led燈珠電阻對照表

一、2V左右點(dian)亮(liang)的(de)LED燈(如紅、黃、橙等)：

12V：470歐車上12V：680歐

二：3V左右點(dian)亮(liang)的LED燈(deng)(如(ru)藍、綠、白等)：

12V：390歐車上12V：470歐

電阻(zu)的參(can)數(shu)一般有兩(liang)個，阻(zu)值(zhi)R和功率P。

R=（U-Uled）/Iled，USB的(de)標(biao)準(zhun)電壓是DC5V的(de)，所以R=（5-Uled）/Iled

Uled，燈(deng)珠的正向(xiang)導(dao)通(tong)電壓。Iled，燈(deng)珠的正向(xiang)導(dao)通(tong)電流。

現在LED有(you)很多種類，顏色不同，一(yi)般電流也不同。

電阻大(da)小(xiao)影響電流大(da)小(xiao)，進而影響燈(deng)珠(zhu)的亮度(du)，但只(zhi)要不(bu)超過(guo)正向最大(da)電流，都可(ke)以使(shi)用，只(zhi)是亮度(du)或有不(bu)同(tong)，所以選擇范圍比較大(da)

LED燈珠的參數說明

1、亮度

LED燈珠的亮度不(bu)同(tong)，價格不(bu)同(tong)。

燈珠：一般亮度為(wei)60-70lm球泡燈：一般亮度為(wei)80-90lm。

1W紅光，亮(liang)度一(yi)般(ban)(ban)為30-40lm1W綠光，亮(liang)度一(yi)般(ban)(ban)為60-80lm1W黃光，亮(liang)度一(yi)般(ban)(ban)為30-50lm1W藍光，亮(liang)度一(yi)般(ban)(ban)為20-30lm。

注：1W亮度為(wei)60-110lm3W亮度最高可達240lm5W-300W是(shi)集(ji)成芯(xin)片(pian)，用(yong)串/并(bing)聯封(feng)裝，主要看多少電流，電壓，幾串幾并(bing)。

LED透(tou)(tou)鏡：一次透(tou)(tou)鏡一般用PMMA、PC、光(guang)學玻(bo)璃、硅膠（軟硅膠，硬硅膠）等(deng)材料(liao)。角(jiao)(jiao)度越大出(chu)光(guang)效率越高，用小角(jiao)(jiao)度的LED透(tou)(tou)鏡，光(guang)線要射得遠的。

2、波長

波長一(yi)致，顏色(se)一(yi)致。則價(jia)格高。

白光分暖色(se)（色(se)溫2700-4000K），正(zheng)白（色(se)溫5500-6000K），冷白（色(se)溫7000K以上(shang)）歐(ou)洲人比較喜歡暖白。

紅(hong)(hong)光：波(bo)段600-680，其中620，630主要用于舞臺(tai)燈，690接近(jin)紅(hong)(hong)外(wai)線。

藍光：波段430-480，其中460，465舞臺燈用的較多。

綠光：波(bo)段500-580，其中525，530舞臺燈用的(de)較多。

3、發光角度

用(yong)途不同的LED其發(fa)(fa)光角(jiao)度(du)(du)不一樣(yang)。特殊(shu)的發(fa)(fa)光角(jiao)度(du)(du)，價格(ge)較(jiao)高(gao)。

4、抗靜電能力

抗(kang)靜電能力強的(de)LED燈(deng)(deng)珠，壽命長(chang)，因而價格(ge)高。通常抗(kang)靜電大于700V的(de)LED燈(deng)(deng)珠才能用(yong)于LED燈(deng)(deng)飾。

5、漏電電流

LED燈(deng)珠(zhu)是(shi)單(dan)向(xiang)導電(dian)的(de)發光體，如果有反向(xiang)電(dian)流，則稱為漏電(dian)，漏電(dian)電(dian)流大(da)的(de)LED燈(deng)珠(zhu)，壽命短，價(jia)格低。

LED燈珠多少lm等1w

理論上是計算(suan)方法是對。LED有額定的流明，也有額定的電流和電壓，額定功(gong)率，比如0.5w一顆燈(deng)珠。常見的參數為(wei)5730，0.5w，150ma，5055LM，3.1v3.3v。常見電路板(ban)是2并多(duo)串(chuan)，24w就是2并24串(chuan)。還有2835，1w一顆6V，150ma，100110LM。說到燈(deng)具成品(pin)，常見是2種方法，1是足夠(gou)的電流和優良(liang)散熱器，2是降低電流和足夠(gou)散熱。實(shi)際是680720LM吧

接一個LED燈珠需要加多大電阻

一、2V左右點亮(liang)的(de)LED燈(如(ru)紅、黃、橙等): 12V:470歐(ou)(ou)車(che)上12V:680歐(ou)(ou) 二:3V左右點亮(liang)的(de)LED燈(如(ru)藍、綠、白等): 12V:390歐(ou)(ou)車(che)上12V:470歐(ou)(ou)
