Nazi iingenelo zobuchwepheshe bokukhanyisa i-diode yokukhanya. Ndiyathemba ukuba oku kunokukunceda wazi ngakumbi malunga nezibane ze-LED.

1. Ubomi bokukhanya kwe-LED:

Ngokulula olona ncedo lubalulekileyo lwee-LEDs xa kuthelekiswa nezisombululo zokukhanya zesiNtu bubomi obude. Umyinge we-LED uhlala iiyure zokusebenza ezingama-50,000 ukuya kwiiyure zokusebenza ezingama-100,000 okanye ngaphezulu. Oko kumaxesha angama-2-4 ubude njengobuninzi be-fluorescent, i-metal halide, kunye nezibane zomphunga zesodium. Ingaphezulu kwamaxesha angama-40 ubude njengebhalbhu ye-incandescent ephakathi.

2. Ukuphumelela koMbane we-LED:

Ii-LEDs ngokubanzi zisebenzisa amandla aphantsi kakhulu. Amanani okukhangela xa kuthelekiswa amandla ombane wezisombululo ezahlukeneyo zokukhanyisa zibizwa ngelinye lamagama amabini: ukusebenza okukhanyayo okanye i-lumens eluncedo. Ezi zinto zimbini zichaza ubukhulu bokukhanya okukhutshiweyo ngeyunithi yombane (watts) esetyenziswe yibhalbhu. Ngokophando, uninzi lweeprojekthi zokulungisa izibane ze-LED zikhokelela kuphuculo lwe-60-75% kumandla ombane apheleleyo kwizibane zezibane. Ngokuxhomekeke kwizibane ezikhoyo kunye nee-LED ezithile ezifakelweyo, ugcino lunokuba ngaphezulu kwe-90%.

3. Ukhuseleko oluphuculweyo ngee-LEDs:

Ukhuseleko mhlawumbi lolona ncedo luhlala lungahoywa xa kufikwa kwizibane ze-LED. Ingozi enye xa kufikwa ekukhanyeni kukukhutshwa kobushushu. Ii-LED zikhupha phantse akukho bushushu bangaphambili ngelixa iibhalbhu zemveli ezifana ne-incandescents ziguqula ngaphezu kwe-90% yamandla ewonke asetyenziselwa ukuwenza ngokuthe ngqo kubushushu. Oko kuthetha ukuba kuphela i-10% yamandla ombane we-incandescent izibane ezisetyenziselwa ukukhanya.

Ukongezelela, ngenxa yokuba ii-LED zisebenzisa amandla amancinci zinokusebenza ngokufanelekileyo kwiinkqubo zombane eziphantsi. Ezi ngokuqhelekileyo zikhuseleke ngakumbi xa kukho into engahambi kakuhle.

4. Izibane ze-LED ziNcinane ngokwaseMzimbeni:

Isixhobo sokwenyani se-LED sincinci kakhulu. Izixhobo ezincinci zamandla zinokuba ngaphantsi kweshumi le-mm enye²ngelixa izixhobo ezinkulu zamandla zisengabancinci njenge mm². Ubungakanani babo obuncinci benza ii-LED zilungelelanise ngokumangalisayo kwinani elingenasiphelo lezicelo zokukhanyisa. Ukusetyenziswa okuhlukeneyo kwee-LED kubandakanya i-spectrum ebanzi ukusuka kwiingcambu zabo ekukhanyeni kwebhodi yesekethe kunye neempawu zendlela yokukhanya kwemizwelo yanamhlanje, indawo yokuhlala, izicelo zepropati zorhwebo, njalo njalo.

5. Ii-LED zinoMbala oMkhulu wokuBonelela iSalathiso (CRI):

I-CRI, umlinganiselo wokukwazi kokukhanya ukuveza owona mbala wezinto xa kuthelekiswa nomthombo wokukhanya ofanelekileyo (ukukhanya kwendalo). Ngokuqhelekileyo, i-CRI ephezulu luphawu olunqwenelekayo. Ii-LED zihlala zinemilinganiselo ephezulu kakhulu xa ifika kwi-CRI.

Mhlawumbi enye yeyona ndlela isebenzayo yokuxabisa i-CRI kukujonga uthelekiso oluthe ngqo phakathi kokukhanya kwe-LED kunye nesisombululo sokukhanyisa ngokwesiko njengezibane zomphunga wesodium. Jonga lo mfanekiso ulandelayo ukuthelekisa kunye nokuthelekisa le mizekelo mibini:

Uluhlu lwamaxabiso anokwenzeka kwizibane ezahlukeneyo ze-LED ngokuqhelekileyo phakathi kwe-65 kunye ne-95 ebonwa njengegqwesileyo.
