Ni izihe nyungu za ics zubatswemo na ics zo hanze mu mirongo y'urumuri rwa LED?

Mu rwego rwaUduce tw'amatara ya LED, itandukaniro ry'ingenzi hagati ya "IC yubatswemo" na "IC yo hanze" riri mu mwanya wo gushyiraho chip yo kugenzura (IC), igena mu buryo butaziguye uburyo bwo kugenzura, imiterere y'imikorere, imiterere y'iyinjizwamo n'imiterere ifatika y'imirongo y'urumuri. Ibyiza n'itandukaniro hagati y'ibyo byombi bishobora kugereranywa neza uhereye ku bipimo byinshi, nk'ibi bikurikira:

Urumuri rwa IC rwubatswemo: IC na LED bihujwe, byoroshya imiterere n'ishyirwamo
Ikintu cy'ingenzi cy'urumuri rwa IC rwubatswemo ni ugupakira chip yo kugenzura (IC) n'urumuri rwa LED muri rusange (nk'uburyo busanzwe bwa WS2812B, SK6812, nibindi), ni ukuvuga "urumuri rumwe ruhuye na IC imwe", hatabayeho indi chip yo kugenzura yo hanze. Ibyiza byayo bigaragarira ahanini muri ibi bikurikira:

1. Imiterere mito kandi byoroshye kuyishyiraho
IC yubatswemo ihuza "LED beads + control IC" mu ipaki imwe, bigatuma imiterere rusange y'urumuri iba nto, yoroheje kandi irushaho kuba ndende. Nta mpamvu yo kubitsa umwanya w'inyongera wo gushyiraho IC, cyane cyane ahantu hato n'ahantu hato (nk'aho ibikoresho byo mu nzu bihagarara, ibikoresho byo gukina, n'amatara mato yo gushushanya).
Mu gushyiramo, nta mpamvu yo gusana IC yo hanze ukwayo. Shyira gusa cyangwa uyishyire mu buryo busanzwe bw'imirongo y'urumuri, bigabanya cyane uburyo bwo kuyikora. Ndetse n'abatangiye kuyikoresha vuba.
2. Uburyo bwo kugenzura neza, bushyigikira "igenzura ry'amabara rimwe"
Kubera ko buri saro ya LED ifite IC yigenga, ishobora kugera ku mucyo wigenga no guhindura amabara ya pikseli (amasaro ya LED) (nk'ingaruka zihindagurika nk'amazi atemba, ubugari, n'inyandiko zigaragara), bigatanga uburyo bwo kwerekana neza amashusho. Ikwiriye amashusho akeneye urumuri rwiza (nk'urumuri rwo mu kirere, urumuri rwo inyuma ku mashusho yo gushushanya, n'urumuri rwo ku rubyiniro).
3. Insinga zoroshye zigabanya umubare w'aho amakosa abera
Imirongo y'urumuri rwa IC yubatswemo ubusanzwe isaba insinga eshatu gusa: "VCC (positive), GND (negative), na DAT (signal line)" kugira ngo ikore (imwe muri moderi irimo imirongo y'isaha ya CLK), kandi nta mpamvu yo gushyiraho andi mashanyarazi cyangwa imirongo y'ibimenyetso kuri ics zo hanze. Umubare w'insinga ni muto, kandi circuit ni yo yoroshye.
Mu kugabanya "imirongo yo guhuza hagati ya IC yo hanze na LED", amahirwe yo kugira amakosa aterwa n'insinga zidakora neza no gukorana nabi aragabanuka mu buryo busanzwe, kandi umutekano ukaba mwinshi.
4. Ikiguzi kiragenzurwa kandi gikwiriye ku rugero ruciriritse n'urwo hasi
Nubwo ikiguzi cya "LED + IC imwe yubatswemo" kiri hejuru gato y'iy'amasaro asanzwe y'amatara, bikuraho ikiguzi cyo kugura no gusora cy'amasaro yo hanze, bigatuma ikiguzi rusange cy'umuti kibasha kugenzurwa. Cyane cyane ikoreshwa mu burebure buciriritse n'ubuto n'ubuciriritse n'ubuto (nk'imitako yo mu rugo n'imitako mito y'ubucuruzi).

