  However, the flooring material having the illumination function disclosed in Patent Document 1 has a tempered glass floodlight exposed in a floodlight window that is a portion surrounded by a floor finish placed on the surface of the floodlight cover. Therefore, regardless of whether the lighting device is turned on or off, a tempered glass floodlight plate that is different from the floor finish material is exposed on a part of the floor material surface. There may be gaps and steps at the boundary with the light plate, making it difficult to walk as a flooring material, and there is a problem that the boundary and gaps become clogged with dirt, and a part of the surface is made of tempered glass. As a result, the presence of the lighting device was always visible and the appearance of the flooring surface was poor.

  The present invention was invented in view of the above-described conventional problems, and a part of the decorative surface on the surface of the building material can be brightly shined, and the brightly shining portion and the non-lightly shining portion of the building material surface It is an object of the present invention to provide a building material that can prevent a gap or a step from being generated at the boundary between the surface and the surface, and that does not deteriorate the appearance of the surface even though a part of the surface is illuminated.

  In order to solve the above problems, the present invention has the following configuration.

  The building material having a lighting function according to the present invention is formed by leaving a panel body 2 having a decorative surface 1 on the surface and a surface-side thin portion 3 having at least the surface of the decorative surface 1 in the thickness direction of the panel body 2. The light emitting unit housing recess 4 and the light emitting unit 5 housed in the light emitting unit housing recess 4 are provided. And this invention is characterized by the surface side thin part 3 which the surface became the said decorative surface 1 having the light transmittance which enables permeation | transmission of the light of the said light emission part 5. It is characterized by the above-mentioned.

  By setting it as such a structure, when the light emission part 5 is lighted, light will permeate | transmit the surface side thin part 3, and a part of decorative surface 1 of the surface of the panel main body 2 will shine. When the light emitting unit 5 is turned off, only the decorative surface 1 can be seen on the surface of the panel body 2, so that it is not possible to distinguish between a portion that emits light and a portion that does not emit light.

  Moreover, it is preferable to provide the regulation means 6 for making the center part except the peripheral part of the surface side thin part 3 into the true direct-light region by the light source 5a of the light emission part 5 seeing from the surface side.

  By adopting such a configuration, the central portion excluding the peripheral portion as viewed from the surface side of the surface-side thin portion 3 through which light is transmitted has a large amount of light transmission, and the peripheral portion has a small amount of light transmission. This can be a region, whereby a portion of the surface of the decorative surface 1 that glows (the central portion of the surface-side thin portion 3) and a portion of the decorative surface 1 that does not shine (surface side) The peripheral portion of the thin-walled portion 3 is present, the boundary between the shining portion and the non-shining portion of the decorative surface 1 blurs, and the outer peripheral edge of the light-emitting portion storing concave portion 4, that is, the outer peripheral edge of the surface-side thin portion 3 is It is possible to create a soft expression that is not emphasized and that the decorative surface 1 itself emits light.

  Further, a through-hole 9 is formed in the base material 7 to be the light-emitting portion housing recess 4 penetrating the front and back, and a decorative material 8 for forming the decorative surface 1 is laminated on the surface of the base material 7 to form a panel It is preferable that the main body 2 is formed and the surface-side thin portion 3 is constituted by a portion corresponding to the light emitting portion housing recess 4 of the decorative material 8.

  Thus, the through-hole 9 used as the light emission part accommodation recessed part 4 is formed in the base material 7, and the cosmetic material 8 is laminated | stacked on the surface of this base material 7, The light emission part accommodation which left the surface side thin part 3 was left. The panel body 2 in which the surface having the concave portion 4 becomes the decorative surface 1 can be easily formed.

  In addition, from the back surface side of the base material 7 to the front surface side of the base material 7, a hollow hole 11 is formed on the front surface side of the base material 7, leaving a thin remaining portion 10 and serving as a light emitting part housing recess 4. The panel body 2 is formed by laminating the decorative material 8 for forming the decorative surface 1, and the surface-side thin portion 3 is constituted by the thin remaining portion 10 and the portion corresponding to the thin residual portion 10 of the decorative material 8. Is preferred.

