【発明の属する技術分野】
本発明は、被写体に光を照射して写像を得る照明器具付き鏡に関し、特に被写体が髭剃りや化粧等を行いたい利用者である場合に、点灯時の眩しさを抑え、また急激に周囲の明るさがが明るくなったり暗くなったりすることを抑えた照明器具付き鏡に関する。
【0002】
【従来の技術】
従来、照明器具付き鏡は、鏡とは別に鏡の上部に白熱ランプや直管形蛍光ランプを用いた照明器具を配設しており、配設された照明器具は鏡面から飛び出しているのが一般的である。
しかし、このように鏡の上部に照明器具を配設すると、被写体のあごや首に影が生じやすく髭剃りや化粧がしづらいため、長方形の化粧鏡の上端及び左右両端に沿って蛍光灯の照明ボックスを配置し、更にカウンター側を照らす下部照明を化粧鏡の下端に配置した事例があった(例えば特許文献1参照)。
【0003】
また、同様な目的で、鏡の周りを照明枠で囲み、この枠中に鏡の各辺に対応させて1個づつの電球を配置した事例もあった(例えば特許文献2参照)。さらに、化粧鏡の下側を除く全外周辺部に蛍光灯を配置すると共に、化粧鏡の下側の両端部と上側の両端部に白熱灯を配置した事例もあった(例えば特許文献3参照)。

【発明が解決しようとする課題】
しかしながら、従来の照明器具付き鏡においては、各々の照明の点灯タイミングをずらす工夫は無く、全ての方向の照明が瞬時に点灯してしまうため、特に視野に入りやすい左右からの照明の光により眩しさを感じ、不快感を生じるといった問題を有していた。
また、消灯時も目が明るい環境になれた状態で、全照明が明るい環境から急に暗い環境へ変わるために暗順応するまでの間は周囲がよく見えないといった問題も有していた。
【0006】
本発明は、上記課題を解決するためになされたもので、本発明の目的は、照明点灯時の眩しさを抑えつつも、全ての照明器具が瞬時に点灯・消灯することによって周囲が急に明るくなったり暗くなったりすることを抑えた照明器具付き鏡を提供することにある。
【0007】
【課題を解決するための手段】
上記目的を達成する為に請求項1では、前記上部照明のみ、或いは上部、下部の照明を所定の明るさで点灯し、左右の照明は点灯後に所定の時間をかけ所定の明るさまで明るくなる照明器具付き鏡とした。
【0008】
これにより、左右の照明はどうしても上部、下部の照明に比べ視野に入りやすく、点灯時の眩しさを感じやすいため、視野に入りにくい上部の照明のみ、或いは上部、下部を両方の照明を左右の照明より先に点灯し、左右の照明を例えば1分程度かけ所定の明るさまで徐々に明るくすることによって、左右各々の照明から急に眩しい光が目に入り眩しさを生ずるのを防ぐことができる。
【0009】
請求項2では、請求項1の発明の場合において、前記照明器具が消灯時所定の時間をかけ徐々に暗くなるようにした。
【0010】
これにより、使用者の目が明るい環境になれた状態から、全ての照明器具が瞬時に消灯しまわりが急に暗くなることによって、暗順応するまでの間、周囲がよく見えなくなるのを防ぐことができる。
【0011】
請求項3では、請求項1又は2の発明の場合において、周囲の明るさを検出する明るさセンサを備えるとともに、該明るさセンサからの信号を元に、前記照明器具の点灯状態が各々異なった状態で切り替わるようにした。
【0012】
これにより、周囲が所定の明るさ以上であれば、全ての照明器具が瞬時に点灯し、周囲が所定の明るさ以下のとき、周囲が暗いと急に明るくなると、余計眩しさによる不快感を感じやすくなるため、視野に入りやすい左右の照明器具のみ1分程度かけて所定の明るさまで徐々に明るくすることによって、急激な明るさの変化により目にかかる負担を軽減できる。
【0013】
また、周囲がある程度明るいときは、例えば、全ての照明を50%程度の明るさで点灯させ、周囲がある程度の明るさ以下の時は100%で点灯させるよう設定しておけば、無駄な電力の消費を抑え、経済的である。
【0014】
【発明の実施の形態】
以下、本発明に係る実施の形態については図面により説明する。
【0015】
図1は本発明である照明器具付き鏡の第1の実施形態に係る正面・側面図、図2は図1のA−A’断面図である。
【0016】
照明器具付き鏡01aは、本体フレーム02に下枠06、左右の側枠07を固定し略箱状に形成され、鏡03を鏡押さえ金具60と下枠06の溝で挟み込んで保持し、鏡押さえ金具60を本体フレーム02に鏡押さえ金具固定ネジ32で固定している。上部照明81aは、光源11を乳白半透明の透過性樹脂製で、光源12を覆うように形成され、カバー固定ネジ31で本体フレーム02に固定されている。また、鏡03の裏面の空間に、左右照明の光源10と、光源の点灯状態を制御する制御回路部20bを配置し、各々が本体フレーム02に固定されている。また、下枠06には、操作することにより光源10、11を点灯・消灯可能な点灯スイッチ72が設けられている。
【0017】
図3に鏡のB−B’断面拡大図を示す。
鏡03は、周縁の左右がガラスの裏面に塗布される銀塗装膜03cをこの部分だけ無くして、銀塗装膜03cを存在させないことで光透過部03aが形成されており、この部分は照射光の眩しさを防ぐために器具内面側03dをブラスト処理している。この光透過部03aの裏側に左右照明の光源10が配置されており、光源からの光がこの部分を通過することにより拡散され柔らかい光となり、前方側へ照射されるように構成されている。
