Metering Khanyisa: Ulwazi Ngokusetshenziswa

Illumination - lokhu ezidlula ngokomzimba, libhekene ratio ukukhanya sigameko ecucuza phezu endaweni yayo. It ngokuba kuqondakala ukuthi indiza ebusweni kufanele perpendicular eksisi ukukhanya ukugeleza.

Ngaphandle amagugu yokuhlanzeka ngqo womuntu nesilinganiso kakhulu ukukhanya elisetshenziswa nemfuyo ngokudala efanele microclimate Ngcono, ngokuzalanisa inhlanzi aquarium izitshalo ukutshala izitshalo potted, ukuchaza izici imishini enezithombe nevidiyo, kuhlanganise ividiyo ikhamera ukubhekwa.

imithombo sokukhanyisa

Kuyaziwa ukuthi kukhona izibani zemvelo kanye yokufakelwa ezaziwayo. Lwenza ukukhanya imithombo efanele: libhekisela zemvelo esizungezile kwesibhakabhaka, yebo, ilanga nokukhanya kubonakala zenyanga. imithombo Artificial - izibani ezahlukene (izibani incandescent, izibani ocucuzayo, Fluorescent), izikrini TV nama-computer.

Kungani sidinga ukukala illuminance

Ukukhanyisa - omunye izinkomba zezempilo ezibaluleke kakhulu, empilweni yomuntu okuyinto kuncike ngokuqondile. nesilinganiso ukukhanya - inqubo likhona SanPin (iziqondiso sanitary kwezinkambiso), wenza ngokucophelela phezu par emsebenzini nge izilinganiso amazinga umsindo, vibration, uthuli negesi ukusilaphazeka.

Odokotela bathi ukuntuleka Ukusabalala kufaka nokuncipha acuity ezibukwayo, ukukhathala, okuhlushwa sinciphile jikelele umkhiqizo kungase kubangele ngisho ingozi. I ukuntula izilwane nezinyoni okukhanyisa obangela ukukhula neziyaluyalu, ukuthuthukiswa kohlelo ezimbi iqoqo mass yomzimba, ukulahlekelwa umkhiqizo (i nemfuyo) futhi ikhono nokuzala.

Kanjani futhi kulokho amayunithi kukalwa, lokhu ubuningi ngokomzimba

Khanyisa idivayisi metering wenziwa ebizwe imitha ukukhanya, idivayisi ephathekayo okuyinto uhlobo a photometer. ephezulu Modern omakhalekhukhwini zazihlanganisa izihlungi. Unit okukhanyisa nesilinganiso ohlelweni lomhlaba wonke amayunithi (SI) - i-suite, okuyinto isilinganiso 1 imitha isikwele inesikhala surface area. I lumens kulinganiswa ukukhanya lemali yokucucuza. I izinhlelo American futhi waseBrithani eziwasebenzisayo enjalo wokulinganisa iyunithi yokulinganisa illuminance njengoba lumens ngayinye unyawo square, unyawo-Candela (idigri ngezibani ukukhanya amandla umthombo 1 Candela, esilinganayo 1 unyawo ebusweni).

Injani nesilinganiso ukukhanya? Lokhu kwenziwa ngokusebenzisa imitha ukukhanya, imitha kumele kube lokugcina evundlile, bawubeke iphuzu oyifunayo egumbini. Ukuze izakhiwo nemfuyo izindawo, kukhona ekhethekile ebekwe amazinga isimo ukulawula indawo izinyathelo. Sebenzisa isiqondiso kudivayisi uma isicelo umlomo wombhobho kumele kubhekwe attenuation isici ngawo yi iyanda. Khona-ke, amafomula ahlukahlukene kubalwa esiphansi, ngokwesilinganiso, ukukhanya esiphezulu, kanye isilinganiso yokukhanya yemvelo.
