Izindlela Ezinhlanu Zokufiphalisa Izibani ze-LED

Ukuze uthole ukukhanya, ukufiphala kubaluleke kakhulu.Ukufiphala akukwazi nje ukudala isimo esinethezekile, kodwa futhi kwandise ukusebenziseka kwezibani.Ngaphezu kwalokho, emithonjeni yokukhanya ye-LED, ukufiphala kulula ukukubona kunezinye izibani ze-fluorescent, izibani zokonga amandla, izibani ze-sodium ezinomfutho ophezulu, njll., kufanelekile kakhulu ukwengeza imisebenzi yokufiphala ezinhlotsheni ezahlukene zamalambu e-LED.Yiziphi izinhlobo zezindlela zokufiphalisa isibani esinazo?

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

I-FCP eyokusebenzisa izintambo ezilawulekayo, kusukela endaweni ehlobene ye-AC engu-0, ukunqanyulwa kwe-voltage okokufaka, kuze kube yilapho izintambo ezilawulekayo sezixhunyiwe, akukho okokufaka kwe-voltage.

Umgomo ukulungisa i-engeli yokuqhuba yegagasi ngalinye elinguhhafu wegagasi elishintshayo ukuze kushintshwe i-waveform ye-sinusoidal, ngaleyo ndlela kuguqule inani elisebenzayo lamanje elishintshayo, ukuze kufezwe injongo yokufiphala.

Izinzuzo:

izintambo ezikahle, izindleko eziphansi, ukunemba okuphezulu kokulungiswa, ukusebenza kahle okuphezulu, usayizi omncane, isisindo esilula, nokulawula kude okulula.Ibusa imakethe, futhi imikhiqizo eminingi yabakhiqizi ilolu hlobo lwe-dimmer.

Ububi:

ukusebenza kabi kokufiphalisa, ngokuvamile okubangela ukuncishiswa kwebanga lokufiphaza, futhi kuzobangela ubuncane bomthwalo odingekayo weqe amandla alinganiselwe enombolo eyodwa noma encane yezibani ezikhanyisayo ze-LED, ukuguquguquka okuphansi nokuhambisana okuphansi.

2.trailing edge cut (RPC) MOS tube dimming

I-trailing-edge phase-cut control dimmers ezenziwe nge-field-effect transistor (FET) noma amadivayisi we-insulated-gate bipolar transistor (IGBT).Ama-dimmers anqunyelwe unqenqema onqenqemeni ngokuvamile asebenzisa ama-MOSFET njengamadivayisi okushintsha, ngakho abuye abizwe ngokuthi ama-MOSFET dimmers, aziwa ngokuthi "amashubhu e-MOS".I-MOSFET iyiswishi elawulwa ngokugcwele, engalawulwa ukuthi ivulwe noma ivalwe, ngakho-ke akukho okwenzekayo ukuthi i-thyristor dimmer ayikwazi ukuvalwa ngokuphelele.

Ukwengeza, i-dimming circuit ye-MOSFET ifaneleka kakhulu ekufiphaleni komthwalo we-capacitive kune-thyristor, kodwa ngenxa yezindleko eziphezulu kanye nesifunda sokufiphalisa esiyinkimbinkimbi, akulula ukuzinza, ukuze indlela yokufiphalisa ishubhu ye-MOS ayikasungulwa. , kanye ne-SCR Dimmers isabala inani elikhulu lemakethe yesistimu yokufiphala.

3.0-10V DC

0-10V dimming kubuye kubizwe ngokuthi 0-10V isignali dimming, okuyindlela yokufiphalisa analogi.Umehluko wayo ku-FPC ukuthi kunezindawo ezimbili zokuhlangana ze-0-10V (+10V kanye -10V) kugesi we-0-10V.Ilawula ukuphuma kwamandla kagesi ngokushintsha i-voltage engu-0-10V.Ukufiphala kufinyelelwe.Ikhanya kakhulu uma ingu-10V, futhi ivaliwe uma ingu-0V.Futhi i-1-10V iyi-dimmer kuphela engu-1-10V, lapho i-dimmer yokumelana ilungiswa ku-1V encane, ukukhishwa kwamanje kungu-10%, uma okukhiphayo kungu-100% ku-10V, ukukhanya kuzoba ngu-100%.Kuyaphawuleka futhi into engcono kakhulu yokuhlukanisa ukuthi i-1-10V ayinawo umsebenzi wokushintshwa, futhi isibani asikwazi ukulungiswa ezingeni eliphansi kakhulu, kuyilapho i-0-10V inomsebenzi wokushintsha.

