Yuav tsum ua li cas thaum lub teeb ci ntsa iab thaum lub sijhawm tsaus ntuj?

Cov teeb LED, nrog lawv lub teeb mos mos, ntau yam kev teeb tsa thiab cov haujlwm dimming yooj ywm, tau dhau los ua cov khoom siv teeb pom kev zoo rau kev kho kom zoo nkauj hauv tsev, teeb pom kev lag luam thiab kho kom zoo nkauj toj roob hauv pes. Txawm li cas los xij, ntau tus neeg siv ntsib teeb meem ntawm flickering thaum siv lub luag haujlwm dimming. Ntau tus neeg siv ntseeg tias "me ntsis flickering tsis cuam tshuam rau kev siv", tab sis lawv tsis xav txog cov kev pheej hmoo uas yuav tshwm sim: Ua ntej, nws cuam tshuam rau kev pom kev, tshwj xeeb tshaj yog nyob rau hauv qhov chaw xws li chav pw, chav kawm, thiab cov khoom lag luam uas xav tau lub teeb ruaj khov heev. Flickering tuaj yeem ua rau pom kev qaug zog, mob taub hau, thiab txawm tias ua kom cov menyuam yaus myopia sai dua thaum raug rau qhov flickering qis zaus ntev. Kuj tseem muaj ntau yam teeb meem ntxiv.
1 Feem Ntau: Qhov Tsis Sib Haum ntawm Dimmer thiab Light Strip (60% ntawm Cov Neeg Mob)
Qhov no yog qhov ua rau kuv pom #1—tsis txhob txhawj. Cov LED strips tsis zoo li cov teeb incandescent qub; koj tsis tuaj yeem txo qhov voltage kom dim lawv. Lawv xav tau kev tswj tam sim no thiab kev xa cov teeb liab kom meej. Yog tias koj lub dimmer thiab strip tsis "hais tib yam lus," flicker yog qhov tseeb. Cia peb ua qhov no yooj yim—ntawm no yog yam yuav tsum xyuas:
- Hom Dimmer Tsis Yog: Tsis haum rau dimmers rau LED teeb strips. Tsis tas li ntawd, cov strips sib txawv (xws li RGBW lossis cov addressable) siv cov "codes" dimming sib txawv - kev sib xyaw dimmers los ntawm ntau hom yuav ua rau txhua yam puas tsuaj. Piv txwv li, ib5V WS2812B daim kab xevxav tau lub teeb liab tshwj xeeb 800kHz, thaum lub12V DMX sawbxav tau nws tus kheej - lawv yuav tsis ua haujlwm ua ke.
- PWM Zaus Tsis Sib Xws: Feem ntau cov tswj LED zoo muaj PWM zaus ntawm 200-1000Hz—koj lub qhov muag tsis pom qhov flicker saum 200Hz. Tab sis dimmers thiab strips pheej yig? Lawv zaus feem ntau tsuas yog 120-180Hz. Thaum koj txo qhov ci ntsa iab, qhov flicker ntawd yuav pom—thiab nws ua rau neeg chim siab. Tsuas yog hloov kho mus rau dimmer zoo dua kho qhov no.
- Kev Thauj Khoom Tsis Sib Xws: Txhua lub dimmer muaj "qhov chaw zoo" rau qhov nws tuaj yeem tswj tau lub zog ntau npaum li cas. Yog tias koj cov strips siv lub zog tsawg dua li qhov tsawg kawg nkaus ntawm dimmer (feem ntau nrog cov thyristor dimmers qub) lossis ntau dua li nws qhov siab tshaj plaws, koj yuav tau txais flicker. Nws zoo li sim khiav lub teeb me me ntawm lub dimmer ua rau lub chandelier loj - tsis ua haujlwm zoo.

