Description

  The present invention relates to lighting suitable for a tea room.

In the tea room where the traditional Japanese culture of tea ceremony is held, lighting is devised. In other words, natural light was taken from the window during the daytime, and the illuminance was obtained by the Andon during the night. By directing the natural feeling to the front, it is suitable for the tea ceremony.
In general Japanese-style rooms that are not as strict as tea rooms, indirect lighting is preferred over direct lighting.

  Various types of indirect illumination have been proposed (see, for example, Patent Document 1 (FIG. 8)).

Patent document 1 is demonstrated based on the following figure.
FIG. 10 is a diagram for explaining conventional indirect illumination. An indirect illumination 104 disposed at a corner 103 where the wall surface portion 101 and the ceiling surface portion 102 cross each other includes a light source 105 attached to the corner 103 and the light source. And a light source cover 106 having a substantially L-shaped cross section that covers 105. Illumination (arrow (1)) leaks between the light source cover 106 and the wall surface portion 101 (gap), and illumination (arrow (2)) leaks between the light source cover 106 and the ceiling surface portion 102 (gap). There is no worry that the illumination will directly enter the eyes of the person 107.

The Japanese-style rooms are diverse. In particular, the “Sukiyado-style” Japanese-style rooms that resemble tea rooms use natural bamboo (hereinafter referred to as “natural bamboo sticks”) for the edges and surrounding edges that support the ceiling board. A natural feeling can be strengthened by arranging a natural bamboo stick. Indirect lighting in Patent Document 1 cannot be adopted in such a full-fledged Japanese-style room.
That is, however, since the light source cover 106 protrudes and is conspicuous, the indirect illumination of Patent Document 1 is suitable for the ocean, but is not suitable for a Japanese-style room with a natural bamboo stick.

  Therefore, indirect lighting suitable for a Japanese-style room with a natural bamboo stick is desired.

JP 2005-285664 A

  This invention makes it a subject to provide the illumination suitable for the Japanese-style room which arranged the natural bamboo stick.

The invention according to claim 1 is a Japanese-style room lighting used in combination with a natural bamboo stick delivered to the interior surface of a Japanese-style room,
This Japanese-style room lighting
It is a resin tube having a diameter corresponding to the diameter of the natural bamboo stick and having a C-shaped cross section, and having flexibility and translucency, with a bamboo pattern imitating the natural bamboo stick on the outer surface, An exterior cover supported by natural bamboo sticks;
It consists of a straight tube lamp that is placed in the exterior cover and attached to the interior surface of the Japanese-style room,
The exterior cover is longer than the straight tube lamp.

  The invention according to claim 2 is characterized in that the Japanese-style room is a tea room.

In the device according to claim 1, the illumination is composed of an exterior cover and a straight tube lamp, and the exterior cover is provided with a bamboo pattern. A portion of the natural bamboo stick is cut out and an exterior cover is fitted there.
Since the exterior cover has the same pattern as the natural bamboo sticks at both ends, it is hardly noticed that there is illumination during the daytime (when not lit). That is, despite the presence of lighting, the natural feeling of the Japanese-style room is not impaired.

  At night (when lit), the natural bamboo stick appears to emit light spontaneously. Therefore, despite the presence of lighting, the natural feeling of the Japanese-style room is not impaired.

  Moreover, since the exterior cover is supported by natural bamboo sticks on both sides, the internal straight tube lamp can be freely replaced. That is, even if the straight tube lamp is replaced, it is not necessary to replace the exterior cover, and the exterior cover can be used for a long time.

  In the device according to claim 2, the Japanese-style room is a tea room. By applying the illumination of claim 1 to the tea room, the natural feeling of the tea room is not impaired, and illumination can be obtained.

It is a partial cross section part of a tea room. FIG. 2 is a view taken in the direction of arrow 2 in FIG. 1. It is a disassembled perspective view of the Japanese-style room illumination which concerns on this invention. FIG. 4 is a cross-sectional view taken along line 4-4 of FIG. It is sectional drawing of an exterior cover. FIG. 6 is a sectional view taken along line 6-6 of FIG. It is an effect | action figure of the illumination for Japanese-style rooms. It is a figure which shows the example of a change. It is an effect | action figure of FIG. It is a figure explaining the conventional indirect illumination.

