Uma umthombo wokukhanya omusha ungena emakethe, inkinga ye-stroboscopic nayo yavela. U-Miller I we-PNNL uthe: Ubukhulu bokukhanya okukhipha ukukhanya kwe-LED bukhulu nakakhulu kunokwelambu le-incandescent noma isibani se-fluorescent. Kodwa-ke, ngokungafani namalambu e-HID noma amalambu e-fluorescent, ukukhanya kwe-solid state SSL kuyidivayisi ye-DC, okusho ukuthi lapho kunikezwa amandla amanje, i-LED ingakhanyiswa ngaphandle kokucwayiza.
Kulawo ma-circuits e-LED alula angasebenzisi idrayivu yokulungisa yamanje ehlukile, ukukhanya kwe-LED kuzoshintsha ngomjikelezo wamanje oshintshanayo. Idrayivu idlala izindima ezimbili, ukunikezwa kwamandla kanye nokulungisa. Inqubo yokuguqula isuke ekushayeleni iye ku-LED, ukushintshana kwamanje kuya koqondile kuzokhiqiza ama-voltage kanye namaribholi amanje aphumayo. Lolu hlobo lwe-ripple lukhona ngokuphindwe kabili i-voltage yokuhlinzeka, engu-120H e-United States. Kunobudlelwano obuhambisanayo phakathi kokuphumayo kwe-LED kanye ne-waveform ephumayo yedrayivu. Ukufiphala kungenye imbangela yokucwayiza. Ama-dimmers endabuko, afana nama-TRIAC dimmers (ingxenye ye-elekthronikhi engakwazi ukuqhuba ukuqhutshwa kwezindlela ezimbili), lungisa okwamanje futhi unciphise ukuphuma kokukhanya ngokunweba isikhathi sokuvala phakathi nomjikelezo wokushintsha. Kuma-LED, kuhle ukusebenzisa i-pulse width modulation (PWM) ukushintsha ama-LED kumafrikhwensi angaphezu kuka-200 Hz. Nokho, u-Benya ugcizelele: "Uma usebenzisa ukuguquguquka kobubanzi be-pulse nge-frequency ephansi kakhulu, njenge-frequency evamile yokunikezwa kwamandla, kuzobangela ukucwayiza okuphezulu kakhulu."
Ukuhlaziywa komqondo ojwayelekile we-LED stroboscopic:
Kukhona izinto ezine ezingenza ukuthi umthombo wokukhanya we-LED ulokoze noma uvule futhi uvale.
1) Ubuhlalu besibani se-ED abufani nogesi wokushayela we-LED, futhi ubuhlalu obujwayelekile obubodwa obungu-1W bumelana namanje: 280-30mA.
I-Voltage: 3.0-3.4V, uma i-chip yesibani ingenawo amandla anele, izobangela ukuthi umthombo wokukhanya ucwayize, futhi owamanje uphezulu kakhulu.
Uma yamukelwe, izovula futhi ivale. Ezimeni ezibucayi, intambo yegolide noma intambo yethusi eyakhelwe kubuhlalu besibani izoshiswa, okubangele ukuthi ubuhlalu besibani bungakhanyi.
2) Kungenzeka ukuthi amandla okushayela aphukile, inqobo nje uma eshintshwa ngomunye ugesi omuhle wokushayela, ngeke akhanyise.
3) Uma umshayeli enomsebenzi wokuvikela izinga lokushisa elingaphezu kokushisa, futhi ukusebenza kokushisa kokushisa kwesibani akukwazi ukuhlangabezana nezidingo, ukuvikelwa kokushisa okuphezulu komshayeli kuqala.
Kuzoba khona into ekhanyayo futhi ekhanyayo uma kusebenza, isibonelo: Izindlu ze-floodlight ezingu-20W zisetshenziselwa ukuhlanganisa amalambu angu-30W, akukho msebenzi wokukhipha ukushisa. Kuyoba kanje uma kwenziwa.
I-4) Uma isibani sangaphandle sinesimo sokukhanyisa nokucisha, khona-ke isibani sizogcwala futhi umphumela uzokhanya futhi ngeke uvule. Ubuhlalu bezibani nomshayeli bazophulwa. Vele umiselele umthombo wokukhanya.
Indlela yokunciphisa i-stroboscopic
Ukhiye wokunciphisa ukucwayiza kwe-stroboscopic ukushayela, okungaxazululwa ngokunikeza umsinga ongaguquki, ongaguquki. Kodwa-ke, abakhiqizi kufanele balinganise ezinye izici ukushayela izindleko, usayizi, ukwethembeka nokusebenza kahle lapho besekela imikhiqizo ye-LED. URee umelwe nguMark McClear, iphini likamongameli wezobunjiniyela. Ukusetshenziswa okuhlosiwe kwe-luminaire nakho kudinga ukucatshangelwa ukuze kuqinisekiswe ukuthi umkhiqizo awuklanyelwe ngokweqile, ngoba kwezinye izimo zokukhanyisa i-stroboscopic flicker iyamukeleka, kanti enye ayimukeleki. UMcclear uphinde wathi: "Abakhiqizi bebelokhu bezama ukukhulisa ukuthi yimiphi imikhiqizo elungele ukuthi yiziphi izinhlelo zokusebenza, kanye nendlela yokwenza i-strobe yamukeleke ngaphandle kokunyusa izindleko." Ama-Capacitor angakwazi ukulungisa i-AC ripple esuka kumshayeli iye ku-LED, kodwa futhi inobubi, kusho uBenya. Ama-Capacitor makhulu futhi ayazwela lapho kushisa". Ngakho-ke, endaweni ehlangene futhi enomkhawulo, njengomthombo wokukhanya oshintshwayo we-LED, ukusetshenziswa kwama-capacitor akusebenzi. Besebenzisa ama-LED alungisekayo we-pulse wide modulation (PWM), abakhiqizi bangalungisa lamanje libe kakhulu. amaza aphezulu adlula ama-kilohertz amaningana Lokhu kufana ne-electronic ballasts eshayela izibani ze-fluorescent, ibanga eliseduze phakathi komshayeli ne-LED "Ngeshwa, abantu abaningi bafuna ukushayela kude nesistimu yokukhanyisa akwenzeki ngaso sonke isikhathi." Kusho u-Benya. Ukuze kwenziwe lula ukuhlolwa kokuhambisana phakathi kwezinjini zokukhanya ze-LED nezingafiphala (izinjini zokukhanya ze-LED), i-EMA (National Electrica/Manufacturers Association) ikhiphe i-NEMA SSL7A-2013 "Solid State Lighting SSL Phase Cut Dimming : Ukuvumelana Okuyisisekelo ", lona umhlahlandlela wabaklami bemikhiqizo yokukhanyisa nabakhiqizi. Uma nje injini yokukhanya kwe-dimmer ne-LED ifinyelela izinga, iyahambisana. UMegan, umphathi wephrojekthi yezobuchwepheshe ye-NEMA, uthe leli zinga lingelokuqala embonini. futhi isayinwe ngabakhiqizi abakhulu abangama-24. Inhloso ye-SSL7A ukususa ukuhlolwa okufanayo kwamalambu nama-dimmers. Okufanele kugcizelelwe ukuthi leli zinga lisebenza kuphela kubuchwepheshe ngemva kokukhishwa kwezinga. Njengoba kushiwo, indinganiso ayinikezi indlela "yokunquma ukuhambisana kwemikhiqizo ekhona noma izinjini zokukhanya ze-LED ezifakiwe kanye nama-dimmers we-phase-cut".