【0018】
図4は本発明である照明器具付き鏡の第1の実施形態に係る電気的な制御回路部のブロック図である。
交流電源71は、記憶回路部82aを経て、上部照明部81a、左右照明部81bに各々接続されている。
上部照明部81aには調光回路部74aと光源11で構成され、調光回路部74aは記憶回路部82aからの信号76aと光源11が接続されている。照明部81bも同様に、調光回路部74bと光源10で構成され、調光回路部74bは記憶回路部82aからの信号76bと光源75bが接続されている。
【0019】
調光回路部74a、74bは、信号76a、76bを受け、上部照明の光源11に対しては定格の明るさ又は所定の調光量で瞬時点灯させ、左右照明の光源10に対しては、所定の調光量まで徐々に明るくしたり(以降、フェードインと称する)、逆に徐々に暗くしたり(以降、フェードアウトと称する)できるようになっている。記憶回路部82aには、光源10、11の調光量、フェードイン・フェードアウトの要否、かつ、変更できるようになっており、それらの変更は各種設定つまみ(図示せず)の操作によるものである。
【0020】
図5に各照明の点灯動作の一例を示す。
使用者が髭剃りや化粧などを行うため鏡を利用する際に点灯スイッチ72をオンすると、予め設定された調光量或いはフェードイン・フェードアウトの要否の情報を記憶回路部82あから呼び出し、それらの情報を信号76a、76bによって調光回路部74a、74bに伝達し、調光回路部74a、74bはその情報に基づいて光源10を瞬時点灯、光源11をT1時間かけてフェードインする。使用者の視野に入りやすい左右の照明をフェードインすることにより、左右各々の照明から急に眩しい光が目に入り眩しさを生ずることはない。
【0021】
また、使用者が点灯スイッチをオフすると、上部照明は瞬時に消灯するが、左右各々の照明はT2時間をかけてフェードアウトするようにしているため、全照明が瞬時に消え急激に周囲が暗くなるがないため、急な明るさの変化による使用者の不快感や目にかかる負担を軽減できる。
【0022】
図6に本発明である照明器具付き鏡の第2の実施形態に係る正面・側面図を示す。第1の実施の形態と異なる点は、側枠の略鏡中央高さ付近に明るさセンサーを設け、制御回路部に明るさセンサ判定回路部を設けた点で、他は第1の実施の形態と同様に形成されている。
【0023】
図7は本発明である照明器具付き鏡の第2の実施形態に係る電気的な制御回路部のブロック図である。
【0024】
交流電源71は、明るさ判定回路部・記憶回路部82aを経て、照明部81a、照明部81bに各々接続されている。照明部81aには調光回路部74aと光源75aで構成され、調光回路部74aは明るさ判定回路部・記憶回路部82bからの信号76aと光源75aが接続されている。照明部81bも同様に、調光回路部74bと光源75bで構成され、調光回路部74bは明るさ判定回路部・記憶回路部82bからの信号76bと光源75bが接続されている。
【0025】
調光回路部74a、74bは、信号76a、76bを受け、光源75a、75bに対し、定格の明るさでの点灯や所定の調光量で点灯、或いは所定の調光量まで徐々に明るくしたり(以降、フェードインと称する)、逆に徐々に暗くしたり(以降、フェードアウトと称する)できるようになっている。明るさ判定回路部・記憶回路部82bには、明るさセンサ79が接続されている。
【0026】
また、明るさ判定回路部・記憶回路部82には、光源75a、75bの調光量、フェードイン・フェードアウトの要否、明るさ判定のための閾値が記憶されており、かつ、変更できるようになっており、それらの変更は各種設定つまみ(図示せず)の操作によるものである。明るさセンサ79の周辺の明るさ判定のための閾値は二つ設定されており、明るさセンサ79の周辺の明るさが一番小さい閾値以下の明るさの場合はモードA、二つの閾値間の明るさはモードB、一番大きい閾値以上の場合はモードCに設定されている。
また、照明部81a、81bは独立して各々を制御できるようにもなっている。
【0027】
次に、動作について説明する。
使用者が髭剃りや化粧などを行うため鏡を利用する際に点灯スイッチ72をオンすると、明るさセンサ79で鏡周辺の明るさを検知し、予め設定してある閾値と比較し、モードを判定する。そして、予め設定されたモード毎の調光量或いはフェードイン・フェードアウトの要否の情報を記憶回路部から呼び出し、それらの情報を信号76a、76bによって調光回路部11、10に伝達し、調光回路部74a、74bはその情報に基づいて光源11、10を点灯、或いはフェードインするものである。また、使用者が点灯スイッチをオフすると、モードに応じて消灯またはフェードアウトする。
【0028】
図8に各照明の点灯動作の一例を示す。明るさセンサ判定のための閾値を、鏡中央部付近に設置された明るさセンサ79周辺が髭剃りや化粧を行うのに十分明るい照度を確保できている場合(A)と、やや暗い場合(B)と、かなり暗い場合(C)とに設定しておく。
【0029】
(A)の場合、鏡周辺が例えば窓から外光や天井照明によって照度が確保されているため、上部の照明は点灯させず、左右各々の照明から、例えば全光出力の50%の弱めの光で使用者を照らし、影やムラを無くし髭剃りや化粧がしやすくする。また、左右の照明は使用者の視野に入りやすく眩しさを感じやすいため、T1時間をかけフェードインするように設定している。
