LED dej nyab teeb tuaj yeem ua tau zoo dua hauv kev kho kom zoo nkauj thiab toj roob hauv pes teeb pom kev zoo los ntawm dimming, thiab qhia cov yam ntxwv zoo nkauj.LED dej nyab teeb muaj lub kaum sab xis loj dua li cov teeb pom kev zoo, yog li lawv siv tau yooj yim dua.LED dej nyab lub teeb txais kev sib xyaw ua ke ntawm cov cua sov dissipation qauv tsim.Piv nrog rau cov qauv hluav taws xob hluav taws xob dav dav tsim, thaj chaw tshav kub dissipation yog nce los ntawm 80%, uas ua kom lub luminous efficiency thiab kev pab lub neej ntawm LED dej nyab teeb.

Thawj txoj kev yog kom ua tiav dimming los ntawm kev kho cov tsav tsheb tam sim no ntawm LED dej nyab teeb, vim tias qhov ci ntawm LED nti thiab LED tsav tam sim no muaj qhov sib npaug.

Qhov thib ob hom dimming feem ntau hu ua analog dimming hom lossis linear dimming.Qhov kom zoo dua ntawm qhov dimming no yog tias thaum tsav tsheb tam sim no nce lossis txo qis, LED nti yuav raug txo qis, thiab qhov kev hloov ntawm kev tsav tsheb tam sim no yuav muaj qee yam cuam tshuam rau xim kub ntawm LED nti.

Qhov thib peb yog los tswj cov tsav tsheb tam sim no kom square, thiab hloov lub zog tso zis tib lub sijhawm los ntawm kev kho cov mem tes dav.Thaum cov kev cai hloov ceev ceev feem ntau yog 200Hz txog 10kHz, tib neeg tsom iav tsis tuaj yeem ntes cov txheej txheem ntawm lub teeb hloov.Lwm qhov zoo dua yog tias cov cua sov dissipation zoo dua.Qhov tsis zoo yog tias qhov overshoot ntawm tus tsav tam sim no muaj qee yam cuam tshuam rau lub neej ntawm LED nti.

Peb siv LED teeb pom kev zoo los txiav txim seb cov teeb pom kev zoo raws li qhov pom ntawm lub teeb pom kev zoo, teeb pom kev zoo, teeb pom kev zoo, chaw teeb tsa thiab lwm yam.Sab nrauv kho kom zoo nkauj teeb pom kev zoo ntawm cov tsev yog qhia los ntawm qhov projection ntawm LED dej nyab teeb.Nyob rau hauv kev tsim ntawm LED dej nyab teeb, uas zoo kawg nkaus qhia cov yam ntxwv ntawm lub tsev.

Raws li qhov xav tau, kev tswj lub teeb ntawm LED dej nyab lub teeb yuav tsum tsawg dua 6 °.Lub teeb beam yog nqaim, thiab lub teeb tawg yog sib sau ua ke, yog li tsim lub tswv yim ntawm kev tswj lub teeb.LED dej nyab teeb yog tsuas yog siv rau cov teeb pom kev zoo nkauj thiab chaw ua lag luam teeb pom kev zoo.Cov khoom siv kho kom zoo nkauj yog hnyav dua.Vim tias cov cua sov feem ntau yuav tsum tau xav txog, muaj qee qhov sib txawv ntawm lawv cov tsos thiab cov teeb pom kev zoo ntawm LED..

Qhov ntawd yog tswj lub teeb ntawm lub kaum sab xis nqaim.Nws tuaj yeem txo cov teeb pom kev zoo yam tsis tau txo lub teeb.Vim tias nws tswj lub teeb thiab tuaj yeem mloog cov kab teeb ci ua ke, tsis muaj glare, nws yuav tsis cuam tshuam rau lub neej ntawm cov neeg nyob hauv txhua qhov.
