In the early nineteenth century, people began to use gas (gaslight), but the gas pipeline supply by a leak or blockage, very easy to have an accident, people for illumination of reform, very ardent.In fact, Edison for himself set the mission impossible: in addition to improve lighting, but also of Thomas Edison electric light Create a set of power supply system.And he and the dream LuoYuan buddies, sleepless do 1600 repeatedly heat-resistant material and more than 600 plant fiber experiment, only produced the first carbon wire bulb, can a burning 45 hours.Later he more on this basis, the method of continuous improvement manufacture can ignite 12 hours finally came out with the ZhuSi bulbs.The 19th century the 1980s, Edison electric light career succeeded, this success than any previous achievements brought him reputation.In the 1980s, before he had little mistake, intermediate later, although he has made great achievements, but also common occurance of failure.Edison's most not commendable actions is one of his criticism alternating current, say it has side effects, likely cause of death and injury, but he did not add details.So somebody said, "as he such a mess out many inventions that people about others' new invention saurday attack, this is very contradictory things." He opposes the use of alternating current and direct current, so the approve a fierce debate and stubborn in failure.In this respect, reflects the Edison became a celebrity after the stubbornness of started to foster old-fashioned shortcomings.
19世紀(jì)初，人們開始使用煤氣燈(瓦斯燈)，但是煤氣靠管道供給，一但漏氣或堵塞，非常容易出事，人們對(duì)于照明的改革，十分殷切。事實(shí)上，愛迪生為自己訂定了一個(gè)不可能的任務(wù)：除了改良照明之外，還要愛迪生發(fā)明的電燈創(chuàng)造一套供電的系統(tǒng)。于是他和夢(mèng)羅園的伙伴們，不眠不休的做了1600多次耐熱材料和600多種植物纖維的實(shí)驗(yàn)，才制造出第一個(gè)炭絲燈泡，可以一次燃燒45個(gè)鐘頭。后來他更在這基礎(chǔ)上不斷改良制造的方法，終于推出可以點(diǎn)燃1200小時(shí)的竹絲燈泡。19世紀(jì)80年代中期，愛迪生的電燈事業(yè)獲得了成功，這一成功比以往任何成就給他帶來的聲譽(yù)都大。在80年代中期以前，他很少有失誤，中期以后，盡管他也取得了很大成就，但失敗也是屢見不鮮的。愛迪生最不值得稱贊的行為之一就是他批評(píng)交流電，說它有副作用，可能造成死亡與損傷，但他未加具體說明。所以有人說，“像他這樣一個(gè)自己搞出了許多發(fā)明創(chuàng)造的人竟然對(duì)別人的新發(fā)明大加攻擊，這是很矛盾的事。” 他反對(duì)使用交流電而贊成直流電，因而在一場(chǎng)激烈而固執(zhí)的論戰(zhàn)中敗北。在這方面，反映出了愛迪生成為名人之后漸漸滋生的頑固守舊的缺點(diǎn)。
