Inkomba Yokunikeza Umbala (CRI) vs Ithempelesha Yombala

Eminyakeni embalwa edlule, kube nokudideka okuphelele mayelana nomehluko phakathi kwenkomba yokunikeza umbala nezinga lokushisa lombala. Kodwa kulesi sihloko, sizocacisa ukungabaza kwakho kokubili futhi senze ukuqonda kwakho lokhu kube lula.

Uyini umbala ngokujwayelekile?

Umbala awuyona into engaphezu kwempahla yokukhanya engabonwa ngeso lenyama. Kubaluleke kakhulu ukuqaphela ukuthi ngisho nezinto ezicacile kakhulu ezibekwe ekamelweni elimnyama azinawo umbala nhlobo. Ngakho-ke, ukukhanya kuyisici esibaluleke kakhulu sokunquma ukuthi uyawubona yini umbala.

Ithini inkomba yokunikeza umbala (CRI)?

Incazelo elula ikhono lomthombo wokukhanya ukuze libonise ngokunembile zonke izinhlobo zefrikhwensi ezingaba khona ze-spectrum ethile uma kuqhathaniswa nezinga lokushisa lombala. Ibanga layo elikahle lokulinganisa lingu-1-100. Ukukhanya kwemini yemvelo kune-CRI efika ku-100, kuyilapho izibani ze-LED zamanje zisukela ku-75 kuya ku-90. Ngokuvamile, ama-CRI aphezulu abiza kakhulu.

Lapho i-CRI iphansi, iyancipha ukunemba kokukhiqizwa kombala. Umthombo wokukhanya one-radiator eshisayo uvame ukuba ne-CRI engaba ngu-100 ngoba yonke imibala ku-spectrum ye-CRI iboniswa ngokulinganayo ngendlela yayo. Isibonelo, ungabona ukuthi ama-apula anombala we-"burgundy" elangeni, futhi azoba nombala "opinki omnyama" ngaphansi kwezibani eziphansi ze-CRI. Kuyini ukubaluleka? Ngezikhathi ezikhethekile ezifana namagalari namamnyuziyamu, ukukhanya kudinga i-CRI efika kokungu-95+ ukuvumela izivakashi ukuthi zibone imibala “yangempela”.

Kuyini izinga lokushisa lombala?

Ichazwa njengendlela elula yokuchaza izici ezihlukene zombala wokukhanya; ihlanganisa amathoni afudumele (amathoni aphuzi) namathoni apholile (amathoni aluhlaza okwesibhakabhaka) alinganiswa ngamadigri e-Kelvin.

Ukuphakama kwedigri ye-Kelvin, izinga lokushisa lombala limhlophe. Nokho, ukukhanya okumhlophe kuzokhanya kunoKelvin ophansi.

Ngakho-ke, i-CRI ithinta umbala wento esiyibonayo, futhi izinga lokushisa lombala liwumbala wokukhanya okukhishwayo. Ziyimingcele ehluke ngokuphelele echaza imvelo yomthombo wokukhanya.

Indlela yokusebenzisa ukukhanya ezindaweni zokuhweba ?

1. Indawo yokupaka

Izibani eziningi endaweni yokupaka zinezinga lokushisa lombala elingu-2700K kanye no-80-CRI oshayela endaweni yokupaka, futhi ukukhanya okwengeziwe kulungele wonke umuntu. Iphephe kakhudlwana kubashayeli nabahamba ngezinyawo, hhayi nje ukukhanya okufiphele okungajwayelekile, okungaholela ezingozini ngisho nokweba. Okubaluleke kakhulu ekukhanyisweni kwendawo yokupaka ukuthi kufanele kukhanyiswe kahle ebusuku ukuze kuncishiswe isibalo sezingozi nobugebengu obenzekayo. Izindawo eziningi zokupaka zisebenzisa ukukhanya okungu-2700 kuya ku-3500K (okufudumele) kanye no-65 kuya ku-80 CRI.

Ezinye zezinto abantu okufanele bazikhumbule mayelana namaqiniso okungcola kokukhanya. Kusukela ekufudukeni kwezilwane ezihlukahlukene zasemhlabeni kuya ekufudukeni kwezinyoni ezinkulu, ukungcoliswa kokukhanya kuthinta imvelo ngezindlela eziningi ezahlukene. Lezi zidalwa ziye zaba nomthelela omkhulu, ikakhulukazi ezimbi, ngakho-ke zibeka usongo ebukhoneni bazo. Abantu nabo bathinteka ngokuqondile noma ngokungaqondile. Izigqi ze-circadian zezinye izilwane nazo zibe nezinguquko ezinkulu. Ngakho-ke, ukunakekelwa kufanele kuthathwe lapho kukhethwa ukukhanya okulungile.

2. Inkundla yebhola

Izinkundla zebhola kufanele zisebenzise amazinga okushisa aphezulu anombala kanye namalambu e-CRI. Manje, ibhola lezinyawo lidume kakhulu kunangaphambili. Ngakho-ke, ukuze umdlalo udlale kahle ngokwanele, kufanele uvezwe ngokugcwele nangendlela efanele enkundleni. Ngokusobala, izibani eziphezulu ze-CRI ngesikhathi sokusakazwa nemidlalo efakiwe zizoba ngcono futhi zikhanye kunokujwayelekile. Kodwa-ke, ukukhanya kuyo yonke eminye imidlalo kufanele kwanele ukudlala umdlalo ngokuphelele. Amehlo kumele abe nokufana nokunethezeka okubonakalayo, ikakhulukazi emidlalweni lapho indawo yokuhlala yangempela ikhona.
