Iindlela ezintlanu zokuMfiphaza kwezibane ze-LED

Ukukhanya, ubumnyama kubaluleke kakhulu.Ukukhanya akukwazi nje ukudala umoya okhululekileyo, kodwa nokwandisa ukusetyenziswa kwezibane.Ngaphezu koko, kwimithombo yokukhanya ye-LED, ukufiphala kulula ukuyiqonda kunezinye izibane ze-fluorescent, izibane zokonga amandla, izibane ze-sodium ezinoxinzelelo oluphezulu, njl., ifaneleke ngakumbi ukongeza imisebenzi yobumnyama kwiindidi ezahlukeneyo zezibane ze-LED.Zeziphi iintlobo zeendlela zokufiphaza esinazo isibane?

I-1.Leading edge phase cut control dimming (FPC), eyaziwa ngokuba yi-SCR dimming

I-FCP kukusebenzisa iingcingo ezilawulekayo, ukusuka kwindawo ye-AC yesalamane engu-0, ukunqunyulwa kombane wegalelo, de iingcingo ezilawulekayo zidityanisiwe, akukho galelo lamandla ombane.

Umgaqo-siseko kukulungelelanisa i-angle ye-conduction yesiqingatha-amaza okutshintshana ngokutshintshayo ukutshintsha i-waveform ye-sinusoidal, ngaloo ndlela iguqula ixabiso elisebenzayo le-alternating current, ukuze kufezekiswe injongo yokunciphisa.

Izinto eziluncedo:

i-wiring efanelekileyo, ixabiso eliphantsi, ukuchaneka kohlengahlengiso oluphezulu, ukusebenza kakuhle okuphezulu, ubungakanani obuncinci, ubunzima obulula, kunye nokulawula kude.Ilawula imarike, kwaye uninzi lweemveliso zabenzi bolu hlobo lwe-dimmer.

Izinto ezingeloncedo:

ukusebenza kakubi kwe-dimming, ngokuqhelekileyo kubangele ukuncipha koluhlu lwe-dimming, kwaye kuya kubangela ukuba ubuncinane bomthwalo ofunekayo ugqithise amandla alinganisiweyo omnye okanye inani elincinci lezibane zokukhanyisa i-LED, ukuguquguquka okuphantsi kunye nokuhambelana okuphantsi.

2.trailing edge cut (RPC) MOS tube dimming

I-trailing-edge phase-cut control dimmers ezenziwe nge-field-effect transistor (FET) okanye izixhobo ze-bipolar transistor (IGBT) ezifakwe kwi-insulated-gate.I-trailing edge phase-cut dimmers ngokubanzi zisebenzisa ii-MOSFETs njengezixhobo zokutshintsha, ke zikwabizwa ngokuba zii-MOSFET dimmers, ezaziwa ngokuba "ziityhubhu zeMOS".I-MOSFET sisitshixo esilawulwa ngokupheleleyo, esinokulawulwa ukuba sivule okanye sivaliwe, ngoko akukho nto inokwenzeka ukuba i-thyristor dimmer ayikwazi ukucima ngokupheleleyo.

Ukongeza, i-mosFET dimming circuit ifaneleke ngakumbi kwi-capacitive load dimming kune-thyristor, kodwa ngenxa yeendleko eziphezulu kunye nesekethe ye-dimming enzima, akukho lula ukuzinza, ukwenzela ukuba indlela ye-MOS ye-tube dimming ayizange iphuhliswe. , kunye ne-SCR Dimmers isazibalela uninzi lwenkqubo ye-dimming market.

3.0-10V DC

Ukuncipha kwe-0-10V kukwabizwa ngokuba yi-0-10V ukuncipha komqondiso, okuyindlela yokuncipha kwe-analog.Umahluko wayo kwi-FPC kukuba kukho i-interfaces ezimbini ezingaphezulu ze-0-10V (+10V kunye ne-10V) kwi-0-10V yombane.Ilawula imveliso yangoku yamandla ombane ngokutshintsha i-voltage ye-0-10V.Ukufiphala kuphunyeziwe.Iqaqamba kakhulu xa iyi-10V, kwaye iyacima xa ingu-0V.Kwaye i-1-10V yi-dimmer kuphela yi-1-10V, xa i-dimmer yokumelana ihlengahlengiswa kwi-1V encinci, imveliso yangoku yi-10%, ukuba imveliso yangoku yi-100% kwi-10V, ukukhanya kuya kuba yi-100%.Kuyafaneleka ukuba uqaphele kwaye into engcono kakhulu yokwahlula kukuba i-1-10V ayinayo umsebenzi wokutshintsha, kwaye isibane asikwazi ukulungiswa kwinqanaba eliphantsi, ngelixa i-0-10V inomsebenzi wokutshintsha.
