Tus tsav tsheb LED Dimmer yog dab tsi?

Vim tias cov LEDs xav tau hluav taws xob ncaj qha thiab qis voltage kom ua haujlwm, tus tsav tsheb ntawm LED yuav tsum tau kho kom tswj tau qhov hluav taws xob uas nkag mus rau hauv LED.
Tus tsav tsheb LED yog ib qho khoom siv hluav taws xob uas tswj qhov voltage thiab tam sim no los ntawm lub hwj chim kom cov LEDs tuaj yeem ua haujlwm tau zoo thiab muaj kev nyab xeeb. Tus tsav tsheb LED hloov qhov hluav taws xob hloov pauv (AC) los ntawm lub hwj chim loj mus rau lub hwj chim ncaj qha (DC) vim tias feem ntau cov khoom siv hluav taws xob khiav ntawm lub hwj chim loj.
Lub LED tuaj yeem ua kom dimmable los ntawm kev hloov tus tsav tsheb LED, uas yog tus saib xyuas kev tswj hwm qhov ntau ntawm cov hluav taws xob uas nkag mus rau hauv LED. Tus tsav tsheb LED no, qee zaum hu ua tus tsav tsheb LED dimmer, hloov kho qhov ci ntawm LED.
Thaum yuav ib lub LED dimmer driver, nws yog ib qho tseem ceeb uas yuav tsum xav txog qhov yooj yim siv ntawm lub LED dimmer driver. Lub LED dimmer driver uas muaj ob lub in-line package (DIP) switches nyob rau pem hauv ntej ua rau nws yooj yim rau cov neeg siv hloov cov zis tam sim no, uas ua rau qhov ci ntawm LED hloov pauv.
Qhov sib xws ntawm tus tsav tsheb LED dimmer nrog Triode rau Alternating Current (TRIAC) phab ntsa thiab lub zog muab hluav taws xob yog lwm yam uas yuav tsum kuaj xyuas. Qhov no lav tias koj tuaj yeem tswj tau qhov hluav taws xob ceev ceev uas ntws mus rau hauv LED thiab koj lub dimmer yuav ua haujlwm rau txhua qhov project uas koj muaj hauv siab.

Ob txoj kev lossis kev teeb tsa siv los ntawm cov tsav tsheb LED dimmer los tswj cov hluav taws xob uas nkag mus rau hauv LED: amplitude modulation thiab pulse width modulation.

Txo qhov ntau ntawm cov hluav taws xob uas hla dhau LED yog lub hom phiaj ntawm pulse width modulation, lossis PWM.
Tus tsav tsheb yuav qhib thiab kaw qhov hluav taws xob tas li thiab rov qhib dua kom tswj tau qhov hluav taws xob uas siv rau lub LED, txawm tias qhov hluav taws xob uas nkag mus rau hauv lub LED tseem nyob ruaj khov. Vim yog qhov kev sib pauv luv luv no, lub teeb yuav tsaus zuj zus thiab ci ntsa iab sai dhau rau tib neeg pom.

Kev txo cov hluav taws xob uas nkag mus rau hauv LED hu ua amplitude modulation, lossis AM. Lub teeb dimmer yog los ntawm kev siv zog tsawg dua. Ib yam li ntawd, cov hluav taws xob uas txo qis ua rau qhov kub qis dua thiab ua rau LED ua haujlwm tau zoo dua. Flicker kuj raug tshem tawm nrog txoj kev no.
Txawm li cas los xij, nco ntsoov tias kev siv txoj kev dimming no muaj qee qhov kev phom sij ntawm kev hloov pauv cov xim ntawm LED, tshwj xeeb tshaj yog thaum qis.

Kev tau txais cov tsav tsheb LED dimmable yuav ua rau koj tau txais txiaj ntsig zoo tshaj plaws ntawm koj lub teeb pom kev zoo LED. Siv qhov kev ywj pheej los hloov cov qib ci ntawm koj cov LEDs kom txuag hluav taws xob thiab muaj lub teeb pom kev zoo tshaj plaws hauv koj lub tsev.
