Description

【0001】
【発明が属する技術分野】
本発明は、両面型時計の発光ダイオードによる内部照明装置に関する。
【0002】
【従来の技術】
従来の両面型時計の内部照明装置においては、円環状又は棒状の蛍光灯を乳白色のアクリル板などの半透過部材からなる時計文字盤の裏側に組み込み文字盤を照らし出している。
【0003】
【発明が解決しようとする課題】
従来の両面型時計の内部照明装置においては、蛍光灯を使用していたため寿命が6000時間程度と短く、公共施設のような場所においては設置される台数が多く交換の難しい高所に設置されるため、交換に多大な手間と費用を要していた。
【0004】
発光ダイオード素子は寿命の点で蛍光灯より優れているが、輝度を上げる工夫としてレンズや反射鏡などで光を集束させるため指向性が強い。均一な明るさで時計の文字盤全体を高輝度照明するためには平面状に多数密集して配列しなければならないため部品コストと製造コストが高くなってしまう。
【0005】
蛍光灯はほぼ全方向に光が放射されるため両面型時計の文字盤と文字盤の間に蛍光灯を配置すれば両面とも照らし出すことができるが、発光ダイオードを平面状に配列して照射すると1つの面しか照明することができず、両面を照らし出すには発光ダイオードを配列したものを各面に1式ずつ用意しなければならず、コストが高くなり取付や交換も面倒であるという問題点があった。
【0006】
本発明は、寿命特性に優れた発光ダイオード素子を発光体に利用し、製造コストを低廉にでき、交換回数の削減や交換の際のメンテナンス性に優れた両面型時計の内部照明装置を提供することを目的としている。
【0007】
【課題を解決するための手段】
上記目的を達成するために、本発明の内部照明装置においては、両面型時計の文字盤間に発光ダイオード素子の取付板を配置し取付板のそれぞれの面に発光ダイオードを等距離に分散配列する。
【0008】
また、取付板の両面あるうち任意に選んだ一方の面として甲面(以下同様)には、隣り合う発光ダイオード素子間の距離が同一になるように配置し、甲と反対面である乙面(以下同様)には甲面で配置した発光ダイオード素子と発光ダイオード素子の中間部の裏側に発光ダイオード素子を配置する。
【0009】
上記発光ダイオード素子の取付板の色は適当な色でよいが、後記する理由により、白色の素材または白色に塗装することが効果的である。取付板はプリント回路基板とし、回路配線を省力化してもよい。
【0010】
さらに、両面型時計の文字盤間において細長い回路基板上に均等間隔で発光ダイオードを表裏交互に配置した複数のユニットを、隣接するユニット同士の発光ダイオードが表裏反対でかつ1つの文字盤に向いた発光ダイオードを等距離に分散して配置されるようにユニットを配置してもよい。
【0011】
また、両面型時計の文字盤間において細長い回路基板上に均等間隔で発光ダイオードを表裏交互に配置した複数のユニットを、一方の発光ダイオードの配置間隔に等しい間隔でかつ発光ダイオード素子より大きい発光ダイオード挿入孔を開けた取付板に発光ダイオードを発光ダイオード挿入孔に通して取付けてもよい。
【0012】
【発明の実施の形態】
発明の実施の形態を実施例にもとづき図面を参照して説明する。
図1において、取付板1のうち、紙面上方を向いている面を甲面、反対側を乙面とし、実線の丸は甲面垂直上方に向けて光を放射するように実装される発光ダイオード2、点線の丸は乙面の垂直上方に向けて複数個実装される発光ダイオード3とする。隣接する発光ダイオード2それぞれが等距離になるよう分散して並べる。
【0013】
隣り合う発光ダイオード2に囲まれた位置に発光ダイオード3を実装する。このように配置することで、甲面、乙面ともに発光ダイオード同士を等距離で分散配置することができる。等距離で並べたときの効果については後述する。また、取付板1を時計内部に組み付けるため螺子孔4を空けるが、螺子孔4を省略し、時計内部には取付板1を挟み込むようにして取り付けても良い。
【0014】
図1の断面aを図2に示す。発光ダイオードの固定は、取付板1に接着する。
作業性や交換を考慮して発光ダイオード取付用のソケットを用いてもよい。なお、配線の作業性をさらに向上させるために取付板をプリント配線基板にしてもよい。なお、取付板1に穴を空け発光ダイオードを反対の面から貫通して取り付けているが、貫通させず光りを放射する面に垂直に並べてもよい。
【0015】
代表的な回路を図3に示す。電源14の高電位側から発光ダイオード15を複数個直列に順方向接続し、電流制御手段として抵抗16で電流を制限し低電位側に接続する。直列にする発光ダイオード15の数は所要の電流を流した際の順方向電圧の合計が電源14の電圧より低くなるようにする。電流値は多く流せば輝度は増すが定格電流を超えないようにする。抵抗16を可変抵抗とすることで、照明の明るさを調節してもよい。この直列回路を、取付板1の全体に並べる発光ダイオード15の個数分だけ電源14に並列接続する。なお、電源14および抵抗16を配置する場所は、設計上の問題で任意の場所で良い。また、電流制限手段として抵抗16の代わりに定電流ダイオードや定電流回路を用いてもよい。
【0016】
