Dab tsi yog qhov dimming LED vaj huam sib luag teeb?
Dimming LED vaj huam sib luag teeb yog ib hom vaj huam sib luag teeb nrog zoo illuminance uniformity, siab dua CRI, uniform thiab mos lub teeb. Dimming coj vaj huam sib luag lub teeb txhais tau tias qhov ci ntawm lub teeb tuaj yeem hloov kho. Feem ntau hais lus, muaj peb hom dimming txoj kev dimming coj vaj huam sib luag teeb.
Hom dimming LED vaj huam sib luag teeb
1. LED 0/1-10V dimming
{{0}}V dimming, kuj hu ua 0-10V teeb liab dimming, yog ib qho analog dimming txoj kev. Nws tswj cov zis tam sim no ntawm lub hwj huam mov los ntawm kev hloov qhov voltage ntawm 0-10V kom ua tiav dimming. Nws yog qhov ci tshaj plaws thaum nws yog 10V, thiab nws tawm thaum nws yog 0V. Rau 1-10V dimming, thaum qhov kev tiv thaiv dimmer hloov mus rau qhov tsawg kawg nkaus ntawm 1V, cov zis tam sim no yog 10 feem pua, thiab yog tias cov zis tam sim no yog 100 feem pua ntawm 10V, qhov ci kuj yuav yog 100 feem pua. 1-10V tsis muaj lub luag haujlwm ntawm qhov hloov pauv, thiab lub teeb tsis tuaj yeem hloov kho rau qhov ua haujlwm kaw qis tshaj plaws, thaum 0-10V muaj lub luag haujlwm ntawm kev hloov.
2. LED SCR dimming
SCR dimming tam sim no yog txoj kev dimming tshaj plaws. Nws yog lub cev muaj zog ntawm dimming. SCR dimmer muaj qhov zoo ntawm kev hloov kho qhov tseeb, kev ua haujlwm siab, me me, lub teeb yuag, thiab yooj yim rau kev khiav lag luam los ntawm qhov deb, thiab tseem muaj nyob hauv khw. Qhov zoo ntawm SCR dimming yog kev ua haujlwm siab, kev ua haujlwm ruaj khov thiab tus nqi qis dimming.
3. PWM dimming
PWM dimming tseem hu ua digital dimming. Txoj kev no hloov lub sijhawm ntawm lub sijhawm tam sim no los ntawm kev tig lub LED rau thiab tawm nrog PWM nthwv dej kom ua tiav cov txiaj ntsig ntawm kev hloov kho qhov ci. PWM yog cov txheej txheem zoo heev rau kev tswj cov analog circuits siv cov zis digital ntawm microprocessor. Ua li no, tus nqi thiab kev siv hluav taws xob ntawm qhov system tuaj yeem txo qis heev. PWM kho qhov ci ci los ntawm kev kho lub sijhawm piv ntawm lub teeb thiab tsaus.
Qhov zoo ntawm dimming coj vaj huam sib luag teeb
1. zog txuag & kev tiv thaiv ib puag ncig
Raws li ib puag ncig tus phooj ywg lub zog txuag lub teeb, LED dimming vaj huam sib luag lub teeb muaj cov txiaj ntsig zoo ib yam li lwm lub teeb hauv kev teeb pom kev zoo, muaj qhov ua tau zoo tshwj xeeb uas lub teeb ci tsis muaj - dimmable muaj nuj nqi, txawv ntawm lub teeb zoo tib yam, dimming LED vaj huam sib luag teeb pom kev zoo. rau kev siv dav dav ntxiv rau nws kuj tseem ua lub luag haujlwm zoo hauv kev txuag hluav taws xob thiab txo qis emission.
Xyoo 2016, lub teb chaws tag nrho cov hluav taws xob siv tau mus txog 5.9 trillion kw.h, uas tsuas yog cov teeb pom kev zoo hluav taws xob muaj txog 600 billion kw.h, yog tias peb siv LED vaj huam sib luag teeb lossis lwm lub teeb ci LED uas siv 1/3 tsawg zog los hloov cov kab lig kev cai teeb. , lub zog-txuag nyhuv yuav pom tseeb, yog li LED vaj huam sib luag teeb nrog dimming muaj nuj nqi yog nrov ntawm cov neeg siv khoom.
2. lub neej ntev
Lub tshuab dimming txo cov zis hluav taws xob, uas txhim kho qhov chaw ua haujlwm ntawm LED vaj huam sib luag teeb, ua kom lub neej ntev ntawm lub teeb thiab txhim kho nws txoj kev ntseeg tau. Qhov tseem ceeb cuam tshuam rau kev ntseeg tau ntawm LED vaj huam sib luag teeb yog qhov kub thiab txias.
Txawm hais tias nws yog LED fais fab mov lossis LED nti, qhov siab dua qhov kub thiab txias yog, qhov tsawg dua lub neej thiab kev ntseeg siab yuav yog. LED fais fab mov kev pab cuam lub neej yog mus txog 320, 000 teev nyob rau hauv 25 degree ambient kub, tab sis nws yuav sharply down mus rau tsuas yog 35,000 teev nyob rau hauv 60 degree ambient kub.
Nrog rau qhov kub siab dua, LED nti lub teeb tsis ua haujlwm kuj tseem nce ntxiv. LED teeb tsis ua hauj lwm zoo sib xws rau nws qhov sib txuas qhov kub thiab txias ntawm lub semiconductor PN hlws ris, siab dua qhov sib txuas kub, LED teeb qhov chaw yuav tshwm sim sai dua lub teeb tsis ua hauj lwm, uas txhais tau hais tias luv luv lifespan ntawm LED teeb.
Yog tias qhov ntsuas kub ntawm qhov sib txuas yog 105 degree, lub teeb ci LED tsuas yog ua haujlwm 10,000 teev thiab ci ntsa iab mus txog 70 feem pua; qhov sib txuas kub yog 95 degree, LED teeb tuaj yeem ua haujlwm 20, 000 teev; qhov sib txuas kub yog 75 degree, LED teeb yuav ua haujlwm 50, 000 teev; Thaum qhov kub ntawm qhov sib txuas yog 65 degree, lub teeb LED yuav ua haujlwm ntev li 90, 000 teev. Hauv lwm lo lus, tus yuam sij ntawm kev ncua LED lub teeb lifespan yog txo qhov kub ntawm qhov sib txuas.
Txais siv thev naus laus zis dimming, txo cov zis hluav taws xob, cov khoom siv hluav taws xob LED yuav txo qis nws tus kheej lub zog siv, thiab lub plhaub kub yuav poob rau tib lub sijhawm. Thaum lub ambient kub yog 25 degree thiab tag nrho load, lub plhaub kub yog 50 degree, tab sis thaum koj siv dimming tshuab los tswj cov zis rau tsuas yog 50 feem pua load, lub plhaub kub yuav poob mus rau 40 degree, kev pab cuam lub neej yuav ob npaug, kev ntseeg tau. tuaj yeem nce los ntawm 25 feem pua 40 feem pua.