An embodiment of the present invention will be described with reference to the drawings.
In the embodiment, the Japanese-style room with the natural bamboo sticks arranged on the indoor surface will be explained with reference to a tea room. However, the Japanese-style room may be a normal Japanese-style room as long as natural bamboo sticks are arranged on the indoor surface.

  In addition, natural bamboo sticks will be described below by taking the rim as an example, but it may be a peripheral edge, an edge pillar along the sleeve wall, or a stud placed on the wall. If it is a bamboo stick arrange | positioned at an indoor surface, the use is arbitrary. Furthermore, the natural bamboo stick may be arranged away from the ceiling or wall to the indoor side, or may be in close contact with or embedded in the ceiling or wall. In short, the arrangement form is as long as it is arranged along the indoor surface. Be free.

  A part of the tea room 10 will be described with reference to FIG. 1. On the indoor surface 11a of the ceiling 11 of the tea room 10, a plurality of ridges made of natural bamboo sticks 12 are arranged in parallel. A wall 13 rises from the tip of the ceiling 11, and a natural wood 15 is passed to a portion where the wall 13 and the ceiling 11 intersect. A natural bamboo stick 16 containing Japanese-style room lighting is handed over. This natural bamboo stick 16 is also an edge.

As shown in FIG. 2, Japanese-style room lighting 20 is fitted in the middle of the natural bamboo bar 16.
As shown in FIG. 3, the Japanese-style room lighting 20 includes a straight tube lamp 22 fixed to the indoor surface 11 a of the ceiling 11 with screws 21, 21 and an exterior cover 23 that covers the straight tube lamp 22.

The length of the cylindrical portion of the straight tube lamp 22 is L1. The natural bamboo stick 16 is cut out by L2 slightly longer than L1. By being cut out, one natural bamboo stick 16 is divided (separated) into a bamboo stick half 16A and a bamboo stick half 16B.
U-shaped cutouts 24 and 24 are cut out and formed in the side end portion on the split side of the bamboo stick half body 16B. Similarly, U-shaped notches 24 and 24 are formed in the bamboo bar half body 16A. These series of cutting and notching processes are performed on the floor or in an appropriate work place.

The rear U-shaped notch 24 accommodates the fixture 25 for fixing the straight tube lamp 22. The U-shaped notch 24 on the front side is used for inserting a screwdriver when the straight tube lamp 22 is replaced.
The length L3 of the exterior cover 23 is set to a length that allows for further margin by adding the lengths of the U-shaped cutouts 24, 24 to the length L2 of the cutout portion. By setting this length, the straight tube lamp 22 and the U-shaped notches 24 and 24 can be covered.
That is, the exterior cover 23 covers the bamboo bar half body 16A and the bamboo bar half body 16B by δ and δ. δ corresponds to (L3−L2) / 2.

  As shown in FIG. 4, the straight tube lamp 22 includes a heat radiating plate 27 disposed on the wall 13 side, a substrate 28 attached to the heat radiating plate 27, a light emitting diode element 29 mounted on the substrate 28, The glass tube 31 is fixed to the heat dissipation plate 27 so as to surround the light emitting diode element 29. The outer diameter of the glass tube 31 is preferably about 32 mm. The light emitting diode is abbreviated as LED.

  The glass tube 31 is milky white and is mixed or coated with a diffusing agent that diffuses light, and the light generated by the light emitting diode element 29 is diffused by the glass tube 31 and becomes gentle illumination. In this example, the light distribution plates 32 and 32 are set up in the glass tube 31 to control the light distribution.

  In this embodiment, a so-called LED type straight tube lamp 22 is employed. LED lighting has the advantage that the rated life of the light emitting diode element 29 is tens of thousands of hours and the replacement frequency is low. On the other hand, it is expensive.

In the present invention, the straight tube lamp 22 and the outer cover 23 are completely separated, and the straight tube lamp 22 can be easily replaced. Therefore, the straight tube lamp 22 may be a fluorescent tube (a commercially available fluorescent lamp in which mercury vapor is enclosed in a glass tube) that is inexpensive but has a relatively short life.
Therefore, the straight tube lamp 22 may be an elongated cylindrical lamp, and the type and form are arbitrary.

