led變壓器怎么改電流

變壓器是怎么調整電流的

1??我繞制過好些變(bian)(bian)壓(ya)器，要想變(bian)(bian)壓(ya)器輸(shu)出電(dian)流大(da)，決定在變(bian)(bian)壓(ya)器的體積和(he)線徑，也就(jiu)是你要選多大(da)功率(lv)的變(bian)(bian)壓(ya)器，是50W，500W，還是1000W，你要輸(shu)出的總功率(lv)只能打個(ge)八折計算。

2??你想提高輸出(chu)電壓，只有在變壓器窗口大小上來計算線徑，匝(za)數繞得越多(duo)電壓越高，反(fan)比電流越小。

3??我繞變(bian)壓(ya)器利用(yong)匝數控制電(dian)壓(ya)，我用(yong)增(zeng)加(jia)線(xian)徑(jing)減少匝數改(gai)變(bian)電(dian)流，比如(ru)變(bian)壓(ya)器要(yao)繞幾(ji)匝用(yong)于LED指示燈，只(zhi)要(yao)比發(fa)(fa)絲粗的漆包(bao)線(xian)就(jiu)能做到。用(yong)變(bian)壓(ya)器調整電(dian)流只(zhi)要(yao)改(gai)變(bian)漆包(bao)線(xian)直徑(jing)就(jiu)可任(ren)意調節(jie)輸出(chu)電(dian)流，在(zai)實驗(yan)中(zhong)，大變(bian)壓(ya)器輸出(chu)功率(lv)(lv)足夠，可你(ni)用(yong)了小線(xian)徑(jing)漆包(bao)線(xian)，再去用(yong)大功率(lv)(lv)電(dian)泡（比如(ru)汽(qi)車燈泡12V60W），一通電(dian)12V電(dian)壓(ya)就(jiu)下(xia)降不到10V使燈泡變(bian)暗，線(xian)發(fa)(fa)熱，如(ru)果你(ni)改(gai)用(yong)12V15W的就(jiu)不降壓(ya)，不超載不會降壓(ya)也不發(fa)(fa)熱，強調功率(lv)(lv)要(yao)相配。

4??由此你想用(yong)變壓器(qi)限(xian)流的關(guan)鍵：變壓器(qi)功(gong)率大于負載功(gong)率，其次是用(yong)小線徑。

5??還有一種辦(ban)法是不(bu)怕你變(bian)壓器功(gong)率(lv)大，但只(zhi)要你把輸(shu)出電(dian)壓控制低于用電(dian)器標稱電(dian)壓10％，比如12V的用電(dian)器，你把變(bian)壓器輸(shu)出降(jiang)低為11V，或者(zhe)串聯一只(zhi)大功(gong)率(lv)二極管降(jiang)去0．7V也行，這樣一來電(dian)流(liu)自動下降(jiang)，這叫負載固定(ding)，降(jiang)低電(dian)壓，電(dian)流(liu)就減(jian)小。

6??現在電(dian)(dian)(dian)(dian)(dian)瓶(ping)(ping)(ping)車充電(dian)(dian)(dian)(dian)(dian)器都是開關電(dian)(dian)(dian)(dian)(dian)源，設計的(de)輸出(chu)為12V電(dian)(dian)(dian)(dian)(dian)瓶(ping)(ping)(ping)的(de)1．2倍為14．4V，電(dian)(dian)(dian)(dian)(dian)瓶(ping)(ping)(ping)在充電(dian)(dian)(dian)(dian)(dian)中，當充滿了(le)電(dian)(dian)(dian)(dian)(dian)壓上(shang)升(sheng)電(dian)(dian)(dian)(dian)(dian)流(liu)就(jiu)減小(xiao)，電(dian)(dian)(dian)(dian)(dian)瓶(ping)(ping)(ping)虛壓與(yu)充電(dian)(dian)(dian)(dian)(dian)器持平，即使不(bu)拔(ba)插子(zi)電(dian)(dian)(dian)(dian)(dian)瓶(ping)(ping)(ping)還不(bu)會過(guo)充。我用那種電(dian)(dian)(dian)(dian)(dian)焊機(ji)式的(de)大變壓器也充過(guo)電(dian)(dian)(dian)(dian)(dian)瓶(ping)(ping)(ping)，用14V充，幾分(fen)鐘電(dian)(dian)(dian)(dian)(dian)瓶(ping)(ping)(ping)沸騰燙(tang)手，電(dian)(dian)(dian)(dian)(dian)流(liu)表顯示十(shi)幾安培電(dian)(dian)(dian)(dian)(dian)流(liu)，我馬(ma)上(shang)改用12V充，一切都變了(le)，電(dian)(dian)(dian)(dian)(dian)流(liu)只在3安培，充到沒有電(dian)(dian)(dian)(dian)(dian)流(liu)讀數，也完成了(le)，電(dian)(dian)(dian)(dian)(dian)瓶(ping)(ping)(ping)也量到13．5V。

