Cov txiaj ntsig ntawm cov built-in ics thiab cov ics sab nraud hauv cov teeb LED yog dab tsi?

Nyob rau hauv thaj teb ntawmCov teeb LED, qhov sib txawv tseem ceeb ntawm "built-in IC" thiab "external IC" nyob rau hauv qhov chaw teeb tsa ntawm lub chip tswj (IC), uas txiav txim siab ncaj qha rau hom kev tswj, cov yam ntxwv ua haujlwm, qhov nyuaj ntawm kev teeb tsa thiab cov xwm txheej siv tau ntawm cov teeb ci. Qhov zoo thiab qhov sib txawv ntawm ob qho no tuaj yeem sib piv tau meej meej los ntawm ntau qhov ntev, raws li hauv qab no:

Ua-hauv IC teeb strip: IC thiab LED kev sib xyaw ua ke, ua kom yooj yim tsim thiab teeb tsa
Lub ntsiab lus tseem ceeb ntawm lub teeb ci IC uas ua rau hauv lub teeb ci yog kom ntim cov khoom siv tswj (IC) thiab lub teeb LED tag nrho (xws li cov qauv WS2812B, SK6812, thiab lwm yam), uas yog, "ib lub teeb ci sib raug rau ib lub IC", tsis tas yuav muaj lwm lub teeb tswj sab nraud ntxiv. Nws cov txiaj ntsig feem ntau pom hauv cov hauv qab no:

1. Cov qauv me me thiab kev teeb tsa yooj yim
Lub IC uas ua ke nrog "LED hlaws dai + tswj IC" ua ke hauv ib pob, ua rau tag nrho cov qauv ntawm lub teeb ci nyias dua, sib dua thiab nyias dua. Tsis tas yuav tsum khaws qhov chaw ntxiv rau kev teeb tsa IC, uas yog qhov tshwj xeeb tshaj yog rau qhov chaw nqaim thiab cov xwm txheej me me (xws li cov rooj tog teeb pom kev zoo, cov khoom siv ua si, thiab cov teeb pom kev zoo me me).
Thaum txhim kho, tsis tas yuav kho lub IC sab nraud cais. Tsuas yog lo lossis xaim nws hauv txoj kev ib txwm muaj ntawm cov teeb ci, uas txo qhov nyuaj ntawm kev tsim kho. Txawm tias cov neeg pib tshiab tuaj yeem ua haujlwm nws sai.
2. Kev tswj hwm zoo, txhawb nqa "kev tswj xim ib qho"
Vim tias txhua lub LED hlaws dai muaj ib lub IC ywj pheej, nws tuaj yeem ua tiav qhov kaj thiab kev hloov xim ntawm cov pixels (LED hlaws dai) (xws li cov teebmeem dynamic xws li dej ntws, gradient, thiab cov ntawv nyeem), muab kev pom kev zoo dua. Nws yog qhov tsim nyog rau cov xwm txheej uas xav tau cov teebmeem teeb pom kev zoo (xws li teeb pom kev zoo ib puag ncig, backlighting rau cov duab pleev xim, thiab teeb pom kev zoo ntawm theem).
3. Kev txuas hluav taws xob yooj yim txo cov teeb meem uas muaj teeb meem
Cov teeb ci IC uas ua rau hauv feem ntau tsuas yog xav tau peb txoj hlua xwb: "VCC (zoo), GND (tsis zoo), thiab DAT (kab teeb liab)" kom ua haujlwm (qee cov qauv suav nrog cov kab moos CLK), thiab tsis tas yuav npaj cov khoom siv hluav taws xob ntxiv lossis cov kab teeb liab rau cov ics sab nraud. Cov xov hlau me me, thiab lub voj voog yooj yim dua.
Los ntawm kev txo cov "kev sib txuas ntawm IC sab nraud thiab cov hlaws LED", qhov tshwm sim ntawm qhov ua yuam kev los ntawm cov xov hlau xoob thiab kev sib cuag tsis zoo yog qhov txo qis, thiab qhov ruaj khov siab dua.
4. Tus nqi tswj tau thiab nws tsim nyog rau cov xwm txheej nruab nrab thiab me me
Txawm hais tias tus nqi ntawm ib qho "LED + built-in IC" siab dua me ntsis ntawm cov teeb pom kev zoo ib txwm muaj, nws tshem tawm cov nqi yuav khoom sib cais thiab cov nqi soldering ntawm cov ics sab nraud, ua rau tag nrho cov nqi daws teeb meem yooj yim dua. Nws yog qhov tshwj xeeb tshaj yog rau qhov ntev nruab nrab thiab me me thiab cov ntawv thov me me (xws li kho kom zoo nkauj hauv tsev thiab kho kom zoo nkauj me me).

