Description

この発明は、空隙を有する基体に蛍光体を担持させて成る蛍光体担持体に係り、特に、基体に担持させる蛍光体の量及び表面積を増大させることができる蛍光体担持体に関する。   The present invention relates to a phosphor support in which a phosphor is supported on a substrate having voids, and more particularly to a phosphor support that can increase the amount and surface area of the phosphor supported on the substrate.

図６は、従来の蛍光体担持体70の一例を示すものであり、該蛍光体担持体70は、多数の繊維72を略格子状に織り込んで形成したシート状の織布を基体74と成し、該基体74（織布）を構成する繊維72の表面に蛍光体76を担持させて成る。上記基体74（織布）は、繊維72間に多数の空隙78が形成されている。
上記基体74（織布）への蛍光体76の担持は、例えば、粒子状の蛍光体76が分散された樹脂液中に、基体74（織布）を浸漬した後乾燥させることにより行われる。 FIG. 6 shows an example of a conventional phosphor carrier 70. The phosphor carrier 70 comprises a base 74 and a sheet-like woven fabric formed by weaving a large number of fibers 72 in a substantially lattice shape. The phosphors 76 are supported on the surfaces of the fibers 72 constituting the substrate 74 (woven fabric). The base body 74 (woven fabric) has a large number of voids 78 formed between the fibers 72.
The phosphor 76 is supported on the substrate 74 (woven fabric) by, for example, immersing the substrate 74 (woven fabric) in a resin liquid in which the particulate phosphor 76 is dispersed and then drying.

ところで、上記蛍光体76から放射される光の輝度は、蛍光体76の量及び表面積に略比例することから、蛍光体担持体70の輝度を向上させるためには、基体74に担持させる蛍光体76の量及び表面積をできるだけ増大するのが望ましい。
しかしながら、上記従来の蛍光体担持体74にあっては、基体74（織布）の空隙78
部分には蛍光体76が配置されていないことから、基体74（織布）に担持できる蛍光体72の量には限界があった。 By the way, since the luminance of the light emitted from the phosphor 76 is substantially proportional to the amount and surface area of the phosphor 76, in order to improve the luminance of the phosphor carrier 70, the phosphor carried on the substrate 74 is used. It is desirable to increase the amount and surface area of 76 as much as possible.
However, in the above-described conventional phosphor support 74, the gap 78 of the base body 74 (woven fabric) is used.
Since the fluorescent substance 76 is not disposed in the portion, there is a limit to the amount of the fluorescent substance 72 that can be supported on the base body 74 (woven cloth).

本発明は、上記従来の問題点に鑑みてなされたものであり、その目的とするところは、空隙を有する基体に担持させる蛍光体の量及び表面積を増大させることができる蛍光体担持体の実現にある。   The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to realize a phosphor-supporting body capable of increasing the amount and surface area of the phosphor to be supported on a substrate having voids. It is in.

上記の目的を達成するため、本発明に係る蛍光体担持体は、空隙を有する基体の表面に蛍光体を担持させると共に、上記空隙に蛍光体を膜状に配置させることを特徴とする。
上記基体は、繊維を織り込み、繊維間に多数の空隙が形成されている織布で構成することができる。 In order to achieve the above object, the phosphor carrier according to the present invention is characterized in that the phosphor is supported on the surface of a substrate having voids, and the phosphor is arranged in a film shape in the voids.
The substrate can be composed of a woven fabric in which fibers are woven and a large number of voids are formed between the fibers.

本発明の蛍光体担持体にあっては、基体の表面のみならず、基体の空隙にも蛍光体が担持されていることから、基体に担持する蛍光体の量及び表面積を増大させることができる。   In the phosphor carrier of the present invention, since the phosphor is supported not only on the surface of the substrate but also in the voids of the substrate, the amount and surface area of the phosphor supported on the substrate can be increased. .

