Emkhakheni we-Imichilo yokukhanya ye-LED, umehluko oyinhloko phakathi kwe-“IC eyakhelwe ngaphakathi” kanye ne-“IC yangaphandle” usesikhundleni sokufakwa kwe-chip yokulawula (i-IC), enquma ngqo imodi yokulawula, izici zokusebenza, ubunzima bokufaka kanye nezimo ezisebenzayo zemichilo yokukhanya. Izinzuzo nomehluko phakathi kwalokhu okubili kungaqhathaniswa ngokucacile kusuka ezilinganisweni eziningi, kanje:
Umugqa wokukhanya we-IC owakhelwe ngaphakathi: I-IC ne-LED ezihlanganisiwe, okwenza kube lula ukuklama nokufaka
Isici esiyinhloko somugqa wokukhanya we-IC owakhelwe ngaphakathi ukupakisha i-chip yokulawula (i-IC) kanye ne-bead yokukhanya ye-LED iyonke (njengamamodeli avamile i-WS2812B, i-SK6812, njll.), okungukuthi, "i-bead eyodwa yokukhanya ihambisana ne-IC eyodwa", ngaphandle kwesidingo se-chip yokulawula yangaphandle eyengeziwe. Izinzuzo zayo zibonakala kakhulu kulezi zici ezilandelayo:
1. Isakhiwo esincane kanye nokufakwa okulula
I-IC eyakhelwe ngaphakathi ihlanganisa “ama-LED beads + i-control IC” ephaketheni elilodwa, okwenza isakhiwo sonke somugqa wokukhanya sibe sincane, silula futhi sibe bushelelezi. Asikho isidingo sokubhukha isikhala esengeziwe sokufakwa kwe-IC, okufanelekela kakhulu izikhala ezincane nezimo ezincane (njengezibani zefenisha, izinto zemidlalo, kanye nezibani ezincane zokuhlobisa).
Uma ufaka, asikho isidingo sokulungisa i-IC yangaphandle ngokwehlukana. Vele uyinamathisele noma uyifake ngocingo ngendlela evamile yemichilo yokukhanya, okunciphisa kakhulu ubunzima bokwakhiwa. Ngisho nabaqalayo bangayisebenzisa ngokushesha.
2. Ukulawula okuhle, okusekela "ukulawula umbala wephuzu elilodwa"
Njengoba ubhontshisi ngamunye we-LED uhlonyiswe nge-IC ezimele, ungafinyelela ukukhanya okuzimele kanye nokulungiswa kombala kwamaphikseli ngamanye (ubhontshisi be-LED) (njengemiphumela eguquguqukayo efana namanzi agelezayo, i-gradient, kanye nokuboniswa kombhalo), okuhlinzeka ngokubonakala okucebile. Ifanele izigcawu ezidinga imiphumela yokukhanya ecwengekile (njengokukhanya okuzungezile, ukukhanya kwangemuva kwemidwebo yokuhlobisa, kanye nokukhanya kwemininingwane yesiteji).
3. Ukuxhuma izintambo okulula kunciphisa inani lamaphuzu okwehluleka
Imichilo yokukhanya ye-IC eyakhelwe ngaphakathi ivame ukudinga izintambo ezintathu kuphela: “i-VCC (enhle), i-GND (engembi), kanye ne-DAT (umugqa wesiginali)” ukuze isebenze (amanye amamodeli afaka imigqa yewashi le-CLK), futhi asikho isidingo sokuhlela ukunikezwa kwamandla okwengeziwe noma imigqa yesiginali yama-ics angaphandle. Inani lezintambo lincane, futhi isekethe ilula.
Ngokunciphisa "ama-node okuxhumana phakathi kwe-IC yangaphandle kanye nama-LED beads", amathuba okuba nezinkinga ezibangelwa ukuxhuma okuxekethile kanye nokuxhumana okungekuhle ancishiswa ngokwemvelo, futhi ukuzinza kuphakeme.
4. Izindleko ziyalawuleka futhi zifanele izimo eziphakathi nendawo nezincane
Nakuba izindleko ze-“LED + i-IC eyakhelwe ngaphakathi” eyodwa ziphakeme kancane kunezobuhlalu bezibani ezivamile, zisusa izindleko zokuthengwa nokushiswa ezihlukene zama-ics angaphandle, okwenza izindleko zesisombululo zilawuleke kakhudlwana. Zifaneleka kakhulu ekusetshenzisweni kweqoqo eliphakathi nelincane kanye neliphakathi nelincane (njengokuhlobisa ikhaya kanye nokuhlobisa okuncane kwezentengiselwano).