  In this way, the thin-walled remaining portion 10 is left from the back surface side of the base material 7 to form the punched holes 11, and the decorative material 8 is laminated on the surface of the base material 7, thereby leaving the front-side thin-walled portion 3. It is possible to easily form the panel body 2 in which the surface having the recess 4 for storage is the decorative surface 1. Further, the thin-walled remaining portion 10 can be reinforced and a thin decorative material 8 can be used.

  In the present invention, since the surface-side thin portion whose surface is the decorative surface as described above has light transmittance that enables light transmission of the light emitting portion, by turning on the light emitting portion, Part of the decorative surface itself on the surface of the panel body can shine, and part of the decorative surface shines like this, so there is a step at the boundary between the shining part of the surface and the non-shining part as in the past, or a gap Does not occur. Also, by turning off the light emitting part, part of the light emitting part of the decorative surface disappears, it is indistinguishable from other parts of the surface, the presence of the light emitting part is not known from the surface side, the surface of the building material Appearance does not deteriorate.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The building material 12 having a lighting function according to the present invention includes a panel body 2 having a light emitting part accommodating recess 4 and a light emitting part 5 accommodated in the light emitting part accommodating recess 4.

  The light-emitting portion storage recess 4 is formed by leaving at least the surface-side thin portion 3 made of the decorative surface 1 in the thickness direction of the panel body 2, and the surface-side thin portion 3 is a light-emitting portion storage recess. The light from the light emitting unit 5 housed in 4 can be transmitted.

  In the embodiment shown in FIG. 1, through-holes 9 penetrating front and back are formed in a plate-like base material 7 such as plywood, particle board, MDF, HDF, OSB, etc., and light transmittance is formed on the surface of the base material 7. The panel main body 2 is formed by laminating and integrating a thin plate-like or sheet-like decorative material 8 such as a thin projecting plate or a decorative sheet. In the present embodiment, the through-hole 9 provided in the base material 7 becomes the light-emitting portion housing recess 4, and the portion corresponding to the light-emitting portion storage recess 4 of the decorative material 8 allows the light-emitting portion 5 to transmit light. The surface side thin portion 3 is formed.

  In the panel body 2, there are a case where the backing material 13 is laminated and integrated on the back surface of the base material 7 and a case where the backing material 13 is not provided.

  When the building material 12 is constructed by laminating and integrating the backing material 13 on the back surface of the panel body 2, the light emitting part 5 housed in the light emitting part housing recess 4 is attached to the backing material 13. As shown in FIG. 4, the building material 12 of this embodiment is a building panel in which the backing 13, the base material 7, and the decorative material 8 are integrated and the light emitting unit 5 is housed in the light emitting unit housing recess 4. Constructed and used as flooring materials, wall materials, ceiling materials, building materials for stairs, fence materials, border materials such as skirting boards and surrounding edges.

  On the other hand, when the backing material 13 is not provided on the back surface of the base material 7, the building material 12 is configured as a set of the panel body 2 not provided with the backing material 13 and the light emitting unit 5 separate from this. Then, as shown in FIG. 3, the light emitting section 5 is attached to a predetermined position on the surface of a base material 14 such as a floor base, a wall base, a ceiling base, or the like, or a base material 14 such as an exterior base material. The panel main body 2 not provided with the backing material 13 is attached to the surface of the base material 14 so that the light emitting section 5 is positioned in the light emitting section housing recess 4 opened on the back side of the main body 2.

  Although not shown, even if the backing material 13 is laminated and integrated on the back surface of the base material 7, the through holes 9 and the punched holes 11 formed in the base material 7 are part of the backing material 13. If it is formed so as to open, the construction is performed in the same manner as in the case where the backing material 13 is not provided.

  In any of the above cases, there is provided a regulating means 6 for making the central portion excluding the peripheral portion of the surface-side thin portion 3 as a true direct area M by the light source 5a of the light-emitting portion 5 when viewed from the surface side.

  In the embodiment shown in FIGS. 1, 5 (a), and (b), the restricting means 6 is configured by superposing the light collecting member 15 on the back side of the front side thin portion 3. The light condensing member 15 serving as the restricting means 6 is a light transmitting portion in which the central portion transmits light to the back surface of a transparent or translucent plate-like light transmitting portion 16 made of a synthetic resin such as polypropylene, polyethylene, acrylic, ABS, or polyacetal. The light-shielding part 18 which becomes 17 is provided.

