(二)商場(chǎng)照明商場(chǎng)照明的目的是為了吸引顧客并提高他們的購(gòu)物欲望，因此照明設(shè)計(jì)要突出商場(chǎng)，更要突出商品，商場(chǎng)的照明要求一般色溫在6000K以上，照度要求在600LUX以上.并且分布均勻,顯色性高，一般來(lái)說(shuō)在大賣場(chǎng)區(qū)城當(dāng)高度大于6米時(shí)，采用點(diǎn)光源，高度小于6米時(shí),采用線光源(光帶).在肉制品/熟食區(qū)、面包房、水果、蔬菜區(qū)城照度要求不低于1000LUX.</p><p>LED面板燈導(dǎo)光板工作原理：當(dāng)光從兩側(cè)光源進(jìn)入導(dǎo)光板碰到反射點(diǎn)時(shí)，漫反射到導(dǎo)光板表面：另一部分是光直接穿透導(dǎo)光板到達(dá)表面。越靠近光源的LED導(dǎo)光板部位得到的直接光越強(qiáng)，遠(yuǎn)離的較弱;而另一方面，靠近光源的反射點(diǎn)細(xì)小而疏遠(yuǎn)，漫反射出來(lái)的光較少。LED面板燈導(dǎo)光板設(shè)計(jì)原理介紹：面板燈導(dǎo)光板是以光學(xué)級(jí)亞克力為基材，運(yùn)用LCD顯示屏和背光模組技術(shù)，透過(guò)導(dǎo)光點(diǎn)的全高透光率，經(jīng)電腦對(duì)導(dǎo)光點(diǎn)設(shè)計(jì)使導(dǎo)光板光線折算成面光源均光狀態(tài)制造成型。LED面板燈導(dǎo)光板熔點(diǎn)：LED面板燈導(dǎo)光板一般采用PC料，PC是無(wú)定型材料無(wú)固定熔點(diǎn)。以Makrolon2405為例玻璃態(tài)轉(zhuǎn)化溫度和Vicat軟化點(diǎn)都是145度，成型溫度是280度。LED面板燈導(dǎo)光板和擴(kuò)散板有什么不同：從材質(zhì)上來(lái)說(shuō)：擴(kuò)散板基材是PCLED面板燈導(dǎo)光板基材是PMMA從功能性來(lái)說(shuō)：擴(kuò)散板主要作用為：1、打散光通量,讓光均勻分布(部分復(fù)合擴(kuò)散板除了讓光均勻化,還可以控制出射角度)。2、支撐背光架構(gòu),保護(hù)下面的光學(xué)材料受損。LED導(dǎo)光板主要作用：1、引導(dǎo)LED點(diǎn)光源的光通量均勻分布在整個(gè)面內(nèi).他的關(guān)鍵作用在于對(duì)光線的引導(dǎo)分布。2、利用反射機(jī)制更大效率的利用光通量以及控制光分布。LED面板燈應(yīng)用在安裝體(追求實(shí)用和藝術(shù)結(jié)合，方便簡(jiǎn)單安裝)

LED靠電子在能帶間的躍遷來(lái)發(fā)光，它光譜單一，不含紅外部分，不同于傳統(tǒng)的固體熱致發(fā)光光源的白熾燈。因此將LED稱作“冷”光源，其實(shí)LED芯片*能將不到10%的電能轉(zhuǎn)化為光能，其余90%轉(zhuǎn)化為熱能。而且這些熱能的大部分只能靠傳導(dǎo)散發(fā)出去。因此，良好的散熱設(shè)計(jì)對(duì)LED的正常使用非常重要。2、LED對(duì)工作溫度要求嚴(yán) LED的芯片對(duì)溫度異常敏感，這也是半導(dǎo)體的共性。從下列的圖及表格中可以看出LED的使用壽命與結(jié)溫(Tj)關(guān)系。那么接下來(lái)我們分析一下該產(chǎn)品的優(yōu)勢(shì)和當(dāng)下存在的問(wèn)題，好讓大家對(duì)該產(chǎn)品可以有一個(gè)更加***的了解。廣西室外三防燈</p><p