図4は、図1で説明した発光ダイオードの実装された取付板を両面用時計の文字盤と文字盤の間に取付けた断面図である。発光ダイオード22から発生した光は文字盤24に向かって放射状に広がる。文字盤24は乳白色のアクリル板で光が拡散透過する。文字盤に当たった光のうち一部は反射し取付板21に戻ってくるが、取付板21の材質を白色または白色塗装することで、発光ダイオード取付板21の表面で光が拡散反射する。白色は、あらゆる可視光を高い反射率で拡散反射するため、発光ダイオード22から直接当たる光と取付板21で拡散反射し再度文字盤に当たる光が重なり合い、発光ダイオード素子の輝度の差が軽減され、文字盤が均一に照らし出される。時計外部より交流100[V]を入力し、電源23にて所要の直流電圧に変換して供給する。電源23からはリード線でLEDと抵抗を結線する。なお、電源は時計内に収納しているが、設計上の問題で外部に配置してもよい。
【0017】
図5は発光ダイオード取付板に発光ダイオードを格子状に配列した場合の文字盤を透過する光の投射図である。発光ダイオード光源51から出た光は放射上に広がるため、投射光50の直径は発光ダイオード素子と文字盤との距離で変化する。発光ダイオード素子を配列する場合格子状に配列する。図6に示すように隣り合う発光ダイオード素子61の間隔を等距離に分散配列すると、投射光60のようになり、より広い配置間隔で均等な照明を実現できる。
【0018】
図7は、プリント基板75に甲面側発光ダイオード74と乙面側発光ダイオード76とを交互に等間隔で実装したものを時計内部に組み付けた正面図である。
甲側の発光ダイオード74と乙側の発光ダイオード76は表裏で交互に実装している。なお、図7では電流制限抵抗と電源は前述と同様なので省略する。プリント基板75の両端には螺子止め孔を空ける。時計ケース71に基板固定金具73を取り付け、基板固定金具73には螺子孔を空け、螺子77でプリント基板75を固定する。
【0019】
図8は、取付板80に孔82と固定用螺子孔81及び取付孔83を空けた正面図である。隣り合う孔82の間隔は等距離で図7における一方の面の発光ダイオードの取付間隔で配列してある。取付孔83は時計内部に組み付けるための孔であるが、時計内部への組み込み方については設計上の問題でどのようなものでもよい。
【0020】
図9は、図7における発光ダイオード74及び76の実装されたプリント基板75を螺子77で図8の取付板80に固定した正面図である。図7の発光ダイオード74及び発光ダイオード76の実装されたプリント基板75を取付板80に固定する際、図8の取付孔82に発光ダイオードを合わせるため交互に上下、又は表裏を反転している。なお、電流制限抵抗及び電源の配置は省略する。83の螺子孔を使い時計ケースへ固定する。
【0021】
図10は図9のb断面図である。孔82を通った発光ダイオード76は発光ダイオード74と反対方向を照明することで両面用時計を同時に内部照明する。
【0022】
【発明の効果】
本発明は以上に説明したように構成されているので、以下に記載されるような効果を奏する。
【0023】
両面用時計の文字盤と文字盤の間に発光ダイオードを両面に取り付けた取付板を配置することにより、簡易な構造でありながら両面の文字盤を内部より照らし出すことができる。
【0024】
また、発光ダイオードを使用することにより発光寿命が飛躍的に伸び、灯具の交換にかかる手間を大幅に削減することができ、交換の際にも1枚の取付板を交換するだけで済むので交換に要する手間も少ない。
【0025】
さらに、発光ダイオードを並べる際に等距離に分散配列し、一方の面の発光ダイオードと発光ダイオードの中間位置に他方の面の発光ダイオードを取り付けることにより両面とも均等配置できることによって均一な文字盤照明ができるだけでなく取付間隔を狭めても容易に発光ダイオードを取り付けることができ、製造の手間の増大を防ぎ製造コストを抑えることができる。
【0026】
また、発光ダイオードの取付板を白色にすることにより発光ダイオードから発せられ文字盤で透過せず反射した光が取付板で拡散反射するので文字盤を透過する光はさらに均一になる。
【0027】
また、発光ダイオードの取付板をプリント基板にすることにより配線の手間を少なくすることができ、製造コストの削減につながる。
【0028】
さらに、細長いプリント基板の両面に表裏交互に同数発光ダイオードを実装し、複数個を表裏または上下反対向きに並べることでプリント基板の総面積を小さくでき、プリント基板のコストを削減することができる。
【0029】
さらに、細長いプリント基板の両面に表裏交互に同じ数だけ発光ダイオードを実装したものを、複数の発光ダイオード孔を等距離に分散配列した取付板に表裏または上下反対向きに取付けることで、前述した理由でプリント基板のコストを削減すると同時に、交換の際に取付板ごと交換できるので交換の手間が少なくて済む。

[Technical field to which the invention belongs]
The present invention relates to an internal illumination device using a light emitting diode of a double-sided timepiece.
[0002]
[Prior art]
In an internal lighting device of a conventional double-sided watch, an annular or stick-shaped fluorescent lamp is incorporated on the back side of a watch dial made of a translucent member such as a milky white acrylic plate to illuminate the dial.
