High-power White Light LED Street Light Light Light Light Board Design ndi Driving Technology

Pofuna kukulitsa kuchuluka kwa kutembenuka kwa magetsi komanso kutentha kwapang'onopang'ono kwa matabwa owunikira magetsi a mumsewu, mapangidwe a tchipisi ta LED amagwiritsidwa ntchito kukulitsa madera a tchipisi ta LED, ndipo ukadaulo wa electrode optimization kuchuluka kwa tchipisi ta LED. , Pangani chip pamwamba kutentha kumayenda mofanana, ntchito ya chip imakhala yokhazikika. Kuwunika kwa kuyika kwa ma LED opepuka amphamvu kwambiri kuti apititse patsogolo kuwunikira kwa chip, kutsimikizira kuwala koyera, komanso ukadaulo wochotsa kutentha kwa chipangizocho. Kutengera zotsatira zaukadaulo womwe uli pamwambapa komanso pulogalamu yowunikira zinthu zomaliza pazotsatira zowunikira kukana kwamphamvu kwapang'onopang'ono kwa zida za LED, ukadaulo wophatikizira wa COB (Chip On Board) LED chip idatsimikiza kuti ipanga njira yabwino kwambiri yothetsera vutoli. kupanga matabwa ounikira mumsewu wa LED. Kutentha kwa chip mfundo za LED ndikosavuta kuwongolera pansi pa 120 C, komanso kumagwirizana bwino ndi ukadaulo wakunja wakutulutsa kutentha. Mtunda wabwino kwambiri pakati pa LED high -power chip array chip unawerengeredwa kudzera munjira yabwino kwambiri yochirikiza masamu ya kuwala. Pomaliza, poyerekezera njira zosiyanasiyana zoyatsira magetsi a LED, njira yabwino kwambiri yoyendetsera nyali yoyera ya LED imatsimikiza kusintha kuwala kwa mitsempha yayikulu yapano (PWM). Pakalipano, nyali zochulukirachulukira za LED zalowa m'malo mwa nyali zachikhalidwe, ndipo zimagwiritsidwa ntchito powonetsera kuyatsa, kuyatsa malonda, kuyatsa pansi pa madzi, kuunikira kwa zomangamanga, magetsi a pamsewu ndi ntchito zina. Boma lathu lakhala “Kuteteza mphamvu ”Monga ndondomeko ya dziko. Ndi dziko “Kuteteza mphamvu ”Ntchitoyi ikuchitika mozama, “Green Lighting Engineering ”Zalembedwa ngati projekiti yofunikira kwambiri m'dziko langa komanso njira yazaka zana zamafakitale opulumutsa mphamvu. Makampani opanga zowunikira ku China alowa m'malo okweza mafakitale. Pankhani yoyitanitsa kusungitsa mphamvu zowunikira ndikuchepetsa mpweya, zida za LED zogwiritsa ntchito bwino kwambiri komanso zopulumutsa mphamvu ndizofunikira pakukweza mafakitale. “Chiyambi cha kusintha kwatsopano m'munda wowunikira ”Zimaphatikiza zabwino zambiri monga kutetezedwa kwa chilengedwe, moyo wautali, kupulumutsa mphamvu kwamphamvu, kutulutsa mitundu yambiri, kuthwanima kosachitika pafupipafupi, cheza chosakhala cha ultraviolet, udzudzu wopanda udzudzu, kuyambika nthawi yomweyo, kuchuluka kwa ntchito yamagetsi, kutentha kwakukulu kogwira ntchito ndi zina. ubwino. Ubwino wa chitetezo cha chilengedwe ndi mtsogoleri wa zinthu zowunikira zopulumutsa mphamvu. Ngati 10% ya kuwala kwachikhalidwe m'dziko langa asinthidwa ndi LED chaka chilichonse, akhoza kupulumutsa 9 biliyoni kWh, yomwe ndi yofanana ndi matani 8.64 miliyoni a carbon dioxide. Pakadali pano, zida zowunikira nyali zamphamvu za LED zalowanso m'mbali zonse za moyo wa anthu. Zotsatirazi ndi nyali zochepa zomwe zimagwiritsidwa ntchito, poyerekeza ndi nyali za LED kuti muyese ubwino wa nyali za LED. Nyali za LED zimapindula poyerekezera ndi tebulo lochulukira (magetsi amalonda: 1.2 yuan/kWh) Jinghan Optoelectronics anakambirana nanu za ubwino wa nyali za LED mu kusintha kopulumutsa mphamvu ndi tebulo pamwambapa. Kugwiritsa ntchito. Kwa nyali yamakono yopulumutsa mphamvu kapena nyali ya dzuwa, mphamvu yopulumutsira mphamvu ndi yoposa 50%, ndipo zinthu zovulaza ndi zakupha mu nyali yopulumutsa mphamvu kapena chubu cha dzuwa zimapewedwa. —— HG. Kuphwanyidwa kwa chubu cha nyali ya 36W kungayambitse mpweya wa mercury mumlengalenga wozungulira kupitirira nthawi 2000 muyeso wa dziko; ndipo nyali zina zazing'ono sizisamalidwa bwino, komanso mercury yomwe ili pansi pa nthaka. Ndizovuta kwambiri ku chilengedwe. Kuwala kwa LED sikungangoyang'anizana ndi vuto lamphamvu lamphamvu, komanso kupereka njira yofunikira yoyeretsera chilengedwe. Chifukwa chake, kuthekera kwa kuyatsa kwa LED pakusintha kopulumutsa mphamvu ndi kwakukulu.
