<h2 class="wp-block-heading"><span id="toc1">LEDライト使ってますか？</span></h2>



<p class="wp-block-paragraph">夜の散歩などの普段使いから、防災、探検に至るまで、省電力と高照度のLEDライトは便利なシロモノです。</p>



<p class="wp-block-paragraph">最近ではめっきり見かけなくなりましたが、前時代的な、単１電池を入れて豆電球で照らす懐中電灯が、普段使わないせいで放置されたまま・・・というのであれば、いざという時のためにも LEDライトに更新することをオススメします。裸電球に比べ圧倒的省エネルギーでとても明るい携帯LEDライト、1、2本家にあるだけで頼りになります。</p>



<p class="wp-block-paragraph"><strong>また、カバンに１本入れていると、地震などの大災害にいつ巻き込まれるか分からない昨今、生存可能性に歴然とした差が出ます。</strong></p>



<p class="wp-block-paragraph">スマホにライトが付いてるじゃないかと思う人もいるかと思いますが、近年のスマホのLEDはフラッシュを兼ねるため高照度化が進んだおかげでまぁまぁな電池食いです。</p>



<p class="wp-block-paragraph"><strong>目の前を最低限照らすだけでよい状況で、命綱となるスマホの電池を消耗するのは得策ではありません。</strong></p>

<h2 class="wp-block-heading"><span id="toc2">LEDライトのおすすめ価格帯</span></h2>



<p class="wp-block-paragraph">そんなLEDライトも数多のメーカーがあり、どれを選んだものやらという感じです。１００円から数千円、数万円のものまで、値段もバラバラ、どのあたりの価格帯を買えばいいのでしょうか？</p>



<p class="wp-block-paragraph"><strong>結論から言うと、３千円〜５千円くらいのモデルを買うのが良いでしょう。</strong></p>



<p class="wp-block-paragraph">このクラスだと、ケーシングが金属製で経年劣化に強く、放熱面でも安心感があり、また持ち運びやすいサイズであることが多いです。</p>



<p class="wp-block-paragraph">まず千円以下のモノは高照度といっても、砲弾型 LEDを並べただけのもので、粗悪なものが多いです。大抵の場合、使い始めて１ヶ月以内に何個かのLEDが死にはじめ、チカチカと接触不良のような点滅をしたり、ひどいものでは、熱を帯びて中の回路が切れてそのままご臨終というモデルも未だに存在します。</p>



<p class="wp-block-paragraph">安物は本体がプラ製で水分が中に入りやすく、回路自体がサビていつの間にか腐っているというのもよくあります。</p>

<h2 class="wp-block-heading"><span id="toc3">電池の種類は？</span></h2>



<p class="wp-block-paragraph">次に電池です。単３電池２本で動くモノと、単４電池３本を電池ホルダーに入れてから使うものが主流でしたが、近年は充電式リチウム電池のものが増えています。</p>



<p class="wp-block-paragraph">普段から充電して、夜の散歩や帰宅時に使っているのであれば良いのですが、災害用、防災用と考えると、いざという時まで、使わないことが多いでしょう。</p>



<p class="wp-block-paragraph"><strong>よって、防災用の場合、充電池タイプは最悪電池がダメになっているまであるので、オススメできません。</strong></p>



<p class="wp-block-paragraph">またリチウムポリマー電池の多くが衝撃や熱にさらされると痛むので、防災用としてはかなり微妙です。なので、自分は汎用電池で動くモノをオススメしたいです。</p>



<p class="wp-block-paragraph">また電池関連では、購入後気をつけて欲しいのが電池をいれるケースがギリギリではないか。びっくりするくらい単三電池がシンデレラフィットで入れるときにムニューっと抵抗を感じるとかいうケースはハズレです。万一電池に不具合があって電池が膨張したときに取り出し不能になってゴミと化します。</p>



<p class="wp-block-paragraph">個人的な好みでは、単３タイプがオススメです。というのも単４型のものは、電池ボックスに電池を詰めて本体に戻さないといけない反面、単３電池の場合は、本体を開けてストンと取り出して入れ替えるだけ、多くの商品が単３、２本式なので買い置いた電池も大半が４本入りですから、無駄が出にくいのです。</p>



<p class="wp-block-paragraph">また、単４だと単４電池３本という新品を入れると１本余り、これが地味に溜まっていって使いにくいというのもあり、自分は単３電池式をオススメするわけです。</p>



<p class="wp-block-paragraph"><strong>大きく照らすものは単二の二、三本で動くものがオススメです。</strong></p>


<div class="ad-area no-icon ad-shortcode ad-fluid ad-label-visible cf" itemscope itemtype="https://schema.org/WPAdBlock">

