Description

【0001】
【発明の属する技術分野】
本発明はエレベータ乗場やかご内に設置される表示装置の改良に関するものである。
【0002】
【従来の技術】
図4に示すように、エレベータの乗場にはかご呼び登録用の乗場ボタン1、かごの位置を表示するインジケータ2、かごの到着予報、走行方向等を表示するホールランタン3などが配置されている。4は三方枠、5は乗場ドアである。また図示省略するが、かご室内にもかご操作盤やかご位置表示灯などが設置されており、これらの表示装置の光源としては白熱灯が使用される場合が多い。
【0003】
例えば、ホールランタン3の場合、その断面は図5に示すようになっている。図において、11はフェースプレート、12はボックスであり、乗場壁6に空けられた穴に埋め込まれている。13a,13bはフェースプレート11に固定された上下の表示透光体であり矢印などが表示されている。14a,14bは表示透光体13a,13bの裏面に取り付けられたカラーフィルタで、例えば14aは緑色、14bは赤色である。15a,15bは白熱ランプ、16は遮光壁である。17は乗場壁6の昇降路側に固定されたプリント板ボックス、18はボックス12側とボックス17側、更に図示省略した制御盤を結ぶ配線である。
【0004】
【発明が解決しようとする課題】
この従来例では、光源として白熱ランプ15a,15bを使用しているため、ランプの玉切れによるランプ交換が必要で、またランプの光漏れ対策として遮光壁16が必要であるとともに、表示透光体13a,13bと白熱ランプ15a,15bとの距離が短いときには光むらが発生するという問題がある。更にボックス12を埋め込むために乗場壁6に大きな穴を空けなければならないという問題がある。更にまた、群管理制御でマイコン等を組込んだプリント板を使用する場合、白熱ランプの発熱の影響を避けるため、プリント板をプリント板ボックス17に別置きしなければならないという問題もある。
【0005】
そこで、白熱ランプに代えてLEDを使用することにより、ランプ交換作業をなくするとともに、発熱を抑え、光源の小型化を実現する構成も増えている。
しかしながら、白熱ランプをLEDに置き換えただけの構成では、遮光壁は必要であり、またボックス12はある程度の厚さが必要になってくるため、乗場壁6にはボックス12用の穴を空ける必要があった。
【0006】
【課題を解決するための手段】
本発明は、平板状の導光板の一側面又は複数の側面にLEDからなる光源を設けた構成の面発光体を使用することにより、従来技術の課題を解決するものである。
【0007】
【発明の実施の形態】
本発明の実施の形態を図1,図2により説明する。図1は図5に相当する図、図2(a),(b)は面発光体を示す図である。
図において、20は本実施形態のホールランタン、21は周囲が湾曲したフェースプレート、22は底板、23a,23bは面発光体、24はプリント板、25はホールランタン20を乗場壁6に固定するアンカーボルトであり、図5と同一符号は同一のものを示している。
【0008】
30は透明アクリルの透光体からなる導光板、31はLED基板に発光色の異なるLED32,33が交互に配置された光源で、例えば32は発光色が黄色のLED、33は同じく赤色のLEDである。導光板30の対向する二側面には光源31が配置され、表面には表示透光体13a又は13bが配置されている。また、光源31が配置された側面及び表面以外の面は遮光面になっている。更に背面30rには導光印刷が施され、その外側及び側面の遮光面には反射シート35が設けられており、面発光体23a,23bの表面全体が均一に光るように構成している。34は導光板30の表面に設けた透光性の拡散シートである。
【0009】
本実施の形態はこのような構成であるから、白熱ランプに比べ光源からの発熱を抑えられるので、プリント板24をホールランタン20の本体内に組込むことができるため、プリント板ボックス17を省略することができる。
また、白熱ランプや白熱ランプの代わりにLEDを配置しただけの従来技術に比べ、ホールランタン20をより薄型化することができる。そのため、図1のようにホールランタン20を乗場壁6の表面に取り付ける、いわゆる壁掛式にすることが可能になり、従来必要であった乗場壁6へのボックス用の穴を省略することができる。
【0010】
更に、面発光体23a,23bの側面は光源31又は遮光面となっており、光漏れがほとんどないため、従来必要であった遮光壁16が不要となる。また面発光体23a,23bは光むらがほとんどないため、表示透光体13a,13bを丸型など自由な形状にすることができる。
【0011】
また、2色のLEDを使用しているため、例えば、その乗場にかごが割り当てられたときには面発光体23a(又は23b)を黄色に発光させ、かごの到着時には赤色に点滅発光させるなど、エレベータの運転状況に応じて表示を変えることができる。更に面発光体自体が有色発光するため、カラーフィルタを省略することができる。また逆にLEDを白色としてカラーフィルタを使用するなど、LEDとカラーフィルタを組み合わせて使用することもできる。
更にまた、導光板30の表面の拡散シート34に矢印などの印刷を施すことにより、表示透光体13a,13bを省略又は単なる透明カバーに変更することも可能である。
【0012】
図3は本発明の他の実施の形態を示す図で、図2に相当する図である。この実施の形態の特徴は、導光板40を複数の小導光板41に分割していることである。そして各小導光板41の対向する両側面にはそれぞれLED43が位置するように光源42が設けられている。また、導光板40の表面の拡散シート34には矢印の印刷が施されている。
【0013】
この実施の形態においては、各小導光板41を独立に点灯制御できるため、例えば、エレベータの運行状態に合わせて下方の小導光板41から順に点灯させていくことにより、乗場の待客によりわかりやすい表示を行うことができる。
図3では、小導光板41の両側面に1個づつのLED43を配置しているが、発光色の異なる複数のLEDを各側面に配置することもできる。
【0014】
以上の各説明において、導光板の対向する二側面にLEDからなる光源を設けているが、光源から離れるほど光の反射が大きくなる導光印刷を施すことにより、導光板の一側面のみに光源を設けるだけでも光むらを防止することができる。
【0015】
前記の各実施の形態では壁掛式のホールランタンについて説明したが、ボックスを有するタイプのホールランタンに適用することもできる。また、ホールランタンに限らず、乗場インジケータ2やかご内表示装置、乗場ボタン1の応答灯やかご内操作盤の応答灯等の表示灯に応用することも可能である。
【0016】
【発明の効果】
