Ama-LED anamandla amakhulu njengemithombo yokukhanyisa asevele akhona yonke indawo, kodwa kungakanani okwaziyo ngama-LED, futhi okulandelayo kuzokuthatha ukuthi ufunde ulwazi oluthile mayelana nama-LED.
Izici zokukhipha ukukhanya kwama-LED
Ngokuthuthuka okusheshayo kobuchwepheshe be-LED, izinkomba zokusebenza zithuthuke kakhulu.Ikakhulukazi, ukusebenza kwama-LED amhlophe anamandla amakhulu, okuyizibani eziyinhloko zokukhanyisa kwesizukulwane sesine, kuye kwathuthukiswa kakhulu.Ngokwezidingo ezihlukene zokusetshenziswa, amandla ephakethe elilodwa ahlukaniswa: kusuka ku-1 ~ 10W kuya kumakhulu ama-watts, amakhulu ama-watts;Kusukela ezicini zokukhanya kokukhanya okukhipha ukukhanya kwelensi yephakeji ye-LED, eziyinhloko yilezi: Uhlobo lwe-Lambertian, uhlobo lokukhanya okusemaceleni, uhlobo lwephiko lelulwane, uhlobo lokugxilisa ingqondo (ukungqubuzana) nezinye izinhlobo, futhi ijika lesici lokukhipha liboniswa esithombeni.
Njengamanje, i-LED emhlophe yohlobo lwamandla iyathuthuka ibheke kumandla aphezulu we-chip eyodwa, kodwa ngenxa yezingqinamba zebhodlela lokukhipha ukushisa kwe-chip, ukuchithwa kokushisa kwe-single chip ultra-large power LED kusetshenziswa ukuhlanganisa inhlanganisela ye-multi-chip. Kunzima uma kuqhathaniswa, futhi ukusebenza kahle kokukhanya kuphansi uma kuqhathaniswa.Ekuklanyweni kwezibani zasemgwaqweni ze-LED ezinamandla amakhulu, ukukhethwa kwama-LED anamandla amakhulu kudinga ukucabangela izindaba eziningi ezifana nezici zokupakisha eziyinhloko, ukusebenza kahle okukhanyayo, izidingo zenqubo yokufaka, okwesibili kanye idizayini yokusabalalisa ukukhanya okuphakeme, indawo yokusebenzisa, izimo zokulahla ukushisa, nezici zokukhiphayo zesilawuli sedrayivu.Ngakho-ke, kuhlanganiswe nezici ezingenhla, kanye nezicelo ezingokoqobo, umkhuba ojwayelekile wokukhetha i-LED ezibanini zasemgwaqweni yilokhu: amandla e-LED eyodwa acishe abe yi-watt engu-1 ukuya kuma-watts amaningana, ukunikezwa kombala okuhle, izinga lokushisa lombala elingaguquki, ukukhanya okusebenzayo okungu-90. ~100 lm/W imikhiqizo yekhwalithi ephezulu iyinketho engcono kakhulu yokuklama.Ngamandla esibani somgwaqo, amandla okukhanya okuphelele adingekayo atholakala ngokuxuba ama-array amaningi;Ngokuqondene nezici zokukhishwa kokukhanya, uhlobo lwe-Lambertian, uhlobo lwe-batwing kanye nohlobo lwe-condenser lusetshenziswa kakhulu, kodwa ngokuvamile alukwazi ukusetshenziswa ngokuqondile ezibanini zasemgwaqweni, kufanele lube ngomklamo wokusabalalisa ukukhanya futhi ukuze kuhlangatshezwane nezidingo zokukhanyisa komgwaqo zezici zokuphuma kokukhanya.
