Description

この発明は、ＬＥＤの発光によりかご内の照明を行うエレベータのかご内照明装置に関するものである。   The present invention relates to an elevator car illumination device that performs illumination in a car by light emission of an LED.

従来、長寿命化や省エネ化を図るために、複数のＬＥＤを発光させてかご内の照明を行うエレベータのかご内照明装置が知られている。各ＬＥＤは、光を拡散させる保護板により、まとめて覆われている（特許文献１参照）。   2. Description of the Related Art Conventionally, in order to extend the life and save energy, an elevator car lighting device is known that emits light from a plurality of LEDs to illuminate the car. Each LED is collectively covered with a protective plate that diffuses light (see Patent Document 1).

特開２００４−３３８８２５号公報JP 2004-338825 A

しかし、ＬＥＤの指向性は、通常の蛍光灯等に比べて極めて強い指向性となっているので、各ＬＥＤからの光を保護板によって拡散させたとしても、保護板の位置によっては、各ＬＥＤの配置に応じた明暗が保護板に明確に生じてしまい、保護板全体が均等に光っているかのような柔らかい印象を与える意匠とすることができなくなってしまう。これにより、照明装置の意匠性が低下してしまう。   However, the directivity of the LED is very strong compared to ordinary fluorescent lamps, etc. Even if the light from each LED is diffused by the protective plate, depending on the position of the protective plate, each LED Brightness and darkness corresponding to the arrangement of the protective plate is clearly generated in the protective plate, and it becomes impossible to make a design that gives a soft impression as if the entire protective plate is shining evenly. Thereby, the designability of an illuminating device will fall.

この発明は、上記のような課題を解決するためになされたものであり、意匠性の向上を図ることができるエレベータのかご内照明装置を得ることを目的とする。   The present invention has been made in order to solve the above-described problems, and an object thereof is to obtain an elevator car lighting device capable of improving the design.

この発明によるエレベータのかご内照明装置は、互いに間隔を置いて配置された複数のＬＥＤを有し、各ＬＥＤからの光をかご内に照射する光源装置、及び各ＬＥＤよりもかごの内側に配置され、各ＬＥＤからかご内への光を散乱させる照明カバーを備え、各ＬＥＤは、光軸に対する角度が２０度以下である領域内において、光軸上での光度に対する相対光度が８０％以上となる指向特性を有しており、各ＬＥＤ間のピッチＸ（ｍｍ）と、各ＬＥＤ及び照明カバー間の距離Ｙ（ｍｍ）との関係は、Ｙ≧０．９Ｘ＋９を満たす関係である。   An elevator car lighting device according to the present invention includes a plurality of LEDs arranged at intervals from each other, a light source device that irradiates light from each LED into the car, and a lighter device that is disposed inside the car than each LED. Each LED includes an illumination cover that scatters light from the LEDs into the cage, and each LED has a relative luminous intensity of 80% or more with respect to the luminous intensity on the optical axis in an area where the angle with respect to the optical axis is 20 degrees or less. The relationship between the pitch X (mm) between the LEDs and the distance Y (mm) between the LEDs and the illumination cover is a relationship satisfying Y ≧ 0.9X + 9.

