Chii chinonzi CRI & maitiro ekusarudza zvigadziriso zvemwenje?

Iyo Colour Rendering Index (CRI) inzira yepasi rose yakabatana yekutsanangura maratidziro eruvara rwemagetsi. Yakagadzirwa kuti ipe ongororo yehuwandu hwemwero wekuti ruvara rwechinhu chiri pasi pechiedza chakayerwa chinopindirana neruvara rwunopihwa pasi pechiratidziro chechiedza. Commission internationale de l 'eclairage (CIE) inoisa indekisi yeruvara rwechiedza chezuva pa100, uye indekisi yeruvara yemarambi emwenje iri padyo neiyo yemasikati saka inoonekwa seyakanakira mwenje sosi.

CRI chinhu chakakosha kuyera kugona kwechivheneko kuburitsa ruvara rwechinhu. Kukosha kweCRI yakakwirira, simba rakasimba rechiedza chekudzorera ruvara rwechinhu, uye zviri nyore kuti ziso remunhu rive nekusiyanisa ruvara rwechinhu.

CRI inzira yekuyera kuita kwechiedza chechiedza mukuzivikanwa kweruvara zvichienzaniswa nemwero wemwenje sosi (senge masikati). Ndiyo metric inogamuchirwa nevakawanda uye ndiyo chete nzira yekuongorora uye kushuma maratidziro eruvara rwechiedza. Kupa ruvara irwodzo rwemhando iyo inoyera mwero wekuti chiedza chinopa ruvara rwechinhu, kureva kuti, kuberekana kwemavara kune chokwadi sei.
High Light color rendering (CRI≥90) inogona kubudisa chiedza chakapfava, inobudirira kuderedza kuneta kwekuona, kuita kuti munda wekuona ujeke uye chifananidzo chiwedzere katatu-dimensional; kuunza vashandisi kupihwa kwemavara epamusoro uye kureruka kwemwenje wekunze. Kupa kwemavara epamusoro kune maitiro akanaka ekubereka, uye mavara atinoona ari padyo nemavara ekutanga echisikigo (mavara pasi pezuva); kuburitsa kweruvara kwakaderera kune kushomeka kwemavara, saka kutsauka kwemavara tinoona kwakakura.

Maitiro ekusarudza mavara ekupa / mavara ekupa index paunenge uchitenga mwenje wemagetsi?

Pakusarudza mashandisirwo emavara, nheyo mbiri dzinowanzoteverwa, zvinoti, nheyo yokutendeka kutsanangura mavara uye nheyo yokushandura mavara kunobudirira.

(1) musimboti wekuburitsa mavara

Nheyo yekuvimbika kwemavara ekushandura inoreva kuti kuti imiririre zvakarurama ruvara rwepakutanga rwechinhu, chiedza chine indekisi yemavara epamusoro inofanira kusarudzwa. Muchiitiko ichi, kusarudzwa kunogona kuitwa zvichienderana neRa value. Iyo yakakura iyo Ra kukosha, iyo yakakwirira dhigirii yekudzoreredza kwemavara ekutanga echinhu. Zvishandiso zvakasiyana-siyana zvine zvinodikanwa zvakasiyana zvekutendeka kwemavara kuburitsa kwemwenje masosi.

Zvinoenderana nenzvimbo dzakasiyana dzinoshanda, International Commission on Illumination (CIE) inokamura indekisi yeruvara muzvikamu zvishanu:

(2) Mhedzisiro yemavara musimboti

Iyo musimboti wekuita kwemavara kupa ndewekuti mune chaiwo mapikicha akadai senyama chigadzirwa anoratidza makabati, kuti utarise mavara chaiwo uye kuratidza hupenyu hwakanaka, yakatarwa ruvara rendering index inoda kusarudzwa. Pahwaro hwekuona kuti kukosha kweRa kunosangana nezvinodiwa, iyo inoenderana yakakosha mavara ekupa index inowedzerwa zvichienderana nemuvara wechinhu chakavhenekerwa.

Munzvimbo yekuratidzira nyama yemasupamaketi uye zvitoro zvakasiyana-siyana, indekisi yeruvara R9 yenzvimbo yekuvhenekesa inonyanya kukosha, nekuti ruvara rwenyama kazhinji rwakarerekera kune rutsvuku, uye R9 yepamusoro inogona kuita kuti nyama ive nyowani uye inonaka yekuona maitiro. .

Pazviratidziro zvakaita sematanho ekuita uye masitudiyo anoda kuburitswa kwakaringana kwemavara eganda, indekisi yemavara ekupa indekisi R15 yemwenje sosi inofanira kusangana nemwero wepamusoro.

Iyo theoretical color rendering index yemwenje incandescent ndeye 100. Zvisinei, muhupenyu, kune marudzi akawanda emarambi emagetsi ane kushandiswa kwakasiyana. Nokudaro, maitiro avo eRa haana kufanana. Inogona kungonzi iri pedyo ne100, iyo inofungidzirwa kuti ndiyo chiedza chechiedza nemhando yakanakisisa yekupa maitiro. . Zvisinei, rudzi urwu rwechiedza chine chiedza chakaderera uye hachina zvakanakira kuchengetedza simba uye kuchengetedza kwezvakatipoteredza. Kusiyana neizvi, kunyange zvazvo magetsi e LED ari pasi zvishoma kune magetsi e-incandescent maererano nekuita kwemavara ekupa maitiro, akave anonyanya kufarirwa chiedza nekuda kwekuchengetedza simba uye kuchengetedza zvakatipoteredza.

Indekisi yemavara ekupa mwenje yenzvimbo dzekuvhenekesa mukirasi haifanire kuve yakaderera kupfuura 80. Kunyanya kuderera kwemavara indekisi yemwenje yemukirasi ichakanganisa maonerwo emeso evadzidzi nemaonerwo eruvara rwezvinhu, zvichiita kuti zvinhu zvitadze kuratidza mavara azvo echokwadi chaiwo. Kana mamiriro ezvinhu aya akaenderera mberi kwenguva yakareba, zvinozokonzera kudzikira nekuderera kwekugona kusarura kwemavara, izvo zvinozoita kuti pave nezvinetso zvakakomba zvekuona uye zvirwere zvemaziso muvadzidzi zvakaita sekupofomara kwemavara uye kushaya simba kwemavara.

Rudzi rwekupa indekisi Ra> 90 inoshandiswa pakuvhenekesa kwehofisi, kugutsikana kwekutaridzika kwayo kunogona kuderedza kuvhenekera kweanopfuura 25% kana ichienzaniswa nemidziyo yekuvhenekesa ine yakaderera color rendering index lamp (Ra <60). Indekisi yemavara ekupa uye kuvhenekera kwechiedza chinobva chabatana zvinotemesa kujeka kwekuona kwemhoteredzo, pane hukama huri pakati nepakati pakati pekuvhenekera nemavara ekuratidza indekisi.
