LED color rendering index

Kuwanda kwevanhu mukusarudza marambi uyemwenje, pfungwa yemavara ekupa indekisi mumaitiro ekusarudza.

Zvinoenderana netsanangudzo ye "Architectural Lighting Design Standards", kuburitsa kwemavara kunoreva mwenje sosi kana ichienzaniswa nereferenzi yakajairwa mwenje sosi, mwenje sosi inopa maitiro eruvara rwechinhu. Indekisi yeruvara inotaridza chiyero chemavara echibviro chechiedza, chinotaridzwa sechiyero chekuenderana pakati peruvara rwechinhu chiri pasi pechiedza chakayerwa uye neruvara rwechinhu chiri pasi pechinongedzo chemwenje manyuko.

International Commission on Illumination (CIE) yakaisa indekisi yeruvara rwechiedza chezuva pa100, uye yakataura mavara ebvunzo gumi nemashanu, vachishandisa R1~R15 kuratidza indekisi yekuratidzira yemavara gumi nemashanu aya zvichiteerana. Inogona kunyatso ratidza ruvara rwekutanga rwechinyorwa chinoda kushandisa yakakwira color rendering index (Ra) yechiedza sosi, kukosha kwayo kuri pedyo ne100, iyo yakanakisa color rendering.

General color rendering indekisi, tora R1 ~ R8 mhando dzeyakajairwa ruvara rendering index yeavhareji kukosha, yakanyorwa saRa, inoratidzira mwenje sosi inoburitsa ruvara. Special color rendering index yakasarudzwa R9 ~ R15 mhando dzeakajairwa mavara masampuli eiyo color rendering index, yakanyorwa seRi.

Kazhinji tinoti iyo color rendering index inowanzoreva iyo general color rendering index, ndiko kuti, kukosha kweRa, zvinoenderana ne "Architectural Lighting Design Standards," izvo zvinopihwa zveRa zvishoma zve80, asi kubva kunzvimbo yehunyanzvi. maonero, isu tinodawo kufunga nezverakakosha rendering index.

Pakati pavo, iyo yakakosha color rendering index R9 ndiko kugona kuratidza yakazara tsvuku, kana uchitengaMwenje we LEDuyemwenjeinoda kubhadhara zvakanyanya kukosha kweR9. Iyo yakakwirira kukosha kweR9, iyo inonyanya kuve yechokwadi ruvara rwemichero, maruva, nyama, nezvimwewo. Kana chiedza chitsvuku chisipo muchiedza, chichakanganisa kunaka kwechiedza chemamiriro ekuvhenekera. Saka chete kana Ra neR9 vane hukuru hwepamusoro panguva imwe chete, iyo yakakwira ruvara rwekupaMwenje we LEDinogona kuvimbiswa.

Tichireva kurudziro yenyika, kana iyo Ra ≥ 80 uye R9 ≥ 0 yemarambi, inogona kunyatsosangana nemavara ekupa index inodiwa pamabasa ezuva nezuva.

Zvinofanira kucherechedzwa kuti vakawandaMwenje we LEDpamusika pari zvino kutengeswa neasina kunaka R9 kukosha, saka iwe unofanirwa kunyatso tarisa iyorambisarudzo. Mukuwedzera, kana mavara ekupa indekisi zvinodiwa zvakakwirira, unogona kusarudza Ra ≥ 90, R9 ≥ 70 marambi.

Kunyanya kuderera kwechiedza chemavara ekupa indekisi kuchakanganisa maziso edu kucherechedzwa kweruvara rwechinhu, zvichikonzera kudzikira kana kudzikira mukuzivikanwa kwemavara, kwenguva refu mune yakashata ruvara inopa mwenje sosi, ziso remunhu cone cell senitivity ichaderedzwawo, nyore. kuunza kuneta kwekuona, uye kunyange kukonzera myopia.

Naizvozvo, kusarudza marambi ane ruvara rwepamusoro rendering index kunogona kudzivirira maziso edu uye kutiunzira nharaunda yechiedza yakasununguka tichivandudza kuberekana kwemavara ezvinhu.
