Tsis tu ncua voltage powers muab ib tug ruaj hluav taws xob thiab sib txawv ntawm tam sim no mus rau LED. Tsis tu ncua powers muab ib tug ruaj tam sim no thiab varythe hluav taws xob mus rau LED.
Ib yam li ntawd, tib neeg nug, qhov txawv ntawm qhov tam sim no thiab qhov hluav taws xob tsis tu ncua yog dab tsi?
Lub sij hawm tas li ” yog txheeb ze. Ib qhov chaw CCpower yuav tswj tau tam sim no ntawm ib qho tas li theem, tsis hais txog kev hloov pauv loj hauv hluav taws xob , thaum lub zog CV yuav tswj tau hluav taws xob ntawm ib qho tas li theem, tsis hais offairly loj hloov nyob rau hauv tam sim no.
Kuj Paub, dab tsi yog qhov hluav taws xob tsis tu ncua hluav taws xob? "CV" stands rau " tsis tu ncua voltage ", thiab "CC" sawv cev rau " tas li Tam sim no". Feem ntau hom load xav tau tsis tu ncua voltage ua haujlwm, yog li yog tias "CV" LED teeb, nws txhais tau tias PSU ua haujlwm zoo nrog koj lub nra. PSU muaj qhov txwv lub cev ntawm qhov nws muaj peev xwm tam sim no muab.
Dhau li ntawm no, dab tsi yog qhov voltage tsis tu ncua?
' Tsis tu ncua voltage ' yog hais txog lub peev xwm tofluctuate tso zis tam sim no los tswj cov txheej txheem hluav taws xob . Tsis tu ncua voltage tuaj yeem siv rau cov ntawv thov uas cov workpieces tsis muaj qhov chaw tiaj tus, xws li. hla cov xov hlau, thiab qhov twg qhov kev tiv thaiv sib txawv heev, thiab rau qhov luv luv welds (tsawg dua 1 millisecond).
Vim li cas LEDs xav tau qhov tam sim no?
Lub hom phiaj tseem ceeb ntawm tus tsav tsheb LED yog los kho qhov kev hloov hluav taws xob siab dua no tam sim no mus rau qhov tsawg voltagedirect tam sim no zog o LEDs yog tsim los tuav. LEDs yog tam sim no tsis tu ncua cov khoom siv nrog rau pem hauv ntej voltage poob.

Dab tsi yog qhov kev sib raug zoo ntawm lej ntawm qhov tam sim no tsis kam thiab voltage gizmo?
Ohm txoj cai. Kev sib raug zoo ntawm qhov hluav taws xob, tam sim no, thiab kev tiv thaiv tau piav qhia los ntawm Ohm txoj cai. Qhov kev sib npaug no, i = v / r, qhia peb tias tam sim no, i, ntws los ntawm Circuit Court yog ncaj qha proportional rau qhov voltage, v, thiab inversely proportional to the resistance, r
Dab tsi yog qhov txawv ntawm qhov tam sim no thiab cov khoom siv tam sim no?
Kev khiav ntawm electrons yog hu ua electron tam sim no. Electrons ntws los ntawm qhov tsis zoo terminal mus rau qhov zoo. Pa tam sim no los yog tam sim no yooj yim, coj zoo li cov neeg nqa khoom muaj txiaj ntsig ua rau tam sim no ntws. Pa tam sim no ntws los ntawm qhov zoo davhlau ya nyob twg mus rau qhov tsis zoo
Dab tsi yog qhov txawv ntawm kev tswj thiab qhov tsis tu ncua hauv kev tshawb fawb?
Qhov sib txawv ntawm qhov tsis tu ncua thiab Tswj Ib qhov hloov pauv tsis tu ncua tsis hloov. Ib qho kev tswj hwm qhov sib txawv ntawm lwm qhov kev hloov pauv, tab sis txhob txwm ua kom tas mus li thoob plaws qhov kev sim kom qhia txog kev sib raug zoo ntawm kev vam thiab kev ywj pheej
Tam sim no voltage thiab tsis kam yog dab tsi?
Peb lub hauv paus ntsiab lus ntawm qhov kev qhia no tuaj yeem piav qhia siv cov khoom siv hluav taws xob, lossis tshwj xeeb tshaj yog, tus nqi lawv tsim: Voltage yog qhov sib txawv ntawm tus nqi ntawm ob lub ntsiab lus. Tam sim no yog tus nqi uas tus nqi ntws. Resistance yog ib yam khoom nyiam los tiv thaiv tus nqi ntws (tam sim no)
