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(guò)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(guò)某個(gè)閾值時(shí)，電流會(huì)出現(xiàn)指數(shù)式上升。通?？捎梅聪驌舸╇妷?，反向電流和正向電壓三個(gè)參數(shù)來(lái)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?，流過(guò)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(guò)高，大于某個(gè)閾值的時(shí)候，電流會(huì)指數(shù)式上升，沒(méi)有保護(hù)電路的話，一般會(huì)擊穿晶片；反向電壓一般為10V左右，大不得超過(guò)15V，否則會(huì)反向擊穿燈珠。（接反會(huì)導(dǎo)致反向電壓，過(guò)高會(huì)造成損壞）LED各類(lèi)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(guò)也有特意幾個(gè)晶片串聯(lián)一起的高壓燈珠，有6V，9V，18V，24V等。<span
