Ruvara Rendering Index (CRI) inzira yakabatana yepasi rose yekutsanangura kuratidzwa kwemavara echiedza. Yakagadzirirwa kupa ongororo chaiyo yehuwandu hwekuti ruvara rwechinhu chiri pasi pechiedza chakayerwa runoenderana sei neruvara rwunoratidzwa pasi pechiedza. Commission internationale de l 'eclairage (CIE) inoisa indekisi yechiedza chezuva pa100, uye indekisi yemwenje yeincandescent iri pedyo zvikuru nechiedza chemasikati uye nokudaro inoonekwa senzvimbo yakanaka yechiedza.
CRI chinhu chakakosha pakuyera kugona kwechiedza kuburitsa ruvara rwechinhu. Kana CRI yakakwira, simba rechiedza kudzoreredza ruvara rwechinhu rakasimba, uye zviri nyore kuti ziso remunhu rione ruvara rwechinhu chacho.
CRI inzira yekuyera mashandiro echiedza mukuziva mavara zvichienzaniswa nechiedza chakajairika (senge chiedza chemasikati). Ndiyo nzira inogamuchirwa nevakawanda uye ndiyo chete nzira yekuongorora nekupa rondedzero yemavara echiedza. Kuratidza mavara iongororo yemhando yepamusoro inoyera mwero wekuti chiedza chinoratidza ruvara rwechinhu, kureva kuti, kuburitsa mavara kwacho kuri kwechokwadi sei.
Kuratidzwa kwemavara ane Mwenje Mukuru (CRI≥90) kunogona kuburitsa chiedza chakapfava, zvinobudirira kuderedza kuneta kwekuona, kuita kuti nzvimbo yekuona ijeke uye mufananidzo uve nemativi matatu; zvichipa vashandisi ruzivo rwemavara akakwirira uye chiedza chekunze chakareruka. Kuratidzwa kwemavara akakwirira kune mhedzisiro yakanaka yekuburitsa mavara, uye mavara atinoona ari pedyo nemavara ekutanga echisikigo (mavara ari pasi pezuva); kuratidzwa kwemavara akaderera kune mhedzisiro isina kunaka yekuburitsa mavara, saka kusiyana kwemavara kwatinoona kwakakura.
Ungasarudza sei kupenda mavara/kuratidza mavara paunenge uchitenga michina yemwenje?
Pakusarudza kuratidzwa kwemavara, misimboti miviri inowanzo teverwa, inova musimboti wekuratidza mavara nenzira yakatendeka uye musimboti wekuratidza mavara zvinobudirira.
(1) Nheyo yekupa mavara akatendeka
Nheyo yekunyora mavara akatendeka inoreva kuti kuti iratidze ruvara rwepakutanga rwechinhu nemazvo, panofanira kusarudzwa chiedza chine indekisi yekuratidza mavara akakwira. Muchiitiko ichi, sarudzo inogona kuitwa zvichibva paRa value. Kana Ra value yakakura, chiyero chekudzoreredza ruvara rwepakutanga rwechinhu chacho chakakwira. Mashandisirwo akasiyana ane zvinodiwa zvakasiyana zvekupenda mavara akatendeka emavara echiedza.
Zvichienderana nenzvimbo dzakasiyana dzinoshandiswa, International Commission on Illumination (CIE) inokamura indekisi yekupa mavara muzvikamu zvishanu:
| Chikamu chekuratidzwa kwemavara | Kukosha kweRa | kuratidzwa kwemavara | Mashandisirwo azvo/zvinodiwa pakuratidzwa kwemavara |
| 1A | 90-100 | zvakanakisisa | Kana paine musiyano chaiwo wemavara unodiwa |
| 1B | 80-89 | kugona | Kana kudikanwa kwemavara epakati nepakati |
| 2 | 60-79 | zvakajairika | Kana kudikanwa kwemavara epakati nepakati |
| 3 | 40-59 | hurombo hwakanyanya | Nzvimbo dzine zvinodiwa zvishoma zvekudhirowa kwemavara |
| 4 | 20-39 | murombo | Nzvimbo dzisina zvinodiwa zvakananga zvekupa mavara |
(2) Musimboti weruvara rwakakosha
Nheyo yekushandiswa kwemavara ndeyekuti muzvikamu zvakasiyana-siyana zvakaita semakabati ekuratidza nyama, kuti mavara aonekwe uye kuti zvinhu zvionekwe zvakanaka, panofanira kusarudzwa chiratidzo chemavara chaiwo. Pachishandiswa kuona kuti kukosha kweRa kunoenderana nezvinodiwa, chiratidzo chemavara chaiwo chinoenderana chinowedzerwa zvichienderana neruvara rwechinhu chakavhenekerwa.
