Yintoni ukukhanya kwe-LED?
Ukunciphisa ukukhanya kwe-LED kubhekiselele kukukhanya kokukhanya kwe-LED kuya kuba ngaphantsi kokukhanya kokukhanya kokuqala emva kokukhanyisa, kwaye inxalenye engezantsi kukunciphisa ukukhanya kwe-LED. Ngokubanzi, abavelisi bephakeji ye-LED benza uvavanyo phantsi kweemeko zelabhoratri (kwiqondo lobushushu eliqhelekileyo lama-25 ° C), kwaye ngokuqhubekayo bakhanyisela i-LED ngamandla e-DC angama-20MA kwiiyure eziyi-1000 ukuthelekisa ukukhanya ngaphambi nasemva kokukhanyisa ukukhanya. .
Indlela yokubala yokunciphisa ukukhanya
Ukunciphisa ukukhanya kweyure ye-N = 1- (i-N-yure yokukhanya okuguquguqukayo / ukukhanya kweyure eyi-0)
Ukunciphisa ukukhanya kwee-LED eziveliswa ziinkampani ezahlukeneyo kwahlukile, kwaye ii-LED ezinamandla kakhulu ziya kuba nokunciphisa ukukhanya, kwaye inobudlelwane obuthe ngqo nobushushu, obuxhomekeke kakhulu kwi-chip, i-phosphor kunye neteknoloji yokupakisha. Ukutshatyalaliswa okukhanyayo kwee-LEDs (kubandakanywa nokutshatyalaliswa kwe-flux ekhanyayo, utshintsho lombala, njl.njl.) ngumlinganiselo womgangatho we-LED, kwaye yinto exhalabisa kakhulu kubakhiqizi abaninzi be-LED kunye nabasebenzisi be-LED.
Ngokwenkcazo yobomi beemveliso ze-LED kwishishini le-LED, ubomi be-LED lixesha lokusebenza elongezelelweyo ukusuka kwixabiso lokuqala ukuya ekunyamaleni kokukhanya ukuya kwi-50% yexabiso lokuqala. Kuthetha ukuba xa i-LED ifikelela kubomi bayo obuluncedo, i-LED iya kuhlala ivuliwe. Nangona kunjalo, phantsi kokukhanya, ukuba ukukhanya okukhanyayo kunqanyuliwe ngu-50%, akukho kukhanya kuvunyelwe. Ngokubanzi, ukuthotywa kokukhanya kwezibane zangaphakathi akunakuba ngaphezulu kwe-20%, kwaye ukukhanya kokukhanya kokukhanya kwangaphandle akunakuba ngaphezulu kwe-30%.
