図１は、本発明にかかる光源装置に用いられるリング形状の放電管を有する無電極放電灯にＬＥＤを組み込んだ光源装置の一例を示した概念図である。本発明において、リング形状の放電管を有する無電極放電灯の放電管１は外部に電界印加用コイル３を備えており、これから生ずる電界により放電管内にプラズマを励起する。無電極放電灯の上部には反射板４を配置したが、反射板は必ずしも必要なく、セードタイプ等他の形状のものを用いても問題ない。なお、無電極放電灯がより有利であり、本実施例に於いても無電極放電灯を用いたが、一般の放電灯を用いても問題ない。 FIG. 1 is a conceptual diagram showing an example of a light source device in which an LED is incorporated in an electrodeless discharge lamp having a ring-shaped discharge tube used in the light source device according to the present invention. In the present invention, a discharge tube 1 of an electrodeless discharge lamp having a ring-shaped discharge tube is provided with an electric field applying coil 3 outside, and plasma is excited in the discharge tube by an electric field generated therefrom. Although the reflecting plate 4 is arranged on the upper part of the electrodeless discharge lamp, the reflecting plate is not always necessary, and there is no problem even if other shapes such as a shade type are used. An electrodeless discharge lamp is more advantageous, and an electrodeless discharge lamp is used in this embodiment, but there is no problem even if a general discharge lamp is used.
本実施例に於いては、リング形状の放電管を有する無電極放電灯の放電管１のリング内にＬＥＤ素子２を配設した。かかる位置にＬＥＤ発光デバイスを配設したことにより、前記複数の発光素子の夫々の弱点を補完し、広域照射や広域波長の照射と光の強弱、点滅、スポットライト的な使用を含む制御に対応するとともに、必要な波長域の光量を得ることの出来る、特に植物工場への応用に適した光源装置であった。なお、ＬＥＤ発光デバイスを配設する位置はリング形状の放電管の外周など他の位置であっても問題ない。 In this embodiment, the LED element 2 is disposed in the ring of the discharge tube 1 of the electrodeless discharge lamp having a ring-shaped discharge tube. By arranging the LED light emitting device at such a position, it complements each weak point of the plurality of light emitting elements, and supports control including wide area irradiation, wide wavelength irradiation and light intensity, blinking, spotlight use In addition, the light source device can obtain a light amount in a necessary wavelength range, and is particularly suitable for application to a plant factory. There is no problem even if the LED light emitting device is disposed at other positions such as the outer periphery of the ring-shaped discharge tube.
かかる光源装置は、特に植物工場への応用に適する。図３は、本発明にかかる光源装置を用いた植物の育成方法の利点を示す比較図である。ここに示すように、図３中の上に示されるようにＬＥＤのみを光源装置とした場合には、ＬＥＤの配光の指向性により植物工場の対象植物全体に均一な光量での光照射をすることは困難であったが、無電極放電灯を併用することによって配光特性が向上し、広域照射や広域波長の照射と光の強弱、点滅、スポットライト的な使用を含む制御に対応するとともに、必要な波長域の光量を得ることの出来る、特に植物工場への応用に適した光源装置及び光源装置を用いた植物の育成方法が実現された。 Such a light source device is particularly suitable for application to a plant factory. FIG. 3 is a comparative view showing advantages of a plant growing method using the light source device according to the present invention. As shown here, when only the LED is used as the light source device as shown in the upper part of FIG. 3, light irradiation with a uniform light amount is applied to the entire target plant of the plant factory by the directivity of the light distribution of the LED. Although it was difficult to do so, the light distribution characteristics are improved by using an electrodeless discharge lamp together, and it corresponds to control including wide area irradiation, irradiation of wide wavelength and intensity of light, blinking, spotlight use At the same time, a light source device capable of obtaining a light quantity in a necessary wavelength range and particularly suitable for application to a plant factory and a plant growing method using the light source device have been realized.
