Nazi iingenelo zobuchwepheshe bokukhanyisa i-diode ekhupha ukukhanya. Ndiyathemba ukuba oku kunokukunceda wazi ngakumbi ngezibane ze-LED.

1. Ixesha loBomi boLwandiso lwe-LED:

Eyona nzuzo ibalulekileyo yee-LED xa ithelekiswa nezisombululo zokukhanyisa zemveli kukuphila ixesha elide. I-LED eqhelekileyo ihlala iiyure zokusebenza ezingama-50,000 ukuya kwiiyure zokusebenza ezili-100,000 nangaphezulu. Oko kuthetha ukuba ubude obuphindwe ka-2-4 kunobuninzi bezibane ze-fluorescent, metal halide, kunye ne-sodium vapor. Ingaphezulu ngokuphindwe ka-40 kunobungakanani bebhalbhu ye-incandescent.

2. Ukusebenza kakuhle kwamandla e-LED:

Ii-LED ngokubanzi zisebenzisa amandla aphantsi kakhulu. Izibalo ekufuneka zijongwe xa kuthelekiswa ukusebenza kakuhle kwamandla kwezisombululo ezahlukeneyo zokukhanyisa zibizwa ngelinye lamagama amabini: ukusebenza kakuhle kokukhanya okanye ii-lumens eziluncedo. Ezi zinto zimbini zichaza ngokusisiseko ubungakanani bokukhanya okukhutshwa ngeyunithi yamandla (ii-watts) ezisetyenziswa yibhalbhu. Ngokophando, uninzi lweeprojekthi zokulungisa ukukhanya kwe-LED ziphumela ekuphucukeni kwama-60-75% ekusebenzeni kakuhle kwamandla okukhanya kwesakhiwo. Ngokuxhomekeke kwizibane ezikhoyo kunye nee-LED ezithile ezifakiweyo, ukonga kungaba ngaphezulu kwama-90%.

3. Ukhuseleko oluphuculweyo ngee-LED:

Ukhuseleko mhlawumbi yeyona nzuzo ixhaphakileyo xa kufikwa ekukhanyeni kwe-LED. Ingozi yokuqala xa kufikwa ekukhanyeni kukukhupha ubushushu. Ii-LED azikhuphi bushushu obuphambili ngelixa iibhalbhu zemveli ezifana nee-incandescent ziguqula ngaphezulu kwe-90% yamandla apheleleyo asetyenziswayo ukuzinika amandla ngqo kubushushu. Oko kuthetha ukuba yi-10% kuphela yamandla asebenzisa izibane ze-incandescent asetyenziselwa ukukhanya.

Ukongeza, kuba ii-LED zisebenzisa amandla amancinci zinokusebenza ngokufanelekileyo kwiinkqubo zombane ezine-voltage ephantsi. Ezi zihlala zikhuselekile ngakumbi xa kukho into engahambi kakuhle.

4. Izibane ze-LED zincinci ngokwasemzimbeni:

Isixhobo se-LED sokwenyani sincinci kakhulu. Izixhobo zamandla ezincinci zinokuba ngaphantsi kwe-1/2 ye-mm enye.²ngelixa izixhobo zamandla ezinkulu zisenokuba zincinci njenge-mm². Ubungakanani bazo obuncinci benza ii-LED zikwazi ukuziqhelanisa nenani elingenamkhawulo lezicelo zokukhanyisa. Iindlela ezahlukeneyo zokusetyenziswa kwee-LED ziquka uluhlu olubanzi ukusuka kwiingcambu zazo kwizibane zesekethe kunye neempawu zendlela ukuya kwizibane zemood zanamhlanje, izicelo zokuhlala, zepropathi yorhwebo, njl.njl.

5. Ii-LED Zine-Great Color Rendering Index (CRI):

I-CRI, umlinganiselo wobuchule bokukhanya bokutyhila umbala wokwenyani wezinto xa kuthelekiswa nomthombo wokukhanya ofanelekileyo (ukukhanya kwendalo). Ngokubanzi, i-CRI ephezulu luphawu olufunekayo. Ii-LED zihlala zinezinga eliphezulu kakhulu xa kufikwa kwi-CRI.

Mhlawumbi enye yezona ndlela zisebenzayo zokuxabisa i-CRI kukujonga uthelekiso oluthe ngqo phakathi kokukhanya kwe-LED kunye nesisombululo sokukhanyisa sendabuko njengezibane zomphunga we-sodium. Jonga umfanekiso olandelayo ukuze uthelekise kwaye uthelekise ezi meko zimbini:

Uluhlu lwamaxabiso anokubakho kwizibane ze-LED ezahlukeneyo ngokubanzi luphakathi kwama-65 nama-95, nto leyo ethathwa njengelungileyo.
