Kuyini ukuncishiswa kokukhanya kwe-LED?
Ukunciphisa ukukhanya kwe-LED kubhekisela ekukhanyeni kokukhanya kwe-LED kuzoba ngaphansi kokuqina kokukhanya kwasekuqaleni ngemva kokukhanyisa, futhi ingxenye engezansi ukuncishiswa kokukhanya kwe-LED. Ngokuvamile, abakhiqizi bephakeji le-LED benza isivivinyo ngaphansi kwezimo zaselabhorethri (emazingeni okushisa ajwayelekile angama-25 ° C), futhi ngokuqhubekayo bakhanyise i-LED ngamandla eDC angama-20MA amahora ayi-1000 ukuze baqhathanise amandla okukhanya ngaphambi nangemva kokukhanyisa ukukhanya. .
Indlela yokubala yokunciphisa ukukhanya
Ukunciphisa ukukhanya kwehora elingu-N = 1- (i-N-hour light flux / 0-hour light flux)
Ukunciphisa ukukhanya kwama-LED akhiqizwa izinkampani ezihlukahlukene kuhlukile, futhi ama-LED anamandla aphezulu azophinde abe nokunciphisa ukukhanya, futhi anobudlelwane obuqondile nokushisa, okuncike kakhulu ku-chip, i-phosphor kanye nobuchwepheshe bokupakisha. Ukuncishiswa okukhanyayo kwama-LED (okuhlanganisa nokuncishiswa kwe-flux ekhanyayo, ukushintsha kombala, njll.) kuyisilinganiso sekhwalithi ye-LED, futhi kuyindaba ekhathaza kakhulu abakhiqizi abaningi be-LED nabasebenzisi be-LED.
Ngokwencazelo yempilo yemikhiqizo ye-LED embonini ye-LED, impilo ye-LED isikhathi sokusebenza esiqongelelayo ukusuka enanini lokuqala ukuya ekunyamalalelweni kokukhanya kuye ku-50% yenani lokuqala. Kusho ukuthi uma i-LED ifinyelela impilo yayo ewusizo, i-LED isazokhanya. Nokho, ngaphansi kokukhanyisa, uma ukukhanya kuncishiswa ngo-50%, akukho kukhanya okuvunyelwe. Ngokuvamile, ukuncishiswa kokukhanya kokukhanya kwangaphakathi akukwazi ukuba kukhulu kuno-20%, futhi ukuncishiswa kokukhanya kokukhanya kwangaphandle akukwazi ukuba kukhulu kuno-30%.
