Description

  The present invention relates to an apparatus having a light source.

  Conventionally, a configuration combining a chair and a light-emitting device has been proposed as an example of a device having a light source. For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 9-252875) describes a chair with an electric signboard provided with an electric signboard displayed on the back of the back of the chair (Claim 1, FIG. 1). -4 etc.). Patent Document 1 also describes a configuration in which a light emitter such as a flashlight is incorporated on the back of the chair and the upper surface of the armrest (see claim 5, FIG. 5, etc.).

The light from the second light source is emitted from the end face of the rod-like member.
According to such a configuration, the light emitted from the first light source and reflected in the first region on the side surface of the rod-shaped member is visually recognized as light emission on the side surface of the rod-shaped member, and out of the light from the second light source Light that enters the second region on the side surface of the rod-shaped member and exits from the end surface of the rod-shaped member is visually recognized as light emission from the end surface of the rod-shaped member. Thus, since the light source for emitting light from the side surface of the rod-shaped member and the light source for emitting light from the end surface of the rod-shaped member are different light sources, for example, the side surface and the end surface of the rod-shaped member have different luminances. It is possible to emit light in the form of color, pattern, and the like. As described above, the device according to the first aspect of the present invention can realize light emission of a novel mode.

Moreover, according to the 2nd aspect of this invention, in said apparatus, the 2nd area | region of the side surface of a rod-shaped member is a rough surface. According to this, it is possible to reduce the reflected light and transmitted light in the second region on the side surface of the rod-shaped member, and increase the amount of light emitted from the upper end surface of the rod-shaped member.
Moreover, according to the 3rd aspect of this invention, said apparatus further has a partition plate installed in the boundary of the 1st area | region of a side surface of a rod-shaped member, and a 2nd area | region. According to this, it is possible to avoid mixing the light from the first light source and the light from the second light source, and in particular, the side surface and the end surface of the rod-shaped member have different brightness, color, pattern, and the like. A production effect in the case of emitting light can be enhanced.

  Moreover, according to the 4th aspect of this invention, said apparatus is provided with the some rod-shaped member arrange | positioned in bundle shape. According to this, the light from the first light source is repeatedly reflected by the side surfaces of the plurality of rod-shaped members, and the light from the second light source is emitted from the end surfaces of the plurality of rod-shaped members. Is provided. In this case, according to the fifth aspect of the present invention, the first light source and the second light source are arranged so as to surround the plurality of rod-shaped members, respectively. According to this, it is possible to realize a gradation-like light emission mode in which the outer periphery of a bundle of a plurality of rod-shaped members is brightest and gradually becomes darker as it goes inward.

It is the longitudinal cross-sectional view which looked at the direction of the arrow. As shown in these drawings, the holding device 1 includes a substantially columnar base 10 and a plurality of rod-like members 20 protruding upward from the base 10. The rod-shaped member 20 is made of a transparent resin such as acrylic resin (PMMA resin) or polycarbonate resin (PC resin), or a colorless or colored light-guiding material having translucency such as glass. In the illustrated example, each rod-like member 20 is formed as a cylindrical member.

  The upper surface of the base 10 includes a plate-shaped partition plate 12 and a frame portion 11 that is an annular flat plate member disposed at a position one step higher than the edge portion of the partition plate 12. The base 10 further includes a wall portion that forms a peripheral surface thereof. The partition plate 12 is made of a material such as metal, resin, or wood, and the material itself has a light shielding property, or has a light shielding property by performing a light shielding surface treatment by painting, printing, plating, sputtering, or the like. It has become a thing. A plurality of holes 13 corresponding to the number and cross-sectional shape of the plurality of bar-shaped members 20 are formed in the partition plate 12, and each bar-shaped member 20 is inserted into the hole 13. Thereby, each bar-shaped member 20 is a part that is projected above the partition plate 12 (hereinafter also referred to as “projection part”) and a part that is accommodated in the space inside the base 10 below the partition plate 12. (Hereinafter also referred to as “contained portion”). Each rod-shaped member 20 may be loosely fitted into the corresponding hole 13, may be press-fitted, and may be fixed to the inner peripheral surface of the hole 13 with an adhesive or the like. The some rod-shaped member 20 and the partition plate 12 may be formed integrally.

  In the example shown in FIG. 3A, the positions of the upper ends of the plurality of rod-shaped members 20 are along one virtual plane. As a result, the holding device 1 functions as a chair, bed, sofa, etc. for a person to sit on or sleep on the upper ends of the plurality of rod-shaped members 20, or as a table, shelf, etc. for placing objects. Can function. The present invention is not limited to the configuration in which the positions of the upper ends of the plurality of rod-shaped members 20 are along one virtual plane, and the configuration in which the positions of the upper ends of the plurality of rod-shaped members 20 are along a plurality of virtual planes A configuration along one or a plurality of virtual curved surfaces can also be adopted. In particular, when the holding device 1 is used as a chair, the upper end surfaces of the plurality of rod-like members 20 function as a seating surface as a group, and the upper end portions of the plurality of rod-like members 20 are curved shapes along the human buttocks and thighs. It is preferable to arrange | position so that.

