中文摘要 | 日光燈既省電發光效率又高,是最被廣泛使用的照明設備,然而一般的書籍卻很少介紹到它。又因日光燈管在點亮前後,其阻抗差別甚大,故要了解日光燈的工作原理,就首先要了解它的起動過程。日光燈屬於崩潰元件,故需外接一安定器,以穩定其操作電流。螢光燈燈管須要有很高的起動電壓,但若伴隨有電極燈絲的預熱,則可降低起動電壓。一般型的起動,屬機械式接點的on/off,約需3-5秒時間完成起動,而立即起動為電子式的快速 on/off,則僅需約0.5秒的時間。 |
英文摘要 | The fluorescent lamps are not only with high efficiency but also saving electrical power. They are the most popular lighting equipments, however, very few books mention them. And there are much differences of impedances between before and after starting, so, to understand their working, starting process must be known firstly. The fluorescent lamps belong to broken-down devices, therefore, a stabilizer (ballast) is essential to stabilize their working current. The lamps need very high starting voltages, but can be much lower with the preheat of electrical-poles. The common starting process belong to on/off of mechanical connection, it takes about 3 to 5 seconds to finish, while the instant starting process belong to on/off of electronic connection, it takes about only 0.5 seconds to complete. |
