Isebenza kakuhle kangakanani i-LED?
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.
Enye into enegalelo ekusebenzeni kokukhanyisa kwe-LED kubomi bayo benkonzo ende. Iibhalbhu ze-LED zihlala ixesha elide ngokuphindwe ka-25 kuneebhalbhu ze-incandescent zemveli kunye namaxesha ali-10 ubude kunee-fluorescent. Oku kuthetha ukuba ukukhanya kwe-LED akugcini nje ukugcina amandla, kodwa kunciphisa ukuphindaphinda kokutshintshwa kwebhalbhu yokukhanya, ngaloo ndlela kuncitshiswe inkunkuma kunye neendleko zokuyigcina. Iibhalbhu ze-LED zityala ixesha elide kulwakhiwo lwazo oluqinileyo, olubavumela ukuba bamelane nomothuko, ukungcangcazela, kunye namaqondo obushushu agqithisileyo, nto leyo ezenza ukuba zibe lukhetho oluzinzileyo noluthembekileyo lokukhanyisa.
Itekhnoloji ye-LED iphumelele kakhulu ngokubhekiselele ekuphumeni kokukhanya. Iibhalbhu ze-LED ziyakwazi ukuvelisa ukukhanya okuphezulu zisebenzisa amandla amancinci, ziqinisekisa ukuba uninzi lombane eziwusebenzisayo ziguqulwa zibe kukukhanya okubonakalayo. Oku kwahluke kakhulu ekukhanyeni kwendabuko, apho uninzi lwamandla lulahleka njengobushushu. Ke ngoko, ukukhanya kwe-LED akuboneleli nje ukukhanya okungcono kodwa kunceda ekudaleni indawo epholileyo kunye nekhululekile ngakumbi, ngakumbi kwiindawo ezivaliweyo.
Ukongeza ekusebenzeni kakuhle kwamandla, itekhnoloji ye-LED inika ezinye iingenelo ezinegalelo ekusebenzeni kakuhle ngokubanzi. Umzekelo, iibhalbhu ze-LED zikhanya ngoko nangoko, oku kuthetha ukuba zifikelela ekuqaqambe kakhulu kwangoko xa zilayitiwe, ngokungafaniyo nezinye iintlobo zokukhanyisa ezifuna ixesha lokufudumala. Oku kwenza ukukhanya kwe-LED ngokukhethekileyo kulunge ngakumbi kwizicelo ezifuna ukukhanya okukhawulezileyo nokungaguquguqukiyo, okufana nezibane zendlela, ukukhanya okungxamisekileyo kunye nezibane zangaphandle ezishukumayo.
Enye inzuzo yeteknoloji ye-LED kukulawulwa kwayo okugqwesileyo. Iibhalbhu ze-LED zinokufiphala kwaye zikhanyise ngokuchanekileyo, zivumela abasebenzisi ukuba balungelelanise ukuphuma kokukhanya ukuze kuhambelane neemfuno zabo ezithile. Eli nqanaba lokulawula aligcini nje ukwandisa i-ambience kunye nokusebenza kwendawo, kodwa ligcina amandla ngokunciphisa ukusetyenziswa kwamandla ngokubanzi kwenkqubo yokukhanyisa.
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.
