Zithini imibala ekhanyayo yethotshi yangaphandle ekhanyayo?

Ngaba uyazi umbala okhanyayo wengaphandleiitotshiAbantu abadla ngokuba ngaphandle baya kulungiselela ithotshi okanye ephathekayoisibane sentlokoNangona ingabonakali kangako, njengoko ubusuku buqala, olu hlobo lwento lunokuthatha imisebenzi ebalulekileyo. Nangona kunjalo, iitotshi zinemilinganiselo eyahlukeneyo yokuvavanya kunye nokusetyenziswa kwazo. Kule meko, abantu banokunganikeli ngqalelo ingako. Okulandelayo, ngokwembono yombala wokukhanya kwetotshi, ndiza kwabelana nani ngokusetyenziswa kweetotshi zemibala eyahlukeneyo ngaphandle. Isenokungabi luncedo, kodwa kulungile ukwandisa intsimi yombono kwimeko yengxakeko!

ukukhanya okumhlophe

Intetho yokuqala malunga nokukhanya okumhlophe okudumileyo. Ukuthandwa kokukhanya okumhlophe kwaqala ngokusetyenziswa ngokubanzi kwe-LED ezimhlophe kwiitotshi kwiminyaka yakutshanje. Ukukhanya okumhlophe kusondele elangeni, kwaye ukukhanya okumhlophe ebumnyameni kuhambelana namava okubona amehlo ethu, ngoko ke akuthathi xesha ukuba amehlo azivumelanise, kwaye kufanele kube lolona kukhanya lombala likhululekileyo emehlweni. Ngaphezu koko, ukukhanya okumhlophe kuphezulu kunezinye izibane zombala ngokubhekiselele ekukhanyeni nasekushiseni kombala, okunika abantu imvakalelo eqaqambileyo enamandla. Ke ngoko, kwimisebenzi yangaphandle, ukukhanya okumhlophe kusetyenziswa kakhulu ekunyukeni intaba ebusuku nasekukhanyiseni iinkampu.

ukukhanya okutyheli

Ukukhanya okumthubi okukhankanyiweyo apha akusilo ukukhanya okumthubi okukhutshwa zizibane zemveli ezisebenzisa iibhalbhu ezikhanyayo. Ngokwenyani, ukukhanya okukhutshwa zizibane ezikhanyayo kukwaluhlobo lokukhanya okumhlophe, kodwa kutyheli okufudumeleyo ngenxa yobushushu obuphantsi bombala. Ukukhanya okumhlophe ngumxube obomvu, orenji, otyheli, oluhlaza, oluhlaza okwesibhakabhaka, i-ingot, kunye nomfusa. Ngumbala oxutyiweyo. Ukukhanya okumthubi apha ngumbala omnye otyheli ngaphandle kokuxuba. Ukukhanya ngokuyintloko liza le-electromagnetic lobude obuthile. Xa iza le-electromagnetic lisasazeka emoyeni, lineendlela ezintlanu: imitha ethe ngqo, ukubonakalisa, ukudlulisa, ukurhawuzelela, kunye nokusasazeka. Ngenxa yobude balo obuthile, ukukhanya okumthubi akuguquki kakhulu kwaye kusasazeka kuyo yonke imitha ebonakalayo. Oko kukuthi, ukukhanya okumthubi kunokungeneka okunamandla, kwaye phantsi kweemeko ezifanayo, ukukhanya okumthubi kuhamba kude kunokukhanya okubonakalayo. Akunzima ukuchaza ukuba kutheni izibane zendlela zisebenzisa ukukhanya okumthubi kwaye izibane zemoto zisebenzisa ukukhanya okumthubi? Indawo yangaphandle ebusuku idla ngokuhamba nomphunga wamanzi kunye nenkungu. Kwimeko enjalo, iza le-electromagneticigqibelele.

