information on the other side of the door can be transmitted. Specifically, by posting a “meeting” tag, it is possible to suggest a room condition to a person who wants to open the door in advance. Or you can instruct the visitor to act by placing a tag that says “Don't wake up” on the doorknob.

In this case, the door is a support for mounting the message board, and the door itself does not have an information transmission function. That is, it is common to prepare the door function and the information transmission function separately, and in this case, there are the following problems.
1. The number of members increases.
2. 2. It is difficult to recognize messages in the dark. When there is no message, posting an empty board will damage the exterior of the door. Alternatively, a place for removing the board itself and storing it is required.
4). In order to be able to be used repeatedly, the message board is mainly written on a plastic white board using a water-based felt pen, and the contents of the message can be changed by wiping ink with paper or cloth as necessary. In other words, the ink is easily erased, and part of the ink is unexpectedly erased, such as contact of clothes by opening and closing the door, making it difficult to recognize characters. On the other hand, when an oil pen is used, undesired erasure is avoided, but it cannot be used repeatedly and is inconvenient. In other words, the degree of freedom in changing the display contents and the maintenance of stable display cannot be achieved at the same time.

  In order to solve the above-mentioned problems, the present inventor first developed a door with a pattern light emission function in which an information transmission function is added to the door (Patent Document 1). This door is shown in FIG. The door 100 with a pattern light emitting function in FIG. 10 is formed by laminating a projecting plate 101, a PET resin sheet 102, a fiber board 103, a warpage preventing sheet 104, a light emitting device 105, and a back plate 106 in this order from the door surface side. The fiber board 103 includes an opening 103a punched into a shape that is desired to be displayed on the surface of the protruding plate 101. The light emitting device 105 is equipped with an LED light source 105a. When this LED light source 105a is turned on, the emitted light passes through the opening 103a of the fiber board 103 and proceeds to the protruding plate 101 side, and further passes through the protruding plate 101, thereby forming a pattern along the opening shape of the opening 103a. The surface of the protruding plate 101 can be raised. Further, since the LED light source 105a and the opening 103a are covered with the protruding plate 101, they are not exposed. That is, when the LED light source 105a is turned off, a pattern does not appear and the wood texture of a normal door is not impaired. Thus, the door with a pattern light emission function which solved the above-mentioned problems 1 to 3 is realized.

  However, if it is a form of FIG. 10, the lighting pattern which appears will be fixed with the process shape of the opening part 103a, and a lighting pattern cannot be changed. Therefore, as a result of earnest research, the inventor has developed a form in which the appearance lighting pattern can be freely changed by controlling the shape of the lighting pattern not on the opening but on the light source side. That is, a point light source assembly in which light sources are arranged in parallel in a dot matrix is used, and on / off of each point light source is controlled. And the shape of a lighting pattern is comprised by combining the light emission area | region of the lit point light source. That is, since various light emission areas can be realized by controlling the point light source, the lighting pattern by adding the light emission areas can be freely expressed, and the display contents can be easily changed. Of course, since the lighting pattern is composed of light, the display content is not unintentionally erased even when it comes into contact with the display unit, and stable display can be achieved. That is, the form which improves the said 4 problems was developed.

  However, since a lighting pattern such as a desired character or picture is expressed by a set of point light sources, a point light source arranged in a dot matrix has a small distance between adjacent point light sources. As a result, there is a possibility that the emitted light of the point light source that is lit may enter a light source region that is not lit, which irradiates an undesired region. Then, the edge of the lighting pattern that appears is blurred and the whole image is blurred. For this reason, if the directivity of the transmitted light is increased so as to limit the leakage light of the point light source, the difference in illuminance between the region directly above the point light source and the other region becomes large. As a result, the viewing angle becomes narrow and it becomes difficult to recognize the display content from an oblique direction. That is, the pursuit of directivity and diffusivity is in a relative relationship, and there is a problem that it is difficult to satisfy both.

In addition, since the point light source is configured in a dot matrix, the number of point light sources is increased. As a result, the power consumption and the amount of generated heat increase, and there is a risk that deterioration such as baking, discoloration, and deformation of a member close to the light source is likely to occur.
JP 2007-271862 A

  The present invention has been made to solve the conventional problems. The main object of the present invention is a laminated body with a light emitting function in which a lighting pattern of light of a desired shape emerges on a wooden surface layer and notifies a significant sign to an unspecified number of people. An object of the present invention is to provide a laminated body with a light emitting function capable of changing to a light emitting pattern capable of appearing a lighting pattern having high visibility.

  In order to achieve the above object, a first laminate with a light emitting function of the present invention is a laminate with a light emitting function capable of displaying a desired lighting pattern on the surface of a wood layer, and has an opening at least partially. A sheet layer 14 formed with 14a, a wood layer 11 covering the opening 14a on the first surface side of the sheet layer 14, and a second surface side facing the first surface side of the sheet layer 14 A light source 15 in which a plurality of light emitting elements 21 that can irradiate the opening 14a are arranged in a dot matrix, and a lighting control means 25 that can independently control lighting of the light emitting elements 21 of the light source 15, have. The light emitted from the light source 15 travels through the opening 14 a and is further transmitted through the wood layer 11. The lighting that is displayed on the surface of the wood layer 11 by blinking each light emitting element 21 of the light source 15. The pattern is configured to be displayed as a moving image.

  The second laminate with a light emitting function of the present invention is further characterized in that a paper layer 12 having a light transmittance of 30% to 70% is interposed between the wood layer 11 and the opening 14a. To do.

  Moreover, the 3rd laminated body with a light emission function of this invention has the reinforcement layer 13 which obstruct | occludes the opening part 14a further, and the separation distance w from the light emitting element 21 to the reinforcement layer 13 shall be 0 mm-2 mm. It is characterized by.

  Moreover, the 4th laminated body with a light emission function of this invention is characterized by the light emitting element 21 of the light source 15 being comprised with the light emitting diode.