  In the embodiment shown in FIG. 1 and FIG. 5 (c), a non-light-transmissive light-shielding plate and a light-shielding sheet in which an opening serving as a light-transmissive portion 17 is provided at the center on the back surface of the light-transmissive portion 16. This is an example in which the light shielding portion 18 is formed. In the embodiment of FIG. 5B, the light-shielding portion 18 that does not transmit light and the light-transmitting portion 17 that transmits light are formed on the back surface of the light-transmitting portion 16 by printing. In the case of attaching the light transmitting plate and the light transmitting sheet, a light shielding portion 18 that does not transmit light and a light transmitting portion 17 that transmits light are formed on the light transmitting plate and the light transmitting sheet. Also good. In printing, the light-transmitting part 16 may allow more light to pass through gradation printing, and the light-shielding part 18 in the surrounding area may reduce the amount of light passing.

  In any case, in the above-described embodiment, the light emitted from the light source 5a of the light emitting unit 5 is regulated by the light shielding unit 18, and enters the light transmitting unit 16 from the light transmitting unit 17 in the central portion, and the surface side thin portion. Light 3

  In this case, an annular imaginary line connecting points where the extended lines of the line L connecting the respective points around the light transmitting part 17 at the center of the light shielding part 18 and the light source 5a of the light emitting part 5 intersect with the surface side thin part 3 respectively. The region surrounded by is the spreading region of the light source 5a of the light emitting unit 5 in the surface side thin portion 3, that is, the true direct region M by the light source 5a of the light emitting unit 5 in the surface side thin portion 3. When the light emitting portion 5 is turned on, the entire surface side thin portion 3 shines because it has translucency. However, the surface side thin portion 3 is illuminated by the light source 5a of the light emitting portion 5 in the surface side thin portion 3. The true direct-light region M has a large amount of light and shines brightly, and its peripheral part is not the true direct-light region M of the light source 5a of the light-emitting unit 5, so that one of the light refracted or reflected in the light-transmitting part 16 It becomes the area | region N which dimly shines in a part. In addition, the outer peripheral portion, which is the region N that shines dimly around the direct-light region M, becomes more blurred as it approaches the outer peripheral end of the surface-side thin portion 3.

  In this way, the light from the light source 5a of the light emitting unit 5 is regulated by the regulating means 6, and the central portion of the surface side thin portion 3 has a large amount of light transmission and shines brightly, and the surrounding area has a small amount of light transmission. By making it shine brightly, a portion (surface) that shines dimly between a part of the surface of the decorative surface 1 that shines brightly (the central part of the surface-side thin portion 3) and a portion of the decorative surface 1 that does not shine A peripheral portion of the side thin portion 3) exists. As a result, the boundary between a part of the decorative surface 1 that shines brightly and a portion that does not shine at all is blurred, and the outer peripheral edge of the light-emitting portion housing recess 4, that is, the outer peripheral edge of the surface-side thin portion 3 is not emphasized. It is possible to create a soft expression such that 1 itself emits light.

  Here, in the embodiment of FIG. 1, the portion facing the light transmitting portion 17 on the back surface of the light transmitting portion 16 is recessed so as to be thinner than the other portions. The lighted portion easily passes light compared to the thick portion, and therefore, the central portion of the surface-side thin portion 3 can be made to shine brighter than the surroundings. In this way, when the portion facing the light transmitting portion 17 on the back surface of the light transmitting portion 16 is recessed and formed thinner than the other portions, the central portion of the back surface of the front side thin portion 3 is arcuate in cross section as shown in FIG. The difference in brightness at the boundary between the outer peripheral edge of the brightly shining area at the center of the thin portion 3 on the surface side and the inner peripheral edge of the dimly shining area N at the periphery is made as small as possible. To make the boundary inconspicuous.

  FIGS. 1B and 1C show an example of the shape and size of the translucent part 16, FIG. 1B is a bottom view of the translucent part 16, and FIG. 1C is FIG. It is sectional drawing of the YY line | wire of (). In FIG. 1C, α indicates the diameter of the recess on the back surface, β indicates the thickness of the light transmitting portion 16, and γ indicates the thickness of the thinnest portion of the light transmitting portion 16. The α and β are both 1 mm or more, and γ is 0.5 mm or more.

