Ukwahlulela ukuthi iUkukhanya kwe-LEDumthombo yilokho esikudingayo, ngokuvamile sisebenzisa i-sphere ehlanganisayo ukuze sihlole, bese sihlaziya ngokuya ngedatha yokuhlola. I-sphere evamile yokuhlanganisa inganikeza amapharamitha ayisithupha abalulekile alandelayo: ukuguquguquka okukhanyayo, ukusebenza kahle okukhanyayo, i-voltage, ukudidiyelwa kombala, izinga lokushisa lombala kanye nenkomba yokunikeza umbala (RA). (eqinisweni, kuneminye imingcele eminingi, njenge-wavelength ephezulu, i-wavelength eyinhloko, amandla amnyama, i-CRI, njll.) namuhla sizoxoxa ngokubaluleka kwala mapharamitha ayisithupha emthonjeni wokukhanya kanye nomthelela wawo ofanayo.

I-flux ekhanyayo: i-flux ekhanyayo ibhekisela emandleni emisebe angazwakala ngamehlo omuntu, okungukuthi, amandla emisebe ephelele akhishwa yi-LED, iyunithi: i-lumen (LM). I-Luminous flux iyinani lokulinganisa eliqondile kanye nenani elibonakalayo elibonakalayo ukwahlulelaukukhanya kwe-LED.

I-Voltage: I-voltage ingumehluko ongaba khona phakathi kwama-electrode amahle namabiUbuhlalu besibani se-LED, okuyisilinganiso esiqondile, iyunithi: ama-volts (V). Okuhlobene nezinga le-voltage ye-chip esetshenziswa yi-LED.

Ukusebenza kahle okukhanyayo: ukusebenza kahle okukhanyayo, okungukuthi isilinganiso sengqikithi yokuguquguquka okukhanyayo okukhishwa umthombo wokukhanya kokokufaka kwamandla, inani elibaliwe, iyunithi: LM / W. Kuma-LED, amandla okufaka asetshenziselwa ikakhulukazi ukukhipha ukukhanya nokushisa. isizukulwane. Uma ukusebenza kahle kokukhanya kuphezulu, kusho ukuthi kunezingxenye ezimbalwa ezisetshenziselwa ukukhiqiza ukushisa, okubuye kube ukubonakaliswa kokushisa okuhle kokushisa.

Akunzima ukubona ubudlelwano phakathi kwalezi zincazelo ezintathu ezingenhla. Lapho ukusetshenziswa kwamanje kunqunywa, ukusebenza kahle kokukhanya kwe-LED empeleni kunqunywa ukuguquguquka okukhanyayo kanye ne-voltage. Uma i-flux ekhanyayo iphezulu futhi i-voltage iphansi, ukusebenza kahle kokukhanya kuphezulu. Ngokuqondene nechip yamanje enkulu eluhlaza okwesibhakabhaka embozwe nge-fluorescence eluhlaza okuphuzi, njengoba i-voltage eyodwa eyinhloko ye-chip eluhlaza okwesibhakabhaka ngokuvamile iba ngu-3V, okuyinani elizinzile, ukuthuthukiswa kokusebenza kahle kokukhanya kuncike ikakhulukazi ekuthuthukisweni kokuguquguquka okukhanyayo.

Ukudidiyela umbala: inhlanganisela yombala, okungukuthi, indawo yombala kumdwebo we-chromaticity, okuyinani lokulinganisa. Kuhlelo oluvamile olusetshenziswayo lwe-CIE1931 lombala, izixhumanisi zimelelwa amanani angu-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 ye-blackbody ephelele kanye nemisebe yomthombo wokukhanya endaweni ebonakalayo kufana, izinga lokushisa lomzimba omnyama libizwa ngokuthi izinga lokushisa lombala womthombo wokukhanya. Izinga lokushisa lombala liyinani elilinganiselwe, kodwa lingabalwa ngezixhumanisi zemibala.

Inkomba yokunikeza umbala (i-RA): isetshenziselwa ukuchaza ikhono lomthombo wokukhanya lokubuyisela umbala wento. Kunqunywa ngokuqhathanisa umbala wokubukeka wento ngaphansi komthombo wokukhanya ojwayelekile. Inkomba yethu yokunikeza umbala empeleni iyinani elimaphakathi elibalwa nge-sphere ehlanganisayo yezilinganiso zemibala ekhanyayo eyisishiyagalombili yokumpunga ngokukhanyayo, okumpunga okuphuzi, okuluhlaza okugcwele okuphuzi, okuluhlaza okuphuzi okumaphakathi, okuluhlaza okwesibhakabhaka okukhanyayo, okuluhlaza okwesibhakabhaka okukhanyayo, okuluhlaza okwesibhakabhaka ngokukhanyayo nokubomvu ngokukhanyayo. onsomi. Kungatholakala ukuthi ayifaki okubomvu okugcwele, okungukuthi, u-R9. Njengoba okunye ukukhanyisa kudinga ukukhanya okubomvu okwengeziwe (njengokukhanya kwenyama), i-R9 ivame ukusetshenziswa njengepharamitha ebalulekile yokuhlola ama-LED.

Izinga lokushisa lombala lingabalwa ngezixhumanisi zombala, kodwa uma uqaphela ngokucophelela ishadi le-chromaticity, uzothola ukuthi izinga lokushisa lombala elifanayo lingahambisana namapheya amaningi ezixhumanisi zemibala, kuyilapho ipheya yezixhumanisi zombala ihambisana 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-ke, uma izinga lokushisa lombala liphezulu nombala okhanyayo upholile, ingxenye ebomvu emthonjeni wokukhanya iyancipha, futhi inkomba yokubonisa kunzima ukuba phezulu kakhulu. Ngomthombo wokukhanya ofudumele onezinga lokushisa eliphansi lombala, ingxenye ebomvu ingaphezulu, ukumbozwa kwe-spectrum kubanzi, futhi i-spectrum iseduze nokukhanya kwemvelo, inkomba yombala ingaba phezulu ngokwemvelo. Lesi futhi isizathu esenza ukuthi ama-LED angaphezu kuka-95ra emakethe abe nokushisa okuphansi kombala.
