style="font-size:14px;">在材料上從大類分上來，可以分為進(jìn)口材料和國產(chǎn)材料。</span> </p> <p> <span style="font-size:14px;">在發(fā)光芯片方面，進(jìn)口的來源是：美國、日本、中國臺灣，還有一些國產(chǎn)芯片。每種發(fā)光芯片都有自己的優(yōu)缺點(diǎn)。長期控制重點(diǎn)技術(shù)的美國和日本芯片，在類似的壟斷中，它們的價格仍然很高。中國臺灣與大陸芯片價格相對便宜，但其性能與美國、日本芯片相比還是有一定差距。</span> </p> <p> <span style="font-size:14px;">如果在重要的場合使用LED戶外顯示屏，推薦使用進(jìn)口材料；除了LED芯片外，影響LED顯示屏價格的主要因素是LED驅(qū)動IC，驅(qū)動芯片是顯示質(zhì)量和壽命的重要因素，全彩LED戶外顯示屏必須采用恒壓恒流驅(qū)動芯片。</span> </p> <p> <br />

style="font-size:14px;">LED顯示屏面積越大，使用的電量越大，發(fā)熱越明顯。加之夏季陽光暴烈，外度溫度高引起散熱難。為解決散熱問題，需從戶外全彩LED顯示屏外型設(shè)計(jì)和內(nèi)部結(jié)構(gòu)進(jìn)行調(diào)整，采用鏤空設(shè)計(jì)，高密度高精度設(shè)計(jì)電路板。內(nèi)部采用微距透空設(shè)計(jì)，不產(chǎn)生積雨，不引起電線短路危險(xiǎn)。不加風(fēng)扇，降低LED電路負(fù)荷，內(nèi)外相結(jié)合達(dá)到高效散熱效果。</span> </p> <p> <span style="font-size:14px;">LED顯示屏屬于大功率電器，易發(fā)生短路。但是真正質(zhì)量過關(guān)的LED顯示屏從線材到結(jié)構(gòu)都杜決短路現(xiàn)象。然而在安裝過程中一點(diǎn)大意和疏忽可能引起意想不到的危險(xiǎn)。為確保安全，需要廠家全程指導(dǎo)安裝，確保接對正負(fù)極、確保電路連接牢固，同時清理戶外全彩LED顯示屏周邊的易燃物。并定期安排專業(yè)技術(shù)人員對LED顯示屏進(jìn)行檢測、檢查。</span> </p><p> <span style="font-size:14px;">LED電子顯示屏照明是有條件的。在PN結(jié)上施加正向電壓會使PN結(jié)本身形成能級（實(shí)際上是一系列能級），電子在該能級上轉(zhuǎn)變并產(chǎn)生光子照射。因此，必須通過施加在PN結(jié)上的電壓來驅(qū)動LED發(fā)光。此外，由于LED是特性敏感半導(dǎo)體器件并且具有負(fù)溫度特性，因此需要在施加過程中穩(wěn)定和保護(hù)工作狀態(tài)，從而產(chǎn)生LED的“驅(qū)動”概念。</span> </p> <p> <span style="font-size:14px;">任何熟悉LED的人都知道LED的前向伏安特性非常陡峭（前向動態(tài)電應(yīng)變非常?。?。向LED供電更加困難。它不能像普通白熾燈那樣直接由電壓源供電。否則，電壓紋波稍微增加，電流增加到LED燃燒的程度。為了穩(wěn)定LED的工作電流并確保LED能夠正?？煽康毓ぷ?，已經(jīng)出現(xiàn)了各種LED驅(qū)動電路。</span>