この発明によるエレベータのかご内照明装置では、光軸に対する角度が２０度以下である領域内で相対光度が８０％以上となる指向特性を各ＬＥＤが持ち、各ＬＥＤ間のピッチＸ（ｍｍ）と、各ＬＥＤ及び照明カバー間の距離Ｙ（ｍｍ）との関係が、Ｙ≧０．９Ｘ＋９を満たす関係であるので、互いに隣り合うＬＥＤについて光度の高い範囲同士が重なることを避けながら、光度の低い範囲同士を重ねることができ、照明カバーの位置での光度を均等に近づけることができる。従って、照明カバーにおいて明暗が生じることを抑制することができ、照明カバー全体が均等に光っているかのような柔らかい印象を与える意匠に近づけることができる。これにより、照明装置の意匠性の向上を図ることができる。また、各ＬＥＤの指向特性が一般のＬＥＤの指向特性の範囲内に設定されているので、各ＬＥＤのコストの低減化を図ることができる。   In the elevator car lighting device according to the present invention, each LED has a directivity characteristic in which the relative luminous intensity is 80% or more in an area where the angle with respect to the optical axis is 20 degrees or less, and the pitch X (mm) between the LEDs is Since the relationship between the distance Y (mm) between each LED and the illumination cover is a relationship satisfying Y ≧ 0.9X + 9, the light intensity is low while avoiding overlapping of the high light intensity ranges of the adjacent LEDs. The ranges can be overlapped, and the luminous intensity at the position of the lighting cover can be made close to each other. Therefore, it is possible to suppress the occurrence of light and darkness in the lighting cover, and it is possible to approach a design that gives a soft impression as if the entire lighting cover is shining evenly. Thereby, the designability of an illuminating device can be improved. Moreover, since the directivity of each LED is set within the range of the directivity of general LEDs, the cost of each LED can be reduced.

FIG. 3 is a front view when the car ceiling 4 is viewed from the car 1 in FIG. Further, FIG. 4 is a front view showing a state when the illumination cover is removed from the car ceiling 4 of FIG. In the figure, the car ceiling 4 is arranged above the opening panel 5 with a ceiling panel 6 provided with an opening 5 (that is, on the outside of the car 1 with respect to the opening 5) and attached to the ceiling panel 6. And a canopy (illumination box) 7 (FIG. 2). The car ceiling 4 is provided with a car lighting device (hereinafter simply referred to as “illuminating device”) 8 for illuminating the car 1.

天井パネル６の中央部には、図２に示すように、かご１の内側へ窪んだ凹部９が設けられている。また、天井パネル６は、凹部９の周囲に水平に配置された天井上板部１０と、天井上板部１０よりも低い位置に配置され、凹部９の底面を形成する天井下板部１１と、天井上板部１０及び天井下板部１１間を結び、凹部９の内側面を形成する天井垂直板部１２とを有している。開口部５は、天井下板部１１に設けられている。この例では、開口部５の形状は、図３及び図４に示すように、縦寸法が６００（ｍｍ）、横寸法が６００（ｍｍ）の正方形とされている。   As shown in FIG. 2, a recess 9 that is recessed toward the inside of the car 1 is provided at the center of the ceiling panel 6. The ceiling panel 6 includes a ceiling upper plate 10 that is horizontally disposed around the recess 9, and a ceiling lower plate 11 that is disposed at a position lower than the ceiling upper plate 10 and forms the bottom surface of the recess 9. The ceiling upper plate portion 10 and the ceiling lower plate portion 11 are connected to each other and have a ceiling vertical plate portion 12 that forms the inner surface of the recess 9. The opening 5 is provided in the ceiling lower plate part 11. In this example, the shape of the opening 5 is a square having a vertical dimension of 600 (mm) and a horizontal dimension of 600 (mm), as shown in FIGS.

天蓋７は、凹部９内に配置されている。また、天蓋７は、天井下板部１１に取り付けられた縁部１３と、縁部１３の上端部に設けられ、開口部５の上方で水平に配置された板状の天蓋本体１４とを有している。なお、この例では、凹部９の深さ寸法が５０（ｍｍ）とされている。   The canopy 7 is disposed in the recess 9. The canopy 7 includes an edge portion 13 attached to the ceiling lower plate portion 11 and a plate-like canopy main body 14 provided at the upper end portion of the edge portion 13 and disposed horizontally above the opening portion 5. doing. In this example, the depth dimension of the recess 9 is 50 (mm).

照明装置８は、放熱用の取付板１５を介して天蓋本体１４にそれぞれ取り付けられた複数（この例では、９個）のＬＥＤユニット（光源装置）１６と、各ＬＥＤユニット１６の下方（即ち、各ＬＥＤユニット１６よりもかご１の内側の位置）に配置され、開口部５を塞ぐ照明カバー１７とを有している。   The illuminating device 8 includes a plurality (9 in this example) of LED units (light source devices) 16 attached to the canopy main body 14 via a heat radiating attachment plate 15, and below each LED unit 16 (ie, The lighting cover 17 is disposed at a position inside the car 1 with respect to each LED unit 16 and closes the opening 5.

