Ukwahlulela ukuthi iUkukhanya kwe-LEDumthombo yilokho esikudingayo, ngokuvamile sisebenzisa i-sphere ehlanganisayo ukuze sihlole, bese sihlaziya idatha yokuhlola.Indilinga evamile yokuhlanganisa inganikeza amapharamitha ayisithupha abalulekile alandelayo: ukuguquguquka okukhanyayo, ukusebenza kahle okukhanyayo, i-voltage, ukudidiyelwa kombala, izinga lokushisa lombala, kanye nenkomba yokunikeza umbala (Ra).(Empeleni, kunamanye amapharamitha amaningi, afana nobude beza obuphakeme, ubude beza beza obubusayo, amandla amnyama, i-CRI, njll.) Namuhla, ake sixoxe ngokubaluleka kwala mapharamitha ayisithupha emithonjeni yokukhanya kanye nemiphumela yawo efanayo.

Ukuguquguquka okukhanyayo: I-flux ekhanyayo ibhekisela emandleni emisebe angazwakala ngeso lomuntu, okungukuthi, amandla emisebe ephelele akhishwa yi-LED, kumalumens (lm).I-flux ekhanyayo iyisilinganiso esiqondile kanye nenani elibonakalayo elibonakalayo lokwahlulela ukukhanya kwe-LED.

Amandla kagesi:I-voltage ingumehluko ongaba khona phakathi kwezigxobo ezinhle nezimbi ze-Isibani se-LEDubuhlalu, okuyisilinganiso esiqondile, ngamavolthi (V).Ihlobene ne-voltage ye-chip esetshenziswa yi-LED.

Ukusebenza kahle okukhanyayo:ukusebenza kahle okukhanyayo, okungukuthi, isilinganiso sakho konke ukugeleza okukhanyayo okukhishwa umthombo wokukhanya kumandla okufaka esewonke, inani elibaliwe, ku-lm/W.Ku-LED, amandla kagesi okufakwayo asetshenziselwa ukukhanyisa nokushisa.Ukusebenza kahle okuphezulu kokukhanya kubonisa ukuthi kunezingxenye ezimbalwa ezisetshenziselwa ukushisa, okubuye kube ukubonakaliswa kokukhipha kahle ukushisa.

Kulula ukubona ubudlelwano phakathi kwalaba abathathu abangenhla.Lapho okwamanje kunqunywa, ukusebenza kahle okukhanyayo kwe-LED empeleni kunqunywa ukuguquguquka okukhanyayo kanye ne-voltage.I-flux ekhanyayo ephezulukanye ne-voltage ephansi iholela ekusebenzeni kahle kokukhanya okuphezulu.Ngokuqondene ne-chip yamanje enkulu eluhlaza okwesibhakabhaka embozwe nge-fluorescence eluhlaza okuphuzi, ngenxa yokuthi i-voltage eyodwa eyinhloko ye-chip eluhlaza okwesibhakabhaka ngokuvamile imayelana ne-3V, okuyinani elizinzile, ukuthuthukisa ukusebenza kahle kokukhanya kuncike ikakhulukazi ekwandiseni ukuguquguquka okukhanyayo.

Ukudidiyela umbala:ukudidiyela kombala, okungukuthi, indawo yombala kumdwebo we-chromaticity, inani lokulinganisa.Kuhlelo oluvamile olusetshenziswayo lwe-CIE1931 lombala, izixhumanisi zimelelwa amanani ka-x kanye no-y.Inani lika-x lingabhekwa njengezinga lokukhanya okubomvu ku-spectrum, futhi inani lika-y libhekwa njengezinga lokukhanya okuluhlaza.

Izinga lokushisa lombala:inani elibonakalayo elikala umbala wokukhanya.Lapho imisebe yomzimba omnyama ngokuphelele ifana ncamashi nemisebe yomthombo wokukhanya endaweni ebonakalayo, izinga lokushisa lomzimba omnyama libizwa ngokuthi izinga lokushisa lombala lomthombo wokukhanya.Izinga lokushisa lombala liyinani lokulinganisa, kodwa lingabalwa ngezixhumanisi zemibala ngesikhathi esifanayo.

Inkomba yokunikeza umbala (Ra):esetshenziselwa ukuchaza ikhono lokubuyisela lomthombo wokukhanya kumbala wento.Kunqunywa ngokuqhathanisa umbala wokubukeka wezinto ngaphansi komthombo wokukhanya ojwayelekile.Inkomba yethu yokunikeza umbala empeleni iyisilinganiso sezilinganiso zemibala ekhanyayo eyisishiyagalombili ebalwa nge-sphere ehlanganisayo ngokumpunga okukhanyayo, okumpunga okuphuzi okumnyama, okuluhlaza okuphuzi okugcwele, okuluhlaza okuphuzi okumaphakathi, okuluhlaza okwesibhakabhaka okukhanyayo, okuluhlaza okwesibhakabhaka ngokukhanyayo, okuluhlaza okwesibhakabhaka ngokukhanyayo, nokunsomi ngokubomvu. .Kungatholakala ukuthi akubandakanyi okubomvu okugcwele, okuvame ukwaziwa ngokuthi u-R9.Ngenxa yokuthi okunye ukukhanyisa kudinga ukukhanya okubomvu okwengeziwe (njengokukhanya kwenyama), i-R9 ivame ukusetshenziswa njengepharamitha ebalulekile yokuhlola i-LED.

Izinga lokushisa lombala lingabalwa ngezixhumanisi zombala.Kodwa-ke, uma ubheka ngokucophelela umdwebo we-chromaticity, uzothola ukuthi izinga lokushisa lombala elifanayo lingahambisana nezixhumanisi eziningi zemibala, kuyilapho izixhumanisi zombala zihambisana kuphela nezinga lokushisa lombala owodwa.Ngakho-ke, kunembe kakhulu ukusebenzisa izixhumanisi zemibala ukuchaza umbala womthombo wokukhanya.Inkomba yesibonisi ngokwayo ayihlangene nakancane nenhlanganisela yombala nezinga lokushisa lombala, kodwa uma izinga lokushisa liphezulu, umbala wokukhanya ubanda, izingxenye ezibomvu kancane emthonjeni wokukhanya, futhi kunzima ukuzuza inkomba yesibonisi ephezulu kakhulu.Ngemithombo yokukhanya efudumele enezinga lokushisa eliphansi lombala, kunezingxenye ezibomvu ezengeziwe, ukumbozwa kwe-spectrum ebanzi, futhi eduze ne-spectrum yokukhanya kwemvelo, ukuze inkomba yokunikeza umbala ibe phezulu ngokwemvelo.Yingakho ama-LED angaphezu kuka-95Ra emakethe enezinga lokushisa eliphansi lombala.
