以下、本発明のエレベータ用照明装置の好適な実施の形態につき図面を用いて説明する。   Hereinafter, preferred embodiments of an elevator lighting device according to the present invention will be described with reference to the drawings.

実施の形態1.
図1は、本発明の実施の形態1のエレベータ用照明装置におけるかご室天井部の斜視図である。図1おけるかご室天井部は、吊天井1、天蓋部2、および照明板3で構成されており、かご室の側面は、側板4が設けられている。
Embodiment 1 FIG.
FIG. 1 is a perspective view of a ceiling part of a cab in the elevator lighting device according to Embodiment 1 of the present invention. 1 includes a suspended ceiling 1, a canopy 2, and a lighting plate 3. A side plate 4 is provided on a side surface of the cab.

また、図2は、本発明の実施の形態1における図1で示したエレベータ用照明装置の縦方向断面図である。本実施の形態1におけるエレベータ用照明装置は、吊天井1、天蓋部2、および照明板3で囲まれたかご室天井部内に収納されており、板状反射板5、山型状反射板6、インバータ照明器具7、円形蛍光灯8、および遮光板9を含む構成となっている。ただし、遮光板9を含まない構成をすることも可能である。   FIG. 2 is a longitudinal sectional view of the elevator illuminating device shown in FIG. 1 according to Embodiment 1 of the present invention. The elevator illuminating device in the first embodiment is housed in a cab ceiling enclosed by a suspended ceiling 1, a canopy 2 and an illuminating plate 3, and includes a plate-shaped reflecting plate 5 and a mountain-shaped reflecting plate 6 The inverter lighting fixture 7, the circular fluorescent lamp 8, and the light shielding plate 9 are included. However, a configuration not including the light shielding plate 9 is also possible.

図2に示すように、インバータ照明器具7は、板状反射板5および山型状反射板6で覆われるように配置されている。ここで、板状反射板5および山型状反射板6は、円形蛍光灯8から発生する熱を遮断する効果、および円形蛍光灯8から発生する光を反射する効果を兼ね備えている。このような反射板の熱遮断効果により、蛍光灯の熱を嫌うインバータ照明器具を蛍光灯と近接して設置できるとともに、光反射効果により、光ムラを向上させることができる。   As shown in FIG. 2, the inverter lighting fixture 7 is arranged so as to be covered with the plate-like reflector 5 and the mountain-like reflector 6. Here, the plate-shaped reflecting plate 5 and the mountain-shaped reflecting plate 6 have both the effect of blocking the heat generated from the circular fluorescent lamp 8 and the effect of reflecting the light generated from the circular fluorescent lamp 8. Due to such a heat shielding effect of the reflecting plate, an inverter illuminator that dislikes the heat of the fluorescent lamp can be installed close to the fluorescent lamp, and light unevenness can be improved by the light reflecting effect.

図3は、本発明の実施の形態1におけるエレベータ用照明装置を、図2における矢印Aの方向から見た斜視図である。なお、図3の斜視図は、エレベータ用照明装置の内部構造が分かるように、照明板3を外した状態を示している。図3に示すように、複数の円形蛍光灯8が配置されており、この円形蛍光灯8の光を反射するように、円形蛍光灯8の間には山型状反射板6が取り付けられ、四周部分には板状反射板5が取り付けられている。   FIG. 3 is a perspective view of the elevator illuminating device according to Embodiment 1 of the present invention as viewed from the direction of arrow A in FIG. In addition, the perspective view of FIG. 3 has shown the state which removed the illuminating plate 3 so that the internal structure of the illuminating device for elevators can be understood. As shown in FIG. 3, a plurality of circular fluorescent lamps 8 are arranged, and a mountain-shaped reflector 6 is attached between the circular fluorescent lamps 8 so as to reflect the light of the circular fluorescent lamps 8. A plate-like reflecting plate 5 is attached to the four peripheral portions.