各ＬＥＤユニット１６は、天蓋本体１４に沿って水平方向へ並べられている。また、各ＬＥＤユニット１６は、図４に示すように、かご１内から見たときに開口部５の範囲内に収まるように配置されている。この例では、開口部５の縦方向に３列、開口部５の横方向に３列の合計９個のＬＥＤユニット１６が均等に配置されている。   The LED units 16 are arranged in the horizontal direction along the canopy main body 14. Moreover, each LED unit 16 is arrange | positioned so that it may be settled in the range of the opening part 5 when it sees from the cage | basket | car 1, as shown in FIG. In this example, a total of nine LED units 16 in three rows in the vertical direction of the openings 5 and three rows in the horizontal direction of the openings 5 are equally arranged.

各ＬＥＤユニット１６は、図２に示すように、共通の取付板１５を介して天蓋本体１４に取り付けられている。取付板１５の材料としては、例えば、アルミニウム等の金属や熱伝導率の高い樹脂等が用いられている。各ＬＥＤユニット１６で発生した熱は、取付板１５を通して天蓋７へ伝わり、外気へ放散される。   As shown in FIG. 2, each LED unit 16 is attached to the canopy main body 14 via a common attachment plate 15. As the material of the mounting plate 15, for example, a metal such as aluminum or a resin having a high thermal conductivity is used. The heat generated in each LED unit 16 is transmitted to the canopy 7 through the mounting plate 15 and dissipated to the outside air.

ここで、図５は、図４のＬＥＤユニット１６を示す正面図である。各ＬＥＤユニット１６は、基板１８と、基板１８に搭載された複数のＬＥＤ１９とを有している。   Here, FIG. 5 is a front view showing the LED unit 16 of FIG. Each LED unit 16 includes a substrate 18 and a plurality of LEDs 19 mounted on the substrate 18.

基板１８には、ＬＥＤユニット１６を取付板１５にねじで取り付けるための複数の取付穴２０と、各ＬＥＤ１９に電気的に接続された抵抗２１とが設けられている。また、基板１８には、電源及びＬＥＤユニット１６間の電気的接続と、各ＬＥＤユニット１６間の電気的接続とを個別に行うための複数のコネクタ２２も設けられている。   The substrate 18 is provided with a plurality of mounting holes 20 for mounting the LED unit 16 to the mounting plate 15 with screws, and resistors 21 electrically connected to the LEDs 19. The board 18 is also provided with a plurality of connectors 22 for individually making electrical connection between the power source and the LED units 16 and electrical connection between the LED units 16.

各ＬＥＤ１９は、給電を受けることにより発光する。各ＬＥＤ１９からの光は、照明カバー１７を通ってかご１内に照射される。また、各ＬＥＤ１９は、基板１８の表面（即ち、天蓋本体１４に沿った共通の平面（所定の平面））に沿って互いに間隔を置いて配置されている。各ＬＥＤ１９は、等間隔に配置されている。   Each LED 19 emits light when it receives power. Light from each LED 19 is irradiated into the car 1 through the illumination cover 17. Further, the LEDs 19 are arranged at intervals from each other along the surface of the substrate 18 (that is, a common plane (predetermined plane) along the canopy main body 14). Each LED 19 is arranged at equal intervals.