図４は、ＬＥＤの一般的な波長特性を説明するための、赤色ＬＥＤの波長特性の一例を示した概念図である。本発明は、複数の発光デバイスに含まれるＬＥＤ発光デバイスとして異なった波長にピークを有する複数のＬＥＤ素子を用いたことを特徴とする。さらに本発明は複数の発光デバイスに含まれるＬＥＤ発光デバイスは異なった波長にピークを有する複数のＬＥＤ素子を用い、ピーク波長が少なくとも赤色域及び／又は青色域にあるＬＥＤ発光デバイスを含むことを特徴とする。 FIG. 4 is a conceptual diagram illustrating an example of a wavelength characteristic of a red LED for explaining a general wavelength characteristic of the LED. The present invention is characterized in that a plurality of LED elements having peaks at different wavelengths are used as LED light-emitting devices included in the plurality of light-emitting devices. Furthermore, the present invention is characterized in that the LED light-emitting device included in the plurality of light-emitting devices includes a plurality of LED elements having peaks at different wavelengths, and includes an LED light-emitting device having a peak wavelength in at least a red region and / or a blue region. And
ＬＥＤは、図４に典型例が示されるようにピーキーな波長特性を有する。ここで、植物は葉緑素に於いて光エネルギーを吸収して光合成を行うのであるが、その吸収特性は可視光の緑に於いて低く赤或いは青の波長域に於いて相対的に高い。しかし、その特性は対象植物の種類によって一定でない。また、同一の植物であってもその成長過程において最適な波長特性は変化する。 The LED has a peaky wavelength characteristic as shown in a typical example in FIG. Here, the plant absorbs light energy in chlorophyll and performs photosynthesis, but its absorption characteristic is low in the visible light green and relatively high in the red or blue wavelength region. However, the characteristics are not constant depending on the type of target plant. Even in the same plant, the optimum wavelength characteristic changes during the growth process.
図５は、葉緑素の吸収スペクトルと一種のＬＥＤの発光スペクトルの例を示した概念図である。（LEDs Magazine Japan誌２０１１年９月号１５ページ、モーリー・ライト「LED 光源で植物の成長を促進、赤色光／青色光の波長が鍵に」より引用）このように、光合成に有効な波長には分布があり、これに対応した光源を用いることが植物育成に有効である。 FIG. 5 is a conceptual diagram showing an example of an absorption spectrum of chlorophyll and an emission spectrum of a kind of LED. (Source: LEDS Magazine Japan, September 2011, page 15; Molly Wright, "Accelerating plant growth with LED light sources, red and blue light wavelengths as key") Has a distribution, and it is effective for plant growth to use a light source corresponding to the distribution.
図６は、青色ＬＥＤ、白色ＬＥＤ及び無電極放電灯の発光スペクトルデータのグラフである。ＬＥＤとしては典型的な市販のものを用いてデータを取得し、無電極放電灯としては天草池田電機株式会社製のものを用いてスペクトルデータを取得した。このデータからわかるように青色ＬＥＤ及び白色ＬＥＤはいずれも発光波長範囲が狭く、図５の示された葉緑素の吸収スペクトルの大部分をカバーすることは出来ない。しかし、無電極放電灯は広範囲に発光が得られることから、ＬＥＤと組み合わせることにより葉緑素の吸収スペクトルの大部分をカバーすることが出来るようになることがわかる。 FIG. 6 is a graph of emission spectrum data of a blue LED, a white LED, and an electrodeless discharge lamp. Data was obtained using a typical commercially available LED, and spectrum data was obtained using an electrodeless discharge lamp manufactured by Amakusa Ikeda Electric Co., Ltd. As can be seen from this data, both the blue LED and the white LED have a narrow emission wavelength range and cannot cover most of the absorption spectrum of the chlorophyll shown in FIG. However, since the electrodeless discharge lamp emits light in a wide range, it can be understood that most of the absorption spectrum of chlorophyll can be covered by combining with the LED.
葉緑素の光エネルギー吸収特性に最適化するとともに、対象植物の種類や成長過程において変化する最適な波長特性を実現するために、本発明に係る光源装置は有効であった。即ち、複数の発光デバイスに含まれるＬＥＤ発光デバイスは異なった波長にピークを有する複数のＬＥＤ素子を用い、ピーク波長が少なくとも赤色域及び／又は青色域にあるＬＥＤ発光デバイスを含むことにより、夫々のＬＥＤ発光デバイス及び無電極放電灯を個々に制御することにより、広域照射や広域波長の照射と光の強弱、点滅、スポットライト的な使用を含む制御に対応するとともに、必要な波長域の光量を得ることの出来る、特に植物工場への応用に適した光源装置及び光源装置を用いた植物の育成方法が実現された。 The light source device according to the present invention is effective for optimizing the light energy absorption characteristics of chlorophyll and for realizing the optimum wavelength characteristics that change in the type and growth process of the target plant. That is, each of the LED light emitting devices included in the plurality of light emitting devices includes a plurality of LED elements having peaks at different wavelengths, and includes LED light emitting devices having peak wavelengths in at least the red region and / or the blue region. By individually controlling LED light-emitting devices and electrodeless discharge lamps, it supports control including wide-area irradiation, wide-wavelength irradiation, intensity of light, blinking, and spotlight-like use, and the amount of light in the required wavelength range. A light source device that can be obtained, particularly suitable for application to a plant factory, and a plant growing method using the light source device have been realized.
