Kungani i-LED ibhekwa njengokukhanya kobuchwepheshe bokonga amandla?

Ngokuhamba kwesikhathi, abantu baqala ukuthuthukisa ukuqonda okujulile kwemfucuza yamandla ehambisana nezibani zendabuko ze-incandescent. Naphezu kokuphumelela kwawo okuphawulekayo ekunikezeni ukukhanya, izibani ze-incandescent zinenkinga yokuguqula ingxenye enkulu yamandla ibe ukushisa kunokukhanya, okubangele ukusebenza kahle kwamandla ngokuqhathaniswa.

Ngalesi sikhathi esibalulekile, umsunguli ogama lakhe lingu-Edison waqhubekela phambili ephishekela ukonga amandla kanye nomoya wokusungula, waqala umsebenzi wokuthuthukisa ukukhanya kukagesi. Ngemva kokuhlola okuningi, ekugcineni wasungula uhlobo olusha lwesibani sikagesi - isibani se-incandescent. Lokhu okusunguliwe kuthuthukise kakhulu ukusebenza kahle kwezibani, nokho kuhlulekile ukubhekana nendaba eyisisekelo yokumosheka kwamandla.

Nokho, ngesikhathi abantu besabhekene nale nkinga, kwavela ubuchwepheshe be-LED (Light Emitting Diode). Izibani ze-LED zisebenzisa izinto zokwakha ze-semiconductor ukuze zikhiphe ukukhanya, kunokuba zishise imicu yensimbi ukuze zikhiqize ukukhanya, ngaleyo ndlela ziguqule imboni yokukhanyisa. Izibani ze-LED azigcini nje ngokunikeza ukusebenza kahle kwamandla okuphezulu, cishe wonke amandla aguqulwa abe ukukhanya kunokushisa, kodwa futhi aziqhayisa ukuphila okude nokuphuma kokukhanya okucacile, okuba isithandwa esisha semboni yokukhanyisa.

Ngokukhula okuqhubekayo nokuthandwa kobuchwepheshe be-LED, izibani ze-LED zaqala ukusetshenziswa kakhulu emikhakheni ehlukahlukene. Kusukela ekukhanyisweni kwendlu kuya ekukhanyisweni kwezentengiselwano, kusukela ezibani zezimoto kuya kuzikrini zethelevishini, ubuchwepheshe be-LED bulethe uguquko embonini yokukhanyisa. Abantu baqaphela kancane kancane ukuthi izibani ze-LED azisizanga nje kuphela ukulondoloza amandla kodwa futhi zanikeza imiphumela engcono yokukhanyisa, zaba intandokazi entsha yemboni yokukhanyisa.

Ukuthuthukiswa kwentuthuko yobuchwepheshe be-LED akugcinanga ngokushintsha isimo samanje semboni yezibani kodwa kuphinde kwaletha ithemba namathuba amasha kubantu. Namuhla, izibani ze-LED zisetshenziswa kabanzi emikhakheni ehlukahlukene, zisinikeza izixazululo zokukhanyisa ezonga kakhulu, ezihambisana nemvelo, nezisebenza kahle. Isimo soguquko salobu buchwepheshe sizoqhubeka nokuholela phambili imboni yokukhanyisa, ilethe ikusasa eliqhakazile.

Njengoba isisho sithi, "Ukukhanya kwenguquko kukhanyisa ikusasa." Inguquko yobuchwepheshe be-LED isivele iqalile, futhi sibheke ngabomvu ukuthi isilethele ikusasa eliqhakazile.
