Ruvara rekupa index (CRI) ye LED mitsetse
2024-09-13 14:33:34
Colour rendering index (CRI) ndiyo inowanzoshandiswa parameter mumunda wemagetsi ekuvheneka. Rinoreva mwero wemwero wekuti ruvara rwechinhu chinoenderana sei kana chavhenekerwa nechiedza ichi uye kana chavhenekerwa nechiedza chemazuva ese (kazhinji chinoshandisa chiedza chezuva semanyuko echiedza), ndiko kuti, sei. realistic the color is.
1.CRI tsananguro
Kune varapi vemwenje, color rendering index (CRI) izwi rinowanzoshandiswa. Isu tinowanzoona kukosha kweCRI mu data yezviedza, uye tinoziva kuti inoratidza kunaka kwechiedza chechiedza maererano nekupa kwemavara.
Asi zvinorevei chaizvoizvo? Iko CRI kukosha kunobatsira kuona kuti ndeipi sosi yemwenje inofanira kushandiswa mumudziyo wekuvhenekesa. Iyo yakakwirira iyo CRI kukosha, zviri nani, asi vanhu vanoziva here kuti chii chainoyera uye kuti inoyera sei? Semuenzaniso, kukosha kweCRI ye OLIGHT S1MINI ndeye 90. Izvi zvinopa ruzivo rupi? Hunhu hwekuvhenekesa kwemuseum hunofanirwa kunge huri pamusoro peCRI 95. Sei?
Kungotaura zviri nyore: kuburitsa ruvara chinhu chakakosha pakuongorora kunaka kwemwenje, uye mavara ekuratidza indekisi inzira yakakosha yekuongorora maratidziro eruvara rwemwenje. Iyo yakakosha parameter yekuyera mavara emavara emagetsi ekugadzira magetsi. Kana indekisi yekupa ruvara yakakwira, zvinoita kuti chiedza chiratidzirwe zviri nani. Izvo zviri nani ruvara, iyo yakasimba simba rekudzorera ruvara rwechinhu.
Sangano reInternational Commission on Illumination (CIE) rinotsanangura ratidziro yeruvara se: mhedzisiro yechiedza pachimiro cheruvara rwechinhu zvichienzaniswa neyakajairwa referensi mwenje sosi.
Mune mamwe mazwi, CRI inzira yekuyeresa yekuzivikanwa kweruvara rwemwenje sosi kana ichienzaniswa neyakajairwa mwenje sosi (yakadai semasikati). CRI ndiyo metric inozivikanwa pasi rose uye ndiyo chete nzira yekuongorora uye kushuma kupihwa kweruvara kwechiedza sosi. nzira.
Kugadzwa kweCRI metric standard hakusi kure. Chinangwa chekutanga chekumisikidza chiyero ichi chaive chekuishandisa kutsanangura mavara ekupa zvimiro zvemwenje wefluorescent aishandiswa zvakanyanya muma1960s, uye kubatsira vashandisi kunzwisisa kuti marambi efluorescent ane linear spectral kugovera anogona kushandiswa mune zvipi zviitiko.
2.CRI tekinoroji
Kunyangwe aya mavara emavara akanyatso kutsanangurwa uye zvinhu chaizvo zvinogona kuburitsa mavara eaya maswachi, zvakakosha kuti unzwisise kuti iwo CRI hunhu hunotorwa zvachose kuburikidza nekuverenga uye hazvireve kuvhenekera iyo chaiyo ruvara swatch ine chaiyo mwenje sosi.
Chatinofanira kuita kushandisa chiyereso chakayerwa chinobva kuchiedza kuenzanisa nerukova rwesample yeruvara rwakatarwa, tobva tatora nekuverenga kukosha kweCRI kuburikidza nekuongorora masvomhu.
Naizvozvo, kuyerwa kweCRI kukosha kwehuwandu uye chinangwa. Hachisi chiyereso chekuzvimiririra (chiyero chemusoro chinoenderana chete nemucherechedzi akadzidzira kutonga kuti ndechipi chiedza chine mavara ari nani).
Kuenzanisa kwakavakirwa pakuona kweruvara kune zvakunorevawo, chero tembiricha yeruvara yezvose zvakayerwa mwenje sosi uye referenzi mwenje sosi inofanira kufanana.
