Description

本考案は光拡散シートとＬＥＤを使用した、間接照明器具である。The present invention is an indirect lighting apparatus using a light diffusion sheet and LEDs.

従来白熱灯蛍光灯などを用いた直接照明があった、間接照明としては行灯や提灯などが昔からあるが光源はやはり白熱灯や蛍光灯であった。Conventionally, there has been direct lighting using incandescent fluorescent lamps, etc., but indirect lighting has traditionally been lanterns and lanterns, but the light source was still incandescent lamps and fluorescent lamps.

白熱球を用いたものは内部に熱がこもり熱くなるなどの問題があった、また白熱灯や蛍光灯では、電気代がかさみ省エネが求められていた。
省エネのためのＬＥＤを光源として用いた提案があるが、なをいっそうの省エネが求められている。The use of incandescent bulbs has a problem such as the heat inside and becomes hot, and incandescent and fluorescent lamps are costly and require energy savings.
There is a proposal that uses an LED for energy saving as a light source, but more energy saving is required.

本考案の間接照明器具（１）は模様を有するシート（２）の内側に光拡散シート（３）を重ねあわせて複合シート（４）としこの複合シート（４）を照明器具の照明面とし光源としてチップＬＥＤ（５）を用いたことを特徴とする．The indirect lighting device (1) of the present invention has a light diffusion sheet (3) superimposed on the inner side of a patterned sheet (2) to form a composite sheet (4), and this composite sheet (4) is used as an illumination surface of the lighting device. As a feature, a chip LED (5) is used.

本考案で用いる模様を有するシート（２）としては例えば和紙に絵を描いたもの、和紙に形状のある例えばモミジなとを抄きこんだもの、繊機で用いる紋紙などが挙られる．
本考案で用いる光拡散シート（３）としては片面が粒面にされている、半透明シートをいい、液晶表示板に用いられているシートがより好適である。
本考案では上記模様を有するシート（２）と上記光拡散シート（３）とを重ねあわせて複合シート（４）とする。
複合シート（４）の作り方としては全面接着剤等ではり合せても良いが、周囲のみを接着する方が好ましい。
この複合シート（４）は照明器具の照明面として用いる。
角筒形の場合は周囲四面と天井面の五面、丸筒形の場合は周囲全面と天井面をこの複合シートで作る。
光源としてはチップＬＥＤを用いる。
六連型や十二連型のチップＬＥＤが好ましい。
光電源を置く位置としては、照明器具の下方又は底部が好ましい．
底部に置いても、光拡散シートの効果により照明面の下方も上方も天井面も同じ様な照度が得られるものです。Examples of the sheet (2) having a pattern used in the present invention include a drawing on Japanese paper, a Japanese paper with a shape such as a maple, and a paper used on a textile machine.
The light diffusing sheet (3) used in the present invention is a translucent sheet having a grain surface on one side, and a sheet used for a liquid crystal display panel is more preferable.
In the present invention, the sheet (2) having the above pattern and the light diffusion sheet (3) are overlapped to form a composite sheet (4).
As a method of making the composite sheet (4), it may be bonded with a whole surface adhesive or the like, but it is preferable to bond only the periphery.
This composite sheet (4) is used as an illumination surface of a luminaire.
In the case of a rectangular tube shape, the surrounding four surfaces and the ceiling surface are made of this composite sheet, and in the case of a round tube shape, the entire surrounding surface and the ceiling surface are made of this composite sheet.
A chip LED is used as the light source.
A 6-type or 12-type chip LED is preferred.
The position where the light source is placed is preferably below or at the bottom of the lighting fixture.
Even when placed on the bottom, the light diffusing sheet has the same illuminance below and above the lighting surface as well as the ceiling surface.

光拡散シートを使用して光源をチップＬＥＤを用いるのですべての照明面の個所から均一な照明を得られまた模様が浮び上がり幻妙な効果を生じる、またチップＬＥＤを用いているので電力消費が非常に少ない上構造上作り易くコストも安く出来る
長時間使用しても、白熱灯のような熱くなったり内部に熱が、こもったりしない．Since chip LEDs are used as the light source by using a light diffusion sheet, uniform illumination can be obtained from all the lighting surfaces, and the pattern rises to produce a phantom effect. Also, since chip LEDs are used, power consumption is reduced. Even if it is used for a long time because it is very small and easy to make, and the cost is low, it does not get hot like an incandescent lamp or heat builds up inside.

以下本考案の実施の一例と図面を用いて説明する。
模様を有するシートとして西陣織の繊機で用いる、紋紙を使用した（図１）。
厚さ３ｍ／ｍ
この紋紙の片面に光拡散シートとして株式会社ツジテン社製「ＰＣＭ３」光拡散シートを粗面側を表側にして周囲を接着剤で施こして重せあわせ複合シート（４）とした（図３）。
この複合シートたて３３ｃｍよこ１３ｃｍのものを４枚１３ｃｍ×１３ｃｍを１枚用意し木製の溝付き桟（６）を用いてつくった高さ３８ｃｍよこ１６ｃｍ、の照明器具の枠体にこの複合シート（４）を側面に４枚と天井１枚を桟の溝を利用してはめこんだ。
底面はアルミ板で作った。この底面、内部上部に６連チップＬＥＤ（５）を２本並べて水平におき、ここからリード線にてコンセントにつないだ（図５）。
こうして得た間接照明器具（１）は照明を入れたときの紋紙の模様が浮き出て、おちついた雰囲気を、又紋様によっては、日本調に洋風にも合うのでは、ないかと思われる。
図５の（ロ）は本考案によって丸筒型の照明器具を得た図を示す。Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
A pattern paper used in a Nishijin textile machine was used as a sheet having a pattern (FIG. 1).
Thickness 3m / m
As a light diffusing sheet, a “PCM3” light diffusing sheet manufactured by Tsuji Ten Co., Ltd. was applied on one side of the paper as a light diffusing sheet, with the rough side facing the front side, and the periphery was coated with an adhesive to obtain a composite sheet (4) (FIG. ).
This composite sheet is 33cm wide and 13cm wide, prepared as a frame of a lighting fixture with a height of 38cm and a width of 16cm, prepared using four 13cm x 13cm sheets of wooden grooved bars (6). (4) was fitted on the side with 4 pieces on the side and 1 piece on the ceiling using the groove of the crosspiece.
The bottom was made of an aluminum plate. Two 6-chip LEDs (5) were placed side by side on the bottom and inside the top and placed horizontally, and connected to an outlet with lead wires (Fig. 5).
The indirect lighting device (1) obtained in this way appears to have a patterned paper pattern when the light is turned on, and it seems that it may fit in a Japanese-style Western style depending on the pattern.
(B) of FIG. 5 shows the figure which obtained the round-tube type lighting fixture by this invention.

Industrial applicability