  FIG. 3B is an enlarged partial cross-sectional view showing an enlarged range surrounded by a one-dot chain line IIIB in FIG. FIG. 4 is a partial cross-sectional view of the holding device 1 of FIG. As shown in the figure, the holding device 1 further includes an annular first light source 30 installed on the upper surface near the peripheral edge of the partition plate 12. The 1st light source 30 is arrange | positioned so that the outer periphery of the bundle | flux of the some rod-shaped member 20 may be enclosed. The first light source 30 has a plurality of light emitting portions 31 that are spaced apart from each other in the circumferential direction, and the plurality of light emitting portions 31 emit light toward a bundle of the plurality of rod-shaped members 20. Configured and arranged.

  Each light emitting portion 31 of the first light source 30 emits light to the peripheral surfaces of the protruding portions of the plurality of rod-shaped members 20 by energization. The irradiated light is transmitted through the protruding portions of the plurality of rod-shaped members 20 or reflected on the peripheral surface of the protruding portions, and the light transmitted or reflected in this way passes through the protruding portions of the other rod-shaped members 20. The light is transmitted or reflected on the peripheral surface, and such transmission and reflection of light repeatedly occur in the plurality of rod-shaped members 20. In this way, it is possible to produce an effect of shining the peripheral surface of each rod-like member 20 by light emission from each light emitting portion 31 of the first light source 30. Moreover, since the peripheral surface of each rod-shaped member 20 is visually recognized as light-emitting in this way, the actual number of the rod-shaped members 20 than the light-emitting portions 31 of the first light source 30 is provided. It is possible to produce light that appears to emit light from more light sources than the number of light sources.

  In order to perform light emission of the peripheral surfaces of the plurality of rod-shaped members 20 by the light from the light emitting unit 31 of the first light source 30 more uniformly in the plurality of rod-shaped members 20, the gaps between the rod-shaped members 20 are relatively set. It is preferable to make it narrow. As one index for that purpose, for example, the average value A of the diameters a (see FIG. 3B) of the plurality of rod-shaped members 20 and the length b of the gaps between the plurality of rod-shaped members 20 (FIG. 3 ( It is preferable that the average value B of the reference B) satisfies the relationship B / A ≦ 2.

  FIG. 5 is a partial cross-sectional view of the VV cut surface of the holding device 1 of FIG. As shown in the drawing, the holding device 1 further includes an annular second light source 40 installed on the inner peripheral surface of the base 10 below the partition plate 12. The 2nd light source 40 is arrange | positioned so that the outer periphery of the bundle | flux of the some rod-shaped member 20 may be enclosed. The second light source 40 has a plurality of light emitting portions 41 that are spaced apart from each other in the circumferential direction, and the plurality of light emitting portions 41 emit light toward a bundle of the plurality of rod-shaped members 20. Configured and arranged.

The light emitting portion 41 of the second light source 40 irradiates light to the peripheral surface of the accommodated portion of the rod-shaped member 20 by energization. Part of the light emitted from the light emitting portion 41 of the second light source 40 to the peripheral surface of the accommodated portion of each rod-shaped member 20 enters the inside of each rod-shaped member 20 from the peripheral surface of the rod-shaped member 20 and enters. A part of the light is reflected by the inner surface of the rod-shaped member 20 and emitted from the upper end surface of the rod-shaped member 20 to the outside. In this way, the light emitted from the light emitting unit 41 of the second light source 40 emits the upper end surfaces of the plurality of rod-shaped members 20, and the upper end surfaces of the plurality of rod-shaped members 20 emit light in a dotted manner as a whole. be able to. Since the upper end surface of each rod-shaped member 20 is visually recognized as emitting light, by providing more rod-shaped members 20 than the light-emitting portions 41 of the second light source 40, the actual number of light-emitting portions 41 is exceeded. It is possible to produce light that appears to emit light from many light sources. By performing the process of making the lower end surface of the rod-shaped member 20 white, the visibility of light emission from the upper end surface of the rod-shaped member 20 can be enhanced. In place of or in addition to the process of making the lower end surface of the rod-shaped member 20 white, the same effect can be obtained even if the portion or surface of the other member that contacts or faces the lower end surface of the rod-shaped member 20 is white.
Each rod-like member 20 has a blasting treatment, a matte clear coating, a mending tape, etc. on the peripheral surface of the portion to be accommodated (the peripheral surface within the range indicated by the double-headed arrow “a” in FIG. 3B). The roughening process is performed. Therefore, it is possible to reduce the reflected light and transmitted light on the peripheral surface of the accommodated portion of the rod-shaped member 20 as the light incident surface, and increase the amount of light emitted from the upper end surface of the rod-shaped member 20.

