Ibara ryerekana amabara rifite uruhare runini mwisi yumucyo. Ibipimo byingenzi bikubwira uburyo urumuri rugaragaza ibara ryukuri ryikintu, rifasha abakoresha gusobanukirwa nubwiza nubushobozi bwumucyo.
Gusobanukirwa CRI birashobora kugufasha guhitamo neza amatara mugushiraho. Iyi blog isobanura amakuru yose ukeneye kumenya kuri CRI.
Igisobanuro cyibanze cya CRI
CRI, cyangwa Ibara ryerekana amabara, ni igipimo cyubushobozi bwigikoresho cyo kumurika kubyara amabara nyayo yikintu ugereranije nizuba risanzwe. Urutonde rwa CRI ni 0 kugeza 100, kandi hejuru yagaciro, niko imbaraga zumucyo zifite imbaraga zo kubyara amabara. Niba intera yerekana agaciro ka 100, bivuze ko urumuri rufite amabara meza yerekana, kimwe numucyo usanzwe.
Nigute ushobora kubara CRI?
CIE yerekanye bwa mbere igitekerezo cya CRI ku isi mu 1965. Kubara CRI bishingiye ku bipimo byashyizweho na komisiyo mpuzamahanga ishinzwe kumurika (CIE). By'umwihariko, mu kumurika isoko yumucyo kumurongo wamabara asanzwe, urugero rwo gutandukana kwamabara. Abashinzwe gukoresha itandukaniro riri hagati yumucyo wikizamini hamwe nibisobanuro umunani bisanzwe byerekana amabara. Babara itandukaniro mumabara agaragara kugirango amaherezo bakure agaciro CRI. Gutoya itandukaniro, niko CRI iri hejuru.
Nigute ushobora gupima CRI?
Ubusanzwe CRI ibarwa ukoresheje isesengura ryibara rya CIE-1974. Irimo amabara 14 y'icyitegererezo. Icyitegererezo cyamabara 8 yambere yitwa TCS. TCS ikoreshwa mugupima CRI shingiro. Irimo ingero zamabara yoroshye nkubururu buciriritse, umuhondo-icyatsi, umuhondo wijimye, n umutuku wijimye. Ibisigaye 6 kuri 14 by'icyitegererezo bikoreshwa mugupima isesengura ryamabara yihariye.
Urashobora gupima ibara ryerekana amabara ukurikije izi ntambwe zoroshye:
- Hitamo isoko yumucyo: Menya neza ko urumuri rwikizamini hamwe nurumuri rwerekana bifite ubushyuhe bumwe bwamabara.
- Kumurika icyitegererezo cy'ibara: Reba TCS kumurika kumatara yikizamini no kumurika.
- Gereranya no gutanga amabara: Kubara ibara ritandukanye uhuza ingero zumucyo werekana urumuri.
- Kubara CRI: Gupima itandukaniro hanyuma utange agaciro kumanota CRI (0-100) yumucyo wikizamini.
Kuki CRI ari ngombwa kubakora luminaire?
Abakora Luminaire bakeneye gutanga urumuri rwumucyo hamwe nurwego rwo hejuru rwerekana amabara kugirango barebe ko abakoresha bashobora kubona neza amabara.
Dore impamvu zisobanura akamaro ka CRI:
- Imyumvire iboneye: Ahantu nkibigo byubuvuzi, ahakorerwa ubuhanzi, sitidiyo yo gufotora, hamwe nububiko bugurisha bisaba amatara maremare ya CRI. Ibi bibafasha kubona amabara yukuri yibintu.
- Kongera imbaraga zo kubona neza: Amatara maremare ya CRI atanga uburambe busanzwe bwo kumurika, bityo bikagabanya umunaniro wamaso.
- Kunoza ubwiza: Ahantu hafite ibishushanyo mbonera byubaka bisaba amatara maremare ya CRI kugirango azamure ubwiza rusange bwibi bibanza.
Gushyira mu bikorwa CRI mu bihe bitandukanye
Igipimo gisabwa CRI kiratandukanye kubisabwa. Ibi bivuze ko ahantu hatandukanye hasabwa intera zitandukanye za CRI kugirango zongere urumuri rwazo.
