1.BAICHIDENG


白熾燈又叫做電燈泡,它的工作原理是電流通過燈絲(鎢絲,熔點達3000多攝氏度)時產生熱量,螺旋狀的燈絲不斷將熱量聚集,使得燈絲的溫度達2000攝氏度以上,燈絲在處于白熾狀態時,就象燒紅了的鐵能發光一樣而發出光來。燈絲的溫度越高,發出的光就越亮。故稱之為白熾燈。白熾燈發光時,大量的電能將轉化為熱能,只有極少一部分(可能不到1%,沒計算過)可以轉化為有用的光能。 白熾燈發出的光是全色光,但各種色光的成份比例是由發光物質(鎢)以及溫度決定的。比例不平衡就導致了光的顏色的偏色,所以在白熾燈下物體的顏色不夠真實。 白熾燈的壽命跟燈絲的溫度有關,因為溫度越高,燈絲就越容易升華。日光燈兩端發黑過程是:鎢絲的升華直接變成鎢氣,這些鎢氣體遇到溫度較低的燈管壁又凝華在燈管壁上而發黑的,當鎢絲升華到比較細瘦時,通電后就很容易燒斷,從而結束了燈的壽命。所以白熾燈的功率越大。
