Ndi Patch Ya LED Ndi Mikanda Ya Nyali Ya LED Ndi Zabwino Ziti?

Ndi chitukuko chofulumira chaukadaulo wa LED, kuyatsa kwa LED pang'onopang'ono kwakhala chisankho chabwino kwambiri pakuwunikira kwatsopano kobiriwira. LED ndi yabwino kwambiri kuposa zowunikira zachikhalidwe pamlingo wa mfundo zowala, kupulumutsa mphamvu ndi kuteteza chilengedwe. Nyali za LED zitha kugawidwa kukhala zigamba ndi mikanda. Kodi pali kusiyana kotani pakati pa zonsezi? Xiaobian amakambirana ngati ndi zomata za nyali za LED kapena mikanda ya nyale. Choyamba, tiyeni tiwone mawonekedwe a mikanda ya nyali ya LED? Ngodya ya mikanda ya nyali ya LED ndi yaying'ono kwambiri. Ndi ya kuwala kokhazikika kwambiri ndipo mawonekedwe ake ndi akutali, koma kuchuluka kwa kuwalako kumakhala kochepa. Ndiwofalikira kwa kuwala ndi kuwala kosiyanasiyana, koma mtunduwo uli pafupi kwambiri. Mikanda ya nyali ya LED imagwiritsa ntchito kutulutsa ndi kuwala, pomwe chigamba cha LED chimagwiritsidwa ntchito poyaka ozizira. Nyali za chigamba za LED zimapangidwa ndi bolodi lozungulira la FPC, kuwala kwa LED, manja apamwamba a silicone. Kuchita kwamadzi, gwiritsani ntchito chitetezo chamagetsi otsika -voltage DC, mtundu wosavuta, mitundu yosiyanasiyana, mitundu yowala; kugwiritsa ntchito panja kumatha kukana kukalamba kwa UV, chikasu, komanso kutentha kwambiri. Izi zimagwiritsidwa ntchito kwambiri pomanga magetsi ozungulira, kuyatsa kokongola kolondola kwa malo osangalatsa, zokongoletsera zotsatsa, zokongoletsera zotsatsa Kuwala kounikira. Mosiyana ndi zimenezo, ubwino wa chigamba ndi chiyani? Chigamba cha LED ndi mtundu wa mikanda ya nyali ya LED. Ma LED wamba akuphatikizapo singano ziwiri kapena zinayi, ndipo palibe mapazi ooneka ngati singano. Chinsinsi chosankha mikanda ya nyali ndikuganizira kutentha kwa mtundu, index yopereka mitundu, kuwala, kulephera kwa kuwala, komanso mtundu wa magetsi, ndi zina zotero, gulani zinthu izi ndikugula zinthu izi. Opanga Zhuhai ali ndi zaka zambiri zaukadaulo mumakampani a LED, ndipo ophunzira amatulutsa mikanda ya nyali ya LED. Ubwino ndi wotsimikizika, opanga amapangidwa mochuluka, ndipo mitengo yake ndi yabwino. Mphamvu ya mikanda ya nyali ya LED Magetsi osiyanasiyana amphamvu kwambiri a LED nthawi zambiri amagwiritsa ntchito mikanda ya nyale ya 1W yamphamvu yamphamvu ya LED, 1-3W imakhala yolumikizana ndi mikanda yamagetsi yamphamvu kwambiri, COB yamphamvu kwambiri izi. Ultra -mphamvu nyali mikanda single LED mphamvu akhoza kukulitsa ndi 200w kapena kuposa. Nyali yaying'ono yamphamvu ya LED nthawi zambiri imagwiritsidwa ntchito ndi mikanda yachigamba, yomwe imaphatikizapo izi: mikanda ya nyali 5050, 0.2W iliyonse, nyali 3528, 0.06W iliyonse, nyali 3014, 0.1W iliyonse, nyali 5630, chilichonse, nyali 5630, chilichonse , nyale 5630, nyale iliyonse 5630, ndi nyale 5630, nyale iliyonse 5630, ndi nyale 5630. 0.5W pa imodzi, mikanda ya nyali 5730, 0.5W iliyonse. Malinga ndi mtengo wamtengo wapatali, mtengo wa mikanda yamagetsi yamphamvu kwambiri ya LED ndi yayikulu kuposa mtengo wamagetsi otsika. Chimodzi ndi chakuti mtengo wa mkulu -mphamvu LED palokha ndi mkulu; china ndi chakuti LED yamphamvu kwambiri iyenera kuwonjezeredwa ndi masinki otentha a aluminiyamu, ndipo mphamvu yaying'ono imangofunika kugwiritsidwa ntchito ngati wamba. Circuit board, kuphatikiza kutentha kwachilengedwe kumatha kukwaniritsa zofunikira. Mphamvu yamphamvu ya LED imagwiritsidwa ntchito pazinthu zomwe zimafuna kuwala kwapamwamba m'dera la unit, monga nyali zapadenga za LED, nyali za LED, thovu la LED, magetsi a mumsewu, ndi zina zotero. Mphamvu yaying'ono ya LED imagwiritsidwa ntchito pazinthu zomwe zili ndi malo ang'onoang'ono pachigamba komanso kutentha kosakwanira. Pamafunika otsika-emitting zofunika kwa gwero kuwala m'dera unit, monga nyali denga la LED, nyali fulorosenti LED, nyali LED gulu, LED kuwala magulu Dikirani. Kwa mikanda ya nyali ya LED, ubwino wake ndi wotani? Mikanda ya nyali ya LED yayikidwa mwachindunji ndi chigamba. Ndikupita patsogolo kwaukadaulo, tchipisi tambiri ta LED totulutsa timawoneka, ndikuphatikizidwa molunjika pagawo laling'ono (mzere, kapangidwe kayenyedwe ka kutentha) Ultra -high -mphamvu zowala za LED, izi ndi “COB ”(Zikuwoneka ngati mkanda wa nyali, womwe kwenikweni ndi mikanda ya nyali). Ndipo pa chigamba, ubwino wake ndi chiyani? Integrated LED nthawi zambiri ndi dzina lina la gwero la kuwala kwa COB pamsika, koma kwenikweni, mawonekedwe a gwero la kuwala kwa COB sangathe kufotokozedwa bwino. COB imatanthawuza Chip-on-Buard, yomwe idayika mwachindunji kachipangizo kakang'ono kamphamvu ku mbale yochokera ku aluminiyamu kuti ichotse kutentha mwachangu, malo a chip ndi ang'onoang'ono, kutentha kwapang'onopang'ono ndikokwera, ndipo kuyendetsa komweko kumakhala kochepa. Chotero. Poyerekeza ndi mawonekedwe amagetsi wamba a SMD ang'onoang'ono amagetsi: kuwala kwambiri, kukana kutsika kwamafuta (
