Description

  The present invention relates to a lighting device that can be constructed on a building material.

  Conventionally, on stairs installed in a building such as a house or an outdoor facility, an accident has occurred when the lighting is not turned on or at night. The cause of this accident is that the feet of stairs users are relatively dark, making it difficult for the users to visually recognize the stairs. For this reason, various lighting devices for stairs are known so that the user does not step on the tread board when moving up and down the stairs.

  For example, Patent Document 1 discloses a lighting device for a staircase that improves the visibility of a stair tread. This lighting device includes a linear light emitting portion embedded in a state where an upper surface is exposed in a horizontal groove formed on the upper surface side of the front end portion of the tread plate, and a tread plate that is continuous and curved in a curved shape to the linear light emitting portion. And a light guide portion whose end portion protrudes from the back surface of the tread board. According to this configuration, the light reflection / diffusion area is selectively provided in the linear light-emitting part serving as the light-emitting part instead of the entire light guide rod, so that the light guide efficiency is improved and light enters the light reflection / diffusion area. concentrate. Moreover, the light loss can be suppressed by curving the light guide portion, which is a path to the linear light emitting portion, in a curved shape. Together, these actions improve the light extraction rate and provide a high lighting effect.

  Further, as another lighting device for stairs, Patent Document 2 discloses a decorative board material. The decorative board material includes a tread board, a hard synthetic resin molded body that covers the front end portion of the tread board and is attached so as to form a space portion with the front end portion (simply described as a molded body), and the interior of the space portion. And a light emitter disposed on the surface. According to this configuration, the luminous body can be visually recognized from below, and the user of the staircase does not feel uncomfortable because it is too bright. In addition, since the protruding portion that protrudes from the upper half of the rear end surface of the molded body is placed on the stepped portion that protrudes from the lower half of the front end surface of the plate body, even if a load is applied to the molded body, It is hard to fall off from the body and the illuminant is protected.

However, in the illuminating device described in Patent Document 1, since the light guide bar is embedded in the step board of the staircase and the light emission surface is in one direction, the light emission from the lower stage to the upper stage is particularly difficult to see, and the visibility of the tread board is high. There remains a problem of decline.
In order to solve the above problem, it is conceivable to expose the light guide member on the surface of the step board and emit light from the light guide member in all directions. However, in that case, the light guide member is damaged by an impact from the outside of the lighting device, such as the user directly stepping on or kicking the light guide member, or the user touches the light guide member. There is a problem that the impact resistance of the lighting device is reduced. In view of this problem, in the illumination device described in Patent Document 2, the light guide member (light emitting body) is protected by being covered with a molded body.

  However, in any of the lighting devices described in Patent Document 1 and Patent Document 2, when constructing a staircase, a groove is formed on the tread surface of the staircase, or a tread plate provided with a light guide member and a molded body is replaced. There is a problem that large-scale construction and work are required.

At this time, light is emitted in all directions from the side surface of the light guide member to the outside. The light emitted from the light guide member is emitted toward the outside of the lighting device through the protective member made of transparent resin, and can be visually recognized. In this way, the light guide member is provided on the surface of the building material, and the light from the light source is emitted in almost all directions from the side surface of the light guide member, thereby increasing the visibility of the building material.
Further, according to the above configuration, since the protective member covers the light guide member so as not to be exposed, even if an impact is applied to the light guide member from the outside of the lighting device, the impact is moderately applied by the protective member. Absorbed. Therefore, damage to the light guide member is suppressed, and the impact resistance of the lighting device is increased.

  Moreover, in the illuminating device of this invention, it is preferable that the said protection member consists of soft transparent resin.

  According to the above configuration, since the protective member that is susceptible to an impact from the outside of the lighting device is made of a soft transparent resin, the received impact is further absorbed by the protective member, and the impact resistance of the lighting device is improved. Get higher.

  Moreover, in the illuminating device of this invention, it is preferable that the space | gap is provided between the said light guide member and the said protection member.

  According to said structure, the impact from the exterior of an illuminating device is absorbed more by a space | gap, and the impact resistance of an illuminating device becomes higher.

  Moreover, in the illuminating device of this invention, it is preferable that the support part which consists of protrusion which supports the said light guide member is provided in the inner surface of the said protection member.

  According to said structure, since a light guide member is supported by the support part in the hollow part between a protection member and a base material, the attitude | position of a light guide member becomes more stable and the visibility of building materials becomes high.

  Moreover, in the illuminating device of this invention, it is preferable that the reflection layer is provided between the said light guide member and the said base material.

