led燈珠的光衰正常是多少

1、國家(jia)(jia)是沒(mei)有(you)標(biao)準(zhun)的(de)，行業內部標(biao)準(zhun)為(wei)(wei)：1000小(xiao)時光(guang)衰為(wei)(wei)0。 3000小(xiao)時光(guang)衰為(wei)(wei)1% 10000小(xiao)時光(guang)衰為(wei)(wei)3% 。5萬小(xiao)時光(guang)衰不大(da)于(yu)30%就(jiu)可以。一般能達到上面(mian)光(guang)衰的(de)廠(chang)家(jia)(jia)都是相當正(zheng)規的(de)廠(chang)家(jia)(jia)。外面(mian)很多廠(chang)家(jia)(jia)用(yong)的(de)都不是很好的(de)芯片。要想(xiang)買到好的(de)LED建(jian)議你去找下國家(jia)(jia)三(san)部委中標(biao)的(de)28家(jia)(jia)LED燈具企業購買

2、沒有國家標準，可(ke)參考(kao)美國能源(yuan)之星LM-80標準。

6000H，光(guang)通量維持率≥94.1%。

LED燈珠簡介：

LED燈(deng)珠(zhu)就是發光(guang)二極(ji)管的英文縮(suo)寫簡(jian)稱LED。以下為LED燈(deng)珠(zhu)特點(dian)：

1. 電(dian)壓(ya)： LED燈珠使(shi)(shi)用(yong)低(di)壓(ya)電(dian)源(yuan)，供電(dian)電(dian)壓(ya)在 2-4V之間，根據產品不(bu)同而異，所以它是(shi)一個比使(shi)(shi)用(yong)高壓(ya)電(dian)源(yuan)更安全的電(dian)源(yuan)，特別適(shi)用(yong)于公共場所

2.電(dian)流：工作電(dian)流在0—15mA，亮度隨(sui)電(dian)流的(de)增大而變量

3. 效(xiao)能：消耗(hao)能量(liang)較同(tong)光效(xiao)的白(bai)熾燈減少(shao) 80%。

4. 適用性(xing)：很小(xiao)(xiao)，每個單元 LED 小(xiao)(xiao)片是 3-5mm 的正方形，所以可(ke)以制備成各種形狀的器件，并(bing)且適合于易變的環境(jing)。

5. 穩定性： 10 萬小(xiao)時(shi)，光衰(shuai)為初(chu)始的 50%。

6. 響(xiang)應(ying)(ying)時間(jian)：其白熾(chi)燈的(de)響(xiang)應(ying)(ying)時間(jian)為(wei)毫(hao)秒(miao)級， LED 燈的(de)響(xiang)應(ying)(ying)時間(jian)為(wei)納(na)秒(miao)級。

7. 對環境(jing)污染：無有(you)害金屬汞。

8. 顏(yan)色：改變電流(liu)可以(yi)變色，發(fa)光(guang)二極管(guan)方便地通過化學修飾方法，調整材(cai)料的能帶結構和帶隙，實(shi)現紅黃綠蘭橙多色發(fa)光(guang)。如小電流(liu)時為紅色的 LED ，隨著電流(liu)的增加(jia)，可以(yi)依次(ci)變為橙色，黃色，最(zui)后為綠色。

9. 價格(ge)： LED燈(deng)(deng)珠(zhu)的成本價格(ge)相應對于傳統新光(guang)源來說(shuo)要貴(gui)些(xie)，較之 于白(bai)熾燈(deng)(deng)，幾十只(zhi)白(bai)光(guang) LED 的價格(ge)就可(ke)以與一只(zhi)白(bai)熾燈(deng)(deng)的價格(ge)相當，而通常每組信號燈(deng)(deng)需(xu)由上 300 ～ 500 只(zhi)二極管構(gou)成。

國(guo)家(jia)(jia)是沒有標(biao)準(zhun)(zhun)的(de)(de)(de)(de)(de)，行業內部標(biao)準(zhun)(zhun)為(wei)：1000小(xiao)(xiao)時(shi)光衰(shuai)(shuai)(shuai)為(wei)0。3000小(xiao)(xiao)時(shi)光衰(shuai)(shuai)(shuai)為(wei)1%10000小(xiao)(xiao)時(shi)光衰(shuai)(shuai)(shuai)為(wei)3%。5萬小(xiao)(xiao)時(shi)光衰(shuai)(shuai)(shuai)不大于30%就可以。一般能達(da)到(dao)上面光衰(shuai)(shuai)(shuai)的(de)(de)(de)(de)(de)廠家(jia)(jia)都(dou)是相當正規(gui)的(de)(de)(de)(de)(de)廠家(jia)(jia)。外面很多(duo)廠家(jia)(jia)用的(de)(de)(de)(de)(de)都(dou)不是很好的(de)(de)(de)(de)(de)芯片(pian)。要想買(mai)到(dao)好的(de)(de)(de)(de)(de)LED建議你去找下(xia)國(guo)家(jia)(jia)三部委中標(biao)的(de)(de)(de)(de)(de)28家(jia)(jia)LED燈(deng)具企業購買(mai)2、沒有國(guo)家(jia)(jia)標(biao)準(zhun)(zhun)，可參考美國(guo)能源之星LM-80標(biao)準(zhun)(zhun)。