  The fifth laminate with a light emitting function of the present invention further includes a frame 18 that surrounds the periphery of the wood layer 11, and the frame 18 is made of aluminum.

  Moreover, the 6th laminated body with a light emission function of this invention is characterized by a laminated body being a door.

  The laminate with a light emitting function of the present invention has a unique structure in which the wood layer is arranged in the traveling direction of the light source, and when the lighting pattern is not displayed, the texture of the wood layer laminated on the surface itself is enjoyed. it can. And lighting patterns, such as a character and a design, can appear only at a desired timing. That is, when the light source is not energized, the wood layer covers the opening and the light source, and the opening and the light source are not exposed on the surface side. Therefore, even the presence of a light emitter cannot be predicted. On the other hand, when the energization is energized, the lighting pattern emerges so that the grain of the wood layer 11 stands out. The lighting pattern appearing on the surface of the wood layer can be freely and easily changed, and has high visibility.

  In particular, by setting the distance between the light emitting element and the reinforcing layer to be 0 mm to 2 mm, in the traveling direction of the emitted light of the light source, the directivity is high up to the vicinity of the surface of the wood layer, and the diffusibility can be enhanced thereafter. . That is, the lighting pattern that appears is a clear image with a clear edge near the surface of the wood layer, and in addition, the visibility of the lighting pattern can be enhanced even from an oblique direction of the wood layer due to the subsequent diffusion effect. That is, it is possible to provide a light source having an excellent balance between directivity and diffusibility with respect to the surface of the wood layer displaying the lighting pattern.

  In addition, by enabling the light source to blink, the thermal effect due to the arrangement of the wood layer and the light source within the separation distance can be reduced, and the durability of the member can be improved. That is, by blinking the light source, the power consumption and heat generation of the light source can be reduced as compared with continuous lighting. As a result, heat generation from the light source is conducted to the wood layer and other members, and the member can be prevented from being discolored or deformed by baking. In addition, the battery can be driven by a battery or the like by reducing the power consumption. Furthermore, the lighting pattern expression method can be variously changed by blinking display, and various displays such as scrolling of figures such as letters, numbers, symbols, logos, and moving pictures can be realized.

  Further, by interposing a paper layer having a light transmittance of 30 to 70% between the wood layer and the opening, the light becomes substantially uniform due to the diffusibility of the light source, and the lighting pattern appearing on the surface of the wood layer The color unevenness can be reduced and the appearance light can be visually recognized from multiple directions by the diffusion effect. Furthermore, since it can prevent that an opening part is transparent from the surface side of a woody layer, the situation where the opening part from the surface side can be seen through can be avoided. In addition, the wood layer and the reinforcing layer have different surface layers, and by interposing the paper layer between them, the adhesion between the paper layer and each member is increased. Adhesion with the layer can be improved.

  Furthermore, the strength in the opening can be improved by having the reinforcing layer that closes the opening. Further, the warping of the member can be prevented by narrowing the reinforcing layer.

  Further, by forming the light source with a light emitting diode, light emission with a small size, high power efficiency, and vivid color can be realized. In addition, there is no fear of running out of the ball, and the initial drive characteristics are excellent, and it has a strong effect on vibration and repeated on / off lighting.

  Moreover, since the frame body surrounding the wood layer is provided and the frame body is made of aluminum, the frame body can have a high thermal conductivity. Therefore, the heat radiation from the light source can be improved and the durability of the member can be improved. Furthermore, a laminated body can be reinforced by surrounding the periphery of a member with a frame, and a tough structure can be obtained while suppressing an increase in the overall weight.

  In addition, lighting of the plurality of light emitting elements can be independently controlled by the lighting control means, and light emission characteristics such as luminance and wavelength in the light emitted from the light emitting elements, or blinking timing can be easily controlled. As a result, it is possible to freely change the lighting pattern, color, and appearance form of characters and figures displayed on the surface of the wood layer.

  Furthermore, by using the laminated body with a light emitting function as a door, it is possible to display a lighting pattern on the surface layer of the door in a role as a normal door such as blocking the outside and the inside. That is, significant information can be made public by adding a function as an information transmission device to the door.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiment described below exemplifies a laminated body with a light emitting function for embodying the technical idea of the present invention, and the present invention specifies the laminated body with a light emitting function as follows. do not do. Further, in this specification, in order to facilitate understanding of the scope of claims, numbers corresponding to the members shown in the embodiments are indicated in the “claims” and “means for solving problems” sections. It is appended to the members shown. However, the members shown in the claims are not limited to the members in the embodiments. In particular, the dimensions, materials, shapes, relative arrangements, and the like of the component parts described in the embodiments are not intended to limit the scope of the present invention unless otherwise specified, and are merely explanations. It is just an example. Note that the size, positional relationship, and the like of the members shown in each drawing may be exaggerated for clarity of explanation. Furthermore, in the following description, the same name and symbol indicate the same or the same members, and detailed description thereof will be omitted as appropriate. Furthermore, each element constituting the present invention may be configured such that a plurality of elements are constituted by the same member and the plurality of elements are shared by one member, and conversely, the function of one member is constituted by a plurality of members. It can also be realized by sharing. Further, in the present invention, the term “door” is used to mean not only a door but also a door frame or its vicinity. In addition, the term “above” on a layer or the like is not necessarily limited to the case where it is formed in contact with the upper surface, but includes the case where it is formed on an upper side with a space between them. It is used in the meaning of including the case where it exists.

  An exploded perspective view of the laminate with a light emitting function according to Example 1 is shown in FIG. This laminated body 1 with a light emitting function includes a surface of a wood layer 11 on the front side of FIG. 1, and a paper layer 12 having substantially the same outer shape as the wood layer 11 on the back side of the wood layer 11 (back direction in FIG. 1), The reinforcing layer 13, the sheet layer 14, and the support layer 16 are laminated in order and substantially in parallel.