  Further, as in each of the above-described embodiments, in the case where the restricting means 6 is configured by overlapping the light collecting member 15 on the back surface side of the front surface side thin portion 3, the front surface side thin portion 3 is reinforced from the back surface side. it can. Therefore, in this embodiment, the restricting means 6 serves to restrict light when the surface side thin portion 3 is irradiated from the light source 5 a of the light emitting portion 5 and to reinforce the surface side thin portion 3.

In the present embodiment, the extension lines of the lines connecting the points around the tip of the screen part 19 and the light source 5a of the light-emitting part 5 are each surrounded by an annular virtual line connecting the points where the surface-side thin part 3 intersects. The region is a spread region of the light source 5a of the light emitting unit 5 in the surface side thin portion 3, that is, a true direct region M by the light source 5a of the light emitting unit 5 in the surface side thin portion 3.

  Also in the present embodiment, when the light emitting unit 5 is turned on, the entire surface side thin portion 3 shines because it has translucency, but the surface side thin portion 3 shines in the surface side thin portion 3. The central part, which is the true direct area M of the light source 5a of the light emitting part 5, has a large amount of light and shines brightly, and its peripheral part is not the true direct area of the light source 5a of the light emitting part 5, so it is refracted in the light transmitting part 16. Or a region N in which a part of the reflected light shines thinly.

  Therefore, also in this embodiment, the light from the light source 5a of the light emitting unit 5 is regulated by the partitioning unit 19 which is the regulating means 6, and the central portion of the surface side thin portion 3 has a large amount of light transmission and shines brightly. The surrounding area has a small amount of light transmission and shines dimly, so that a portion of the surface of the decorative surface 1 shines brightly (a central portion of the surface-side thin portion 3) and a portion of the decorative surface 1 that does not shine. There will be a dimly shining part (a peripheral part of the surface-side thin part 3). As a result, the boundary between a part of the decorative surface 1 that shines brightly and a portion that does not shine at all is blurred, and the outer peripheral edge of the light-emitting portion housing recess 4, that is, the outer peripheral edge of the surface-side thin portion 3 is not emphasized. It is possible to create a soft expression such that 1 itself emits light.

  Further, FIG. 6B shows still another embodiment. The present embodiment is an example in which the light-emitting unit 5 itself is provided with a restriction means (not shown) for restricting the direction in which light is emitted from the light source 5a. In this embodiment, the light emitted from the light source 5a regulated by the regulating means is regulated, and the light source of the light emitting unit 5 in the surface side thin part 3 is the central part of the surface side thin part 3 when viewed from the surface side. This is a spread area of 5a, that is, a true direct-light area M by the light source 5a of the light emitting section 5 in the surface side thin portion 3.

  Also in the present embodiment, when the light emitting unit 5 is turned on, the entire surface side thin portion 3 shines because it has translucency, but the surface side thin portion 3 shines in the surface side thin portion 3. The central part, which is the true direct area M of the light source 5a of the light emitting part 5, has a large amount of light and shines brightly, and its peripheral part is not the true direct area of the light source 5a of the light emitting part 5, so it is refracted in the light transmitting part 16. Or a region N in which a part of the reflected light shines thinly.

  Also in this embodiment, the central portion of the surface-side thin portion 3 has a large amount of light transmission and shines brightly, and the surrounding area has a small amount of light transmission and shines dimly, and a part of the decorative surface 1 on the surface shines brightly. There is a portion (the peripheral portion of the surface-side thin portion 3) that shines dimly between the portion (the central portion of the surface-side thin portion 3) and the non-lighting portion of the decorative surface 1, and a portion of the decorative surface 1 shines brightly. A soft expression in which the boundary between the portion and the portion that does not shine at all is blurred and the outer peripheral edge of the light-emitting portion housing recess 4, that is, the outer peripheral edge of the surface-side thin portion 3 is not emphasized, and the decorative surface 1 itself emits light. Can be created.

  Next, FIGS. 7A, 7B, 7C, 7D, and 7E show still other embodiments of the present invention.
