Kuwunika kwa ubale pakati pa mtundu wa nyali za LED ndi mphamvu yoyendetsa

LED yakula mwachangu m'magawo osiyanasiyana ogwiritsira ntchito m'zaka zaposachedwa, chifukwa ilibe zinthu zapoizoni, ndi yogwirizana ndi chilengedwe, imakhala ndi moyo wautali wautumiki, ndipo imakhala ndi mawonekedwe apamwamba kwambiri.Mwachidziwitso, moyo wautumiki wa LED ndi pafupifupi maola 100,000, koma munjira yonse yogwiritsira ntchito, opanga ena owunikira a LELED sadziwa mokwanira za magetsi oyendetsa galimoto kapena amawagwiritsa ntchito mopanda nzeru, ndipo mapeto amafupikitsa kwambiri moyo wautumiki wa kuyatsa kwa LED. mankhwala.

Chifukwa chapadera pakupanga kwa LED, kukonza ndi kupanga, mawonekedwe amagetsi amakono ndi opangira ma LED opangidwa ndi opanga osiyanasiyana komanso ngakhale wopanga yemweyo mugulu limodzi lazinthu amasiyana kwambiri.Kutengera mtundu wa 1W kuwala koyera kwa LED ndi zitsanzo monga chitsanzo, malinga ndi kusintha kwa magetsi amakono a LED ndikugwira ntchito, zikufotokozedwa mwachidule kuti 1W kuwala koyera nthawi zambiri kumatenga mphamvu yogwira ntchito ya 3.0-3.6V.Pofuna kutsimikizira moyo wautumiki wa 1WLED, wopanga wamkulu wa LED amalimbikitsa kuti fakitale yowunikira igwiritse ntchito magetsi a 350mA kuyendetsa.Pamene kutsogolo kutsogolo kwa mbali zonse za LED kufika 350mah, kutsogolo voteji ntchito mbali zonse za LED sikungawonjezeke kwambiri, amene kwambiri kuonjezera kutsogolo panopa wa LED kuonjezera mababu LED, kupanga LED yozungulira kutentha mu mzere wofananira, potero ukufulumizitsa kuwala kwa LED.kuwonongeka, kuchepetsa moyo wautumiki wa LED.Chifukwa chapadera kwa magetsi ogwiritsira ntchito a LED ndi kusintha kwamakono, magetsi osinthika omwe amayendetsa ma LED amayendetsedwa bwino.

LED drive switching magetsi ndiye maziko a nyali za LED.Zili ngati ubongo wa munthu.Kuti apange nyali zamtundu wapamwamba wa LED, njira yoyendera magetsi yoyendetsera ma LED iyenera kusiyidwa.
Panthawiyi, zinthu zowunikira za LED zopangidwa ndi opanga ambiri (monga mipanda yoteteza, makapu a nyali, nyali zowonetsera, nyali za udzu, ndi zina zotero), sankhani zotsutsana, kuchepetsa kuthamanga kwa magazi, ndikuwonjezera chubu cha Zener diode Zener ku mphamvu ya LED. dongosolo loperekera, kuti apititse patsogolo ma LED Njirayi ili ndi zovuta zazikulu, choyamba, ndiyopanda ntchito, imawononga mphamvu zambiri zamagetsi pamagetsi otsika, ndipo imatha kupitilira mphamvu yamagetsi yomwe imagwiritsidwa ntchito ndi ma LED, ndipo sangathe. kuyendetsa mafunde akuluakulu.Chifukwa chapamwamba chamakono, mphamvu zambiri zimatayidwa pazitsulo zotsika pansi, palibe chitsimikizo chakuti magetsi a LED sangapitirire muyeso wake wamba.Mukapanga chinthu, kusankha kuchepetsa ma voliyumu awiri a DC a LED kuti muyendetse makina opangira magetsi ndiye mwayi waukulu wosiya chromaticity ya LED.Sankhani kukana, njira yochepetsera kuthamanga kwa magazi kukankhira LED, kuwala kwa skrini kwa LED sikungakhale kokhazikika.Mphamvu yamagetsi yamagetsi yamagetsi ikatsika, chromaticity ya LED imakhala yakuda, ndipo mphamvu yamagetsi yamagetsi yamagetsi ikakwera, chromaticity ya LED ndi yayikulu, ndipo chromaticity ya LED ndi apamwamba.Mwachibadwa, njira yochepetsera kuthamanga kwa magazi ndiyo mwayi waukulu wochepetsera mtengo wamtengo wapatali.
