Description

本発明は、エレベータの乗りかご照明装置、および、エレベータに係り、特にＬＥＤランプから成る光源によりエレベータの乗りかご内を照明するエレベータの乗りかご照明装置に関するものである。 The present invention relates to an elevator car lighting device and, in particular, an elevator car lighting device that illuminates the inside of an elevator car with a light source including an LED lamp.

本技術分野の背景技術として、特許文献１がある。この特許文献１には、目地部材に向かう照射方向に目地部材の投影像を形成するＬＥＤランプの光を遮光体によって遮光して、ＬＥＤランプの照射方向に目地部材の投影像を生じ難くし、透光板の意匠性を向上させたものが記載されている。 Patent Document 1 is a background technique in this technical field. In Patent Document 1, the light of the LED lamp that forms the projected image of the joint member in the irradiation direction toward the joint member is blocked by a light-shielding body, so that the projected image of the joint member is less likely to be generated in the irradiation direction of the LED lamp. The ones with improved design of the translucent plate are described.

しかしながら、特許文献１では、天井に対してＬＥＤランプの光を遮光する遮光体を追加しており、部品点数の増加が生じている。 However, in Patent Document 1, a light-shielding body that blocks the light of the LED lamp is added to the ceiling, resulting in an increase in the number of parts.

そこで、本発明は、部品点数の増加を抑え、かつＬＥＤランプの照射方向に目地部材の投影像を生じ難くし、透光板の意匠性を向上させたエレベータ用乗りかご照明装置を提供する。 Therefore, the present invention provides an elevator car lighting device that suppresses an increase in the number of parts, makes it difficult to generate a projected image of a joint member in the irradiation direction of the LED lamp, and improves the design of the light transmitting plate.

上記課題を解決するために、本発明のエレベータの乗りかご照明装置は、複数の第一ＬＥＤランプを下方に向けて設けた第一ＬＥＤユニットと、複数の第二ＬＥＤランプを下方に向けて設けた第二ＬＥＤユニットと、該第一ＬＥＤユニットおよび該第二ＬＥＤユニットの下方を覆う透光板と、を具備し、前記透光板は、前記第一ＬＥＤユニットの下方に設けた第一透光プレートと、前記第二ＬＥＤユニットの下方に設けた第二透光プレートと、前記第一透光プレートと前記第二透光プレートの間に設けられ、前記第一透光プレートと前記第二透光プレートを支持する目地部材と、で構成され、前記第一ＬＥＤユニットには、前記第一ＬＥＤランプの発光が前記第二透光プレートに到達するのを防ぐ遮光壁が一体に設けられており、該遮光壁は、最も前記第二ＬＥＤユニット側に設けられた前記第一ＬＥＤランプまでの水平方向距離が、前記目地部材までの水平方向距離よりも短くなる位置に設けられている。 In order to solve the above problems, the elevator car lighting device of the present invention is provided with a first LED unit in which a plurality of first LED lamps are provided downward and a plurality of second LED lamps are provided in a downward direction. A second LED unit, a first LED unit, and a light-transmitting plate that covers the lower part of the second LED unit, and the light-transmitting plate is provided below the first LED unit. The light plate, the second light-transmitting plate provided below the second LED unit, and the first light-transmitting plate and the second light-transmitting plate provided between the first light-transmitting plate and the second light-transmitting plate. It is composed of a joint member that supports the translucent plate, and the first LED unit is integrally provided with a light-shielding wall that prevents the light emission of the first LED lamp from reaching the second translucent plate. The light-shielding wall is provided at a position where the horizontal distance to the first LED lamp provided on the second LED unit side is shorter than the horizontal distance to the joint member .

本発明によれば、目地部材に向かう照射方向に目地部材の投影像を形成するＬＥＤランプの光が、ＬＥＤランプを取り付けるプレート端部の曲げ立ち上がりにより遮光されるため、ＬＥＤランプの照射方向に目地部材の投影像が生じにくくなる。また、ＬＥＤランプの交換作業は、ＬＥＤランプ取り付けプレートを天井から取外すことで容易に作業が可能であり、ＬＥＤランプ取り付けプレートの端部の曲げ立ち上がりで遮光するため、部品点数の増加もない。 According to the present invention, the light of the LED lamp forming the projected image of the joint member in the irradiation direction toward the joint member is blocked by the bending rise of the end of the plate to which the LED lamp is attached, so that the joint is shielded in the irradiation direction of the LED lamp. The projected image of the member is less likely to occur. Further, the replacement work of the LED lamp can be easily performed by removing the LED lamp mounting plate from the ceiling, and since the light is shielded by the bending rise of the end portion of the LED lamp mounting plate, the number of parts does not increase.

