本発明は、エスカレータや動く歩道等の乗客コンベアに備えられ、乗降部付近を照明するLEDを有する乗客コンベアの照明装置に関する。  The present invention relates to a lighting device for a passenger conveyor that is provided on a passenger conveyor such as an escalator or a moving sidewalk, and that has an LED that illuminates the vicinity of a boarding / alighting section.

従来、乗客コンベアでは、乗客が乗降する乗降部の近傍の、踏面と乗降部のそれぞれの両脇に位置するスカートに、開口部を設け、この開口部から乗客の注意を喚起する照明を照光するようにした照明装置が知られている。  Conventionally, in a passenger conveyor, an opening is provided in a skirt located on both sides of a tread surface and a boarding / alighting part in the vicinity of a boarding / alighting part where passengers get on / off, and illumination for illuminating the passengers' attention is emitted from this opening. Such a lighting device is known.

この照明装置は、蛍光灯から成るものであった。しかし、蛍光灯は電極フィラメントに高圧の交流を印加し、多量の熱電子を放出することによって光を発するようになっているため、消費電力が比較的大きくなる。また、電極フィラメントの消耗により蛍光灯が点灯しなくなるため、寿命が比較的短い。これに伴って、蛍光灯の交換を頻繁に行なうことが必要になり、このような交換作業は、作業員の負担を招いていた。さらに蛍光灯は、内部に水銀やアルゴンガスが封入されており、蛍光灯の寿命等により蛍光灯を廃棄する際、破砕した蛍光灯のガラス片には水銀が付着している。このため、それらのガラス片を産業廃棄物としてそのまま地中に埋めると、土壌を汚染してしまうことになる。  This illuminating device consisted of a fluorescent lamp. However, since the fluorescent lamp emits light by applying a high-voltage alternating current to the electrode filament and emitting a large amount of thermoelectrons, the power consumption becomes relatively large. In addition, the life of the fluorescent lamp is relatively short because the fluorescent lamp is not lit due to consumption of the electrode filament. Along with this, it is necessary to frequently exchange fluorescent lamps, and such exchange work has caused a burden on workers. Further, the fluorescent lamp is filled with mercury or argon gas, and when the fluorescent lamp is discarded due to the life of the fluorescent lamp or the like, mercury adheres to the glass piece of the crushed fluorescent lamp. For this reason, if those glass pieces are buried in the ground as industrial waste, the soil is contaminated.

このような問題を解決しようとして、特許文献1に示される乗客コンベアの照明装置が提案されている。この従来の照明装置は、通電によりそれぞれ発光する複数個のLED体を備えたLED照明灯であり、このLED照明灯は、細長の剛性材から成り、複数個のLED体が上面側の長手方向に沿って所定間隔で配設されるプリント基板と、このプリント基板を収納し、透光性及び保形性を有する細長管と、プリント基板の下面側に配設される全波整流ダイオード、及び複数個の電流制限抵抗を含む電気部品と、細長管の両端に取り付けられ、プリント基板を細長管内に固定する絶縁材から成る一対のブッシングと、これらのブッシングの外周のそれぞれに装着される一対の口金具と、これらの口金具にそれぞれ設けられる一対の電極ピンと、これらの電極ピンとプリント基板との電気的接続を行なう接続体などを備えた構成になっている。
特開2002−140901公報
In order to solve such a problem, an illumination device for a passenger conveyor shown inPatent Document 1 has been proposed. This conventional illuminating device is an LED illuminating lamp provided with a plurality of LED bodies that emit light when energized.

A printed circuit board disposed at predetermined intervals along the line, an elongated tube that houses the printed circuit board and has translucency and shape retention, a full-wave rectifier diode disposed on the lower surface side of the printed circuit board, and A pair of electric parts including a plurality of current limiting resistors, a pair of bushings made of an insulating material that is attached to both ends of the elongated tube and fixes the printed circuit board in the elongated tube, and a pair of outer peripherals of these bushings. It has a configuration including a fitting, a pair of electrode pins provided on each of the fittings, and a connection body that electrically connects these electrode pins and the printed board.