isibane esibomvu

Ukukhanya okubomvu kukwayindlela yokukhanya enemibala esetyenziswa kakhulu ziingcali zangaphandle, ingakumbi kumazwe aseYurophu naseMelika. Imidlalo yokuzingela ithandwa kumazwe amaninzi aseYurophu naseMelika, kwayeiitotshi ezibomvu zithandwa kakhulu ngabantu baseYurophu naseMelika abathanda ukuzingela. I-retina yomntu inezicubu ezimbini ezibona ukukhanya: iiseli zekhoni kunye neeseli zentonga. Iiseli zekhoni zahlula imibala, kwaye iiseli zentonga zahlula imilo. Isizathu sokuba abantu bakwazi ukubona umbala kungenxa yeeseli zekhoni kwi-retina. Izilwanyana ezininzi zineentonga kuphela okanye iikhoni ezimbalwa, nto leyo ebangela ukuba zingabi namvakalelo kumbala okanye zingabi nambono wombala. Uninzi lwamaxhoba aphantsi kweemipu zabazingeli baseYurophu naseMelika lolu hlobo lwesilwanyana, olungenamvakalelo ngakumbi kukukhanya okubomvu. Xa bezingela ebusuku, banokusebenzisa izibane ezibomvu ngokungakhathali ukuze batshabalalise ixhoba ngaphandle kokuba nabani na aqaphele oko, nto leyo ephucula kakhulu ukusebenza kakuhle kokuzingela.

Abathandi basekhaya abanamava okuzingela, kodwa ukukhanya okubomvu kusengumbala wokukhanya oluncedo kakhulu kwimisebenzi yangaphandle. Amehlo ayakwazi ukuzivumelanisa nezimo – xa umbala wokukhanya utshintsha, amehlo adinga inkqubo yokuzivumelanisa nezimo kunye nokulungiswa ukuze avumelane nezimo. Kukho iintlobo ezimbini zokuzivumelanisa nezimo: ukuzivumelanisa nezimo ezimnyama kunye nokuzivumelanisa nezimo. Ukuzivumelanisa nezimo ezimnyama yinkqubo esuka ekukhanyeni iye ebumnyameni, ethatha ixesha elide; ukuzivumelanisa nezimo ezimnyama yinkqubo esuka ebumnyameni iye ekukhanyeni, ethatha ixesha elifutshane. Xa sisebenzisa ithotshi emhlophe kwimisebenzi yangaphandle, xa umgca wokubona utshintsha ukusuka kwindawo ekhanyayo ukuya kwindawo emnyama, ungowokuzivumelanisa nezimo ezimnyama, othatha ixesha elide kwaye uya kubangela “ubumfama” bexesha elifutshane, ngelixa ukukhanya okubomvu kuthatha ixesha elifutshane ukuzivumelanisa nezimo ezimnyama, Kuyayiphepha ingxaki “yobumfama” bexesha elifutshane, okusivumela ukuba siphathe amehlo ethu ngcono kwaye sigcine umbono ongcono ebusuku xa sisebenza ebusuku.

isibane esiluhlaza

Uninzi lwee-LED ezikhanyayo ezimhlophe zivelisa ukukhanya okumhlophe ngokukhanyisa umgubo we-phosphor ngee-LED ezikhanyayo eziluhlaza okwesibhakabhaka, ngoko ke ukukhanya okumhlophe kwee-LED kuqulethe izinto ezininzi ezikhanyayo eziluhlaza okwesibhakabhaka. Ngenxa yesantya esiphezulu sokurhawuzelelwa kunye nesantya sokusasazeka kokukhanya okuluhlaza okwesibhakabhaka xa kudlula emoyeni, kudla ngokuhamba umgama omde, oko kukuthi, ukungena akukuhle, nto leyo enokuchaza isizathu sokuba ukungena kokukhanya okumhlophe kwe-LED kubuthathaka. Sekunjalo, i-Blu-ray inesakhono sayo esikhethekileyo. Amabala egazi lezilwanyana akhanya kancinci phantsi kokukhanya okuluhlaza okwesibhakabhaka. Besebenzisa olu phawu lokukhanya okuluhlaza okwesibhakabhaka, abathandi bokuzingela baseYurophu naseMelika basebenzisa iitotshi ezikhanyayo eziluhlaza okwesibhakabhaka ukulandelela igazi lexhoba elonzakeleyo, ukuze ekugqibeleni baqokelele ixhoba.
