Uyazazi izindinganiso ezine ezinkulu zobuchwepheshe zezibani ze-LED ezingaqhumi?
Isibani se-LED sokuvikela ukuqhuma singesinye sezibani ezivikela ukuqhuma.Isimiso saso siyefana naleso sesibani esingaqhumi.Umehluko wukuthi umthombo wokukhanya osetshenziswayo ungumthombo wokukhanya we-LED, okubhekiselwa kusibani esithatha izinyathelo ezithile eziqondile ukuvimbela ingxube eqhumayo ezungezile ukuthi ingashi.Ngakho-ke, kubaluleke kakhulu kithi ukuthi sithenge izibani ze-LED ezingaqhumisi.Lapho uthenga, sidinga ukuqonda amazinga amane amakhulu obuchwepheshe amalambu angaqhumi e-LED.
1. Umthombo wokukhanya we-LED
Kusetshenziswa ukukhanya okuphezulu kwamanye amazwe, ukusebenza kahle okuphezulu kanye nokubola kancane ukukhanya kwe-LED chips, futhi izinto ezihlangabezana nezidingo ziyasetshenziswa, njengezibani ze-phosphor zegolide ezipakishwe.Lapho uthenga, sicela ukhethe izibani zezimboni ezisetshenziselwa ukukhiqiza.
2. Amandla okushayela
I-LED iyingxenye ye-semiconductor eguqula ama-electron e-DC abe amandla okukhanya, ngakho ukushayela okuzinzile kudinga ama-chips okushayela amandla asebenza kahle kakhulu, kanye nemisebenzi yesinxephezelo yesici samandla se-PU iyadingeka ukuze kuqinisekiswe ukusebenza kahle kwamandla.Amandla ayisici esiyinhloko saso sonke isibani.Njengamanje, ikhwalithi yamandla kagesi we-LED emakethe ayilingani futhi ixubile.Ukunikezwa kwamandla okushayela okuhle akuqinisekisi kuphela ukuphuma kwe-DC okuzinzile, kodwa futhi kuqinisekisa ngokugcwele ukuthuthukiswa kokusebenza kahle kokuguqulwa.Le parameter ibonisa uhlobo lwelambu langempela lokonga amandla futhi ngeke libangele udoti kugridi yamandla.
3. Ukubukeka nokwakheka kwesibani se-LED esingaqhumisi kanye nesistimu yokukhipha ukushisa eqinile
Ngaphandle kokubukeka okuphezulu, umthombo wokukhanya wekhwalithi ephezulu kanye nokunikezwa kwamandla, isibani esihle sibaluleke kakhulu ukuhlakanipha kwesakhiwo segobolondo.Kubandakanya inkinga yokushisa kwesibani se-LED.Njengoba i-LED iguqula amandla esibani, ingxenye yamandla kagesi nayo iguqulwa ibe amandla okushisa.Umthofu oshisayo ukhishelwa emoyeni ukuze kuqinisekiswe ukuzinza kwesibani se-LED.Ukushisa okuphezulu kwesibani se-LED kuzosheshisa ukubola kokukhanya futhi kuthinte impilo yesibani se-LED.Kuhle ukusho ukuthi ubuchwepheshe be-chip ye-LED buhlala buthuthuka, futhi ukusebenza kahle kokuguqulwa nakho kuyathuthuka.Ukushisa okusetshenziswe ekuguqulweni kwamandla kagesi kuzoba kuncane, futhi idivayisi yokukhipha ukushisa izoba mncane.Futhi ngoba ezinye zezindleko eziphansi zinenzuzo ku-LED, kodwa lokhu Ingabe nje isiqondiso sokuthuthukiswa kwezobuchwepheshe, imingcele yamanje yokushisa ukushisa kwezindlu kufanele inakwe.
Okwesine, ilensi yesibani se-LED esingaqhumi
Ivamise ukunganakwa ngabanye abaklami.Eqinisweni, ukulahlekelwa ukukhanya kuzokwenzeka.Inkomba ye-refractive yelensi ekukhanyeni nayo ithinta ngokujulile ukuphuma kokukhanya okukhanyayo.I-lens transmittance engcono ingafinyelela ngaphezu kwama-93. Ngenxa yezindleko, ikhwalithi yelensi nayo ibaluleke kakhulu.Ngakho-ke, ukuze kongiwe izindleko, abanye abakhiqizi basebenzisa izinto ezishibhile zamalensi okufanele zibe izinto zesibili futhi zibe nokudlulisa ukukhanya okungaba ngamaRandi angu-70, okungabonakali ngeso lenyama futhi kukhohlise abathengi.Nokho, imiphumela yokuhlolwa kwezinsimbi zabo ezingokoqobo ilula kakhulu.Impahla impofu kakhulu, futhi izophenduka ibe phuzi ngemva kwesikhathi eside.
