従来例は、ＬＥＤ発光体として青色ＬＥＤに黄色の蛍光材料（フィルター）を施して白色光を生成する白色ＬＥＤが採用されているが、実際に従来例を使用した場合、黄色が強く出て水草の緑色が鮮やかに出ない（水草が健康に見えない）場合があることに鑑み本発明を完成させた。   In the conventional example, a white LED that generates a white light by applying a yellow fluorescent material (filter) to a blue LED as an LED light emitter is adopted. The present invention has been completed in view of the fact that the green color may not appear vividly (the aquatic plants may not look healthy).

即ち、本発明者は、ＬＥＤ発光体として、赤色光を発光する赤色発光素子部１Ａ，緑色光を発光する緑色発光素子部１Ｂ及び青色光を発光する青色発光素子部１Ｃを有するＬＥＤ発光体１を採用し、更に、この各素子部から発せられる光の波長を適宜調整するなど種々の実験を繰り返し行うことで、水草の鑑賞及び水草の育成に適した白色光を発生させるに至った。   That is, the present inventor has an LED light emitter 1 having a red light emitting element portion 1A that emits red light, a green light emitting element portion 1B that emits green light, and a blue light emitting element portion 1C that emits blue light. Furthermore, by repeating various experiments such as appropriately adjusting the wavelength of light emitted from each element part, white light suitable for appreciation of aquatic plants and cultivation of aquatic plants has been generated.

具体的には、本発明は、赤色発光素子部１Ａから発せられる光のピーク波長は、青色発光素子部１Ｃから発せられる光のピーク波長に対する７７％〜９７％に設定され、緑色発光素子部１Ｂから発せられる光のピーク波長は、青色発光素子部１Ｃから発せられる光のピーク波長に対する７０％〜９０％に設定されている。   Specifically, in the present invention, the peak wavelength of the light emitted from the red light emitting element portion 1A is set to 77% to 97% with respect to the peak wavelength of the light emitted from the blue light emitting element portion 1C, and the green light emitting element portion 1B. The peak wavelength of the light emitted from is set to 70% to 90% with respect to the peak wavelength of the light emitted from the blue light emitting element portion 1C.

実際に、本発明のＬＥＤ発光体１から水槽内の水草に対して上記白色光を照射したところ、水草の緑色が鮮やかに見え（水草が健康に見え）、しかも、水草の生育が良好となる（光合成が良好に行われるようになったと推察する。）ことを確認した。   Actually, when the white light is irradiated to the aquatic plants in the aquarium from the LED illuminant 1 of the present invention, the green color of the aquatic plants looks vivid (the aquatic plants look healthy), and the aquatic plants grow well. (It is presumed that photosynthesis has been carried out well.)

即ち、水草の緑色が鮮やかに見え且つ光合成が良好に行われる各波長を本発明者は実験により見い出した。   That is, the present inventor has found through experimentation each wavelength at which the green color of aquatic plants looks vivid and photosynthesis is performed satisfactorily.

The main body 5 may be a type that is placed on the upper part of the water tank 11 as disclosed in the Design Registration No. 1464444 instead of the hanging type.

本体部５は、天部材５Ａ，底部材５Ｂ，前部材５Ｃ，後部材５Ｄ，左部材５Ｅ及び右部材５Ｆで構成された中空構造体であり、各部材同士はビスを介して一体に連結される。   The main body 5 is a hollow structure composed of a top member 5A, a bottom member 5B, a front member 5C, a rear member 5D, a left member 5E, and a right member 5F, and the members are connected together via screws. The

天部材５Ａは、図１〜３に図示したように適宜な金属製の部材で形成した板状体であり、左右位置には吊り下げワイヤー10が連結される連結孔５ａが設けられている。   The top member 5A is a plate-like body formed of a suitable metal member as shown in FIGS. 1 to 3, and a connecting hole 5a to which the hanging wire 10 is connected is provided at the left and right positions.

従って、本実施例は、水槽台12に設けられるスタンド13から垂下される２本の吊り下げワイヤー10の下端部が天部材５Ａに連結され、水槽台12に載置される水槽11の上方位置に配される。符号５ａ’は後述する電源コード14を挿通する孔である。   Therefore, in this embodiment, the lower ends of the two suspension wires 10 suspended from the stand 13 provided on the water tank base 12 are connected to the top member 5A, and the upper position of the water tank 11 placed on the water tank base 12 Arranged.

