Cishe wonke amafoni amakhamera namuhla angasetshenziswa njengamakhamera edijithali.Impela, abasebenzisi bafuna ukuthatha izithombe zekhwalithi ephezulu ngisho nasezimeni zokukhanya okuphansi.Ngakho-ke, ifoni yekhamera idinga ukwengeza umthombo wokukhanya wokukhanyisa futhi ayisheshi ikhiphe ibhethri yefoni.Qala ukuvela.Ama-LED amhlophe asetshenziswa kakhulu njengokukhanya kwekhamera kumafoni ekhamera.Manje sekunokukhanya kwekhamera yedijithali okubili ongakhetha kukho: amashubhu e-xenon flash nama-LED amhlophe.I-Xenon flash isetshenziswa kakhulu kumakhamera wefilimu kanye namakhamera edijithali azimele ngenxa yokukhanya kwayo okuphezulu nokukhanya okumhlophe.Amafoni amaningi amakhamera akhethe ukukhanya kwe-LED okumhlophe.

1. Isivinini se-strobe se-LED siyashesha kunanoma yimuphi umthombo wokukhanya

I-LED iyidivayisi eshayelwa manje, futhi ukukhanya kwayo kunqunywa ukudluliswa kwamanje okuya phambili.Ijubane le-strobe le-LED liyashesha kunanoma yimuphi omunye umthombo wokukhanya, okuhlanganisa isibani se-xenon, esinesikhathi esifushane kakhulu sokuphakama, esisuka ku-10ns kuya ku-100ns.Izinga lokukhanyisa lama-LED amhlophe manje seliqhathaniswa nelamalambu apholile amhlophe e-fluorescent, futhi inkomba yokusebenza kombala isondele ku-85.

2. I-flash ye-LED inokusetshenziswa kwamandla okuphansi

Uma kuqhathaniswa namalambu e-xenon flash, amalambu e-LED asebenzisa amandla aphansi.Kuzinhlelo zokusebenza ze-flashlight, i-pulse current enomjikelezo omncane womsebenzi ingasetshenziswa ukushayela i-LED.Lokhu kuvumela okukhiphayo kwamanje kanye nokukhanya okukhiqizwa amandla amanje ukuthi kwenyuke kakhulu ngesikhathi sokushaya kwangempela, kuyilapho kugcina izinga lamanje elimaphakathi kanye nokusetshenziswa kwamandla kwe-LED ngaphakathi kwesilinganiso sayo esiphephile.

3. Isekethe yedrayivu ye-LED ithatha isikhala esincane futhi ukuphazamiseka kukagesi (EMI) kuncane

4. I-flash ye-LED ingasetshenziswa njengomthombo wokukhanya oqhubekayo

Ngenxa yezici zezibani ze-LED, ingasetshenziselwa izinhlelo zokusebenza zezithombe zefoni ephathekayo kanye nemisebenzi yethoshi.
