led燈波長范圍和亮度

LED芯片各個顏(yan)色(se)波(bo)段對照(zhao)表(單位：納米(nm)紅光(guang)：615-650橙色(se)：600-610黃(huang)色(se)：580-595黃(huang)綠：565-575綠色(se):495-530藍(lan)光(guang)：450-480紫色(se)：370-410白光(guang)：450-465，led燈的亮度波(bo)長在400到550之(zhi)間是(shi)成正比(bi)關系，在550之(zhi)后就是(shi)反比(bi)了(le)。

LED燈珠的流明是多少

色溫(wen)：簡單點(dian)說就是(shi)用來表(biao)示(shi)光(guang)源(yuan)光(guang)色尺(chi)度的（單位為(wei)K）。根據(ju)定義打個比(bi)方吧：例如色溫(wen)3000K。就是(shi)假(jia)設(she)有一個絕對黑體，將其加熱到(dao)2727℃（-273℃為(wei)溫(wen)度起點(dian)）時(shi)發(fa)出的光(guang)進行比(bi)較。其實就是(shi)以溫(wen)度來表(biao)示(shi)光(guang)色的。

流(liu)明(ming)值：它其實是光(guang)通量(liang)的(de)單位流(liu)明(ming)（lm）。是一(yi)個(ge)表(biao)征亮度程度的(de)單位。簡單定義就(jiu)是指蠟燭一(yi)燭光(guang)在1公尺以外(wai)所顯現(xian)出的(de)亮度。流(liu)明(ming)值越(yue)(yue)高說(shuo)明(ming)燈越(yue)(yue)亮。

LED小功率的燈的參數VF、IV、WL、BIN這些都是表示什么流明跟這些有什么關系

VF指的(de)是LED的(de)工作電壓。

IV指(zhi)的(de)是LED的(de)亮度。

WL指的(de)是LED的(de)主波長。

BIN值的(de)是(shi)公司內部分光檔次(ci)。

流(liu)明，光(guang)(guang)通(tong)(tong)量的(de)(de)單(dan)位。發光(guang)(guang)強度(du)為(wei)1坎(kan)德拉(cd)的(de)(de)點光(guang)(guang)源(yuan)，在單(dan)位立體(ti)角（1球面度(du)）內發出的(de)(de)光(guang)(guang)通(tong)(tong)量為(wei)1流(liu)明，英文(wen)縮寫(xie)(lm)。

所(suo)謂的(de)流(liu)明簡單(dan)來說(shuo)，就(jiu)是指蠟燭一(yi)燭光在一(yi)公(gong)尺（1 公(gong)尺 = 1 米）以外的(de)所(suo)顯現(xian)出的(de)亮(liang)度。

一(yi)個普(pu)通(tong)(tong)40瓦(wa)的白(bai)熾燈(deng)泡，其發光(guang)(guang)(guang)效率大約是每(mei)瓦(wa)10流明，因此可以發出400流明的光(guang)(guang)(guang).。40瓦(wa)的白(bai)熾燈(deng)220伏時，光(guang)(guang)(guang)通(tong)(tong)量(liang)為(wei)340流明。

光(guang)通量是描(miao)述單位時間內(nei)光(guang)源輻射產(chan)生視覺(jue)響應強(qiang)弱(ruo)的能力，單位是流明，也叫明亮度。

投(tou)影儀(yi)表示光通量(liang)(liang)的單位是ANSI流明，ANSI流明是美國(guo)國(guo)家標準化協(xie)會制定的測量(liang)(liang)投(tou)影儀(yi)光通量(liang)(liang)的標準，它(ta)測量(liang)(liang)屏幕\"田(tian)\"字形九(jiu)個交叉點上的各點照度(du)，乘以面積，再求九(jiu)點的平均值(zhi)，即(ji)為該(gai)投(tou)影儀(yi)的ANSI流明。

流明(ming)值越(yue)(yue)高表(biao)示越(yue)(yue)亮，明(ming)亮度越(yue)(yue)高則在投影時就不需(xu)要關燈。 ANSI為(wei)American National Standards Institute（美國(guo)國(guo)家標準局）的縮寫。

led燈珠紅燈的常規波段是多少

LED燈珠發(fa)光(guang)的波長主要看里面(mian)的LED芯(xin)片的波長：紅(hong)光(guang)LED燈珠一般波長范(fan)圍(wei)在610-650nm。如(ru)下波長參考圖：
