Ungawuthola kanjani cishe umjikelezo okhanyayo wesibani ngokukhanya kwephuzu?

Ungawuthola kanjani cishe umjikelezo okhanyayo wesibani ngokukhanya kwephuzu?

Izolo, uLiu ungibuze umbuzo: isibani sama-watt angu-6, imitha yokukhanyisa engu-1900Lx, bese kuthi ukukhanya okukhanyayo kube ama-lumens amancane nge-watt ngayinye? Lokhu kwakunzima, kodwa ngamnika impendulo, futhi kwakungeyona impendulo efanele ngempela, kodwa ukutholwa kwayo kwakuthakazelisa ngandlela thile.

Manje ake sixoxe ngendlela yokuyithola.

Njengoba sonke sazi, ifomula elula yokubala ukukhanya kwamaphuzu yile:

Ukukhanya kwephuzu le-E —

I — Ukukhanya okuphezulu kakhulu

h – Ibanga eliphakathi kwesibani nendawo yokubala

Ngale fomula engenhla, singathola ukukhanya okuphezulu kwesibani ngaphansi kokucabangela ukuthi isibani sikhanyiswa ngokuqondile endaweni yokubala. Njengoba kushiwo ezimweni ezingenhla, ukukhanya kumitha eli-1 kungu-1900lx, khona-ke ukukhanya okuphezulu kungabalwa kube ngu-1900cd.

Njengoba ukukhanya kunamandla amakhulu, sisantula esinye sezimo ezibaluleke kakhulu, okungukuthi, ijika lokusabalalisa ukukhanya, ngakho-ke ngibuze i-Angle ye-beam yejika lokusabalalisa ukukhanya, futhi ngasebenzisa ezinye izindlela zokuthola ijika lokusabalalisa ukukhanya eline-Angle efanayo ye-beam. Yiqiniso, kunezinhlobo eziningi zamajika okusabalalisa ukukhanya angu-24°, futhi kungenzeka ukuthi amajika abe made, abe mancane futhi akhuluphele, futhi ngifuna ijika elingu-24° ​​eliphelele kakhulu.

Umfanekiso: Ijika lokusabalalisa ukukhanya ku-beam I-engeli engu-24°

Uma sesitholile, sivula ijika lokusabalalisa ukukhanya nge-notepad bese sithola ingxenye yenani lokukhanya.

Umfanekiso: Inani lokukhanya okukhulu kwejika lokusabalalisa ukukhanya

Inani lokuqina kokukhanya likopishwa ku-EXCEL, bese ifomula isetshenziswa ukubala amanye amanani okuqina kokukhanya lapho inani lokuqina kokukhanya okuphezulu lingu-1900.

Umfanekiso: Ukusebenzisa i-EXCEL ukubala amanye amanani okukhanya lapho ukuqina kokukhanya okuphezulu kungu-1900cd

Ngale ndlela, sithola wonke amanani okukhanya okulungisiwe, bese sibuyisela amanani okukhanya okulungisiwe ku-Notepad.

Umfanekiso: Faka esikhundleni inani lokukhanya kwasekuqaleni ku-notepad ngenani lokukhanya okulungisiwe

Sesiqedile, sinefayela elisha lokusabalalisa ukukhanya, sizongenisa leli fayela lokusabalalisa ukukhanya ku-DIALux, singathola ukukhanya kwesibani sonke.

Umfanekiso: Ukukhanya okuphelele okungu-369lm

Ngale mphumela, ake siqinisekise ukuthi ukukhanya kwalesi sibani kumitha eli-1 akusikho i-1900lx.

Umfanekiso: Ukukhanya kwephuzu kumitha eli-1 kungu-1900lx ngokusho komdwebo wekhoni

Kulungile, okungenhla yinqubo yonke yokuthola ulwazi, akuyona eyinkimbinkimbi kakhulu, vele unikeze umbono, awukwazi ukuba nembambo kakhulu, ngoba phakathi nendawo, kungakhathaliseki ukuthi ukuthola ukukhanya noma ukuthola ukusatshalaliswa kokukhanya, akunakuba nembambo engu-100%. Ukuze nje unike wonke umuntu ikhono lokulinganisa.
