Wonke udokotela ohlinzayo uke wema ngaphansi kokukhanya okwenza izicubu zibukeke zingalungile. Hhayi nje ukuthi zimnyama - umbala awulungile. Ithumbu okufanele libe bomvu libukeka limpunga, futhi igazi elisemithanjeni liba nzima ukulibona lisuka emithanjeni. Imbangela ayivamile ukuba namandla. Ngokuvamile liyinombolo eyodwa kwezimbili eziku-datasheet: inkomba yokunikeza umbala (i-CRI) kanye nokushisa kombala. Ukuqonda la mapharamitha amabili umehluko phakathi kokuthenga ukukhanya okuhlobisa isithombe sencwajana nokuthenga okubonisa izicubu ngendlela eziyiyo ngempela.
Lokho i-CRI Ekulinganisa Ngempela
I-CRI, evame ukubhalwa ngokuthi i-Ra, iyisikali esingu-0–100 esiqhathanisa ukuthi umthombo wokukhanya uveza kanjani imibala ngokunembile uma kuqhathaniswa nereferensi — ukukhanya kwelanga kwemvelo noma i-radiator enomzimba omnyama — ethola amaphuzu angu-100. Ayinalutho oluphathelene nokukhanya. Ukukhanya kungaba namandla kakhulu kodwa kuqhubeke kwenze imibala ibe mibi.
Inkomba ilinganisa ukuthembeka kwemibala eyisishiyagalombili ejwayelekile yokuhlolwa kwe-pastel. Izinhlobo ezinwetshiwe zengeza amasampula agcwele, kanti ebaluleke kakhulu ekuhlinzeni yi-R9, ebomvu ngokujulile. Igazi, imisipha kanye ne-mucosa kugcwele okubomvu okufana kakhulu nemiklamo ye-LED yokuqala. I-fixture ingathola i-Ra 95 kodwa ithole amaphuzu amancane ku-R9, ngakho-ke inombolo yesihloko ifanele ukufundwa ngeso elilodwa ephepheni elincane.
Kungani I-CRI Ephakeme Ibalulekile Egumbini Lokuhlinzwa
Izinqumo zokuhlinzwa zenziwa ngokwehluka kombala okuncane. Ukuhlukanisa ukuphuma kwegazi emithanjeni yegazi, ukuhlonza umkhawulo wezicubu ezifile kanye nokuhlola ukukhishwa kwegazi konke kuncike ekuboneni ubomvu bangempela. Ukubukeka okungekuhle kususa lawo mahluko. Okubukeka “kumnyama kancane” ngaphansi kokukhanya okuphansi kwe-CRI kuvame ukuba nombala obomvu ohlukile ngokuphelele.
Odokotela abaningi abahlinzayo bakhumbula icala elithile. Amathumbu ayebukeka edangele, ithimba alikwazanga ukuvumelana ngokuthi ngabe kwakuyi-ischemia noma isibani nje, futhi ukubeka kabusha ikhanda akwenzanga lutho - ngoba inkinga kwakungeyona i-engeli kodwa i-spectrum. Shintsha umthombo wokukhanya bese izicubu ezifanayo zifundeka ngendlela ehlukile. Lokho ukuhlolwa kwangempela kokukhanya kokuhlinzwa.
Izindinganiso zithatha lokhu ngokungathi sína. I-IEC 60601-2-41, indinganiso yokuphepha nokusebenza kwama-luminaires okuhlinzwa, ibeka i-CRI encane ye-Ra 85, futhi isiqondiso sezokwelapha ngokuvamile sincoma i-Ra 90 noma ngaphezulu ukuze kuhlukaniswe izicubu ngendlela ethembekile.Izibani zokuhlinzwa ze-LEDnjalo uletha u-Ra 95 noma ngaphezulu. Uma umhlinzeki ebiza i-CRI ephezulu, cela nenani lika-R9 — yilapho okubomvu kuhlala khona.
