Flickering yog ib qho teeb meem feem ntau nrog LED strips. Los ntawm kev nyeem cov kab lus no, koj yuav kawm txog hom flickering, qhov ua rau flickering, thiab yuav ua li cas kho flickering.
Cia peb pib.
Dab tsi yog qhov txawv ntawm Flickering?
Flicker yog lub voj voog ceev rau / tawm ntawm lub teeb ci. Nws tuaj yeem yog txhob txwm ua (nrog tsev so lossis kev hais kwv txhiaj flashing), tab sis feem ntau, nws tsuas yog kev ntxhov siab xwb.
Muaj ob hom flicker: pom thiab pom tsis pom. Pom pom flicker yog txhua yam uas muaj zaus hauv qab 100 Hz (piv txwv li, 100 zaug ib ob lossis tsawg dua). Invisible flicker tshwm sim saum 100 Hz thiab tsis pom ntawm peb lub qhov muag thaum nws nyob. Ob hom flicker yog qhov tsis noj qab haus huv - cov kab mob feem ntau muaj xws li kiv taub hau, mob qhov muag, mob taub hau, migraines, thiab kev paub tsis meej. Pom pom flicker tuaj yeem ua rau qaug dab peg hauv cov neeg uas muaj mob vwm.
Dab tsi yog Qhov Ua Rau LED Sawb Lub Teeb Flickering?
Nov yog qee qhov ua rau LED strip flickers.
Pom pom Flicker ua rau
Kev sib txuas tsis zoo
Flicker pib (los yog poob qis heev) tom qab kev sib txuas. Qhov laj thawj tseem ceeb yog tias kev sib txuas tsis zoo, tsis sib xws, lossis tsis sib xws tuaj yeem ua rau flicker los ntawm kev sib txuas ua ke thiab rhuav tshem. Nws tshwm sim feem ntau nyob rau hauv solderless connectors thiab yog tsis zoo li tshwm sim nyob rau hauv soldering.
LED sawb flicker yuav hloov los yog ploj thaum koj nias lub solder-free connector.
Qhov tsis sib xws
Qhov no feem ntau tshwm sim thaum LED strip yog dimmable. Ua ntej, koj yuav tsum xyuas kom meej tias koj LED sawb thiab tsav tsheb tau txais kev txhawb nqa rau dimming. Tom qab ntawd, koj yuav tsum xyuas kom meej tias cov dimmer thiab cov txheej txheem tsav tsheb sib xws. Piv txwv li, koj tsis tuaj yeem siv 0-10V dimmer nrog tus tsav tsheb DALI dimming.
Kev siv hluav taws xob ntau dhau los yog tsis muaj zog
LED tsav overload yog ib qho ntawm feem ntau ua rau LED sawb flicker.
LED tsav tsheb feem ntau muaj kev tiv thaiv overload. Thaum overloaded, tus tsav tsheb LED yuav nyob tas li thiab tawm. Tom qab ntawd cov sawb LED tseem yuav nyob tas li ntawm thiab tawm, yog li nws zoo li flickering.
Tus tsav tsheb tsis zoo LED tuaj yeem, qee lub sijhawm, kuj ua rau LED sawb flicker.
Teeb meem LED Sawb
LED sawb qee zaum flickers vim tias LED sawb tsis zoo.
Feem ntau, nws yog qhov tsis zoo ntawm kev sib txuas ntawm LED nti thiab tus tuav.
Hauv daim duab hauv qab no dua, koj tuaj yeem pom cov qauv sab hauv ntawm SMD LED hlaws. Qhov uas emits lub teeb yog LED nti, thiab LED nti yog txuas nrog lub LED tuav los ntawm ib tug kub hlau. Thaum LED nti thiab lub bracket tsis txuas zoo, qhov tam sim no tuaj yeem dhau los thiab qee zaum tsis tau, thiab LED yuav flicker.