[0003]
[Problems to be solved by the invention]
The conventional internal lighting device of a double-sided watch has a life span of about 6000 hours due to the use of a fluorescent lamp, and is installed in a high place that is difficult to replace in a place such as a public facility where the number of units is large. Therefore, a great deal of labor and expense was required for the replacement.
[0004]
Light-emitting diode elements are superior to fluorescent lamps in terms of life, but they have strong directivity because light is focused by a lens or a reflector as a device to increase brightness. In order to illuminate the entire clock face with high brightness with uniform brightness, a large number of flat dials must be arranged in a dense manner, resulting in high component costs and manufacturing costs.
[0005]
Fluorescent lamps emit light in almost all directions, so if you place a fluorescent lamp between the dials of a double-sided watch, you can illuminate both sides. Then, only one surface can be illuminated, and in order to illuminate both surfaces, one array of light emitting diodes must be prepared for each surface, which increases costs and is troublesome to install and replace. There was a problem.
[0006]
The present invention provides an internal lighting device for a double-sided watch that uses a light-emitting diode element with excellent lifetime characteristics as a light emitter, can reduce the manufacturing cost, and is excellent in reduction in the number of replacements and maintenance in replacement. The purpose is that.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, in the internal lighting device of the present invention, the mounting plates of the light emitting diode elements are arranged between the dials of the double-sided timepiece, and the light emitting diodes are arranged at equal distances on the respective surfaces of the mounting plate. .
[0008]
In addition, on both sides of the mounting plate, one side that is arbitrarily selected is arranged so that the distance between adjacent light-emitting diode elements is the same on the back side (same below), and the opposite side is the front side. In the same manner, the light emitting diode element is arranged on the back side of the intermediate portion between the light emitting diode element arranged on the upper surface and the light emitting diode element.