【0030】
(B)の場合、鏡周辺の明るさがやや不足しているため、上部照明から、例えば全光出力の50%の弱めの光で使用者を照らし髭剃りや化粧に十分な明るさを確保し、さらに左右各々の照明から上部照明によって使用者のあごや首下に生じる影を緩和することによって、髭剃りや化粧がしやすくなる。
【0031】
(C)の場合、鏡周辺の明るさがかなり不足し使用者が髭剃りや化粧ができない状態のため、上部照明を全光出力の100%で点灯し使用者を照らし髭剃りや化粧に十分な明るさを確保した上で、さらに左右各々の照明から全光出力の100%で、上部照明によってあごや首下に生じる影を緩和することによって、髭剃りや化粧がしやすくなる。
【0032】
左右各々の照明はT2時間をかけてフェードアウトするようにしているため、全照明が瞬時に消え急激に周囲が暗くなるがないため、急な明るさの変化による使用者の不快感や目にかかる負担を軽減できる。また、全てのモードでフェードアウトの時間をT2時間としているが異ならせても良い。
【0033】
そのモードに応じて、各照明毎に好みの点灯状態や調光量、或いはフェードイン、フェードアウトの要否を予め設定しておくことで、自動的にお気に入りの光を得ることができる。
【0034】
なお、実施例においてモードは三つとしたがこれに限らず、二つでも四つ以上でも構わない。また、光出力を低い場合を50%、高い場合を100%ととしたが、無くてもよく、左右照明のみフェードアウトさせたが、上部照明もフェードアウトさせても良い。
【0035】
また、実施例において点灯・消灯スイッチを本体に設けたが、器具とは別に器具周辺の壁面に取り付けても良い。
【0036】
本実施例では、フェードイン、フェードアウトを時間とともに一定の比率で光出力が増加するようにしたが、一定の比率でなくても良く、明順応、暗順応特性に応じ光出力を変化させても良い。
【0037】
【発明の効果】
本発明は上記構成により次の効果を発揮する。
被写体に光を照射して写像を得る照明器具付き鏡に関し、特に被写体が髭剃りや化粧等を行いたい利用者である場合に、視野に入らない上部或いは上部と下部の照明は瞬時に点灯させ、視野に入りやすい左右各々の照明は所定の明るさで徐々に明るくなるよう点灯させることによって、点灯時の眩しさや不快感を抑えることができる。

[Problems to be solved by the invention]
However, in the conventional mirror with a lighting fixture, there is no contrivance for shifting the lighting timing of each lighting, and the lighting in all directions is turned on instantaneously. There is a problem that the user feels discomfort and causes discomfort.
In addition, there is also a problem that even when the lights are turned off, the surroundings are not clearly seen until the dark adaptation occurs because all the lights suddenly change from a bright environment to a dark environment in a state where the eyes are in a bright environment.
[0006]
The present invention has been made in order to solve the above-described problems, and an object of the present invention is to suppress glare at the time of lighting, but to quickly turn on and off the surroundings by instantaneously turning on and off all lighting devices. An object of the present invention is to provide a mirror with a lighting fixture that suppresses brightening and darkening.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, according to claim 1, only the upper illumination, or the upper and lower illuminations are illuminated at a predetermined brightness, and the left and right illuminations take a predetermined time after being illuminated and become bright to a predetermined brightness. A mirror with an instrument was used.
[0008]
As a result, the left and right lights are more likely to enter the field of view than the upper and lower lights, and it is easy to feel the glare at the time of lighting. By turning on the light before the illumination and gradually increasing the left and right illuminations to a predetermined brightness over, for example, about one minute, it is possible to prevent suddenly dazzling light from entering the eyes from the left and right illuminations from causing glare. .
[0009]
According to a second aspect of the present invention, in the case of the first aspect of the present invention, the lighting fixture is gradually darkened over a predetermined time when the light is turned off.
[0010]
In this way, from the state where the user's eyes are in a bright environment, all lighting fixtures are instantly turned off and the surroundings suddenly darken, preventing the surroundings from becoming invisible until dark adaptation Can be.
[0011]
According to a third aspect, in the case of the first or second aspect, a brightness sensor for detecting ambient brightness is provided, and the lighting states of the lighting fixtures are different based on a signal from the brightness sensor. It is switched in the state where it was set.
[0012]
Thereby, if the surroundings are at or above a predetermined brightness, all the lighting fixtures are turned on instantly, and when the surroundings are at or below the predetermined brightness, if the surroundings suddenly become bright when the surroundings are dark, discomfort due to extra glare is caused. Since it becomes easier to feel, by gradually increasing the brightness of the left and right lighting fixtures that easily enter the field of view to a predetermined brightness in about one minute, the burden on the eyes due to a sudden change in brightness can be reduced.
[0013]
If the surroundings are bright to some extent, for example, all the lights are turned on at about 50% brightness, and if the surroundings are less than a certain brightness, the lighting is set to 100%. It is economical to reduce consumption.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.

