Zithini iingenelo ze-ics ezakhelwe ngaphakathi kunye ne-ics zangaphandle kwi-LED light strips ngokulandelanayo?

Kwintsimi yeImicu yokukhanya ye-LED, umahluko ophambili phakathi kwe-"IC eyakhelwe ngaphakathi" kunye ne-"IC yangaphandle" ukwindawo yokufakela itshiphu yokulawula (IC), emisela ngokuthe ngqo imo yolawulo, iimpawu zokusebenza, ubunzima bokufakela kunye neemeko ezifanelekileyo zemigca yokukhanya. Iingenelo kunye nomahluko phakathi kwezi zimbini zinokuthelekiswa ngokucacileyo kwiinkalo ezininzi, ngolu hlobo lulandelayo:

Umcu wokukhanya we-IC owakhelwe ngaphakathi: I-IC kunye ne-LED zidibeneyo, zilula uyilo kunye nofakelo
Eyona nto iphambili kwi-IC light strip eyakhelwe ngaphakathi kukupakisha i-control chip (IC) kunye ne-LED light bead iyonke (njengeemodeli eziqhelekileyo ze-WS2812B, SK6812, njl.njl.), oko kukuthi, "i-light bead enye ihambelana ne-IC enye", ngaphandle kwesidingo se-external control chip eyongezelelweyo. Iingenelo zayo zibonakala kakhulu kwezi zinto zilandelayo:

1. Isakhiwo esincinci kunye nokufakwa okulula
I-IC eyakhelwe ngaphakathi idibanisa "ii-LED beads + i-control IC" kwiphakheji enye, nto leyo eyenza ulwakhiwo lulonke lwe-light strip lube mncinci, lube lula kwaye lube slimer. Akukho mfuneko yokubhukisha indawo eyongezelelweyo yokufakela i-IC, efanelekileyo ngakumbi kwiindawo ezimxinwa kunye neemeko ezincinci (ezifana nee-light troughs zefenitshala, izixhobo zemidlalo, kunye nezibane ezincinci zokuhombisa).
Xa uyifaka, akukho mfuneko yokulungisa i-IC yangaphandle ngokwahlukeneyo. Yincamathisele okanye uyifake ngentambo ngendlela eqhelekileyo yemigca yokukhanya, nto leyo enciphisa kakhulu ubunzima bokwakha. Kwanabaqalayo banokuyisebenzisa ngokukhawuleza.
2. Ulawulo oluhle, oluxhasa "ulawulo lombala olunenqaku elinye"
Njengoko i-LED nganye ine-IC ezimeleyo, inokufezekisa ukukhanya okuzimeleyo kunye nokulungiswa kombala wee-pixels ngazinye (ii-LED beads) (ezifana neziphumo eziguqukayo ezifana namanzi ahambayo, i-gradient, kunye nomboniso wombhalo), inika ukubonakala okucacileyo. Ifanelekile kwimiboniso efuna iziphumo zokukhanya ezicociweyo (ezifana nokukhanya okungqongileyo, ukukhanya okungasemva kwemizobo yokuhombisa, kunye nokukhanya kweenkcukacha zeqonga).
3. Ukufakelwa kwentambo okulula kunciphisa inani leendawo zokungasebenzi kakuhle
Iintambo zokukhanya ze-IC ezakhelwe ngaphakathi zihlala zifuna iingcingo ezintathu kuphela: “i-VCC (ezakhayo), i-GND (ezakhayo), kunye ne-DAT (umgca wesignali)” ukuze zisebenze (ezinye iimodeli ziquka imigca yewotshi ye-CLK), kwaye akukho mfuneko yokulungiselela umbane owongezelelweyo okanye imigca yesignali ye-ics yangaphandle. Inani leengcingo lincinci, kwaye isekethe ilula.
Ngokunciphisa "ii-nodes zonxibelelwano phakathi kwe-IC yangaphandle kunye nee-LED beads", amathuba okuba kubekho iimpazamo ezibangelwa ziintambo ezikhululekileyo kunye nonxibelelwano olubi ancitshiswa ngokwemvelo, kwaye uzinzo luphezulu.
4. Ixabiso liyalawuleka kwaye lifanelekile kwiimeko eziphakathi nezincinci
Nangona ixabiso le-"LED + eyakhelwe ngaphakathi kwi-IC" enye liphezulu kancinci kuneleebhanti zezibane eziqhelekileyo, lisusa iindleko zokuthengwa kunye nokudityaniswa kwe-ics zangaphandle, okwenza ixabiso lesisombululo lilonke lilawuleke ngakumbi. Lifaneleke ngakumbi kwiintlobo eziphakathi nezincinci kunye nobude obuphakathi nezincinci (ezifana nokuhombisa ikhaya kunye nokuhombisa okuncinci kwezorhwebo).