Semuenzaniso, kuedza kuenzanisa kutaridzika kwemavara maviri akafanana akavhenekerwa nechiedza chichena chinodziya chine tembiricha yeruvara inosvika 2900K uye nechiedza chichena chinotonhorera (masikati) chine tembiricha yemavara ye5600K kutambisa nguva.
Dzinofanirwa kutaridzika zvakasiyana, saka tembiricha yeruvara yakabatana (CCT) yemwenje wakayerwa sosi inoverengerwa kubva muchikamu chechiedza. Paunenge uchinge uine iyi tembiricha yeruvara, imwe referensi mwenje sosi yemhando imwechete tembiricha inogona kugadzirwa nemasvomhu.
Kune yakayerwa mwenje sosi ine tembiricha yeruvara yakaderera pane 5000K, iyo referenzi mwenje sosi iblackbody (Planck) radiator, uye kune yakayerwa sosi yemwenje ine tembiricha yeruvara yakakwira kupfuura 5000K, iyo referensi mwenje sosi iCIE yakajairwa illuminant D.
Sarudzo inogona kusanganisa spectrum yereferensi mwenje sosi neyega yega sampuli kuti ibudise seti yeakanakisa referensi color coordinate points (mavara mapoinzi epfupi).
Zvimwe chetezvo kune chitubu chechiedza chiri pasi pekuedzwa. Chiyero chechiedza chechiedza chinosanganiswa nesample yeruvara rwega-ega kuti uwane imwe seti yemapoinzi eruvara. Kana nzvimbo yeruvara iri pasi pechiedza chakayerwa sosi ichinyatsoenderana nenzvimbo yeruvara iri pasi pereferensi mwenje sosi, isu tinoona iwo mavara ekupa mavara akafanana toseta CRI yavo ku100.
Muchati cheruvara, nzvimbo yeruvara iri kure pasi pechiedza chakayerwa chinobva panzvimbo inoenderana yakafanira, ndiko kushata kuri kuita ruvara uye kuderera ukoshi hwe CRI.
Verenga kusimuka kwemavara epairi masere emasampuli eruvara zvakasiyana, wobva waverenga 8 yakakosha mavara ekupa indexes (iyo CRI kukosha kwemwenje sosi yeimwe ruvara sampu inonzi special color rendering index), wobva watora masvomhu avo, saka. kukosha kwakawanikwa ndeye CRI kukosha.
A CRI value ye100 zvinoreva kuti hapana musiyano weruvara pakati pemhando ipi neipi yemasamples emavara mumapeya masere emasample eruvara pasi pechiedza chakayerwa sosi uye referenzi mwenje sosi.
3.Ko indekisi yekupa ruvara yemwenje ye LED inoenderana nei?
Iyo color rendering index yemwenje ye LED inonyanya kuenderana nemhando uye chiyero chephosphors. Hunhu uye chiyero chephosphors chine kukosha kwakakosha pane iyo ruvara inopa index yemwenje ye LED. Yepamusoro-mhando phosphors inogona kupa zvirinani tembiricha yemavara uye diki tembiricha tembiricha inodonha, nekudaro ichivandudza iyo ruvara inopa index. 12
Ikozvino yekutyaira ichakanganisawo ruvara rwekupa index yemwenje we LED. Huru yekutyaira ikozvino inokonzeresa tembiricha yeruvara kuti iswedere kune yakakwira tembiricha yemavara, nekudaro ichidzikisa indekisi yeruvara.
Iyo yekupisa yekupisa sisitimu ye LED zvakare ine imwe mhedzisiro pane iyo color rendering index. Iyo inovimbika yekupisa kupisa system inogona kuve yakagadzikana kushanda kwemwenje ye LED uye kuderedza kudzikama kwechiedza uye ruvara rekupa index kuderera kunokonzerwa nekukwira kwekushisa.
Iyo spectral kugovera kwechiedza sosi chinhu chakakosha pakuona iyo color rendering index. Hukuru uye kusimba kwemavara akasiyana-siyana ari muspectrum zvinokanganisa zvakananga indekisi yemavara. Iyo yakafara kugovera kwe spectral, iyo inokwirisa iyo color rendering index, uye zvakanyanya kuitika kwekuita kwemavara.
