Imiphumo yemibala eyahlukeneyo yokukhanya ebantwini
Izibane ezahlukeneyo zineziphumo ezahlukeneyo ebantwini, njengeziphumo ezibonakalayo, iziphumo zengqondo, izingqisho zebhayoloji, iziphumo zempilo, iziphumo zokuziphatha, kunye neemvakalelo zendawo.
- Iziphumo ezibonakalayo: Izibane ezahlukeneyo zinokuzisa amava ahlukeneyo okubonwayo ebantwini. Izibane ezikhanyayo zinokunyusa ukuqaphela kunye nokugxila kwabantu, ngelixa izibane ezithambileyo zinokwenza umoya ofudumele kunye nokuphumla.
- Impembelelo yengqondo: Umbala kunye nokukhanya kokukhanya kunempembelelo ngqo kwiimvakalelo zabantu kunye nesimo sengqondo. Ngokomzekelo, ukukhanya okuluhlaza okwesibhakabhaka kucingelwa ukwandisa ukugxila kunye nokuzola, ngelixa ukukhanya okubomvu kunokunyusa amandla kunye nemincili.
- Isingqisho sebhayoloji: Ukukhanya kunokuchaphazela isingqisho sebhayoloji yabantu, ngakumbi ukulawulwa kokulala kunye nokuvuka. Imithombo yokukhanya eluhlaza okwesibhakabhaka, njengaleyo ikhutshwa zizixhobo zombane, ithintela inkqubo yokuvelisa imelatonin, egcina abantu bephaphile. Ngokwahlukileyo, imithombo yokukhanya ethambileyo emthubi inokunceda ukukhuthaza ukulala.
- Iziphumo zempilo: Ukushisa kombala wokukhanya (iqondo lokufudumala okanye ukubanda kombala) kunokuchaphazela ukunethezeka okubonakalayo kwabantu kunye nempilo. Izibane ezinobushushu obuphezulu bemibala, njengokukhanya okumhlophe, zicingelwa ukuba zandisa ukuphaphama, kodwa ukuvezwa kwexesha elide kunokuba nemiphumo emibi emehlweni. Ngokwahlukileyo koko, ukukhanya okunobushushu obunombala osezantsi (ofana nokukhanya okutyheli) kunokwenza abantu bazive bekhululekile kwaye bekhululekile.
- Impembelelo yokuziphatha: Ukuqaqamba kunye nokulungelelaniswa kokukhanya nako kunokuchaphazela ukuziphatha kwabantu. Izibane ezikhanyayo zinokonyusa ukuphapha kwabantu kunye nemveliso, ngelixa izibane ezikhanyayo zinokunceda ukudala umoya wokuphumla kunye nowothando.
- Amava omhlaba: Uyilo lokukhanyisa olwahlukileyo lunokutshintsha imbono yabantu kunye namava ovakalelo esithubeni. Umzekelo, ukusebenzisa izibane ezifudumeleyo kunokwenza igumbi libukeke lamkelekile kwaye lipholile, ngelixa ukukhanya okupholileyo kunokunika ukuziva okutsha kunye nesimanje.
Ngokubanzi, uyilo lokukhanya olwahlukileyo lunokuchaphazela abantu ngeziphumo ezibonakalayo, iziphumo zengqondo, izingqisho zebhayoloji, iimeko zempilo, iziphumo zokuziphatha kunye neemvakalelo zendawo. Ngoko ke, xa ukhetha kunye nokuyila izibane, iimeko ezithile kunye neenjongo kufuneka ziqwalaselwe ukufezekisa umphumo oyifunayo.
Itekhnoloji ye-LED iguqule indlela esikhanyisa ngayo amakhaya ethu kunye namashishini. Akugcini nje ukuzisa amandla ombane ekukhanyeni, kukwaphucula umgangatho wokukhanya, okwenza kube lula ukulungelelanisa kwizicwangciso ezahlukeneyo. I-LED imele i-light-emitting diode, isixhobo se-semiconductor esikhupha ukukhanya xa umbane udlula kuyo. Itekhnoloji ye-LED isebenze ngakumbi kunezibane zendabuko ze-incandescent kunye nezibane ze-fluorescent. Kodwa zisebenza kangakanani ii-LEDs?
Esinye sezibonakaliso eziphambili zokukhanyisa ukukhanya kukusetyenziswa kwamandla. Itekhnoloji ye-LED iyaziwa ngokusetyenziswa kwayo okuphantsi kwamandla, okwenza kube lukhetho oludumileyo lokukhanyisa indawo yokuhlala kunye nezorhwebo. Enyanisweni, iibhalbhu ze-LED zonga ukuya kutsho kuma-80% ngaphezulu kwamandla kuneebhalbhu ze-incandescent zemveli kwaye malunga ne-20-30% ngaphezulu kunezibane ze-fluorescent. Ukuncitshiswa kokusetyenziswa kwamandla akugcini nje ukuthoba amatyala ombane wabathengi kodwa kunceda kakhulu ukunciphisa ukukhutshwa kwekhabhoni, okwenza iteknoloji ye-LED ibe yindlela yokukhanyisa indalo.
Kukho konke, iteknoloji ye-LED iphumelele kakhulu ngokubhekiselele ekusebenziseni amandla, ixesha elide, ukuphuma kokukhanya kunye nokulawula. Ukusetyenziswa kwamandla aphantsi, ubomi obude, ukukhanya okuphezulu kunye nokusebenza ngokukhawuleza kwenza kube lukhetho oluhle kakhulu lokukhanyisa xa kuthelekiswa nezibane zendabuko kunye nezibane ze-fluorescent. Njengoko imfuno yokonga umbane kunye nezisombululo zokukhanya ezihambelana nokusingqongileyo ziqhubeka zikhula, iteknoloji ye-LED kulindeleke ukuba idlale indima ebalulekileyo ekubunjweni kwekamva lokukhanya.