図７は、4種類の光源条件の育成箱を用いたルッコラの成長観察実験の結果を示すグラフである。植物育成におけるＬＥＤ発光デバイスと無電極放電灯の複合化による育成向上を検討するため、実験を行った。縦横６０cmの領域に、高さ１２０cmから前記照明を行い、これをモデルの植物工場として、ルッコラを２０株水耕育成させた。 FIG. 7 is a graph showing the results of an arugula growth observation experiment using growth boxes with four types of light source conditions. An experiment was conducted to examine the improvement of growth by combining LED light-emitting devices and electrodeless discharge lamps in plant growth. The above-mentioned illumination was performed from a height of 120 cm in a region of 60 cm in length and width, and this was used as a model plant factory to grow 20 arugula hydroponics.
ＬＥＤ発光デバイスを無電極放電灯の光強度が低い部分に配置して実験を行った。ルッコラは２０株使用し、Ｂ群の最長の葉の長さの平均１８cmになった時点で観察を行った実験１は無電極放電灯のみ、実験２は無電極放電灯に加えてＣ群にＬＥＤ発光デバイスを配置、実験３は無電極放電灯に加えてＡ群にＬＥＤ発光デバイスを配置、実験４は無電極放電灯に加えてＡ群とＣ群にＬＥＤ発光デバイスを配置した。 An experiment was conducted by placing the LED light emitting device in a portion where the light intensity of the electrodeless discharge lamp was low. 20 arugulas were used, and when the average length of the longest leaves of group B reached 18 cm, experiment 1 was conducted only for the electrodeless discharge lamp, and experiment 2 was applied to the group C in addition to the electrodeless discharge lamp. In the experiment 3, an LED light emitting device was arranged in the A group in addition to the electrodeless discharge lamp. In an experiment 4, an LED light emitting device was arranged in the A group and the C group in addition to the electrodeless discharge lamp.
結果として、明らかに、ＬＥＤ発光デバイスを配置して照明ムラを低減させることで、育成状況が向上した。すなわち、面光源である無電極放電灯を用いることで、ある程度の面積で光を照射し、照射ムラや葉の影などを点光源であるＬＥＤ発光デバイスでカバーすることに成功し、植物工場において有効であることが証明された。 As a result, obviously, the rearing situation was improved by arranging the LED light emitting device to reduce the illumination unevenness. In other words, by using an electrodeless discharge lamp that is a surface light source, it was possible to irradiate light in a certain area and to cover irradiation unevenness and leaf shadows with LED light emitting devices that are point light sources. Proven to be effective.
図２は、本発明にかかる光源装置に用いられる電球形状の放電管を有する無電極放電灯にＬＥＤを組み込んだ光源装置の一例を示した概念図である。本実施例に用いた電球形状の放電管を有する無電極放電灯に於いても、実施例１と同様の効果が得られ、広域照射や広域波長の照射と光の強弱、点滅、スポットライト的な使用を含む制御に対応するとともに、必要な波長域の光量を得ることの出来る、特に植物工場への応用に適した光源装置及び光源装置を用いた植物の育成方法が実現された。なお、無電極放電灯がより有利であり、本実施例に於いても無電極放電灯を用いたが、一般の放電灯を用いても問題ない。 FIG. 2 is a conceptual diagram showing an example of a light source device in which an LED is incorporated in an electrodeless discharge lamp having a bulb-shaped discharge tube used in the light source device according to the present invention. In the electrodeless discharge lamp having the bulb-shaped discharge tube used in this example, the same effect as in Example 1 can be obtained, and wide-area irradiation, wide-range wavelength irradiation and light intensity, blinking, and spotlight-like A light source device and a method for growing a plant using the light source device, which are particularly suitable for application to a plant factory, have been realized that can cope with control including various uses and can obtain a light quantity in a necessary wavelength range. An electrodeless discharge lamp is more advantageous, and an electrodeless discharge lamp is used in this embodiment, but there is no problem even if a general discharge lamp is used.
本実施例に於いては、本発明に係る光源装置を植物の育成方法ではなく液晶表示素子のバックライトに用いた。構成としては、バックライト用の拡散反射板の一方の端面にＬＥＤを、他方の端面に細管の無電極放電灯を配設した。 In this example, the light source device according to the present invention was used for the backlight of the liquid crystal display element rather than the plant growing method. As a configuration, an LED is disposed on one end face of a diffuse reflection plate for a backlight, and a thin tube electrodeless discharge lamp is disposed on the other end face.
かかる構成とすることにより、無電極放電ランプによりＬＥＤの波長分布の偏りを補完することが可能となり、液晶表示素子の演色性能を向上させることができる。 By adopting such a configuration, it becomes possible to supplement the bias of the wavelength distribution of the LED by the electrodeless discharge lamp, and the color rendering performance of the liquid crystal display element can be improved.
