また、従来行われてきた蛍光灯による照明に容易に代替する、発光ダイオードの発光装置がある(例えば、特許文献2参照)。
上掲特許文献2の蛍光灯器具対応型発光ダイオード発光装置は、蛍光灯の器具に直接接続可能な形状を有し、接続したときにその蛍光灯器具より供給される電源によって、1個または複数の発光ダイオードを点灯することを特徴とする。

Registration Utility No. 3083343

しかしながら、上掲特許文献1の冷凍ショーケースにおける照明装置は、蛍光灯から生じる発熱により冷凍ショーケース内の温度が上昇するという問題があった。そのため、常に冷却温度を高く設定しなければならず、多くの消費電力や稼働コストを必要とした。また、定期的に蛍光灯を交換しなければならず、手間や材料コストが嵩むという欠点もあった。  However, the illuminating device in the refrigerated showcase disclosed in Patent Document 1 has a problem that the temperature inside the refrigerated showcase rises due to heat generated from the fluorescent lamp. For this reason, the cooling temperature must always be set high, which requires a lot of power consumption and operating costs. In addition, the fluorescent lamps must be replaced periodically, which has the disadvantage of increasing labor and material costs.

また、上掲特許文献2の蛍光灯器具対応型発光ダイオード発光装置は、発光ダイオードから照射される光が一方向に直進するため、光の照射方向が限定されるという問題があった。そのことにより、蛍光灯から均一の照射が得られず、利便性が低下し、使用範囲も限定された。  In addition, the fluorescent light fixture-compatible light-emitting diode light-emitting device disclosed in Patent Document 2 has a problem in that the light irradiation direction is limited because light emitted from the light-emitting diode goes straight in one direction. As a result, uniform illumination could not be obtained from the fluorescent lamp, convenience was reduced, and the range of use was limited.

そこで本考案は上記の点に鑑み、照明器具自体から生じる発熱を少なくすることで、冷凍庫内の温度を上昇させることなく効率よく保冷することができ、さらに、消費電力や材料コストを極端に軽減することができる保冷装置用照明器具を提供することにある。  Therefore, in view of the above points, the present invention reduces the heat generated from the lighting fixture itself, thereby enabling efficient cooling without increasing the temperature in the freezer, and extremely reducing power consumption and material costs. An object of the present invention is to provide a lighting apparatus for a cold insulator that can be used.

上記問題を解決するために本考案の保冷装置用照明器具は、冷蔵庫、冷凍庫、冷凍車、冷凍ショーケース等に具備される保冷装置用照明器具であって、該保冷装置用照明器具は、先端に凹部を形成した発光ダイオードを、透光管内に縦列状態に複数連結したことを特徴とする。  In order to solve the above problems, a lighting device for a cold insulation device of the present invention is a lighting device for a cold insulation device provided in a refrigerator, a freezer, a freezer car, a freezer showcase, etc. A plurality of light emitting diodes having recesses formed therein are connected in tandem in a light-transmitting tube.

また、前記透光管の周囲に外管体を配設させた。  Further, an outer tube was disposed around the light transmitting tube.

また、前記発光ダイオードは、前記透光管内の中央部分で凹部が対向する状態に配設されている。  In addition, the light emitting diode is disposed in a state where the concave portion faces the central portion in the light transmitting tube.

また、前記発光ダイオードの凹部をV字状に形成した。  Further, the concave portion of the light emitting diode was formed in a V shape.

またさらに、前記保冷装置用照明器具に反射板を具備した。  Still further, the cold insulator lighting fixture is provided with a reflector.

先端に凹部を形成した発光ダイオードを、透光管内に縦列状態に複数連結させたことで、透光管の側面方向に効率よく照射させることができ、保冷装置用照明器具を低コストで高輝度に発光させることができる。  By connecting a plurality of light emitting diodes with recesses at the tip in a tandem state in the light-transmitting tube, it is possible to efficiently irradiate the side surface of the light-transmitting tube, and the luminaire for the cold insulation device has high brightness at low cost. Can emit light.