以下、本発明の一実施例を図面に基づいて説明する。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

図１は本実施例のエレベータの乗りかごの内部を示す斜視図である。ここに示すように、エレベータの乗りかご１は、床２と、床２に立設される側板３と、出入口となるドア４と、頂上部を形成する天井５と、天井５に設置される照明装置６を有している。なお、図１では手前側の側板３の図示を省略している。 FIG. 1 is a perspective view showing the inside of the car of the elevator of this embodiment. As shown here, the elevator car 1 is installed on the floor 2, the side plate 3 erected on the floor 2, the door 4 serving as an entrance / exit, the ceiling 5 forming the top, and the ceiling 5. It has a lighting device 6. In FIG. 1, the side plate 3 on the front side is not shown.

照明装置６の下方には透光板７が備えられ、また、天井５の四辺にはフレーム８があり、これで透光板７を支える構成としている。 A translucent plate 7 is provided below the lighting device 6, and frames 8 are provided on the four sides of the ceiling 5 to support the translucent plate 7.

図２、図３は、照明装置６を下方から見た平面図、その断面図である。 2 and 3 are a plan view and a cross-sectional view of the lighting device 6 as viewed from below.

照明装置６は、床２に対向するように天井５に設けられたものであり、乗りかご１の前後方向に二つのＬＥＤユニット１２を並べて配置している。ＬＥＤユニット１２を覆う透光板７は、乳白色のアクリル樹脂からなる透光プレート７ａと、透光プレート７ａの端部を囲む目地部材７ｂから構成されており、各ＬＥＤユニット１２に対応する透光プレート７ａの間に目地部材７ｂを配置している。なお、図２では、乗りかご１の前後方向に矩形のＬＥＤユニット１２、透光プレート７ａを並べたが、これらの形状、数は、乗りかご１の天井のデザインなどに応じて、任意に設定して良い。 The lighting device 6 is provided on the ceiling 5 so as to face the floor 2, and two LED units 12 are arranged side by side in the front-rear direction of the car 1. The light-transmitting plate 7 that covers the LED unit 12 is composed of a light-transmitting plate 7a made of milky white acrylic resin and a joint member 7b that surrounds the end of the light-transmitting plate 7a. The joint member 7b is arranged between the plates 7a. In FIG. 2, rectangular LED units 12 and translucent plates 7a are arranged in the front-rear direction of the car 1, but the shapes and numbers thereof can be arbitrarily set according to the design of the ceiling of the car 1. You can do it.

図３は図２のＡ−Ａでの照明装置６の断面図である。ここに示すように、天井５には二つのＬＥＤユニット１２が左右に並べてネジなどで取り付けられており、また、天井５の四辺に設けたフレーム８には透光プレート７ａと目地部材７ｂからなる透光板７が載置されている。 FIG. 3 is a cross-sectional view of the lighting device 6 in AA of FIG. As shown here, two LED units 12 are attached to the ceiling 5 side by side with screws or the like, and the frame 8 provided on the four sides of the ceiling 5 is composed of a translucent plate 7a and a joint member 7b. A translucent plate 7 is placed.

ＬＥＤユニット１２は、下方を向いたＬＥＤランプ９と、ＬＥＤランプ９を取り付けたＬＥＤ基板１０と、ＬＥＤ基板１０を取り付けたプレート１１から構成されている。なお、ＬＥＤ基板１０には後述する電線１３を介して外部電源から電力が供給される。 The LED unit 12 is composed of an LED lamp 9 facing downward, an LED substrate 10 to which the LED lamp 9 is attached, and a plate 11 to which the LED substrate 10 is attached. Electric power is supplied to the LED substrate 10 from an external power source via an electric wire 13 described later.

本実施例では、目地部材７ｂの近傍に明るさ斑が生じることを防ぐため、プレート１１の端部に遮光壁１１ａを設けている。この遮光壁１１ａは、プレート１１の端部を曲げ加工して、他方のＬＥＤユニット側に設けられたＬＥＤランプと目地部材の上端部を結ぶ直線よりも下方まで伸ばしたものであり、プレート１１と一体化することにより比較的小さく構成することができる。 In this embodiment, a light-shielding wall 11a is provided at the end of the plate 11 in order to prevent brightness spots from occurring in the vicinity of the joint member 7b. The light-shielding wall 11a is formed by bending the end portion of the plate 11 and extending it below the straight line connecting the LED lamp provided on the other LED unit side and the upper end portion of the joint member. By integrating, it can be configured relatively small.

