電燈泡的問題!電燈泡的問題!15點!急~~~!

我有一些有關電燈的問題,可以的話,請用中、英文回答。

盡量中英都有,但我不要那種英文翻譯網頁或電子辭典翻譯的。

1. 電燈泡是用甚麼做的?

2. 哪些人參與發明電燈泡?

3. 為甚麼大家都說發明電燈泡的人是愛迪生?其他參與發明的人呢?

4. 愛迪生是用了甚麼材料實驗成功?

5. 為甚麼那種材料能當作電燈泡的材料?他有甚麼特性跟別的東西不一樣嗎?

6. 電燈泡從甚麼時候、誰開始研究、發明(哪一年、誰)?

7. 甚麼時候被誰真正發明(哪一年、是愛迪生嗎)?

8. 現在還有繼續發明更新的電燈泡嗎?

以上是我對電燈的疑問,我要做報告用,請各為盡早回答!

    1. 電燈泡是用甚麼做的?

    電燈泡的構造

    Outline of Glass bulb 燈泡外部

    Low pressure inert gas (argon, neon, nitrogen) 低壓惰性氣體 (氬,氖,氮)

    Tungsten filament 鎢燈絲

    Contact wire (goes out of stem) 接觸線 (遠離燈桿)

    Contact wire (goes into stem) 接觸線 (進入燈桿)

    Support wires 支持線

    Stem (glass mount) 燈桿(玻璃座)

    Contact wire (goes out of stem) 接觸線 (遠離燈桿)

    Cap (sleeve) 接頭罩 (套管)

    Insulation (vitrite) 絕緣 (一種玻璃絕緣體)

    Electrical contact 電極接觸

    2. 哪些人參與發明電燈泡?

    In 1802, British scientist Sir Humphry Davy created the first incandescent light by passing the current through a thin strip of platinum,英國科學家 Sir Humphry Davy 在 1802 年將電流通過白金燈絲造出第一個燈炮

    In 1840, British scientist Warren de la Rue enclosed a coiled platinum filament in a vacuum tube and passed an electric current through it. 英國科學家 Warren De la Rue 在 1840 年將白金燈絲線圈裝在真空燈泡中通過電流

    In 1841, Frederick de Moleyns of England was granted the first patent for an incandescent lamp, with a design using powdered charcoal heated between two platinum wires contained within a vacuum bulb. 1841 年英國人 Frederick de Moleyns 得到第一個電燈泡專利 (在真空燈泡的中兩個白金線中夾上加熱的碳粉)

    In 1845, American John W. Starr acquired a patent for his incandescent light bulb involving the use of carbon filaments. He died shortly after obtaining the patent. 1845 年美國人 John W. Starr 得到碳燈絲專利,得到候即去世

    In 1878, British physicist and chemist Joseph Wilson Swan received a British Patent about carbonized paper filaments in an evacuated glass bulb. 1878 年英國物理化學家Joseph Wilson Swan 以真空燈泡中的碳紙燈絲得到英國專利

    2008-12-19 02:53:48 補充:

    1874 年,加拿大人 Henry Woodward 及 Mathew Evans 申請到在充滿氮氣的玻璃圓筒中使用碳棒。但無法商業化而在 1879 年將專利出售給愛迪生

    2008-12-19 02:55:07 補充:

    Edison's first successful carbon filament test was on October 22, 1879, and lasted 13.5 hours.

    2008-12-19 02:55:31 補充:

    Edison continued to improve this design and by Nov 4, 1879, filed for a U.S. patent (U.S. Patent 0,223,898) for an electric lamp using "a carbon filament or strip coiled and connected ... to platina contact wires."

    2008-12-19 02:55:48 補充:

    Although the patent described several ways of creating the carbon filament, it was not until several months after the patent was granted that Edison discovered that a carbonized bamboo filament could last over 1200 hours.

    2008-12-19 02:56:10 補充:

    愛迪生碳燈絲的第一次成功試驗在 1879 年 10 月 22 日,維持了 13.5 個小時。之後繼續改進,在 1879 年 11 月 4 日以“使用碳燈絲或絲圈與鉑線連接”申請燈泡專利。得到此專利數月之後愛迪生才真正以竹碳燈絲維持了 1200 小時

    2008-12-19 02:56:27 補充:

    On December 13th 1904, Aleksandar Just and Ferenc Hanaman were granted a Hungarian patent (No. 34541) for a tungsten filament lamp, which lasted longer and gave a brighter light than the carbon filament. 1904 年,Aleksandar Just 和 Ferenc Hanaman 以鎢燈絲得到匈牙利專利,比起碳燈絲更亮更持久。

    2008-12-19 02:56:55 補充:

    1910 William David Coolidge had invented an improved method of making tungsten filaments. 1910 年,美國 GE 公司 William David Coolidge 改良鎢絲的製造方法。

    8. 現在還有繼續發明更新的電燈泡嗎?

    Halogen lamps 鹵素燈泡,Incandescent arc lamps 熾熱電弧燈泡,Fluorescent lamp 螢光燈泡 (日光燈泡),LED lamp 發光二極管
