t ngoku, umgangatho womgangatho wezibane zesitalato ze-LED kwimarike awulingani.Kwiindawo ezininzi, izibane ze-LED zesitrato aziyi kubonakala ngokukhawuleza.Emva kophando lweIzibane zesitrato ezikhokelweyo Abavelisi, ingcambu yonobangela wale nto kukuba ukukhanya kwesitalato se-LED kunomsebenzi ombi wokutshatyalaliswa kobushushu.Xa ukusebenza kokutshatyalaliswa kobushushu kungalunganga, ukushisa kwangaphakathi kokukhanya kwe-LED kuya kuba phezulu kakhulu.Xa ukushisa kwe-LED kuphakama, ukuchasana kwayo kwe-junction kuyancipha, okubangelwa ukuhla kwe-voltage yokuvula.
Ngaphantsi kweemeko zombane ezifanayo, ukunyuka kweqondo lokushisa kwangaphakathi kokukhanya kwe-LED kuya kwandisa i-LED yangoku.Ukunyuka kwangoku kubangela ukuba ukushisa kunyuke ngakumbi, okubangela ukuba umjikelezo ombi utshise i-chip ye-LED.Ngaphezu koko, ukushisa kwangaphakathi kokukhanya kwesitalato se-LED kuphezulu kakhulu, okubangela ukuba ukubola kokukhanya kwe-chip ye-LED kuqiniswe, ukwenzela ukuba kuya kukhokelela kwinto eqaqambileyo kwaye ingabi yinto eqaqambileyo kwixesha elizayo.Ke yintoni isizathu sokungasebenzi kakuhle kobushushu bokukhanya kwesitrato se-LED?
Okokuqala, umgangatho wezibane ze-LED zizibane ngokwazo.
I-chip ye-LED esetyenzisiweyo ine-conductivity ephantsi ye-thermal, kwaye ukushisa kwe-LED die ayidluliswanga phezulu (ubushushu bangaphakathi kunye nokubanda).Nangona i-heat sink yongezwa, ukushisa kwangaphakathi akukwazi ukuchithwa ngokupheleleyo, kwaye ke ukukhanya kwesitalato se-LED akushushu ngaphakathi.
Okwesibini, ukunyuka kweqondo lokushisa okubangelwa umbane wokukhanya kwesitrato se-LED.
Umgangatho wamandla okukhanya kwesitrato se-LED awulungile.Xa i-LED ivuliwe, ukungahambelani kombane kunye nokutshintsha okubuthathaka kombane kuya kubangela ukuba i-current ngokusebenzisa i-chip ye-LED inyuke, okuya kubangela ukuba ukushisa kwangaphakathi kube phezulu kakhulu, okuya kuchaphazela ubushushu. ukusebenza kokutshatyalaliswa kwesibane sesitrato se-LED.
Wonke umntu kufuneka anikele ingqalelo kwixesha elide lezibane zesitalato ze-LED.Xa kuthengwa, zama ukukhetha abavelisi bezibane ze-LED ezithembekileyo, kwaye ubeke ingqalelo ekugcinweni rhoqo, ukwenzela ukuba uqinisekise ukuzinza kwezibane zesitrato ze-LED.
