Igishinwa
Mu murima waLED amatara, itandukaniro ryibanze hagati ya "yubatswe muri IC" na "IC yo hanze" iri mumwanya wo kwishyiriraho chip igenzura (IC), igena mu buryo butaziguye uburyo bwo kugenzura, ibiranga imikorere, ibintu bigoye kwishyiriraho hamwe nibishobora gukoreshwa kumurongo wumucyo. Ibyiza nibitandukaniro hagati yabyo birashobora kugereranywa neza uhereye kubipimo byinshi, nkibi bikurikira:
Yubatswe muri IC yumucyo: IC na LED byahujwe, koroshya igishushanyo nogushiraho
Ikintu nyamukuru kiranga urumuri rwubatswe muri IC ni ugupakira chip igenzura (IC) hamwe nisaro rya LED muri rusange (nkicyitegererezo rusange WS2812B, SK6812, nibindi), ni ukuvuga, "isaro rimwe ryumucyo rihuye na IC imwe", bitabaye ngombwa ko hiyongeraho chip yo kugenzura hanze. Ibyiza byayo bigaragarira cyane cyane mubice bikurikira:
1.Imiterere yoroheje hamwe nogushiraho byoroshye
Muri IC yubatswe ihuza "amasaro ya LED + igenzura IC" muri paki imwe, bigatuma imiterere rusange yumurongo wumucyo yoroshye, yoroshye kandi yoroshye. Ntibikenewe kubika umwanya winyongera mugushiraho IC, ikwiriye cyane cyane Umwanya muto hamwe na ssenariyo ntoya (nk'ibikoresho byo mu nzu byo mu nzu, ibikoresho byo gukinisha, hamwe n'amatara yo gushushanya mikoro).
Mugihe ushyiraho, ntabwo bikenewe gukosora IC yo hanze ukwayo. Gusa komeza cyangwa uyitsinde muburyo busanzwe bwumucyo, bigabanya cyane ubwubatsi. Ndetse abatangiye barashobora kubikora vuba.
2. Kugenzura neza, gushyigikira "kugenzura ibara rimwe"
Nkuko buri saro rya LED rifite ibikoresho byigenga bya IC byigenga, birashobora kugera kumucyo wigenga no guhindura amabara ya pigiseli imwe (amasaro ya LED) (nkingaruka zingirakamaro nkamazi atemba, gradient, hamwe ninyandiko yerekana), itanga uburyo bwiza bwo kwerekana neza. Irakwiriye kumashusho asaba ingaruka zumucyo utunganijwe (nko kumurika ibidukikije, kumurika inyuma kumashusho ashushanya, no kumurika ibyiciro).
3. Wiring yoroshye igabanya umubare wamakosa
Iyubakwa rya IC ryumucyo risanzwe risaba gusa insinga eshatu: "VCC (positif), GND (negative), na DAT (umurongo wibimenyetso)" kugirango ikore (moderi zimwe zirimo imirongo yisaha ya CLK), kandi ntampamvu yo guteganya andi mashanyarazi cyangwa imirongo yerekana ibimenyetso kumashusho yo hanze. Umubare winsinga ni muto, kandi umuzenguruko uroroshye.
Mugabanye "ihuriro ryihuza hagati ya IC yo hanze n’amasaro ya LED", amahirwe yamakosa aterwa ninsinga zidakabije no guhuza nabi birasanzwe bigabanuka, kandi ituze riri hejuru.
4. Igiciro kirashobora kugenzurwa kandi kirakwiriye mugihe giciriritse na gito
Nubwo igiciro cya "LED + yubatswe muri IC" kiri hejuru gato ugereranije n’amasaro asanzwe y’amatara, bivanaho amasoko atandukanye yo kugurisha no kugurisha ibicuruzwa byo hanze, bigatuma igisubizo rusange gishobora kugenzurwa cyane. Irakwiriye cyane cyane kuburebure buciriritse nuburebure hamwe na mato mato mato (nko gushushanya urugo no gushushanya ibicuruzwa bito).
