日光燈工作原理

工(gong)作原理是：當開關接通的時候，電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓立(li)即(ji)通過(guo)鎮流(liu)(liu)器(qi)(qi)(qi)和燈(deng)管(guan)燈(deng)絲加到啟輝(hui)器(qi)(qi)(qi)的兩極。220伏的電(dian)(dian)(dian)(dian)壓立(li)即(ji)使啟輝(hui)器(qi)(qi)(qi)的惰性(xing)氣體電(dian)(dian)(dian)(dian)離，產生輝(hui)光放電(dian)(dian)(dian)(dian)。輝(hui)光放電(dian)(dian)(dian)(dian)的熱(re)量使雙金屬片受(shou)熱(re)膨脹，兩極接觸。電(dian)(dian)(dian)(dian)流(liu)(liu)通過(guo)鎮流(liu)(liu)器(qi)(qi)(qi)、啟輝(hui)器(qi)(qi)(qi)觸極和兩端燈(deng)絲構(gou)成通路。燈(deng)絲很快被電(dian)(dian)(dian)(dian)流(liu)(liu)加熱(re)，發射出大量電(dian)(dian)(dian)(dian)子。

這時，由于啟(qi)輝器(qi)兩(liang)(liang)(liang)極閉合，兩(liang)(liang)(liang)極間電(dian)(dian)壓(ya)為零，輝光放電(dian)(dian)消失，管(guan)(guan)內(nei)溫度(du)降低；雙金屬片自動(dong)復位，兩(liang)(liang)(liang)極斷(duan)開(kai)。在(zai)兩(liang)(liang)(liang)極斷(duan)開(kai)的(de)瞬間，電(dian)(dian)路電(dian)(dian)流(liu)突然切斷(duan)，鎮流(liu)器(qi)產生很大(da)的(de)自感電(dian)(dian)動(dong)勢，與電(dian)(dian)源電(dian)(dian)壓(ya)疊加后(hou)作用(yong)于管(guan)(guan)兩(liang)(liang)(liang)端(duan)(duan)。燈絲受(shou)熱時發射出來(lai)的(de)大(da)量電(dian)(dian)子，在(zai)燈管(guan)(guan)兩(liang)(liang)(liang)端(duan)(duan)高電(dian)(dian)壓(ya)作用(yong)下，以極大(da)的(de)速度(du)由低電(dian)(dian)勢端(duan)(duan)向高電(dian)(dian)勢端(duan)(duan)運動(dong)。

在加速(su)運動(dong)的(de)(de)(de)過程中，碰撞管內氬氣分子(zi)，使(shi)之迅速(su)電離(li)(li)(li)。氬氣電離(li)(li)(li)生熱，熱量使(shi)水(shui)銀產生蒸氣，隨之水(shui)銀蒸氣也(ye)被電離(li)(li)(li)，并發出(chu)強烈的(de)(de)(de)紫(zi)(zi)外(wai)線(xian)(xian)。在紫(zi)(zi)外(wai)線(xian)(xian)的(de)(de)(de)激發下，管壁內的(de)(de)(de)熒光粉(fen)發出(chu)近乎白色的(de)(de)(de)可見(jian)光。

日光燈(deng)正常發光后。由(you)于(yu)(yu)交流(liu)電(dian)(dian)(dian)(dian)(dian)不斷通過鎮(zhen)流(liu)器的(de)(de)線(xian)圈，線(xian)圈中(zhong)產生自(zi)感電(dian)(dian)(dian)(dian)(dian)動(dong)勢，自(zi)感電(dian)(dian)(dian)(dian)(dian)動(dong)勢阻礙線(xian)圈中(zhong)的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)變化，這(zhe)時鎮(zhen)流(liu)器起降壓(ya)(ya)限(xian)流(liu)的(de)(de)作用，使(shi)電(dian)(dian)(dian)(dian)(dian)流(liu)穩(wen)(wen)定在燈(deng)管的(de)(de)額(e)定電(dian)(dian)(dian)(dian)(dian)流(liu)范圍(wei)內，燈(deng)管兩(liang)端電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)也(ye)穩(wen)(wen)定在額(e)定工作電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)范圍(wei)內。由(you)于(yu)(yu)這(zhe)個電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)低(di)于(yu)(yu)啟(qi)輝器的(de)(de)電(dian)(dian)(dian)(dian)(dian)離(li)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，所以并聯在兩(liang)端的(de)(de)啟(qi)輝器也(ye)就不再起作用了。

