Ii-LED zi-Light Emitting Diodes: amacandelo e-elektroniki aguqula amandla ombane ngokuthe ngqo ekukhanyeni ngokuhamba kwee-electron ngaphakathi kwe-diode material.Ii-LED zibalulekile kuba, ngenxa yokusebenza kakuhle kunye nokusetyenziswa kwamandla aphantsi, ziye zaba yindawo yokukhanya okuqhelekileyo.
I-Surface Mounted Device (SMD) i-LED yi-1 ye-LED kwibhodi yesiphaluka, enokuthi ibe namandla aphakathi okanye amandla aphantsi kwaye ingabonakali kakhulu ekuveliseni ukushisa kune-COB (i-Chips On Board) LED.Ii-LED ze-SMD zihlala zixhonywa kwiBhodi yeNkonzo eprintiweyo (PCB), ibhodi yesekethe apho ii-LED zithengiswa ngoomatshini.Xa kusetyenziswa inani elincinci le-LED ezinamandla aphakamileyo, ukuhanjiswa kobushushu kule PCB akuthandeki.Kungcono ukusebenzisa i-LED yamandla aphakathi kuloo meko, kuba ubushushu buhlulwe ngcono phakathi kwe-LED kunye nebhodi yesekethe.Ibhodi yesekethe kufuneka nayo ilahlekelwe bubushushu.Oku kuphunyezwa ngokubeka iPCB kwiprofayile yealuminiyam.Umgangatho ophezulu weemveliso zokukhanyisa i-LED zineprofayili ye-aluminium ngaphandle ukwenzela ukuba ubushushu be-ambient bupholise isibane.Iintlobo ngexabiso eliphantsi zixhotyiswe ngengxowa yeplastiki, kuba iplastiki inexabiso eliphantsi kune-aluminiyam.Ezi mveliso zibonelela kuphela ukutshatyalaliswa kobushushu obuhle ukusuka kwi-LED ukuya kwiplate yesiseko.Ukuba i-aluminiyam ayilahlekelwa bubushushu, ukupholisa kuhlala kuyingxaki.
Umlinganiselo we-lumen nge-watt (lm/W) ubonisa ukusebenza kakuhle kwesibane.Ukuphakama kweli xabiso, amandla amancinci afunekayo ukuvelisa umlinganiselo othile wokukhanya.Nceda uqaphele ukuba eli xabiso limiselwe umthombo wokukhanya okanye i-luminaire iyonke okanye ii-LED ezisetyenziswa kuyo.Ii-LED ngokwazo zinexabiso eliphezulu.Kuhlala kukho ilahleko ekusebenzeni kakuhle, umzekelo xa abaqhubi kunye ne-optics zisetyenziswa.Esi sizathu sokuba ii-LED zinokuba nemveliso ye-180lm/W, ngelixa imveliso ye-luminaire iyonke yi-140lm/W.Abavelisi kufuneka bachaze ixabiso lomthombo wokukhanya okanye i-luminaire.Imveliso ye-luminaire ibaluleke ngaphezu komthombo wokukhanya, kuba izibane ze-LED zivavanywa xa zizonke.
Into yamandla ibonisa ubudlelwane phakathi kokufakwa kwamandla kunye namandla asetyenziselwa ukwenza i-LED isebenze.Kusekho ilahleko kwiitshiphusi ze-LED kunye nabaqhubi.Ngokomzekelo, isibane se-LED se-100W sinePF ye-0.95.Kule meko, umqhubi ufuna i-5W ukuba isebenze, oko kuthetha ukuba i-95W amandla e-LED kunye namandla omqhubi we-5W.
I-UGR imele ukuKhathaza okuManyeneyo, okanye ixabiso lomtha lomthombo wokukhanya.Eli lixabiso elibaliweyo kwiqondo lokuphola kwe-luminaire kwaye lixabisekile ekuhloleni induduzo.
I-CRI okanye i-Color Rendering Index isalathiso sokumisela indlela imibala yendalo eboniswa ngayo ngokukhanya kwesibane, kunye nexabiso lokubhekisela kwi-halogen okanye isibane se-incandescent.
I-Standard Deviation Color Matching (SDMC) yiyunithi yokulinganisa umahluko wombala phakathi kweemveliso ezahlukeneyo ekukhanyeni.Ukunyamezela kombala kubonakaliswa ngamanyathelo ahlukeneyo eMac-Adam.