以下、図面に基づき、本発明に係る蛍光体担持体の実施形態を説明する。
図１は、本発明に係る第１の蛍光体担持体10を示すものであり、該第１の蛍光体担持体10は、図２に示すように、多数の繊維12を略格子状に織り込んで形成したシート状の織布を基体14としており、該基体14（織布）は、繊維12間に多数の空隙16が形成されている。
上記繊維12は、ナイロン、ポリエステル、アクリル、ポリプロピレン、フッ素樹脂等の樹脂繊維、レーヨン等のセルロース系の化学繊維、ガラス繊維、アルミナ、ボロン等の金属繊維、天然繊維等を用いることができる。 Hereinafter, embodiments of the phosphor carrier according to the present invention will be described with reference to the drawings.
FIG. 1 shows a first phosphor carrier 10 according to the present invention. As shown in FIG. 2, the first phosphor carrier 10 weaves a large number of fibers 12 in a substantially lattice shape. The sheet-like woven fabric formed in step 1 is used as the base 14, and the base 14 (woven fabric) has a large number of voids 16 formed between the fibers 12.
As the fibers 12, resin fibers such as nylon, polyester, acrylic, polypropylene and fluororesin, cellulosic chemical fibers such as rayon, glass fibers, metal fibers such as alumina and boron, natural fibers, and the like can be used.

また、上記基体14（織布）を構成する繊維12の表面には蛍光体18が被着・担持されていると共に、繊維12間の空隙16にも蛍光体18が膜状に配置されている。
上記基体14（織布）への蛍光体18の担持は、粒子状の蛍光体18が多数分散された樹脂液（蛍光体分散液）中に、基体14（織布）を浸漬した後乾燥させることにより行うことができる。
この際、蛍光体分散液の組成、粘度、表面張力、乾燥条件等を適宜選定することにより、繊維12間の空隙16に蛍光体18を膜状に配置することが可能である。
尚、蛍光体18の膜厚が大きいと、光の透過率が悪くなると共に、光の自己吸収（蛍光体18で波長変換された光の一部が蛍光体18自身によって吸収されること）も大きくなり、その結果、光の取り出し効率が不良となるため、繊維12の表面に被着される蛍光体18の膜厚は１０〜５０μｍが好ましい。
また、繊維12間の空隙16に配置される蛍光体18の膜厚は５〜３０μｍが好ましい。これにより、蛍光体18で波長変換される光量を十分に得ることができると共に、光の透過率も良好であり、光の取り出し効率が高い。
尚、上記空隙16の開口率（各空隙16を囲繞する繊維12を含む領域の面積に対する各空隙16の開口面積の割合。図３においては、ａ×ｂ／Ａ×Ｂ×１００％）が大きい程、空隙16部分に担持される蛍光体の量及び表面積を増大させることができ、例えば、空隙16の開口率を５０〜９５％とした場合には、蛍光体の量及び表面積を大きく確保することができる。 Further, a phosphor 18 is deposited and supported on the surface of the fiber 12 constituting the substrate 14 (woven fabric), and the phosphor 18 is also arranged in a film shape in the gap 16 between the fibers 12. .
The phosphor 14 is supported on the substrate 14 (woven fabric) by immersing the substrate 14 (woven fabric) in a resin liquid (phosphor dispersion) in which a large number of particulate phosphors 18 are dispersed and then drying. Can be done.
At this time, the phosphor 18 can be arranged in a film shape in the gaps 16 between the fibers 12 by appropriately selecting the composition, viscosity, surface tension, drying conditions and the like of the phosphor dispersion.
In addition, when the film thickness of the phosphor 18 is large, the light transmittance is deteriorated and light self-absorption (a part of the light wavelength-converted by the phosphor 18 is absorbed by the phosphor 18 itself) is also included. As a result, the light extraction efficiency becomes poor. As a result, the film thickness of the phosphor 18 deposited on the surface of the fiber 12 is preferably 10 to 50 μm.
The film thickness of the phosphor 18 disposed in the gap 16 between the fibers 12 is preferably 5 to 30 μm. As a result, a sufficient amount of light whose wavelength is converted by the phosphor 18 can be obtained, the light transmittance is good, and the light extraction efficiency is high.
Note that the opening ratio of the voids 16 (the ratio of the opening area of each void 16 to the area of the region including the fibers 12 surrounding each void 16; a × b / A × B × 100% in FIG. 3) is large. As a result, the amount and surface area of the phosphor supported in the void 16 portion can be increased. For example, when the aperture ratio of the void 16 is set to 50 to 95%, a large amount and surface area of the phosphor are ensured. be able to.
