Iyini i-pressure drive eqhubekayo?I-Constant current ibhekisela enanini lamanje elishiwo ngesikhathi sokuklama okukhipha njalo ngaphakathi kwendawo yokusebenza evumelekile yedrayivu IC;I-voltage engaguquki isho inani lamandla kagesi elicaciswe ngesikhathi somklamo ophumayo ongashintshi ngaphakathi kwendawo yokusebenza evumelekile yedrayivu ye-IC.Isibonisi se-LED sasihlala siqhutshwa yi-voltage engaguquki ngaphambili.Ngokuthuthuka kobuchwepheshe, i-voltage drive engashintshi kancane kancane ithathelwa indawo yidrayivu yamanje.Ukugeleza okuqondile kuxazulula ukulimala okubangelwa ukungahambisani kwamanje ngokusebenzisa ukumelana lapho ushayela ngaphansi kwengcindezi eqhubekayo ebangelwa ukumelana okungahambisani kwangaphakathi kwe-tube core ngayinye ye-LED.Njengamanje, isikrini sokubonisa se-LE sisebenzisa idrayivu yamanje engashintshi.Amanje njalo.Ingase futhi ihlukaniswe: 1. Idrayivu yamanje emile.Le ndlela yokuskena ifanele isikrini sokubonisa sangaphandle, futhi ukukhanya kwayo kuphezulu kakhulu.Idrayivu yamanje yamandla engaguquki ihlukaniswe yaba ngu-1/2,1/8,1/16.Ngokuvamile, thatha 1/4 njengesibonelo.Uma ukunikezwa kwamandla kunikeza okwamanje iminithi elilodwa, idinga ukuskena izikhathi ezine kulo mzuzu.Ngokwesilinganiso, isibani esisodwa sikhanya kuphela isekhondi elingu-1/4.I-Dynamic constant current iyasebenza ekubonisweni kwasendlini, kodwa i-1/2 yayo isetshenziselwa ukubonisa ngaphandle kancane.
