Dab tsi yog LED Dimmer Tsav Tsheb?

Txij li cov LEDs xav tau ncaj qha tam sim no thiab tsis tshua muaj hluav taws xob ua haujlwm, tus tsav tsheb ntawm LED yuav tsum tau hloov kho kom tswj tau cov hluav taws xob uas nkag mus rau LED.
LED tsav tsheb yog ib qho khoom siv hluav taws xob uas tswj cov hluav taws xob thiab tam sim no los ntawm lub zog hluav taws xob kom cov LEDs tuaj yeem ua haujlwm nyab xeeb thiab zoo. Tus tsav tsheb LED hloov pauv qhov hloov pauv tam sim no (AC) cov khoom siv los ntawm lub ntsiab mus rau qhov tam sim no ncaj qha (DC) vim tias cov khoom siv hluav taws xob feem ntau khiav ntawm lub mains.
LED tuaj yeem ua kom dim tau los ntawm kev hloov pauv tus tsav tsheb LED, uas yog tus saib xyuas kev tswj hwm tus nqi tam sim no uas nkag mus rau LED. Qhov kev hloov kho LED tsav tsheb no, qee zaum hu ua tus tsav tsheb LED dimmer, hloov kho lub teeb ci LED.
Nws yog ib qho tseem ceeb uas yuav tau xav txog tus tsav tsheb LED dimmer qhov yooj yim ntawm kev siv thaum mus yuav khoom rau ib qho. Tus tsav tsheb LED dimmer nrog dual in-line pob (DIP) hloov mus rau pem hauv ntej ua rau nws yooj yim rau cov neeg siv hloov cov zis tam sim no, uas hloov pauv qhov ci ntsa iab.
Compatibility ntawm LED dimmer tsav nrog Triode rau Alternating Tam sim no (TRIAC) phab ntsa daim hlau thiab lub hwj chim mov yog lwm feature los xyuas. Qhov no tau lees tias koj tuaj yeem tswj hwm cov hluav taws xob ceev ceev uas ntws mus rau hauv LED thiab tias koj lub dimmer yuav ua haujlwm rau txhua qhov haujlwm uas koj xav tau.

Ob txoj kev los yog kev teeb tsa yog siv los ntawm LED dimmer tsav los tswj cov hluav taws xob tam sim no uas nkag mus rau LED: amplitude modulation thiab mem tes dav modulation.

Txo tus nqi ntawm cov thawj coj tam sim no dhau los ntawm LED yog lub hom phiaj ntawm pulse width modulation, lossis PWM.
Tus neeg tsav tsheb ib ntus tig qhov tam sim no rau thiab tawm thiab rov qab rau dua los tswj cov nqi hluav taws xob tam sim no ntawm LED, txawm tias tam sim no nkag mus rau LED tseem nyob tas li. Raws li qhov tshwm sim ntawm qhov kev sib pauv luv luv no, lub teeb pom kev zoo ua dimmer thiab flickers imperceptibly sai heev rau tib neeg pom.

Txo cov hluav taws xob tam sim no mus rau hauv LED yog hu ua amplitude modulation, lossis AM. Dimmer teeb pom kev zoo tshwm sim los ntawm kev siv lub zog tsawg dua. Hauv cov hlab ntsha zoo sib xws, qhov txo qis tam sim no ua rau qis qis thiab ua kom muaj kev ua tau zoo ntawm LED. Flicker kuj raug tshem tawm nrog lub tswv yim no.
Txawm li cas los xij, nco ntsoov tias kev siv txoj kev dimming no ua rau muaj kev phom sij ntawm kev hloov pauv cov xim ntawm LED, tshwj xeeb tshaj yog nyob rau theem qis.

Tau txais LED dimmable tsav tsheb yuav ua rau koj tau txais txiaj ntsig tshaj ntawm koj lub teeb pom kev zoo LED. Ua kom zoo dua ntawm kev ywj pheej los hloov qhov ci ntsa iab ntawm koj lub LEDs kom txuag tau lub zog thiab muaj lub teeb pom kev zoo tshaj plaws hauv koj lub tsev.
Tiv tauj pebyog koj xav tau ib co LED sawb teeb nrog dimmer / dimmer dirver los yog lwm yam accessories.