These changes are made by operating various setting knobs (not shown). Two thresholds for determining the brightness around the brightness sensor 79 are set. If the brightness around the brightness sensor 79 is less than or equal to the minimum threshold, the mode A is set between the two thresholds. Is set to mode B, and to the mode C when the brightness is equal to or larger than the largest threshold value.
Further, the illumination units 81a and 81b can be controlled independently.
[0027]
Next, the operation will be described.
When the lighting switch 72 is turned on when the user uses the mirror to perform shaving or makeup, the brightness sensor 79 detects the brightness around the mirror, compares the brightness with a preset threshold, and changes the mode. judge. Then, information on the necessity of light intensity or fade-in / fade-out for each preset mode is called from the storage circuit unit, and the information is transmitted to the light adjustment circuit units 11 and 10 by signals 76a and 76b, and the light adjustment is performed. The optical circuit units 74a and 74b turn on or fade in the light sources 11 and 10 based on the information. When the user turns off the lighting switch, the light is turned off or faded out according to the mode.
[0028]
FIG. 8 shows an example of the lighting operation of each illumination. The threshold value for the brightness sensor determination is set to a case where the surroundings of the brightness sensor 79 installed near the center of the mirror can secure sufficient illuminance to perform shaving or makeup (A) and a case where the brightness is slightly dark ( B) and (C) when it is quite dark.
[0029]
In the case of (A), since the illuminance around the mirror is ensured by, for example, external light or ceiling illumination from a window, the upper illumination is not turned on, and the left and right illuminations are reduced by, for example, 50% of the total light output. The light illuminates the user, eliminating shadows and unevenness and making shaving and makeup easier. The left and right lights are set to fade in over T1 time since the user easily enters the visual field of the user and easily feels glare.
[0030]
In the case of (B), since the brightness around the mirror is slightly insufficient, the user can illuminate the user with, for example, a weak light of 50% of the total light output from the upper illumination to secure sufficient brightness for shaving and makeup. In addition, shading and makeup can be easily performed by alleviating shadows generated below the chin and neck of the user by the upper illumination from the left and right illuminations.
[0031]
In the case of (C), since the brightness around the mirror is considerably insufficient and the user cannot perform shaving or makeup, the upper illumination is turned on at 100% of the total light output to illuminate the user and sufficient for shaving and makeup. In addition to ensuring high brightness, 100% of the total light output from each of the left and right illuminations reduces shadows generated under the chin and neck by the upper illumination, thereby making shaving and makeup easier.
[0032]
Since the left and right lights fade out over T2 time, all lights disappear instantly and there is no sudden darkening of the surroundings. The burden can be reduced. Further, the fade-out time is set to T2 time in all modes, but may be different.
[0033]
In accordance with the mode, by setting in advance a desired lighting state, light intensity, or necessity of fade-in or fade-out for each illumination, a favorite light can be obtained automatically.
[0034]
Although the number of modes is three in the embodiment, the number of modes is not limited to three, and may be two or four or more. Also, the case where the light output is low is 50% and the case where the light output is high is 100%. However, the light output may be omitted, and only the left and right illuminations are faded out, but the upper illumination may be faded out.
[0035]
Further, in the embodiment, the on / off switch is provided on the main body, but may be attached to a wall surface around the appliance separately from the appliance.
[0036]
In the present embodiment, the light output is increased at a constant rate with the fade-in and the fade-out with time.However, the light output does not have to be a constant rate, and the light output may be changed according to the light adaptation and the dark adaptation characteristics. good.
[0037]
【The invention's effect】
The present invention has the following effects by the above configuration.
Regarding a mirror with lighting equipment that irradiates light to a subject to obtain a mapping, particularly when the subject is a user who wants to shave or make up, the upper or upper and lower lights that do not enter the field of view are turned on instantly. By illuminating the left and right illuminations that easily enter the field of view with a predetermined brightness, the glare and discomfort at the time of the illumination can be suppressed.