  The sheet layer 14 includes an opening 14a penetrating in the thickness direction, the wood layer 11 covers the front side of the opening 14a, and a plurality of dots arranged in a dot matrix on the back side of the opening 14a. The light source 15 comprised with the light emitting element of is provided. The light source 15 is fixed on the support layer 16 and disposed in a region corresponding to the opening 14a of the sheet layer 14, and further configured to irradiate the opening 14a. Each light emitting element is electrically connected to an external power source via a lighting control means so as to be blinkable. When energized, the light emitted from the light source 15 travels forward and passes through the opening 14a to pass through the wood layer 11. Transparent.

  Moreover, in Example 1, although a door is mentioned as an example of the laminated body with a light emission function as shown in FIG. 1, a laminated body with a light emission function is not limited to a door, plate-like members, such as a panel and a signboard, a floor, a ceiling It can be used for various members having a wood layer such as a partition material such as a partition or a partition.

  Further, FIG. 2 is a plan view of a door which is an example of the laminated body 1 with a light emitting function. As shown in FIG. 2A, the door 1 looks like a normal door having a wood texture of the wood layer 11 when the light source 15 is turned off, and the light source 15 is not exposed. On the other hand, when the light source 15 is energized, the emitted light emitted from the lit light source 15 travels to the wood layer 11 side, and further passes through the wood layer 11 and, as shown in FIG. A lighting pattern having the shape of the lighting area appears to appear on the surface of the door 1. Each member will be described individually below.

(Woody layer)
1 and 2, a veneer is used as the wood layer 11. A veneer is a thin plate made by cutting a beautiful material such as wood grain along the plate surface. Or you may use the decorative board finished by stretching this thin board on the surface. The thickness of the wood layer 11 is not particularly limited as long as the light emitted from the light source can be transmitted, but a thickness of 0.1 to 0.3 mm is preferably used. This is because an appropriate amount of light emitted from the light source 15 is transmitted and it becomes easy to visually recognize the lighting pattern that appears. In Example 1, a 0.2 mm projecting plate was used. The wood layer 11 preferably has a small difference in color tone of the grain. Thereby, when the light source light is irradiated, unevenness of light displayed on the wood layer 11 can be avoided.

  Moreover, you may process the surface of the woody layer 11 variously. For example, it is possible to enhance the design effect by, for example, increasing the glossiness by plating a metal or glass and applying a mirror finish to give a high-class feeling. Or you may add various decorations, such as a sculpture and an inlay.

(Paper layer)
The paper layer 12 may be a planar paper having a fiber structure such as shoji paper or Japanese paper, or a synthetic paper that is not limited to plant fibers but is mainly made of a synthetic resin such as a chemical fiber or a film. In particular, Japanese paper is intertwined with long fibers, so that even if folded or pulled, the intertwining cannot be easily released, and the fibers do not come out, so it is durable even when thin, and has excellent durability. Further, finer fibers are preferable because uniform light emission with less unevenness can be obtained. On the other hand, the synthetic paper can enjoy features such as moisture resistance and weather resistance. Further, a processed paper obtained by coating the surface of the paper with a protective film such as a resin, a plastic film, an aluminum foil, or another paper material, and laminating it by heating and pressing may be used. As a result, a multi-layered paper layer 12 to which various functions such as strength and resistance are further improved can be obtained. The paper layer 12 is preferably reinforced shoji paper. In the example of FIG. 1, Waron (registered trademark) or New Tough Top manufactured by Waron Co., Ltd. was used. Waron is a product made by laminating the front and back surfaces of natural Japanese paper with vinyl chloride resin. However, it is not limited to this processing form, for example, you may utilize what laminated | stacked resin only on the single side | surface of Japanese paper.

  In this way, by pressing the resin on the paper surface in the paper layer 12, the heat resistance is increased and the warpage of the paper layer 12 itself can be prevented. Thereby, the paper layer 12 can be affixed efficiently. Specifically, when the paper layer 12 is affixed to the wood layer 11 or the reinforcing layer 13, a part of the thin paper is folded, air enters the adhesive surface with the attached member, or the paper layer 12 is wrinkled. This eliminates the problem that the paper layer 12 cannot be applied uniformly. That is, the paper layer 12 can be prevented from unwinding and easy to handle, so that the paper layer 12 and the wood layer 11 or the reinforcing layer 13 can be bonded substantially uniformly and tightly. As a result, the door is firmly stabilized and light unevenness due to wrinkle unevenness of the paper layer 12 can be avoided.

  Further, since the paper layer 12 has a light diffusing action, the viewing angle of the lighting pattern can be expanded by appropriately reducing the directivity of the light source. Thereby, the lighting pattern can be visually recognized from multiple directions of the door 1. The paper layer 12 serves as a filter that equalizes the amount of light passing from the light source. Thereby, the nonuniformity of the lighting pattern which appears in the door 1 can be reduced extremely. Furthermore, it is possible to prevent the shadow of the opening 14a located on the back side of the paper layer 12 from appearing on the surface of the door due to reflection from the light from the surface side of the door 1. This effect is particularly preferable for the white paper layer 12. Moreover, it can avoid that the shadow of the sheet layer 14 resulting from the thickness of the sheet layer 14 is projected on the surface of a door, and as a result, the nonuniformity of the light which appears on the surface of a door can be suppressed. Similarly, the arrangement pattern of light emitting elements such as LEDs housed in the opening 14a can be prevented from floating on the surface of the door. That is, it is possible to avoid the appearance of the non-lighted LED from being projected on the surface side of the door by the light emission of the lit LED, and to clarify the illuminance difference between the lighted area and the non-lighted area, and to appear on the door The visibility of the lighting pattern can be improved.

  The paper layer 12 is preferably made of paper having a light transmittance in the range of 30 to 70%. If the transmittance exceeds 70%, the diffusibility of the emitted light from the light source side is weakened, the viewing angle is reduced, and the shape of the opening 14a and the light source 15 is transmitted from the surface side of the door 1, which is inappropriate. . Moreover, if the transmittance is less than 30%, the visibility of the lighting pattern that appears is extremely reduced, which is not preferable. Therefore, if the light transmittance is within the above range, it is preferable that the amount of light transmitted through the paper layer 12 in both directions is well balanced. The paper layer 12 is, for example, 0.1 to 0.2 mm. When the paper layer 12 is too thin, the permeability is excessively increased due to the absorption of the adhesive, and an unintended member is projected onto the surface of the door. On the other hand, if the paper layer 12 is too thick, the light transmittance is deteriorated and it is difficult to recognize the lighting pattern. Therefore, it is preferable to be within the above range.