          </div>

</div>




<h2 class="wp-block-heading"><span id="toc4">明るさはどのくらい？</span></h2>



<p class="wp-block-paragraph">続いて、明るさです。ルーメンという明るさの光の強さを示す単位があるのですが、近年のLEDの高性能化においてあまり大きく問題ではなくなっている場合が多いです。</p>



<p class="wp-block-paragraph">単3、単2電池で動くものは、充電式リチウム電池のものより、駆動時間も明るさも上なのですが、先の理由で防災用としてはオススメしません。</p>



<p class="wp-block-paragraph">ここ１０年くらいのLEDの性能アップのおかげで、だいたい小型のものでも２〜３ｍ先を十分に照らして数時間程度は駆動可能なものが多くなっています。単４電池１本で数時間動くというものであれば、十分鞄の奥に防災用に入れて置いて損はありません。</p>



<p class="wp-block-paragraph"><strong>防災用という観点では、水につけると電池が活性化して動き出すというタイプのものは、災害時に頼りになるかもしれません。泥水や唾液でも動くので安心です。</strong></p>

<h2 class="wp-block-heading"><span id="toc5">その他のポイント</span></h2>



<p class="wp-block-paragraph"><strong>加えて大事なのが「点滅モードの有無」です。</strong></p>



<p class="wp-block-paragraph">多くのLEDライトに、ピカピカと点滅を繰り返して目眩がしそうになるモードが実装されています。点滅機能、ストロボ機能などと呼ばれ、これは消費電力量が減るために長く、そして目立つために事故防止に・・・というものなのですが、ピカピカとうっとおしいことこの上ないので、自転車にでも搭載しない限り不要です。</p>



<p class="wp-block-paragraph">しかも大半の商品において、この点滅モードが誤作動で入る（温度変化での電圧変化でスイッチが入る、接触不良で勝手に入る）ことが多く、普通点灯に戻すために、何度もカチカチしなくてはいけないという呪いにかかる可能性が濃厚です。</p>



<p class="wp-block-paragraph"><strong>点滅モードは個人的にはダメゼッタイです。</strong></p>

          </div>

</div>




<h2 class="wp-block-heading"><span id="toc6">ヘルドクターおすすめのLEDライト</span></h2>



<p class="wp-block-paragraph">様々なメーカーがありますが、最初に述べた通り、３〜５千円ランクで選べば、一般的な用途では十分なものが大半です。個人的には生活防水が付いており、１００ルーメン以上で、単３電池２本で動くもの・・・をおすすめします。</p>



<p class="wp-block-paragraph">充電式リチウムポリマー電池型のものは、パワフルでUSBで充電できたり良さそうなのですが、だいたい肝心な時に電池切れを起こしていて役に立たないことが多いのでオススメしません。</p>



<p class="wp-block-paragraph"><strong>また、初期不良も相応にあるので、購入したらまずは１０分〜３０分付けっぱなしにしてみて様子をみておいたほうが良いです。</strong></p>



<p class="wp-block-paragraph">ノーブランドものでもお得かどうかは、その場で評判を検索してみて、先人の知見を参考にしてもいいかもしれません。</p>



<p class="wp-block-paragraph">個人的に、今までの条件に合致してて手頃だと思うものを以下にご紹介しておきます。</p>

<h2 class="wp-block-heading"><span id="toc7">使う電池はリチウム乾電池が良い</span></h2>



<p class="wp-block-paragraph">LEDライトに使用する電池は、リチウム乾電池がおすすめです。</p>



<p class="wp-block-paragraph">リチウム乾電池はリチウムポリマーとは違い、使いきり電池で、液漏れをまず起こさない点が優れています。また長期保存に強いため、災害時まで保管しておいても使えることが多いという利点があります。</p>



<p class="wp-block-paragraph">ボタン電池がよく知られていますが、乾電池タイプも割高に見えますが売られています。持ちもパワーも申し分ないので、非常時に備えるには最適な電池です。</p>

<p>機械王の休日、第61回をお送りします。たびたび、100均のダイソーからあれこれと素材を見つけてくるPOKA先生ですが、しかし、それは時として<strong>「どこまで使えるか」「部品の信頼性はどの程度か」といった部分を、地道に検証</strong>した上での事でもあります。</p>
<p>今回見つけたのはあるLEDライト。実際の検証作業を見ていきましょう。</p>

<h2 class="wp-block-heading"><span id="toc1">ダイソーの白色COB型LEDライト</span></h2>



<p class="wp-block-paragraph">ダイソーで、<strong>単四アルカリ電池一本で動く白色COB型のLEDライト</strong>が売られているのを見つけました。</p>



