Ose madhiraivha anogona kunge achigara aripo (CC) kana anogara aine voltage (CV), kana ese ari maviri. Ichi ndicho chimwe chezvinhu zvekutanga zvaunofanira kufunga mukuita kwako sarudzo. Iyi sarudzo ichagadziriswa neiyo LED kana module iwe yauchange uchimisikidza, iyo ruzivo rwekuti inogona kuwanikwa pane iyo LED's data sheet.
CHII CHINOGARA CHINOITIKA?
Nguva dzose ikozvino (CC) Dhirairi dze LED dzinochengetedza magetsi emagetsi nguva dzose mukati memagetsi emagetsi nekuve nemhepo inoshanduka. CC vatyairi kazhinji ndiyo inonyanya kufarirwa sarudzo yemasaiti eOD. CC LED madhiraivha anogona kushandiswa kune ega mabhuru kana cheni ye LED mune akateedzana. Mutsara unoreva kuti maLED ese akaiswa pamwe chete mumutsetse, kuitira kuti iyezvino iyerere kuburikidza neumwe neumwe. Izvo zvinokanganisa ndezvekuti, kana dunhu rakatyoka, hapana yako maLED anoshanda. Nekudaro ivo vanowanzo kupa zvirinani kutonga uye neinoshanda zvakanyanya system pane inogara magetsi
CHII CHINONZI CONSTANT VOLTAGE?
Constant voltage (CV) LED vatyairi magetsi emagetsi. Ivo vane seti voltage iyo yavanopa kune emagetsi wedunhu. Iwe waizoshandisa madhiraivhu eCV akatungamira kumhanyisa akawanda maLED mune akafanana, semuenzaniso matanda eLEM. CV magetsi emagetsi anokwanisa kushandiswa nemitsetse yeLED ine chazvino chidziviriro chinodzivisa, icho chinowanzoitwa. Iko kuburitsa kwemagetsi kunofanirwa kusangana nemhepo inodiwa yeiyo tambo ye LED.
Vatyairi veCV vanogona zvakare kushandiswa emwenje mwenje enjini ine mutyairi IC mubhodhi.
NDINGASHANDISA RINI CV KANA CC?
Mazhinji ezvigadzirwa zveTauras anogara aine magetsi magetsi. Iyo inokodzera kutungamira marobhu emwenje, zviratidzo zvemwenje, girazi kuvhenekesa, Stage Mwenje, yekuvaka mwenje, mwenje wemwenje uye zvichingodaro.
