大家好今天來(lai)介紹顯(xian)(xian)示(shi)器(qi)led燈(deng)珠電(dian)源(led顯(xian)(xian)示(shi)屏電(dian)源規格)的(de)問(wen)題(ti)，以下是小(xiao)編(bian)對此問(wen)題(ti)的(de)歸納整理，來(lai)看看吧。 文章目錄列表:led電子屏電源型號led顯(xian)示屏電(dian)源規(gui)格：室(shi)內P7.62 244*122 （單(dan)元板(ban)尺寸） 512點（像素點）； 室(shi)內P10 320*160 512點；戶(hu)外P10 160*160 256點； 戶(hu)外P16 256*128 128點 P16 256*256 256點；一般LED燈(deng)規(gui)格區分都用的是(shi)個(ge)大概值(zhi)(zhi)，比如：P10， P8 ，P6等，數值(zhi)(zhi)越(yue)小(xiao)(xiao)單(dan)位內的小(xiao)(xiao)燈(deng)珠越(yue)，亮度和(he)色彩值(zhi)(zhi)也(ye)越(yue)好，也(ye)就(jiu)是(shi)，數值(zhi)(zhi)越(yue)小(xiao)(xiao)效(xiao)果越(yue)好。

顯示器led電源開還是不開顯(xian)示器led電源開啟(qi)。 因為現在的(de)顯(xian)示器(qi)的(de)電(dian)源開關都(dou)是輕觸(chu)是開關，電(dian)源的(de)開啟(qi)是觸(chu)發的(de)，顯(xian)示器(qi)內的(de)微(wei)處理器(qi)如不拔掉(diao)電(dian)源始終是工作(zuo)的(de)，有一些顯(xian)示器(qi)的(de)電(dian)源都(dou)是外置的(de)，一看就明白(bai)了。與待(dai)機相比當然是關了更省電(dian)。 如(ru)果你的(de)顯示(shi)器是和(he)主(zhu)機連在(zai)一起的(de)話（就是說你的(de)顯示(shi)器電(dian)源(yuan)與主(zhu)機相連的(de)）那么就先關閉顯示(shi)器，拔(ba)主(zhu)電(dian)源(yuan)插頭，如(ru)果不是的(de)話。 LED顯示屏電源怎么配置帶多少單元板是怎么計算的。謝謝樓上的(de)(de)(de)都是說(shuo)的(de)(de)(de)P10的(de)(de)(de)，假(jia)如，你不是用(yong)(yong)的(de)(de)(de)P10的(de)(de)(de)呢。我告訴(su)你一個(ge)算板(ban)子功率(lv)的(de)(de)(de)辦(ban)法。一般你接(jie)一個(ge)燈珠0.02A來算，一個(ge)板(ban)上總燈珠*0.02，如果板(ban)是4掃(sao)的(de)(de)(de)帶/4，8掃(sao)的(de)(de)(de)/8，靜態的(de)(de)(de)不除就得出一張板(ban)的(de)(de)(de)功率(lv)再用(yong)(yong)電(dian)源(yuan)的(de)(de)(de)功率(lv)/單張板(ban)的(de)(de)(de)功率(lv)，就是能帶板(ban)的(de)(de)(de)數(shu)量 希望能幫到(dao)你 led燈珠接電腦電源的問題最(zui)多只(zhi)能串三個。因為(wei)LED需要限制電流，所以剩于電壓需要由電阻負擔。假定工(gong)作電壓為(wei)3.2.工(gong)作電流40ma 需要使用60歐的(de)電阻。你可以取(qu)相近標(biao)稱值的(de)62歐，的(de)電阻 以上就是小編對于顯示(shi)器led燈珠電源(led顯示(shi)屏電源規格)問(wen)題和相關問(wen)題的解答了(le)，希(xi)望(wang)對你有用 |