Umucyo wo hanze wa IC wo hanze: IC irigenga yigenga, ihuza byoroshye nimbaraga zikomeye kandi zigoye
Ikintu nyamukuru kiranga urumuri rwo hanze rwa IC ni uko chip yo kugenzura (IC) hamwe nisaro rya LED bishyirwaho ukundi - amasaro ni amasaro asanzwe ya IC (nka 5050, 2835), mugihe IC igenzura igurishwa yigenga kumwanya runaka ku kibaho cya PCB cyumucyo (nka WS2811, TM1914, nibindi) Mubisanzwe, "IC imwe igenzura amasaro menshi ya LED" (urugero: LED imwe). Ibyiza byayo bigaragarira cyane cyane mubice bikurikira:
1-Ihuza nimbaraga nyinshi kandi ifite ubushyuhe bwiza
IC yo hanze yatandukanijwe namasaro ya LED, yirinda ikibazo cy "ubushyuhe bwo gukusanya ubushyuhe" bwa IC hamwe namasaro yoroheje mumapaki amwe. Irakwiriye cyane cyane kumirongo yumucyo mwinshi (nkabafite imbaraga zirenga 12W kuri metero hamwe nuburyo bwo kumurika cyane).
Ibishushanyo byo hanze birashobora gukwirakwiza ubushyuhe binyuze ahantu hanini h'umuringa ku kibaho cya PCB cyangwa izindi nyubako zogukwirakwiza ubushyuhe zirashobora gushirwaho kugirango bigabanye ingaruka zo kwangirika kwimikorere cyangwa kwangizwa nubushyuhe bwinshi. Iterambere ryigihe kirekire rirakwiriye cyane kubisabwa biremereye cyane (nko kumurika ubucuruzi no kumurika amatara yo hanze).
2-Igenzura ryoroshye, rishyigikira "itara ryinshi ryamatara"
Ibishushanyo byo hanze mubisanzwe bifasha "IC imwe igenzura amasaro menshi yumucyo" (nk'amatara 3 / IC, amatara 6 / IC), kandi irashobora kugera "kugenzura amabara kumatsinda" - ikwiranye na ssenariyo ifite ibisabwa bike kugirango "igenzure ibara rimwe" ariko ikenera "ingaruka zingirakamaro mu karere" (nk'amatara yo hanze yerekana amatara, amatara manini yo gukaraba urukuta).
Ibice bimwe byo hanze (nka WS2811) bishyigikira ingufu za voltage nyinshi (nka 12V / 24V). Ugereranije nibisanzwe 5V byinjijwemo muri ics, zifite imbaraga nke za voltage mugihe cyohereza intera ndende kandi zirakwiriye gukoreshwa na ultra-ndende yumucyo usaba (nkumucyo wo hanze uva kuri metero 10).
3-Amafaranga yo kubungabunga make kandi byoroshye kuyasimbuza
IC yo hanze itandukanijwe namasaro yamatara. Niba hari imikorere idahwitse ya IC, gusa IC ifite amakosa igomba gusimburwa ukwayo, bitabaye ngombwa gusimbuza umurongo wose wumucyo (niba imikorere mibi ya IC imbere, ipaki yose "itara ryamatara + IC" igomba gusimburwa). Mu buryo nk'ubwo, niba LED isaro idakora neza, nta mpamvu yo gusimbuza IC hamwe nabo. Mugihe cyo kubungabunga, igiciro cyibigize kiri hasi kandi imikorere iroroshye guhinduka.
Kubintu binini kandi birebire byo gukoresha (nk'ahantu hacururizwa no mumishinga yo hanze), inyungu yikiguzi cyo kubungabunga nyuma iragaragara.
4-Guhuza gukomeye, bikwiranye na sisitemu igoye yo kugenzura
Icyitegererezo cyo guhitamo ibishushanyo byo hanze biratandukanye. Bimwe murwego rwohejuru rwo hanze ics rushyigikira igipimo cyinshi cyo kohereza ibimenyetso hamwe numuyoboro mwinshi wo kugenzura, kandi birahujwe na sisitemu igenzura igoye (nka DMX512, Art-Net protocole), ibereye ibintu binini byubuhanga (nka sisitemu yo kumurika ibyiciro, amatara manini manini), kandi irashobora kugera kumurongo wo guhuza imirongo myinshi yumucyo.
Niba ibisabwa ari kumwanya muto, ingaruka nziza zingirakamaro, hamwe no kwishyiriraho byoroshye (nkurumuri rwibidukikije murugo, gushushanya desktop), shyira imbere guhitamo ibyubatswe mumashanyarazi ya IC.
Niba ibisabwa ari imbaraga nyinshi, intera ndende, ibintu byo hanze cyangwa kubungabunga byoroshye mugice cyanyuma (nk'inyubako yo hanze hamwe n'amatara yo gucururizamo), imirongo ya IC yo hanze igomba guhabwa umwanya wambere.
Itara rya MX rifite urumuri rutandukanye rwa LED harimo umurongo wa COB / CSP,dinamike ya pigiseli, neon flex, umurongo mwinshi wa voltage hamwe na wallwasher.Twandikireniba ukeneye ingero zo kwipimisha!
