Isikhathi sokuqala:Kunezinhlobo ezimbili zesikhathi sokuqalisa semishini yokukhanyisa ezemidlalo: ukuqala kweso kanye nokubambezeleka kokuqala, okudingeka kukhethwe ngokufanele ngokuya ngemibandela ethile yephrojekthi.
Impulse yamanje eminingi:Lapho isibani siqalwa, kuba khona umsinga omkhulu odlula umthamo olinganiselwe, obizwa ngokuthi i- impulse current.Isilinganiso se-impulse current kuya kokusebenza okulinganiselwe sibizwa ngokuthi i-impulse current multiple.Ukuba ncane kwevelu, kuba nomthelela omncane ohlelweni lokusabalalisa amandla, oluphephe ngokuqhathaniswa.Ngaphansi kwezimo ezijwayelekile, ukuqala ngokushesha kwe-LED sports lighting impulse current multiple kukhulu, cishe izikhathi ezingu-40;kuyilapho isiqalo esibambezelekile sedivayisi yokukhanyisa ezemidlalo isiphindaphinda samanje sincane, singaphansi kwezikhathi ezingu-2.Isibani se-metal halide sinesici sokuqala esibambezelekile, ngakho-ke umthelela waso wokuphindaphinda wamanje nawo uncane, ngokuvamile ungaphansi kwezikhathi ezi-2.
Izinga lokushintsha kwamandla kagesi akhanyayo:Le pharamitha ikhombisa izinga lomthelela womthombo wokukhanya okhanyisayo wezemidlalo ngokuchezuka kwe-voltage, futhi iyisilinganiso sezinga lokushintsha kokushintshashintsha okukhanyayo kuya kuzinga lokushintsha kwamandla kagesi.
Ukuhlolwa kubonise ukuthi ukukhanyisa kwezemidlalo kwe-LED kunezinga eliphansi lokushintsha kwamandla kagesi akhanyayo, okuyi-Δφ%/ΔU%.Uma i-voltage ingukuchezuka okuhle, khona-ke Δφ%/ΔU%=0.092, lapho i-voltage ingukuchezuka okuyinegethivu, bese kuba ngu-Δφ%/ΔU%=0.075.
Kodwa-ke, le nkomba yezibani ze-metal halide impofu futhi ayigculisi.Uma ukuchezuka kwe-voltage kulungile, Δφ%/ΔU%=38/10=3.8;lapho ukuchezuka kwe-voltage kunegethivu, khona-ke Δφ%/ΔU%=28/10=2.8.
Le nkomba yezibani ze-metal halide inkulu uma kuqhathaniswa, futhi ukuguqulwa kwamandla kagesi kunethonya elikhulu ekuguquguqukeni kwayo okukhanyayo.Inani lokukhanyisa kwe-LED lincane uma kuqhathaniswa, lingaphansi kuka-3% welambu lensimbi le-halide, okungukuthi, ukugeleza okukhanyayo kuhlala kungashintshile kububanzi obubanzi be-voltage, futhi inezici ezinhle ze-voltage.
I-THD:Ngenxa yokuthi amadivaysi okukhanyisa ezemidlalo ngokuvamile ayimithwalo yesigaba esisodwa, ama-harmonics ayingxenye yesithathu.Udinga ukukhunjuzwa, akufanele nje unake inkinga ye-harmonic yezibani nezibani, kodwa futhi nenkinga ye-harmonic yesistimu yokulawula, ikakhulukazi i-module dimming cishe ingabangela ukwanda kwama-harmonics.
Ukungalingani kwezigaba ezintathu:Le nkinga ayikona nje ukukhanya kwezemidlalo.Zonke izinto zikagesi zesigaba esisodwa zingase zibe nokungalingani komthwalo wezigaba ezintathu.Okokuqala, kuyadingeka ukuxazulula inkinga ekuklanyeni, ukusabalalisa ngokulinganayo umthwalo wesigaba esisodwa esigabeni sesithathu, futhi ugcine ibhalansi yomthwalo wezigaba ezintathu ngangokunokwenzeka ngaphansi kwezindlela ezihlukahlukene zokulawula.Okwesibili, zama ukugcina ukusebenza okulinganayo kwesigaba esisodwa okuthathu ngangokunokwenzeka ngesikhathi sokusebenza.
Izinga lokuvikela ngokumelene nokushaqeka kukagesi kwe-luminaire ye-LED:Izimpahla zokukhanyisa ezemidlalo zangaphandle kufanele zifakwe kusigaba sokuqala, futhi izibani zezemidlalo zasendlini zasendlini zingase zibe Class I noma II.Ukukhanyisa ngaphansi kwamanzi kufanele kusebenzise i-voltage elinganiselwe ye-AC engenkulu kuno-12V noma i-DC engekho ngaphezu kuka-30V.Izibani zeClass III.
Ukuvikelwa kwesekethe emfushane:Lokhu kuyimfuneko edingekayo futhi eyisisekelo, futhi kuwukucushwa okujwayelekile.
Ukuvikelwa kokulayisha ngokweqile:Lena imfuneko ekhethiwe.Kunconywa ukuthi kumiswe izindawo ezisezingeni eliphansi naphakathi;kunconywa ukuthi ungalungiseleli izindawo ezisezingeni eliphezulu, noma umise ukuvikela ukugcwala okungaphezulu okusebenza ngama-alamu.
Isivikelo sesenzo samanje esisele:izindawo ezisezingeni eliphansi zingase zimiswe, kunjalo, noma cha;izindawo ezisezingeni eliphakathi akufanele zimiswe, noma zimise ukuvikelwa kwesenzo samanje esisalelayo esisebenza ngama-alamu.
