Description

  The present invention relates to an electric decoration device, and more particularly, to an electric decoration device that uses a light emitting diode lamp (hereinafter also referred to as an LED lamp) to enhance an electric decoration effect such as a flooring material, a wall material, and a ceiling material.

A conventional lighting device includes a floor lighting device. This is because the floor lighting of a building such as an amusement store is equipped with a lighting device that gives the effect of the lighting to the entire space in the building so that the entire space can be visually raised and raised. In order to provide a decoration device, a frame body is placed on the floor of a building, a translucent plate is placed on the frame body, and the light source accommodation space surrounded by the floor of the building, the frame body, and the translucent plate There is one in which a light source is placed and blinking of the light source is controlled by a control device (Patent Document 1).
In addition, it is an electrical decoration device that uses an electroluminescence sheet, and even if the installation space is narrower than before, it is okay and installation work for installation is simple. Since it does not appear to protrude from the surface to be installed, there is no sense of incongruity, and the decoration effect is further improved. Therefore, to provide an electric decoration device whose application range is much improved than before, the emission light side surface of the electroluminescence sheet In addition, there is an electrical decoration device provided with translucent expression means (Patent Document 2).
In addition, a box body with an inner surface formed as a reflective surface to make the planar light source for backlights such as liquid crystal display devices and electric signboards lightweight, less light loss, thin, uniform in brightness, and inexpensive. And a linear light source built in the box, and a plurality of light transmission regions are provided uniformly on one wall surface of the box, and as the distance from the linear light source increases, the light transmission region There is one that is provided so that the ratio to one wall surface is increased, and the light from the linear light source is emitted from the wall surface (Patent Document 3).

  However, the light emission sources of the conventional electric decoration devices of Patent Documents 1 to 3 are planar or linear, and the electric decoration effect is rough. Patent Document 4 has a structure in which a point light source is embedded in concrete. However, since the structure is embedded in concrete, repair and maintenance of the light emitter are very troublesome. In addition, dust may accumulate in the holes and the electrical decoration effect may be reduced. In addition, the design must take into account the expansion and compression of concrete due to heat.

More specifically, it is conceivable to attach an LED lamp to a base material (for example, a hollow wood composite material) to enhance the electric decoration effect. It is conceivable to embed an LED lamp by making a small hole on the front surface and a large hole on the back surface of the base material in the vertical direction. The light from the LED lamp is radiated to the outside through the small hole. On the other hand, it is conceivable to inject urethane from a large hole on the back surface, or to fix the large hole by inserting a cap, or to fix them in combination.
However, there are actually various problems. One is that it takes much time to connect the LED lamps. Before the LED lamp is embedded in the base material, the LED wiring must be soldered to the connection wiring, and then the LED lamp must be dropped and fixed with urethane. In addition, there are major problems of labor and loss for injecting urethane. In particular, the reliability of the product is low because you have to wait until the urethane hardens. There is also a risk that the LED lamp may be removed during the work. Furthermore, when it is desired to replace the LED lamp later, the replacement is impossible, so the maintainability is poor. There is a problem of workability that there is a special tool because it is difficult to work on site or it is difficult to make a large hole. There is a problem with supplying such products in the market as products.

  An object of the present invention is to improve the workability of attaching an LED lamp to a base material and improve the maintainability.

  In order to solve the above-mentioned problems, the invention according to claim 1 is larger than the hole for light emitting die auto lighting formed through in the normal direction of the front surface and the hole for light emitting die auto lighting formed through in the normal direction of the back surface. A light emitting die auto insertion hole with a diameter, a base material having a hollow portion formed in a lateral direction, and a lead wire groove for sandwiching a lead wire of a light emitting diode lamp are formed on the upper side in the axial direction, and a power cable is sandwiched A power cable groove is formed on the upper side in a direction intersecting the axial direction, and a shaft-like member inserted into the light emitting die auto insertion hole, and the power cable is sandwiched between the power cable grooves, and the lead The lead wire and the power cable are fixed to the shaft-shaped member by sandwiching the wire in the lead wire groove and pressing the power cable from above with the lead wire. A illumination device according to claim.