  According to the above configuration, out of the light emitted in all directions in the cross-sectional view from the side surface of the light guide member, the light in the direction toward the base material is reflected by the reflective layer, and the traveling direction is It is emitted toward the outside of the light guide member. Therefore, the visibility of the building material is further enhanced by almost completely releasing light from the side surface of the light guide member to the outside of the lighting device.

  Further, in the lighting device of the present invention, the lighting device is constructed on a staircase, the base material is refracted along the corner of the staircase, and the light guide member is formed on the surface of the base material. Among them, the non-slip member is arranged on the portion located on the upper end of the kick plate when constructed on the staircase, and on the portion of the surface of the base material located on the tread plate when constructed on the staircase.

It is a perspective view which shows the illuminating device concerning one Embodiment of this invention. It is a figure which shows the illuminating device concerning one Embodiment of this invention, Comprising: It is sectional drawing corresponding to the case where it views on the CC 'line | wire shown in FIG.

  An illumination device according to an embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a perspective view showing a lighting device 1 of the present embodiment. FIG. 2 is a diagram illustrating the lighting device 1 and is a cross-sectional view corresponding to the case of viewing along the line CC ′ illustrated in FIG. 1.

The illuminating device 10 of this embodiment is constructed on the surface of a building material in order to make a user visually recognize the presence of the building material and brighten his feet. Below, it demonstrates supposing the tread T and the kick board U of the staircase S shown in FIG. 1 as building materials.
As shown in FIGS. 1 and 2, the lighting device 1 includes a base material 12, a light source 10, a light guide member 14, and a protection member 20. Moreover, the illuminating device 1 is provided with the anti-slip | skid member 22, and also serves as what is called a non-slip thing for a user not to slip | slip a leg | foot.

The base material 12 is a long member formed in accordance with the position where the lighting device 1 is constructed. In this embodiment, the base material 12 is a member formed so as to extend in the longitudinal direction (that is, the D direction) of the step board T, the kick board U (building material) of the staircase S shown in FIG. It is.
Moreover, the base material 12 is formed to have a cross-sectional shape that is refracted along the corner A of the step S, as shown in FIG.

  A gap R is provided between the base material 12 and the kick plate U of the staircase S. When an impact is applied from the outside of the illumination device 1 toward the kick plate U, the impact is absorbed to some extent by the gap R. Therefore, the cross-sectional shape of the base material 12 and the size of the gap R are preferably set in consideration of the magnitude of impact applied to the lighting device 1 and the like.

  The base material 12 is formed from resin, such as hard vinyl chloride (PVC), polyethylene, a polypropylene, an ABS resin, for example. For example, for the purpose of improving aesthetics, a material obtained by mixing other components with a resin-based material may be used as the material of the substrate 12.

A non-slip member 22 is attached to a portion of the surface 12 a of the base material 12 that is located on the tread board T when the lighting device 1 is applied to the staircase S. As shown in FIG. 2, the anti-slip member 22 has a bellows-like cross section in the longitudinal direction (D direction) of the lighting device 1 and is so-called formed to extend in the D direction along the substrate 12. It is a corrugated member. By providing the anti-slip member 22 in this way, the anti-slip effect of the lighting device 1 as non-slip is further enhanced. For the purpose of improving the anti-slip effect, the anti-slip member 22 is made of a resin such as soft vinyl chloride (SPVC), acrylic elastomer, ethylene elastomer, styrene elastomer.
It should be noted that if the anti-skid effect of the lighting device 1 is sufficiently obtained without attaching the anti-slip member 22 to the base material 12, or if the high anti-skid effect is not required for the lighting device 1, etc. The stop member 22 can be omitted.

  On the back surface 12 b of the base material 12, an adhesive 28 is attached for bonding the lighting device 1 and the step board T of the staircase S when the lighting device 1 is applied to the staircase S constructed in advance. For example, a double-sided tape may be used as the adhesive 28, but is not particularly limited to the double-sided tape.

The light source 10 is for emitting light from the lighting device 1, and is specifically a light emitting diode (LED), a miniature light bulb or the like. As shown in FIG. 1, the light source 10 is accommodated in a light source unit 50 disposed at one end 12 c of the base 12. In addition to the light source 10, the light source unit 50 houses a power source for causing the light source 10 to emit light, a sensor for detecting the presence or absence of a user who moves up and down the stairs S (hereinafter simply referred to as a user), and the like. It may be.
If the light source 10 is installed only at one end 12c of the base 12 such as when the longitudinal dimension of the tread T and the kick plate U of the stair S is sufficiently large, the light source It is preferable to place 10 on the other end 12d of the base material 12 and install it at both ends.