Amatara yo guturamo: Amatara akoreshwa ahantu hatuwe agomba kuba afite CRI ya 80 cyangwa irenga. Uru rutonde rwemeza ko ubona amajwi nyayo yimitako, ibikoresho, hamwe nigenamiterere.
Kumurika: Amaduka acuruza agomba gukoresha amatara hamwe na CRI ya 90 cyangwa irenga. Isura nyayo namabara meza yibicuruzwa bikurura abakiriya benshi kandi byongera ibicuruzwa byawe.
Ubugeni bwubuhanzi hamwe ningoro ndangamurage: Ahantu nkaho harasaba amatara maremare ya CRI (hamwe nu rutonde rwa 95 cyangwa hejuru) kugirango yerekane amabara nyayo nuburyo bugaragara.
Gufotora no gufata amashusho: Muri sitidiyo yo gufotora, amatara agomba kugira CRI ndende kugirango ifate amabara nyayo yibintu nabantu.
Ibikoresho byubuvuzi n amenyo: Abaganga bakeneye urumuri rwinshi hamwe na CRI ndende kugirango basuzume impamvu zitera abarwayi babo kandi bavure neza.
Inganda n’inganda: Aha hantu harasaba kandi amatara maremare ya CRI kugirango amenye amakosa nudusembwa mubicuruzwa hakiri kare.
Kugereranya CRI nibindi bikoresho byerekana urumuri
1. CRI n'ubushyuhe bw'amabara (CCT)
Ubushyuhe bwamabara yombi na CRI nibintu byingenzi bigira ingaruka kumikorere yumucyo, ariko bipima ibintu bitandukanye. Ubushyuhe bwamabara (CCT, Ubushuhe bwamabara afitanye isano) busobanura ibara ryumucyo, nkurumuri rushyushye (2700K) cyangwa urumuri rukonje (5000K), mugihe CRI yibanda kubyukuri byerekana ibara ryimyororokere. Inkomoko yumucyo irashobora kugira ubushyuhe bwamabara menshi hamwe nuburinganire bwamabara menshi, cyangwa irashobora kugira ibara rike ryerekana ubushyuhe bwinshi.
2. CRI no gukora neza
Gukoresha urumuri bivuga imbaraga zingufu zumucyo, mubisanzwe bipimirwa muri lumens kuri watt (lm / W). Inkomoko yumucyo mwinshi ntabwo isobanura byanze bikunze CRI ndende, kandi amatara amwe azigama ingufu atezimbere urumuri rutanga amabara. Kubwibyo, mugihe ukurikirana kuzigama ingufu, akamaro ka CRI ntigishobora kwirengagizwa.
3. CRI no gutandukana kwa chromaticity (Duv)
Duv nikintu cyakoreshejwe mugupima chromaticity itandukana yumucyo, byerekana itandukaniro riri hagati yamabara yumucyo wumucyo numucyo mwiza wera. Nubwo CRI ishobora gupima ubushobozi bwo kororoka kwamabara, Duv irashobora kwerekana ibara rusange ryamabara yumucyo. Cyane cyane mubisobanuro bihanitse, Duv na CRI bigomba gusuzumwa hamwe.
Kugereranya indangagaciro za CRI zumucyo usanzwe
1. Amatara ya LED
Amatara ya LED nimwe mubikoreshwa cyane mumucyo mugihe cya none, kandi indangagaciro za CRI mubisanzwe ziri hagati ya 80-90. Amatara yo mu rwego rwo hejuru LED ashobora kugera kuri CRI irenga 90, ikwiranye n'amatara maremare.
2. Amatara ya Fluorescent
CRI y'amatara gakondo ya fluorescent iri hagati ya 70-85. Nubwo imbaraga zo kuzigama ingufu ari nziza, imikorere yacyo itanga amabara ni mike, kandi ntabwo ikwiriye ibihe hamwe nibisabwa byororoka cyane.
3. Amatara yaka cyane
Agaciro CRI yamatara yaka yegereye 100, arashobora kugarura rwose ibara ryukuri ryibintu. Nyamara, amatara yaka afite ingufu nke kandi bigenda bikurwaho buhoro buhoro.