図８は、本発明にかかる光源装置に用いられる電球形状の放電管を有する無電極放電灯にＬＥＤを組み込んだ光源装置の他の例を示した概念図である。なお、図８に於いて破線で記載された部分は放電管の内部に配置された部分を示している。本実施例では、無電極放電灯として励起用電極を放電管内部に配設した放電管を用い、該放電管の放電管内部にさらにＬＥＤ発光デバイスを配設した。かかる構成により、無電極放電灯とＬＥＤ発光デバイスの相乗効果をさらに高めることができ、また、配線や制御の面でも有利な構成とすることができた。 FIG. 8 is a conceptual diagram showing another example of a light source device in which an LED is incorporated in an electrodeless discharge lamp having a bulb-shaped discharge tube used in the light source device according to the present invention. In FIG. 8, a portion indicated by a broken line indicates a portion disposed inside the discharge tube. In this example, a discharge tube having an excitation electrode disposed inside a discharge tube as an electrodeless discharge lamp was used, and an LED light emitting device was further disposed inside the discharge tube of the discharge tube. With this configuration, the synergistic effect of the electrodeless discharge lamp and the LED light emitting device can be further enhanced, and the configuration can be made advantageous in terms of wiring and control.
本実施例においては、本発明にかかる光源装置を昼間と夜間において使用目的の異なる用途に用いた。具体的には、本実施例においてはガソリンスタンドにおける照明として用いた。ガソリンスタンドは、夜間は全体を照明する必要があるが、昼間はその開店を運転者に知らせるため特定の色の灯火を点灯しておくことが必要となっている。ここで、夜間用の照明を常時点灯することは非常に無駄であり、またかかる照明は一般に昼光色であって前記の運転者へのアピールには適さない。 In this example, the light source device according to the present invention was used for different purposes for use during the day and at night. Specifically, in this example, it was used as illumination at a gas station. The gas station needs to be illuminated at night, but in the daytime it is necessary to light a specific color to inform the driver of the opening. Here, it is very wasteful to always turn on the illumination for nighttime, and such illumination is generally daylight color and is not suitable for appealing to the driver.
そこで、ピーク波長が黄色、赤、オレンジ或いは紫色の領域にあるＬＥＤ発光デバイスを含むＬＥＤ発光デバイスと無電極放電灯を組み合わせた照明装置を用い、昼間はＬＥＤ発光デバイスのみを発光させ、夜間は無電極放電灯のみ或いは無電極放電灯及びＬＥＤ発光デバイスの併用により、経済的にも優れ、使用目的に合致した照明装置を提供することができた。 Therefore, an illuminator that combines an LED light-emitting device including an LED light-emitting device with a peak wavelength in the yellow, red, orange, or purple region and an electrodeless discharge lamp is used. By using only the electrode discharge lamp or the electrodeless discharge lamp and the LED light emitting device in combination, it is possible to provide an illumination device that is economically excellent and meets the purpose of use.
また、本実施例にかかる形態は、用途が体育館、図書館、学習室、事務所、卓上或いは商品展示場所における照明等、全体照明とスポット照明の双方が必要とされる用途において有効である。さらに、工事現場における照明においても全体の照明と作業時のスポット照明の双方に対応でき、漁業用途における照明においては集魚灯として用いることにより深度の浅い領域及び深い領域の双方に有効であり且つエネルギー効率の良い照明装置として非常に有効であった。 Moreover, the form according to the present embodiment is effective in applications where both general illumination and spot illumination are required, such as illumination in a gymnasium, library, study room, office, tabletop, or product display place. Furthermore, the lighting at the construction site can handle both the overall lighting and the spot lighting at the time of work. In the lighting for fishery applications, it is effective for both shallow and deep areas by using it as a fish-collecting lamp. It was very effective as an efficient lighting device.
以上述べてきたように、本発明の光源装置及び光源装置を用いた植物の育成方法は、広域照射や広域波長の照射と光の強弱、点滅、スポットライト的な使用を含む制御に対応するとともに、必要な波長域の光量を得ることの出来る、特に植物工場への応用に適した光源装置及び光源装置を用いた植物の育成方法を実現するという利点があり、また、本発明は光源装置の用途を拡大し、利便性を向上させるとともに市場を拡大する効果があり、産業上の利用可能性は大であると言える。 As described above, the light source device of the present invention and the plant growth method using the light source device correspond to control including wide-area irradiation, wide-range wavelength irradiation, light intensity, blinking, and spotlight use. There is an advantage that a light source device capable of obtaining a light quantity in a necessary wavelength range, particularly suitable for application to a plant factory, and a method for growing a plant using the light source device are provided. It has the effect of expanding applications, improving convenience and expanding the market, and it can be said that the industrial applicability is great.
