style="font-size:14px;">1、散熱設(shè)計(jì)</span> </p> <p> <span style="font-size:14px;">LED工作時(shí)會(huì)發(fā)熱，溫度過高會(huì)影響LED的衰減速度和穩(wěn)定性，故PCB板的散熱設(shè)計(jì)、箱體的通風(fēng)散熱設(shè)計(jì)都會(huì)影響LED的表現(xiàn)。</span> </p> <p> <span style="font-size:14px;">2、混燈</span> </p> <p> <span style="font-size:14px;">同一種顏色不同亮度檔的LED需要混燈，或者按照離散規(guī)律設(shè)計(jì)的插燈圖進(jìn)行插燈，以保證整屏每種顏色亮度的一致性。此工序如果出現(xiàn)問題，會(huì)出現(xiàn)大屏幕局部亮度不一致的現(xiàn)象，直接影響LED大屏幕的顯示效果。</span> </p> <p> <span style="font-size:14px;">3、設(shè)計(jì)電流值</span> </p> <p> <span style="font-size:14px;">LED的標(biāo)稱電流為20mA，一般建議其使用電流為不超過標(biāo)稱值的80%，尤其對(duì)于點(diǎn)間距很小的大屏幕，由于散熱條件不佳，還應(yīng)降低電流值。根據(jù)經(jīng)驗(yàn)，由于紅，昆明P3室內(nèi)全彩大屏幕多少錢一平、綠，昆明P3室內(nèi)全彩大屏幕多少錢一平、藍(lán)LED衰減速度的不一致性，有針對(duì)性地降低藍(lán)、綠LED的電流值，昆明P3室內(nèi)全彩大屏幕多少錢一平，以保持大屏幕長時(shí)間使用后白平衡的一致性。</span> 引起LED顯示屏起火問題主要有三大來源。昆明P3室內(nèi)全彩大屏幕多少錢一平</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="昆明P3室內(nèi)全彩大屏幕多少錢一平,全彩"

style="font-size:14px;">1、以較快的速度用布或毛巾吸掉大量的水分,下一步烘干,注意需要斷電操作。</span> </p> <p> <span style="font-size:14px;">2、烘干屏體之后繼續(xù)通電老化,具體的操作步驟如下：</span> </p> <p> <span style="font-size:14px;">分階段操作：屏幕全白亮度為10%,通電老化時(shí)間為8-12個(gè)小時(shí)。</span> </p> <p> <span style="font-size:14px;">全白亮度為30%,時(shí)間為12小時(shí)</span> </p> <p> <span style="font-size:14px;">全白亮度為60%,時(shí)間為12-24小時(shí)</span> </p> <p> <span style="font-size:14px;">全白亮度為80%,時(shí)間為12-24小時(shí)</span> </p> <p> <span style="font-size:14px;">全白亮度為100,時(shí)間為8-12小時(shí)</span> </p> <p> <span style="font-size:14px;">3、完成以上步驟基本上就沒什么問題了。但是在操作的過程中需要注意以下幾點(diǎn)：</span> </p> <p> <span style="font-size:14px;">a、在LED電子屏屏體進(jìn)水時(shí)應(yīng)及時(shí)做出對(duì)應(yīng)措施,不要拖延時(shí)間。</span> </p> <p> <span style="font-size:14px;">b、對(duì)進(jìn)水的屏體進(jìn)行快速烘干。</span> </p> <p> <span style="font-size:14px;">c、不要將已進(jìn)水的屏體放入航空箱,可能會(huì)導(dǎo)致LED顯示屏燈珠受損。</span> </p> <p> <span style="font-size:14px;">d、注意航空箱是否進(jìn)水。</span> </p> <p> <span style="font-size:14px;">e、進(jìn)水后的屏體如果處理的不及時(shí)可能多少會(huì)影響到屏體的穩(wěn)定性,通電老化過程中可能會(huì)發(fā)現(xiàn)死燈現(xiàn)象。</span> </p> <p> <span style="font-size:14px;">f、進(jìn)水的全彩LED顯示屏屏體如果在航空箱里面超過72小時(shí)以上,基本無修復(fù)的價(jià)值,請(qǐng)謹(jǐn)慎處理。</span> 昆明室內(nèi)P5全彩大屏價(jià)格LED顯示屏面積越大，使用的電量越大，發(fā)熱越明顯。</p><div style="width:100%;text-align:
