Njengamanje, izinga lekhwalithi yezibani ze-LED zomgwaqo emakethe alilingani.Ezindaweni eziningi, izibani zasemgwaqweni ze-LED ngeke zibonakale zikhanya maduzane.Ngemuva kocwaningo lwe-Led street lights Manufacturers, imbangela eyinhloko yalesi simo ukuthi ukukhanya komgwaqo we-LED kunomsebenzi omubi wokushisa ukushisa.Uma ukusebenza kokukhishwa kokushisa kungalungile, izinga lokushisa langaphakathi lokukhanya kwe-LED lizoba phezulu kakhulu.Lapho izinga lokushisa le-LED likhuphuka, ukumelana kwayo kwe-junction kuncipha, okuholela ekunciphiseni kwe-voltage yokuvula.
Ngaphansi kwezimo ezifanayo ze-voltage, ukunyuka kwezinga lokushisa kwangaphakathi kwesibani se-LED kuzokhuphula i-LED yamanje.Ukwanda kwamanje kubangela ukuthi izinga lokushisa likhuphuke ngokuqhubekayo, okubangela ukuthi umjikelezo omubi ushise i-chip ye-LED.Ngaphezu kwalokho, izinga lokushisa langaphakathi lokukhanya komgwaqo we-LED liphezulu kakhulu, okwenza futhi ukubola kokukhanya kwe-chip ye-LED kuqiniswe, ukuze kuholele entweni ekhanyayo futhi engakhanyi esikhathini esizayo esiseduze.Ngakho-ke siyini isizathu sokusebenza kabi kokushisa kokushisa kokukhanya komgwaqo we-LED?
Okokuqala, ikhwalithi ye-LED street lights ngokwayo.
I-chip ye-LED esetshenzisiwe ine-conductivity ephansi ye-thermal, futhi izinga lokushisa le-LED die alidluliswanga phezulu (ukushisa kwangaphakathi nokubanda).Ngisho noma i-sink yokushisa ingeziwe, ukushisa kwangaphakathi akukwazi ukuchithwa ngokuphelele, bese ukukhanya komgwaqo we-LED akushisi ngaphakathi.
Okwesibili, ukunyuka kwezinga lokushisa okubangelwa ukukhanya kokukhanya komgwaqo we-LED.
Ikhwalithi yamandla okukhanya komgwaqo we-LED ayilungile.Uma i-LED ivuliwe, ukungewona umugqa wokunikezwa kwamandla kanye nokushintsha okubuthakathaka kwamandla kuzobangela ukuthi i-current nge-chip ye-LED ikhule, okuzokwenza ukuthi izinga lokushisa langaphakathi libe phezulu kakhulu, okuzothinta ukushisa. ukusebenza kokukhanya kwesibani somgwaqo we-LED.
Wonke umuntu udinga ukunaka impilo ende yezibani zomgwaqo ze-LED.Lapho uthenga, zama ukukhetha abakhiqizi bezibani zomgwaqo ezithembekile ze-LED, futhi futhi unake ukugcinwa okuvamile, ukuze uqinisekise ukuzinza kwezibani zomgwaqo ze-LED.