この例では、基板１８の形状は、縦寸法が１９８（ｍｍ）、横寸法が１９８（ｍｍ）の正方形とされている。また、この例では、基板１８の縦方向に６列、基板１８の横方向に６列の合計３６個のＬＥＤ１９が共通の基板１８に搭載されている。共通の基板１８に搭載された各ＬＥＤ１９間の間隔（ピッチ）Ｘ（ｍｍ）は、３３．５（ｍｍ）とされている。また、共通の基板１８に搭載された各ＬＥＤ１９のうち、基板１８の最外郭に配置されたＬＥＤ１９と基板１８の縦辺又は横辺との間の距離Ａ（ｍｍ）は、各ＬＥＤ１９間のピッチのほぼ半分の距離、即ち１５．７（ｍｍ）とされている。これにより、互いに隣り合う基板１８の最外郭にそれぞれ配置されたＬＥＤ１９間のピッチも、共通の基板１８に搭載された各ＬＥＤ１９間のピッチと同一のピッチ、即ち３３．５（ｍｍ）になっている。   In this example, the shape of the substrate 18 is a square having a vertical dimension of 198 (mm) and a horizontal dimension of 198 (mm). In this example, a total of 36 LEDs 19, 6 rows in the vertical direction of the substrate 18 and 6 rows in the horizontal direction of the substrate 18, are mounted on the common substrate 18. An interval (pitch) X (mm) between the LEDs 19 mounted on the common substrate 18 is 33.5 (mm). Further, among the LEDs 19 mounted on the common substrate 18, the distance A (mm) between the LEDs 19 arranged on the outermost side of the substrate 18 and the vertical side or the horizontal side of the substrate 18 is the pitch between the LEDs 19. The distance is approximately half of the distance, that is, 15.7 (mm). As a result, the pitch between the LEDs 19 arranged on the outermost sides of the substrates 18 adjacent to each other is also the same as the pitch between the LEDs 19 mounted on the common substrate 18, that is, 33.5 (mm). Yes.

照明カバー１７は、透光性を持つ平板である。また、照明カバー１７は、図２に示すように、各基板１８と平行に配置されている。従って、各ＬＥＤ１９のいずれについても、照明カバー１７との間の距離が同一の距離とされている。さらに、照明カバー１７は、各ＬＥＤ１９からかご１内への光を散乱させる。これにより、各ＬＥＤ１９からの光によって照明カバー１７に生じる明暗の境界が曖昧になる。   The illumination cover 17 is a flat plate having translucency. Moreover, the illumination cover 17 is arrange | positioned in parallel with each board | substrate 18, as shown in FIG. Therefore, the distance between each LED 19 and the illumination cover 17 is the same. Further, the illumination cover 17 scatters light from each LED 19 into the car 1. Thereby, the light / dark boundary produced in the illumination cover 17 by the light from each LED 19 becomes ambiguous.

照明カバー１７は、透明又は半透明の材料（例えば樹脂やガラス等）により構成されている。また、この例では、照明カバー１７の色が乳白色とされている。   The illumination cover 17 is made of a transparent or translucent material (for example, resin or glass). In this example, the color of the illumination cover 17 is milky white.

図６は、図２の照明装置８を示す拡大図である。各ＬＥＤ１９の光軸は、互いに平行になっている。また、各ＬＥＤ１９の光軸は、照明カバー１７に対してそれぞれ垂直になっている。   FIG. 6 is an enlarged view showing the illumination device 8 of FIG. The optical axes of the LEDs 19 are parallel to each other. The optical axis of each LED 19 is perpendicular to the illumination cover 17.

ＬＥＤ１９からの光は、光軸に対して７５度以下の領域内で照射される。即ち、各ＬＥＤ１９からの光の拡散角は、１３０度となっている。また、光度は、ＬＥＤ１９の光軸上で最も高く、光軸上から周辺に向かうほど連続的に低下する。この例では、光軸上での光度を１００％とすると、８０％以上の光度となる領域は、光軸に対する角度が２０度以下の領域（即ち、光軸を中心とする４０度の角度領域内）とされている。即ち、各ＬＥＤ１９は、光軸に対する角度が２０度以下の領域内において、光軸上での光度に対する光度の比率（相対光度）が８０％以上となる指向特性を有している。   Light from the LED 19 is irradiated in a region of 75 degrees or less with respect to the optical axis. That is, the diffusion angle of light from each LED 19 is 130 degrees. The luminous intensity is highest on the optical axis of the LED 19, and continuously decreases from the optical axis toward the periphery. In this example, assuming that the luminous intensity on the optical axis is 100%, an area having a luminous intensity of 80% or more is an area having an angle with respect to the optical axis of 20 degrees or less (that is, an angular area of 40 degrees centered on the optical axis). Inside). That is, each LED 19 has a directivity characteristic in which the ratio of the luminous intensity to the luminous intensity on the optical axis (relative luminous intensity) is 80% or more in a region where the angle with respect to the optical axis is 20 degrees or less.

