Ixesha lokuqalisa:Kukho iintlobo ezimbini zexesha lokuqalisa kwizixhobo zokukhanyisa ezemidlalo: ukuqala kwangoko kunye nokulibaziseka kokuqala, okufuneka kukhethwe ngokufanelekileyo ngokwemiqathango ethile yeprojekthi.
Impulse yangoku yangoku:Xa isibane siqaliswa, kukho umsinga omkhulu odlula umbane olinganisiweyo, obizwa ngokuba yi-impulse current.Umlinganiselo we-impulse current kwi-rated current yokusebenza kuthiwa yi-multiple impulse current.Ixabiso elincinci, lincinci impembelelo kwinkqubo yokuhambisa amandla, ekhuselekileyo.Phantsi kweemeko eziqhelekileyo, ukuqala kwangoko kwezemidlalo ze-LED ze-impulse impulse yangoku zininzi, ziphezulu malunga namaxesha angama-40;ngelixa isiqalo sokulibaziseka kwesixhobo sokukhanyisa isixhobo se-impulse yangoku sincinci, singaphantsi kwamaxesha ama-2.Isibane se-metal halide sinophawu lokuqala olulibazisekileyo, ngoko ke impembelelo yaso yangoku iphinda-phinda incinci, ngokuqhelekileyo ingaphantsi kwamaxesha ama-2.
Umyinge wokutshintsha kwamandla ombane oLuminous Flux:Le parameter ibonisa iqondo lempembelelo yomthombo wokukhanya okukhanyisa ezemidlalo ngokutenxa kombane, kwaye ngumlinganiselo wesantya esikhanyayo sokutshintsha kwesantya sokutshintsha kombane.
Iimvavanyo zibonise ukuba ukukhanya kwezemidlalo ye-LED kunomlinganiselo ophantsi wokutshintsha kwe-voltage flux ekhanyayo, eyi-Δφ% / ΔU%.Xa i-voltage i-positive deviation, ngoko Δφ% / ΔU% = 0.092, xa i-voltage i-negative deviation, ngoko Δφ% / ΔU% = 0.075.
Nangona kunjalo, esi sibonakaliso sezibane ze-metal halide zincinci kwaye azinelisekanga.Xa ukutenxa kombane kulungile, Δφ%/ΔU%=38/10=3.8;xa ukutenxa kombane kungalunganga, ngoko Δφ%/ΔU%=28/10=2.8.
Esi sibonakaliso sezibane ze-metal halide sikhulu, kwaye utshintsho lombane lunempembelelo enkulu kwi-flux yayo ekhanyayo.Ixabiso lokukhanya kwe-LED lincinci ngokwentelekiso, lingaphantsi kwe-3% yesibane se-metal halide, oko kukuthi, ukukhanya okukhanyayo kuhlala kungatshintshwanga kuluhlu olubanzi lwamandla ombane, kwaye ineempawu zombane ezilungileyo.
THD:Ngenxa yokuba izixhobo zokukhanyisa ezemidlalo ubukhulu becala ziyimithwalo yesigaba esinye, i-harmonics ikakhulu yesithathu.Kufuneka kukhunjulwe, kungekhona kuphela kufuneka ingqalelo ingxaki harmonic izibane kunye nezibane, kodwa ingxaki harmonic yenkqubo yolawulo, ingakumbi imodyuli dimming kusenokwenzeka ukuba kubangele ukwanda harmonics.
Ukungalingani kwezigaba ezithathu:Le ngxaki ayikho kuphela kwizibane zezemidlalo.Zonke izixhobo zombane zesigaba esinye zinokuba nesigaba esithathu sokungalingani komthwalo.Okokuqala, kuyimfuneko ukusombulula ingxaki ekuyilweni, ukusabalalisa ngokulinganayo umthwalo wesigaba esisodwa kwisigaba sesithathu, kwaye ugcine ibhalansi yomthwalo wesigaba sesithathu kangangoko kunokwenzeka phantsi kweendlela ezahlukeneyo zokulawula.Okwesibini, zama ukugcina umsebenzi olungelelanisiweyo wesigaba esinye esithathu kangangoko kunokwenzeka ngexesha lokusebenza.
Inqanaba lokhuselo ngokuchasene nomothuko wombane we-luminaire ye-LED:Izibane zokukhanyisa ezemidlalo zangaphandle kufuneka zichazwe njengeKlasi I, kwaye izibane zezemidlalo zangaphakathi zinokuba ludidi I okanye lwe-II.Izibane zangaphantsi kwamanzi kufuneka zisebenzise amandla ombane e-AC angekho ngaphezulu kwe-12V okanye i-DC engekho ngaphezulu kwe-30V.Izibane zeClass III.
Ukhuseleko lwesekethe emfutshane:Oku kuyimfuneko kunye nesiseko esiyimfuneko, kwaye lubumbeko oluqhelekileyo.
Ukhuseleko lokulayisha ngaphezulu:Le yimfuneko ekhethiweyo.Kucetyiswa ukuba kumiselwe iindawo ezikwinqanaba elisezantsi neliphakathi;kucetyiswa ukuba ungacwangciswanga kwiindawo eziphezulu, okanye umise ukukhuselwa komthwalo ogqithisileyo osebenza kwii-alamu.
Ukhuseleko lwangoku olushiyekileyo:iindawo ezinomgangatho ophantsi zinokusekwa, ngokuqinisekileyo, okanye akunjalo;iindawo ezikumgangatho ophakathi akufanele zisekwe, okanye zisete ukhuseleko lwangoku olushiyekileyo olusebenza kwii-alamu.
