大家(jia)好我是天成照明LED燈(deng)珠(zhu)廠家(jia)小編燈(deng)漂(piao)亮今天我們來介紹led燈(deng)珠(zhu)單個亮度 led燈(deng)珠(zhu)沒壞就是不(bu)亮怎么維修(xiu)的(de)問(wen)題，以下就是燈(deng)漂(piao)亮對此(ci)問(wen)題和(he)相關問(wen)題的(de)歸納整理,一起來看看吧。 文章目錄導航: led燈只有一個燈珠亮是什么原因 要(yao)是(shi)燈珠壞了的(de)話，燈帶一般(ban)都會(hui)發污，或(huo)者(zhe)都都不亮。 LED控制器LED controller就(jiu)是(shi)通過(guo)芯片(pian)處理控制LED燈電(dian)路中的(de)各個(ge)位(wei)置的(de)開關。 控(kong)制器(qi)根據預先設(she)定(ding)好的程序再控(kong)制驅動電路使LED陣列(lie)有規律地發光，從而顯(xian)示(shi)出文字(zi)或圖形。 變色燈里(li)(li)(li)面其實(shi)是(shi)封裝了幾(ji)個(ge)顏色的芯(xin)片(pian)，其實(shi)就是(shi)把幾(ji)個(ge)燈裝在(zai)一(yi)個(ge)殼里(li)(li)(li)面，里(li)(li)(li)面還配了一(yi)個(ge)芯(xin)片(pian)控制(zhi)幾(ji)個(ge)燈輪流(liu)閃亮。
LED燈珠的流明是多少 LED英文為(wei)（light emitting diode） ，LED燈珠(zhu)就是發(fa)光二極管的(de)英文縮寫簡稱(cheng)(cheng)LED，這是一(yi)個(ge)通俗(su)的(de)稱(cheng)(cheng)呼。 1、亮度 LED燈珠的亮度不同，價格不同。 燈珠：一般亮度為(wei)60-70 lm球泡燈：一般亮度為(wei)80-90 lm。 1W紅光(guang)，亮(liang)度(du)(du)一(yi)般為(wei)(wei)30-40 lm1W綠光(guang)，亮(liang)度(du)(du)一(yi)般為(wei)(wei)60-80 lm1W黃(huang)光(guang)，亮(liang)度(du)(du)一(yi)般為(wei)(wei)30-50 lm1W藍光(guang)，亮(liang)度(du)(du)一(yi)般為(wei)(wei)20-30 lm。 注：1W亮度為(wei)60-110lm3W亮度最高可達240lm5W-300W是集(ji)成芯片，用串(chuan)/并聯(lian)封(feng)裝(zhuang)，主要看多少電流，電壓，幾串(chuan)幾并。 LED透鏡：一次透鏡一般用(yong)PMMA、PC、光學玻璃、硅(gui)膠（軟(ruan)硅(gui)膠，硬(ying)硅(gui)膠）等(deng)材料(liao)。角度越(yue)(yue)大出光效率越(yue)(yue)高，用(yong)小角度的(de)LED透鏡，光線要(yao)射得遠(yuan)的(de)。 LED所有燈珠參數 1、亮度 LED燈(deng)珠的(de)亮度不同(tong)(tong)，價格不同(tong)(tong)。 燈(deng)杯：一般(ban)亮度為60-70lm球泡燈(deng)：一般(ban)亮度為80-90lm。 1W紅光，亮(liang)度(du)一(yi)(yi)般為30-40lm1W綠光，亮(liang)度(du)一(yi)(yi)般為60-80lm1W黃光，亮(liang)度(du)一(yi)(yi)般為30-50lm1W藍光，亮(liang)度(du)一(yi)(yi)般為20-30lm。 注：1W亮度為60-110lm3W亮度最(zui)高可達240lm5W-300W是集成芯片(pian)，用串(chuan)/并(bing)聯封(feng)裝，主(zhu)要看多少電流(liu)，電壓，幾(ji)串(chuan)幾(ji)并(bing)。 怎樣檢測單個led燈珠是否亮的手段 用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)和(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻檔測。5730燈珠正(zheng)(zheng)向(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)是約(yue)0.5至(zhi)0.1nF、反(fan)向(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)比正(zheng)(zheng)向(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)稍(shao)小、不(bu)同品牌和(he)型(xing)號測出(chu)(chu)(chu)的(de)(de)不(bu)一(yi)樣、有(you)的(de)(de)正(zheng)(zheng)反(fan)向(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)都(dou)可(ke)低至(zhi)約(yue)0.07nF。是以上(shang)值的(de)(de)、能(neng)用(yong)3.3伏(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)點亮且亮度(du)正(zheng)(zheng)常、都(dou)算正(zheng)(zheng)常。用(yong)3.3伏(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)試(shi)纔(cai)是關鍵。3.3伏(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)竝不(bu)難找、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦上(shang)就有(you)、一(yi)般充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)上(shang)都(dou)有(you)、編(bian)程(cheng)器(qi)上(shang)亦(yi)有(you)。沒辦法接出(chu)(chu)(chu)3.3伏(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)話、用(yong)5伏(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)亦(yi)可(ke)。一(yi)般手機充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)輸出(chu)(chu)(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓是5伏(fu)(fu)(fu)、5伏(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)試(shi)一(yi)下竝不(bu)會(hui)燒壞燈珠。5730燈珠大多(duo)可(ke)承受6.667伏(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。正(zheng)(zheng)常LED燈珠冷態正(zheng)(zheng)反(fan)向(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻都(dou)很(hen)大、用(yong)一(yi)般萬(wan)用(yong)表測不(bu)出(chu)(chu)(chu)。壞LED燈珠有(you)的(de)(de)仍能(neng)亮、但亮度(du)不(bu)足、能(neng)被一(yi)般萬(wan)用(yong)表測出(chu)(chu)(chu)冷態電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻。 LED大功率單顆燈珠和貼片用的燈珠流明是否一樣 貼(tie)片燈珠是小功率(lv)的，一般在0.2-0.5W之間(jian)。 大功率(lv)燈珠是在1-3W之間。 如果折算成每瓦的(de)流明(ming)的(de)話(hua)，那流明(ming)數還是比較(jiao)接近的(de)。主(zhu)要(yao)是看用(yong)什么(me)芯片，像做得好的(de)有普(pu)瑞 晶元 三安(an)。 也有國產的合金(jin)線（不是金(jin)線），亮度和壽命會偏低(di)些。 所(suo)以籠統的說是(shi)說不上來哪個流明更高，因(yin)為(wei)做(zuo)法都(dou)不一樣(yang)。大(da)體上講是(shi)差不多的。 以上就是(shi)天成小編(bian)對于led燈珠單個亮度 led燈珠沒壞(huai)就是(shi)不亮怎(zen)么維修問題和相關問題的(de)解(jie)答了，希望對你有用 【責任編(bian)輯：燈漂亮】 |
