Kuwala metering: Chiphunzitsochi ndi Tsatani

Chiwalitsiro - ichi chikuperekedwa thupi, yodziwika ndi chiŵerengero cha kuwala kamwazi chochitika padziko m'dera ake. Iko anamvetsa kuti padziko ndege ayenera kukhala perpendicular kwa olamulira kuwala akulowera.

Kuwonjezera mfundo za ukhondo mwachindunji anthu zayamba kuwala muyeso ntchito ulimi nyama kupanga yoyenera microclimate Kupititsa patsogolo maphunziro, mu kuswana Aquarium nsomba ndi zomera kulima zomera potted, pofotokoza makhalidwe zida zithunzi video, kuphatikizapo kanema kamera anaziika.

magwero zounikira

Amadziwika kuti pali zachilengedwe ndi yokumba kuunikira. Iwo amalenga yoyenera kuwala kochokera: amatanthauza zachilengedwe kuwala yozungulira za mlengalenga, ndithudi, dzuwa ndi kuwala konyezimiritsa mwezi. magwero yokumba - nyali osiyana (nyali incandescent, kumaliseche nyali, fulorosenti), zowonetsera TV ndi makompyuta.

N'chifukwa chiyani tiyenera kuziyeza illuminance

Kuyatsa - mmodzi wa zizindikiro thanzi zofunika kwambiri, potsata mwachindunji thanzi la munthu. kuwala muyeso - ndondomeko zili m'gulu SanPin (malamulo mwaukhondo ndi malamulo) mosamala anapanga pa ndime kuntchito ndi miyezo ya kaperekedwe ka phokoso, kugwedera, fumbi ndi kuipitsidwa mpweya.

Madokotala amanena kuti kupanda Kuphunzira kumatanthauza kuchepetsa acuity zithunzi, kutopa, yafupika ndende ndi akukhudzidwira zokolola akhoza ngakhale kuchita ngozi. The akusowa nyama ndi mbalame chiwalitsiro chimachititsa matenda kukula, chitukuko cha zoipa ya misa ya thupi, imfa ya zokolola (kwa ziweto) ndi luso kubereka.

Kodi nanga mayunitsi chimaonekera, kuchuluka lino nde

Kuwala metering chipangizo imagwiridwa wotchedwa mita kuwala, kunyamulika chipangizo chimene chiri ngati photometer a. Modern telefoni zam'manja mkulu-mapeto amaphatikiza Zosefera. Unit chiwalitsiro muyeso mu dongosolo lonse mayunitsi (SI) - Maapatimenti, umene ndi chiŵerengero cha mita lalikulu 1 lumen m'dera pamwamba. The lumens anayeza kuwala kamwazi kuchuluka. Machitidwe American ndi British ntchito ngati chingwe choyezera wagawo illuminance monga lumens pa phazi lalikulu, phazi candela (digiri zounikira pa kuwala gwero mphamvu ya 1 candela, spaced 1 phazi limodzi kuchokera pamwamba).

Kodi muyeso kuwala? Izi zachitika ntchito mita kuwala, mita ayenera kukhala wotsiriza mu malo yopingasa, kuziyika izo mu mfundo Napempha kwa chipindacho. Pakuti nyumba ndi maofesi ziweto, pali wapadera zolamulidzwazo potsata mfundo boma mu miyeso malo kulamulira. Gwiritsani ntchito malangizo kwa chipangizo Pamene ntchito nozzle ayenera kuwaganizira attenuation chinthu chimene chifukwa ndi kuchuluka. Ndiye, mitunduyi zosiyanasiyana mopitirira osachepera, pafupifupi, pazipita chiwalitsiro, komanso chiŵerengero cha kuwala.