また、光源として0.1W以下の発光ダイオードを使用することにより、照明器具自体から生じる発熱を少なくすることができ、冷凍庫内の温度を上昇させることがない。また、照明器具の交換を低減することで、手間や材料コストを極端に軽減することができる。  Further, by using a light emitting diode of 0.1 W or less as a light source, heat generated from the lighting fixture itself can be reduced, and the temperature in the freezer is not increased. In addition, it is possible to drastically reduce labor and material costs by reducing replacement of lighting fixtures.

1 is a general view of a lighting fixture for a cold insulation device, FIG. 2 is a perspective view of a light emitting diode, FIG. 3 is a sectional view showing a light emitting state of the light emitting diode, FIG. 4 is an array state of light emitting diodes, and FIG. FIG. 6 shows a light emitting diode in which concave portions are formed in a conical shape, FIG. 7 shows a light emitting diode in which concave portions are formed in a pyramid shape, and FIG. 8 shows a concave portion formed in a polyhedral cone shape having vertical grooves.

本考案の保冷装置用照明器具は、冷蔵庫、冷凍庫、冷凍車、冷凍ショーケース等の保冷装置に具備されるもので、照明器具自体から発せられる発熱を少なくすることで、冷凍庫内の温度を上昇させることを防ぎ、消費エネルギーを極力軽減することができることを特徴とする。  The lighting fixture for a cold insulation device of the present invention is provided in a cold insulation device such as a refrigerator, a freezer, a freezer car, a freezer showcase, etc., and the temperature inside the freezer is increased by reducing the heat generated from the lighting fixture itself. It is characterized by being able to prevent the energy consumption from being reduced as much as possible.

図1に示す保冷装置用照明器具1は、先端に凹部11を形成した発光ダイオード10を、透光管2内に縦列状態に複数連結したことを特徴とする。  The luminaire 1 for a cold insulator shown in FIG. 1 is characterized in that a plurality of light emitting diodes 10 each having a concave portion 11 formed at the tip thereof are connected in a tandem state in the light-transmitting tube 2.

図2に示す発光ダイオード10は、レンズ部12と、レンズ部12内に配設される発光部13と、発光部13へ電力を供給する一対のリード14とで構成されている。また特に、発光ダイオード10のレンズ部12の先端には凹部11が形成されている。  The light emitting diode 10 shown in FIG. 2 includes a lens unit 12, a light emitting unit 13 disposed in the lens unit 12, and a pair of leads 14 that supply power to the light emitting unit 13. In particular, a concave portion 11 is formed at the tip of the lens portion 12 of the light emitting diode 10.

また前記凹部11を、V字状に形成することが望ましい。前記凹部11をV字状に形成することで、図3に示すように、発光部13から発光された光は、一部が直進すると共に、他の光は凹部11にて側方に屈折される。  Moreover, it is desirable to form the said recessed part 11 in V shape. By forming the concave portion 11 in a V shape, as shown in FIG. 3, a part of the light emitted from the light emitting portion 13 goes straight, and the other light is refracted laterally by the concave portion 11. The

透光管2は、透明樹脂もしくはガラス等の光透過性を有する素材からなり、前記発光ダイオード10を縦列状態に複数収容することができる径を呈する細管状に形成されている。また、前記透光管2の内壁に蛍光剤を塗布してもよい。  The light-transmitting tube 2 is made of a light-transmitting material such as transparent resin or glass, and is formed in a thin tubular shape having a diameter capable of accommodating a plurality of the light-emitting diodes 10 in a tandem state. Further, a fluorescent agent may be applied to the inner wall of the translucent tube 2.

また、前記透光管2の周囲に外管体3を配設させてもよい。外管体3はガラス、樹脂等で筒状に形成されている。また前記外管体3は図中、直状に形成されているがこれに限らず、環状、U字状等のさまざまな形状に形成してもよい。  Further, an outer tube 3 may be disposed around the light transmitting tube 2. The outer tube 3 is formed in a cylindrical shape with glass, resin or the like. In addition, the outer tube body 3 is formed in a straight shape in the figure, but is not limited thereto, and may be formed in various shapes such as an annular shape and a U shape.