ここで、仮に各ＬＥＤ１９及び照明カバー１７間の距離Ｙ（ｍｍ）が一定である場合、各ＬＥＤ１９間のピッチＸ（ｍｍ）を小さくしすぎると、互いに隣り合うＬＥＤ１９からの光が重なり合って、照明カバー１７での光斑（明暗）の程度が大きくなってしまう。逆に、各ＬＥＤ１９間のピッチＸ（ｍｍ）を大きくしすぎても、互いに隣り合うＬＥＤ１９からの光の範囲が独立してしまい、照明カバー１７での光斑（明暗）の程度が大きくなってしまう。従って、各ＬＥＤ１９間のピッチＸ（ｍｍ）が小さすぎても大きすぎても、意匠性が低下してしまう。   Here, if the distance Y (mm) between each LED 19 and the illumination cover 17 is constant, if the pitch X (mm) between the LEDs 19 is made too small, the light from the LEDs 19 adjacent to each other will overlap, resulting in illumination. The degree of light spots (brightness and darkness) on the cover 17 is increased. Conversely, even if the pitch X (mm) between the LEDs 19 is too large, the range of light from the LEDs 19 adjacent to each other becomes independent, and the degree of light spots (brightness and darkness) at the illumination cover 17 increases. . Therefore, if the pitch X (mm) between the LEDs 19 is too small or too large, the design properties are deteriorated.

そこで、各ＬＥＤ１９間のピッチＸ（ｍｍ）と、各ＬＥＤ１９及び照明カバー１７間の距離Ｙとを変化させながら、照明カバー１７における意匠性の評価（光の明暗の程度の評価）を行った。   Thus, the design property (evaluation of the degree of light brightness) of the illumination cover 17 was evaluated while changing the pitch X (mm) between the LEDs 19 and the distance Y between the LEDs 19 and the illumination cover 17.

図７は、図６の照明カバー１７での意匠性の評価、各ＬＥＤ１９間のピッチＸ（ｍｍ）、及び各ＬＥＤ１９及び照明カバー１７間の距離Ｙ（ｍｍ）のそれぞれの関係を示すグラフである。なお、図７では、各ＬＥＤ１９間のピッチＸ（ｍｍ）が３３．５（ｍｍ）である場合、及び６０（ｍｍ）である場合のそれぞれの場合について、意匠性の評価が示されている。また、図７において、意匠性の評価は、意匠性が良い場合に○、意匠性がやや劣る場合に△、意匠性が悪い場合に×で示されている。さらに、図７での意匠性の評価は、照明カバー１７の光の透過率が６０％であるときの評価である。   FIG. 7 is a graph showing the relationship between the evaluation of designability in the illumination cover 17 of FIG. 6, the pitch X (mm) between the LEDs 19, and the distance Y (mm) between the LEDs 19 and the illumination cover 17. . In addition, in FIG. 7, the evaluation of the designability is shown for each of the cases where the pitch X (mm) between the LEDs 19 is 33.5 (mm) and 60 (mm). In FIG. 7, the evaluation of the design property is indicated by “◯” when the design property is good, “Δ” when the design property is slightly inferior, and “x” when the design property is bad. Furthermore, the evaluation of the design property in FIG. 7 is an evaluation when the light transmittance of the illumination cover 17 is 60%.

