一、led驅動電源通用嗎
led驅動電源是不通用的。led燈采用的燈珠很多種,燈珠數量不一樣因此燈的功率大小不相同。就算是同樣的燈珠,其連接方式也是多種多樣,燈的額定電壓和額定電流勢必也不一致,因此不可能所有的燈用同一個led驅動器。但有些燈能(neng)夠用同(tong)一個(ge)驅動(dong)器還是有可能(neng)的(de),只(zhi)要led驅動(dong)電(dian)(dian)源的(de)功率輸(shu)出(chu)電(dian)(dian)壓(ya)和輸(shu)出(chu)電(dian)(dian)流都一致就(jiu)可以了。
二、led燈驅動電源怎么配
每款LED燈的驅動器都是搭配好的,如果驅動器出現了故障,LED燈肯定是無法正常使用的,此(ci)時(shi)我們可(ke)以在五(wu)金市場購買新(xin)的驅(qu)動器更換。
LED燈電(dian)源在(zai)(zai)選擇上主(zhu)要(yao)從電(dian)源的輸(shu)出電(dian)壓、輸(shu)出電(dian)流(liu)、以及所對應在(zai)(zai)功率瓦數(shu)等方面來(lai)考慮。
LED電(dian)(dian)(dian)(dian)(dian)源一般有恒(heng)流源輸(shu)(shu)(shu)出的(de)(de)(de)(de)(de)(de)、也(ye)有恒(heng)壓(ya)源輸(shu)(shu)(shu)出的(de)(de)(de)(de)(de)(de)兩種(zhong),先(xian)從恒(heng)流源輸(shu)(shu)(shu)出的(de)(de)(de)(de)(de)(de)LED電(dian)(dian)(dian)(dian)(dian)源來(lai)說,我們(men)主要考慮(lv)它(ta)的(de)(de)(de)(de)(de)(de)輸(shu)(shu)(shu)出電(dian)(dian)(dian)(dian)(dian)壓(ya),對于輸(shu)(shu)(shu)出相同電(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)(de)(de)(de)LED電(dian)(dian)(dian)(dian)(dian)源驅動器它(ta)的(de)(de)(de)(de)(de)(de)輸(shu)(shu)(shu)出電(dian)(dian)(dian)(dian)(dian)壓(ya)也(ye)是不(bu)一樣的(de)(de)(de)(de)(de)(de),因此(ci)在選恒(heng)流LED電(dian)(dian)(dian)(dian)(dian)源時要與(yu)LED燈的(de)(de)(de)(de)(de)(de)工作電(dian)(dian)(dian)(dian)(dian)壓(ya)相一致,比如對于額(e)定電(dian)(dian)(dian)(dian)(dian)流在200毫安到(dao)(dao)300毫安的(de)(de)(de)(de)(de)(de)恒(heng)流LED電(dian)(dian)(dian)(dian)(dian)源,它(ta)的(de)(de)(de)(de)(de)(de)輸(shu)(shu)(shu)出電(dian)(dian)(dian)(dian)(dian)壓(ya)有9V到(dao)(dao)13V之間范(fan)(fan)(fan)圍(wei)的(de)(de)(de)(de)(de)(de)、10V到(dao)(dao)25V之間范(fan)(fan)(fan)圍(wei)的(de)(de)(de)(de)(de)(de)、24V到(dao)(dao)42V之間范(fan)(fan)(fan)圍(wei)的(de)(de)(de)(de)(de)(de)、45V到(dao)(dao)63V之間范(fan)(fan)(fan)圍(wei)的(de)(de)(de)(de)(de)(de)等(deng)等(deng),因此(ci)我們(men)選擇這種(zhong)電(dian)(dian)(dian)(dian)(dian)源就要考慮(lv)它(ta)的(de)(de)(de)(de)(de)(de)輸(shu)(shu)(shu)出電(dian)(dian)(dian)(dian)(dian)壓(ya)范(fan)(fan)(fan)圍(wei)了。
同樣(yang),對于恒(heng)壓(ya)源LED電(dian)(dian)源驅動器來說(shuo),在(zai)相同的(de)(de)輸出(chu)電(dian)(dian)壓(ya)下,它(ta)的(de)(de)輸出(chu)電(dian)(dian)流也是不一(yi)樣(yang)的(de)(de),因此(ci)我們(men)選(xuan)擇LED電(dian)(dian)源時(shi)就需要(yao)根據不同類型的(de)(de)LED電(dian)(dian)源考慮到它(ta)的(de)(de)輸出(chu)電(dian)(dian)壓(ya)或者(zhe)電(dian)(dian)流了。另(ling)外還要(yao)考慮到LED電(dian)(dian)源的(de)(de)功(gong)率(lv)范圍(wei),如果(guo)功(gong)率(lv)范圍(wei)選(xuan)錯(cuo)的(de)(de)話會(hui)燒壞LED燈珠,或者(zhe)造成(cheng)LED燈頻(pin)閃(shan)的(de)(de)現象。
對(dui)于簡單的(de)(de)LED燈(deng)(deng)來(lai)說,常(chang)常(chang)會通(tong)過簡單的(de)(de)RC阻(zu)容降(jiang)壓(ya)環節(jie)進(jin)行(xing)降(jiang)壓(ya),然后通(tong)過二極管(guan)進(jin)行(xing)整理后再加一個(ge)合適的(de)(de)限流電(dian)阻(zu),就(jiu)可(ke)以(yi)驅動大約(yue)十幾(ji)個(ge)高亮度(du)LED燈(deng)(deng)珠了,這里的(de)(de)燈(deng)(deng)珠可(ke)以(yi)是并聯(lian),也可(ke)以(yi)是串聯(lian)的(de)(de),但(dan)是這個(ge)限流的(de)(de)電(dian)阻(zu)一定要選(xuan)擇好。
led驅動電源的作用(yong)就是把220伏交流電轉換成(cheng)燈所需要的直流電,現在基本上(shang)都(dou)是以(yi)恒流電源為主,不同品牌采用(yong)的方案可(ke)能(neng)不一樣,零配(pei)件也可(ke)能(neng)有差別,但正規廠家的產品還是值得(de)信任(ren)的。
