［作 用］
本発明は以上の構成からなり、次にその作用を説明する
。[Function] The present invention has the above configuration, and its function will be explained next.
本発明の装置では、そのレッド蛍光集光体と、グリーン
蛍光集光体と、ブルー蛍光集光体とを積層して波長変換
集光部を形成している。In the device of the present invention, the red fluorescent light collector, green fluorescent light collector, and blue fluorescent light collector are laminated to form a wavelength conversion light collector.
これにおいて、この波長変換集光部は各集光体を、レッ
ド蛍光集光体、グリーン蛍光集光体、ブルー蛍光集光体
の順で積層配置し、レッド蛍光集光体側から外光、例え
ば太陽光を入射する構成とすることが好ましい。In this case, the wavelength conversion light condensing unit arranges each light condenser in a stacked manner in the order of red fluorescence condenser, green fluorescence condenser, and blue fluorescence condenser, and receives external light from the red fluorescence concentrator side, e.g. It is preferable to adopt a configuration in which sunlight is incident.

、グリーン光（波長５００〜６００ ｎｍ）の大部分が
レッド蛍光集光体に吸収され、レッド光（波長６００〜
７００ ｎｍ）が蛍光として放出される。As a result, when sunlight enters the wavelength conversion concentrator, most of the green light (wavelength 500 to 600 nm) from the ultraviolet to visible light range (wavelength 340 to 700nII) is absorbed by the red fluorescent condenser. and red light (wavelength 600 ~
700 nm) is emitted as fluorescence.

して、このグリーン蛍光集光体からは、グリーン光（波

0-500 rrn) is absorbed here. Green light (wavelength 500 to 600 nm) is emitted as fluorescence from this green fluorescence condenser.
さらに、前記各蛍光集光体で吸収されなかった太陽光は
、さらにブルー蛍光集光体に入射され、ここで紫外線（
波長３４０〜４００ ｎａ＋）の大部分が吸収される。Furthermore, the sunlight that is not absorbed by each of the fluorescent concentrators is further incident on the blue fluorescent concentrator, where the ultraviolet light (
Most of the wavelengths (340-400 na+) are absorbed.
そして、このブルー蛍光集光体からは、プル−光（波長
４００〜５００ ｎｍ）が蛍光として放出される。Then, pull light (wavelength 400 to 500 nm) is emitted as fluorescence from this blue fluorescence condenser.

太陽光をより高い効率で利用することができる。In addition, in the present invention, in order to reuse the light that is not absorbed by each of the fluorescent condensers, it is preferable to provide a reflecting plate as described in claim (3). As a result, the sunlight that is not absorbed by each fluorescent concentrator is reflected by the reflector, and when it passes through each fluorescent concentrator again, it is absorbed and becomes fluorescent.
Sunlight can be used more efficiently.
そして、各蛍光集光体から放出されたレッド。and red emitted from each fluorescent concentrator.

返し伝送導波路に良好に導かれる。Most of the green and blue fluorescence undergoes total internal reflection repeatedly inside the condenser and reaches the light collection waveguide provided in each condenser. Each fluorescence is guided to a transmission waveguide via each of these light collection waveguides. In this case, each condensing waveguide is preferably formed into a tapered shape in order to improve coupling with the transmission waveguide, and in order to further reduce the waveguide loss, the surface is coated with a reflective film or the refractive It is preferable to make the index distribution non-uniform so that the refractive index increases toward the center. As a result, the fluorescent light is repeatedly totally reflected inside each light collection waveguide and guided to the transmission waveguide in a good manner.
伝送導波路では、導かれた各レッド、グリーンおよびブ

光の加法混色の原理により白色光が放出されることにな
る。In the transmission waveguide, the guided red, green, and blue fluorescence is mixed. Therefore, white light is emitted from the output end according to the principle of additive color mixing of colored lights.
このように、本発明によれば、太陽光の可視から紫外域

を得ることができる。As described above, according to the present invention, it is possible to effectively utilize sunlight in the visible to ultraviolet range to obtain white light that is effective as indoor illumination light.

