Ukuchaneka kokukhanya kubaluleke kakhulu kwiindawo zokuhlala, zorhwebo kunye nezoshishino namhlanje. Oku kulinganiswa kwaye kulinganiswe ngokusebenzisa i-Color Rendering Index (CRI), esemgangathweni yoshishino lokulinganisa ukuchaneka kokukhanya okuthile. I-CRI ibaleka kwisikali ukuya kwi-100, eyi-CRI yesibane sokukhanya kwerediyetha yomzimba omnyama. Oku kukhanya kwereferensi mhlawumbi luhlobo lwe-incandescent yokukhanya okwenziweyo okanye ukukhanya kwelanga kwendalo, eyona mithombo yokukhanya echanekileyo ekhoyo. Kuyafaneleka ukuba uqaphele ukuba i-CRI izimele kwi-Correlated Color Temperature (CCT), igama elisetyenziswa rhoqo kunye ne-CRI xa lichaza iimpawu zokukhanya. I-CCT ilinganisa umbala wangempela wokukhanya oveliswe eKelvins kwaye ayinanto yakwenza nokuchaneka kokukhanya kokukhanya.

Yintoni iSalathiso sokuBonelela ngoMbala (CRI)?

Isalathiso sombala wonikezelo (CRI) ngumlinganiselo wobungakanani bokukwazi komthombo wokukhanya ukutyhila imibala yezinto ezahlukeneyo ngokuthembekileyo xa kuthelekiswa nomthombo wokukhanya wendalo okanye oqhelekileyo. Imithombo yokukhanya ene-CRI ephezulu iyanqweneleka kwizicelo ezibaluleke kakhulu zombala ezifana nokunakekelwa kwe-neonatal kunye nokubuyiselwa kobugcisa. Ichazwa yiKhomishini yaMazwe ngaMazwe yoKhanyiso (CIE) ngolu hlobo lulandelayo:

Unikezelo lombala: Isiphumo sesikhanyiso kwinkangeleko yombala wezinto ngokuqonda okanye uthelekiso lwengqondo kunye nenkangeleko yombala phantsi kwesalathiso okanye isikhanyiso esiqhelekileyo.

I-CRI yomthombo wokukhanya ayibonisi umbala obonakalayo womthombo wokukhanya; olo lwazi lunikwa bubushushu bombala obunxibeleleneyo (CCT). I-CRI imiselwa ngumthombo wokukhanya isikram. Isibane se-incandescent sine-spectrum eqhubekayo; isibane se-fluorescent sinomgca we-discrete spectrum, oku kuthetha ukuba isibane se-incandescent sine-CRI ephezulu.

Ixabiso elidla ngokucatshulwa njenge "CRI" kwiimveliso zokukhanyisa ezifumanekayo kurhwebo ngokufanelekileyo libizwa ngokuba yi-CIE Ra value, "i-CRI" ibe ligama eliqhelekileyo kunye ne-CIE Ra ibe yi-international standard color rendering index.

Ngokwenani, elona xabiso liphezulu le-CIE Ra li-100 kwaye liya kunikwa kuphela umthombo onobubanzi obufana nokukhanya kwemini, kufutshane kakhulu nomzimba omnyama (izibane ze-incandescent ziyimizimba emnyama ngokusebenzayo), ziwela kumaxabiso angalunganga eminye imithombo yokukhanya. Ukukhanya okuphantsi kwe-sodium ene-low-pressure ine-CRI embi; Izibane ze-fluorescent zivela malunga ne-50 kwiintlobo ezisisiseko, ukuya kuthi ga kwi-98 yolona hlobo lwe-multi-phosphor. Ii-LED eziqhelekileyo ezinombala omhlophe zine-CRI ye-80, i-90, okanye ngaphezulu.

Ukuhanjiswa kwamandla eSpectral

Indawo ebonakalayo yombane we-electromagnetic spectrum yenziwe yimitha yemitha enobude bamaza ukusuka malunga nama-400 ukuya kuma-750 nanometers. Inxalenye eluhlaza okwesibhakabhaka ye-spectrum ebonakalayo yi-wavelength emfutshane, kwaye inxalenye ebomvu yi-wavelength ende kunye nayo yonke imilinganiselo yombala phakathi.

Iigrafu zonikezelo lwamandla eSpectral zibonisa amandla azalanayo obude bobude obungaphaya kobubanzi obubonakalayo bomthombo wokukhanya onikiweyo. Ezi grafu zikwaveza amandla omthombo wokukhanya ukunika yonke okanye imibala ekhethiweyo.

Ngezantsi jonga indlela eqhelekileyo yegrafu yokuhambisa amandla okubonwa emini.

Qaphela ubukho obuqinileyo (amandla anxulumeneyo aphezulu) BONKE ubude bamaza (okanye “imibala egcweleyo yombala”). Ukukhanya kwemini kubonelela ngelona nqanaba liphezulu lombala wonikezelo kwi-spectrum.

Thelekisa ukukhanya kwemini kunye nesibane se-LED.