<a href='https://www.cl20.jp/portal/wp-content/uploads/2019/08/cob.jpg'><img loading="lazy" decoding="async" width="225" height="300" src="https://www.cl20.jp/portal/wp-content/uploads/2019/08/cob-225x300.jpg" class="attachment-thumbnail size-thumbnail" alt="" srcset="https://www.cl20.jp/portal/wp-content/uploads/2019/08/cob-225x300.jpg 225w, https://www.cl20.jp/portal/wp-content/uploads/2019/08/cob-500x667.jpg 500w, https://www.cl20.jp/portal/wp-content/uploads/2019/08/cob.jpg 600w" sizes="(max-width: 225px) 100vw, 225px" /></a>



<p class="wp-block-paragraph"><strong>COBとは「Chip On Board」の略で、アルミ基板上に直接LEDチップが実装されているタイプのもの</strong>で、LEDライトといって想像する、あのつぶつぶ感がなく、<strong>発光効率が良くて明るいのが特徴</strong>です。</p>



<p class="wp-block-paragraph">しかし、単四アルカリ電池一本では、1.5Vしか得られません。白色LEDを光らせるには3V以上は欲しいので、そのままでは動作不能のはず・・・<strong>つまり、小さいながらも中に昇圧回路が入っている事になります。</strong></p>



<p class="wp-block-paragraph">100円で昇圧回路が手に入るのなら、これはとても魅力的。さっそく、どのようなものが入っているのか、調べてみました。</p>

<h2 class="wp-block-heading"><span id="toc2">LEDライトの分解</span></h2>



<p class="wp-block-paragraph">この手の小さいものにありがちですが、ネジ止めではなくはめ込みで固定されています。マイナスドライバーなどでこじる事で破壊・・・分解できました。</p>

<p class="wp-block-paragraph">どうやら、<strong>5Vの定電圧レギュレーターのようだという事がわかりました。</strong>通常、LEDの駆動は定電流レギュレーターとなるのですが・・・どうにも、挙動としては怪しい感じです。</p>



<p class="wp-block-paragraph">電子負荷を定電流モードで動作させて、負荷電流を変えながら具合を見てみると、100mAを越えたあたりで出力が不安定になってきました。</p>



<p class="wp-block-paragraph">結局、<strong>100mA辺りで動作不能</strong>となるので、この付近で電流制限動作をしているようですね。電流リミッタがあるのかもしれません。しかし、そうと分かればその範囲での利用を考えるだけです。</p>



<p class="wp-block-paragraph"><strong>こうした事を調べるのも、電子工作には必要な事である。地道な検証作業は大事だぞ、諸君！</strong></p>

<p>機械王の休日、第26回をお送りします。近頃はLEDに取って代わられつつある蛍光灯ですが、POKA先生からしてみれば、これもまた身近な素材のひとつとなります。今回は、蛍光灯の仕組みと、使われている蛍光物質についての話をお送りしましょう。</p>

<h2><span id="toc1">蛍光灯の蛍光体</span></h2>
<p>最近は明かりといえばLEDですが、部屋の照明なら、一昔前は蛍光灯が一般的でした。<strong>この蛍光灯、なぜ光るのか、まず仕組みを簡単に説明しましょう。</strong></p>
<p>古典的な蛍光灯は、管の内部にアルゴン（ないし混合希ガス）と気体の水銀が封入されています。<strong>放電によって</strong>この水銀蒸気を励起して<strong>短波長の紫外線を発生</strong>させて、やはり管内に塗布されている<strong>蛍光体をこの紫外線で光らせる事で、白色光を得ています。</strong></p>

<p>今回、注目したいのは、この蛍光体の方です。種類としては、ケイ酸カルシウムやタングステン酸カルシウムなどが用いられているようです。さっそく、蛍光灯を破壊して<strong>この蛍光体を取り出してみましょう！</strong></p>

<p>この通り、せいぜいが<strong>弱く青っぽく光る程度で、とても白色とは呼べない状態</strong>です。365nmの紫外線では、ほとんど蛍光反応を示さない事がわかりました。</p>
<p>出力という意味では、最近は強力な365nmのLEDも調達できます。しかしながらこの場合は出力の問題ではなく、<strong>より短い波長の高エネルギーな紫外線でないと駄目</strong>なようです。</p>

<p>というわけで、<strong>今度はハンディー殺菌灯の光を当ててみます。</strong></p>

<p><strong>この通り、鮮烈な白色蛍光となりました。殺菌灯からは、254nmと185nmの大変短い波長の紫外線が出ています。</strong>今度は試しに、管の内側ではなく、外側から照らしてみましょう。</p>
<p>

<p>管外から当てた光では、白色蛍光は観察できませんでした。この事から、<strong>254nm＋185nmの光線は、管で遮蔽されてる</strong>ことが分かります。</p>

</p>
<p>蛍光灯の蛍光体は粉状で、このように指で擦る程度で集める事が可能です。<strong>短波長で白色を得たい場合に応用できるかも</strong>しれません。</p>