  Thus, the 1st light source 30 for light-emitting the peripheral surface of the protrusion part of the rod-shaped member 20, and the 2nd light source 40 for light-emitting the upper end surface of the rod-shaped member 20 are another light sources. Thus, for example, the peripheral surface and the upper end surface of the rod-shaped member 20 can be made to emit light in different brightness, color, pattern, and the like. For this purpose, the light emission portions 31 of the first light source 30 and the light emission portions 41 of the second light source 40 may have different light emission, color, pattern, and other aspects. You may change the light emission mode of at least one of the light emission part 31 of the 1st light source 30, and the light emission part 41 of the 2nd light source 40 with progress of time. You may vary the aspect of light emission between the some light emission parts 31 and 41 of the 1st and 2nd light sources 30 and 40. FIG. The mode of light emission of the plurality of light emitting portions 31 and 41 of the first and second light sources 30 and 40 may be changed according to the load applied to the rod-like member 20 by using a load sensor or the like.

The light emitting unit 31 of the first light source 30 and the light emitting unit 41 of the second light source 40 may be light emitting elements such as LEDs and organic ELs, and may be fluorescent lamps, incandescent light bulbs, and the like. Absent. The first light source 30 and the second light source 40 may be linear light sources that emit light around their entire circumference, or only the inner circumference side of the entire circumference may emit light linearly. Instead of using the annular first light source 30, only the plurality of light emitting units 31 may be directly attached to the partition plate 12. Similarly, instead of using the annular second light source 40, only the plurality of light emitting units 41 may be directly attached to the inner surface of the base 10.
The positions and number of the light emitting units 31 of the first light source 30 and the light emitting units 41 of the second light source 40 may be different from each other. The interval between the light emitting units 31 of the first light source 30 and the interval between the light emitting units 41 of the second light source 40 may not be constant.
The power supply and the control circuit for causing the light emitting unit 31 of the first light source 30 and the light emitting unit 41 of the second light source 40 to emit light are not shown.

In that case, the installation direction of the holding device 1 is arbitrary, such as horizontally placed or upside down. Furthermore, the device according to the present invention can be realized not only as a single holding device 1 but also as a part of another product such as an automobile seat.

The upper surface and side surfaces of the frame portion 11 and the upper surface of the partition plate 12 may be mirror surfaces. The reflection of light by the mirror surface enables the production of deeper light.
The partition plate 12 may be a transparent member or may be omitted. However, in the case where the partition plate 12 has a light shielding property, there is an advantage that the light of the first light source 30 and the light of the second light source 40 can be prevented from being mixed. It is possible to enhance the production effect when the end faces are made to shine with different brightness, color, pattern, and the like.

(Comparative example)
FIG. 11 is a longitudinal sectional view of a holding device 100 according to a comparative example of the present invention, and corresponds to FIG. 3 of the first embodiment. Instead of the first light source 30 and the second light source 40 of the first embodiment, the holding device 100 shown in FIG. 11 has a plurality of light sources 200 respectively disposed below the lower ends of the respective rod-shaped members 20. In the holding device 100 of the comparative example having such a configuration, light from the light source 200 is taken in from the lower end surface of the rod-shaped member 20 and the taken light is emitted from the upper end surface of the rod-shaped member 20.
In the holding device 100 of the comparative example, when a downward load is applied to the upper ends of the plurality of rod-shaped members 20, the influence of the load may be transmitted from the lower ends of the rod-shaped members 20 to the light source 200. It may lead to damage. In contrast, in the holding devices 1, 1 </ b> A to 1 </ b> D according to the embodiments of the present invention, such a problem occurs because the light sources 30, 40 for the rod-shaped member 20 are not arranged below the lower end of the rod-shaped member 20. Absent.

In the comparative example, when light incident on the lower end surface of the rod-shaped member 20 from the light source 200 is emitted from not only the upper end surface of the rod-shaped member 20 but also the peripheral surface of the protruding portion, the peripheral surface of the protruding portion is roughened. It is necessary to process it. In contrast, in the holding devices 1, 1 </ b> A to 1 </ b> D according to the embodiments of the present invention, the first light source 30 that irradiates light to the peripheral surface of the protruding portion of the rod-shaped member 20 is provided. There is no need to roughen the peripheral surface.
Further, in the configuration in which the light sources 200 for direct incidence of light on each of the plurality of rod-shaped members 20 are prepared as in the comparative example illustrated in FIG. 11, the number of light sources 200 to be prepared according to the number of the rod-shaped members 20. This is disadvantageous from the viewpoint of manufacturing and cost.