  The light guide member 14 is a rod-shaped member that is provided on the surface 12 a of the base 12 and emits side light. The “bar shape” means that the shape is long along the shape of the substrate 12. In the present embodiment, as shown in FIG. 2, the light guide member 14 is formed on a portion of the surface 12 a of the base material 12 that is positioned at the upper end of the kick plate U when the lighting device 1 is constructed on the stairs S. Is provided.

As shown in FIG. 2, the light guide member 14 is formed to include a core portion 16 and a clad portion 17 provided so as to surround the core portion 16 in a sectional view, and guided light is transmitted from the core portion 16. It is a so-called side-emitting fiber configured to scatter.
The core portion 16 is connected to an emission surface (not shown) of the light source 10 so that light emitted from the light source 10 can enter inside. For example, the core portion 16 is made of a resin having a refractive index of 1.45 to 1.60. The clad portion 17 is formed of a resin having a refractive index of 1.35 to 1.45, which is lower than that of the core portion 16. However, both materials may be selected so that the refractive index difference between the core portion 16 and the clad portion 17 is 0.01 to 0.15, and the refractive indexes of the core portion 16 and the clad portion 17 are within the above ranges. It is not limited to.
In addition, when manufacturing the light guide member 14 by extrusion molding, a suitable material for the core portion 16 is an acrylic resin having a molding temperature of 190 to 250 ° C. Among them, for example, polymethyl methacrylate resin (PMMA) Is mentioned. Moreover, as a suitable material of the clad part 17, there is a fluorine resin having a molding temperature of 230 to 300 ° C. Among them, for example, a copolymer (EFEP) of hexafluoropropylene, tetrafluoroethylene, and ethylene, ethylene, and the like. A copolymer of tetrafluoroethylene (ETFE) may be mentioned.

  Of the side surface of the light guide member 14, a portion exposed from the base material 12 is formed so as to protrude from the base material 12 and bend in a cross-sectional view in the D direction. Since the light guide member 14 is formed in such a shape, the light scattered from the core portion 16 is efficiently emitted in the direction of the arrow E5 shown in FIG.

  A reflective layer 18 is provided between the light guide member 14 and the substrate 12. The reflection layer 18 deflects the light emitted from the side surface of the light guide member 14 in the direction toward the substrate 12, that is, in the direction of arrow E <b> 2 shown in FIG. 2, and toward the outside of the illumination device 1. That is, it is for discharging in the direction of arrow E3 shown in FIG. The reflective layer 18 may be, for example, the same resin as that constituting the clad part 17, or may be one in which 1.5 parts by weight of titanium dioxide is added to 100 parts by weight of the base resin. A dielectric multilayer film may be used, but is not particularly limited thereto.

The light guide member 14 of the present embodiment is formed in a semicircular shape in cross-sectional view. Since the light guide member 14 is formed in a semicircular shape, the light guide member 14 does not protrude when the lighting device 1 is installed on the staircase S, compared to the case where the light guide member 14 is formed in a circular shape or other shapes. The light reflected by the reflective layer 18 is emitted more uniformly toward the outside of the lighting device 1, and the contact area between the light guide member 14 and the substrate 12 is increased.
For the purpose of directing light emitted from the light guide member 14 upward, the shape of the base material 12 on which the light guide member 14 is provided is such that when the lighting device 1 is applied to the stairs S, the light guide is formed. The contact surface between the member 14 and the base material 12 is set so as to be separated from the kick plate U as it goes downward.

  The protection member 20 is a member that covers the light guide member 14 so as not to be exposed. The protection member 20 is formed from a transparent resin. Therefore, the light emitted from the light guide member 14 is visible to the user of the stairs S without being blocked by the protection member 20. Even if an impact is applied from the outside of the lighting device 1 toward the light guide member 14, the impact is appropriately absorbed by the protection member 20.

  From the viewpoint of further improving the impact resistance of the lighting device 1, the protective member 20 is preferably formed of a soft transparent resin, that is, a thermoplastic resin. Here, the “soft” indicates that the durometer hardness (JIS K 6253-3) is A30 or more and A90 or less. Moreover, the protection member 20 is formed from the soft transparent resin whose durometer hardness is A30 or more and A85 or less from the point which improves the impact resistance of the illuminating device 1 by the protection member 20, and maintains the intensity | strength of the protection member 20. It is more preferable. In this way, if the protective member 20 that easily receives an impact from the outside of the lighting device 1 is made of a soft transparent resin, the received impact is further absorbed by the protective member 20 and is not transmitted to the light guide member 14. A suitable transparent resin constituting the protective member 20 is, for example, an acrylic elastomer because it can be manufactured by extrusion molding simultaneously with the base material 12 made of a vinyl chloride resin and the anti-slip member 22.

