Kov dimming LED rooj teeb
Txoj cai ntawm LED dimmer
LED dimmer yog ib qho tseem ceeb ntawm cov teeb niaj hnub no, nws yog los ntawm kev kho qhov loj ntawm lub zog hluav taws xob, los kho qhov ci ntawm LED teeb. Nrog rau kev txhim kho txuas ntxiv thiab kev txhim kho ntawm LED teeb pom kev lag luam, LED teeb tau dhau los ua cov khoom lag luam tseem ceeb hauv kev teeb pom kev hauv tsev thiab sab nraum zoov, yog li kev siv LED dimmers tau muab tso rau hauv kev xav tau ntau dua. Kab lus no yuav qhia txog lub hauv paus ntsiab lus ntawm LED dimmer thiab nws ua haujlwm li cas nrog LED teeb kom nkag siab zoo dua thiab siv cov cuab yeej no.
Lub hauv paus ntsiab lus ntawm LED dimmer
Lub hauv paus ntsiab lus ntawm LED dimmer yog hloov qhov ci ntsa iab ntawm qhov tso zis los ntawm kev kho qhov DC fais fab mov voltage ntawm lub teeb. Txij li thaum lub teeb ci LED yog lub teeb hluav taws xob ncaj qha tam sim no, nws yog qhov tsim nyog los hloov qhov hluav taws xob ntawm nws cov khoom siv hluav taws xob ncaj qha thaum siv los tswj qhov ci ntawm lub teeb ci LED.
Circuit Court ntawmLED teebsuav nrog peb lub hauv paus tseem ceeb, xws li cov khoom siv hluav taws xob, qhov chaw tam sim no thiab LED teeb qhov chaw nws tus kheej. Cov khoom siv hluav taws xob muab cov hluav taws xob sib thooj los tsav lub teeb ci LED, thaum qhov chaw tam sim no ua kom muaj kev ruaj ntseg ntawm LED teeb qhov chaw los ntawm kev ua kom cov tam sim no ntws los ntawm LED tsis hloov. Yog li ntawd, lub luag haujlwm tseem ceeb ntawm lub dimmer yog los kho qhov hluav taws xob qhov hluav taws xob, uas cuam tshuam qhov ci ntsa iab ntawm LED teeb qhov chaw. Dimmer feem ntau los ntawm peb txoj hauv kev kom ua tiav LED lub zog hluav taws xob tswj hluav taws xob: PWM kev hloov pauv, kev hloov pauv hluav taws xob thiab qhov hloov pauv tam sim no.
1. PWM modulation
PWM modulation yog ib qho ntawm feem ntau siv LED dimmer txoj kev cai. Hom kev hloov pauv no hloov pauv lub zog hluav taws xob ntawm qee zaus thiab tswj kev ua haujlwm ntawm lub zog hluav taws xob hauv txhua lub voj voog, yog li cuam tshuam rau qhov ci ntawm LED teeb. Dynamic dimming tuaj yeem ua tiav los ntawm PWM kev hloov kho, nrog rau kom ua tau raws li qhov xav tau teeb pom kev sib txawv.
2. Kev sib koom tes ua haujlwm ntawmLED dimmer thiab LED teeb pom kev zoo
Kev koom tes ua haujlwm ntawm LED dimmer thiab LED teeb yog kom paub txog kev hloov kho qhov ci ntawm LED teeb los ntawm kev sib cuam tshuam. Hauv qab no yog cov lus qhia luv luv rau kev sib cuam tshuam ntawm LED dimmer thiab LED teeb.
1. PWM modulation
Nyob rau hauv PWM modulation hom, qhov ci ntawm LED teeb yog tswj los ntawm kev kho lub luag hauj lwm voj voog ntawm lub hwj chim mov voltage. Lub dimmer xa cov teeb liab hloov mus rau lub teeb ci LED, thiab lub teeb ci LED tso tawm lub teeb sib txawv raws li qhov sib txawv ntawm qhov sib txawv ntawm cov teeb liab hloov. Lub teeb liab hloov ntawm ob feem ntau yog raws li cov teeb liab digital, uas tuaj yeem paub txog kev tswj chaw taws teeb thiab dimming.
2. Voltage modulation
Hauv kev hloov pauv voltage, LED dimmer tswj lub teeb ci LED los ntawm kev tsav lub zog tawm ntawm LED teeb.
