Chitchaina
Mu gawo laZingwe zowunikira za LED, kusiyana kwakukulu pakati pa "IC yomangidwa mkati" ndi "IC yakunja" kuli pamalo oyikapo chipangizo chowongolera (IC), chomwe chimatsimikizira mwachindunji momwe chipangizocho chimagwirira ntchito, mawonekedwe ake, zovuta zomwe zimagwiritsidwa ntchito, komanso zochitika zomwe zimagwiritsidwa ntchito pazigawo zowunikira. Ubwino ndi kusiyana pakati pa ziwirizi kumatha kuyerekezeredwa bwino kuchokera kumitundu yosiyanasiyana, motere:
Mzere wowala wa IC womangidwa mkati: IC ndi LED zophatikizidwa, zomwe zimapangitsa kuti kapangidwe ndi kuyika zikhale zosavuta
Mbali yaikulu ya mzere wowala wa IC womangidwa mkati mwake ndikuyika chipu chowongolera (IC) ndi mkanda wa LED wonse (monga mitundu yodziwika bwino ya WS2812B, SK6812, ndi zina zotero), kutanthauza kuti, "mkanda umodzi wowala umagwirizana ndi IC imodzi", popanda kufunikira chipu chowonjezera chakunja chowongolera. Ubwino wake umaonekera makamaka m'mbali zotsatirazi:
1. Kapangidwe kakang'ono komanso kosavuta kukhazikitsa
IC yomangidwa mkati imaphatikiza "mikanda ya LED + IC yolamulira" mu phukusi limodzi, zomwe zimapangitsa kuti kapangidwe kake ka mzere wowala kakhale kopyapyala, kopepuka komanso kosalala. Palibe chifukwa chosungira malo owonjezera kuti muyike IC, yomwe ndi yoyenera makamaka Malo opapatiza komanso zochitika zazing'ono (monga malo owunikira mipando, zolumikizira zamagetsi, ndi magetsi ang'onoang'ono okongoletsera).
Mukakhazikitsa, palibe chifukwa chokonzera IC yakunja padera. Ingoikani kapena ikani waya m'njira yachizolowezi ngati mizere yowala, zomwe zimachepetsa kwambiri zovuta za kapangidwe kake. Ngakhale oyamba kumene amatha kuigwiritsa ntchito mwachangu.
2. Kuwongolera bwino, kothandizira "kulamulira mtundu wa mfundo imodzi"
Popeza mkanda uliwonse wa LED uli ndi IC yodziyimira payokha, imatha kupanga kuwala kodziyimira payokha komanso kusintha mitundu ya ma pixel (mikanda ya LED) (monga zotsatira zosinthika monga madzi oyenda, gradient, ndi mawonekedwe a zolemba), zomwe zimapangitsa kuti ziwoneke bwino kwambiri. Ndi yoyenera pazithunzi zomwe zimafuna kuwala kowoneka bwino (monga kuwala kozungulira, kuwala kwa kumbuyo kwa zojambula zokongoletsera, ndi kuunikira kwatsatanetsatane wa siteji).
3. Kulumikiza mawaya kosavuta kumachepetsa kuchuluka kwa malo olakwika
Zingwe zoyatsira magetsi za IC zomwe zimamangidwa mkati nthawi zambiri zimafuna mawaya atatu okha: “VCC (positive), GND (negative), ndi DAT (signal line)” kuti zigwire ntchito (mitundu ina imaphatikizapo mizere ya wotchi ya CLK), ndipo palibe chifukwa chokonzera magetsi owonjezera kapena mizere ya chizindikiro cha ma ics akunja. Chiwerengero cha mawaya ndi chochepa, ndipo dera ndi losavuta.
Mwa kuchepetsa "ma node olumikizirana pakati pa IC yakunja ndi mikanda ya LED", mwayi wa zolakwika zomwe zimachitika chifukwa cha mawaya otayirira komanso kukhudzana kosayenera umachepetsedwa mwachibadwa, ndipo kukhazikika kumakhala kwakukulu.
4. Mtengo wake ndi wosavuta kulamulira ndipo ndi woyenera pazochitika zapakati ndi zazing'ono
Ngakhale mtengo wa "LED + IC yomangidwa mkati" imodzi ndi wokwera pang'ono kuposa wa mikanda ya nyali wamba, umachotsa mtengo wosiyana wogulira ndi kusungunula wa ma ics akunja, zomwe zimapangitsa kuti mtengo wonse wa yankho ukhale wosavuta kulamulira. Ndiwoyenera makamaka pa ntchito zapakati ndi zazing'ono komanso zapakati ndi zazing'ono (monga kukongoletsa nyumba ndi kukongoletsa pang'ono kwamalonda).