The electric decoration device according to claim 1, wherein the lead wire is pressed and fixed by the elastic annular member by fitting the member. It is preferable that the upper surface of the light emitting diode lamp lighting hole and the upper surface of the light emitting portion are flush with each other, but some tolerance is allowed as long as it is visible from above.

  This electric decoration device includes application to floor materials, wall materials, ceiling materials, pillar materials, and the like. Moreover, it is applicable regardless of whether it is outdoors or indoors.

The interior of the base material, for example, the hollow wood composite material, is a hollow shape divided by a partition plate, but the strength of the base material is also improved by filling the hollow part with urethane foam, etc. It is processed into a woody synthetic material that can withstand use as a member.
Here, the number of partition plates formed inside the base material is preferably at least two or more.

  An example of the base material here is a hollow woody synthetic board, which is preferably molded from a mixture of wood flour and thermoplastic resin. Particularly preferred are general-purpose plastics (polyolefin, polystyrene resin, methacrylic resin, polyvinyl chloride, etc.), engineering plastics (polyamide, polycarbonate, saturated polyester, polyacetal, etc.) and the like. For example, it is preferably made of a thermoplastic elastomer such as polyethylene (hereinafter referred to as PE), polypropylene (hereinafter referred to as PP) or nylon. Any kind of wood flour is acceptable. A reinforcing agent (maleic anhydride-modified polypropylene (eg Sanyo Chemical Industries, Ltd. Yumex 1010) etc.) may be mixed at about several percent or less (for example, 0.5%).

  The LED lamp can be fixed to the base material in a short time due to the electric decoration effect of the inventions of claims 1 and 2, and the workability is good. LED lamps that are available to anyone in the general market can be used. It is easy to replace the LED lamp. Field work is easy. It is possible to illuminate only on one side of the base material, and it is possible to obtain an effect on both sides.

In addition, the LED lamp 2 includes a light emitting unit 12 having an upper surface 11 disposed so as to be flush with the upper surface 8 a of the LED lamp lighting hole 8, and a holding unit 13 including a lens that wraps the light emitting unit 12. ing. The LED lamp 2 is inserted from the LED lamp insertion hole 9 to insert and fix the light emitting portion 12 in the LED lamp lighting hole 8. Further, a shaft-like member 17 for attaching the lower portion 16 of the holding portion 13 by attaching an LED lead wire 15 extending from the LED lamp 2 and wired in the hollow portion 7 is provided. Details will be described below.

  As shown in FIGS. 5 to 8, the shaft-like member 17 has a substantially cylindrical shape, and has two lead wire grooves 18 that sandwich the LED lead wires 15 on the upper side in the axial direction. The two lead wire grooves 18 correspond to the plus terminal and the minus terminal of the LED lead wire 15, respectively. The two lead wire grooves 18 are respectively provided on opposite surfaces (180 degrees, different surfaces) of the shaft-like member 17. Further, two power cable grooves 20 are formed on the upper side in a direction (horizontal direction) orthogonal to the axial direction, which intersects with the lead wire grooves 18 and sandwiches the power cable 19. The two power cable grooves 20 correspond to the positive power line and the negative power line of the power cable 19, respectively. The two power cable grooves 20 are formed at different heights, and are provided on opposite surfaces (180 degrees, different surfaces) of the shaft-like member 17. The power cable 19 is sandwiched in the power cable groove 20, the LED lead wire 15 is sandwiched in the lead wire groove 18, and the LED lead wire 15 presses the power cable 19 from above. The shaft 19 is fixed to the shaft-like member 17 while being kept in contact. When viewed in cross section, the groove width of the lead wire groove 18 is reduced as it approaches the center, so that until the middle of the groove, the surface of the lead wire groove 18 is inclined so that the groove width is reduced. It has become. When viewed in a longitudinal section, the groove width of the power cable groove 20 is reduced as it approaches the center, so that the surface of the power cable groove 20 is inclined so that the groove width is reduced to the middle of the groove. It has become. The upper outer diameter of the shaft-like member 17 increases toward the lower side. The lower part of the LED lamp 2 is seated on the upper surface 21 of the shaft-like member 17. The diameter of the lower part of the shaft-like member 17 is preferably 8 to 10 mm. As shown in FIG. 7, the axial protrusions 22 are formed on the surface of the shaft-like member 17 with a predetermined gap or an arbitrary gap in the axial direction, and the entire surface has an uneven shape. This becomes the caulking and fulfills the function of packing. The protrusion height of the axial protrusion 22 is preferably 0.1 to 0.4 mm from the viewpoint of ensuring workability of insertion / removal. The tip of the LED lead wire 15 may be further extended and curved or bent, which is effective for preventing the drop. The bottom surface of the shaft-shaped member 17 is a horizontal circular surface 23. Although not shown, the lead wire groove 18 is reduced as the groove width goes downward. Thereby, the force with which the LED lead wire 15 presses the power cable 19 is increased.