  The paper layer 12 is preferably plain white and contains fine fibers. This is because the light can be blocked by the fibers or the uneven transmission amount can be avoided and the transmission amount can be made uniform. As a result, it is possible to prevent the fibers from blurring and being projected when transmitted through the light source, that is, it is preferable to be an appearance light with a high decorative effect in which the grain of the protruding plate in the appearing lighting pattern area is sufficiently exposed.

  On the other hand, in the door 1, the dimensions of each member may change due to temperature changes and humidity changes in the installation environment, or warping of each member may occur. In particular, during production, the moisture content increases due to the application of an adhesive, decreases with the press for adhesion, and during use, the moisture content in the door changes due to the heat generated from the LED light source when the LED is lit. Is in an environment where it is likely to occur. As a result, the dimensional change accompanying the moisture content change of the several material which comprises a door differs, and generation | occurrence | production of curvature arises. The paper layer 12 has an effect of preventing such warpage of each member. Accordingly, the paper layer 12 has substantially the same outer shape as the wood layer 11, the reinforcing layer 13, and the sheet layer 14, and covering almost the entire surface of these members can more effectively prevent the warpage of each member. Furthermore, the blotting pattern resulting from the application | coating nonuniformity by an adhesive agent can be erase | eliminated by sucking in the excess adhesive agent apply | coated to the layer which touches.

  Further, as shown in FIG. 1, the front and back surfaces of the paper layer 12 are bonded to each other by a wood layer 11 and a reinforcing layer 13. In other words, the paper layer 12 is interposed between the wood layer 11 and the reinforcing layer 13, thereby improving the adhesion between the wood layer 11 and the reinforcing layer 13. This is because the surface of the reinforcing layer 13 described later is made of resin, and the resin surface has poor wettability with the adhesive, and as a result, the adhesiveness between the wood layer 11 and the reinforcing layer 13 deteriorates. On the other hand, by interposing the paper layer 12 between the wood layer 11 and the reinforcing layer 13, the wettability between the wood layer 11 and the reinforcing layer 13 that are in contact with the front and back surfaces of the paper layer 12 is improved. Adhesion between the wood layer 11 and the reinforcing layer 13 is enhanced.

  Due to this adhesion, the separation distance from the light emitting element 21 to the reinforcing layer 13 can be set to 0 to 2 mm. By fixing both members within this range, it is possible to provide highly visible appearance light that satisfies both diffusibility and directivity.

(Reinforcing layer)
The laminate 1 with a light emitting function includes a reinforcing layer 13. In the example of FIG. 1, a PET resin sheet is used as the reinforcing layer 13. PET resin (polyethylene terephthalate resin) has a high light guiding effect because of its translucency. Moreover, since it has waterproofness and impact resistance, the rupture of the protruding plate 11 and the sheet layer 14 is prevented and resistance is increased, and since it has heat resistance and is not easily thermally deformed, the influence of heat from the light emitting device 15 can be suppressed. Furthermore, it can be a strong door with good adhesion to the vinyl acetate adhesive used in the present invention and the resin film surface-treated on the paper layer 12 to be bonded.

  The reinforcing layer 13 is preferably adjusted to a thickness of 0.5 to 1.5 mm. This is because, within this thickness range, the reinforcing layer 13 interposed between the wood layer 11 and the sheet layer 14 increases the impact resistance of both members that are in close contact with each other, so that breakage of the members can be avoided. In particular, in the wood layer 11, since the region covering the opening 14 a punched out of the sheet layer 14 has low impact resistance, the opening 14 a is covered with the reinforcing layer 13, and the wood layer 11 is further adhered thereon. Thus, the strength in the vicinity of the opening 14a can be remarkably improved.

  In particular, by arranging the reinforcing layer 13 in front of the sheet layer 14, that is, in a stacking order in which the reinforcing layer 13 is sandwiched between the opening 14 a and the wooden layer 11, the wooden layer 11 is substantially uniformly formed into a planar shape. Can be stretched and fixed. As a result, the opening 14a cannot be recognized from the wood layer 11 side. Specifically, when the opening 14a is bonded with the thin wooden layer 11 without the reinforcement layer 13, the wooden layer 11 may be recessed along the cavity of the opening 14a. As a result, the opening 14a There was a possibility that the existence was recognized from the surface of the door. That is, the reinforcing layer 13 can prevent the thin wood layer 11 and the paper layer 12 from sinking in a region corresponding to the opening 14a.

  Further, the wood layer 11 has its back side in contact with the reinforcing layer 13 to prevent the wood layer 11 from warping, and the design surface of the wood layer 1 is made of wood such as texture, hand, fragrance and wood grain. Leave the features as they are. That is, the thickness of the wood layer 11 can be freely adjusted by the reinforcing layer 13 on the back side, so that the wood layer 11 can be thinned. Thereby, the distribution of the wooden layer 11 with low waterproofness can be reduced, and the tolerance of the whole door can be increased. Furthermore, by further laminating the paper layer 12 between the wood layer 11 and the reinforcing layer 13, in addition to reinforcement and warpage prevention, the non-permeation of the opening 14a from the door surface side can be realized more effectively as described above. It is.

(Sheet layer)
The sheet layer 14 includes an opening 14a punched in the thickness direction. The emitted light emitted from the light source 15 in a predetermined pattern shape passes through the opening 14a, and the transmitted light passes through the wood layer 11 so that light having a predetermined shape appears on the surface of the door 1. That is, the light source light can pass only through the opening 14a in the sheet layer 14, and the blocking part other than the opening 14a is not passed, and therefore the sheet layer 14 plays a role of masking.

