Chitchainizi
M'munda waZowunikira za LED, kusiyana kwakukulu pakati pa "IC yomangidwa" ndi "IC yakunja" ili pa malo oyika chipangizo chowongolera (IC), chomwe chimatsimikizira mwachindunji njira yoyendetsera, mawonekedwe ogwirira ntchito, zovuta zoikamo ndi zochitika zomwe zimagwiritsidwa ntchito pazitsulo zowunikira. Ubwino ndi kusiyana pakati pa ziwirizi zitha kufananizidwa momveka bwino kuchokera kumagulu angapo, motere:
Mzere wowala wa IC womangidwa: IC ndi LED zophatikizika, zophweka kupanga ndi kukhazikitsa
Chofunikira kwambiri pamizere yowunikira ya IC ndikuyika chipangizo chowongolera (IC) ndi mkanda wowunikira wa LED wonse (monga mitundu wamba WS2812B, SK6812, etc.), ndiye kuti, "mkanda umodzi wowala umafanana ndi IC imodzi", popanda kufunikira kwa chipangizo china chowongolera kunja. Ubwino wake umawonekera makamaka muzinthu izi:
1.Mapangidwe a Compact ndi kukhazikitsa kosavuta
IC yomangidwira imaphatikiza "mikanda ya LED + yowongolera IC" mu phukusi limodzi, kupangitsa mawonekedwe onse a mzere wowala kukhala woonda, wopepuka komanso wocheperako. Palibe chifukwa chosungira malo owonjezera kuti akhazikitse IC, yomwe ili yoyenera kwambiri Malo ocheperako komanso mawonekedwe ang'onoang'ono (monga mabwalo amipando, zotumphukira zamasewera, ndi magetsi okongoletsa ang'onoang'ono).
Mukayika, palibe chifukwa chokonzekera IC yakunja padera. Ingomamatirani kapena waya munjira yodziwika bwino ya mizere yopepuka, yomwe imachepetsa kwambiri zovuta zomanga. Ngakhale oyamba kumene amatha kuyigwiritsa ntchito mwachangu.
2. Kuwongolera bwino, kuthandizira "kuwongolera mtundu wamtundu umodzi"
Monga mkanda uliwonse wa LED uli ndi IC yodziyimira pawokha, imatha kuwunikira kodziyimira payokha komanso kusintha kwamitundu ya ma pixel (mikanda ya LED) (monga zosinthika monga madzi oyenda, gradient, ndi mawonetsedwe alemba), kupereka mawonekedwe owoneka bwino. Ndi yoyenera pazithunzi zomwe zimafuna kuyatsa bwino (monga kuyatsa kozungulira, kuyatsanso kwazojambula zokongoletsa, ndi kuyatsa tsatanetsatane wa siteji).
3. Wiring yosavuta imachepetsa chiwerengero cha zolakwika
Mizere yowunikira ya IC yomangidwa nthawi zambiri imafunikira mawaya atatu okha: "VCC (positive), GND (negative), ndi DAT (mzere wamakina)" kuti agwire ntchito (zitsanzo zina zimaphatikizapo mizere ya wotchi ya CLK), ndipo palibe chifukwa chokonzekera magetsi owonjezera kapena mizere yolumikizira ma ics akunja. Chiwerengero cha mawaya ndi ochepa, ndipo dera ndilosavuta.
Pochepetsa "magawo olumikizirana pakati pa IC yakunja ndi mikanda ya LED", kuthekera kwa zolakwika zomwe zimayambitsidwa ndi mawaya otayirira komanso kulumikizidwa koyipa zimatsitsidwa mwachilengedwe, ndipo kukhazikika kumakhala kokwera.
4. Mtengo wake ndi wowongoka ndipo ndi woyenera pazochitika zapakatikati ndi zazing'ono
Ngakhale mtengo wa "LED + yomangidwa mu IC" imodzi ndi yokwera pang'ono kuposa mikanda wamba wamba, imachotsa ndalama zogulira ndi zogulitsira za ma ic akunja, zomwe zimapangitsa kuti njira yonseyi ikhale yotsika mtengo. Ndizoyenera makamaka kwapakati ndi zazing'ono zazitali komanso zazing'ono ndi zazing'ono zamagulu (monga zokongoletsera kunyumba ndi zokongoletsera zazing'ono zamalonda).
Mzere wowala wa IC wakunja: IC ndi yodziyimira payokha, yosinthika yosinthika kuti ikhale yamphamvu kwambiri komanso zovuta.
