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。</p><p>需求根據(jù)廠家供應的規(guī)范法蘭盤規(guī)范，運用M16或M20(常用規(guī)范)螺桿焊接成基礎(chǔ)籠，然后在設(shè)備地址，經(jīng)行挖掘合適規(guī)范的坑洞，把基礎(chǔ)籠放置其間，水平矯正后，運用水泥混凝土灌溉以固定基礎(chǔ)籠，3-7日后水泥混凝土充沛凝結(jié)，即可設(shè)備院子燈。(留神:LED院子燈基礎(chǔ)澆筑時需求把預埋的管線引出)。首要功用不同款式的LED院子燈裝扮著城市LED院子燈發(fā)展到21世紀，被運用于城市慢車道、窄車道、居民小區(qū)、旅行景區(qū)、公園、廣場、私家花園、院子走廊等公共場所的旅程單側(cè)或倆冊用來旅程照明，跋涉人們夜間出行的安全性用來增加人們戶外活動的時刻，跋涉生命產(chǎn)業(yè)的安全。它還可以改悅耳們的心境，跋涉人的心境，而且可以改悅耳的觀念，發(fā)明一個明暗相間的調(diào)色板般的夜晚。白日，院子燈可以點綴城市風景;夜晚，院子燈具既能供應必要的照明及日子便當，增加居民安全感，又能突顯城市亮點，演繹亮麗風格，以至于沿用至今，現(xiàn)已發(fā)展為老到的產(chǎn)業(yè)鏈。LED，就選上海先盛照明電器有限公司，有需求可以來電咨詢！</p><div

也有設(shè)計的非常好的隔離驅(qū)動，也是可以做到效率高達92-93%計算：設(shè)定電源效率是85%，那么100W的電功率算上損耗是100/，那么實際光效就是：10000/。光學器件：一般照明燈具，特別是窄光束角的光源，需要用二次光學設(shè)計，以達到所需求的配光要求。一般有反光杯，透鏡，防眩光杯這些光學器件。光學器件這個行業(yè)設(shè)計需要很專業(yè)的光學設(shè)計軟件，難度非常高。一般的光學級透鏡或者反光杯的透光率，都不超過90%。一些防眩光高的，或者光束角窄的光學器件，透光率會更低一些。計算：設(shè)定光學透鏡的光透率是90%，那么通過電源和光學透鏡這兩個組成部分得出的光效為：10000*。熱效率：燈具外殼對LED光源的熱管理的效率。通常燈具將PCB板，燈殼用來做散熱通道，實現(xiàn)熱失散，對燈具有一系統(tǒng)熱阻的設(shè)計問題，也就是好的散熱系統(tǒng)。LED的PN結(jié)上溫度Tj與燈具環(huán)境溫度Ta之間的溫度梯度越小越好。燈具的系統(tǒng)熱阻=燈具外殼（或者內(nèi)部平均溫度）與環(huán)境溫度之差，與燈具功率之比。Rthsystem=(Tscase?Ta)/Pin(℃/w)Rthsystem=(Tscase-Ta)/Pin(℃/w)Rthsystem=(Tscase?Ta)/Pin(℃/w)假設(shè):LED的熱阻為8℃/w，則一個LED上加1w電功率后，LEDPN結(jié)上的溫度Tj與底座散熱底板之間溫差為8℃。浙江大功率LED燈具</p></p><br
