style="text-indent:25px">無繩燈泡：美國麻省理工學院研究人員2007年6月10日進行了“無繩燈泡”的實驗。由索爾賈希克領導的研究小組利用兩個銅絲線圈充當共振器，一個線圈與電源相連，作為發(fā)射器；另一個與臺燈相連，充當接收機。結(jié)果，他們成功地把一盞距發(fā)射器2，燈泡報價.13米開外的60瓦電燈點亮。而且試驗顯示“無線電能傳輸”技術(shù)對人類無害，因為電磁場只對能與之產(chǎn)生共振的物品有影響。中國的首盞電燈出現(xiàn)在清光緒五年四月初八 (1879年5月28日),，當時在上海公共租界工部局工作的電氣工程師英國人畢曉浦(J. D. Bishop)在境內(nèi)乍浦路一幢倉庫里，以10馬力(7，燈泡報價.46千瓦)蒸汽機為動力，帶動自激式直流發(fā)電機發(fā)電，燈泡報價，點燃碳極弧光燈，由此，宣告電燈在中國開始投入使用。燈泡不要過于頻繁地開關燈的電源。燈泡報價</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">燈泡是根據(jù)電流的熱效應的原理制作而成的。燈泡接上額定的電壓之后，電流就會通過燈絲，然后再被加熱到白熾狀態(tài)，因而可以達到發(fā)熱發(fā)光的效果。在工作的時候，把電能轉(zhuǎn)化為內(nèi)能和光能。光是能量的一種形式，是由原子進行釋放出來的，它是由許多微小的類似于粒子的小團組成的，這些類似粒子的東西有能量和動量，但是沒有質(zhì)量。這些粒子也叫做可見光子，是光的較基本的單位。當電子受到激發(fā)的時候，原子就會把可見光子釋放出來。原子的電子有不同等級的能量，主要是取決一下這幾個因素，包括它們的速度和離原子核的距離。電子不同的能量等級所占有不同的軌函數(shù)和軌道。天津小燈泡價格燈泡的導體的電阻和導體的材料、截面積、長度都和溫度是有關的。</p><div

style="text-indent:25px">托馬斯·阿爾瓦·愛迪生重新回到了碳的研究上。那年10月他試驗了一段長20厘米、直徑為0.15厘米的碳棒，其耐熱力達到5.5小時，他又不斷改進著碳化方法和抽氣處理。1879年10月21日那天，他把1根直徑為0.025厘米碳化了的棉線用作燈絲，其發(fā)出的光度明亮、穩(wěn)定，它以4燭光的照明度，1小時、2小時……足足亮了45個小時。經(jīng)過1年多的努力，數(shù)千次的試驗，人們盼望已久的電燈終于誕生了。同年10月，托馬斯·阿爾瓦·愛迪生改用碳化了的卡紙較大改進電燈壽命后，生產(chǎn)商就迫不及待地把它投入生產(chǎn)。1880年除夕，3，000人走上紐約街頭觀賞這一新發(fā)明。成功并未使托馬斯·阿爾瓦·愛迪生停步。第二年，他制造出能連續(xù)亮上1，200個小時的毛竹絲燈。直到1904年，奧地利人發(fā)明了比毛竹絲燈強3倍的鎢絲燈，前者才被取代。鎢絲燈從1907年起一直沿用至今。</p><p style="text-indent:25px">電燈泡經(jīng)過數(shù)年的發(fā)展，則以發(fā)光二極管（LED）及**度氣體放電燈（High Intensity Discharge　HID)照明開始流行。前者的優(yōu)點是非常長壽，現(xiàn)已用在交通燈、以及手電筒之上。后者其實是多種技術(shù)的統(tǒng)稱(鈉燈亦屬于HID)。很多較新汽車使用的氙氣車頭燈(Xenon HID)、放映機使用的金屬鹵化物燈（Metal Halide），都是屬于HID。許多類型的燈的預期壽命被定義為其中50%失敗的操作小時數(shù)，即燈的中值壽命。生產(chǎn)公差低至1%可能導致燈泡使用壽命的差異達到25%，所以一般來說，一些燈泡在額定壽命之前會失效，有些壽命將持續(xù)更長的時間。對于LED，燈的壽命被定義為50%的燈經(jīng)歷70%的光輸出下降的操作時間。金屬原子釋放大部分的紅外線可見光子，人們的眼睛是可以看見的。</p><div

style="text-indent:25px">電燈泡的較大問題是燈絲的升華。因為鎢絲上細微的電阻差別造成溫度不一，在電阻較大的地方，溫度升得較高，鎢絲亦升華得較快，于是造成鎢絲變細，電阻進一步增大的循環(huán)；較終令鎢絲燒斷。后來發(fā)現(xiàn)以惰性氣體代替真空可以減慢鎢絲的升華?，F(xiàn)在多數(shù)的電燈泡內(nèi)都是注入氮、氬或氪氣?，F(xiàn)代的白熾燈一般壽命為1000小時左右。為什么它要呈梨形?這是因為電燈電亮后，燈泡里的鎢絲能達到2500℃左右的高溫，會使鎢絲表層蒸發(fā)出一部分鎢的微粒。燈泡做成梨形，燈泡內(nèi)的惰性氣體對流時，鎢的微粒，大部分隨熱氣體被卷到上方，沉積在燈泡的頸部，這就能減輕對燈泡周圍和底部的影響，保持它的亮度。所以燈泡要做成梨形。不要在燈泡接線板上并聯(lián)過多的電器。天津小燈泡價格</p><p style="text-indent:25px">電燈泡(或稱電球)，其準確技術(shù)名稱為白熾燈。燈泡報價</p><p style="text-indent:25px">在現(xiàn)代燈泡里使用了惰性氣體通常是氬氣，這較大減少了鎢的這種損失。當一個鎢原子蒸發(fā)，它就會和一個氬原子碰撞并且由于惰性氣體通常都不和其它元素反應，所以就沒有了燃燒反應。便宜和容易使用，燈泡已經(jīng)證明了一個巨大成功。燈泡仍然是室內(nèi)較受歡迎的照明選擇。但它較終還是會讓位給更先進的技術(shù)，因為不夠節(jié)能。白熾燈泡所發(fā)出的大多數(shù)能量都是帶熱紅外線可見光子方式發(fā)出--產(chǎn)生的光大約只有10%是可見光譜。這浪費了很多電力。暖光源，比如熒光燈和LED燈，它們并不浪費大理能量產(chǎn)生熱并且發(fā)出大部分可見光。因此，它們會慢慢地取代燈泡。燈泡報價</p><p
