Ukukhanyisa kwe-LED sekuphenduke imboni ekhuthazwa ngamandla e-China ngenxa yezinzuzo zayo zokuvikela imvelo nokongiwa kwamandla. Inqubomgomo yokuvimbela ama-incandescent bulbs isetshenziswe ngokuhambisana nemithethonqubo efanele, okuholele ekutheni ama-giants embonini yokukhanyisa yendabuko ancintisane embonini ye-LED. Namuhla, imakethe ithuthuka ngokushesha. Ngakho-ke, siyini isimo sokuthuthukiswa kwemikhiqizo ye-LED emhlabeni?

Ngokusho kokuhlaziywa kwedatha, ukusetshenziswa kukagesi okukhanyisa umhlaba wonke kubala i-20% yengqikithi yokusetshenziswa kukagesi yonyaka, lapho kufika ku-90% iguqulwa ibe ukusetshenziswa kwamandla okushisa, okungagcini nje ngokuntula izinzuzo zezomnotho. Ngokombono wokongiwa kwamandla kanye nokuvikelwa kwemvelo, ukukhanyisa kwe-LED akungabazeki ukuthi kube ubuchwepheshe obubhekwa kakhulu kanye nemboni. Khonamanjalo, ohulumeni emhlabeni wonke bamatasa bakha imithetho yezemvelo ukuze bavimbele ukusetshenziswa kwezibani ze-incandescent. Iziqhwaga ezikhanyisayo zendabuko zethula imithombo emisha yokukhanya kwe-LED, zisheshisa ukwakheka kwamamodeli ebhizinisi amasha. Ikhuthazwa izintshisekelo ezimbili zemakethe nemithethonqubo, i-LED ithuthuka ngokushesha emhlabeni jikelele.

Izinzuzo ze-LED ziningi, nokusebenza kahle kokukhanya okuphezulu nokuphila isikhathi eside. Ukusebenza kwayo okukhanyayo kungafinyelela izikhathi ezingu-2,5 kunamalambu e-fluorescent kanye nezikhathi ezingu-13 kunamalambu e-incandescent. Ukusebenza kahle okukhanyayo kwezibani ze-incandescent kuphansi kakhulu, kuphela u-5% wamandla kagesi aguqulwa abe amandla okukhanya, futhi u-95% wamandla kagesi aguqulwa abe amandla okushisa. Amalambu e-Fluorescent angcono uma kuqhathaniswa namalambu e-incandescent, njengoba eguqula u-20% kuya ku-25% wamandla kagesi abe amandla okukhanya, kodwa futhi amoshe u-75% kuya ku-80% wamandla kagesi. Ngakho ngokombono wokonga kwamandla, yomibili le mithombo yokukhanya isiphelelwe yisikhathi kakhulu.

Izinzuzo ezikhiqizwa ukukhanya kwe-LED nazo azibaleki. Kubikwa ukuthi i-Australia yaba yizwe lokuqala emhlabeni ukwethula imithethonqubo evimbela ukusetshenziswa kwezibani ze-incandescent ngo-2007, futhi i-European Union iphinde yaphasisa imithetho yokukhishwa kwama-incandescent bulb ngo-March 2009. Ngakho-ke, izinkampani ezimbili ezinkulu ezikhanyisa izibani zendabuko, i-Osram. kanye ne-Philips, baye basheshisa ukwakheka kwabo emkhakheni wokukhanyisa kwe-LED eminyakeni yamuva. Ukungena kwabo kukhuthaze ukuthuthuka okusheshayo kwemakethe yezibani ze-LED futhi kuphinde kwasheshisa ijubane lokuthuthuka kobuchwepheshe be-LED emhlabeni jikelele.

Nakuba imboni ye-LED ithuthuka kahle emkhakheni wokukhanyisa, umcimbi we-homogenization uya ngokuya ubonakala, futhi akunakwenzeka ukwakha imiklamo ehlukahlukene emisha. Ngokufeza lokhu kuphela lapho singama siqine embonini ye-LED.
