一：看亮度，就是通常大家所說的你的燈珠能達到多少LM(流明)，LM(流明)是衡量燈珠亮度的單位 </p> <p> <br /> </p> <p> 二：看發(fā)光是否均勻顏色是否一致，質(zhì)量的好的燈珠發(fā)光很均勻，顏色一致，黑龍江供應(yīng)安燈看板什么價格。品質(zhì)差的燈珠會出現(xiàn)一顆燈珠亮度亮，一顆燈珠暗的現(xiàn)象，發(fā)光顏色亂七八糟不統(tǒng)一，會有明顯的暗區(qū)。 </p> <p> <br /> </p> <p> 三：看芯片和芯片大小，芯片又是燈珠質(zhì)量好壞的決定因素，一般情況下芯片越大穩(wěn)定性就越強，亮度就越高，散熱就越好。 </p> <p> <br /> </p> <p> 四：看膠水和熒光粉，一般好的產(chǎn)品都會用進口膠水，封裝好了的燈珠用手按不變形，質(zhì)量低廉的膠水一按就會出現(xiàn)變形甚至開裂等現(xiàn)象，黑龍江供應(yīng)安燈看板什么價格。 </p> <p> <br /> </p> <p> 五：看支架，一般情況支架為鍍銀紅銅支架，鍍銀紅銅支架的好處就是散熱快，可以更好的給燈珠散熱，電阻小。市場上有些商家會用陶瓷支架來代替鍍銀紅銅支架，陶瓷支架導(dǎo)熱性能 </p> <p> <br /> </p> <p> 六：看封裝工藝，質(zhì)量好的LED燈珠顏色均勻，膠體一致性好。這就離不開好的機器設(shè)備，生產(chǎn)機器設(shè)備是很關(guān)鍵的一個因素，好的設(shè)備可以保證產(chǎn)品在各個程序上的穩(wěn)定性和一致性，保障產(chǎn)品的良品率。 </p> <p> <br /> </p> <p> 其實**重要的，還是看燈珠的芯片，黑龍江供應(yīng)安燈看板什么價格，芯片直接決定了顯色、亮度、**減程度。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

LED顯示屏主要的組成部件是：單元板、電源、控制卡、連線單元板背面、單元板正面、開關(guān)電源和LED條屏控制卡 </p> <p> LED屏條主要組成部件 </p> <p> <span style="display:none;"></span>單元板 </p> <p> 單元板是LED的顯示**部件之一，單元板的好壞，直接影響到顯示效果的。單元板由LED模塊，驅(qū)動芯片和PCB電路板組成。LED模塊，其實是由很多個LED發(fā)光點用樹脂或者塑料封裝起來點陣。 </p> <p> 驅(qū)動芯片主要是74HC595 74HC245/244 74HC1384953。 </p> <p> 戶內(nèi)條屏常用的單元板規(guī)格有： </p> <p> 參數(shù)：D=3.75;點距4.75mm 64點寬x16點高，1/16掃戶內(nèi)亮度。單紅/紅綠雙色 </p> <p> <span style="display:none;"></span> </p> <p> 發(fā)光直徑：指的是發(fā)光點的直徑D=3.75mm </p> <p> 發(fā)光點距離 4.75mm ----根據(jù)觀看者的距離選擇，戶內(nèi)一般選擇4.75 </p> <p> 單元板大?。?4x16---**常用的單元板，**容易買到，價格也低價。 </p> <p> 1/16掃：單元板的控制方式。 </p> <p> 戶內(nèi)亮度：指LED發(fā)光點的亮度，戶內(nèi)亮度適合白天需要靠日光燈照明的環(huán)境。 </p> <p> <br /> </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="黑龍江供應(yīng)安燈看板什么價格"

一、根據(jù)應(yīng)用場合，逐點校正系統(tǒng)分為兩種： </p> <p> <br /> </p> <p> 1、單個LED箱體逐點校正，在生產(chǎn)線上進行逐箱校正，保證出廠的每個箱體達到高度的均勻性； </p> <p> 2、現(xiàn)場大屏逐點校正，在LED全彩大屏幕顯示現(xiàn)場選擇合適的觀看地點進行現(xiàn)場校正，保證顯示屏在現(xiàn)場觀測位置達到高度的均勻性； </p> <p> <br /> </p> <p> 二、逐點校正又分為色度校正和亮度校正。 </p> <p> <br /> </p> <p> 1.亮度校正是LED發(fā)光強度的校正。在目前，由于某些校正儀器缺乏良好的色彩分辨能力，并不能精確測量到這種光譜上的差異，因此只能進行發(fā)光強度上的測量而不能精確測量其色度偏差。 </p> <p> 2.色度校正是指那些具備色彩分辨能力強的測光儀器的校正方式，它能夠較為準確的測量得到LED的亮度、色度值。 </p> <p> <br /> </p> <p> 因此，使用了不同批次但主波長相同的尾檔LED屏幕，就有必要進行亮度和色度的校正。既能保證整個LED電子顯示屏畫面的亮度一致，又可以正常呈現(xiàn)畫面的色彩顯示效果。尾檔產(chǎn)品一般價格要比市場的大檔產(chǎn)品有價格優(yōu)勢，通過逐點校正技術(shù)，這些不同批次的尾檔又可以發(fā)揮正常功能，提高了LED顯示屏產(chǎn)品的使用價值，也為客戶節(jié)省了大筆的成本開支。