Munzvimbo dzinoratidzwa nyama muzvitoro zvikuru nezvitoro zvakasiyana-siyana, chiratidzo chemavara R9 chechiedza chinonyanya kukosha, nekuti ruvara rwenyama runowanzova rutsvuku, uye R9 yakakwira inogona kuita kuti nyama ive nemaonero matsva uye anonaka.
Pazviitiko zvakaita sezvikamu zvemitambo nemastudio zvinoda kudzokororwa kwakarurama kwemavara eganda, chiratidzo chemavara R15 chechiedza chinofanira kusangana nemazinga epamusoro.

Chiratidzo chemavara emwenje yeincandescent i100. Zvisinei, muhupenyu, kune mhando dzakawanda dzemwenje yeincandescent ine mashandisirwo akasiyana. Nokudaro, kukosha kwayo kweRa hakuna kufanana. Inogona kungonzi iri pedyo ne100, iyo inoonekwa sechiedza chine mashandiro akanaka ekupenda mavara. Zvisinei, rudzi urwu rwechiedza haruna kushanda zvakanaka uye haruna zvakanakira kuchengetedza simba uye kuchengetedzwa kwezvakatipoteredza. Kusiyana neizvi, kunyange zvazvo mwenje ye LED yakaderera zvishoma pane mwenje yeincandescent maererano nekushanda kwekupenda mavara, yava sosi yechiedza yakakurumbira nekuda kwehunhu hwayo hwekuchengetedza simba uye hune hushamwari kune zvakatipoteredza.
Pamusoro pezvo, kana muviri wemunhu ukasangana nenzvimbo ine chiedza chisina kunaka kwenguva yakareba, kunzwa kwemasero ekona yeziso remunhu kunoderera zvishoma nezvishoma, uye uropi hunogona kutarisisa zvakanyanya pakuziva zvinhu, izvo zvinogona kukonzera kuneta kwemaziso uye kunyange myopia.
Rudzi rwemavara rwezvinobva mumwenje yekirasi harufanirwe kunge rwakaderera kupfuura 80. Rudzi rwemavara rwakanyanya kuderera rwemwenje yekirasi runokanganisa kuona kwemaziso evadzidzi ruvara rwezvinhu, zvichiita kuti zvinhu zvisakwanise kuratidza mavara azvo chaiwo. Kana mamiriro ezvinhu aya akaramba kwenguva yakareba, zvichakonzera kudzikira nekuderera kwekugona kusiyanisa mavara, izvo zvichakonzera matambudziko makuru ekuona nezvirwere zvemaziso muvadzidzi zvakaita sekusaona mavara uye kushaya simba kwemavara.
Ruvara rwekuratidzwa kweRa>90 runoshandiswa pakuisa chiedza muhofisi, kugutsikana kwaro pakuonekwa kunogona kuderedza kupenya kweanopfuura 25% kana tichienzanisa nemwenje ine rambi rekuratidza ruvara rushoma (Ra<60). Ruvara rwekuratidzwa kwechiedza pamwe chete nechiedza zvinobva kuchiedza zvinosarudza kujeka kwenzvimbo, pane hukama hwakaenzana pakati pekujeka neruvara rwekuratidzwa kwemavara.