  The shape and size of the opening 14 a can be freely determined in consideration of the arrangement region of the light emitting elements 21 constituting the light source 15. Specifically, in addition to a rectangular shape, it may have a curved shape such as a round shape or an oval shape, or may have a desired shape such as a symbol or a mark. In the example of FIG. 1, the rectangular opening is formed by punching with a laser.

  The material of the sheet layer 14 is not particularly limited. In the example of FIG. 1, Lauan plywood is used as the sheet layer 14. Since the lauan material has an appropriate strength and is easy to perform secondary processing such as drilling, it is easy to form the opening 14a. Further, since the dimensional change can be reduced with little deflection, the door can be stably fixed. Further, it is preferable that the core material is prevented from being raised from the surface side of the door, and exposure of the inner member of the door can be avoided.

  Moreover, in order to make effective the effect which avoids permeation | transmission of the opening part 14a from the surface side of a door with the reinforcement layer 13 as mentioned above, the thickness of the reinforcement layer 13 is made into the range of 2.4-2.7 mm. It is preferable to adjust. More preferably, the ratio of the thickness of the reinforcing layer 13 to the thickness of the sheet layer 14 is in the range of 1: 2.4 to 1: 5.4. If the thickness of the sheet layer 14 is within this range, when the light is irradiated from the light source 5a toward the wood layer 11, the lighting pattern of the light passing through the opening 14a of the sheet layer 14 is clearly reflected on the wood layer 11. On the other hand, if the thickness of the sheet layer 14 with respect to the reinforcing layer 13 is larger than the above ratio, the shadow of the opening 14a of the sheet layer 14 caused by the thickness of the sheet layer 14 is likely to be reflected on the wood layer 11. Become. Therefore, by limiting the thicknesses of both members to the above range, the effect of the reinforcing layer 13 becomes more effective, and the shape of the opening 14a of the sheet layer 14 can be prevented from being exposed from the surface side of the door. By adjusting the thickness and transmittance of the reinforcing layer 13 according to the thickness of the sheet layer 14, the light from the light source 15 can be diffused so that the contour of the shape of the opening 14a cannot be visually recognized.

  In Example 1, a protruding plate 11 having a thickness of 0.2 mm, a reinforcing shoji paper 12 having a thickness of 0.1 mm, a PET resin sheet 13 having a thickness of 1 mm, and a lauan plywood 14 having a thickness of 2.5 mm were used. However, these are merely examples, and the thickness of each member can be appropriately set according to the thickness of the entire door, the light emission intensity of the light source 15, and the like.

(Adhesive)
The adhesive for pasting each member is not particularly limited as long as it can use a solvent-based pressure-sensitive adhesive and can stably bond each member such as a resin adhesive or cyanoacrylate. A plurality of adhesives may be used. Among these, vinyl acetate is suitable as a paper paste, and can enhance both the adhesiveness with the paper layer 12 and can fix both members within a suitable distance between the light source 15 and the wood layer 11. In particular, by using vinyl acetate, the light transmittance of the paper layer 12 in a state absorbed by the paper layer 12 is suitable, and the emitted light is directed at a separation distance w within a specified range between the light source 15 and the paper layer 12. It is preferable that the balance between the diffusibility and the diffusibility is further increased, and that a lighting pattern having high visibility can be seen even from multiple directions.

(light source)
FIG. 3 is a plan view of the light source 15. As shown in FIG. 3, the light source 15 is a collection of light emitting elements 21 that are a plurality of point light sources. Specific examples include semiconductor elements such as LEDs and LDs, organic EL, and fluorescent lamps using luminescence.

  In the example of FIG. 3, an LED is used as the light emitting element 21. As a result, it can be driven at a low voltage and a low current, so that power consumption can be suppressed, durability and reliability can be improved, and power consumption can also be reduced. In addition to high brightness, various colors can be reproduced by mixing red, green, and blue light at an appropriate ratio. Furthermore, since the LED is robust and excellent in impact resistance, it is suitable for use in a dynamic door that also generates an impact due to an opening / closing operation. In addition, since it has a long life, it is possible to reduce the labor and cost of replacing the light source and to realize maintenance-free. Furthermore, since the calorific value is small, the thermal influence on the surrounding members is relatively small. In Example 1, the LEDs 21 are arranged on the substrate 22 in parallel with the front and back surfaces of the door and in a matrix. The number of LEDs used is appropriately set according to the size of the sign pattern to be displayed, the required light quantity, and the like. Since the LED is a current control element, the light emission amount can be adjusted by the current amount, and the output linearity is excellent and preferable.

  Moreover, although LED of various shapes, such as a cannonball type and a surface mounting type | mold, can be employ | adopted as LED21, a surface mounting type | mold (SMD type | mold) LED with thin thickness is preferable. Thereby, the thickness of the door can be easily changed. For example, the thickness of the door can be reduced, and the thickness of the door can be adjusted via a spacer to add another member such as a heat insulating material.

  The light source 15 includes an LED group 21a in which LEDs 21 are arranged in a matrix of a plurality of rows and a plurality of columns in a planar shape. Each LED 21 is arranged in a direction in which the traveling direction of the emitted light is substantially orthogonal to the wood layer 11. Further, the number of mounted LEDs 21 is not particularly limited, and can be, for example, 4 rows × 4 columns, 16 rows × 16 columns, 24 rows × 24 columns, or the like. If the number of LEDs 21 is increased, the number of dots constituting the lighting pattern increases, so that the contour of the appearance lighting pattern can be expressed smoothly. On the other hand, heat generation and power consumption by the light source can be reduced by suppressing the number of placement. In the example of FIG. 3, three unit-shaped LED groups in which 4 rows × 4 columns are mounted on one substrate 22 are connected in a straight line. For convenience, the first LED group 21a and the second LED group from the left in FIG. 21b and the second LED 21c. Since the unit-shaped LED group can connect the LED groups having the same shape in a daisy chain, it can correspond to light emitting areas of various sizes by changing the number of connections. Moreover, the light source 15 may mount all the LEDs 21 on one substrate 22, or may prepare a different substrate for each LED group. In the example of FIG. 3, the boards 22a, 22b, and 22c on which the LED groups 21a, 21b, and 21c can be mounted are arranged apart from each other, and are fixed by fixing ribs 23 that connect parts of the boards 22a, 22b, and 22c. ing. In this way, by providing a plurality of substrates 22 corresponding to each small group of the light emitting elements 21 and separating the substrates 22 from each other, the surface area capable of exposing the substrate 22 to which heat generated from the light emitting elements is conducted to the outside air. As a result, heat dissipation is improved, which is preferable.