Sab nraud IC lub teeb strip: Lub IC yog ywj pheej sab nraud, hloov kho tau yooj yim rau cov xwm txheej muaj zog thiab nyuaj
Lub ntsiab lus tseem ceeb ntawm lub teeb ci IC sab nraud yog tias cov khoom siv tswj (IC) thiab cov hlaws LED tau teeb tsa sib cais - cov hlaws yog cov hlaws IC ib txwm muaj (xws li 5050, 2835 hlaws), thaum lub teeb ci IC tau txuas rau ib qho chaw tshwj xeeb ntawm PCB lub rooj tsavxwm ntawm lub teeb ci (xws li WS2811, TM1914, thiab lwm yam). Feem ntau, "ib qho IC tswj ntau lub hlaws LED" (piv txwv li, ib qho IC tswj peb lub hlaws LED). Nws cov txiaj ntsig feem ntau pom tseeb hauv cov hauv qab no:

1-Nws sib xws nrog lub zog siab thiab muaj cua sov zoo dua
Lub IC sab nraud raug cais tawm ntawm cov teeb LED, zam qhov teeb meem "kub sib sau ua ke" ntawm IC thiab cov teeb hauv tib pob. Nws yog qhov tshwj xeeb tshaj yog rau cov teeb ci siab (xws li cov uas muaj zog tshaj 12W ib 'meter' thiab cov teeb pom kev zoo siab).
Cov ics sab nraud tuaj yeem tso cua sov tawm ntawm thaj chaw loj dua ntawm cov ntawv ci tooj liab ntawm PCB board lossis cov qauv tso cua sov ntxiv tuaj yeem tsim los txo qhov kev pheej hmoo ntawm kev ua haujlwm poob qis lossis kev puas tsuaj los ntawm qhov kub siab. Lawv qhov ruaj khov mus sij hawm ntev yog qhov tsim nyog dua rau cov ntawv thov siab (xws li teeb pom kev lag luam thiab cov thawv teeb tshaj tawm sab nraum zoov).

2-Kev tswj hwm yooj ywm, txhawb nqa "kev sib sau ua ke ntawm ntau lub teeb ci"
Feem ntau cov ICs sab nraud txhawb nqa "ib qho IC tswj ntau lub teeb ci" (xws li 3 lub teeb/IC, 6 lub teeb/IC), thiab tuaj yeem ua tiav "kev tswj xim los ntawm pawg" - tsim nyog rau cov xwm txheej uas muaj qhov xav tau tsawg rau "kev tswj xim ib qho" tab sis xav tau "cov teebmeem dynamic hauv cheeb tsam" (xws li teeb pom kev zoo sab nraum zoov, teeb ntxuav phab ntsa loj).
Qee cov ics sab nraud (xws li WS2811) txhawb nqa cov inputs voltage siab dua (xws li 12V / 24V). Piv nrog rau cov input 5V ntawm cov ics built-in, lawv muaj tsawg dua qhov voltage attenuation thaum lub sijhawm xa mus deb thiab tsim nyog rau cov ntawv thov teeb ci ultra-ntev (xws li cov teeb ci sab nraum zoov tshaj 10 meters).

3-Tus nqi kho tsawg thiab yooj yim hloov
Lub IC sab nraud raug cais tawm ntawm cov hlaws teeb. Yog tias muaj qee lub IC ua haujlwm tsis zoo, tsuas yog lub IC uas ua haujlwm tsis zoo yuav tsum tau hloov cais xwb, tsis tas yuav hloov tag nrho cov teeb ci (yog tias lub IC sab hauv ua haujlwm tsis zoo, tag nrho cov "hluav taws teeb + IC" yuav tsum tau hloov). Ib yam li ntawd, yog tias cov hlaws LED ua haujlwm tsis zoo, tsis tas yuav hloov lub IC nrog rau lawv. Thaum lub sijhawm txij nkawm, tus nqi ntawm cov khoom qis dua thiab kev ua haujlwm yooj ywm dua.
Rau cov xwm txheej loj thiab siv mus sij hawm ntev (xws li cov khw loj thiab cov haujlwm sab nraum zoov), qhov zoo dua ntawm kev saib xyuas tom qab yog qhov pom tseeb dua.

4-Kev sib raug zoo, tsim nyog rau cov txheej txheem tswj hwm nyuaj
Cov qauv xaiv ntawm cov ics sab nraud muaj ntau yam sib txawv. Qee cov ics sab nraud siab txhawb nqa cov nqi xa tawm siab dua thiab ntau txoj kev tswj hwm, thiab sib xws nrog cov kab ke tswj hwm nyuaj (xws li DMX512, Art-Net protocol), tsim nyog rau cov xwm txheej engineering loj (xws li cov kab ke teeb pom kev zoo, teeb pom kev zoo hauv chaw loj), thiab tuaj yeem ua tiav kev tswj hwm sib txuas ntawm ntau lub teeb ci.

Yog tias qhov yuav tsum tau ua yog rau qhov chaw me me, cov teebmeem zoo nkauj, thiab kev teeb tsa yooj yim (xws li lub teeb pom kev zoo hauv tsev, kho kom zoo nkauj ntawm lub desktop), muab qhov tseem ceeb rau kev xaiv cov teeb ci IC uas ua rau hauv.
Yog tias qhov yuav tsum tau ua yog rau lub zog siab, kev deb ntev, cov xwm txheej sab nraum zoov lossis kev saib xyuas yooj yim hauv theem tom qab (xws li lub tsev sab nraum zoov thiab lub teeb pom kev zoo hauv khw loj), cov teeb IC sab nraud yuav tsum tau muab qhov tseem ceeb.
MX teeb pom kev zoo muaj ntau yam teeb LED strips suav nrog COB / CSP strip,dynamic pixel strips, neon flex, high voltage strip thiab wallwasher.Tiv tauj pebyog tias koj xav tau cov qauv rau kev xeem!