FIG. 3 is a view taken in the direction of the arrow Y in FIG. It is the figure drawn by adding a skirt to.

本発明に係る照明装置の第1実施形態は、これらの図2,3に示すように、スカート4の反踏面側の開口部5位置よりも上方の位置に配置され、例えば水平面に対して傾斜した下部延設部7Aを有し、放熱性の高い素材から成るL字形のプレート7と、このプレート7の下部延設部7Aの下側に当接するように固定したLED照明部8と、プレート7の下部延設部7Aの下側に固定され、LED照明部8を光らせる駆動部9とを備えている。また、LED照明部8と駆動部9を接続する第1配線コード10と、電源回路部11と駆動部9を接続する第2配線コード12とを備えている。図3に示すように、LED照明部8と駆動部9は、水平面に対して傾斜した下部延設部7Aの傾斜上方側にLED照明部8を、下方側に駆動部9を固定してある。As shown in FIGS. 2 and 3, the first embodiment of the lighting device according to the present invention is disposed at a position above the position of theopening 5 on the side opposite to the tread of theskirt 4, and is inclined with respect to the horizontal plane, for example. An L-shaped plate 7 made of a material with high heat dissipation, anLED illumination unit 8 fixed so as to contact the lower side of the lower extension 7A of theplate 7, and aplate 7, and adrive unit 9 that is fixed to the lower side of the lower extendingportion 7 </ b> A and that illuminates theLED illumination unit 8. Moreover, the1st wiring cord 10 which connects theLED illumination part 8 and thedrive part 9 and the2nd wiring cord 12 which connects the powersupply circuit part 11 and thedrive part 9 are provided.As shown in FIG. 3, theLED illumination unit 8 and thedrive unit 9 have theLED illumination unit 8 fixed to the upper side of the lower extension 7A inclined with respect to the horizontal plane and thedrive unit 9 fixed to the lower side. .

開口部5は、LED照明部8から発せられた光を乗降部3の方向に不足なく通し、乗客の足元を照らすことができる。また、遮蔽板6は、開口部5を完全に覆うように配置され、乗降部3の方向から塵埃等の異物が侵入してLED照明部8や駆動部9に付着することを防ぐとともに、半透明から成る材質で形成されていることによりLED照明部8から発せられた光を、乗降部3の方向に不足なく透過させることができる。  Theopening part 5 can pass the light emitted from theLED illumination part 8 in the direction of the getting-on / offpart 3 without shortage, and can illuminate the feet of the passenger. In addition, theshielding plate 6 is disposed so as to completely cover theopening 5, and prevents foreign matters such as dust from entering from the direction of the getting-on / offunit 3 and adhering to theLED illumination unit 8 and thedrive unit 9. By being formed of a transparent material, the light emitted from theLED illumination unit 8 can be transmitted in the direction of the getting-on / offunit 3 without shortage.

プレート7は、LED照明部8の上側を完全に覆い、上方の隙間等から浸入した雨水等、及び塵埃等の異物がLED照明部8に付着することを阻止する。また、L字形のプレート7の折り曲げ角度θ1は、90°よりも僅かに大きい鈍角となっている。  Theplate 7 completely covers the upper side of theLED illuminating unit 8, and prevents foreign matter such as rainwater or the like entering from the upper gap or the like from adhering to the LEDilluminating unit 8. Further, the bending angle θ1 of the L-shaped plate 7 is an obtuse angle slightly larger than 90 °.