次に、図4は、本発明の実施の形態1におけるエレベータ用照明装置の一部分の拡大図であり、図3におけるC部を拡大したものである。なお、図4の拡大図では、内部構成をわかりやすくするために、板状反射板5の一部をカットして示している。図4に示すように、本実施の形態1におけるエレベータ用照明装置では、板状反射板5が四周部分に配置されており、インバータ照明器具7がこれら板状反射板5によって覆われている。   Next, FIG. 4 is an enlarged view of a portion of the elevator illumination apparatus according to Embodiment 1 of the present invention, and is an enlarged view of part C in FIG. In addition, in the enlarged view of FIG. 4, in order to make an internal structure easy to understand, a part of the plate-like reflecting plate 5 is cut and shown. As shown in FIG. 4, in the elevator illuminating device according to the first embodiment, the plate-like reflecting plate 5 is disposed in the four-circumferential portion, and the inverter lighting fixture 7 is covered with these plate-like reflecting plates 5.

次に、図5は、本発明の実施の形態1におけるエレベータ用照明装置の断面拡大図であり、図2におけるB部を拡大して示したものである。この図5は、山型状反射板6および板状反射板5による光反射効果を説明するための図であり、円形蛍光灯8の光の方向が、複数の矢印として表されている。円形蛍光灯8から直接、照明板3へ向かう光だけでなく、山型状反射板6および板状反射板5で反射されて、間接的に照明板3へ向かう光も存在していることがわかる。   Next, FIG. 5 is an enlarged cross-sectional view of the elevator illuminating device according to Embodiment 1 of the present invention, and is an enlarged view of portion B in FIG. FIG. 5 is a view for explaining the light reflection effect by the mountain-shaped reflector 6 and the plate-like reflector 5, and the light directions of the circular fluorescent lamp 8 are represented as a plurality of arrows. Not only light directed directly from the circular fluorescent lamp 8 toward the illumination plate 3 but also light reflected by the mountain-shaped reflector 6 and the plate-like reflector 5 and indirectly directed to the illumination plate 3 exists. Recognize.

以上のように、実施の形態1によれば、山型状反射板および板状反射板を設置することで、インバータ照明器具を四周部および蛍光灯間に配置させることができ、インバータ照明器具と円形蛍光灯の位置を近づけることができる。この結果、天井の四周部分の暗さを軽減できる。   As described above, according to the first embodiment, by installing the mountain-shaped reflector and the plate-like reflector, the inverter lighting apparatus can be arranged between the four circumferences and the fluorescent lamp, The position of the circular fluorescent lamp can be brought closer. As a result, the darkness of the four-round portion of the ceiling can be reduced.

さらに、光の拡散を多くし、円形蛍光灯から照明板に達する光量を均一に拡散させることができ、エレベータかご内から見上げた光ムラを軽減することができるとともに、意匠性の向上を図ることもできる。   Furthermore, the diffusion of light is increased, the amount of light reaching the illumination plate from the circular fluorescent lamp can be uniformly diffused, light unevenness looking up from inside the elevator car can be reduced, and the design is improved. You can also.

さらに、板状反射板内および山型状反射板内にインバータ照明器具を設置することにより、円形蛍光灯の熱からの遮熱効果が得られ、インバータ照明器具を設置する際に、蛍光灯からの熱の影響を考える必要がなくなる。この結果、従来よりも円形蛍光灯を吊天井の側面近くまで配置できる、あるいは円形蛍光灯を互いにより近接させて配置できるなど、レイアウトの自由度を向上させることも可能となる。   Furthermore, by installing the inverter lighting fixture in the plate-like reflector and the mountain-shaped reflector, the heat shielding effect from the heat of the circular fluorescent lamp can be obtained. When installing the inverter lighting fixture, There is no need to consider the effects of heat. As a result, it is possible to improve the degree of freedom in layout, such as arranging circular fluorescent lamps closer to the side of the suspended ceiling than before, or arranging circular fluorescent lamps closer to each other.

なお、上述の説明では、円形蛍光灯を用いる場合を説明したが、本発明のエレベータ用照明装置は、円形でない蛍光灯を用いることも可能であり、同様の効果を得ることができる。   In the above description, the case where a circular fluorescent lamp is used has been described. However, the elevator illumination apparatus of the present invention can also use a non-circular fluorescent lamp, and the same effect can be obtained.
