Bonke oogqirha baye bema phantsi kokukhanya okwenza izicubu zibukeke zingalunganga. Ayingombala umnyama nje kuphela — umbala ongalunganga. Amathumbu afanele ukuba apinki abukeka engwevu, kwaye igazi eliphuma kwimithambo yegazi kuba nzima ukuwahlula kwimithambo yegazi. Isizathu asisoloko sibukhali. Ihlala ingomnye wamanani amabini kwiphepha ledatha: isalathisi sokwenziwa kombala (CRI) kunye nobushushu bombala. Ukuqonda ezi parameter zimbini ngumahluko phakathi kokuthenga ukukhanya okubonisa ifoto yencwadana kunye nokuthenga okubonisa izicubu ngendlela eziyiyo ngokwenene.
Oko iCRI iyilinganisayo ngokwenene
I-CRI, edla ngokubhalwa njengoRa, sisikali esiphakathi kwe-0–100 esithelekisa indlela ngokuchanekileyo umthombo wokukhanya ovelisa ngayo imibala ngokuchasene nesalathiso — ukukhanya kwelanga kwendalo okanye i-radiator yomzimba omnyama — efumana amanqaku ayi-100. Ayinanto yakwenza nokukhanya. Ukukhanya kunokuba bukhali kodwa kungabonakali imibala kakuhle.
Isalathisi silinganisa ukuthembeka kwimibala esibhozo yovavanyo oluqhelekileyo lwe-pastel. Iinguqulelo ezongeziweyo zongeza iisampulu ezigcweleyo, kwaye eyona ibaluleke kakhulu kutyando yi-R9, ebomvu nzulu. Igazi, izihlunu kunye ne-mucosa zigcwele ubomvu obufanayo nobo be-LED yokuqala. Isixhobo singafumana i-Ra 95 kodwa sifumane amanqaku abuthathaka kwi-R9, ngoko ke inombolo yesihloko ifanelekile ukuyifunda ngeliso elinye kumbhalo omncinci.
Kutheni i-CRI ephezulu ibalulekile kwigumbi lokuSebenza
Izigqibo zotyando zenziwa ngokwahluka kombala okuncinci. Ukwahlula ukuphuma kwegazi kwimithambo yegazi, ukuchonga umda wezicubu ezifileyo kunye nokuvavanya ukuvuza kwegazi konke kuxhomekeke ekuboneni umbala obomvu wokwenene. Ukubonakala kakubi kuyawususa loo mahluko. Okubonakala “kumnyama kancinci” phantsi kokukhanya okuphantsi kwe-CRI kudla ngokuba ngumbala obomvu owahlukileyo ngokupheleleyo.
Uninzi loogqirha botyando lukhumbula imeko ethile. Amathumbu ayebonakala edakumbile, iqela alizange livumelane ngokuba yayiyi-ischemia okanye sisibane nje, kwaye ukuphinda ubeke intloko akwenzanga nto - kuba ingxaki yayingeyiyo i-engile kodwa yi-spectrum. Tshintsha umthombo wokukhanya kwaye izicubu ezifanayo zifundeka ngokwahlukileyo. Olo luvavanyo lokwenyani lokukhanya kotyando.
Imigangatho iyithatha nzulu le nto. I-IEC 60601-2-41, umgangatho wokhuseleko kunye nokusebenza kwezibane zotyando, imisela ubuncinci be-CRI ye-Ra 85, kwaye isikhokelo seklinikhi ngokubanzi sicebisa i-Ra 90 okanye ngaphezulu ukuze kwahlulwe izicubu ngendlela ethembekileyo.Izibane zotyando ze-LEDrhoqo uhambisa iRa 95 okanye ngaphezulu. Xa umthengisi ebiza iCRI ephezulu, cela nexabiso le-R9 - kulapho kuhlala khona iireds.