徴がある。In particular, sunlight has ultraviolet rays (wavelengths from 340 to 340) that are unnecessary for lighting.
400nIIl) and infrared rays (wavelength 700-2000nm)
), but the white light obtained using the device of the present invention has these ultraviolet and infrared rays harmful to the human body removed through wavelength conversion, so compared to lighting that uses sunlight directly, It has the characteristic that there is no risk of harm to the eyes or skin.
さらに、赤外線は熱線ともいわれ、室内温度を上昇させ
夏期には冷房付加の増大をもたらすが、本発明の装置を

る。Furthermore, infrared rays are also called heat rays and cause an increase in indoor temperature and increase the need for air conditioning in the summer. However, by using the device of the present invention, it is possible to obtain white light that cuts out this infrared rays, thereby reducing the cooling load. The increase can be prevented.
なお、本発明の波長変換集光部のように、複数の蛍光集
光体を積層配置したものにあっては、各蛍光集光体の上
面と下面からは全反射角の条件を満さない蛍光が流出す
るが、それらの大部分は蛍光集光体で再び集光される。In addition, in the case of a structure in which a plurality of fluorescent light concentrators are arranged in a stacked manner, such as the wavelength conversion light collecting section of the present invention, the total reflection angle condition is not satisfied from the top and bottom surfaces of each fluorescent light collector. Fluorescent light flows out, but most of it is re-collected by the fluorescent concentrator.
すなわち、各蛍光集光体を請求項（２）のように積層配
置したものにあっては、ブルー蛍光集光体の上面から流
出する蛍光は、その真上のグリーン蛍光集光体の吸収ス
ペクトルと一致するため、このグリーン蛍光集光体で吸
収されグリーン光に変換される。ブルー蛍光集光体の下
面から流出する蛍光は、請求項（３）のように反射板を
設けている場合にはそのすぐ真下の反射板で反射され、
ブルー蛍光集光体を透過しグリーン蛍光集光体に入射し
て吸収され、グリーン光に変換される。In other words, in the case where the fluorescent condensers are arranged in a stacked manner as in claim (2), the fluorescence flowing out from the top surface of the blue fluorescent condenser has an absorption spectrum of the green fluorescent condenser directly above it. This green fluorescent light is absorbed by the concentrator and converted into green light. When a reflecting plate is provided as in claim (3), the fluorescent light flowing out from the lower surface of the blue fluorescent condenser is reflected by the reflecting plate immediately below the reflecting plate,
The light passes through the blue fluorescent light collector, enters the green fluorescent light collector, is absorbed, and is converted into green light.
グリーン蛍光集光体の上面から流出する蛍光は、そのす
ぐ真上のレッド蛍光集光体の吸収スペクトルと一致して
いるため、このレッド蛍光集光体で吸収されレッド光に
変換される。グリーン蛍光集光体の下面から流出する蛍
光は、ブルー蛍光集光体内を透過し、反射板で反射され
、再びブルー蛍光集光体、グリーン蛍光集光体内を透過

に変換される。なお、レッド蛍光集光体の上面、下面か
ら流出する蛍光は、グリーン蛍光集光体、ブルー蛍光集
光体の吸収スペクトルと一致しないため、これだけは損
失となる。The fluorescence flowing out from the top surface of the green fluorescent condenser matches the absorption spectrum of the red fluorescent condenser directly above it, and is therefore absorbed by this red fluorescent condenser and converted into red light. Fluorescence flowing out from the bottom surface of the green fluorescent condenser passes through the blue fluorescent condenser, is reflected by the reflector, passes through the blue fluorescent concentrator, green fluorescent concentrator again, and enters the red fluorescent condenser. It enters, is absorbed, and converted into red light. Note that the fluorescence flowing out from the upper and lower surfaces of the red fluorescent condenser does not match the absorption spectra of the green fluorescent condenser and the blue fluorescent condenser, so this is a loss.
このように、本発明によれば、各蛍光集光体から流出し
た蛍光は、他の蛍光集光体において吸収されるため、太
陽光の吸収効率は極めて高く、各蛍光集光体をそれぞれ
単独で用いた場合に比べ、太陽光から白色光や、その他
各色の光を効率良く得ることが可能となる。As described above, according to the present invention, the fluorescence flowing out from each fluorescent concentrator is absorbed by the other fluorescent concentrators, so the sunlight absorption efficiency is extremely high, and each fluorescent concentrator can be used independently. This makes it possible to more efficiently obtain white light and other colors of light from sunlight than when used in
また、本発明は請求項（４）に記載のように、レッド、
グリーンおよびブルーの各蛍光の光路にそれぞれ光シャ
ッターを設け、各光シャッターを開閉制御することによ
り、伝送導波路の出力端から異なる色の光を得ることが
でき、例えばショーウィンドー等の照明用としてその幅
広い用途が期待される。Further, the present invention provides, as described in claim (4), red,
By installing optical shutters in the optical paths of each green and blue fluorescent light and controlling the opening and closing of each optical shutter, it is possible to obtain light of different colors from the output end of the transmission waveguide. For example, it is possible to obtain light of different colors from the output end of the transmission waveguide. It is expected that it will find a wide range of uses.