次に、図３を用いて、左側のＬＥＤユニット１２の右列のＬＥＤランプ９のみを点灯した状態を例に、遮光壁１１ａが明るさ斑を改善する理由を説明する。 Next, with reference to FIG. 3, the reason why the light-shielding wall 11a improves the brightness unevenness will be described by taking as an example a state in which only the LED lamp 9 in the right column of the left LED unit 12 is lit.

遮光壁１１ａを設けない場合、左側のＬＥＤユニット１２の右列のＬＥＤランプ９を点灯すると、矢印３１と矢印３４で挟まれる領域、すなわち、左側の透光プレート７ａのほぼ全域（矢印３１と目地部材７ｂで挟まれる領域）、目地部材７ｂの左面と上面、および、右側の透光プレート７ａの一部（矢印３３と矢印３４で挟まれる領域）に光が照射される。一方、目地部材７ｂの影となる、目地部材７ｂの右面と、右側の透光プレート７ａの目地部材７ｂ近傍（目地部材７ｂと矢印３３で挟まれる領域）には光が届かない。 When the light-shielding wall 11a is not provided, when the LED lamp 9 in the right column of the left LED unit 12 is turned on, the area sandwiched between the arrows 31 and 34, that is, almost the entire area of the light-transmitting plate 7a on the left side (arrow 31 and joints). The area sandwiched between the members 7b), the left surface and the upper surface of the joint member 7b, and a part of the translucent plate 7a on the right side (the area sandwiched between the arrows 33 and 34) are irradiated with light. On the other hand, the light does not reach the right surface of the joint member 7b, which is the shadow of the joint member 7b, and the vicinity of the joint member 7b of the translucent plate 7a on the right side (the region sandwiched between the joint member 7b and the arrow 33).

すなわち、遮光壁１１ａを設けない場合、左側のＬＥＤユニット１２を点灯すると、右側の透光プレート７ａの目地部材７ｂ近傍には暗い領域（目地部材７ｂと矢印３３に挟まれる領域）と明るい領域（矢印３３と矢印３４に挟まれる領域）からなる明るさ斑が発生する。同様の理由で、右側のＬＥＤユニット１２を点灯すると、左側の透光プレート７ａの目地部材７ｂ近傍でも明るさ斑が発生する。このため、左右のＬＥＤユニット１２をともに点灯する実使用時においても、目地部材７ｂの両側に明るさ斑が発生してしまう。 That is, when the light-shielding wall 11a is not provided, when the LED unit 12 on the left side is turned on, a dark area (a region sandwiched between the joint member 7b and the arrow 33) and a bright area (a region sandwiched between the joint member 7b and the arrow 33) and a bright area (a region sandwiched between the joint member 7b and the arrow 33) and a bright region (a region sandwiched between the joint member 7b and the arrow 33) and a bright region (a region sandwiched between the joint member 7b and the arrow 33) are formed in the vicinity of the joint member 7b of the light transmitting plate 7a on the right side. Brightness spots (regions sandwiched between the arrows 33 and the arrows 34) are generated. For the same reason, when the LED unit 12 on the right side is turned on, brightness spots occur even in the vicinity of the joint member 7b of the translucent plate 7a on the left side. Therefore, even in actual use in which both the left and right LED units 12 are turned on, brightness spots occur on both sides of the joint member 7b.

これに対し、遮光壁１１ａを設けた場合、左側のＬＥＤユニット１２の右列のＬＥＤランプ９からは矢印３１と矢印３２で挟まれる領域（左側の透光プレート７ａのほぼ全域、目地部材７ｂの左面）に光が照射される。一方、遮光壁１１ａの影となる、目地部材７ｂの上面と右面、および、右側の透光プレート７ａには光が届かない。 On the other hand, when the light-shielding wall 11a is provided, the area sandwiched between the arrows 31 and 32 from the LED lamp 9 in the right column of the left LED unit 12 (almost the entire area of the light-transmitting plate 7a on the left side, the joint member 7b). The left side) is illuminated with light. On the other hand, the light does not reach the upper surface and the right surface of the joint member 7b and the light transmitting plate 7a on the right side, which are shadows of the light-shielding wall 11a.