所以(yi)，上面這兩種方法(fa)可(ke)以(yi)使變(bian)壓(ya)器限流你試試，很(hen)簡單

led燈珠怎么改裝直流

led燈珠是(shi)半導體(ti)發光元件，其本身就是(shi)有"整流(liu)(liu)"(只用(yong)交(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)半周)性質(zhi)的，它有個正向(xiang)(xiang)導通，反向(xiang)(xiang)截止的特性，不(bu)用(yong)把(ba)它改裝成"直(zhi)流(liu)(liu)"。由(you)led燈珠組(zu)成的燈板(ban)是(shi)使(shi)(shi)用(yong)直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)，它是(shi)由(you)配(pei)套的驅動器提供直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)。驅動器是(shi)把(ba)輸入的220V交(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)變換成低壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)的直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)源，要把(ba)它改用(yong)直(zhi)流(liu)(liu)供電(dian)(dian)(dian)(dian)(電(dian)(dian)(dian)(dian)池、電(dian)(dian)(dian)(dian)瓶、適(shi)配(pei)器等(deng))，只須不(bu)使(shi)(shi)用(yong)驅動器改為燈板(ban)直(zhi)流(liu)(liu)供電(dian)(dian)(dian)(dian)。

220vled燈如何改低壓變壓器

想將(jiang)(jiang)交流(liu)220V的(de)(de)(de)LED軌(gui)(gui)道(dao)燈改成(cheng)低(di)壓(ya)12V的(de)(de)(de),簡單(dan)的(de)(de)(de)方法就是(shi)將(jiang)(jiang)軌(gui)(gui)道(dao)燈內(nei)部的(de)(de)(de)高(gao)壓(ya)恒流(liu)驅動(dong)(dong)器換成(cheng)低(di)壓(ya)12V的(de)(de)(de)恒流(liu)驅動(dong)(dong)器,若軌(gui)(gui)道(dao)燈是(shi)那種小功率的(de)(de)(de)只有(you)3個串(chuan)聯LED燈珠(zhu)構成(cheng)的(de)(de)(de)軌(gui)(gui)道(dao)燈,直(zhi)接將(jiang)(jiang)其燈珠(zhu)與12V的(de)(de)(de)恒流(liu)驅動(dong)(dong)器連接即可工作(zuo)。

希望給你帶來幫助。

燈帶變壓器怎么改裝成逆變器

LED電(dian)子(zi)變壓(ya)器（是恒流源）功率(lv)很(hen)小，沒實用(yong)價值(zhi)。可將直流15-20W的12V節能燈去掉燈管(guan)(guan)后(hou)將原燈管(guan)(guan)電(dian)極串(chuan)個2200-6800P/630V 的電(dian)容，它輸(shu)出電(dian)壓(ya)很(hen)高，也有一定(ding)功率(lv)

之前普通12vG4燈珠常壞想換led節能燈珠連變壓器一起換是選擇220v的好還是12v的配一個恒壓穩流的好

20w12v的和(he)20w220v區別(bie)是(shi)電(dian)(dian)源電(dian)(dian)壓不(bu)一樣，燈(deng)絲(si)電(dian)(dian)阻(zu)也不(bu)一樣，20w12v是(shi)12V供(gong)電(dian)(dian)（交直流(liu)都可以），20w220v是(shi)220V供(gong)電(dian)(dian)（一般就(jiu)是(shi)交流(liu)）。

如果要換成20w220v的，就變(bian)壓器(qi)都可以不要了，直接(jie)接(jie)市(shi)電(dian)(dian)220V就可以，只(zhi)是注意電(dian)(dian)源(yuan)安全。

如果換(huan)成LED，原來的變壓器可以(yi)繼續使用(yong)，但一般要加整流以(yi)及(ji)恒(heng)流驅動電路(lu)，比較麻煩。要么(me)就直接使用(yong)LED廠家(jia)配套電源。

變(bian)壓(ya)(ya)器(qi)好像沒有直流(liu)的燈珠和(he)變(bian)壓(ya)(ya)器(qi)容易(yi)壞，主要是電壓(ya)(ya)不穩、功率(lv)不足以及散熱不良等因素(su)造(zao)成。

以上就是小編(bian)對于led燈珠變壓器改裝(zhuang) 交流電(dian)的(de)(de)led燈珠能(neng)否改用直流電(dian)問(wen)題和相(xiang)關(guan)問(wen)題的(de)(de)解答(da)了，希望對你有(you)用