Agace k'urumuri ka IC ko hanze: IC ni iyo hanze ubwayo, ihinduka mu buryo bworoshye kugira ngo ihuze n'ibintu bifite imbaraga nyinshi kandi bigoye
Ikintu cy'ingenzi cy'umurongo w'urumuri wa IC wo hanze ni uko chip yo kugenzura (IC) n'amasaro ya LED bishyirwa ukwabyo - amasaro ni amasaro asanzwe ya IC (nk'amasaro 5050, 2835), mu gihe IC yo kugenzura ishyizwe ahantu hihariye ku kibaho cya PCB cy'umurongo w'urumuri (nk'urugero WS2811, TM1914, nibindi). Ubusanzwe, "IC imwe igenzura amasaro menshi ya LED" (urugero, IC imwe igenzura amasaro atatu ya LED). Ibyiza byayo bigaragarira ahanini muri ibi bikurikira:

1-Irahuye n'imbaraga nyinshi kandi igabanya ubushyuhe neza
IC yo hanze itandukanijwe n'amatara ya LED, birinda ikibazo cyo "kwiyongera k'ubushyuhe" bwa IC n'amatara ari mu ipaki imwe. Ikwiriye cyane cyane amatara afite ingufu nyinshi (nk'ayo afite imbaraga zirenga 12W kuri metero imwe n'amatara afite urumuri rwinshi).
Inkingi zo hanze zishobora gukwirakwiza ubushyuhe mu gice kinini cy'icyuma gikozwe mu muringa kiri ku kibaho cya PCB cyangwa izindi nyubako zigabanya ubushyuhe zishobora gukorwa kugira ngo zigabanye ibyago byo kwangirika k'imikorere cyangwa kwangirika guterwa n'ubushyuhe bwinshi. Kuba zihamye igihe kirekire birakwiriye cyane gukoreshwa mu bikoresho byinshi (nk'amatara yo mu bucuruzi n'udusanduku tw'amatara yo hanze).

2-Gucunga neza, bishyigikira "gushyira hamwe amasaro y'amatara menshi"
Ubusanzwe, ic zo hanze zishyigikira "IC imwe igenzura amasaro menshi y'urumuri" (nk'amatara 3/IC, amatara 6/IC), kandi zishobora kugera ku "kugenzura amabara mu itsinda" - bikwiranye n'ibintu bike bikenewe kugira ngo "bigenzurwe n'amabara y'ahantu hamwe" ariko bikeneye "ingaruka zihindagurika mu karere" (nk'amatara yo hanze y'inyubako, amatara manini yoza inkuta).
Ic zimwe na zimwe zo hanze (nka WS2811) zishyigikira ingufu z'amashanyarazi (nka 12V/24V). Ugereranyije n'ic zisanzwe za 5V zikoreshwa muri ic zubatswemo, zifite ingufu nke zo kugabanya ingufu z'amashanyarazi mu gihe cyo kohereza intera ndende kandi zikwiriye gukoreshwa mu miyoboro y'urumuri miremire cyane (nka ibyuma by'urumuri byo hanze birenga metero 10).

3-Ikiguzi cyo kubungabunga kiri hasi kandi byoroshye gusimbuza
IC yo hanze itandukanyijwe n'amasaro y'itara. Iyo hari IC ikoze nabi, IC ifite ikibazo ni yo yonyine igomba gusimburwa ukwayo, hatabayeho gusimbuza umurongo wose w'urumuri (niba IC y'imbere idakora neza, ipaki yose ya "amasaro y'itara + IC" igomba gusimburwa). Mu buryo nk'ubwo, iyo amasaro ya LED adakora neza, nta mpamvu yo gusimbuza IC hamwe nayo. Mu gihe cyo kuyasana, igiciro cy'ibice biba biri hasi kandi imikorere iba yoroshye.
Ku bijyanye n'ikoreshwa rinini n'iry'igihe kirekire (nk'amaduka manini n'imishinga yo hanze), inyungu ikomoka ku ikoreshwa ry'iyi serivisi nyuma iragaragara cyane.

4-Ikorana neza cyane, rikwiriye sisitemu zikomeye zo kugenzura
Uburyo bwo guhitamo imashini zo hanze buratandukanye cyane. Zimwe muri imashini zo hanze zigezweho zishyigikira uburyo bwo kohereza ibimenyetso ku rwego rwo hejuru n'imiyoboro myinshi yo kugenzura, kandi zijyanye na sisitemu zihambaye zo kugenzura (nka DMX512, Art-Net protocol), zikwiriye imiterere minini y'ubuhanga (nk'amatara yo ku rubyiniro, amatara manini yo gukiniraho), kandi zishobora kugenzura imiyoboro myinshi y'urumuri mu buryo butaziguye.

Niba ibisabwa ari ahantu hato, ingaruka nziza z'ikirere, no gushyiraho ibintu byoroshye (nk'amatara yo mu rugo, imitako yo ku meza), shyira imbere guhitamo utubari tw'urumuri rwa IC twubatswemo.
Niba ibisabwa ari iby’ingufu nyinshi, intera ndende, ibikorwa byo hanze cyangwa ibikorwa byoroshye byo kubungabunga mu gihe cya nyuma (nk’inyubako zo hanze n’amatara yo mu maduka), amatara yo hanze ya IC agomba guhabwa umwanya wa mbere.
Amatara ya MX afite amatara atandukanye ya LED arimo COB/CSP strip,agace ka pixel gahinduka, flex ya neon, umurongo w'amashanyarazi menshi n'icyuma gikonjesha inkuta.Twandikireniba ukeneye ingero zo gupimisha!
