Kuti unzwisise CRI uye lumens

Sezvimwe nezvimwe zvakawanda zvesainzi yeruvara, isu tinofanira kudzokera kune spectral simba rekugovera kwechiedza.
CRI inoverengerwa nekuongorora spectrum yechiedza sosi uyezve kuenzanisa nekuenzanisa spectrum iyo inogona kuratidza kubva pane seti yemasampuli eruvara rwebvunzo.
CRI inoverenga masikati kana mutsvuku wemuviri SPD, saka CRI yakakwirira inoratidza kuti chiedza chechiedza chakafanana nemasikati masikati (yakakwirira CCTs) kana halogen / incandescent lighting (pasi CCTs).

Kupenya kwechiedza chechiedza kunotsanangurwa nekubuda kwaro kwakajeka, kunoyerwa nelumens. Kupenya, kune rumwe rutivi, chivakwa chemunhu! Inotaridzirwa newavelengths iyo maziso edu anonyanya kunzwa uye huwandu hwesimba rechiedza riripo mune izvo wavelengths. Tinodaidza ultraviolet uye infrared wavelengths "asingaoneki" (kureva, pasina kupenya) nekuti maziso edu haango "nhonga" aya wavelengths sekupenya kunoonekwa, zvisinei nekuti rakawanda sei simba ririmo mazviri.
Basa reLuminosity

Masayendisiti mukutanga kwezana ramakore rechimakumi maviri akagadzira mhando dzemagadzirirwo ekuona kwevanhu kuti vanzwisise zviri nani kuti chiitiko chekupenya chinoshanda sei, uye musimboti wakakosha uri shure kwayo ibasa rechiedza, iro rinotsanangura hukama pakati pewavelength uye maonero ekupenya.

Iyo yero curve inomiririra yakajairwa photopic basa (pamusoro)
Iyo luminosity curve inokwira pakati pe545-555 nm, iyo inoenderana neirime-yegirini ruvara wavelength renji, uye inokurumidza kudonha kubva kumusoro uye kuzasi wavelengths. Nekutsoropodza, kupenya kwakadzika zvakanyanya kudarika 650 nm, iyo inoenderana neruvara rutsvuku wavelengths.
Izvi zvinoreva kuti ruvara rutsvuku rwewavelengths, pamwe nerima rebhuruu uye violet color wavelengths, haashande pakuita kuti zvinhu zviratidzike zvakajeka. Green uye yellow wavelengths, kune rumwe rutivi, ndiyo inonyanya kushanda pakuonekwa yakajeka. Izvi zvinogona kutsanangura kuti sei mavhasi ekuchengetedza epamusoro-soro uye mavhenekeri anowanzo shandisa yero/girinhi mavara kuti awane kupenya kwavo.
Chekupedzisira, kana tichienzanisa basa rekupenya kune spectrum yemasikati chaiwo, zvinofanirwa kuve pachena kuti nei yakakwirira CRI, kunyanya R9 yezvitsvuku, iri kupesana nekupenya. Iyo yakazara, yakafara spectrum inenge inogara ichibatsira kana uchitsvaga yakakwirira CRI, asi nhete inotariswa mugirinhi-yero wavelength renji inozonyanya kushanda kana uchitsvaga yakakwirira inopenya kushanda.

Rudzi rwemhando uye CRI dzinenge dzagara dzakaiswa pamberi mukutsvaga kwekushandisa simba nekuda kweichi chikonzero. Kutaura chokwadi, mamwe maapplication, akadaichiedza chekunze, inogona kuisa simbiso huru pakubudirira kupfuura kuburitsa mavara. Kunzwisisa uye kukoshesa fizikisi inobatanidzwa, kune rumwe rutivi, inogona kubatsira zvakanyanya mukuita sarudzo ine ruzivo mukuiswa kwemwenje.