Mbali yaikulu ya mzere wa kuwala kwa IC ndi chakuti chipangizo chowongolera (IC) ndi mikanda ya LED imayikidwa padera - mikanda ndi mikanda wamba ya IC (monga 5050, 2835 mikanda), pamene IC yolamulira imagulitsidwa pawokha pamalo enaake pa bolodi la PCB la mzere wowala (monga WS2811ICs, etc. mikanda ya LED” (mwachitsanzo, IC imodzi imawongolera mikanda itatu ya LED). Ubwino wake umawonekera makamaka muzinthu izi:
1-Zimagwirizana ndi mphamvu zambiri ndipo zimakhala ndi kutentha kwabwinoko
IC yakunja imasiyanitsidwa ndi mikanda ya kuwala kwa LED, kupeŵa vuto la "kutentha" kwa IC ndi mikanda yowala mu phukusi lomwelo. Ndizoyenera kwambiri zopangira zowunikira zamphamvu kwambiri (monga zomwe zili ndi mphamvu yopitilira 12W pa mita ndi mawonekedwe owunikira kwambiri).
Ma ics akunja amatha kutulutsa kutentha kudzera m'dera lalikulu la zojambula zamkuwa pa bolodi la PCB kapena zowonjezera zowonjezera kutentha zimatha kupangidwa kuti zichepetse chiopsezo cha kuwonongeka kwa ntchito kapena kuwonongeka komwe kumachitika chifukwa cha kutentha kwambiri. Kukhazikika kwawo kwanthawi yayitali kumakhala koyenera kwambiri pamapulogalamu apamwamba (monga kuunikira kwamalonda ndi mabokosi owunikira otsatsa akunja).
2-Kuwongolera kosinthika, kuthandizira "magulu a mikanda yambiri"
Ma ic akunja nthawi zambiri amathandizira "IC imodzi yolamulira mikanda yambiri yowunikira" (monga 3 magetsi / IC, 6 magetsi / IC), ndipo imatha kukwaniritsa "kuwongolera mitundu ndi gulu" - yoyenera pazochitika zomwe zili ndi zofunikira zochepa za "kuwongolera mtundu wamtundu umodzi" koma zimafunika "zotsatira zachigawo" (monga magetsi owonetsera nyumba zakunja, magetsi ochapa m'dera lalikulu).
Ma ic ena akunja (monga WS2811) amathandizira ma voliyumu apamwamba (monga 12V/24V). Poyerekeza ndi ma 5V wamba a ma ic omangidwa, ali ndi mphamvu zochepa zochepetsera magetsi pakadutsa mtunda wautali ndipo ndi oyenera kugwiritsa ntchito mizere yowunikira kwambiri (monga mizere yowala panja yopitilira 10 metres).
3-Ndalama zotsika mtengo komanso zosavuta kusintha
IC yakunja imasiyanitsidwa ndi mikanda ya nyali. Ngati vuto lina la IC silikuyenda bwino, IC yokhayo yolakwika iyenera kusinthidwa padera, popanda kufunika kosintha mzere wonse wa kuwala (ngati mkati mwa IC sagwira ntchito bwino, phukusi lonse la "lamp beads + IC" liyenera kusinthidwa). Mofananamo, ngati mikanda ya LED ikulephera, palibe chifukwa chosinthira IC pamodzi nawo. Panthawi yokonza, mtengo wa zigawozo ndi wotsika ndipo ntchitoyo imakhala yosinthika.
Pazochitika zazikulu komanso zogwiritsira ntchito nthawi yayitali (monga malo ogulitsira ndi ntchito zakunja), kupindula kwa mtengo wa kukonza pambuyo pake kumawonekera kwambiri.
4-Kugwirizana kwamphamvu, koyenera machitidwe owongolera ovuta
Kusankhidwa kwachitsanzo kwa ma ic akunja ndikosiyana kwambiri. Ma ic ena apamwamba akunja amathandizira ma mayendedwe apamwamba otumizira ma siginecha ndi njira zowongolera zambiri, ndipo amagwirizana ndi machitidwe owongolera ovuta (monga DMX512, Art-Net protocol), oyenera zochitika zazikulu zaumisiri (monga machitidwe owunikira siteji, kuyatsa kwakukulu kwa malo), ndipo amatha kukwaniritsa kuwongolera kolumikizana kolumikizana kwa mikwingwirima yambiri yowala.
Ngati zofunika ndi malo ang'onoang'ono, zowoneka bwino, ndikuyika kosavuta (monga kuyatsa kwapanyumba, kukongoletsa pakompyuta), perekani patsogolo kusankha mizere yowunikira ya IC.
Ngati zofunikira zili zamphamvu kwambiri, mtunda wautali, zochitika zakunja kapena kukonza kosavuta pambuyo pake (monga nyumba zakunja ndi kuyatsa kwa malo ogulitsira), mizere yakunja ya IC iyenera kuperekedwa patsogolo.
Kuunikira kwa MX kumakhala ndi kuwala kosiyanasiyana kwa LED kuphatikiza Mzere wa COB / CSP,dynamic pixel strip, neon flex, mizere yayikulu yamagetsi ndi wawasher.Lumikizanani nafengati mukufuna zitsanzo zoyesa!