なお、LED照明部8の放熱は、LED照明部8の長期間にわたる高輝度の維持と長寿命化にあたって極めて重要な役割を果たしている。一般に、LEDは他のどのような発光デバイスよりも発熱する上、LED自身が熱に弱いデバイスであるため、積極的な放熱対策を行なわない状態での使用では、輝度の減少や4万時間といわれる寿命の短命化や、破損を招くことになる。LEDデバイスからの赤外線輻射による空気中への直接の放熱はほとんどなく、LEDが直接接触している基板と、基板が接触している部材への伝熱に依存する。したがって、本実施形態に備えられるプレート7の高い放熱性は、LED照明部8の長期間にわたる高輝度の維持と長寿命化を実現させるものである。  The heat radiation of theLED illumination unit 8 plays an extremely important role in maintaining high brightness and extending the life of theLED illumination unit 8 over a long period of time. In general, an LED generates heat more than any other light-emitting device, and the LED itself is a device that is weak against heat. This will shorten the service life and cause damage. There is almost no direct heat release to the air by infrared radiation from the LED device, and it depends on the heat transfer to the substrate in direct contact with the LED and the member in contact with the substrate. Therefore, the high heat dissipation of theplate 7 provided in the present embodiment realizes the maintenance of high brightness and long life of theLED illumination unit 8 over a long period of time.

このように構成した第1実施形態によれば、上部の隙間等から浸入した雨水等がLED照明部8に接触しないように、これらの雨水等を水平面に対して傾斜したプレート7の下部延設部7Aによって排出させることができる。また、プレート7の下部延設部7Aとの当接を介して、LED照明部8で生じた熱をプレート7によって放熱させることができる。すなわち、LED照明部8を備えたものにあって、優れた防水性と放熱性を確保することができ、これによりLED照明部8の長期間にわたる高輝度の維持と長寿命化を実現させることができる。これに伴って、LED照明部8の交換の頻度を少なくすることができ、この交換作業を行なう保守員の労力を軽減させることができる。  According to the first embodiment configured as described above, the lower portion of theplate 7 that is inclined with respect to the horizontal plane is arranged so that rainwater or the like that has entered from the upper gap or the like does not contact theLED illumination unit 8. It can be discharged by the part 7A. Further, the heat generated in theLED illumination unit 8 can be dissipated by theplate 7 through contact with the lower extendingportion 7 </ b> A of theplate 7. That is, in the thing equipped with theLED illumination part 8, the outstanding waterproofness and heat dissipation can be ensured, and, thereby, the high-intensity maintenance and long life of theLED illumination part 8 are implement | achieved. Can do. Accordingly, the replacement frequency of theLED illumination unit 8 can be reduced, and the labor of maintenance personnel performing this replacement work can be reduced.

また、プレート7は、水平面に対して傾斜した下部延設部7Aを有する簡単な形状であることから、実用的であるとともに、製作コストを抑えることに貢献する。  Moreover, since theplate 7 has a simple shape having the lower extending portion 7A inclined with respect to the horizontal plane, theplate 7 is practical and contributes to reducing the manufacturing cost.

図4は本発明の第2実施形態を示す図で、第1実施形態を示す図3に対応させて描いた図である。  FIG. 4 is a view showing a second embodiment of the present invention, and is a drawing corresponding to FIG. 3 showing the first embodiment.

この図4に示す第2実施形態は、前述した第1実施形態の構成に加えて、LED照明部8の反開口部5側を形成する背面に、放熱板、すなわち例えば平板から成る別のプレート13を当接するように設けた構成にしてある。  In addition to the configuration of the first embodiment described above, the second embodiment shown in FIG. 4 is a heat sink, that is, another plate made of, for example, a flat plate on the back surface forming the side opposite to theopening 5 of theLED illumination unit 8. 13 is provided so as to abut.