以上説明したように、本発明によれば、表示装置を薄型にできるため、壁掛式の表示装置を実現することができる。また適度な導光印刷を施すことにより光のむらをなくし、複数色のLEDの使用や導光板の分割により、各種の表示を行うことができる。

BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a display device installed in an elevator hall or a car.
[0002]
[Prior art]
As shown in FIG. 4, a hall button 1 for car call registration, an indicator 2 for displaying the position of the car, a hall lantern 3 for displaying the arrival forecast of the car, the traveling direction, and the like are arranged at the elevator hall. . 4 is a three-way frame, and 5 is a landing door. Although not shown in the figure, a car operation panel, a car position indicator lamp, and the like are also installed in the car room, and incandescent lamps are often used as the light source of these display devices.
[0003]
For example, in the case of hole lantern 3, the cross section is as shown in FIG. In the figure, reference numeral 11 denotes a face plate, and 12 denotes a box, which is embedded in a hole formed in the landing wall 6. Reference numerals 13a and 13b are upper and lower display translucent bodies fixed to the face plate 11, and arrows and the like are displayed thereon. Reference numerals 14a and 14b denote color filters attached to the back surfaces of the display translucent bodies 13a and 13b. For example, 14a is green and 14b is red. 15a and 15b are incandescent lamps, and 16 is a light shielding wall. Reference numeral 17 denotes a printed board box fixed to the hoistway side of the landing wall 6, and 18 denotes a wiring connecting the box 12 side and the box 17 side and a control panel (not shown).
[0004]
[Problems to be solved by the invention]
In this conventional example, since the incandescent lamps 15a and 15b are used as the light source, it is necessary to replace the lamp by cutting out the lamp, and the light shielding wall 16 is necessary as a countermeasure against the light leakage of the lamp. When the distance between the lamps 13a and 13b and the incandescent lamps 15a and 15b is short, there is a problem that light unevenness occurs. Furthermore, there is a problem that a large hole must be made in the landing wall 6 in order to embed the box 12. Furthermore, when using a printed board incorporating a microcomputer or the like in the group management control, there is a problem that the printed board must be separately placed in the printed board box 17 in order to avoid the influence of the heat generated by the incandescent lamp.
[0005]
Therefore, by using LEDs instead of incandescent lamps, there is an increasing number of configurations that eliminate lamp replacement work, suppress heat generation, and reduce the size of the light source.
However, in the configuration in which the incandescent lamp is simply replaced with the LED, a light shielding wall is necessary, and the box 12 needs to have a certain thickness. Therefore, it is necessary to make a hole for the box 12 in the landing wall 6. was there.
