投光燈是指定被照面上的照度高于周圍環(huán)境的燈具。又稱聚光燈。通常，它能夠瞄準任何方向，并具備不受氣候條件影響的結(jié)構(gòu)。主要用于大面積作業(yè)場礦、建筑物輪廓、體育場、立交橋、紀念碑、公園和花壇等。因此，幾乎所有室外使用的大面積照明燈具都可看作投光燈。投光燈的出射光束角度有寬有窄，變化范圍在0°～180°之間，其中光束特別窄的稱為探照燈。投光燈由光學部件、機械部件和電氣部件3部分組成。光學部件主要是反射器和限制光線投光燈的遮光格片。機械部件主要是外殼，以及固定和調(diào)整光源位置的調(diào)焦機構(gòu)，固定燈具的支架、基座和帶有角度指示的調(diào)整燈具光束投射方向的零件。對絕大部分為密閉式的投光燈，機械部件還有保護玻璃及各種密封圈。根據(jù)使用環(huán)境的需要，有的還帶有金屬網(wǎng)罩。性能良好的投光燈還配有空氣過濾器。電氣部件主要是鎮(zhèn)流器、電容器、觸發(fā)器（根據(jù)光源需要而設(shè)）等。 </p><p style="text-indent:25px">這些要求都為電子行業(yè)的人們所熟悉，關(guān)健是在實際執(zhí)行時是否到位，是否有記錄。據(jù)筆者了解一般的民營企業(yè)，防靜電措施做得并不到位，這就是大多數(shù)企業(yè)查不到接地電阻的測試記錄，即使做了接地電阻測試也是一年一次，或幾年一次，或有問題時檢查一下接地電阻，殊不知接地電阻測試這是一項很重要的工作，每年至少4次（每季度測試一次），一些要求高的地方，每月就要作一次接地電阻測試。土壤電阻會隨著季節(jié)的變化而不同，春夏天雨水多廣泛應用于各種室內(nèi)、戶外顯示屏，分為全色、三色和單色顯示屏，全國有100多個單位在開發(fā)生產(chǎn)。</p><div

style="text-indent:25px">如今，OLED的工作效率比起一-般的LED低得多，比較高的都只是在10%左右。但OLED的生產(chǎn)成本低得多，例如可以用簡單的印制方法將特大的OLED數(shù)組安放在屏幕上，用以制造彩色顯示屏。LED上拉電阻一般LED工作時，加10mA足以使之正常工作，故電阻值為Vo/10mA，Vo即為外加電阻的值，如+5V的電壓下可以使用500歐姆的電阻。LED顯示屏控制系統(tǒng) 簡單說分為:同步控制系統(tǒng)( 與計算機輸出內(nèi)容同步) ;異步脫機控制系統(tǒng)(將內(nèi)容存儲在控制卡內(nèi)，脫機運行)隨著近2 年LED顯示屏的飛速發(fā)展，LED控制系統(tǒng)的市場也變的更加廣闊美國HP公司在1996年三種顏色的LED燈推出的LED汽車尾燈模組可以隨意組合成各種汽車尾燈。天津投光燈性能</p><p