Mzere wa kuwala wa IC wakunja: IC ndi yakunja yokha, yosinthasintha kuti igwirizane ndi zochitika zamphamvu komanso zovuta
Mbali yaikulu ya mzere wa kuwala wakunja wa IC ndikuti chipu chowongolera (IC) ndi mikanda ya LED zimayikidwa padera - mikanda ndi mikanda yanthawi zonse ya IC (monga mikanda 5050, 2835), pomwe IC yowongolera imagulitsidwa payokha pamalo enaake pa bolodi la PCB la mzere wowala (monga WS2811, TM1914, ndi zina zotero). Kawirikawiri, "IC imodzi imalamulira mikanda ingapo ya LED" (mwachitsanzo, IC imodzi imalamulira mikanda itatu ya LED). Ubwino wake umaonekera makamaka m'mbali zotsatirazi:
1-Imagwirizana ndi mphamvu zambiri ndipo imachotsa kutentha bwino
IC yakunja imalekanitsidwa ndi mikanda ya kuwala ya LED, kupewa vuto la "kusonkhanitsa kutentha" kwa IC ndi mikanda yowala mu phukusi lomwelo. Ndi yoyenera makamaka mikanda ya kuwala yamphamvu kwambiri (monga yomwe ili ndi mphamvu yoposa 12W pa mita imodzi ndi zochitika zowunikira zowala kwambiri).
Ma ics akunja amatha kutulutsa kutentha kudzera m'dera lalikulu la zojambulazo zamkuwa pa bolodi la PCB kapena mapangidwe ena owonjezera otulutsa kutentha angapangidwe kuti achepetse chiopsezo cha kuwonongeka kwa magwiridwe antchito kapena kuwonongeka komwe kumachitika chifukwa cha kutentha kwambiri. Kukhazikika kwawo kwa nthawi yayitali ndikoyenera kwambiri pakugwiritsa ntchito zinthu zambiri (monga magetsi amalonda ndi mabokosi amagetsi otsatsa akunja).
2-Kulamulira kosinthasintha, komwe kumathandiza "kugawa mikanda ya nyali zambiri"
Ma ics akunja nthawi zambiri amathandizira "IC imodzi yolamulira mikanda yambiri yowala" (monga magetsi atatu/IC, magetsi 6/IC), ndipo amatha "kulamulira mitundu ndi gulu" - yoyenera zochitika zomwe zili ndi zofunikira zochepa pa "kulamulira mitundu ya malo amodzi" koma zimafuna "zotsatira zamphamvu zachigawo" (monga magetsi owonetsera nyumba zakunja, magetsi ochapira makoma akuluakulu).
Ma ic ena akunja (monga WS2811) amathandizira ma input okwera kwambiri (monga 12V/24V). Poyerekeza ndi ma input wamba a 5V a ma ic omangidwa mkati, ali ndi kuchepa kwa mphamvu yamagetsi kochepa panthawi yotumizira kutali ndipo ndi oyenera kugwiritsa ntchito ma light strips aatali kwambiri (monga ma light strips akunja opitilira mamita 10).
3-Ndalama zochepa zokonzera komanso zosavuta kusintha
IC yakunja imalekanitsidwa ndi mikanda ya nyali. Ngati IC ina yalephera, IC yolakwika yokha ndiyo iyenera kusinthidwa padera, popanda kufunikira kusintha mzere wonse wa nyali (ngati IC yamkati yalephera, phukusi lonse la "mikanda ya nyali + IC" liyenera kusinthidwa). Mofananamo, ngati mikanda ya LED yalephera, palibe chifukwa chosinthira IC pamodzi nawo. Pakukonza, mtengo wa zigawo zake ndi wotsika ndipo ntchitoyo imakhala yosinthasintha.
Pazinthu zazikulu komanso zazitali zomwe zimagwiritsidwa ntchito (monga m'masitolo akuluakulu ndi mapulojekiti akunja), phindu la kukonza pambuyo pake ndi lodziwikiratu.
4-Kugwirizana kwamphamvu, koyenera machitidwe ovuta owongolera
Kusankha kwa ma ics akunja kwa mitundu yosiyanasiyana kumakhala kosiyanasiyana. Ma ics ena apamwamba akunja amathandizira kufalikira kwa ma signal ambiri komanso njira zambiri zowongolera, ndipo amagwirizana ndi machitidwe ovuta owongolera (monga DMX512, Art-Net protocol), oyenera zochitika zazikulu zaukadaulo (monga machitidwe oyatsa pasiteji, kuyatsa kwakukulu kwa malo), ndipo amatha kukwaniritsa kuwongolera kulumikizana kwa mizere yambiri ya kuwala.
Ngati zofunikira ndi malo ochepa, mphamvu zochepa, komanso kuyika kosavuta (monga magetsi ozungulira nyumba, kukongoletsa kompyuta), perekani patsogolo kusankha mipiringidzo ya magetsi ya IC yomangidwa mkati.
Ngati zofunikira ndi za mphamvu zambiri, mtunda wautali, zochitika zakunja kapena kukonza kosavuta pambuyo pake (monga nyumba zakunja ndi magetsi a m'masitolo), mizere ya magetsi akunja a IC iyenera kuperekedwa patsogolo.
Kuwala kwa MX kuli ndi magetsi osiyanasiyana a LED kuphatikizapo COB/CSP strip,mzere wa ma pixel wamphamvu,neon flex, chingwe chamagetsi champhamvu komanso chotsukira khoma.Lumikizanani nafengati mukufuna zitsanzo zoyesera!