すなわち、遮光壁１１ａを設けた場合、左側のＬＥＤユニット１２を点灯しても右側の透光プレート７ａには光が照射されないため、明るさ斑は発生しない。同様の理由で、右側のＬＥＤユニット１２が点灯しても、左側の透光プレート７ａでも明るさ斑は発生しない。このため、左右のＬＥＤユニット１２をともに点灯する実使用時においても、目地部材７ｂの両側に明るさ斑は発生しない。 That is, when the light-shielding wall 11a is provided, even if the LED unit 12 on the left side is turned on, the light-transmitting plate 7a on the right side is not irradiated with light, so that no brightness unevenness occurs. For the same reason, even if the LED unit 12 on the right side is turned on, the brightness spot does not occur on the translucent plate 7a on the left side. Therefore, even in actual use in which both the left and right LED units 12 are turned on, brightness spots do not occur on both sides of the joint member 7b.

図４は、本実施例のＬＥＤユニット１２の詳細を示す。ＬＥＤユニット１２には前述したようにＬＥＤランプ９を実装したＬＥＤ基板１０と、プレート１１があり、さらにＬＥＤ基板１０に通電するための電線１３から構成される。この電線１３は、例えば天井５の外側に設置される照明電源（図示なし）まで敷設する必要があるが、ＬＥＤ基板１０の周囲に電線１３を敷設すると、電線のたるみなどにより透光板７に配線影が生じる恐れがある。本実施例では、プレート１１の遮光壁１１ａの外側底面に、フックや貫通穴からなる配線保持部１１ｂを設けており、これを用いて、電線１３をプレート１１の外側にたるみなく敷設することが可能となる。これにより、配線影が生じる恐れもない。 FIG. 4 shows the details of the LED unit 12 of this embodiment. As described above, the LED unit 12 includes an LED substrate 10 on which the LED lamp 9 is mounted, a plate 11, and an electric wire 13 for energizing the LED substrate 10. For example, the electric wire 13 needs to be laid up to a lighting power source (not shown) installed outside the ceiling 5, but when the electric wire 13 is laid around the LED substrate 10, the slack of the electric wire causes the light transmitting plate 7 to lay. There is a risk of wiring shadows. In this embodiment, a wiring holding portion 11b composed of a hook or a through hole is provided on the outer bottom surface of the light-shielding wall 11a of the plate 11, and the electric wire 13 can be laid on the outside of the plate 11 without slack. It will be possible. As a result, there is no possibility that wiring shadows will occur.

以上で説明した、本実施例の構成によれば、プレート１１と一体に構成した簡易な遮光壁１１ａで、目地部材７ｂを跨ぐ光を遮光することができるため、透光プレート７ａの目地部材７ｂ近傍に発生する明るさ斑を解消することができ、明るさ斑が原因となる照明装置６の意匠性の劣化を防止できる。 According to the configuration of the present embodiment described above, the simple light-shielding wall 11a integrally formed with the plate 11 can block the light straddling the joint member 7b, so that the joint member 7b of the translucent plate 7a can be blocked. Brightness spots generated in the vicinity can be eliminated, and deterioration of the design of the lighting device 6 caused by the brightness spots can be prevented.

また、本実施例では、遮光壁１１ａをＬＥＤランプ９に近接配置しているので、目地部材７ｂを跨ぐ光を全て遮光するために必要とされる高さを低くすることができる。すなわち、遮光壁１１ａを形成するために必要とされるプレート１１の大きさを抑制することができコストアップを抑制することができる。さらに、ＬＥＤランプ９に近接配置した遮光壁１１ａは、ＬＥＤランプ９のガード部材としても機能し、透光板７の取付け、取外し時に、透光板７がＬＥＤランプ９に接触するのを防止することができる。 Further, in the present embodiment, since the light-shielding wall 11a is arranged close to the LED lamp 9, the height required to block all the light straddling the joint member 7b can be lowered. That is, the size of the plate 11 required to form the light-shielding wall 11a can be suppressed, and the cost increase can be suppressed. Further, the light-shielding wall 11a arranged close to the LED lamp 9 also functions as a guard member of the LED lamp 9 and prevents the light-transmitting plate 7 from coming into contact with the LED lamp 9 when the light-transmitting plate 7 is attached or detached. be able to.

なお、本実施例では、部品点数の増加やコストアップを抑制するため、プレート１１を曲げ加工することで遮光壁１１ａを形成したが、両者を別々の部品として用意し、ネジや接着剤で一体化する構成としても良い。 In this embodiment, the light-shielding wall 11a is formed by bending the plate 11 in order to suppress an increase in the number of parts and an increase in cost. However, both are prepared as separate parts and integrated with screws or an adhesive. It may be configured to be changed.