2 Yooj Yim Rau Kev Nco: Kev Muab Fais Fab Tsis Zoo
Xav txog lub hwj chim ua "lub plawv" ntawm koj lub LED strip - yog tias nws tsis muaj zog lossis tsis zoo, txhua yam yuav tsis zoo. Kuv tau pom ntau tus neeg siv khoom tsis quav ntsej qhov no, tab sis nws yog ib qho kev kho yooj yim thaum koj paub tias yuav tsum nrhiav dab tsi. Nov yog cov teeb meem hwj chim feem ntau uas kuv ntsib:
- Cov Khoom Siv Fais Fab Tsis Zoo: Cov khoom siv fais fab pheej yig tsis zoo - lawv tsis muaj cov capacitors txaus los lim cov hluav taws xob kom zoo. Qhov ntawd txhais tau tias lub zog DC uas lawv tso tawm muaj ntau "ripple" (cov hluav taws xob AC me me sib xyaw ua ke). Thaum koj ua kom lub strip tsaus, cov hluav taws xob hloov pauv sai, ua rau lub zog poob - thiab flicker. Kuv tau sim cov khoom siv fais fab 12V pheej yig uas qhov ripple no yog 10% ntawm lub zog ntsuas - qhov ntawd ntau dhau lawm, thiab nws yooj yim kho los ntawm kev hloov kho mus rau lub zog zoo.
- Qhov hluav taws xob lossis lub zog tsis txaus: Qhov hluav taws xob tso zis ntawm lub zog yuav tsum zoo ib yam li ntawm lub teeb ci, thiab lub zog yuav tsum siab dua 30% ntawm tag nrho lub zog ntawm lub teeb ci. Tsuas yog txoj kev no thiaj li muaj lub zog txaus los tsav lub teeb ci.
- Lub zog fais fab laus lossis kub dhau: Yog tias lub zog fais fab siv ntev dhau, cov khoom sab hauv yuav laus, thiab cov zis tam sim no yuav tsis ruaj khov, uas yuav ua raulub teeb stripskom flicker intermittently.

3 Qhov Yooj Yim Kho: Cov Xov Hlau Tsis Zoo lossis Kev Sib Txuas Xoob
Thaum koj ua DIY lub teeb strips, feem ntau yog vim tsis raug xov hlau lossis kev sib txuas, lub teeb strips yuav flicker.
- Cov xov hlau tsis zoo: Cov kev sib txuas ntawm cov teeb pom kev zoo thiab lub zog fais fab, nrog rau lub dimmer, tsis tau ua kom zoo, ua rau muaj kev xa hluav taws xob tsis tu ncua thiab ntsais muag.
- Rov qab cov qhov zoo thiab qhov tsis zoo: Qhov no yuav ua rau muaj kev ntsais muag thaum lub sijhawm tsaus ntuj, qhov kaj tsis zoo, thiab txawm tias tsis ua rau tsaus ntuj li qub
- Yuam kev ntawm txoj kev txuas: Thaum ntau lub teeb ci txuas ua ke, kev sib txuas ua ke tsis tau siv, ua rau muaj kev faib hluav taws xob tsis sib npaug.
- Kev sib cuag qhov chaw oxidation: Tom qab siv ntev, qhov interface ntawm lub teeb strip oxidizes thiab tig dub, ua rau tsis ruaj khov tam sim no kis tau thiab flickering ntawm lub teeb strip.

4 Lwm Yam Ua Rau: Daim Ntawv Qhia Nws Tus Kheej lossis Kev Cuam Tshuam Ib puag ncig
- Cov Teeb Ci Tsis Zoo: Cov teeb pheej yig siv cov hlaws LED tsis zoo thiab cov khoom siv tsis zoo. Cov hlaws tuaj yeem hnav lossis poob, lossis cov teeb tsis tso cua sov zoo. Thaum koj txo qhov kub, qhov kub nce siab, thiab cov teeb yuav kaw ib ntus - ua rau muaj teeb ci ntsa iab. Qee cov teeb pheej yig txawm tias muaj qhov tsis zoo uas ua rau lawv tsis tuaj yeem txo qhov kub yam tsis muaj teeb ci ntsa iab. Yog tias qhov no yog qhov teeb meem, hloov cov teeb mus rau ib qhotsis muaj flicker strip.
-Kev cuam tshuam hluav taws xob: Thaum lub tshuab cua txias, lub tub yees, lossis lub qhov cub microwave qhib lossis kaw, nws yuav tsim kev cuam tshuam hluav taws xob, uas yuav cuam tshuam rau lub teeb liab PWM thiab ua rau lub teeb ci ntsa iab.
- Kev tso cua sov tsis zoo: Cov teeb ci tau teeb tsa rau hauv qhov chaw nqaim uas tsis muaj kev ntsuas cua sov kom zoo. Thaum lub sijhawm tsaus ntuj, kev hloov pauv ntawm lub zog ua rau qhov kub thiab txias nce ntxiv, ua rau kev ua haujlwm tsis zoo ntawm cov hlaws teeb thiab lub chip tsav tsheb. Yog li ntawd, cov teeb ci yuav ntsais muag.

