CRI ni iki & nigute wahitamo ibikoresho byo kumurika?

Ibipimo byerekana amabara (CRI) nuburyo mpuzamahanga bwahujwe bwo gusobanura ibara ryerekana amasoko yumucyo. Yashizweho kugirango itange isuzumabumenyi nyaryo ryerekana urwego ibara ryikintu munsi yumucyo wapimwe rihuye nibara ryatanzwe munsi yumucyo. Komisiyo mpuzamahanga ya l 'eclairage (CIE) ishyira ibara ryerekana ibara ryerekana urumuri rw'izuba ku 100, kandi ibara ryerekana amabara yerekana amatara yaka cyane ryegereye cyane ku manywa y'ihangu bityo rikaba rifatwa nk'isoko ryiza ryerekana urumuri.

CRI nikintu cyingenzi cyo gupima ubushobozi bwumucyo wo kubyara ibara ryikintu. Agaciro gakomeye CRI, imbaraga zubushobozi bwumucyo wo kugarura ibara ryikintu, kandi byoroshye ko ijisho ryumuntu ritandukanya ibara ryikintu.

CRI nuburyo bwo gupima imikorere yumucyo mumenyekanisha amabara ugereranije numucyo usanzwe (nkumucyo). Nibipimo byemewe cyane nuburyo bwonyine bwo gusuzuma no gutanga raporo yerekana ibara ryerekana urumuri. Guhindura amabara ni isuzuma ryujuje ubuziranenge ripima urwego isoko yumucyo yerekana ibara ryikintu, ni ukuvuga uburyo ibara ryororoka ari ukuri.
Ibara ryinshi ryerekana amabara (CRI≥90) rishobora kubyara urumuri rworoshye, kugabanya neza umunaniro ugaragara, bigatuma umurima wicyerekezo ugaragara neza kandi ishusho ikagira ibice bitatu; kuzana abakoresha ibara ryinshi ryerekana kandi ryoroheje ryo kumurika hanze. Guhindura amabara maremare bifite ingaruka nziza zo kororoka, kandi amabara tubona yegereye amabara yibanze (amabara munsi yizuba); ibara rito ryerekana rifite amabara mabi yimyororokere, bityo gutandukana kwamabara tubona binini.

Nigute ushobora guhitamo ibara ryerekana amabara mugihe ugura ibikoresho byo kumurika?

Iyo uhisemo gushushanya amabara, amahame abiri akurikizwa, aribwo ihame ryo gutanga amabara yizerwa hamwe nihame ryo gutanga amabara meza.

（1 principle Ihame ryo gutanga amabara yizerwa

Ihame ryo kwerekana amabara yizerwa bisobanura ko kugirango ugaragaze neza ibara ryumwimerere wikintu, isoko yumucyo hamwe nurwego rwo hejuru rwerekana amabara agomba guhitamo. Muri iki kibazo, guhitamo birashobora gukorwa hashingiwe ku gaciro ka Ra. Ninini ya Ra agaciro, niko urwego rwo kugarura ibara ryumwimerere ryikintu. Porogaramu zitandukanye zifite ibisabwa bitandukanye kugirango amabara yizerwa atanga isoko yumucyo.

Ukurikije ahantu hatandukanye hashobora gukoreshwa, Komisiyo mpuzamahanga ishinzwe kumurika (CIE) igabanya ibipimo byerekana amabara mu byiciro bitanu:

（2） Ihame ryamabara

Ihame ryingaruka zerekana amabara ni uko mubice byihariye nkibicuruzwa byinyama byerekana akabati, kugirango ugaragaze amabara yihariye kandi werekane ubuzima bwiza, urutonde rwihariye rwo gutanga amabara rugomba guhitamo. Hashingiwe ku kwemeza ko Ra agaciro yujuje ibisabwa, indangagaciro yihariye yo gutanga amabara yiyongera ukurikije ibara ryikintu kimurikirwa.

Ahantu herekanwa inyama za supermarket hamwe nububiko butandukanye, indangagaciro yo gutanga amabara R9 yinkomoko yumucyo irakomeye cyane, kuko ibara ryinyama risanzwe ribogamye kumutuku, kandi R9 yo hejuru irashobora gutuma inyama zigaragaza ingaruka nziza kandi ziryoshye ziboneka. .

Kumashusho nkibikorwa byimikorere na sitidiyo bisaba kubyara neza imiterere yuruhu, indangagaciro yo gutanga amabara R15 yumucyo igomba kuba yujuje ubuziranenge.

KwaguraKubumenyi

Ibara ryerekana amabara yerekana amatara yaka ni 100. Ariko, mubuzima, hariho ubwoko bwinshi bwamatara yaka kandi akoreshwa muburyo butandukanye. Kubwibyo, indangagaciro zabo Ra ntabwo ari zimwe. Birashobora kuvugwa gusa kuba hafi 100, ifatwa nkisoko yumucyo hamwe nibikorwa byiza byo gutanga amabara. . Nyamara, ubu bwoko bwumucyo butanga urumuri ruke kandi ntibufite ibyiza byo kuzigama ingufu no kurengera ibidukikije. Ibinyuranye, nubwo amatara ya LED ari munsi gato y’itara ryaka cyane mu bijyanye no gutanga amabara, byahindutse isoko yumucyo uzwi cyane kubera kuzigama ingufu no kubungabunga ibidukikije.

Byongeye kandi, niba umubiri wumuntu uhuye nibidukikije bimurika kandi bidakora neza mugihe kirekire, ibyiyumvo byingirabuzimafatizo ya cone yijisho ryumuntu bizagenda bigabanuka buhoro buhoro, kandi ubwonko bushobora kwibanda cyane kubushake mugihe cyo kumenya ibintu, bushobora byoroshye gutera umunaniro w'amaso ndetse na myopiya.

Ibara ryerekana ibara ryerekana amatara yo mwishuri ntirigomba kuba munsi ya 80.Ibara rike cyane ryerekana urumuri rwishuri bizagira ingaruka kumaso yabanyeshuri kumenya neza ibara ryibintu, bigatuma ibintu bidashobora kwerekana amabara yumwimerere. Niba ibi bintu bikomeje igihe kirekire, bizatera kugabanuka no kugabanuka kwubushobozi bwo kuvangura amabara, ibyo bikazatera ibibazo bikomeye byo kureba nindwara zamaso mubanyeshuri nko guhuma amabara no kutagira ibara.

Ibara ryerekana amabara Ra> 90 rikoreshwa mukumurika ibiro, kunyurwa kwayo birashobora kugabanya kumurika kurenga 25% ugereranije nibikoresho bimurika hamwe n'amatara maremare yerekana itara (Ra <60). Ibara ryerekana amabara hamwe no kumurika isoko yumucyo hamwe bigena icyerekezo kiboneye cyibidukikije, hariho isano iringaniye hagati yo kumurika no kwerekana amabara.