  Therefore, the substrates 22a, 22b, and 22c are preferably made of a material that fixes the light emitting element 21 and has excellent thermal conductivity. Thereby, heat dissipation can be further improved and the life life of the light emitting element 21 can be improved. Specifically, a glass epoxy substrate, a flexible substrate, or a ceramic substrate can be used. Further, the number of the substrates 22 is not particularly limited, and can be appropriately determined depending on the display area of the lighting pattern. Further, the arrangement direction of the substrates 22 is not particularly limited, and the substrates 22 can be arranged in various ways such as a straight line or a plane. In the example of FIG. 3, three substrates 22 are arranged in a straight line, and the light source 15 in which the LED 21 is mounted on each substrate 22a, 22b, 22c is arranged so that the direction of the arrangement of the substrates 22 is horizontal with respect to the door. It is fixed. If it is this arrangement direction, as shown in FIG.2 (b), it is suitable for the form which displays a lighting pattern on the surface layer of the door 1 side by side. However, the arrangement direction of the substrates 22 may be a vertical direction, and in this case, the appearance lighting pattern is suitable for a vertical display as shown in FIG. In this manner, by mounting the light emitting elements 21 in a dot matrix shape and controlling the blinking of each light emitting element 21, the display of the lighting pattern can be recognizable without depending on the arrangement direction of the substrates 22.

  The material of the fixing rib 23 is also preferably a material having high thermal conductivity, for example, a metal such as copper or aluminum. Thereby, the heat dissipation from the light emitting element 21 can be improved, which is preferable. Further, by configuring the fixing rib 23 in white or silver, the reflectance can be increased and the light extraction efficiency can be improved. In the example of FIG. 2, the fixing rib 23 is made of aluminum to enhance the reflectivity as well as the heat dissipation. Specifically, the light emitted from the light source 15 is reflected by the intermediate member such as the paper layer 12 and the return light that has traveled to the light source 15 side is reflected again by the fixing rib 23 toward the wood layer 11 side, thereby reducing the optical loss. Can be reduced.

  FIG. 5 is a cross-sectional view taken along line V-V ′ of FIG. 2. Further, a partially enlarged view of a region indicated by a circle is also shown in FIG. As shown in FIG. 5, the light emitting element 21 of the light source 15 is accommodated in the opening 14 a of the sheet layer 14. Moreover, it is preferable to fix the light emitting element 21 so that the separation distance w from the light emitting element 21 to the reinforcing layer 13 is 0 mm to 2 mm. As a result, as shown by the arrows in FIG. 5, in the traveling direction of the emitted light from the light emitting element 21, the image of the lighting pattern appearing on the surface of the wood layer 11 is made clear by increasing the directivity up to the wood layer 11. In addition, the diffusibility of light can be increased farther from the wood 11 and the viewing angle of the lighting pattern can be increased.

  Further, as shown in FIG. 5, a spacer 24 may be sandwiched between the sheet layer 14 and the support layer 16. The distance w from the light emitting element 21 to the wood layer 11 can be adjusted by the thickness of the spacer 24. With the above arrangement structure, at least a part of the fixing rib 23 of the light source 15 is exposed to the opening 14a or the air layer in the gap in the door 1 to dissipate heat, so that the cooling effect of the light source 15 is enhanced. Furthermore, a ventilation hole is provided in a part of the door 1 so that the opening 14a of the door 1 and the outside of the door 1 can be ventilated through the ventilation hole, so that a further heat radiation effect can be obtained. At this time, since heat is directed upward, it is preferable to provide a ventilation hole above the door.

  Further, a separate heat sink can be provided to further improve heat dissipation. Or you may provide the heat conduction path | route which conducts the heat_generation | fever of LED to the exterior inside a door. For example, by disposing a heat conductive lead so as to be in contact with a metal member such as a butterfly plate used for opening and closing a door, effective heat dissipation can be achieved using an existing member. In this way, by designing the LED in consideration of heat dissipation, the LED can be stably operated, and the reliability can be improved and the life can be extended.

  Further, in FIG. 5, the support layer 16 is not necessarily the rearmost surface of the door. A member may be further provided on the back side of the support layer 16 to adjust the thickness of the door 1. In addition, a translucent substrate, a light emission wavelength conversion layer, a diffusing plate, or the like can be interposed in front of the support layer 16, whereby various characteristics of the lighting pattern appearing on the surface of the door 1 can be achieved.

  FIG. 6 is a block diagram showing a connection state with an external power source and a controller in addition to a plan view of the support plate 16 and the light source 15 fixed thereto. The light source 15 shown in this figure is connected to the controller 26 via the lighting control means 25. The controller 26 is connected to the signal source SS, and the controller 26 sends a lighting control signal to the lighting control means 25 based on the lighting pattern input from the signal source SS. On the other hand, the light source 15 is connected to the power source PS via the switch SW, and receives supply of driving power therefrom.

  As shown in FIG. 6, the light source 15 is connected to a controller 26 that can control the drive current and drive pattern of the light emitting elements that constitute the light source 15. A signal input from the signal source SS to the controller 26 is transmitted to the lighting control means 25 to control the lighting state of each light emitting element 21. In the example of FIG. 6, the lighting control unit 25 is configured to be connected to an external power source PS to supply power. As the power source PS, a commercial power source such as AC100V or a battery such as a battery can be used. In particular, the use of a rechargeable battery is preferable because it can supply power to the light source 15 cordlessly. The rechargeable battery can be charged by a contactless charging method using electromagnetic induction or the like, in addition to a priority connection method in which a power line is connected to the power source PS.

