Qhov zoo ntawm SCR dimming
Txawm hais tias SCR dimming muaj ntau yam tsis txaus thiab teeb meem, nws muaj qee qhov zoo, uas yog, nws tau tsim kev sib koom tes nrog cov roj teeb halogen teeb, tuav lub lag luam loj dimming. Yog hais tias lub LED xav hloov txoj hauj lwm ntawm incandescent thiab halogen teeb nrog SCR dimming, nws yuav tsum tau sib xws nrog SCR dimming.
Tshwj xeeb, nyob rau qee qhov chaw uas SCR dimmable incandescent lossis halogen teeb tau teeb tsa, SCR dimming keyboards thiab pob qhov rooj tau teeb tsa rau ntawm phab ntsa, thiab ob qho tib si coj mus rau teeb tau teeb tsa kev sib txuas. Nws tsis yooj yim heev los hloov thyristor hloov ntawm phab ntsa thiab ua kom cov xov hlau txuas ntxiv. Txoj kev yooj yim tshaj plaws yog ua kom txhua yam tsis hloov pauv. LED qhov muag teev nrog lub teeb ua haujlwm yuav ua. Cov tswv yim zoo li no zoo ib yam li coj teeb fluorescent. Nws yog qhov zoo tshaj plaws los ua kom zoo ib yam li T10 thiab T8 fluorescent teeb tam sim no. Nws tsis xav tau tus kws tshaj lij hluav taws xob. Tib neeg tuaj yeem hloov nws ncaj qha. Yog li ntawd, ntau lub tuam txhab txawv teb chaws ntawm LED tsav ICs tau tsim ICs uas tau sib xws nrog thyristor dimming uas twb muaj lawm.
Qhov sib txawv nrog cov dav dav flyback IC yog tias lawv tuaj yeem kuaj xyuas lub kaum sab xis ntawm lub thyristor los txiav txim siab txog LED tam sim no rau dimming. Peb yuav tsis qhia lawv cov qauv kev ua haujlwm thiab kev ua haujlwm kom ntxaws vim peb xav tias qhov no yog cov kev taw qhia ntawm LED dimming.