Izinga Lokushisa Lombala kanye Nendlela Iso Elifunda Ngayo Izicubu
Izinga lokushisa lombala, ngokomthetho elibizwa ngokuthi izinga lokushisa lombala elihlobene (i-CCT), lichaza ukuthi ukukhanya kuvela kanjani okumhlophe. Cishe ama-3,000–3,800K abukeka efudumele futhi ephuzi; cishe ama-5,000 K asondela emini yemvelo; ngaphezu kwama-5,400 K aphenduka abe luhlaza okwesibhakabhaka. Izibani zokuhlinza zihlala ngaphakathi kwebhendi engu-3,000–6,700K evunyelwe yijwayelekile, futhi izinto eziningi ezisetshenziswa egumbini lokuhlinza zisebenza kuma-4,000–5,000 K.
Ukukhetha akulona ubuhle. Ukukhanya okufudumele okuseduze no-3,800K kuthambile ezicutshini ezibomvu futhi kuyaphumula ezimweni ezinde, kodwa kungafihla i-cyanosis encane. Ukukhanya okufana nokukhanya kwasemini ku-4,500–5,000K kulola umehluko phakathi kwezakhiwo ezincane nezinhlobo zezicubu - kuyasiza uma usebenza ngokujulile emgodini lapho ukungafani kuphela onakho. Ezinye izinto zesimanje zinikeza izinga lokushisa lombala elilungisekayo, okuvumela iqembu ukuthi lishintshe izindlela ngaphandle kokushintsha ikhanda lokukhanya.
I-CRI kanye Nokushisa Kombala Akuyona Into Efanayo
Lokhu ukudideka okuvame kakhulu emzileni we-OR. I-CRI ikutshela ukuthi imibala ihunyushwa kanjani ngokwethembeka; izinga lokushisa lombala likutshela ukuthi ukukhanya kuvela kufudumele noma kupholile kangakanani. Ziyi-axes ezimele. Ibhalbhu ye-halogen iveza umbala kahle kakhulu - ingumthombo womzimba omnyama ngomklamo - kodwa ihlala ku-3,200K ephansi, ephuzi. Ama-LED okuqala aphatha kahle izinga lokushisa lombala kodwa ekuqaleni ayenenkinga yokuveza, ikakhulukazi obomvu obujulile. Izibani ezimbili zingabelana ngezinga lokushisa lombala futhi zisahluka ngokubonakalayo ngokuthembeka kombala, ngakho inombolo eyodwa iyodwa ikutshela okuncane kakhulu.
Okufanele Uhlole Ngaphambi Kokukhetha
Funda ishidi ledatha njengodokotela, hhayi umthengi. Bheka i-CRI Ra kuqala — iyisikali esiyinhloko sokuguqulwa kombala — bese kuba yi-R9, bese kuba izinga lokushisa lombala, bese uphatha ukukhanya njengombuzo ohlukile. Zama ukukhanya okukhona uma ungakwazi — faka isandla esinamagilavu ngaphansi kwaso bese ufunda imibala yesikhumba. Qinisekisa ukuthi i-factory iqinisekiswe yi-IEC 60601-2-41 ngaphambi kokuba ifike ku-OR yakho.
Izimiso ezifanayo ziyasebenza emabangeni amafushane.Izibani zokukhanyisa ze-LEDfuthi ama-loupe asebenza ngaphakathi kwebanga eliqondile lokusebenza, lapho ukukhanya kufanele kube qotho njengesibani sophahla — futhi ngokuvamile kakhulu, ngoba insimu incane futhi yonke inguquko yombala iyakhuliswa. Ngesibani sekhanda, i-CRI kanye nokushisa kombala kubaluleke kakhulu njengephethini ye-beam.
KwaMicare, sichaza izibani zethu zokukhanyisa ze-LED kanye nama-loupe azungeze lezi zinombolo ezimbili kunokuba sizungeze ukukhanya kuphela, futhi sabelana ngedatha ephelele ye-photometric - i-CRI, i-R9 kanye nokushisa kombala - ngaphambi kokuthi uzame iyunithi. Uma ukukhanya kuveza izicubu ngokwethembeka, lonke ithimba lisebenza kangcono. Lelo yiphepha lemininingwane okungekho udokotela okufanele alidlule.
