Los ntawm kev kho lub zog tsav ntawm cov nqaij qaib coop tshwj xeeb teeb, cov nyhuv dimming ntawm qaib coop tshwj xeeb teeb tuaj yeem pom tau. Txij li thaum lub ci ci ntawm cov nti thiab cov tsav tsheb tam sim no muaj qhov sib piv ruaj khov.
Dimming feem ntau hu ua mimicking dimming hom lossis linear dimming. Qhov no hom qaib coop tshwj xeeb teeb dimming, thaum tsav tsheb tam sim no nce los yog txo qis, nws yuav txo tau cov nti ntawm cov qaib coop tshwj xeeb teeb, thiab kev tiv thaiv ntawm kev tswj Circuit Court yog muaj zog ntawm overshoot nyhuv ntawm kev tsav tsheb tam sim no.
Qhov thib peb txoj kev dimming yog lub teeb pulse regulator, uas yog tswj lub square tsav tam sim no, hloov pauv mem tes dav, thiab tom qab ntawd hloov lub sijhawm tom qab kho lub mem tes dav, thiab tseem tuaj yeem ua tiav cov teebmeem txuag hluav taws xob tib lub sijhawm raws li cov zis. Raws li ib txwm muaj, qhov kev hloov pauv ceev ceev ntawm cov nqaij qaib coop tshwj xeeb teeb tuaj yeem khaws cia ntawm 200Hz ---1000Hz, uas yog khaws cia los ntawm tib neeg lub zeem muag, thiab tom qab ntawd tib neeg tsis tuaj yeem hnov qhov flickering ntawm lub teeb thiab cov txheej txheem ntawm kev txav mus los. Nws tuaj yeem txhim kho cov cua sov dissipation nyhuv ntawm qaib coop tshwj xeeb teeb.
Hauv cov ntsiab lus, txoj kev hloov kho ntawm cov qaib coop tshwj xeeb teeb yog raws li kev faib tawm tshwj xeeb ntawm cov tsav tam sim no tso zis tswj ntawm cov nqaij qaib coop tshwj xeeb teeb, thiab cov tswj Circuit Court kuj tuaj yeem muab faib ua analog tswj thiab PWM tswj, thiab tswj Circuit Court. yog ua tiav los ntawm kev tswj.
Tam sim no, nyob rau hauv lub tshav pob ntawm txoj kev teeb pom kev zoo, lub Scope ntawm kev siv cov nqaij qaib coop tshwj xeeb teeb yog kis tau sai heev, lub neej ntev kev pab cuam thiab txhim khu kev qha kev ua tau zoo tseem yog ib qho teeb meem ntawm kev xav, tab sis nrog rau kev txhim kho tas mus li thiab kev loj hlob ntawm technology, thaum muaj teeb meem ntawm kev pab cuam lub neej thiab kev ntseeg tau raug daws kom zoo, rau qee qhov, cov txheej txheem kev teeb pom kev zoo ntawm cov qaib coop tshwj xeeb teeb yuav inevitably txav mus rau qhov kev hloov kho ntse.
