Pafupifupi mafoni onse amakamera masiku ano atha kugwiritsidwa ntchito ngati makamera a digito.Inde, ogwiritsa ntchito amafuna kujambula zithunzi zapamwamba ngakhale mumdima wochepa.Chifukwa chake, foni ya kamera imayenera kuwonjezera gwero lounikira ndipo simakhetsa batire la foni mwachangu.Yambani kuwonekera.Ma LED oyera amagwiritsidwa ntchito kwambiri ngati kuwala kwa kamera m'mafoni a kamera.Tsopano pali zowunikira ziwiri zamakamera a digito oti musankhe: machubu a xenon flash ndi ma LED a kuwala koyera.Kung'anima kwa Xenon kumagwiritsidwa ntchito kwambiri m'makamera amafilimu ndi makamera odziyimira pawokha a digito chifukwa chowala kwambiri komanso kuwala koyera.Mafoni ambiri a kamera asankha kuyatsa koyera kwa LED.

1. Kuthamanga kwa strobe kwa LED ndikothamanga kuposa gwero lililonse la kuwala

LED ndi chipangizo choyendetsedwa pakali pano, ndipo kuwala kwake kumatsimikiziridwa ndi kutsogolo komwe kukupita.Kuthamanga kwa strobe kwa LED ndikothamanga kuposa kuwala kwina kulikonse, kuphatikiza nyali ya xenon, yomwe imakhala ndi nthawi yayitali kwambiri, kuyambira 10ns mpaka 100ns.Kuunikira kwa ma LED oyera tsopano akufanana ndi nyali zoyera zoyera za fulorosenti, ndipo mtundu wa magwiridwe antchito uli pafupi ndi 85.

2. Kuwala kwa LED kumakhala ndi mphamvu zochepa

Poyerekeza ndi nyali za xenon, nyali za LED zimakhala ndi mphamvu zochepa.Muzowunikira tochi, ma pulse current okhala ndi kagawo kakang'ono kantchito angagwiritsidwe ntchito kuyendetsa ma LED.Izi zimathandiza kuti pakalipano komanso kuwala komwe kumachokera pakalipano kuchuluke kwambiri panthawi yothamanga kwenikweni, ndikusungabe mlingo wamakono ndi kugwiritsa ntchito mphamvu za LED mkati mwa chiwerengero chake chotetezeka.

3. Dongosolo loyendetsa galimoto la LED limakhala ndi malo ang'onoang'ono komanso kusokoneza kwa electromagnetic (EMI) ndi kochepa

4. Kuwala kwa LED kungagwiritsidwe ntchito ngati gwero la kuwala kosalekeza

Chifukwa cha mawonekedwe a magetsi a LED, amatha kugwiritsidwa ntchito pojambula zithunzi za foni yam'manja ndi ntchito za tochi.