[0009]
Although the color of the mounting plate of the light emitting diode element may be an appropriate color, it is effective to apply a white material or white for the reason described later. The mounting plate may be a printed circuit board, and circuit wiring may be saved.
[0010]
Furthermore, a plurality of units in which light emitting diodes are alternately arranged on the elongated circuit board at equal intervals between the dials of the double-sided watch are arranged so that the light emitting diodes of adjacent units are opposite to each other and face one dial. The units may be arranged so that the light emitting diodes are arranged at equal distances.
[0011]
Further, a plurality of units in which light emitting diodes are alternately arranged on the elongated circuit board at equal intervals between the dials of the double-sided watch are arranged at intervals equal to the arrangement interval of one light emitting diode and larger than the light emitting diode element. The light emitting diode may be attached to the mounting plate having the insertion hole through the light emitting diode insertion hole.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on examples with reference to the drawings.
In FIG. 1, the surface of the mounting plate 1 facing upward on the paper surface is the upper surface, the opposite side is the front surface, and the solid circle is a light emitting diode mounted so as to emit light toward the upper vertical direction of the upper surface. 2. The dotted circles are the light-emitting diodes 3 that are mounted in the vertical direction above the front surface. The adjacent light emitting diodes 2 are arranged in a distributed manner so as to be equidistant.
[0013]
The light emitting diode 3 is mounted at a position surrounded by adjacent light emitting diodes 2. By arranging in this way, it is possible to disperse and arrange the light emitting diodes at equal distances on both the upper side and the second side. The effect of arranging them at the same distance will be described later. Further, although the screw hole 4 is opened to assemble the mounting plate 1 inside the timepiece, the screw hole 4 may be omitted, and the mounting plate 1 may be sandwiched inside the timepiece.
[0014]
A cross section a of FIG. 1 is shown in FIG. The light emitting diode is fixed to the mounting plate 1.
In consideration of workability and replacement, a socket for mounting a light emitting diode may be used. The mounting plate may be a printed wiring board in order to further improve the workability of wiring. In addition, although the hole is made in the attachment plate 1 and the light emitting diode is penetrated from the opposite surface, it may be arranged perpendicularly to the surface that emits light without penetrating.
[0015]
A typical circuit is shown in FIG. A plurality of light emitting diodes 15 are connected in series in the forward direction from the high potential side of the power supply 14, and the current is limited by a resistor 16 as a current control means and connected to the low potential side. The number of light emitting diodes 15 in series is such that the total forward voltage when a required current is passed is lower than the voltage of the power supply 14. If a large amount of current is applied, the brightness will increase but the rated current will not be exceeded. The brightness of the illumination may be adjusted by making the resistor 16 a variable resistor. This series circuit is connected in parallel to the power source 14 by the number of light emitting diodes 15 arranged on the entire mounting plate 1. It should be noted that the place where the power supply 14 and the resistor 16 are disposed may be any place due to a design problem. Further, a constant current diode or a constant current circuit may be used instead of the resistor 16 as the current limiting means.
[0016]
FIG. 4 is a sectional view in which the mounting plate on which the light emitting diode described in FIG. 1 is mounted is mounted between the dials of the double-sided watch. The light generated from the light emitting diode 22 spreads radially toward the dial 24. The dial 24 is a milky white acrylic plate through which light diffuses and transmits. A part of the light hitting the dial is reflected and returned to the mounting plate 21, but the light is diffusely reflected on the surface of the light emitting diode mounting plate 21 by coating the material of the mounting plate 21 with white or white. White diffuses and reflects all visible light with high reflectivity, so that the light that directly strikes the light emitting diode 22 and the light that is diffusely reflected by the mounting plate 21 and again strikes the dial overlap, reducing the difference in luminance of the light emitting diode elements, The dial is illuminated uniformly. AC 100 [V] is input from the outside of the watch, converted into a required DC voltage by the power source 23 and supplied. From the power source 23, an LED and a resistor are connected by a lead wire. Although the power source is housed in the watch, it may be arranged outside due to a design problem.
