Chii chinonzi kuramba kuchimanikidza?Constant current inoreva kukosha kwemazuva ano kunotsanangurwa panguva yekugara kwekugadzirwa kwekugadzirwa mukati memamiriro ekushanda anobvumirwa emotokari IC;Constant voltage inoreva kukosha kwevoltage inotsanangurwa panguva yekugara yakabuda dhizaini mukati menzvimbo inotenderwa yekushanda yekutyaira IC.Kuratidzwa kwe LED kwaigara kuchifambiswa nemagetsi anogara aripo kare.Nekuvandudza tekinoroji, yekugara voltage drive inotsiviwa zvishoma nezvishoma neinongogara iripo drive.Kuyerera kwakananga kunogadzirisa kukuvadza kunokonzerwa nekusawirirana kwemazuva ano kuburikidza nekupikisa paunenge uchityaira pasi pekumanikidzwa nguva dzose kunokonzerwa nekusagadzikana kwemukati kupikisa kweimwe LED tube core.Parizvino, LE inoratidza skrini inoshandisa inogara iripo dhiraivha.Constant current.Inogonawo kukamurwa kuva: 1. Static constant current drive.Iyi nzira yekuongorora inokodzera yekunze kuratidza skrini, uye kupenya kwayo kwakanyanya.Simba rinogara razvino dhiraivha rakakamurwa kuita 1/2,1/8,1/16.Kazhinji kutaura, tora 1/4 semuenzaniso.Kana magetsi achipa ikozvino kweminiti imwe, inoda kuongorora kana muminiti ino.Paavhareji, mwenje mumwe unongobatidzwa kwe1/4 sekondi.Dynamic inogara iripo inoshanda kune yemukati kuratidza, asi 1/2 yacho inoshandiswa semi yekunze kuratidza.
