半導(dǎo)體的物理伏安特性伏安特性所謂伏安特性，即是流過P-N結(jié)的電流隨電壓變化的特性，在示波器上能十分形象地展示這種變化。一根完整的伏安曲線包括正向特性與反向特性。通常，反向特性曲線變化較為陡峭，當(dāng)電壓超過某個閾值時，電流會出現(xiàn)指數(shù)式上升。通常可用反向擊穿電壓，反向電流和正向電壓三個參數(shù)來進(jìn)行伏安特性曲線的描述。所以，LED的工作前提：LED屬于半導(dǎo)體，有單向?qū)щ娦裕鬟^的電流和電壓不成線性正比。LED光通量隨電流增大而增大，但也不成正比。工作在低壓的直流電下，一般電壓在2-5VDC之間，紅光一般工作低壓低，藍(lán)光（白光）工作電壓在3-4V，而紫外光電壓在4-5V之間；電壓不能過高，大于某個閾值的時候，電流會指數(shù)式上升，沒有保護(hù)電路的話，一般會擊穿晶片；反向電壓一般為10V左右，大不得超過15V，否則會反向擊穿燈珠。（接反會導(dǎo)致反向電壓，過高會造成損壞）LED各類型封裝芯片的一般額定電壓，額定電流表格SMD中小功率SMD中小功率封裝形式的電壓，電流都不一定的。一般是3-5V，不過也有特意幾個晶片串聯(lián)一起的高壓燈珠，有6V，9V，18V，24V等。<span

而LED基板與PCB之間的熱阻一般是℃/w（鋁基板的熱阻一般小于℃/w),那么Tj與PCB板之間溫差為8+℃。燈具散熱材料，一般壓鑄鋁（鋁合金的熱阻一般*為℃/w)，那么燈殼到LEDPN結(jié)之間的溫差約為：（8+）=℃?，F(xiàn)在問題是：燈殼Tscase與燈周邊環(huán)境溫度Ta的溫度差多少？這是由燈具的系統(tǒng)熱阻決定的。加入用于熱失散的燈殼接觸環(huán)境空間的面積為A，此面積大小就決定了兩者之間的溫差。當(dāng)A趨于無窮大時，燈殼與環(huán)境等溫。這是做不到的。日本西鐵城等公司，測算出散熱器面積與Tj的關(guān)系曲線。一個，要使Tj從100℃下降到80℃，散熱器與空氣接觸面積要增加60平方里面以上，由此可估算：60cm2/；每增加1W電功率的LED，若用60平方厘米以上的散熱器時，其Tj結(jié)溫將下降20℃。計算：那么用約用℃。那么，燈具系統(tǒng)熱阻Rthsystem=20/℃/w；于是對燈具施加，在Ta=25℃時，燈殼上的溫度應(yīng)該是：Tscase=25℃+℃；此時，通過前面的計算，我們可以知道LEDPN結(jié)溫是：Tj=45+℃；PN結(jié)溫Tj比起光效值100lm/WTj=25℃的時候，高了（）=℃；也就是一個100lm的LED光通量較Tj=25℃的時候要低：；100個LED等于比Tj=25℃時候，低；由此可以得知燈具的熱效率=（1-735/10000)=。所以：三個部分疊加后。江蘇專業(yè)LED有哪些</p></p><br