また他の好適例として、前記発光ダイオード10は、前記透光管2の中央部分で凹部11が対向する状態に配設することが望ましい。発光ダイオード10の凹部11を透光管2の中央部分で対向するように配設することで、発光ダイオード10から直進する光は、透光管2の中央部分で高輝度に照射されると共に、他の部分では、凹部11により透光管2の側方に照射される。  As another preferred example, it is desirable that the light emitting diode 10 is disposed in a state where the concave portion 11 faces the central portion of the light transmitting tube 2. By disposing the concave portion 11 of the light emitting diode 10 so as to face the central portion of the light-transmitting tube 2, light traveling straight from the light-emitting diode 10 is irradiated with high luminance at the central portion of the light-transmitting tube 2, In other portions, the side of the light-transmitting tube 2 is irradiated by the recess 11.

また、前記発光ダイオード10は通常、図4に示すように、凹部11が同位置になるように配設されているが、図5に示すように、凹部11の配置角度が異なる状態(水平方向に90°相違)で配列させてもよい。そのことにより、発光部13から発光された光は、凹部11にて側方に、かつ異方向側方に照射することができ、透光管2からの光を均一に照射させることが可能になる。  In addition, the light emitting diode 10 is usually arranged so that the concave portion 11 is located at the same position as shown in FIG. 4, but the arrangement angle of the concave portion 11 is different (horizontal direction) as shown in FIG. May be arranged at 90 ° difference). As a result, the light emitted from the light emitting unit 13 can be irradiated laterally and in a different direction in the concave portion 11, and the light from the translucent tube 2 can be uniformly irradiated. Become.

さらに、本考案の保冷装置用照明器具1は、0.1W以下の発光ダイオード10を縦列状態に複数連結することが望ましい。発光ダイオード10を0.1W以下の電力としたことで、消費コストを極端に下げると共に、ほぼ無発熱の照明器具を実現することができる。  Furthermore, it is preferable that the lighting fixture 1 for a cold insulation device of the present invention connects a plurality of light emitting diodes 10 of 0.1 W or less in a tandem state. By making the light emitting diode 10 have a power of 0.1 W or less, it is possible to extremely reduce the consumption cost and realize a substantially non-heated lighting fixture.

次に、発光ダイオード10の凹部11における他の形状を図6乃至図8に基づいて説明する。
図6は、円錐状に形成した凹部15を示す。発光ダイオード10の凹部を円錐状としたことで、発光部13から照射される光は、均一状態で前面および側面に照射することができる。
Next, another shape of the concave portion 11 of the light emitting diode 10 will be described with reference to FIGS.
FIG. 6 shows the recess 15 formed in a conical shape. Since the concave portion of the light emitting diode 10 is conical, the light emitted from the light emitting unit 13 can be irradiated to the front surface and the side surface in a uniform state.

図7は角錐状に形成した凹部16を示す。また前記凹部16は、図中、六角錐に形成されているが、これに限らず、三角錐、四角錐、五角錐等、さまざまな多角錐に形成することができる。前記角錐状に形成することで、発光部13からの光を任意の角度に、広角、且つ広範囲に外部に照射することができる。  FIG. 7 shows the recess 16 formed in a pyramid shape. Moreover, although the said recessed part 16 is formed in the hexagonal pyramid in the figure, it is not restricted to this, It can form in various polygonal pyramids, such as a triangular pyramid, a quadrangular pyramid, and a pentagonal pyramid. By forming in the shape of the pyramid, the light from the light emitting unit 13 can be irradiated to the outside at an arbitrary angle, a wide angle, and a wide range.

