環(huán)保LED軟燈條組成資料不論是LED仍是FPC，其質料都是選用的環(huán)保質料，歸于可回收運用型，不會因為許多運用而構成對環(huán)境的污染和損壞。6.安全LED軟燈條選用的是低壓直流12V供電電壓，因此運用上十分安全。不論白叟、小孩都可以安全運用而不會引起安全隱患。7.簡易設備LED軟燈條設備十分簡潔，配用固定夾、線槽、鐵線、鐵網(wǎng)等即可設備在多種支承面上。其他，因為LED軟燈條輕、薄，因此，選用雙面膠也可以結束固定的功用。無需專業(yè)人員即可設備，可以真實享受DIY的裝飾愛好。8.壽數(shù)長LED軟燈條的正常運用壽數(shù)是8~10萬小時，每天24小時不斷的作業(yè)，其壽數(shù)都差不多近10年。因此，LED軟燈條的壽數(shù)是傳統(tǒng)燈具的好幾倍。9.使用范圍LED軟燈條因為柔軟、輕浮、色彩樸實等特征，被使用于樓體概括，臺階，展臺，橋梁，酒店，KTV裝飾照明，以及廣告招牌的制造、各種大型動畫、字畫的廣告設計等場所。跟著LED軟燈條技能的逐步老練，其使用范圍將愈加。湖南LED用途LED，就選上海先盛照明電器有限公司，用戶的信賴之選。</p><div

基本的發(fā)光原理并沒有太大的變化：在兩層半導體之間，電子和與空穴碰撞復合并于發(fā)光層產(chǎn)生了藍色的光子。所產(chǎn)生的藍光有一部分會直接穿過熒光涂層直接發(fā)射出去;剩下的一部分會打在熒光涂層上并與之作用產(chǎn)生黃色光子。藍色光子與黃色光子共同作用（混合）就產(chǎn)生了白光。上圖是一個LED的光譜曲線：可以看到藍光峰值位于波長450納米處，而之后稍微低矮一點的峰值是由熒光粉吸收藍光后所產(chǎn)生的黃光的峰值。如果藍光的占比多一點，則產(chǎn)生高色溫的白光;相反，如果黃光占比多一點，則產(chǎn)生色溫較低的白光。所以：白光的熒光粉偏淺黃，中性光的熒光粉偏黃，而暖光的熒光粉橙色，高顯色的暖光更偏紅。LED燈的發(fā)光原理baijiahao./s?id=68700610&wfr=spider&for=pcLED燈珠的封裝形式引腳插入行（DIP)俗稱：草帽燈珠，有兩個插件腳。是簡單，也便宜的燈珠形式。特點：安全性好，性能穩(wěn)定，在低電壓的情況下就可以發(fā)光，并且低損耗、效能高、壽命長。不過一般功率偏低，而且應用范圍一般在于車燈，指示燈，顯示屏里面。這些功率一般在。中小功率表面貼裝性（SMD)這種燈珠光源是將發(fā)光二極管焊接在電路板表面，而不是穿過電路板。它的體積小，這類燈珠的型號有很多，常用的有2835。上海先盛照明電器有限公司為您提供LED，歡迎您的來電哦！湖南實惠LED燈管</p><p

style="text-indent:25px">脈沖調頻調光法脈沖調頻調光法（PFM）也是常用的調光方法。如果高頻交流電子鎮(zhèn)流器的開關工作頻率增加，則鎮(zhèn)流電感的阻抗增加，這樣流過鎮(zhèn)流電感的電流就會下降，導致流過燈負載的電流下降，從而實現(xiàn)調光。圖2為4英尺40W熒光燈脈沖調頻調光法的調光特性曲線（脈沖占空比D=0.45）脈沖調頻調光法的局限性。調光范圍由調頻范圍決定，如果調頻范圍不大，則熒光燈功率調節(jié)范圍也不大。為了實現(xiàn)在低熒光燈燈功率工作條件下實現(xiàn)調光，則調頻范圍應很寬（即從25~50kHz）。湖南LED用途</p></p><br