プレート13は、プレート7と同様に放熱性の高い素材から成り、LED照明部8が発した熱が伝導されて効率的な放熱を可能とするものである。前述のように、LED照明部8は、このLED照明部8に接する部材への伝熱に依存するため、この第2実施形態によれば、放熱性の高いプレート7と別のプレート13の双方における放熱によって、第1実施形態におけるよりもさらに優れた放熱性を確保することができる。なお、別のプレート13は簡単な形状であることから、実用的であるとともに、製作コストを抑えることに貢献する。  The plate 13 is made of a material having a high heat dissipation property like theplate 7, and heat emitted from theLED illumination unit 8 is conducted to enable efficient heat dissipation. As described above, since theLED illumination unit 8 depends on heat transfer to the member in contact with theLED illumination unit 8, according to the second embodiment, both theplate 7 having a high heat dissipation property and the other plate 13 are used. Due to the heat dissipation in, better heat dissipation than in the first embodiment can be ensured. In addition, since another plate 13 is a simple shape, while being practical, it contributes to holding down manufacturing cost.

図5は本発明の第3実施形態を示す図で、第1実施形態を示す図3に対応させて描いた図である。  FIG. 5 is a diagram showing a third embodiment of the present invention, and is a diagram corresponding to FIG. 3 showing the first embodiment.

この図5に示す第3実施形態は、前述した第1実施形態の構成に加えて、LED照明部8と駆動部9とが固定されるプレート7の部分、すなわち下部延設部7Aに複数の穴、例えば円穴14を設け、プレート7の上方位置に、例えば水平面に対して傾斜した下部延設部15Aを有し、放熱性の高い素材から成るL字形の別のプレート15を備えた構成にしてある。この別のプレート15の下部延設部15Aは、プレート7の上側の全体を覆うことが可能な形状寸法に設定されている。  In addition to the configuration of the first embodiment described above, the third embodiment shown in FIG. 5 includes a plurality of portions on theplate 7 where theLED illumination unit 8 and thedrive unit 9 are fixed, that is, the lower extension 7A. A structure in which a hole, for example, acircular hole 14 is provided, a lower extending portion 15A inclined with respect to a horizontal plane, for example, is provided at an upper position of theplate 7, and another L-shapedplate 15 made of a material with high heat dissipation is provided. It is. The lower extendingportion 15 </ b> A of theother plate 15 is set to a shape and dimension that can cover the entire upper side of theplate 7.

このように構成した第3実施形態によれば、プレート7は、複数設けられた円穴14を介して、さらに効率の良い放熱を実現できる。しかしながら、上方から雨水等が侵入した場合、その雨水等が円穴14から入り込み、LED照明部8や駆動部9に接触する虞がある。このことを考慮して、L字形の別のプレート15の折り曲げ角度θ2は、90°よりも僅かに大きい鈍角に形成し、これによって下部延設部15Aを水平面に対して傾斜させ、下部延設部15Aに付着した雨水等を、この下部延設部15Aを介して排出させるようにしてある。この第3実施形態にあっても、高い放熱性と防水性を確保することができる。また、別のプレート15も前述したプレート7と同様に、水平面に対して傾斜した下部延設部15Aを有する簡単な形状であることから、実用的であるとともに、製作コストを抑えることに貢献する。  According to 3rd Embodiment comprised in this way, theplate 7 can implement | achieve more efficient heat dissipation via thecircular hole 14 provided with two or more. However, when rainwater or the like enters from above, the rainwater or the like may enter from thecircular hole 14 and come into contact with theLED illumination unit 8 or thedrive unit 9. In consideration of this, the bending angle θ2 of the other L-shapedplate 15 is formed to be an obtuse angle slightly larger than 90 °, whereby the lower extending portion 15A is inclined with respect to the horizontal plane, and the lower extending portion is provided. Rain water or the like adhering to the portion 15A is discharged through the lower extending portion 15A. Even in the third embodiment, high heat dissipation and waterproofing can be ensured. Further, theother plate 15 has a simple shape having the lower extending portion 15A inclined with respect to the horizontal plane, like theplate 7 described above, and thus is practical and contributes to reducing the manufacturing cost. .