  The power source PS is connected to the lighting control means 25 via the switch SW. The user can switch the lighting pattern display ON / OFF by manually operating the switch SW. Also, a sensor is provided in the switch SW so that the switch is automatically turned ON / OFF when the switch is opened or closed, or the timer is used to turn the switch ON / OFF after a predetermined time, or the external trigger is turned ON / OFF. Etc. For example, if the switch SW is provided with an antenna capable of receiving a wireless lighting signal, and the lighting signal is input wirelessly in the event of an emergency such as a fire, the “emergency exit →→→” with a lighting pattern provided in an appropriate position in advance. It can be used as an emergency guide light by displaying characters such as or arrows, or blinking or scrolling them. In the example of FIG. 6, the switch SW is used in combination with the power connector with the power source PS. However, the configuration is not limited to this configuration, and a switch may be provided separately. The switch SW may incorporate a converter or a transformer that can convert the supplied current into an LED drive current. Furthermore, the switch SW can be integrated with the lighting control means.

  When the user inputs a lighting pattern to the light source 15 to the controller 26 or by inputting a lighting pattern via a signal source SS such as a computer or an external source connected to the controller 26, The LED drive current is transmitted to the lighting control means 25 via the controller 26 as a command signal. Further, a signal is transmitted to each LED 21 mounted on the substrate 22 via the lighting control means 25, and thereby the lighting state of each LED 21 can be controlled.

  In addition, the lighting control means 25 can incorporate a memory unit 28 and the lighting pattern can be stored in the memory unit 28. Specifically, the controller 26 is connected to the lighting control means 25 to input a lighting pattern, and is stored in the nonvolatile memory of the memory unit 28. Thus, after transmitting the lighting pattern to the memory unit 28, the controller 26 is removed, and the subsequent lighting pattern of the light emitting element 21 operates according to the designated program. By adopting a configuration in which the controller 26 and the lighting control means 25 are detachable as described above, the controller 26 can be connected to the lighting control means 25 only at the time of setting, and this can be removed and simplified during operation. The lighting pattern once set can be changed by connecting the controller 26 again.

  In the example of FIG. 6, three substrates 22 are arranged in parallel horizontally, and the lighting control means 25 is wired only to the closest right substrate 22 c, and is wired from this substrate 22 c to the adjacent central substrate 22 b, Further, wiring is performed from the central substrate 22b to the adjacent left substrate 22a. Thus, by making the circuit of each board | substrate common, even if it is a case where a board | substrate is connected in a row and the mounting number of a board | substrate is increased, wiring can be made easy and it is preferable.

  With the above structure, the controller 26 emits light characteristics such as the color tone and luminance of the light emitted from each LED 21, or lighting patterns such as blinking, gradation, and flash, the amount of current supplied, ON duty, OFF duty, lighting cycle (frequency), etc. Can be adjusted. As a result, the lighting pattern and the light emission amount of the light emitting element 21 can be changed, and various lighting patterns as the entire light emitting region can be expressed. In particular, as shown in FIG. 5, when the visibility of the lighting pattern is enhanced by setting the distance w from the light emitting element 21 to the reinforcing layer 13 to be 0 mm to 2 mm, the member adjacent to the light emitting element 21 generates heat from the light emitting element 21. May cause discoloration or deformation. By turning on each light emitting element 21 intermittently without continuously lighting, the influence of such heat can be reduced and the durability of the member can be increased. For example, by setting the pause time to 0.5 seconds or more or the duty ratio to 50% or less by the controller 26, the adverse effect on each of the above members can be reduced, and the amount of outgoing light passing through the wood layer 11 can be made appropriate. Also, it can be expected to increase the alerting by flashing. Further, by separating the distance w, the balance between sharpness and smoothing at the edge of the lighting pattern is improved, and visibility is preferably increased.

  In addition, the controller 26 controls the input current to the light emitting element 21 to 5 mA to 15 mA, thereby limiting the luminance in the light emitted from the light emitting element 21 and preventing the influence of the light source 15 from being burned on other members. You can also In addition, by controlling the input current, it is possible to obtain an advantage that power consumption is reduced and the amount of heat generated by the light source is suppressed. In addition, the maximum output (rated output) of the light source 15 in Example 1 was 440 W (average 176 W, 1500 mA), for example.

  In addition, by representing characters and diagrams by blinking of the light emitting elements, it is possible to variously change the lighting pattern that appears over time. As a result, the visual effect can be enhanced, and a large amount of information can be displayed without physical restrictions such as the width of the door by changing the lighting pattern expressed in a certain appearance region with a time difference. Since moving characters or flowing characters can be expressed in this way, it is easier to attract attention, and it is particularly suitable for advertising because of the unexpectedness of displaying characters on the grain.

(Processing to the final shape of the door)
Desired parts such as a handle, a handle 17, a handle, a push plate, a lock, a door wheel, a rail, and a hinge are added to the door 1 composed of the above-mentioned multiple layers and processed into a final shape. The door shown in FIG. 1 is a hinged door having a handle 17 protruding outward from the surface of the wood layer 11 substantially perpendicular to the surface. However, the type of door is not limited, and can be variously processed such as a sliding door, a hanging door, a partition door, a partition, a folding door, and the like.

(Light display)
Furthermore, the appearance area of the lighting pattern is not limited to the surface on one side of the door. You may display on both the front and back of a door simultaneously. For example, it is possible to realize the configuration in which the light emitted from the light source can travel to both sides facing each other, and the above-described members are arranged symmetrically with respect to the light source. The display method of the lighting pattern appearing on each of the front and back surfaces may be the same or different. Thereby, significant characters, designs, etc. can be notified simultaneously on the front side and the back side across the door. On the other hand, when a lighting pattern appears only on the surface on one side, a light blocking sheet may be interposed in order to avoid light leaking to the opposite surface side. In addition, although not shown, a light display unit having a desired shape can be embedded in the vicinity of the door such as a door frame, on the door, under the door, on the side wall of the door, or on the floor. Further, it goes without saying that the lighting pattern can appear on the protruding plate 15 in any shape as long as the structure can support the protruding plate 11 and the light source 15.