Ubushushu boMbala kunye nendlela iLiso eliFunda ngayo iTishu
Ubushushu bombala, ngokobuchwephesha obuhambelanayo nobushushu bombala (CCT), buchaza indlela ukukhanya okumhlophe okubonakala ngayo. Malunga ne-3,000–3,800K ibukeka ifudumele kwaye ityheli; kufutshane ne-5,000 K isondela emini yendalo; ngaphezulu kwe-5,400 K ijika ibe luhlaza okwesibhakabhaka. Izibane zotyando zingaphakathi kwe-3,000–6,700K evumelekileyo ngumgangatho, kwaye uninzi lwezinto ezisetyenziswa kwigumbi lokutya zisebenza kwi-4,000–5,000 K.
Olu khetho alunabuhle. Ukukhanya okufudumeleyo okukufutshane ne-3,800K kuyathambile kwizicubu ezibomvu kwaye kuyaphumla xa zinde, kodwa kunokugquma i-cyanosis encinci. Ukukhanya okufana nokukhanya kwelanga kwi-4,500–5,000K kulola umahluko phakathi kwezakhiwo ezincinci kunye neentlobo zezicubu - zibalulekile xa usebenza nzulu kwindawo apho umahluko kuphela onakho. Ezinye izixhobo zanamhlanje zibonelela ngobushushu bombala obuhlengahlengiswayo, zivumela iqela ukuba litshintshe iindlela ngaphandle kokutshintsha intloko yokukhanya.
I-CRI kunye nobushushu bombala azifani
Le yeyona ngxaki ixhaphakileyo kwi-OR corridor. I-CRI ikuxelela indlela imibala evezwa ngayo ngokuthembeka; ubushushu bombala bukuxelela ukuba ukukhanya kubonakala kufudumele okanye kupholile kangakanani. Zii-axes ezizimeleyo. Ibhalbhu ye-halogen iveza umbala kakuhle kakhulu - ngumthombo womzimba omnyama ngokwendlela eyilwe ngayo - kodwa ihlala kwi-3,200K ephuzi ephantsi. Ii-LED zakuqala zazisingatha kakuhle ubushushu bombala kodwa ekuqaleni zazisokola ukupeyinta, ingakumbi obomvu obunzulu. Izibane ezibini zinokubelana ngobushushu bombala kwaye zisahluka ngokubonakalayo kumbala, ngoko ke inani elinye lodwa likuxelela okuncinci kakhulu.
Yintoni Omele Uyihlole Ngaphambi Kokuba Ukhethe
Funda iphepha ledatha njengogqirha, kungekhona umthengi. Jonga i-CRI Ra kuqala — ngumlinganiselo wesihloko sombala — uze emva koko ube yi-R9, uze emva koko ube nobushushu bombala, uze uphathe ukukhanya njengombuzo owahlukileyo. Zama ukukhanya okukwindawo ukuba unako — beka isandla esineglavu phantsi kwaso uze ufunde imibala yesikhumba. Qinisekisa ukuba isixhobo siqinisekisiwe yi-IEC 60601-2-41 ngaphambi kokuba sifike kwi-OR yakho.
Imigaqo efanayo iyasebenza nakwiindawo ezimfutshane.Izibane zezibane ze-LED zotyandokwaye ii-loupes zisebenza kumgama omiselweyo wokusebenza, apho ukukhanya kufuneka kube yinyani njengesibane sesilingi - kwaye rhoqo, kuba intsimi incinci kwaye yonke inguqu yombala iyandiswa. Kwisibane sentloko, i-CRI kunye nobushushu bombala zibalulekile njengephethini yemitha.
Apha eMicare, sichaza izibane zethu zezibane ze-LED kunye nee-loupes ezijikeleze la manani mabini endaweni yokujonga ukukhanya kuphela, kwaye sabelana ngedatha epheleleyo ye-photometric - i-CRI, i-R9 kunye nobushushu bombala - ngaphambi kokuba uzame iyunithi. Xa ukukhanya kubonakalisa izicubu ngokunyaniseka, lonke iqela lisebenza ngcono. Elo liphepha leenkcukacha ekufuneka lingashiywa ngugqirha.
