Kungani i-LED ibhekwa njengokukhanya kobuchwepheshe bokonga amandla?
Njengoba isikhathi sihamba, abantu baqala ukuqonda ngokujulile ukuchithwa kwamandla okuhlobene nama-bulb okukhanya ajwayelekile. Naphezu kwempumelelo yawo enkulu ekuhlinzekeni ngokukhanya, ama-bulb akhanyayo ahlushwa yizinkinga zokuguqula ingxenye enkulu yamandla ibe ukushisa kunokukhanya, okwaholela ekusebenzeni kahle kwamandla okuphansi kakhulu.
Kulesi sigaba esibalulekile, umsunguli ogama lakhe lingu-Edison waqhubekela phambili ekuphishekeleni ukonga amandla kanye nomoya wokuqamba izinto ezintsha, eqala umsebenzi wokuthuthukisa ukukhanyisa kagesi. Ngemva kokuhlola okuningi, ekugcineni wasungula uhlobo olusha lwesibani sikagesi - isibani sokukhanyisa esikhanyayo. Lo mklamo wathuthukisa kakhulu ukusebenza kahle kokukhanyisa, kodwa wehluleka ukubhekana nenkinga eyisisekelo yokulahlwa kwamandla.
Kodwa-ke, njengoba abantu babebhekene nale nkinga, kwavela ubuchwepheshe be-LED (Light Emitting Diode). Izibani ze-LED zasebenzisa izinto ze-semiconductor ukukhipha ukukhanya, esikhundleni sokushisa izintambo zensimbi ukuze zikhiqize ukukhanya, ngaleyo ndlela zaguqula imboni yokukhanyisa. Izibani ze-LED azizange zinikeze kuphela ukusebenza kahle kwamandla okuphezulu, cishe wonke amandla aguqulwa abe ukukhanya esikhundleni sokushisa, kodwa futhi zazizigqaja ngempilo ende kanye nokukhishwa kokukhanya okucacile, zaba yinto entsha ethandekayo embonini yokukhanyisa.
Ngokukhula okuqhubekayo kanye nokuthandwa kobuchwepheshe be-LED, izibani ze-LED zaqala ukusetshenziswa kabanzi emikhakheni eyahlukene. Kusukela ekukhanyeni kwasekhaya kuya ekukhanyeni kwezentengiselwano, kusukela ezibanini zezimoto kuya ezikrinini zethelevishini, ubuchwepheshe be-LED baletha inguquko embonini yokukhanyisa. Abantu baqaphela kancane kancane ukuthi izibani ze-LED azisizanga nje kuphela ukonga amandla kodwa futhi zinikeza imiphumela engcono yokukhanyisa, zaba yintandokazi entsha embonini yokukhanyisa.
Ukuthuthukiswa okuphumelelayo kobuchwepheshe be-LED akushintshi nje kuphela isimo samanje semboni yokukhanyisa kodwa futhi kulethe ithemba elisha namathuba kubantu. Namuhla, izibani ze-LED zisetshenziswa kabanzi emikhakheni ehlukahlukene, zisinikeza izixazululo zokukhanyisa ezisebenzisa amandla amaningi, ezinobungani nemvelo, nezisebenza kahle. Uhlobo lokushintshashintsha lwalobu buchwepheshe luzoqhubeka nokuhola imboni yokukhanyisa phambili, lusilethele ikusasa eliqhakazile.
Njengoba isisho sithi, "Ukukhanya koguquko kukhanyisa ikusasa." Uguquko lobuchwepheshe be-LED seluqalile kakade, futhi sibheke phambili ekusiletheleni ikusasa eliqhakazile.
