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(xué)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(xué)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(xué)器件。光學(xué)器件這個行業(yè)設(shè)計需要很專業(yè)的光學(xué)設(shè)計軟件，難度非常高。一般的光學(xué)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(xué)器件，透光率會更低一些。計算：設(shè)定光學(xué)透鏡的光透率是90%，那么通過電源和光學(xué)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℃。山東庫存LED導(dǎo)軌射燈上海先盛照明電器有限公司是一家專業(yè)提供LED的公司。</p><div

其實實際上并不是。根據(jù)晶片生成的特性，LED燈珠的驅(qū)動電壓是有浮動的，一般除了分色溫之外，還會區(qū)分電壓，特別在恒壓燈珠板應(yīng)用上，電壓區(qū)分很有必要。紅光的電壓一般比較低，大概在；白光和暖白光，一般電壓在,,。同樣的流明等級，電壓越低，光效越高，燈珠等級越好。藍光和紫外線燈珠比較高，一般在；CRI顯色指數(shù)光源對物體的顯色能力稱為顯色性，是通過與同色溫的參考或基準光源（白熾燈或太陽光）下物體外觀顏色的比較。忠實顯色：能正確表現(xiàn)物質(zhì)本來的顏色需使用顯色指數(shù)(Ra)高的光源，其數(shù)值接近100，顯色性好。效果顯色：要鮮明地強調(diào)特定色彩，表現(xiàn)美的生活可以利用加色的方法來加強顯色效果。采用低色溫光源照射，能使紅色更加鮮艷；采用中等色溫光源照射，使藍色具有清涼感；采用高色溫光源照射，使物體有冷的感覺。等級分數(shù)：分數(shù)分級等級應(yīng)用90-1001需要色彩精確對比的場所：博物館，商用，展廳80-891優(yōu)良需要色彩正確判斷的場所：辦公室，會議室60-792普通需要中等顯色性的場所：作業(yè)車間40-593一般對顯色性的要求較低，色差較小的場所：倉庫20-394較差對顯色性無具體要求的場所：路燈統(tǒng)計的15種顏色：R1，淡灰紅色；R2，暗灰黃色；R3：飽和黃綠色；R4。</p><p>led線條燈和led護欄管主要用于勾勒大樓建筑輪廓或是組成一個動態(tài)的大屏幕，而led洗墻燈主要是打光照射建筑外墻亮化。led投光燈是對建筑柱子或者頂部局部打亮。它的照射高度比較高，但燈光寬度范圍不遠。led點光源對建筑主要是起到點綴燈光作用。很多樓體會在每層裝一個點光源用來點綴。不過還有一個作用是用來做動態(tài)點陣屏。樓體亮化工程在接到亮化工程項目時，一定要先針對大樓設(shè)計好亮化效果圖，先讓客戶確定效果圖?？蛻魸M意后，我們在根據(jù)效果圖選擇適合的led亮化燈具，然后根據(jù)建筑的CAD圖紙算出具體需要的燈具數(shù)量，我們在根據(jù)具體數(shù)量配好開關(guān)電源和控制器。一定要注意如果有l(wèi)ed投光燈和led洗墻燈這些的話，要先看效果圖上面燈具具體要照射的高度是多少，在根據(jù)這個來選擇燈具光源透鏡度數(shù)和功率大小。因為不同透鏡度數(shù)和不同功率，照射的高度是不一樣的。所以建議接到項目時，一定要選擇一家專業(yè)的，有經(jīng)驗和值得信賴的led亮化燈具廠家。戶外樓體亮化是城市夜景亮化很重要的一部分，不僅美化了城市，也提升了城市的形象，可以很好的宣傳城市的**度，讓城市的夜景變得更吸引人。戶外樓體亮化與城市的整體規(guī)劃有很密切的聯(lián)系，是城市夜景亮化很重要的組成部分。LED，就選上海先盛照明電器有限公司，用戶的信賴之選，歡迎新老客戶來電！</p><div

等于單位時間內(nèi)某一波段的輻射能量和該波段的相對視見率的乘積。由于人眼對不同波長光的相對視見率不同，所以不同波長光的輻射功率相等時，其光通量并不相等。光通量的單位為“流明”。光通量通常用Φ來表示，在理論上其單位相當于電學(xué)單位瓦特，因視覺對此尚與光色有關(guān)。所以依標準光源及正常視力度量單位采用“流明”，符號：lm。由于人眼對不同波長的光的視見函數(shù)不同，所以不同的波長的光的輻射功率即使相等，其光通量并不相等。例如當波長為5500的綠光與波長為6500?的紅光輻射功率相同時，前者的光通量為后者的10倍。光通量是每單位時間到達、離開或通過曲面的光強度；光通量是燈泡發(fā)出亮光的比率。簡單來說：是衡量光源輸出光多少的指標。一個普通的燈泡，它輸出的所有光全部算在一起后就是這個燈泡光通量的具體數(shù)值?？梢园阉斫鉃椋阂粋€噴頭噴出了水，用一個氣球?qū)姵龅拿恳坏嗡佳b在里面，有多少裝多少，這就是光通量的含義。照度：照度的單位是勒克斯，符號表示為lx。它的定義是落在單位面積上光通量的大小，換而言之，也就是1平方米得到1流明的光叫做1個勒克斯。lx=lm/m^2同樣也可以用水來作一個比方：噴頭會噴很多水出來。LED，就選上海先盛照明電器有限公司，讓您滿意，歡迎您的來電！湖南實惠LED燈管</p><p