[0006]
[Means for Solving the Problems]
This invention solves the subject of a prior art by using the surface light emitter of the structure which provided the light source which consists of LED in the one side or several side surface of a flat light-guide plate.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a view corresponding to FIG. 5, and FIGS. 2 (a) and 2 (b) are views showing a surface light emitter.
In the figure, 20 is a hole lantern of the present embodiment, 21 is a face plate having a curved periphery, 22 is a bottom plate, 23 a and 23 b are surface light emitters, 24 is a printed board, and 25 is a hole lantern 20 fixed to the landing wall 6. This is an anchor bolt, and the same reference numerals as those in FIG.
[0008]
30 is a light guide plate made of a transparent acrylic translucent material, 31 is a light source in which LEDs 32 and 33 having different emission colors are alternately arranged on the LED substrate, for example, 32 is a yellow LED and 33 is a red LED. It is. A light source 31 is disposed on two opposing side surfaces of the light guide plate 30, and a display translucent body 13 a or 13 b is disposed on the surface. Moreover, surfaces other than the side surface and the surface on which the light source 31 is disposed are light shielding surfaces. Furthermore, light guide printing is performed on the back surface 30r, and a reflection sheet 35 is provided on the outer and side light shielding surfaces, so that the entire surface of the surface light emitters 23a and 23b is uniformly illuminated. Reference numeral 34 denotes a translucent diffusion sheet provided on the surface of the light guide plate 30.
[0009]
Since the present embodiment has such a configuration, heat generation from the light source can be suppressed as compared with the incandescent lamp, so that the printed board 24 can be incorporated in the main body of the hall lantern 20, and the printed board box 17 is omitted. be able to.
In addition, the hall lantern 20 can be made thinner than in the prior art in which an LED is disposed instead of an incandescent lamp or an incandescent lamp. Therefore, as shown in FIG. 1, it is possible to use a so-called wall-hanging type in which the hall lantern 20 is attached to the surface of the landing wall 6, and a hole for a box to the landing wall 6, which has been conventionally required, can be omitted. .
[0010]
Furthermore, the side surfaces of the surface light emitters 23a and 23b are the light source 31 or the light shielding surface, and there is almost no light leakage. Further, since the surface light emitters 23a and 23b have almost no light unevenness, the display light transmitters 13a and 13b can be formed into a free shape such as a round shape.
[0011]
Further, since two color LEDs are used, for example, the elevator emits the surface light emitter 23a (or 23b) in yellow when the car is assigned to the landing and flashes in red when the car arrives. The display can be changed according to the driving situation. Furthermore, since the surface light emitter itself emits colored light, the color filter can be omitted. Conversely, the LED and the color filter can be used in combination, such as using a color filter with white LED.
Furthermore, the display light-transmitting bodies 13a and 13b can be omitted or changed to a simple transparent cover by printing an arrow or the like on the diffusion sheet 34 on the surface of the light guide plate 30.
[0012]
FIG. 3 is a diagram showing another embodiment of the present invention and corresponds to FIG. The feature of this embodiment is that the light guide plate 40 is divided into a plurality of small light guide plates 41. And the light source 42 is provided so that LED43 may be located in the both sides | surfaces which each small light-guide plate 41 opposes, respectively. The diffusion sheet 34 on the surface of the light guide plate 40 is printed with an arrow.
[0013]
In this embodiment, since each small light guide plate 41 can be controlled to be lighted independently, for example, by turning on the light guide plate 41 sequentially from the lower small light guide plate 41 in accordance with the operation state of the elevator, it is easier to understand for waiting passengers at the hall. Display can be made.
In FIG. 3, one LED 43 is arranged on each side surface of the small light guide plate 41, but a plurality of LEDs having different emission colors can be arranged on each side surface.
[0014]
In each of the above explanations, the light source made of LED is provided on the two opposite side surfaces of the light guide plate. It is possible to prevent unevenness of light simply by providing.
[0015]
In each of the above-described embodiments, the wall-mounted hall lantern has been described. However, the present invention can also be applied to a hall lantern having a box. Further, the present invention is not limited to hall lanterns, and can be applied to indicator lights such as hall indicator 2 and in-car display device, answering light for hall button 1 and answering light for in-car operation panel.
[0016]
【The invention's effect】
As described above, according to the present invention, since the display device can be made thin, a wall-mounted display device can be realized. In addition, light unevenness can be eliminated by performing appropriate light guide printing, and various displays can be performed by using a plurality of colors of LEDs or by dividing the light guide plate.