LED日光燈與普通日光燈是一樣的嗎

1、普通日光燈：日光燈兩端各有(you)一燈絲，燈管內(nei)充(chong)有(you)微量的(de)氬(ya)和稀薄(bo)的(de)汞蒸氣(qi)，燈管內(nei)壁上涂有(you)螢光粉，兩個(ge)燈絲之間的(de)氣(qi)體導電時(shi)發出紫外線，使螢光粉發出柔和的(de)可(ke)見光。

普(pu)通(tong)日光(guang)燈工作特(te)點：燈管(guan)開始點燃時(shi)(shi)需要一個高電壓，正常(chang)發光(guang)時(shi)(shi)只允許通(tong)過(guo)不大的(de)電流，這時(shi)(shi)燈管(guan)兩端的(de)電壓低于電源電壓。

2、LED日(ri)光(guang)燈(deng)(deng)管：led日(ri)光(guang)燈(deng)(deng)以質優、耐用(yong)、節(jie)能為主要特點(dian)，投(tou)射角度(du)調節(jie)范圍大，15W的亮度(du)相當(dang)于普通40W日(ri)光(guang)燈(deng)(deng)。抗高溫、防(fang)潮防(fang)水、防(fang)漏電。使用(yong)電壓(ya)有:110V、220V可(ke)選，外(wai)罩可(ke)選玻璃或(huo)PC材質。燈(deng)(deng)頭(tou)與普通日(ri)光(guang)燈(deng)(deng)一(yi)樣。

LED日(ri)(ri)光(guang)(guang)燈(deng)(deng)(deng)(deng)管采用最新的(de)(de)(de)LED光(guang)(guang)源技(ji)術，數位化(hua)外觀設計(ji)，節(jie)電高達70%以上，12W的(de)(de)(de)LED日(ri)(ri)光(guang)(guang)燈(deng)(deng)(deng)(deng)光(guang)(guang)強(qiang)相(xiang)當于40W的(de)(de)(de)日(ri)(ri)光(guang)(guang)燈(deng)(deng)(deng)(deng)管(用于鎮(zhen)流器和啟輝(hui)器，36W的(de)(de)(de)日(ri)(ri)光(guang)(guang)燈(deng)(deng)(deng)(deng)真(zhen)正(zheng)的(de)(de)(de)耗電量為(wei)42W至44W)。LED日(ri)(ri)光(guang)(guang)燈(deng)(deng)(deng)(deng)壽(shou)命為(wei)普通燈(deng)(deng)(deng)(deng)管的(de)(de)(de)10倍以上，幾乎免維護(hu)，無須經常更換燈(deng)(deng)(deng)(deng)管、鎮(zhen)流器、啟輝(hui)器。綠色環(huan)保的(de)(de)(de)半導體(ti)電光(guang)(guang)源，光(guang)(guang)線柔和，光(guang)(guang)譜純，有(you)利于使(shi)用者(zhe)的(de)(de)(de)視力保護(hu)及身體(ti)健(jian)康。6000K的(de)(de)(de)冷光(guang)(guang)源給人視覺上清涼的(de)(de)(de)感受，人性化(hua)的(de)(de)(de)照(zhao)度差異(yi)設計(ji)，更有(you)助(zhu)于集(ji)中精神，提(ti)高效率。

3、LED日光燈管的優(you)點：

1.節能，16W相當(dang)于(yu)普通日光燈40W的(de)亮度，節能率達到60%以上。

2.壽命長，正(zheng)常可以(yi)用50000H小(xiao)時，質保(bao)3年。

3.適用性(xing)好(hao)，因(yin)單(dan)顆LED的體積小，可(ke)以做成任何形狀(zhuang)。

4.回(hui)應(ying)時(shi)(shi)(shi)間短(duan)，是ns(納(na)秒)級別的回(hui)應(ying)時(shi)(shi)(shi)間，而(er)普(pu)通(tong)燈具是ms(毫(hao)秒)級別的回(hui)應(ying)時(shi)(shi)(shi)間。

5.環保，無有害金屬，廢(fei)棄物容易回收。

6.色彩(cai)絢麗(li)，發光色彩(cai)純正，光譜范(fan)圍(wei)窄，并能通(tong)過(guo)紅(hong)綠藍三基(ji)色混色成(cheng)七彩(cai)或者白光。

LED日光燈管使用注意事項

LED日光燈管一定要做好防水措施，避免(mian)潮濕空氣進(jin)入難以排出，長期腐蝕里面(mian)的(de)電(dian)(dian)氣元件，還可能造成短路，損壞里面(mian)的(de)電(dian)(dian)氣元件，或會(hui)引起火災。