Hais txog qhov xwm txheej uas qhov screen flickering, ntawm no yog qee qhov kev daws teeb meem los daws nws.

Kauj Ruam 1: Tshawb xyuas cov xov hlau
Nov yog thawj kauj ruam uas kuv ua nrog txhua tus neeg siv khoom—nws yooj yim, tsis tas yuav them nqi dab tsi, thiab kho feem ntau cov teeb meem yooj yim ntawm lub teeb ci ntsa iab. Nov yog yam yuav tsum ua:
1. Tua Hluav Taws Xob: Tshem lub ntsaws hluav taws xob kom tsis txhob muaj kev pheej hmoo ntawm hluav taws xob poob siab.
2. Xyuas cov ncej zoo thiab cov ncej tsis zoo: Xyuas kom tseeb tias cov ncej zoo thiab cov ncej tsis zoo ntawm cov teeb ci, cov dimmers, thiab cov khoom siv fais fab tau txuas nrog kom raug. Yog tias lawv txuas tsis raug, kho qhov kev taw qhia ntawm cov xov hlau thiab rov sim dua.
3. Kev sib txuas kom nruj: Xyuas seb txhua qhov kev sib txuas puas ruaj khov; yog tias muaj kev oxidation ntawm cov chaw sib txuas, so lawv kom huv nrog cawv.
4. Tshawb xyuas txoj kev txuas hluav taws xob: Thaum muaj ntau lub teeb ci sib txuas ua ke, siv cov hluav taws xob sib txuas ua ke kom tsis txhob muaj kev sib txuas ua ke.
Tom qab tshuaj xyuas tas, sim qhib lub hwj chim ntawm qhov chaw. Yog tias lub teeb tsis ci ntsa iab lawm, nws qhia tias qhov teeb meem yog nyob rau hauv cov xov hlau; yog tias nws tseem ci ntsa iab, yuav tsum tau daws teeb meem ntxiv.

Kauj Ruam 2: Tshawb xyuas qhov Chaw Muab Fais Fab
1. Tshawb xyuas cov yam ntxwv ntawm lub zog: Xyuas kom tseeb tias qhov hluav taws xob tso zis thiab lub zog ntawm lub zog muab hluav taws xob phim cov kev xav tau ntawm lub teeb ci. Lub zog ntawm lub zog muab hluav taws xob yuav tsum ntau dua 1.2 npaug ntawm tag nrho lub zog ntawm lub teeb ci kom tsis txhob muaj kev thauj khoom tsis txaus.
2. Kev sim hloov lub hwj chim: Yog tias muaj kev xav tias muaj teeb meem zoo ntawm lub hwj chim, hloov nws nrog lub hwj chim ntawm tib yam kev qhia thiab ua qhov kev sim ua kom lub hwj chim ci ntsa iab.
3. Tshawb xyuas seb qhov hluav taws xob puas hloov pauv: Saib seb qhov flickering puas tshwm sim tib lub sijhawm thaum cov khoom siv hluav taws xob muaj zog pib thiab nres. Yog tias nws tshwm sim, lub zog tswj hluav taws xob tuaj yeem ntsia tau rau ntawm qhov kawg ntawm lub zog nkag.

Kauj Ruam 3: Xyuas seb cov khoom siv dimming puas yog qhov kev xaiv zoo
Yog tias cov xov hlau thiab lub hwj chim muab tau zoo, ces qhov teeb meem yuav yog tias lub cuab yeej dimming tsis sib xws nrog lubLED stripKoj tuaj yeem sim cov kev daws teeb meem hauv qab no: Paub meej tias hom teeb ci ntawm LED strip: Xyuas seb lub LED strip puas yog monochrome, RGB, lossis RGBW.

Cov no tsuas yog cov kev daws teeb meem yooj yim xwb. Yog tias koj ntsib teeb meem nyuaj dua ntsig txog LED teeb strips, thov koj xav tiv tauj peb.tiv tauj peb.
