在廣告宣傳遍布大街小巷的今天，LED燈成為平面廣告重要的媒介。作為LED燈主要的成分，LED控制器充當著控(kong)制LED燈的(de)(de)角色(se)，可以按照使用者(zhe)的(de)(de)興趣和需(xu)求(qiu)，隨意自(zi)由地設(she)定LED燈光效果，非常智能。那么(me)(me)，LED控(kong)制器分為什(shen)(shen)么(me)(me)種(zhong)類(lei)?每一種(zhong)LED控(kong)制器有(you)什(shen)(shen)么(me)(me)優缺點(dian)?每一種(zhong)LED控(kong)制器有(you)什(shen)(shen)么(me)(me)特點(dian)?LED控(kong)制器有(you)什(shen)(shen)么(me)(me)注(zhu)意事項(xiang)?下列上海歐切斯實業有(you)限公司(si)帶您領略各種(zhong)類(lei)型(xing)的(de)(de)LED控(kong)制器的(de)(de)魅(mei)力。

　　LED控制(zhi)器(qi)分為低壓(ya)型(xing)LED產品(pin)(pin)大功率(lv)控制(zhi)器(qi)、高壓(ya)型(xing)LED產品(pin)(pin)控制(zhi)器(qi)和低壓(ya)型(xing)LED產品(pin)(pin)串行控制(zhi)器(qi)三種(zhong)類型(xing)。下(xia)面分別詳(xiang)細地介紹每(mei)一種(zhong)LED控制(zhi)器(qi)。

　　低(di)(di)(di)(di)壓(ya)(ya)型LED產(chan)(chan)品(pin)(pin)大(da)(da)功(gong)(gong)率(lv)控(kong)(kong)(kong)制(zhi)器(qi)通常(chang)設(she)計(ji)的(de)電(dian)(dian)壓(ya)(ya)范圍為(wei)12V到(dao)36V，一個LED燈(deng)由多(duo)個回路的(de) LED燈(deng)組成(cheng)。低(di)(di)(di)(di)壓(ya)(ya)型LED產(chan)(chan)品(pin)(pin)大(da)(da)功(gong)(gong)率(lv)控(kong)(kong)(kong)制(zhi)器(qi)因為(wei)低(di)(di)(di)(di)壓(ya)(ya)，所(suo)以(yi)設(she)計(ji)比較容易，結構相(xiang)對簡單。但是(shi)當低(di)(di)(di)(di)壓(ya)(ya)型LED產(chan)(chan)品(pin)(pin)大(da)(da)功(gong)(gong)率(lv)控(kong)(kong)(kong)制(zhi)器(qi)規模(mo)大(da)(da)時電(dian)(dian)流也(ye)會相(xiang)應地(di)很大(da)(da)，這時就(jiu)需要配置相(xiang)應的(de)低(di)(di)(di)(di)壓(ya)(ya)開(kai)關電(dian)(dian)源(yuan)，且(qie)低(di)(di)(di)(di)壓(ya)(ya)不能完(wan)成(cheng)遠距離輸(shu)電(dian)(dian)的(de)任(ren)務，所(suo)以(yi)低(di)(di)(di)(di)壓(ya)(ya)型LED產(chan)(chan)品(pin)(pin)大(da)(da)功(gong)(gong)率(lv)控(kong)(kong)(kong)制(zhi)器(qi)幾乎是(shi)用(yong)于一些體積不太大(da)(da)的(de)產(chan)(chan)品(pin)(pin)上，如常(chang)見的(de)招牌文字、小圖案(an)擺飾等(deng)。另外，LED一定(ding)為(wei)共陽極(ji)(ji)連接法，LED控(kong)(kong)(kong)制(zhi)器(qi)控(kong)(kong)(kong)制(zhi)陰極(ji)(ji)，并且(qie)LED控(kong)(kong)(kong)制(zhi)器(qi)不包含(han)低(di)(di)(di)(di)壓(ya)(ya)電(dian)(dian)源(yuan)。

　　高壓(ya)(ya)(ya)型LED產(chan)品(pin)(pin)控(kong)制器(qi)通(tong)(tong)常(chang)設計(ji)的(de)電(dian)(dian)壓(ya)(ya)(ya)范圍為交流(liu)(liu)或者直(zhi)流(liu)(liu)220V電(dian)(dian)壓(ya)(ya)(ya)。其中高壓(ya)(ya)(ya)型LED產(chan)品(pin)(pin)控(kong)制器(qi)的(de)限流(liu)(liu)方(fang)(fang)式大致(zhi)分為兩種。目前(qian)被廣泛運用的(de)穩定可靠方(fang)(fang)法是電(dian)(dian)阻(zu)限流(liu)(liu)，特點(dian)是電(dian)(dian)阻(zu)功耗比較(jiao)大，一(yi)(yi)般在每(mei)四個LED燈之(zhi)間串(chuan)(chuan)接(jie)一(yi)(yi)個0.25W的(de)金屬模(mo)電(dian)(dian)阻(zu)，使其可以(yi)均勻分布散熱。而第二種方(fang)(fang)法——電(dian)(dian)阻(zu)電(dian)(dian)容(rong)串(chuan)(chuan)聯限流(liu)(liu)，由于大多(duo)數的(de)電(dian)(dian)壓(ya)(ya)(ya)降(jiang)在了電(dian)(dian)容(rong)上，因此(ci)這種LED控(kong)制器(qi)電(dian)(dian)阻(zu)功耗小，只能夠適用于一(yi)(yi)些穩定的(de)長亮狀態(tai)，不能進行閃動電(dian)(dian)容(rong)儲能，否則會導致(zhi)電(dian)(dian)壓(ya)(ya)(ya)加倍(bei)，而造成損壞。低壓(ya)(ya)(ya)型LED產(chan)品(pin)(pin)串(chuan)(chuan)行控(kong)制器(qi)的(de)控(kong)制路數非常(chang)多(duo)。它是通(tong)(tong)過串(chuan)(chuan)行信號(hao)傳(chuan)輸(shu)達到控(kong)制。
