Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting interior material and a lighting method using the same, and more particularly, to a daylighting interior material used for introducing natural light into a room as an auxiliary to indoor lighting in a building or a general house. In addition, the present invention relates to a daylighting method using the same as a ceiling material or a wall surface material.

  In recent years, various systems for introducing natural light into a room as an auxiliary to indoor lighting have been proposed and actually adopted in buildings and ordinary houses with poor sunlight. In many cases, natural light entering from an opening such as a window is reflected by a reflecting means arranged in the room to reach a place where natural light is difficult to reach.

  For example, Patent Document 1 (Japanese Patent Laid-Open No. 2009-266794) discloses a solar of a building window using, as a solar illuminator, a panel in which a transparent material and a reflective surface are alternately arranged in a horizontal grid pattern by assembling or integrally forming. A system is disclosed that is attached to a portion that is exposed to light, guides sunlight toward the indoor ceiling by the action of refraction and reflection, and reflects the reflected light to the ceiling for use in illumination.

  However, in these systems, since the ceiling has a special specification including the reflecting means and the like, installation takes time and cost, and it cannot be easily adopted. Moreover, when installing a reflecting plate in a ceiling, the part may separate from a surrounding site | part and it may stand out, and there exists a possibility that it may deteriorate in appearance.

  As described above, in the case of the conventional daylighting system, since the ceiling has a special specification including the reflecting means and the like, installation takes time and cost, and the appearance may be deteriorated. Therefore, the present invention can be constructed by a method that is not particularly different from ordinary ceiling construction and wall construction, and uses an interior material for lighting that makes it possible to easily introduce a daylighting system at a low cost. It is an object to provide a daylighting method.

  The invention according to claim 1 for solving the above-mentioned problem is an interior material for daylighting formed by molding a thin metal plate substrate having light reflection / diffusibility on the surface into an interior material shape. .

  In one embodiment, the substrate is a metal plate that is coated with a resin decorative film having light reflection / diffusibility. The decorative film and the metal plate may be provided with pinholes that communicate with each other over the entire surface, and in that case, a heat insulating and sound absorbing material may be provided on the back surface side.

  In one embodiment, the substrate is obtained by applying and printing a light reflecting / diffusing paint on a metal plate. In some cases, pinholes are formed through the entire surface of the metal plate. In that case, a heat insulating and sound absorbing material may be provided on the back surface side.

  In one embodiment, the substrate is formed into a spandrel, system ceiling unit, louver rib or other interior material shape.

  The invention according to claim 8 for solving the above-described problem is that the interior material for lighting according to any one of claims 1 to 7 is disposed in a portion exposed to external light or a peripheral portion of an indoor light source. This is a characteristic daylighting method.

  The present invention is as described above, and the interior material for lighting according to the present invention includes a thin metal plate substrate having light reflection / diffusibility on the surface, and a ready-made interior material such as a spandrel or a system ceiling unit. Since it is formed into a shape, it can be manufactured by a method that is not different from that of general interior materials such as spandrels and system ceiling units, and has the effect of being supplied at low cost.

  Further, according to the daylighting method of the present invention, the daylighting interior material is simply disposed in a portion exposed to outside light or a peripheral part of an indoor light source, in other words, mixed with a general interior material. It is possible to realize a daylighting system easily and at low cost simply by constructing as part of normal ceiling construction or wall construction.

It is a perspective view which shows an example (spandrel) of the interior material for lighting which concerns on this invention. It is a principal part expanded sectional view of the interior material for lighting shown in FIG. It is a perspective view which shows the construction example of the interior material for lighting shown in FIG. It is a partial side view which shows another example (unit for system ceilings) of the interior material for lighting which concerns on this invention. It is a perspective view which shows the construction method of the interior material for lighting shown in FIG.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated based on an accompanying drawing. In the interior material for lighting according to the present invention, a substrate 1 made of a thin metal plate 3 having light reflection / diffusibility on the surface is used as a ready-made ceiling material such as a spandrel A or a system ceiling unit B or a wall material. It is formed by molding into an interior material shape.

  As a method of giving light reflection / diffusibility to the surface of the metal plate 3, a method of covering the entire surface of the metal plate 3 with the resin decorative film 2 having light reflection / diffusibility, or the surface of the metal plate 3 A method of applying and printing a light-reflective / diffusible paint on the whole is conceivable. On the decorative film 2 in the method of covering the decorative film 2, an arbitrary pattern or color pattern is thinly printed as necessary. Further, a method of covering such a decorative film 2 with a transparent light reflecting / diffusing film is also conceivable.

  The following description is mainly for the case where the interior material for lighting according to the present invention is formed as a ceiling material. However, the interior material is not limited to the ceiling material, and can also be configured as a wall surface material. It is constructed on the ceiling or wall surface where the external light hits, the peripheral part of the indoor light source, and the like.