  The hollow woody synthetic material 3 has a small coefficient of linear expansion due to heat as compared with wood and metal, but the linear expansion in the vertical direction tends to be larger than that in the horizontal direction. Although depending on the material, when the hollow wooden synthetic material 3 expands and contracts, the upper end portion of the shaft-like member 17 may follow the expansion and contraction and may not be easily removed from the hole.

  In FIG. 3, the light emission direction is unidirectional, but a configuration in which the positions of the LED lamp lighting hole 8 and the LED lamp insertion hole 9 are reversed can be added.

  Further, if the hollow wood composite material 3 and the shaft-like member 17 are made of the same material, the back surface of the hollow wood composite material 3 can be obtained by polishing the shaft-like member 17 with an abrasive such as a sander after the LED lamp 2 is embedded. The lower surface of the shaft-like member 17 is flush with each other, and the seam can be made unobtrusive.

  The installation work of the lighting device 1 (on-site enforcement type) will be described. An LED lamp lighting hole 8 is opened in the front plate portion 4 of the hollow wood composite material 3 with an electric tool, and an LED lamp insertion hole 9 having a diameter larger than that of the LED lamp lighting hole 8 is opened in the back plate portion 5. The holes may be formed in advance at the factory. The power cable 19 is sandwiched between the power cable grooves 20. The LED lead wire 15 is inserted into the lead wire groove 18 from above. Then, the LED lamp 2 is inserted into the LED lamp insertion hole 9 from the upper surface 11, the lower part of the shaft-like member 17 is fitted into the LED lamp insertion hole 9, and the upper surface 11 is accommodated in the LED lamp lighting hole 8. Plug in. The hollow portion 7 of the hollow wooden synthetic material 3 is used as a wiring storage place. A connector 21 is attached to the LED lead wires 15 that are exposed at both ends of the hollow portion 7. The power cable 20, the connector 21 and the like may be accommodated in the hollow portion 7 for improving the appearance. Further, a controller that performs control such as blinking the LED lamp 2 may be incorporated in the hollow portion 7. In some cases, the LED lamp 2 is replaced due to a change or breakage of the emission color of the LED lamp 2.

  According to the electrical decoration device 1 of Embodiment 1 described above, the LED lamp 2 can be fixed to the hollow wood composite material 3 in a short time by a one-touch type mounting operation, so that the factory productivity is improved and the on-site workability is good. It is. Furthermore, quality stability and maintainability can be ensured. Since the mold for the shaft-shaped member 17 is easy to make and easy to mold, product stability is enhanced. The LED lamp 2 available to anyone in the general market can be used. The LED lamp 2 can be easily replaced. The installation work of the LED lamp 2 on site is easy. Rather than fixing the LED lamp 2 to the hollow wood composite material 3 with an adhesive such as urethane foam, the LED lamp insertion hole 9 can be made smaller, specifically, 30 mm can be reduced to about 7 to 10 mm. It becomes unnecessary. If the shaft-like member 17 is injection-molded, it can be manufactured very efficiently and the cost can be reduced. Depending on how to open the LED lamp lighting hole 8 and the LED lamp insertion hole 9, only one side can be illuminated, and both sides can be illuminated, thus increasing the degree of design freedom.