Izinzuzo:

umphumela omuhle wokufiphala, ukuhambisana okuphezulu, ukunemba okuphezulu, ukusebenza kwezindleko eziphezulu

Ububi:

izintambo ezinzima (izintambo zidinga ukwandisa imigqa yesignali)

4. I-DALI (I-Digital Addressable Lighting Interface)

Izinga le-DALI lichaze inethiwekhi ye-DALI, okuhlanganisa umkhawulo wamayunithi angama-64 (anamakheli azimele), amaqembu ayi-16 nezigcawu eziyi-16.Amayunithi okukhanyisa ahlukene ebhasini le-DALI angahlelwa kalula ukuze akwazi ukulawula nokuphatha izigcawu ezahlukene.Empeleni, uhlelo lokusebenza olujwayelekile lwe-DALI lungakwazi ukulawula izibani ezingama-40-50, ezingahlukaniswa ngamaqembu angu-16, kuyilapho zikwazi ukucubungula ezinye izilawuli/izigcawu ngokuhambisana.

Izinzuzo:

Ukufiphalisa okunembile, isibani esisodwa nokulawula okukodwa, ukuxhumana okubili, okulungele ukubuza okufika ngesikhathi kanye nokuqonda isimo semishini nolwazi.Ikhono eliqinile lokulwa nokugxambukela Kukhona izivumelwano ezikhethekile nemithethonqubo, ethuthukisa ukusebenzisana kwemikhiqizo phakathi kwemikhiqizo ehlukene, futhi idivayisi ngayinye ye-DALI inekhodi ehlukile yekheli, engafinyelela ukulawula ukukhanya okukodwa ngempela.

Ububi:

amanani aphezulu kanye nokulungisa iphutha okuyinkimbinkimbi

5. DMX512 (noma i-DMX)

Imoduli ye-DMX isifinyezo se-Digital Multiple X, okusho ukudluliswa kwedijithali okuningi.Igama layo elisemthethweni yi-DMX512-A, futhi isixhumi esibonakalayo esisodwa singaxhuma eziteshini ezingama-512, ngakho-ke singakwazi ukwazi ukuthi le divayisi iyithuluzi lokufiphalisa lokudlulisela kwedijithali elinamashaneli afiphalisayo angu-512.Kuyi-chip yesekethe ehlanganisiwe ehlukanisa amasiginali okulawula njengokukhanya, ukugqama, kanye ne-chromaticity, futhi iwacubungule ngokuhlukana.Ngokulungisa i-potentiometer yedijithali, inani lezinga lokuphuma kwe-analogi liyashintshwa ukuze lilawule ukukhanya nemibala yesiginali yevidiyo.Ihlukanisa izinga lokukhanya libe amazinga angama-256 ukusuka ku-0 kuye ku-100%.Isistimu yokulawula ingabona u-R, G, B, izinhlobo ezingama-256 zamaleveli ampunga, futhi ibone umbala ogcwele ngempela.

Kuzinhlelo zokusebenza eziningi zobunjiniyela, kudingekile kuphela ukusetha umphathi omncane wokulawula ebhokisini lokusabalalisa ophahleni, ukuhlela kusengaphambili uhlelo lokulawula ukukhanya, ukuligcina ekhadini le-SD, bese ulifaka kumsingathi omncane wokulawula ophahleni. ukubona uhlelo lokukhanyisa.Ukulawula ukufiphala.

Izinzuzo:

Ukufiphala okunembile, imiphumela eguqukayo ecebile

Ububi:

Izintambo eziyinkimbinkimbi nokubhala ikheli, ukulungisa amaphutha okuyinkimbinkimbi

Sisebenza ngokukhethekile ngamalambu acimeka, uma ufuna ukwazi okwengeziwe ngamalambu nama-dimmers, noma uthenge ama-dimmers afakwe kuvidiyo, sicela.Xhumana nathi.
