Izinto ezichaphazela isiphumo sokukhanya azibikho ngaphezu kwezi: ukukhanya, ukuqaqamba, unikezelo lombala kunye nokubengezela. ezi zinto zingundoqo kwisiphumo sokukhanya somgangatho ophezulu. Inqanaba lokukhanyisa elifanelekileyo, kuluhlu oluthile lokunyuswa kokukhanya, kunokuphucula umsebenzi obonakalayo.
Ekumiseleni ubungakanani bokukhanya okufunekayo bume obukhanyisiweyo, ubungakanani bento ebonwayo kunye neqondo lokuchasana nokukhanya okungasemva kufuneka kuthathelwe ingqalelo ukuze kuqinisekiswe iimfuno ezisisiseko zokuqinisekisa umbono ngokukhanya okufanayo kunye nokufanelekileyo. Ukukhanyisa kwangaphakathi, akusiyo ukukhanya ngakumbi ngakumbi, utshintsho olufanelekileyo lokukhanyisa lunokuba lusebenza emoyeni wangaphakathi, luphucule incasa yobuhle bomntu.
Malunga nokuyilwa komlinganiselo wokukhanya wangaphakathi:
Ukulingana kokukhanya kwangaphakathi kubhekiselele kumlinganiselo phakathi kweqondo elincinane lokukhanyisa kunye neqondo eliphakathi lokukhanyisa, elingekho ngaphantsi kwe-0.7. Ukukhanya kwendawo engasebenziyo akufanele kube ngaphantsi kwe-1/3 yokukhanya kwendawo yokusebenza. Amaxabiso okukhanya okuphakathi kwezithuba ezimeleneyo azinakwahluka ngaphezu kwamaxesha ama-5
Ukusasazwa kokukhanya kwezenzululwazi
Ukukhanya kubhekiselele kumandla okukhanya kwiyunithi yendawo eqikelelweyo yomgca wendlela yokubona, kwi-cd / ㎡. Imele imbono ecacileyo yokuqaqamba kwento. Ukwabiwa kokukhanya kokukhanya kwangaphakathi kuchongwa ngokusasazwa kokukhanya kunye nomlinganiselo wokubonisa umphezulu.
Kuyilo lokukhanyisa ngaphakathi, kufuneka kuhlawulwe ingqalelo ukuze kuqinisekiswe ukuhanjiswa kokukhanya okufanelekileyo. Ngokubanzi, ukusasazwa okuhluka kakhulu ekukhanyeni kunokonakalisa umbono wabantu, kubangele ilitha elingathandekiyo.
Ngokubanzi, amehlo amkela amanqanaba amathandathu okusasazwa kokukhanya, ngolu hlobo lulandelayo:
Kodwa kwindawo enye, amehlo abantu akakwazi ukufikelela kumanqanaba amathathu. Kukho iinkqubo ezimbini ezahlukeneyo ze-photoreceptor kwiretina yomntu, oko kukuthi umbono oqaqambileyo kunye nombono omnyama.
Iliso lokutshintsha kokukhanya kokutshintsha kwehlabathi langaphandle, liyakwazi ukulungelelanisa ngokufanelekileyo iiseli ze-cone zamehlo kunye neeseli zekholomu, ukuze ube nengqiqo efanelekileyo, le nto ibizwa ngokuba "ukulungiswa kokukhanya".
Kuyilo lokukhanyisa, kufuneka kwakhona sinikele ingqalelo kwimpembelelo yokukhanya kunye nomthunzi wombono, onje ngepaseji yehotele, ludibaniso lokudlula kwindawo yokungena kunye namagumbi eendwendwe, kufuneka kumiselwe ukukhanya okuthambileyo okuphantsi kokukhanyisa, ukuze iindwendwe. zilungele inguqu ebonakalayo.
Kuyilo lweevenkile zorhwebo, kufuneka kwakhona sinikele ingqalelo ukuba zonke izibane zangaphakathi kufuneka zikhanyiswe emini, zombini ukuphepha umphumo wetanki yeentlanzi, kunye nokulungelelanisa ngokufanelekileyo iindwendwe ukuze zivumelane nokukhanya kunye nomthunzi wendawo.
