Mwenje yekuvhiya isina mumvuri maturusi ekuvhenekesa akakosha panguva yekuvhiya. Kune michina inokwanisa, mamwe akakosha maratidziro ekuita anofanirwa kusangana nezviyero kuitira kuzadzisa zvatinoda zvekushandisa.
Chekutanga, zvakakosha kuve nechiedza chakakwana. Kuvhenekera kwerambi rekuvhiya risina mumvuri rinogona kusvika pamusoro pe150000 LUX, iri padyo nekupenya pasi pezuva pamazuva ezuva muzhizha. Nekudaro, iyo chaiyo yekuvhenekera inoshandiswa kazhinji yakakodzera pakati pe40000 ne100000 LUX. Kana yakanyanya kupenya, inokanganisa chiono. Marambi ekuvhiya asina mumvuri anofanirwa kupa kuvhenekera kwakakwana ukuwo uchidzivirira kupenya kubva padanda rezviridzwa zvekuvhiya. Kupenya kunogonawo kukanganisa maonero uye maonero, zvichiita nyore nyore kuneta kwemaziso kune vanachiremba uye kudzivisa maitiro ekuvhiya. Kuvhenekera kwemwenje wekuvhiya usina mumvuri haufanire kusiyana zvakanyanya kubva kune yakajairika mwenje mukamuri yekuvhiya. Mimwe mipimo yeruvheneko inotaura kuti mwenje wose unofanira kuva chikamu chimwe mugumi chechiedza chenzvimbo. Kuvhenekera kwese kwekamuri yekushandisa kunofanirwa kunge kuri pamusoro pe1000LUX.
Kechipiri, iyo isina mumvuri dhigirii yekuvhiya isina mwenje mwenje inofanira kunge yakakwira, inova chinhu chakakosha uye chiratidziro chekushanda kwerambi rekuvhiya risina mumvuri. Chero mumvuri wakaumbwa mukati memunda wekuvhiya wekuona uchatadzisa chiremba kutarisa, kutonga, uye kuvhiyiwa. Chiedza chakanaka chekuvhiya chisina mumvuri hachifanirwe kungopa kuvhenekera kwakakwana, asi zvakare kuve nekukwirira kusina mumvuri kusimba kuti ive nechokwadi chekuti pamusoro uye yakadzika matishu enzvimbo yekuvhiya yekuona ine imwe nhanho yekupenya.
Nekuda kwekupararira kwechiedza, kana chiedza chichivhenekera pachinhu chisina kujeka, mumvuri unoumba kuseri kwechinhu. Mimvuri inosiyana munzvimbo dzakasiyana uye panguva dzakasiyana. Semuenzaniso, mumvuri wemunhu mumwe chete muchiedza chezuva wakareba mangwanani uye mupfupi masikati.
Nokucherechedza, tinogona kuona kuti mumvuri wechinhu chiri pasi pechiedza chemagetsi kunyanya kusviba pakati uye zvishoma kudzika kumativi ose. Chikamu chakasviba zvikuru chiri pakati pemumvuri chinonzi umbra, uye chikamu cherima chakaukomberedza chinonzi penumbra. Kuitika kwezviitiko izvi kune hukama zvakanyanya nemusimboti wemutsara wekuparadzira chiedza. Chakavanzika chinogona kuziviswa kuburikidza nekuedza kunotevera.
Isu tinoisa kapu ye opaque patafura yakatwasuka uye tinobatidza kenduru padivi payo, tichikanda mumvuri wakajeka kuseri kwekapu. Kana makenduru maviri akabatidzwa padivi pekapu, mimvuri miviri inoturikidzana asi isingadhumani inogadzirwa. Chikamu chinopindirana chemimvuri miviri chinenge chakasviba zvachose, saka chinenge chakasviba zvachose. Iyi ndiyo umbra; Nzvimbo chete iri pedyo nemumvuri uyu inogona kuvhenekerwa nekenduru ndiyo hafu yerima hafu mumvuri. Kana matatu kana mana kana kupfuura makenduru akabatidzwa, umbra ichaderera zvishoma nezvishoma, uye penumbra ichaonekwa muzvikamu zvakawanda uye zvishoma nezvishoma inosviba.
Izvozvi zvinoshanda kune zvinhu zvinogona kuburitsa mimvuri inoumbwa neumbra uye penumbra pasi pechiedza chemagetsi. Rambi remagetsi rinoburitsa mwenje kubva kune yakakombama filament, uye emission poindi haina kugumira pane imwe chete. Chiedza chinobudiswa kubva pane imwe nzvimbo chinovharwa nechinhu, nepo chiedza chinobudiswa kubva kune dzimwe nzvimbo chingave chisingaiti kuvharwa. Zviripachena, iyo yakakura nzvimbo yemuviri unopenya, iyo idiki umbra. Kana tikatungidza denderedzwa remakenduru kutenderedza kapu yataurwa pamusoro apa, umbra ichanyangarika uye penumbra ichave yapera simba zvekuti haigone kuonekwa.