Umugqa wokukhanya we-IC wangaphandle: I-IC ingaphandle ngokuzimela, ivumelana nezimo nezimo ezinamandla aphezulu neziyinkimbinkimbi
Isici esiyinhloko somugqa wokukhanya we-IC wangaphandle ukuthi i-control chip (IC) kanye nama-LED beads kufakwe ngokwehlukana – ama-beads angama-IC beads ajwayelekile (njenge-5050, ama-beads angu-2835), kuyilapho i-control IC ihlanganiswe ngokuzimela endaweni ethile ebhodini le-PCB lomugqa wokukhanya (njenge-WS2811, i-TM1914, njll.) Ngokuvamile, “i-IC eyodwa ilawula ama-LED beads amaningi” (isibonelo, i-IC eyodwa ilawula ama-LED beads amathathu). Izinzuzo zayo zibonakala kakhulu kulezi zici ezilandelayo:
1-Iyahambisana namandla aphezulu futhi inokushisa okungcono
I-IC yangaphandle ihlukaniswe nama-LED light beads, igwema inkinga "yokuqongelela ukushisa" kwe-IC nama-light beads ephaketheni elifanayo. Ifaneleka kakhulu kuma-light strips anamandla amakhulu (njengalawo anamandla angaphezu kuka-12W ngemitha kanye nezimo zokukhanya okukhanyayo okuphezulu).
Ama-ic angaphandle angakhipha ukushisa endaweni enkulu ye-foil yethusi ebhodini le-PCB noma izakhiwo ezengeziwe zokushabalalisa ukushisa zingaklanywa ukunciphisa ingozi yokuwohloka kokusebenza noma umonakalo obangelwa amazinga okushisa aphezulu. Ukuqina kwazo kwesikhathi eside kufaneleka kakhulu ekusetshenzisweni kwemithwalo ephezulu (njengokukhanyisa kwezentengiselwano namabhokisi okukhanya okukhangisa angaphandle).
2-Ukulawula okuguquguqukayo, okusekela "ukuhlanganiswa kwama-bead amaningi"
Ama-ic angaphandle avame ukusekela "i-IC eyodwa elawula ubuhlalu bokukhanya obuningi" (njengezibani ezi-3/IC, izibani ezi-6/IC), futhi angafinyelela "ukulawulwa kombala ngeqembu" - afanele izimo ezinezidingo eziphansi "zokulawulwa kombala wephuzu elilodwa" kodwa adinga "imiphumela eguquguqukayo yesifunda" (njengezibani zomklamo wesakhiwo sangaphandle, izibani zokugeza udonga ezinkulu).
Amanye ama-ic angaphandle (njenge-WS2811) asekela okokufaka kwe-voltage ephezulu (njenge-12V/24V). Uma kuqhathaniswa nokokufaka okuvamile kwe-5V kwama-ic akhelwe ngaphakathi, anokunciphisa i-voltage okuncane ngesikhathi sokudlulisa ibanga elide futhi afanele ukusetshenziswa kwe-strip yokukhanya ende kakhulu (njenge-strip yokukhanya yangaphandle engaphezu kwamamitha ayi-10).
3-Izindleko zokulungisa eziphansi futhi kulula ukuzishintsha
I-IC yangaphandle ihlukaniswe nama-lamp beads. Uma i-IC ethile ingasebenzi kahle, i-IC enephutha kuphela edinga ukushintshwa ngokwehlukana, ngaphandle kwesidingo sokushintsha yonke i-light strip (uma i-IC yangaphakathi ingasebenzi kahle, lonke iphakethe "lama-lamp beads + IC" lidinga ukushintshwa). Ngokufanayo, uma ama-LED beads engasebenzi kahle, asikho isidingo sokushintsha i-IC kanye nawo. Ngesikhathi sokulungiswa, izindleko zezingxenye ziphansi futhi ukusebenza kuyaguquguquka.
Ezimweni zokusetshenziswa okukhulu nesikhathi eside (njengezitolo ezinkulu kanye namaphrojekthi angaphandle), inzuzo yezindleko zokulungiswa kamuva isobala kakhulu.
4-Ukuhambisana okuqinile, okufanele izinhlelo zokulawula eziyinkimbinkimbi
Ukukhethwa kwamamodeli ama-ic angaphandle kuhlukahlukene kakhulu. Amanye ama-ic angaphandle aphezulu asekela amazinga aphezulu okudlulisa isignali kanye neziteshi zokulawula eziningi, futhi ayahambisana nezinhlelo zokulawula eziyinkimbinkimbi (njenge-DMX512, iphrothokholi ye-Art-Net), ezifanele izimo zobunjiniyela obukhulu (njengezinhlelo zokukhanyisa esiteji, ukukhanyisa indawo enkulu), futhi angafinyelela ukulawulwa kokuxhumanisa okuhambisanayo kwemichilo eminingi yokukhanya.
Uma izidingo zingezesikhala esincane, imiphumela emihle eguquguqukayo, kanye nokufakwa okulula (njengokukhanyisa kwekhaya, ukuhlobisa ideskithophu), nikeza kuqala ukukhetha imichilo yokukhanya ye-IC eyakhelwe ngaphakathi.
Uma izidingo zingezamandla aphezulu, ibanga elide, izimo zangaphandle noma ukulungiswa okulula esigabeni esilandelayo (njengokukhanyisa kwesakhiwo sangaphandle kanye nezitolo ezinkulu), imichilo yokukhanya ye-IC yangaphandle kufanele inikezwe kuqala.
Ukukhanya kwe-MX kunezibani ze-LED ezahlukahlukene okuhlanganisa i-COB/CSP strip,umugqa wephikseli onamandla,i-neon flex,i-strip ye-voltage ephezulu kanye ne-washer yodonga.Xhumana nathiuma udinga amasampula okuhlolwa!