図8は多面錐状に形成した凹部17を示す。前記凹部17は、星型の溝を設けることにより形成される。前記凹部17を多面錐状に形成することで、発光体13からの光を円周多方向に広角に、且つ広範囲に外部へ照射させることができる。  FIG. 8 shows a recess 17 formed in a polyhedral cone shape. The concave portion 17 is formed by providing a star-shaped groove. By forming the concave portion 17 in a polyhedral conical shape, light from the light emitter 13 can be radiated to the outside in a wide angle and in a wide range in the circumferential direction.

また他の好適例として、前記保冷装置用照明器具1に反射板4を具備した。かかる反射板4は反射効率の高いアルミ等で形成されている。前記保冷装置用照明器具1に反射板4を具備したことで、透光管2から照射される光を、より高輝度に、かつ効率よく外部へ照射させることができる。  As another suitable example, the reflector 1 is provided in the lighting apparatus 1 for a cold insulator. The reflection plate 4 is made of aluminum having high reflection efficiency. Since the light fixture 1 for the cold insulator is provided with the reflection plate 4, the light emitted from the translucent tube 2 can be radiated to the outside with higher luminance and efficiency.

次に、本考案の保冷装置用照明器具1の使用状態を図9および図10に基づいて説明する。
図9は、冷凍ショーケース20に保冷装置用照明器具1を装着した状態を示す。冷凍ショーケース20には冷凍装置21が具備されており、ケース内の冷凍商品を一定温度で保冷している。冷凍ショーケース20に本考案の保冷装置用照明器具1を装着したことで、照明器具自体から生じる発熱は殆どなく、エネルギーのロスが少なく、消費エネルギーを極力軽減することができる。なお、透光管2の内壁に塗布する蛍光物質の色彩を変更することで、冷凍食品および食品の外観を向上させることも可能になる。
Next, the use state of the lighting fixture 1 for cold insulation apparatus of this invention is demonstrated based on FIG. 9 and FIG.
FIG. 9 shows a state where the refrigeration equipment lighting fixture 1 is attached to the refrigerated showcase 20. The refrigeration showcase 20 is provided with a refrigeration apparatus 21 and keeps the frozen products in the case at a constant temperature. By mounting the refrigeration equipment lighting fixture 1 of the present invention on the frozen showcase 20, there is almost no heat generated from the lighting fixture itself, there is little energy loss, and energy consumption can be reduced as much as possible. In addition, it becomes possible to improve the external appearance of frozen food and food by changing the color of the fluorescent substance applied to the inner wall of the translucent tube 2.

図10は、冷凍庫22に本考案の保冷装置用照明器具1を装着した状態を示す。通常、冷凍庫22は、冷凍装置23にて非常に低い状態で冷凍食品を保管・管理する場所である。前記冷凍庫22に保冷装置用照明器具1を装着することで、冷凍庫22の温度を上昇させることなく、保冷状態を効率よく維持することができる。また、保冷装置用照明器具1から照射させる高輝度の光により、冷凍庫22内において明るく好適な条件で作業することができる。  FIG. 10 shows a state where the refrigerator 1 of the present invention is mounted on the freezer 22. Usually, the freezer 22 is a place where frozen food is stored and managed in a very low state in the freezer 23. By mounting the cold insulator lighting fixture 1 on the freezer 22, the cold state can be efficiently maintained without increasing the temperature of the freezer 22. In addition, the high-intensity light irradiated from the cold-instrument lighting fixture 1 can be operated in a bright and suitable condition in the freezer 22.

なお、本考案の保冷装置用照明器具の利用範囲は、冷蔵庫、冷凍室、冷凍車、冷凍ショーケース等の保冷装置に限定されるものではなく、一般のショーケース、室内外の照明灯、看板灯、常夜灯等、さまざまな分野で広範囲に使用できることは言うまでもない。  Note that the scope of use of the lighting apparatus for a cold insulation device of the present invention is not limited to a cold insulation device such as a refrigerator, a freezer room, a freezer car, or a freezer showcase, but a general showcase, indoor / outdoor lighting lamps, and signboards It goes without saying that it can be used in a wide range of fields such as lights and night lights.