I-DALI imele iDigital Addressable Lighting Interface kwaye isetyenziswa kulawulo lokukhanya.Kuthungelwano okanye isisombululo esizimeleyo, i-fitting nganye yabelwe idilesi yayo.Oku kuvumela isibane ngasinye ukuba sifikeleleke kwaye silawulwe (kwi-off - dimming).I-DALI iqulethe i-2-wire drive ehamba ngaphandle konikezelo lwamandla kwaye inokwandiswa ngentshukumo kunye nezinzwa zokukhanya phakathi kwezinye izinto.
Umgangatho we-LB ukhankanywa ngakumbi kwiinkcukacha zesibane.Oku kunika isibonakaliso esihle somgangatho, zombini ngokubhekiselele ekubuyiseleni ukukhanya kunye nokungaphumeleli kwe-LED.Ixabiso 'L' libonisa ubungakanani bokukhanya kwakhona emva kobomi bonke.I-L70 emva kweeyure zokusebenza ze-30,000 ibonisa ukuba emva kweeyure zokusebenza ze-30,000, i-70% yokukhanya ihlala.I-L90 emva kweeyure ze-50,000 ibonisa ukuba emva kweeyure zokusebenza ze-50,000, i-90% yokukhanya ishiywe, ngaloo ndlela ibonisa umgangatho ophezulu kakhulu.Ixabiso 'B' likwabalulekile.Oku kunxulumene nepesenti enokuthi itenxe kwixabiso lika-L.Oku kusenokuba ngenxa yokusilela kwee-LEDs.I-L70B50 emva kweeyure ze-30,000 yinkcazo eqhelekileyo kakhulu.Kubonisa ukuba emva kweeyure zokusebenza ze-30,000, i-70% yexabiso elitsha lokukhanya lishiywe, kwaye ubuninzi be-50% buphambuka kule nto.Ixabiso le-B lisekelwe kwimeko embi kakhulu.Ukuba ixabiso le-B alikhankanywanga, i-B50 iyasetyenziswa.I-PVTECH luminaires ilinganiswe nge-L85B10, ebonisa umgangatho ophezulu wezibane zethu.
Ii-motion detectors okanye izinzwa zobukho yindibaniselwano egqwesileyo yokusetyenziswa kunye nezibane ze-LED, kuba zinokuvula nokucima ngokuthe ngqo.Olu hlobo lokukhanyisa lufanelekile kwiholo, okanye kwindlu yangasese, kodwa lunokusetyenziswa kwiindawo ezahlukeneyo zoshishino kunye neendawo zokugcina abantu abasebenza kuzo.Uninzi lwezibane ze-LED zivavanywa ukuba ziphile ngamaxesha angama-1,000,000 okutshintsha, okulungileyo iminyaka yokusetyenziswa.Ingcebiso enye: kukhethwa ukuba kufakwe umtshina oshukumayo owahlukileyo kwi-luminaire, kuba umthombo wokukhanya unokuhlala ixesha elide kune-sensor.Ngaphezu koko, inzwa ephosakeleyo inokuthintela ukonga iindleko ezongezelelweyo.
Ubushushu bokusebenza bunempembelelo enkulu kubomi be-LEDs.Ukushisa okucetyiswayo okusebenzayo kuxhomekeke ekupholiseni okukhethiweyo, umqhubi, ii-LED kunye nezindlu.Iyunithi kufuneka igwetywe xa iyonke, kunokuba kugwetywe amacandelo ayo ngokwahlukeneyo.Ngapha koko, 'elona khonkco libuthathaka' linokuba sisilawuli.Iindawo zobushushu obuphantsi zilungele ii-LEDs.Ukupholisa kunye nokukhenkceza iiseli zifanelekile ngokukodwa, kuba ii-LED zinokususa ubushushu kakuhle.Kuba ubushushu obuncinci sele benziwe nge-LED kunokukhanya okuqhelekileyo, ukupholisa kuya kufuna amandla amancinci ukugcina ubushushu bakho.Imeko yokuphumelela!Kwiindawo ezifudumeleyo, imeko iyahluka.Uninzi lwezibane ze-LED zineqondo lokushisa eliphezulu lokusebenzisa i-35 ° Celsius, ukukhanya kwe-PVTECH kuya ku-65 ° C!
Ii-LEDs zinezibane ezigxininisiweyo zokukhanya, ngokungafaniyo nezibane zendabuko ezisasaza ukukhanya kwiindawo ezizungezile.Xa izibane ze-LED zibonelelwa ngezibonisi, ukukhanya okuninzi okusembindini we-beam kushiya inkqubo ngaphandle kokudibana nesibonisi.Oku kunciphisa iqondo lokumodareyitha kwesibane sokukhanya kwaye kunokuba ngunobangela wokumfamekisa.Iilensi zinceda ukukhokela phantse nawuphi na umtha wokukhanya okhutshwa yi-LED.
