Ngaba izibane ze-LED ziwusebenzisa okanye ziwugcine umbane?
Izibane ze-LED ziwonga amandla.
Izibane ze-LED zenziwe ngemithombo yokukhanya egcina amandla. Xa kuthelekiswa nemithombo yokukhanya yemveli, imichilo yokukhanya ye-LED ineenzuzo ezinkulu ekusebenziseni amandla. Ngokukodwa, izibane ze-LED zinganciphisa ukusetyenziswa kwamandla malunga ne-80% xa kuthelekiswa nezibane ze-incandescent ezinokukhanya okufanayo, kunye ne-40% xa kuthelekiswa nezibane zokulondoloza amandla. Ukongeza, iintambo zokukhanya kwe-LED zineempawu zemibala ekhanyayo eguquguqukayo, ukuncipha, kunye nokutshintsha kombala olawulekayo, ezinokubonelela ngeziphumo ezibonakalayo ezinemibala. Kwangaxeshanye, basebenzisa i-low-voltage power supply, kwaye umbane wombane uphakathi kwe-DC 3-24V, kuxhomekeke kwimveliso. Ngokwahlukileyo, oku kwenza ukuba izibane ze-LED zikhanyise ngamandla ngelixa zibonelela ngezibane ezikumgangatho ophezulu.
Nangona kukho imbono yokuba izibane ze-LED aziwongi amandla, oku kungenxa yokuba iingcamango zokulondoloza amandla kunye nokugcina amandla zididekile. Enyanisweni, izibane ze-LED zisebenzisa amandla amancinci kunemithombo yokukhanya yendabuko njengezibane ze-incandescent ekukhanyeni okufanayo kwaye zigcina amandla amaninzi. Nangona kunjalo, ukuba kuthelekiswa phantsi kwamandla afanayo, ukukhanya kwezibane ze-LED kuphezulu, oku kuthetha ukuba ukuze kuphunyezwe umphumo ofanayo wokukhanya, izibane eziphezulu ze-LED zingadinga ukusetyenziswa, ngaloo ndlela ukwandisa ukusetyenziswa kwamandla. Ukongezelela, ukunyuka kwemfuno yokukhanya kwimizi yanamhlanje kubangele ukwanda kwamandla kunye nobuninzi bezibane, okusisizathu sokunyuka kwamatyala ombane.
Ukushwankathela, nangona izibane zokukhanya ze-LED ngokwazo zigcina amandla, ekusebenziseni ngokwenene, ukusetyenziswa kwamandla kuchaphazeleka kwizinto ezininzi, kubandakanywa noyilo lwesibane, ukusetyenziswa rhoqo, kunye nemfuno yomsebenzisi yokukhanya.Ngoko ke, kuphela ngokukhetha ngokufanelekileyo kunye ngokusebenzisa izibane asinakukwazi ukuhlangabezana neemfuno zokukhanyisa kuphela, kodwa sifezekise iziphumo zokonga amandla.
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.