Imipaka ya CRI
CRI ifatwa nkigikoresho cyingirakamaro cyo gupima, ariko kandi ifite aho igarukira.
- Amabara ntarengwa y'icyitegererezo: Ibisubizo bya CRI mubyukuri bishingiye kuburugero 8 rwamabara gusa. Ibi ntabwo byerekana amabara yagutse kwisi.
- Uburemere bungana: Amabara 8 yose yerekana amabara ya CRI afite uburemere bumwe. Ibi bivuze ko idashobora kwerekana akamaro k'amabara amwe mubisabwa.
- Ibara ry'ubushyuhe bushingiye: Ibisubizo bya CRI birashobora guhinduka hamwe nubushyuhe bwubushyuhe. Ibi bivuze ko porogaramu zifite ubushyuhe butandukanye bwamabara ntishobora kwerekana CRI neza.
- Kubura amakuru yuzuye: Porogaramu zimwe zisaba kwiyuzuzamo, kandi CRI ntabwo ifite ubushobozi bwo gupima ibara ryuzuye.
Nigute ushobora guhitamo CRI ibereye yo kumurika?
Hitamo ukurikije gahunda yo gusaba
Ibihe bitandukanye bifite ibisabwa bitandukanye kuri CRI. Mugihe uhisemo amatara, ni ngombwa gusuzuma ibikenewe byihariye byo gusaba. Muri rusange:
Amatara yo murugo:CRI ≥ 80
Kwerekana ubucuruzi:CRI ≥ 90
Akazi k'umwuga (nk'ubuvuzi, gufotora):CRI ≥ 95
Kugirango uhitemo urumuri rukwiye, ugomba gukurikiza ibintu bimwe kugirango ugere kumabara meza:
Ubushyuhe bw'amabara: Menya neza ko ibara ryibara ryumucyo watoranijwe rikwiranye nibidukikije. Kurugero, urumuri rushyushye rukoreshwa munzu naho urumuri rwera rwera rukoreshwa mubucuruzi.
Ikoreshwa rya tekinoroji: Nyamuneka hitamo ikorana buhanga uko bikwiye, nkuko buri kintu kimurika gifite urwego rutandukanye rwa CRI.
Ibisobanuro by'abakora: Buri gihe ugenzure niba itara wahisemo ryagenzuwe kandi ryapimwe kuri CRI neza.
Ibizaza mu gihe cyo gutanga amabara
Inganda zitanga amabara zagiye zihinduka mugihe runaka. Ubushakashatsi burimo bugamije kunoza sisitemu yo gupima.
- Ibipimo byateye imbere: Ibice nka CQS na TM-30 bitanga ibisobanuro birambuye kandi byukuri byerekana ibisubizo. Kubwibyo, barazwi kurusha CRI.
- Itara rishingiye ku muntu: Abashinzwe iterambere bibanda ku gukora urumuri rushingiye ku bantu. Bafite ubushobozi bwiza bwo gutanga amabara kandi ntacyo byangiza kubuzima bwabantu.
- Ibisubizo byubwenge bwubwenge: Amatara yubwenge aha abakoresha kugenzura byuzuye CRI nubushyuhe bwamabara. Ibi bibafasha guhitamo urumuri kubyo bakeneye.
- Itara rirambye: Igisekuru cyubu cyibanze cyane ku gukoresha ibikoresho birambye. Amatara mashya yangiza ibidukikije atanga amabara meza.
Umwanzuro
Umuntu akeneye gusobanukirwa CRI mbere yo guhitamo neza amatara. Ibi bivuze gusa uburyo ubona ikintu mumucyo nyawo; ayo matara azakwereka uburyo ikintu kizasa nkuko cyaba kiri munsi yacyo. Gushiraho bimwe bisaba amatara maremare ya CRI, mugihe ibindi bisaba amatara make ya CRI. Kubwibyo, ugomba kumenya aho washyira amatara nimpamvu. Ubu buryo, urashobora gufata icyemezo gikwiye mugihe uhisemo CRI ibereye.
At XINSANXING, dutanga amatara yo murwego rwohejuru ari CRI yapimwe. Kubindi bisobanuro, nyamuneka sura urubuga cyangwa utwandikire ukoresheje imeri.
