Ngenkqubela phambili kunye nophuhliso loluntu, imiba yamandla kunye nokusingqongileyo iye yanda ukuba yingqwalasela yehlabathi. Ukulondolozwa kwamandla kunye nokukhuselwa kwendalo kuye kwanda ukuba yeyona nto iqhuba inkqubela phambili yoluntu. Kubomi bemihla ngemihla yabantu, imfuno yamandla okukhanyisa ibalelwa kumlinganiselo omkhulu kakhulu wokusetyenziswa kwamandla apheleleyo, kodwa iindlela ezikhoyo zokukhanyisa zemveli zineziphene ezifana nokusetyenziswa kwamandla amakhulu, ubomi obufutshane benkonzo, ukusebenza kakuhle koguqulo oluphantsi kunye nongcoliseko lokusingqongileyo. ngokuhambelana nenjongo yokonga amandla kunye nokukhusela okusingqongileyo kuluntu lwanamhlanje, Ngoko ke, imowudi entsha yokukhanyisa ehlangabezana neemfuno zophuhliso loluntu iyadingeka ukuba ithathe indawo yokukhanya kwendabuko.

Ngemigudu eqhubekayo yabaphandi, imowudi yokukhanyisa eluhlaza kunye nobomi benkonzo obude, ukusebenza kakuhle kokuguqulwa kunye nongcoliseko oluphantsi lokusingqongileyo, oko kukuthi i-semiconductor white light emitting diode.WLED), sele ilungisiwe. Xa kuthelekiswa nemodi yokukhanyisa yendabuko, i-WLED inenzuzo yokusebenza okuphezulu, akukho ngcoliseko ye-mercury, ukukhutshwa kwekhabhoni ephantsi, ubomi benkonzo ende, umthamo omncinci kunye nokugcinwa kwamandla, Oku kwenza ukuba kusetyenziswe ngokubanzi ukuthutha, ukubonakalisa ukukhanya, izixhobo zonyango kunye neemveliso zombane.

Ngaxeshanye,I-LEDiye yamkelwa njengowona mthombo wokukhanya uxabisekileyo kule nkulungwane yama-21. Ngaphantsi kweemeko ezifanayo zokukhanyisa, ukusetyenziswa kwamandla e-WLED kulingana ne-50% yezibane ze-fluorescent kunye ne-20% yezibane ze-incandescent. Ngokwangoku, ukusetyenziswa kwamandla okukhanyisa ngokwesiqhelo kumalunga ne-13% yokusetyenziswa kwamandla ehlabathi. Ukuba i-WLED isetyenziselwa ukubuyisela umthombo wokukhanyisa wemveli wehlabathi, ukusetyenziswa kwamandla kuya kuncitshiswa malunga nesiqingatha, kunye nesiphumo esimangalisayo sokugcina amandla kunye neenzuzo zezoqoqosho ezinenjongo.

Okwangoku, i-white light emitting diode (i-WLED), eyaziwa ngokuba sisixhobo sokukhanyisa isizukulwana sesine, iye yatsala ingqalelo enkulu ngenxa yokusebenza kwayo kakuhle. Abantu baye bomeleza ngokuthe ngcembe uphando kwi-LED emhlophe, kwaye izixhobo zayo zisetyenziswa ngokubanzi kwiinkalo ezininzi ezifana nokubonisa kunye nokukhanyisa.

Ngo-1993, itekhnoloji ye-Gan blue light emitting diode (LED) yenza impumelelo okokuqala, ekhuthaza uphuhliso lwe-LED. Ekuqaleni, abaphandi basebenzise i-Gan njengomthombo wokukhanya okuluhlaza okwesibhakabhaka kwaye baqaphela ukukhanya okumhlophe okuphumayo kweyodwa ekhokelwa ngokusebenzisa indlela yokuguqula i-phosphor, eyakhawuleza isantya se-LED engena kwindawo yokukhanyisa.

Esona sicelo sikhulu se-WLED sikwintsimi yokukhanya kwendlu, kodwa ngokwemeko yophando lwangoku, i-WLED iseneengxaki ezinkulu. Ukuze senze i-WLED ingene ebomini bethu ngokukhawuleza, kufuneka siphucule rhoqo kwaye siphucule ukusebenza kwayo okukhanyayo, ukunikezelwa kombala kunye nobomi benkonzo. Nangona umthombo wokukhanya we-LED wangoku awukwazi ukubuyisela ngokupheleleyo umthombo wokukhanya wendabuko osetyenziswa ngabantu, kunye nophuhliso lwesayensi kunye nobuchwepheshe, izibane ze-LED ziya kuba zithandwa kakhulu.