Owona mahluko ucacileyo linqanaba elisezantsi jikelele lamandla anxulumeneyo xa kuthelekiswa nokukhanya kwemini - ngaphandle kweespikes ezimbalwa. Onke amaza amaza (i-spectrum epheleleyo) aphinde abekhona kodwa kuphela amaza amaza athile (izispiki) akhoyo ngamandla. Ezi spikes zibonisa ukuba zeziphi iindawo zombala eziya kugxininiswa kunikezelo lombala kwizinto ezikhanyiswe ngumthombo wokukhanya. Esi sibane sinobushushu bombala we-2700K kunye ne-CRI ye-82. Ivelisa ukukhanya okubonwa "njengokufudumala" kunokukhanya kwemini (2700K vs. 5000K). Ukukwazi kwayo ukunika umbala kwi-spectrum akubi, kodwa ngokuqinisekileyo kubi kakhulu kunokukhanya kwemini.

Usebenza njani umbala?

Imithombo yokukhanya inokwahlulwa ibe yimithombo yokukhanya eyenziweyo okanye eyendalo. Kwiimeko ezininzi, sixhalabile malunga nomgangatho wombala weendlela zokukhanyisa ezenziweyo, ezifana ne-LED kunye nezibane ze-fluorescent. Oku kuthelekiswa nokukhanya kwemini okanye ukukhanya kwelanga - umthombo wokukhanya wendalo.

Ukukhanya kwendalo, njengokukhanya kwelanga, kudibanisa yonke imibala ye-spectrum ebonakalayo. Umbala wokukhanya kwelanga ngokwawo umhlophe, kodwa imibala imisela umbala wento ephantsi kwelanga ewubonakalisayo.

Ngokomzekelo, iapile elibomvu libonakala libomvu kuba lifunxa yonke imibala yombala ngaphandle kobomvu, nto leyo ebonakalisayo.

Xa sisebenzisa umthombo wokukhanya owenziweyo njengesibane se-LED, sizama "ukuvelisa" imibala yokukhanya kwemini yendalo ukuze izinto zibonakale zifana njengoko zenza phantsi kokukhanya kwelanga kwendalo.

Ngamanye amaxesha, umbala owenziwe ngokutsha uya kubonakala ufana, ngamanye amaxesha ahluke kakhulu. Kukufana oku kulinganisa i-CRI.

Umzekelo wethu ongentla ubonisa ukuba umthombo wethu wokukhanya wokufakelwa (isibane se-LED kunye ne-5000K CCT) ayivelisi ubomvu obufanayo kwi-apula ebomvu njengokukhanya kwemini yendalo (kunye ne-5000K CCT).

Kodwa qaphela ukuba isibane se-LED kunye nemini yendalo inombala ofanayo we-5000K. Oku kuthetha ukuba umbala wokukhanya uyafana, kodwa izinto zisabonakala zahlukile. Inokwenzeka njani loo nto?

Ukuba ujonga umzobo wethu apha ngasentla, uya kubona ukuba isibane sethu se-LED sinokwakheka okubonakalayo okwahlukileyo kunokukhanya kwemini yendalo, nangona ifana nombala omhlophe we-5000K.

Ngokukodwa, isibane sethu se-LED siswele ebomvu. Xa oku kukhanya kugqabhuza kwi-apile ebomvu, akukho sibane sibomvu esibonakalisayo.

Ngenxa yoko, iapile elibomvu alisenayo inkangeleko ebomvu efanayo naleyo lalinayo phantsi kokukhanya kwemvelo kwemini.

I-CRI izama ukubonisa le nto ngokulinganisa ukuchaneka ngokubanzi kwemibala yezinto ezahlukeneyo xa kukhanyiswa phantsi komthombo wokukhanya.

I-CRI ayibonakali de uyikhanyise entweni

Njengoko kukhankanyiwe ngasentla, umbala ofanayo wokukhanya unokuba nokwakheka okungafaniyo kwe-spectral.
Ke ngoko, awukwazi ukugweba i-CRI yomthombo wokukhanya ngokujonga nje umbala wokukhanya. Kuya kubonakala kuphela xa ukhanyisa ukukhanya kwizinto ezahlukeneyo ezinemibala eyahlukeneyo.

Ilinganiswa njani i-CRI?

I-CRI ilinganiswa kusetyenziswa indlela esemgangathweni yoshishino ephuhliswe yiCIE. Oku kubandakanya uthelekiso lomthombo wovavanyo lombala wovavanyo kumthombo wesalathiso owaziwa ngokuba yiradiyetha yomzimba omnyama kunye nenqaku eligqibeleleyo le-CRI le-100. Kolu vavanyo, kukho iisampulu zereferensi eziphambili ezilishumi elinesihlanu ezisetyenziselwa ukubala ukalisho lwe-CRI ngokubanzi. Isampulu ekhethiweyo yomthombo wereferensi ixhomekeke kubushushu bombala wesibane esivavanywayo. Itshathi yeColorChecker, esekwe yiCIE (1999), ihlela le mithombo yolwazi kwaye iyilungelelanise ngokwamanani iqala ngeTCS01 kwaye iphele ngeTCS15. Ukusondela komthombo ovavanywayo uhambelana nomthombo wesalathiso ogqibeleleyo, kokukhona uya kufakwa kwinqanaba le-CRI.