  FIG. 1 shows a configuration when the interior material for lighting is formed as a spandrel A. In this case, the substrate 1 is formed in a long shape, and the side walls 5 and 6 are formed by raising two long sides thereof. Locking portions 7 and 8 are formed at the upper end of the. For example, one locking portion 7 is an insertion plate, and the other locking portion 8 is a clamping portion that receives the insertion plate, and the locking portion 7 of one spandrel A is locked to another spandrel A. It is connected horizontally by a method of engaging with the part 8. Thus, the spandrel A can be used in combination with the general spandrel a having the same shape and having no light reflection / diffusibility on the surface.

  A light diffusing / reflecting sheet is used as the decorative film 2 that will be exposed to the human eye, that is, the surface layer, in other words, a wood grain pattern and various other arbitrary patterns and color patterns are printed as thin as necessary. Is done. Alternatively, as described above, a transparent light diffusing / reflecting film may be covered on the decorative film 2 that has been thinly printed. The decorative film 2 is bonded to the metal plate 3 through an adhesive layer such as an acrylic resin adhesive. As the metal plate 3, for example, a thin aluminum alloy plate having a thickness of about 0.6 mm, that is, 0.6 ± 0.2 mm is used.

  In this embodiment, the decorative film 2 and the metal plate 3 may be provided with pinholes 4 and 4a communicating with each other over the entire surface. In this case, the pinholes 4 and 4a may be transparently provided before the decorative film 2 and the metal plate 3 are bonded, and the pinholes 4 and 4a may be bonded together. The method of perforating from the decorative film 2 to the metal plate 3 after wearing is simpler and more efficient because there is no need for alignment.

  The pinholes 4 and 4a are inconspicuous sizes, that is, minute holes of about 0.5 to 1 mm, and are formed at regular intervals (for example, 4 mm) or randomly. When the hole diameter is at this level, when it is disposed on a ceiling surface or a wall surface, it can hardly be visually recognized regardless of a pattern or a color pattern expression applied to the surface.

  Furthermore, in this embodiment, the back surface of the metal plate 3, that is, the space between the side walls 5, 6 may be filled with the heat insulating / sound absorbing material 9. The heat insulating / sound absorbing material 9 is a long molded body having a thickness of about 25 mm such as glass wool (rock wool), foamed resin, etc., which is tightly fitted between the side walls 5, 6, and is bonded and fixed inside the side walls 5, 6.

  Even when a method of applying / printing a light reflecting / diffusing paint on the metal plate 3 as a method of giving light reflecting / diffusing properties to the surface of the metal plate 3, the pinhole 4 a is formed on the entire metal plate 3. In some cases, a heat insulating and sound absorbing material 9 may be provided.

  FIG. 3 shows a state of daylighting by the daylighting method performed using the spandrel A as the interior material for daylighting. The spandrel A manufactured according to the present invention is disposed at least near a window to which external light hits. In a portion where no contact is made, a general spandrel a having the same shape and not reflecting or diffusing light is disposed on the surface. Thus, the external light entering from the opening such as a window is reflected by the spandrel A and guided to the interior direction of the room. In this case, the spandrel A may be used for the entire ceiling. In addition, since the external light which enters from opening parts, such as a window, does not necessarily go to spandrel A, the refracting means which directs external light to spandrel A is arrange | positioned as needed.

  In this case, by using the same color as the spandrel A as the spandrel a, it is possible to give a sense of unity to the whole. Moreover, when the pinholes 4 and 4a are provided as the spandrel A and the spandrel a and the heat insulating / sound absorbing material 9 is disposed, an excellent heat insulating / sound absorbing effect is exhibited. In addition, it is possible to introduce the lighting system according to the present invention by a method of changing a part of the existing spandrel ceiling to the spandle A according to the present invention, not only in the case of newly installed.

  4 and 5 show the case where the interior material for lighting according to the present invention is formed into a unit B for system ceiling. The substrate 1 in this case is a quadrangle, and the peripheral wall 10 is formed by raising the four sides. Moreover, the upper end of the surrounding wall 10 may be bent and the flange-shaped latching | locking part 10a may be formed. This system ceiling unit B is installed on a steel T-bar 11 assembled in a lattice by dropping from above. When providing the latching | locking part 10a, the latching | locking part 10a can be mounted on the horizontal part of steel-made T-bars 11. FIG.

  The substrate 1 used for forming the system ceiling unit B has a light reflecting / diffusing surface on the surface in the same manner as described above, and is provided with a heat insulating / sound absorbing material 9. And it is the same as in the case of the spandrel A, for example, at least a portion of the ceiling exposed to outside light or an indoor light source.

  The pinholes 4 and 4a drilled in the interior material for lighting according to the present invention have a hole diameter of 0.5 to 1 mm, and are not visible when placed on the ceiling or wall surface. 4, 4a does not impair the appearance, and noise and noise in the room are absorbed from innumerable pinholes 4, 4a, taken into the heat insulation / sound absorbing material 9 above, and muffled. The interior material for lighting according to the present invention is suitable not only for taking in external light, but also as an interior material for public facilities, schools, hospitals, libraries, company conference rooms, and other rooms that need to be silenced. It is a very useful thing which can have nonflammability from the constituent materials.
