LED燈中電容如何使用

電(dian)(dian)(dian)(dian)(dian)容的(de)基本作用就(jiu)是存(cun)儲電(dian)(dian)(dian)(dian)(dian)荷(he)。對于智能充(chong)電(dian)(dian)(dian)(dian)(dian)式電(dian)(dian)(dian)(dian)(dian)路(lu)系統，電(dian)(dian)(dian)(dian)(dian)容建立了反饋電(dian)(dian)(dian)(dian)(dian)路(lu)，那么(me)電(dian)(dian)(dian)(dian)(dian)容的(de)實際電(dian)(dian)(dian)(dian)(dian)荷(he)存(cun)儲量會讓(rang)電(dian)(dian)(dian)(dian)(dian)路(lu)自動調整(zheng)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流。而充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流的(de)高低會決(jue)定LED指示(shi)燈(deng)的(de)顏色顯(xian)示(shi)，紅(hong)燈(deng)、紅(hong)綠雙色、綠燈(deng)

led燈上有兩個電容有什么用

補償電(dian)容(rong)的(de)作用(yong)無非就是在(zai)三(san)極管(guan)工作時(shi)提供部(bu)分(fen)電(dian)流(liu)。 在(zai)三(san)極管(guan)截(jie)止時(shi)充電(dian)，另一方面它對電(dian)路(lu)(lu)的(de)振蕩開始工作時(shi)提供初始激勵作用(yong)，在(zai)電(dian)路(lu)(lu)工作時(shi)提高振蕩電(dian)路(lu)(lu)穩定性(xing)。萊垍頭(tou)條

led串電容的作用

LED驅動電源中電容的作用

LED驅動電(dian)(dian)源中的(de)電(dian)(dian)容(rong)，一(yi)般會在兩個地(di)方(fang)出現(xian)。一(yi)個是220V電(dian)(dian)壓(ya)(ya)經(jing)(jing)過(guo)(guo)整流(liu)(liu)后，另外一(yi)個是經(jing)(jing)過(guo)(guo)變(bian)壓(ya)(ya)器(qi)(qi)變(bian)壓(ya)(ya)之后的(de)輸出端。這(zhe)兩個地(di)方(fang)的(de)電(dian)(dian)容(rong)通常使用電(dian)(dian)解電(dian)(dian)容(rong)，其(qi)主要(yao)作用是濾波(bo)。無(wu)論是220V經(jing)(jing)過(guo)(guo)整流(liu)(liu)，還是變(bian)壓(ya)(ya)器(qi)(qi)輸出后，都是交流(liu)(liu)電(dian)(dian)經(jing)(jing)過(guo)(guo)整流(liu)(liu)之后的(de)，尤其(qi)是經(jing)(jing)過(guo)(guo)變(bian)壓(ya)(ya)器(qi)(qi)輸出之后的(de)為高頻的(de)脈動直流(liu)(liu)。就需要(yao)通過(guo)(guo)電(dian)(dian)容(rong)的(de)儲(chu)能作用進行濾波(bo)，才能將脈動的(de)直流(liu)(liu)電(dian)(dian)變(bian)得(de)相對平滑。

led燈驅動里耐壓電容的作用是什么

LED驅動(dong)電(dian)源中的(de)電(dian)容(rong)一般(ban)出(chu)現(xian)在(zai)(zai)兩個地方，一個是(shi)(shi)220V電(dian)壓經過整流后，一個是(shi)(shi)經過變壓器(qi)變壓之(zhi)后的(de)輸出(chu)端。在(zai)(zai)這兩個地方的(de)電(dian)容(rong)一般(ban)是(shi)(shi)使(shi)用電(dian)解電(dian)容(rong)，主要作用是(shi)(shi)濾(lv)波。

LED驅動電(dian)(dian)源中電(dian)(dian)容的作用

無(wu)論(lun)是(shi)220V經過整流，還是(shi)變壓(ya)器(qi)輸出后，均(jun)是(shi)交(jiao)流電經過整流后的(de)，尤(you)其是(shi)經過變壓(ya)器(qi)輸出后的(de)為高頻的(de)脈(mo)動直(zhi)流。

所以，需要通(tong)過電(dian)容的儲能作用(yong)進行濾波，才可以將脈(mo)動(dong)的直流電(dian)變得相對平滑。

LED燈為什么要加電容

接(jie)上電(dian)(dian)(dian)(dian)容(rong)就不會給濾波電(dian)(dian)(dian)(dian)容(rong)充電(dian)(dian)(dian)(dian)，燈(deng)沒(mei)電(dian)(dian)(dian)(dian)也就不亮了。問題出在LED燈(deng)具配套的恒流源（俗稱(cheng)驅(qu)動）是(shi)開關(guan)電(dian)(dian)(dian)(dian)源架(jia)構(gou)，這(zhe)種(zhong)架(jia)構(gou)交流市電(dian)(dian)(dian)(dian)整流后有(you)個濾波大容(rong)量電(dian)(dian)(dian)(dian)容(rong)，關(guan)斷開關(guan)后電(dian)(dian)(dian)(dian)路(lu)失電(dian)(dian)(dian)(dian)，燈(deng)熄滅。

從分(fen)布電容(rong)漏(lou)過來的極(ji)微小的電流很容(rong)易(yi)通(tong)過這個(ge)后(hou)接(jie)的電容(rong)返回電網。

電(dian)(dian)容本(ben)質(zhi)上是(shi)并聯(lian)在燈(deng)具恒流源輸入(ru)端2交流接線之間(jian)，由于電(dian)(dian)容更(geng)容易通過(guo)(guo)交流電(dian)(dian)，所以從分布電(dian)(dian)容漏過(guo)(guo)來(lai)的(de)(de)極微小電(dian)(dian)流的(de)(de)絕大(da)部(bu)分，都(dou)通過(guo)(guo)這個并聯(lian)的(de)(de)電(dian)(dian)容返(fan)回電(dian)(dian)網了。

接上電容就基(ji)本(ben)斷絕了給(gei)濾波電容充電的環節，當然也就不(bu)閃了。擴展資料：返回電網(wang)的電流并未做(zuo)功，所以不(bu)會增加耗電。

如果一定要精確計(ji)算，理論上(shang)這(zhe)么做比原來(lai)關斷燈具(ju)時的狀態還要省電(dian)（因(yin)電(dian)源(yuan)布線(xian)原來(lai)就存(cun)在(zai)的分布電(dian)容沒變，但關斷開關后漏過(guo)來(lai)的極微小電(dian)流的絕大(da)部(bu)分，不(bu)是流過(guo)燈具(ju)產生耗電(dian)，而是通過(guo)并聯(lian)的電(dian)容返回電(dian)網(wang)了）。

其(qi)實，無論開關通(tong)與斷，分布電(dian)容都在，只是開關接通(tong)時，將分布電(dian)容短路(lu)了，使(shi)其(qi)在電(dian)路(lu)中不(bu)起作(zuo)用。