図７に示すグラフから、照明カバー１７での意匠性は、各ＬＥＤ１９間のピッチＸ（ｍｍ）と、各ＬＥＤ１９及び照明カバー１７間の距離Ｙ（ｍｍ）との関係が以下の式（１）を満たすときに、良くなることが分かる。   From the graph shown in FIG. 7, the design of the lighting cover 17 is based on the relationship between the pitch X (mm) between the LEDs 19 and the distance Y (mm) between the LEDs 19 and the lighting cover 17 (1) It turns out that it gets better when meeting.

Ｙ≧０．９Ｘ＋９…（１）   Y ≧ 0.9X + 9 (1)

また、意匠性の評価は、照明カバー１７の光の透過率が４５％である場合、６０％である場合及び８０％である場合の３つの場合のそれぞれについて行った。この結果、各ＬＥＤ１９間のピッチＸ（ｍｍ）と各ＬＥＤ１９及び照明カバー１７間の距離Ｙ（ｍｍ）との関係が式（１）を満たす関係にあるときに、照明カバー１７の光の透過率が４５％及び６０％である場合は意匠性が良かったが、照明カバー１７の光の透過率が８０％である場合は各ＬＥＤ１９の姿が判別されるようになり意匠性が低下した。従って、照明カバー１７での意匠性が良くなるためには、照明カバー１７の光の透過率が少なくとも４５〜６０％の範囲内である必要がある。   In addition, the design property was evaluated for each of the three cases of the case where the light transmittance of the lighting cover 17 is 45%, the case of 60%, and the case of 80%. As a result, when the relationship between the pitch X (mm) between the LEDs 19 and the distance Y (mm) between the LEDs 19 and the illumination cover 17 satisfies the formula (1), the light transmittance of the illumination cover 17 is satisfied. Is 45% and 60%, the design is good, but when the light transmittance of the illumination cover 17 is 80%, the appearance of each LED 19 can be identified and the design is lowered. Therefore, in order to improve the design of the lighting cover 17, the light transmittance of the lighting cover 17 needs to be within a range of at least 45 to 60%.

さらに、照明カバー１７での意匠性は、ＬＥＤ１９の１つ当たりの光束値を５〜３０（ｌｍ（ルーメン））の範囲で変化させても、変わらずにそのまま維持された。従って、照明カバー１７での意匠性は、ＬＥＤ１９の１つ当たりの光束値に関係なく決まることが分かる。即ち、経年変化によってＬＥＤ１９の光度が落ちても、照明カバー１７での意匠性が維持され、照明カバー１７での光斑の程度の悪化が抑制されることが分かる。なお、ＬＥＤ１９については、１つ当たりの光束値が５（ルーメン）よりも低くなる前に交換されることが通常である。   Furthermore, the design of the lighting cover 17 was maintained as it was even when the luminous flux value per LED 19 was changed in the range of 5 to 30 (lm (lumen)). Therefore, it can be seen that the design of the lighting cover 17 is determined regardless of the luminous flux value per LED 19. That is, even if the luminous intensity of the LED 19 decreases due to secular change, it can be seen that the design property of the lighting cover 17 is maintained and the deterioration of the degree of light spots on the lighting cover 17 is suppressed. In addition, about LED19, it is normal to replace | exchange before the light beam value per one becomes lower than 5 (lumen).

この例では、各ＬＥＤ１９間のピッチＸ（ｍｍ）が３３．５（ｍｍ）とされ、各ＬＥＤ１９及び照明カバー１７間の距離Ｙ（ｍｍ）が４０（ｍｍ）とされている。即ち、この例では、各ＬＥＤ１９間のピッチＸ（ｍｍ）と、各ＬＥＤ１９及び照明カバー１７間の距離Ｙ（ｍｍ）との関係が式（１）を満たす関係となっている。   In this example, the pitch X (mm) between the LEDs 19 is 33.5 (mm), and the distance Y (mm) between the LEDs 19 and the illumination cover 17 is 40 (mm). That is, in this example, the relationship between the pitch X (mm) between the LEDs 19 and the distance Y (mm) between the LEDs 19 and the illumination cover 17 satisfies the formula (1).