  The laminated body 2 with a light emitting function according to Example 2 is the same as the laminated body 1 with a light emitting function according to Example 1 in that the wood layer is stuck on the surface, but is stuck on the back side of the wood layer. The order in which the members are arranged is different. As a laminated body 2 with a light emitting function of Example 2, a door is given as an example in the same manner as in Example 1, and a sectional view of this door is shown in FIG. Further, a partially enlarged view of a region indicated by a circle is also shown in FIG.

  7 includes a surface of a wood layer 11 on the front side of the door 2, and a paper layer 12 and a sheet layer having substantially the same outer shape as the wood layer 11 on the back side of the wood layer 11 (downward in FIG. 7). 14b, the reinforcement layer 13, and the support layer 16 are laminated | stacked in order and substantially parallel. That is, the arrangement of the sheet layer 14b and the reinforcing layer 13 is different from that of the door 1 of the first embodiment. Further, the sheet layer 14a in FIG. 7 is made of a resin), and its thickness is 5 mm. Thereby, the waterproof effect can be enhanced. Further, members other than the sheet layer are made of the same material as that of the member of the first embodiment, and detailed description thereof is omitted.

  The door 2 includes a frame 18 that surrounds the periphery of the wood layer 11. The frame body 18 in FIG. 7 is fixed in contact with the edges constituting the thickness of each member in the stacking direction from the wood layer 11 to the support layer 16. Thereby, since the absorption of the water | moisture content from the thickness direction can be suppressed, it can be set as the highly weather-resistant door 2 which can prevent the dimensional change of each member and the short circuit of a light source also in a high humidity environment. Furthermore, the strength of the door 2 can be increased by the structure in which each member is surrounded by the frame 18.

  The door 3 is shown in FIG. 8 as an example of the laminated body with a light emission function which concerns on Example 3. FIG. This door 3 has the same function as the door 1 of the first embodiment, that is, has a form in which a lighting pattern appears on the surface of the door 3. Moreover, Fig.8 (a) shows the appearance state of the lighting pattern in the door 3, FIG.8 (b) shows the top view of a support plate and the light source fixed to this. The same members as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  The door 3 of FIG. 8 is provided with a plurality of regions where lighting patterns appear in the wood layer 11 of the door 3. Specifically, in the example of FIG. 8A, a collection of cherry blossom petals can be expressed at the top of the door, and a plurality of areas that can express a single petal are provided below this petal collection. Yes. Then, by controlling the blinking state of the light emitting elements constituting each light source 15 as in the first embodiment, the appearance area of the lighting pattern is changed at any time, for example, the petals are blinked in order from top to bottom. It expresses a moving image that flutters.

  This door 3 is made by contacting the same members as the door 1 of the first embodiment in the same order. However, the opening 14a of the sheet layer 14 in FIG. 1 is punched in advance into a shape in which a lighting pattern is to appear. The light emitting elements are arranged in a planar area that can at least include the area of the opening 14a, and light emitted from the light emitting element passes through the opening 14a so that the shape of the opening 14a is changed to the surface side of the door 3. It is configured to float on the surface.

  Further, as shown in FIG. 8B, the door 3 has a partition member 19 disposed between the adjacent light sources 15 in each light source 15 capable of irradiating the respective openings. Thereby, it can avoid that emitted light mixes in a mutual irradiation area. As a result, it is preferable that the blinking of the lighting pattern can be clearly distinguished on the surface of the door.

  Moreover, although the laminated body 4 with a light emission function of Example 4 has a function similar to Example 1, the shape of the opening part 14a of the sheet | seat layer 14 differs. In other words, the sheet layer 14 is cut into a predetermined pattern to form a plurality of opening pieces, and a pattern along the shape of the opening pieces is combined to make letters and numbers appear on the surface layer of the door 4. Specifically, FIG. 9 is a partially enlarged view showing the shape of the opening 14a of the sheet layer 14 according to the fourth embodiment. In FIG. 9A, a plurality of openings constituting a so-called 7-segment display shape are formed, that is, the opening 14a is composed of seven opening pieces 27. On the back side of the opening area, there are LEDs that can irradiate light in a substantially vertical direction with respect to the individual opening pieces 27. By turning each LED on and off individually, the opening pieces 27 are sequentially blinked. A lighting pattern along the shape of the opening piece 27 can be raised on the surface of the door. These lighting patterns can be combined to express Arabic numerals.

  With the above structure, it suffices to irradiate only the region corresponding to the segment. Therefore, the LEDs need only be arranged in the region including each opening 14a. As a result, it is not necessary to closely parallel all rectangular areas covering the displayable numbers by the LEDs, and the number of LEDs mounted can be reduced. As a result, the cost can be reduced and the life of the laminate 4 with a light emitting function can be extended by suppressing the amount of heat generated from the light source. Moreover, in the example of FIG. 9, since each segment which comprises a number is spaced apart compared with the dot-matrix arrangement | sequence of LED, the penetration | invasion of the light to another opening area can be reduced extremely, and as a result. The outline of the character shape displayed as a whole can be reduced and the outline can be clarified.

  Further, FIG. 9B shows a 14-segment display, and FIG. 9C shows a 16-segment display, that is, “X (4 segments)” in “8” of 7 segments in FIG. 9A. And a shape corresponding to “I (2 segments)”. By forming the opening pieces 27 in this way, the alphanumeric characters displayed on the surface of the door can be displayed in an easy-to-understand manner, and the display types and display methods can be varied.

  The laminate with a light emitting function of the present invention can be applied as a door, a bulletin board, an information transmission device, a floor, a ceiling, a panel, and a signboard.