[0017]
FIG. 5 is a projection view of light transmitted through the dial when the light emitting diodes are arranged in a grid on the light emitting diode mounting plate. Since the light emitted from the light emitting diode light source 51 spreads on the radiation, the diameter of the projection light 50 changes depending on the distance between the light emitting diode element and the dial. When light emitting diode elements are arranged, they are arranged in a grid pattern. As shown in FIG. 6, when the intervals between the adjacent light emitting diode elements 61 are dispersed and arranged at equal distances, the projection light 60 is obtained, and uniform illumination can be realized with a wider arrangement interval.
[0018]
FIG. 7 is a front view in which the back side light emitting diodes 74 and the front side light emitting diodes 76 are alternately mounted on the printed circuit board 75 at equal intervals.
The light emitting diodes 74 on the back side and the light emitting diodes 76 on the second side are alternately mounted on the front and back sides. In FIG. 7, the current limiting resistor and the power source are the same as described above, and are omitted. Screw fixing holes are formed at both ends of the printed circuit board 75. A board fixing metal fitting 73 is attached to the watch case 71, a screw hole is formed in the board fixing metal fitting 73, and the printed circuit board 75 is fixed with the screw 77.
[0019]
FIG. 8 is a front view in which a hole 82, a fixing screw hole 81, and a mounting hole 83 are formed in the mounting plate 80. The intervals between the adjacent holes 82 are equidistant and are arranged at the mounting interval of the light emitting diodes on one surface in FIG. The mounting hole 83 is a hole for assembling inside the timepiece, but any method for assembling the inside of the timepiece may be used due to a design problem.
[0020]
9 is a front view in which the printed circuit board 75 on which the light emitting diodes 74 and 76 in FIG. 7 are mounted is fixed to the mounting plate 80 in FIG. When fixing the light-emitting diode 74 and the printed circuit board 75 on which the light-emitting diode 76 is mounted to the mounting plate 80, the top and bottom or the front and back are alternately reversed to align the light-emitting diode with the mounting hole 82 of FIG. Note that the arrangement of the current limiting resistor and the power source is omitted. Fix to the watch case using the 83 screw holes.
[0021]
10 is a cross-sectional view of FIG. 9b. The light emitting diode 76 that has passed through the hole 82 illuminates the opposite direction of the light emitting diode 74, thereby simultaneously illuminating the double-sided timepiece.
[0022]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
[0023]
By disposing a mounting plate with light-emitting diodes mounted on both sides between the dials of the double-sided watch, the double-sided dial can be illuminated from the inside with a simple structure.
[0024]
In addition, the use of light-emitting diodes dramatically increases the light-emitting life, greatly reducing the time and effort required to replace the lamp, and only one mounting plate needs to be replaced. Less effort is required.
[0025]
Furthermore, when the light emitting diodes are arranged, they are distributed at equal distances, and the light emitting diodes on the other surface can be evenly arranged by attaching the light emitting diodes on the other surface to the middle position between the light emitting diodes on one surface, thereby providing uniform dial illumination. Not only can the light emitting diode be easily attached even if the attachment interval is narrowed, it is possible to prevent an increase in manufacturing effort and to reduce manufacturing costs.
[0026]
Further, by making the mounting plate of the light emitting diode white, the light emitted from the light emitting diode and reflected without being transmitted through the dial is diffusely reflected by the mounting plate, so that the light transmitted through the dial becomes more uniform.
[0027]
Further, by using a printed circuit board as the mounting plate of the light emitting diode, the labor of wiring can be reduced, leading to a reduction in manufacturing cost.
[0028]
Furthermore, the same number of light emitting diodes are alternately mounted on both sides of the long and narrow printed circuit board, and a plurality of the light emitting diodes are arranged on the front and back or in the upside down direction, whereby the total area of the printed circuit board can be reduced and the cost of the printed circuit board can be reduced.
[0029]
In addition, by mounting the same number of light emitting diodes on both sides of an elongated printed circuit board alternately on the front and back sides, mounting the light emitting diode holes on the mounting plate with the light emitting diode holes arranged at equal distances on the front and back sides or upside down, Thus, the cost of the printed circuit board can be reduced, and at the same time, the entire mounting plate can be replaced at the time of replacement.