なお、各ＬＥＤ１９と照明カバー１７との間にレンズを配置してＬＥＤからの光の拡散角を広げることにより、照明カバー１７を各ＬＥＤ１９に近づけて配置することも考えられるが、レンズによる光の回折等の影響により光斑が生じたり照度が低下したりするので、意匠性の向上には限界がある。   It is possible to arrange the illumination cover 17 close to each LED 19 by disposing a lens between each LED 19 and the illumination cover 17 to widen the diffusion angle of light from the LED. There is a limit to the improvement in design because light spots are generated or the illuminance is lowered due to the influence of diffraction or the like.

このようなエレベータのかご内照明装置では、光軸に対する角度が２０度以下である領域内で相対光度が８０％以上となる指向特性を各ＬＥＤ１９が持ち、各ＬＥＤ１９間のピッチＸ（ｍｍ）と、各ＬＥＤ１９及び照明カバー１７間の距離Ｙ（ｍｍ）との関係が、Ｙ≧０．９Ｘ＋９を満たす関係であるので、互いに隣り合うＬＥＤ１９について光度の高い範囲同士が重なることを避けることができ、照明カバー１７の位置での光度を均等に近づけることができる。従って、照明カバー１７において明暗が生じることを抑制することができ、照明カバー１７全体が均等に光っているかのような柔らかい印象を与える意匠に近づけることができる。これにより、照明装置８の意匠性の向上を図ることができる。また、各ＬＥＤ１９の指向特性が一般のＬＥＤの指向特性の範囲内に設定されているので、各ＬＥＤ１９のコストの低減化を図ることができる。   In such an elevator car illuminating device, each LED 19 has a directivity characteristic in which the relative luminous intensity is 80% or more in an area where the angle with respect to the optical axis is 20 degrees or less, and the pitch X (mm) between the LEDs 19 is Since the relationship with the distance Y (mm) between each LED 19 and the illumination cover 17 is a relationship satisfying Y ≧ 0.9X + 9, it is possible to avoid overlapping ranges of high light intensity for the LEDs 19 adjacent to each other, The luminous intensity at the position of the illumination cover 17 can be made close to each other. Therefore, it is possible to suppress the occurrence of light and darkness in the illumination cover 17, and it is possible to approach a design that gives a soft impression as if the entire illumination cover 17 shines evenly. Thereby, the design property of the illuminating device 8 can be improved. Moreover, since the directivity of each LED 19 is set within the range of directivity of a general LED, the cost of each LED 19 can be reduced.

また、ＬＥＤユニット１６は、放熱用の取付板１５を介して天蓋７に取り付けられているので、ＬＥＤユニット１６を天蓋７に取り付ける機能と、ＬＥＤユニット１６からの熱を放散する機能とを取付板１５で兼用させることができる。これにより、部品点数の低減化を図ることができる。また、複数のＬＥＤユニット１６をあらかじめ取り付けておいた共通の取付板１５を天蓋７に取り付けることにより、天蓋７へのＬＥＤユニット１６の取り付け作業も容易にすることができる。   Further, since the LED unit 16 is attached to the canopy 7 via the heat radiating attachment plate 15, the attachment plate has a function of attaching the LED unit 16 to the canopy 7 and a function of radiating heat from the LED unit 16. 15 can also be used. Thereby, the number of parts can be reduced. In addition, by attaching the common attachment plate 15 to which the plurality of LED units 16 have been attached in advance to the canopy 7, the attaching operation of the LED unit 16 to the canopy 7 can be facilitated.

なお、上記の例では、照明装置８がかご天井４のみに設けられているが、かご壁３及びかご床２の少なくともいずれかに照明装置８を設けてもよい。   In the above example, the lighting device 8 is provided only on the car ceiling 4, but the lighting device 8 may be provided on at least one of the car wall 3 and the car floor 2.

１ かご、４ かご天井、８ 照明装置、１５ 取付板、１６ ＬＥＤユニット（光源装置）、１７ 照明カバー、１９ ＬＥＤ。   1 car, 4 car ceiling, 8 lighting device, 15 mounting plate, 16 LED unit (light source device), 17 lighting cover, 19 LED.