Next, details of the exterior cover 23 will be described.
As shown in FIG. 5, the exterior cover 23 has an elastically deformable translucent resin tube 33 having a thickness tc of 0.3 to 1.0 mm and a C-shaped cross section, and an inner surface of the translucent resin tube 33. An applied diffusing agent 34 and a bamboo pattern 35 printed on the outer surface of the translucent resin tube 33 are applied.
The translucent resin tube 33 having a C shape has a shape in which a portion having a central angle θc of 90 to 100 ° is cut from a circular tube having an inner diameter Dc of 39 mm. In addition to obtaining the translucent resin tube 33 by cutting out the round tube material, it is possible to directly obtain the translucent resin tube 33 exhibiting a C shape by a resin injection molding method. Polycarbonate or acrylic can be used for the translucent resin tube 33.

  If the outer diameter Db of the end portion of the bamboo bar half body 16B is about 40 mm, the bamboo bar half body 16B is not cut. Since the outer cover 23 has a C-shaped cross section and can be elastically deformed, it spreads as shown by an arrow and then fits into the end of the bamboo rod half 16B. Since there is a tightening allowance of 1 mm (39−40 = −1 mm), even if a force is applied due to an earthquake or the like, there is no concern that the outer cover 23 will come off from the bamboo rod half body 16B.

Next, the connection between the exterior cover 23 and the straight tube lamp 22 will be described.
As shown in FIG. 6, the straight tube lamp 22 is fixed to the indoor surface 11 a by a screw 21 through a fixing bracket 25.
On the other hand, as described with reference to FIG. 3, the exterior cover 23 is supported by the bamboo bar half 16A and the bamboo bar half 16B.

Since the straight tube lamp 22 has an outer diameter of 32 mm and the outer cover 23 has an inner diameter of 39 mm, a gap T of about 3.5 mm exists between the two.
Due to the gap T, the illumination of the straight tube lamp 22 is diffused and then diffused by the exterior cover 23 to reach the room. That is, it becomes indirect illumination.

  Further, since there is a gap T, the outer diameter of the straight tube lamp 22 may be changed by about 1.0 mm before and after the replacement. Therefore, the exterior cover 23 can be used and only the straight tube lamp 22 can be replaced.

Next, the operation of the Japanese-style room illumination having the above configuration will be described.
FIG. 7 (a) shows a state when not lit, and FIG. 7 (b) shows a state when lit.
As shown in FIG. 7 (a), the bamboo pattern 35 of the outer cover 23 and the bamboo patterns 35 of the left and right bamboo bar halves 16A and 16B are approximated including the colors when not lit during the daytime. Therefore, the presence of the Japanese-style room lighting 20 is hardly recognized by visitors. That is, it is unlikely that the Japanese room lighting 20 is in the Japanese room, and the natural feeling in the Japanese room is kept good.

  As shown in FIG. 7B, the Japanese-style room lighting 20 emits soft illumination during lighting at night or the like. A part of the natural bamboo stick 16 appears to emit light, which gives the visitor a surprise.

By the way, natural bamboo sticks have different outer diameters, unlike artificial ones. In addition, even in one natural bamboo bar, the base is thick and the tip is thin, and the outer diameter varies depending on the part.
In this case, as shown in FIG. 8, the end portion of the bamboo stick half body 16B is shaved to set the outer diameter to a desired value. If the cutting allowance approximates the thickness of the exterior cover 23, as shown in FIG. 9, it becomes flush and the appearance is further enhanced.

The present invention provides Japanese-style room lighting combined with natural bamboo sticks. It does not apply to plastic artificial bamboo sticks whose outer diameter resembles bamboo. Artificial bamboo sticks made of plastic are inexpensive, but unnaturalness is conspicuous compared to natural bamboo sticks.
The Japanese-style room has a high unit price per square meter, such as making the wall a Kyoto wall. The tea room is even more so. The lighting of the present invention, which is rich in nature, is suitable for such Japanese-style rooms and tea rooms.

  The Japanese-style room lighting of the present invention is suitable for tea room lighting.
