Uma umndeni unomfundi oya esikoleni, isici esibaluleke kakhulu ekamelweni lakhe, ngaphandle kwedeskithophu, isibani setafula. Nguye owenza ukukhanyisa kukwanele ukuthi ingane ikwazi ukwenza umsebenzi wesikole ngaphandle kokulimaza umbono nomumo . Kudingeka isibani setafula kumfundi, nakumuntu osebenzayo, kungakhathaliseki ukuthi ummeleli wobuciko bokudala noma i-plankton yehhovisi. Ngakho, ngaphandle kwesibani sokusebenza kwedeskithophu asikwazi ukwenza.
Izidingo zesibani sedeskithophu
Noma yiliphi i-ophthalmologist lizokutshela ngokuqiniseka ukuthi indawo yokusebenzela ngaphandle kwesibani akufanele ibe khona nhlobo. Ikakhulukazi le mfuneko ibalulekile emzimbeni okhulayo, lapho ukukhanyisa okuncane okungabangela ukungaqondakali kahle . Noma kunjalo, njengebani lesibani, akuzona zonke izibani ozithandayo esitolo.
Kuhle ukuthi ukuphakama kwesibani sokusebenza kufinyelela ku-30-50 cm. Kule ukuphakama, ukukhanya okuvela esitokisini sokukhanya kwesibani kuyokwehla kuwo wonke umsebenzi osebenzayo wetafula. Ngaphezu kwalokho, kwaziwa ukuthi ukukhanya ngokwalo kufanele kwasakazeka, ngoba imisebe yokukhanya ekhanyayo iyathukuthelisa amehlo, yonakalisa amehlo futhi ingabangela izinhloko. Yingakho ochwepheshe batusa ukukhetha isibani sethebula ngesibani sokukhanyisa esenziwe ngesimo se-sphere noma i-cone.
Ngaphezu kwalokho, i-bulb yokukhanya yedivayisi yokukhanyisa kungcono ukukhetha ingenamandla. Okufanelekile, uma amandla ayo avela kusuka ku-40 kuya ku-60, angaphezu kwama-watts angu-100. Ungakhohlwa mayelana nokuzinza komklamo - lokhu kuthinta ukuphepha komsebenzisi futhi, nakanjani, ubuqotho bedivayisi.
Ungakhetha kanjani isibani sedeskithophu?
Ukukhethwa kwanamuhla kwesibani setafula kuqiniswa yizinhlobonhlobo zezinhlobonhlobo ezinikezwe emashalofini nasezindongeni zezitolo. Mhlawumbe, kungase kuqinisekiswe ngokuqiniseka ukuthi manje lo msebenzi wokukhanyisa ungadlala indima yezinto zokuhlobisa kwanoma yiliphi igumbi - indawo yokuhlala noma ihhovisi. Ngakho-ke, isibonelo, ekamelweni labantwana ngokuvamile likhetha izibani zemibala egqamile, ngesibani sesibani ngesimo se-cartoon noma isilwane esihle. Uma igumbi lingumfundi wesikole esiphakeme noma umfundi, thola imodeli emlenzeni oguquguqukayo ozosiza ukuqondisa ukukhanya ngendlela efanele. Imikhiqizo eqinisekisiwe ene-pantograph - uhlelo lensimbi olugcina i-plafond, elikuvumela nokuthi ulawule isiqondiso sokugeleza kokukhanya. Nokho, kulokhu, sincoma ukukhetha imodeli enokwethenjelwa, okwathi ngemuva kwengxenye yonyaka yokusebenza ngeke "ikulandele ukuthi uphile isikhathi eside." Uma ekhaya lakho evame ukuba nezingane ezincane, ngokuphepha nokuphepha kwabo kwedivayisi, lalela isibani setafula ngokuzibophezela okukhethekile etafuleni. Imikhiqizo ethandwa kakhulu i-clamp-clamp, eqinisa ngokucacile le divayisi phezulu kwetafula. Ngaphezu kokuthembeka, lokhu kuqinisa kukuvumela ukuthi ulondoloze amamentimitha amaningi kule ndawo yokusebenzela edingekayo. Itafula liqondiswe etafuleni futhi isibani esinobhanki sisilungisiwe. Kukhona ukukhetha kwesibani sethebula ku-texspin. Ngaphezu kokuzinza, lo modeli ulula ngoba ungasetshenziswa kuphi, hhayi nje etafuleni. Umklamo wayo oguquguqukayo uvumela, futhi, ukuqondisa ukugeleza kokukhanya.
Uma unamathela embonweni wokuthi kukho konke kubalulekile hhayi kuphela ukusebenza nokuthembeka,
