Cia Peb Tham Txog Cov Dimming Txoj Kev Teeb Ntawm Cov Teeb Teeb (LED)
Raws li lub teeb ci, LED dimming yog ib qho tseem ceeb heev. Tsis yog tsuas yog ua kom tau ib qho chaw zoo nyob hauv lub tsev, hnub no, txo cov teeb uas tsis tsim nyog, thiaj li yuav ua tiav lub hom phiaj ntawm kev txuag hluav taws xob thiab txo cov emission tseem ceeb dua. Thiab rau cov teeb ci LED, dimming yog yooj yim mus cuag dua li lwm cov roj fluorescent, lub teeb txuag hluav taws xob, cov roj teeb ntsev thiab kom nyob rau ntawd, yog li peb yuav tsum tau ntxiv qhov ua kom tsis muaj teebmeem rau ntau hom LED teeb.
Dimming txoj kev teeb pom kev zoo ntawm cov teeb cig feem ntau muaj xws li: hloov dimming, thyristor dimming, analog dimming thiab PWM dimming. Ntawm no yog ib nyuag sib tham txog cov yam ntxwv ntawm cov kev ua kom tsis zoo no.
Hloov qhov tsis sib haum yog kom dim ntawm lub teeb los ntawm lub hwj huam hloov ntawm thawj lub teeb. Thaum siv thiab txhim kho, tsis muaj dimmer ntxiv. Tsuav tus naj npawb thiab kev hloov ntawm qhov tseem fais fab hloov siab tsis tu ncua, lub dimming ntawm lub teeb pom kev zoo yuav ua tiav kom tau raws li qhov sib txawv ntawm qhov kev xav tau ntawm tus kheej kev xav tau.
Qhov no dimming method yog tus nqi qis tshaj nyob rau hauv tag nrho cov kev txiav txim. Nws yuav siv tau ntev li ntev li qhov hloov qhov tsis hloov tsis tau hloov, tsis muaj lwm qhov nqi hluav taws xob.
Qhov tsis zoo ntawm kev hloov yooj yim tsis muaj teeb meem yog tias lawv tuaj yeem kho qhov sib txawv ntawm peb lossis plaub ntu, thiab kho tsis tau ib qho teeb meem zoo li linear dimming.
Thyristor dimmer feem ntau yog siv los ntawm kev hloov cov thawj hwj huam hloov nrog thyristor dimmer hloov, uas muaj peev xwm ua tau ntau yam kev ci ntsa iab los ntawm txoj kab npoo ntawm dimmer.
Qhov dimming txoj kev no muaj qhov zoo ntawm simplicity, ua tau thiab qhov nqi tsawg. Nws tsuas xav tau ntxiv ib qho kev sib txawv ntawm silicon dimmer, uas yog qhov feem nrov dimming method ntawm tam sim no.
Analog dimming: Thaum qhov kev sib txuas ntawm analog dimming, yuav tsum muaj 1-10V dimming hloov, thiab muaj cov kab 1-10V dimming teeb kab txuas nrog rau hauv lub teeb rau tsav teeb ntawm lub teeb rau ntawm qhov teeb meem.
Txawm hais tias cov nyhuv nyom zoo tagnrho, nws yog qhov yooj yim rau kev txhim kho thaiv, uas yog qhov loj tshaj plaws kho ntawm lub dimming, uas ua rau nws tsis txaus siab rau nrov ntau ntau.
PWM dimming tseem hu ua digital dimming, nws tuaj yeem ua rau hauv wireless network los ntawm digital programming daim ntawv ntawm 0-100% dimming, dimming effect yog zoo heev, tag nrho tus nqi yog tus siab, yuav siv tau nyob rau hauv lub ntse ntsej muag nrog ntau dua cov kev cai.
Tam sim no, muaj pes tsawg tus roj teeb thiab lub zog txuag hluav taws xob ntau heev. Nws yog assumed tias siv cov fluorescent yaj nyob hauv Suav teb yog 1 billion (feem ntau ntsia hauv chaw ua hauj lwm, khw malls thiab factories). Cia li hais tias lub zog nruab nrab ntawm txhua lub teeb hluav taws xob yog 25W (cov hwj huam ntawm qhov teeb meem ntawm 1.2m T8 fluorescent teeb yog 36W, kev siv zog ntau dua 40W). Txawm li cas los xij, qhov tseeb ntawm cov hluav taws xob cov roj fluorescent tsawg tsawg, yog li ntawd nws yog kwv yees li 25W, haus 0.1 degree ib hnub thiab 36.5 degrees ib xyoos twg. Excluding cov hnub so, nws muaj 30 degree. Ib billion yog 30 billion degrees. Nws yog peev xwm kom txuag tau yam tsawg kawg ntawm ib nrab ntawm lub zog tom qab hloov mus rau ib lub teeb taws, uas yog, 15 billion degrees. Kev siv tsis zoo tuaj yeem txuag tsawg kawg 10% zog, uas yog, 1.5 billion degrees. Raws li qhov muab xam rau ntawm 0.7 yuan ib kilowatt teev, nws yuav cawm 1.05 billion yuan.
Tus ntawd yog tus naj npawb zoo heev! Tus xov tooj no tsis suav nrog lub zog txuag hluav taws xob ntawm lub zog txuag hluav taws xob thiab cov roj teeb hluav taws xob uas yuav hloov los ntawm LED. Yog li ntawd, maj mam tsim lub zog-txuag adaptive dimming yog qhov tseem ceeb ntawm LED dimming!