従って、この各放熱板４により良好な放熱効果が得られ、しかも、この各放熱板４全てに多数の貫通孔４ａが形成されることで本体部５内に空気が流れる通気路が形成され、内部に空気がこもることなく良好な冷却効果が得られることになる。   Therefore, a good heat dissipation effect is obtained by each of the heat radiating plates 4, and a ventilation path through which air flows is formed in the main body portion 5 by forming a large number of through holes 4a in all of the heat radiating plates 4. A good cooling effect can be obtained without air being trapped inside.

本実施例は、後述するように多数のＬＥＤ発光体１（ＲＧＢ ＬＥＤ）を使用することになる為、発熱量は多く、この点おいても前述した良好な放熱効果を具備することは有意であり、ＬＥＤ発光体１の寿命を長くする構造として秀れている。   Since this embodiment uses a large number of LED light emitters 1 (RGB LEDs) as will be described later, it generates a large amount of heat, and in this respect as well, it is significant to have the above-described good heat dissipation effect. It is excellent as a structure that extends the life of the LED light emitter 1.

従って、本実施例では、赤色発光素子部１Ａから発せられる光のピーク波長は、青色発光素子部１Ｃから発せられる光のピーク波長に対する８７％に設定され、緑色発光素子部１Ｂから発せられる光のピーク波長は、青色発光素子部１Ｃから発せられる光のピーク波長に対する８０％に設定されており、更に、波長を調整して実験を進めたところ、この各数値の±１０％の範囲で同様の結果が得られた。   Therefore, in this embodiment, the peak wavelength of light emitted from the red light emitting element portion 1A is set to 87% with respect to the peak wavelength of light emitted from the blue light emitting element portion 1C, and the light emitted from the green light emitting element portion 1B. The peak wavelength is set to 80% with respect to the peak wavelength of the light emitted from the blue light emitting element portion 1C. Further, when the experiment was carried out with the wavelength adjusted, the same results were obtained in the range of ± 10% of these numerical values. Results were obtained.

よって、赤色発光素子部１Ａから発せられる光のピーク波長は、青色発光素子部１Ｃから発せられる光のピーク波長に対する７７％〜９７％に設定され、緑色発光素子部１Ｂから発せられる光のピーク波長は、青色発光素子部１Ｃから発せられる光のピーク波長に対する７０％〜９０％に設定される。   Therefore, the peak wavelength of the light emitted from the red light emitting element 1A is set to 77% to 97% with respect to the peak wavelength of the light emitted from the blue light emitting element 1C, and the peak wavelength of the light emitted from the green light emitting element 1B. Is set to 70% to 90% with respect to the peak wavelength of the light emitted from the blue light emitting element portion 1C.

本実施例は上述のように構成したから、赤色発光素子部１Ａから発せられる光のピーク波長は、青色発光素子部１Ｃから発せられる光のピーク波長に対する８７％に設定され、緑色発光素子部１Ｂから発せられる光のピーク波長は、青色発光素子部１Ｃから発せられる光のピーク波長に対する８０％に設定されている。   Since the present embodiment is configured as described above, the peak wavelength of the light emitted from the red light emitting element portion 1A is set to 87% with respect to the peak wavelength of the light emitted from the blue light emitting element portion 1C, and the green light emitting element portion 1B. The peak wavelength of the light emitted from is set to 80% with respect to the peak wavelength of the light emitted from the blue light emitting element portion 1C.

実際に、本実施例のＬＥＤ発光体１から水槽内の水草に対して上記白色光を照射したところ、水草の緑色が鮮やかに見え（水草が健康に見え）、しかも、水草の生育が良好となる（光合成が良好に行われるようになったと推察する。）。   Actually, when the white light is irradiated to the aquatic plants in the aquarium from the LED luminous body 1 of this example, the green color of the aquatic plants looks vivid (the aquatic plants look healthy), and the aquatic plants grow well. (It is assumed that photosynthesis has been carried out well.)

また、本実施例は、基板体２の下部に発光体１が多数設けられた発光部３を備え、基板体２の上部には複数の放熱板４が間隔を介して立設されているから、前述したＬＥＤ発光体１から発生する熱を良好に放熱することができる。   Further, the present embodiment includes a light emitting portion 3 in which a large number of light emitters 1 are provided at the bottom of the substrate body 2, and a plurality of heat radiating plates 4 are erected at intervals above the substrate body 2. The heat generated from the LED luminous body 1 can be radiated well.

また、本実施例は、放熱板４には多数の貫通孔４ａが設けられているから、より一層良好な放熱が行われることになる。   Further, in the present embodiment, since the heat radiating plate 4 is provided with a large number of through holes 4a, even better heat dissipation is performed.

尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。   Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