  A gap 26 is provided between the light guide member 14 and the protection member 20. By the air gap 26, the impact from the outside of the lighting device 1 is further absorbed. Moreover, the base material 12, the antiskid member 22, and the protection member 20 are manufactured by simultaneous extrusion molding, and the light guide member 14 is manufactured separately from the extrusion molding, and the light guide member 14 is formed of the base material 12 and the protection member 20. When inserted into the enclosed hollow part, the light guide member 14 is easily inserted by the gap 26. Therefore, the size of the gap 26 may be set in consideration of the impact resistance of the lighting device 1, the manufacturing method of the lighting device 1, which will be described later, the efficiency of the manufacturing work, and the like.

  A support portion 20 </ b> D made of a protrusion is provided on the inner surface of the protection member 20. The front end of the support portion 20 </ b> D is formed so as to be able to contact the light guide member 14. In the present embodiment, the support portion 20 </ b> D has a cross section that protrudes toward the light guide member 14 in the D direction, and is formed in a convex shape so as to extend in the D direction along the light guide member 14. As long as the light guide member 14 can be supported, the support portion 20 </ b> D is not limited to the above form, and may be formed as a plurality of convex shapes and randomly disposed on the inner surface of the protection member 20.

  Then, the manufacturing method of the illuminating device 1 and the construction method to the staircase S are demonstrated. Below, it demonstrates supposing manufacturing the base material 12, the light guide member 14, the protection member 20, and the antiskid member 22 by simultaneous extrusion molding.

METABLEN (registered trademark) W-377 (manufactured by Mitsubishi Rayon Co., Ltd.) can be mentioned. These materials are supplied to an extruder for each material of the extrusion molding apparatus, and heated and melted at a temperature equal to or higher than the melting point of each material. Thereafter, the respective materials are extruded from the extruder into a predetermined shape shown in FIGS. 1 and 2, merged, and integrally molded. Further, the molded base material 12, the anti-slip member 22 and the protective member 20 are passed through a cooler of an extrusion molding apparatus so as to be compliant with each other. In addition, the adhesive 28 is attached to the back surface 12 b of the substrate 12.

  Next, similarly, using a known extrusion molding apparatus (not shown), the core part 16, the clad part 17, and the reflection layer 18 of the light guide member 14 are relatively close to each other although the molding temperature is significantly different from that of the base material 12 and the like. Prepare the materials. In the same procedure as described above, the rod-shaped light guide member 14 and the reflective layer 18 are integrally formed using an extrusion molding apparatus.

Next, the rod-shaped light guide member 14 and the reflection layer 18 that are integrally formed are inserted into the hollow portion surrounded by the protection member 20 and the substrate 12 so that the reflection layer 18 is in contact with the substrate 12. . If necessary, an adhesive may be applied to the surface of the reflective layer 18 on the substrate 12 side.
Thereafter, a light source unit 50 containing the light source 10 is prepared, and the light emitted from the light source 10 can enter the core portion 16 of the light guide member 14, and the light source unit 50 is attached to the one end 12 c of the substrate 12. Installing.

The light emitted from the light guide member 14 is emitted toward the outside of the lighting device 1 through the protective member 20 made of a transparent resin, and is visible. In this way, the light guide member 14 is not embedded in the stairs S, but is provided on the surface of the tread board T or the kick board U, so that the light from the light source 10 is almost omnidirectional from the side surface of the light guide member 14. By releasing, the visibility of the tread board T and the kick board U is enhanced.
Further, according to the above configuration, since the protection member 20 covers the light guide member 14 so as not to be exposed, an impact is applied from the outside of the lighting device 1 due to a user's foot hitting the light guide member 14 or the like. Even if applied, the impact is appropriately absorbed by the protective member 20. Therefore, damage to the light guide member 14 is suppressed, and the impact resistance of the lighting device 1 is improved.

In addition, when the light guide member 14 and the base material 12, the protection member 20, and other components of the lighting device 1 are separately molded by a method such as coextrusion molding, a gap 26 is provided. Thus, the light guide member 14 is smoothly inserted into the hollow portion surrounded by the protective member 20 and the base material 12 after molding. Therefore, the working efficiency in the manufacturing process of the lighting device 1 can be improved.

Moreover, in the illuminating device 1 of this embodiment, it is preferable that support part 20D which consists of protrusion which supports the light guide member 14 is provided in the inner surface of the protection member 20. FIG.
According to the above configuration, since the light guide member 14 is supported by the support portion 20D in the hollow portion surrounded by the protective member 20 and the base material 12, the posture of the light guide member 14 is further stabilized, and the tread board T and the kick plate The visibility of the embedded plate U is improved.