Sithelekisa imibala ebonakalisiweyo kwaye simisela ngokwefomula isitshixo sombala ngasinye amanqaku “R”.

Ixabiso elingu-R lombala othile libonisa amandla omthombo wokukhanya ukunika ngokuthembekileyo loo mbala uthile. Ngoko ke, ukubonisa umbala opheleleyo wesakhono somthombo wokukhanya kwiintlobo ngeentlobo zemibala, ifomula ye-CRI ithatha umndilili wamaxabiso e-R.

I-Ra yi-avareji yexabiso le-R1 ukuya kwi-R8.

I-AvgR yi-avareji yexabiso le-R1 ukuya kwi-R15.

Ixabiso elikhethekileyo: R9

I-Ra yi-avareji yexabiso le-R1–R8; amanye amaxabiso ukusuka kwi-R9 ukuya kwi-R15 awasetyenziswanga ekubaleni iRa, kuquka i-R9 “ebomvu ehluthisiweyo”, i-R13 “umbala wesikhumba (ukukhanya)”, kunye ne-R15 “umbala wesikhumba (ophakathi)”, yonke imibala enzima ukuyivelisa ngokuthembekileyo. I-R9 isalathiso esibalulekileyo ekukhanyeni kwe-CRI ephezulu, njengoko izicelo ezininzi zifuna izibane ezibomvu, ezifana nefilimu kunye nokukhanya kwevidiyo, ukukhanya kwezonyango, ukukhanya kobugcisa, njl.

I-R9 yenye yamanani e-Ri ebhekisela kwiisampuli zemibala yovavanyo (TCS), elinqaku elinye kwi-CRI eyandisiweyo. Linani lemilinganiselo yomthombo wokukhanya wokuveza umbala ukuya kwi-TCS 09. Kwaye ichaza umthamo othile wokukhanya ukuvelisa kwakhona umbala obomvu wezinto ngokuchanekileyo. Abenzi bokukhanya abaninzi okanye abathengisi abawabonisi amanqaku e-R9. Ngexesha elifanayo, lixabiso eliqinileyo lokuvavanya ukusebenza kombala wokuguqulwa kwefilimu kunye nokukhanya kwevidiyo kunye naziphi na izicelo ezifuna ixabiso eliphezulu le-CRI. Ke, ngokuqhelekileyo, ithathwa njengesongezelelo kwisalathiso sokunikezela ngombala xa uvavanya umthombo wokukhanya we-CRI ephezulu.

Ixabiso le-R9, i-TCS 09, okanye ngamanye amazwi, umbala obomvu ngumbala oyintloko kwizicelo ezininzi zokukhanyisa, ezifana nefilimu kunye nokukhanya kwevidiyo, ukuprintwa kwe-textile, ukuprintwa komfanekiso, ithoni yesikhumba, ukukhanya kwezonyango, njalo njalo. Ngaphandle koko, ezinye izinto ezininzi azikho kumbala obomvu, kodwa eneneni ziquka imibala eyahlukeneyo, kuquka umbala obomvu. Umzekelo, ithoni yesikhumba ichatshazelwa ligazi eliphantsi kolusu, nto leyo ethetha ukuba ithoni yesikhumba ikwabandakanya nombala obomvu, nangona ikhangeleka ngathi ikufutshane kumhlophe okanye kumthubi okhanyayo. Ngoko ke, ukuba ixabiso le-R9 alilungile ngokwaneleyo, ithoni yesikhumba phantsi kwesi sibane iya kuba luhlaza ngakumbi okanye ibe luhlaza emehlweni akho okanye kwiikhamera.

Kuthekani ngamaqondo obushushu bemibala engeyoyasemini?

Ukwenza lula, sithathe i-5000K yobushushu bombala kwimizekelo yethu engentla kwaye siyithelekise ne-5000K yendalo yokukhanya kwemini yezibalo ze-CRI.

Kodwa kuthekani ukuba sinesibane se-3000K se-LED kwaye sifuna ukulinganisa i-CRI yayo?

Umgangatho we-CRI uyalela ukuba ubushushu bombala bube yi-5000K kunye nokusetyenziswa okukhulu kokukhanya kwemini, kodwa kubushushu bombala obungaphantsi kwe-5000K, sebenzisa i-Planckian radiation spectrum.

Imitha yePlanckian yeyona ndawo yokukhanya eyenza ukukhanya ngokuvelisa ubushushu. Oku kubandakanya imithombo yokukhanya ye-incandescent kunye ne-halogen.

Ngoko xa silinganisa i-CRI yesibane se-3000K se-LED, sigwetywa ngokuchasene nomthombo wokukhanya "wendalo" kunye ne-spectrum efanayo ne-3000K ye-halogen spotlight.

(Kunjalo kanye – nangona amandla awongayo e-halogen kunye neebhalbhu ze-incandescent, zivelisa ukukhanya okugcweleyo, kwendalo kunye nokugqwesileyo).