Piv rau SMD LEDs, CSP thiab COB LEDs tsis muaj cov xov hlau kub thiab tuaj yeem zam qhov teeb meem no. Yog xav paub ntxiv, thov nyeem cov CSP LED Sawb VS COB LED Sawb.
Kuj tseem muaj qhov xwm txheej uas cov hlaws LED thiab PCBs tsis zoo soldered. Thaum koj pom ib feem ntawm LED sawb blinking, koj nias qhov no ntawm LED nrog koj txhais tes. Lub flicker yuav hloov lossis ploj mus.
Invisible Flicker ua rau
Tej zaum koj pom qee cov kab ntsug hauv koj lub xov tooj smartphone lub koob yees duab duab thiab saib qee qhov strobe hauv cov khoom txav, qhov tshwm sim tshwm sim los ntawm qhov tsis pom strobe.
AC zog LED Sawb
Lub teeb hluav taws xob flicker vim tias feem ntau ntawm lub ntiaj teb hluav taws xob kis tau los ntawm kev hloov tam sim no (AC). Raws li nws lub npe implies, AC hloov nws cov kev taw qhia ーー ntws nyob rau hauv ib qho kev taw qhia thiab ces tig ntawm tus nqi ntawm 50 mus rau 60 zaug ib ob. Qhov no feem ntau yuav siv daim ntawv ntawm sine yoj. Txawm li cas los xij, tam sim no ncaj qha (DC) yog qhov tsis tu ncua thiab ib txwm ntws hauv ib qho kev taw qhia.
Thaum qhov tam sim no ntws mus rau qhov sib txawv, txhua yam uas txuas rau hauv kab poob lub zog tam sim ntawd. Vim tias qhov tam sim no txuas ntxiv mus rau qhov sib txawv, txhua lub teeb yuav flicker.
Qhov no kuj yog vim li cas vim li cas AC zog LED sawb flickering.
PWM Dimming
PWM teeb liab dimming ua rau pom tsis pom flickers.
PWM yog lub hom phiaj kev tswj hwm ntawm DC lub zog ntawm lub xeev rau thiab tawm. Los ntawm qhov sib txawv ntawm lub sijhawm sib txawv ntawm nws qhov chaw nyob thiab tawm, PWM tuaj yeem siv los tsim kev nkag siab ntawm qhov sib txawv brightness. Txawm li cas los xij, LED yog 0% lossis 100% ci. Txhawm rau ua tiav qhov kev xav ntawm 50% ci ntsa iab, LED yog ib nrab ntawm lub sijhawm ntawm 0% ci ntsa iab (tawm) thiab ib nrab lub sijhawm ntawm 100% ci ntsa iab (on).
Qhov flicker no feem ntau tsis tsim teeb meem vim nws tsis pom. Txawm li cas los xij, rau kev kaw cov yeeb yaj kiab, cov flickers tsis pom no yuav yog kev puas tsuaj.
Lub teeb flickering hauv ib daim vis dis aus dhau los ua pov thawj thiab pom tseeb vim tias lub koob yees duab lub thav duab ib ob (FPS) cov ntaubntawv povthawj siv tsis ua raws li qhov zaus ntawm hluav taws xob. Qhov no yog hu ua 'strobe effect'.
Yuav luag tag nrho cov LED sawb dimmers thiab "xim hloov" controllers (CCT lossis RGB) ntsia rau ntawm qhov tsis tshua muaj hluav taws xob DC sab ntawm lub voj voog siv PWM kom ua tiav lawv qhov kev xav tau. Hmoov tsis zoo, ntau PWM dimmers siv zaus uas tsawg dhau. Qhov zaus yuav tsum yog 25,000 Hz lossis siab dua kom tshem tawm qhov cuam tshuam ntawm PWM flicker. Tseem, feem ntau PWM dimmers tsis suav nrog PWM zaus specification, uas feem ntau qhia tias lawv siv ntau zaus ntawm ob peb puas Hz feem ntau.