Umcu wokukhanya we-IC wangaphandle: I-IC ingaphandle ngokuzimeleyo, ihlengahlengisa ngokulula kwiimeko ezinamandla aphezulu nezintsonkothileyo
Uphawu oluphambili lomcu wokukhanya we-IC wangaphandle kukuba i-control chip (IC) kunye nee-LED beads zifakwe ngokwahlukeneyo – ii-beads zii-IC beads eziqhelekileyo (ezifana nee-5050, ii-2835 beads), ngelixa i-control IC ithengiswa ngokuzimeleyo kwindawo ethile kwibhodi ye-PCB yomcu wokukhanya (ezifana ne-WS2811, i-TM1914, njl.njl.) Ngokwesiqhelo, "i-IC enye ilawula ii-LED beads ezininzi" (umzekelo, i-IC enye ilawula ii-LED beads ezintathu). Iingenelo zayo zibonakala kakhulu kwezi zinto zilandelayo:

1-Iyahambelana namandla aphezulu kwaye inokusasaza ubushushu okungcono
I-IC yangaphandle yahlulwe kwiibheyi zokukhanya ze-LED, nto leyo ethintela ingxaki "yokuqokelelana kobushushu" ye-IC kunye neebheyi zokukhanya kwiphakheji enye. Ifanelekile ngokukodwa kwiibheyi zokukhanya ezinamandla aphezulu (ezifana nezo zinamandla angaphezu kwe-12W ngemitha nganye kunye neemeko zokukhanya okukhanyayo okuphezulu).
Ii-ic zangaphandle zinokususa ubushushu kwindawo enkulu yefoyile yobhedu kwibhodi ye-PCB okanye izakhiwo ezongezelelweyo zokusasaza ubushushu zinokuyilwa ukunciphisa umngcipheko wokonakala kokusebenza okanye umonakalo obangelwa ngamaqondo obushushu aphezulu. Uzinzo lwazo lwexesha elide lufanelekile ngakumbi kwizicelo zomthwalo ophezulu (ezifana nezibane zorhwebo kunye neebhokisi zezibane zentengiso zangaphandle).

2-Ulawulo oluguquguqukayo, oluxhasa "ukuhlelwa kweentsimbi zezibane ezininzi"
Ii-ics zangaphandle zihlala zixhasa "i-IC enye elawula ii-light beads ezininzi" (ezifana nezibane ezi-3/IC, izibane ezi-6/IC), kwaye zinokufikelela "kulawulo lwemibala ngokweqela" - zilungele iimeko ezineemfuno eziphantsi "zolawulo lombala wenqaku elinye" kodwa zifuna "iziphumo eziguqukayo zengingqi" (ezifana nezibane zesakhiwo sangaphandle, izibane zokuhlamba eludongeni ezinkulu).
Ezinye ii-ic zangaphandle (ezifana ne-WS2811) zixhasa ukufakelwa kwe-voltage ephezulu (ezifana ne-12V/24V). Xa kuthelekiswa nokufakwa kwe-5V okuqhelekileyo kwee-ic ezakhelwe ngaphakathi, zinokunciphisa i-voltage encinci ngexesha lokudluliselwa komgama omde kwaye zifanelekile kwizicelo ze-ultra-long light strip (ezifana nee-light strips zangaphandle ezingaphezu kweemitha ezili-10).

3-Iindleko zokulungisa eziphantsi kwaye kulula ukuzitshintsha
I-IC yangaphandle yahlulwe kwiibheyi zesibane. Ukuba i-IC ethile ayisebenzi kakuhle, yi-IC enengxaki kuphela ekufuneka itshintshwe ngokwahlukileyo, ngaphandle kwemfuneko yokutshintsha yonke i-light strip (ukuba i-IC yangaphakathi ayisebenzi kakuhle, kufuneka itshintshwe yonke iphakheji "yeebheyi zesibane + IC"). Ngokufanayo, ukuba iibheyi ze-LED azisebenzi kakuhle, akukho mfuneko yokutshintsha i-IC kunye nazo. Ngexesha lokugcinwa, iindleko zezixhobo ziphantsi kwaye ukusebenza kuyaguquguquka ngakumbi.
Kwiimeko zokusetyenziswa okukhulu kunye nexesha elide (ezifana neevenkile ezinkulu kunye neeprojekthi zangaphandle), inzuzo yeendleko zokugcinwa kamva icacile ngakumbi.

4-Ukuhambelana okunamandla, okufanelekileyo kwiinkqubo zolawulo ezintsonkothileyo
Ukukhethwa kwemodeli ye-ics yangaphandle kwahlukahlukene ngakumbi. Ezinye i-ics zangaphandle eziphezulu zixhasa amazinga aphezulu okudluliselwa kwesignali kunye neendlela zokulawula ezingaphezulu, kwaye ziyahambelana neenkqubo zolawulo ezintsonkothileyo (ezifana ne-DMX512, i-Art-Net protocol), ezifanelekileyo kwiimeko zobunjineli ezinkulu (ezifana neenkqubo zokukhanyisa isiteji, ukukhanya kwendawo enkulu), kwaye zinokufikelela kulawulo lonxibelelwano oluhambelanayo lwemigca emininzi yokukhanya.

Ukuba iimfuno zezokuba yindawo encinci, iziphumo ezintle ze-dynamic, kunye nokufakelwa okulula (njengokukhanya kwekhaya, ukuhombisa idesktop), beka phambili ekukhetheni imicu yokukhanya ye-IC eyakhelwe ngaphakathi.
Ukuba iimfuno zezombane ophezulu, umgama omde, iimeko zangaphandle okanye ukulungiswa okulula kwinqanaba lokugqibela (ezifana nezibane zezakhiwo zangaphandle kunye neevenkile ezinkulu), imicu yokukhanya ye-IC yangaphandle kufuneka inikwe ingqalelo.
Izibane ze-MX zinezibane ezahlukeneyo ze-LED strip kuquka i-COB/CSP strip,umgca we-pixel oguqukayo,i-neon flex,umcu we-voltage ephezulu kunye ne-wallwasher.Qhagamshelana nathiukuba ufuna iisampulu zovavanyo!
