Amandla e-IR aphezulu.
Sibonelela ngombane ophakamileyo ngeemveliso zamandla ombane, ezinje nge: 0.5W 940nm Amandla aphezulu e-IR LED, 1w 940nm Amandla aphezulu e-IR, 2W 940nm amandla aphezulu e-IR, 2w 940nm amandla aphezulu e-IR, 3W 940nm Amandla aphezulu e-IR, 0.5W 850nm Amandla aphezulu e-IR LED, 1w 850nm Amandla aphezulu e-IR LED, 2W 850nm amandla aphezulu e-IR LED, 3W 850nm amandla aphezulu e-IR LED njalo njalo.
Ke yintoni umahluko phakathi kwe-940nm kunye ne-850nm?
Ii-infrared ze-940nm ze-infrared azibonakali ngamehlo, oko kuthetha ukuba awukwazi ukubona ukuba i-940nm iyasebenza okanye ayisebenzi. Ngaphandle kokuba uyibukele ngesixhobo esithile (njengekhamera yefowuni), eya kubonisa umbala omfusa okanye omhlophe.
Ii-infrared ze-850nm ze-LED zinombala obomvu kancinci xa usebenza, oko kuthetha ukuba unokubona ukuba ngaba i-850nm LED iyasebenza.
Ngaphantsi kwamandla afanayo, amandla emitha ye-850nm aya kuba phezulu kune-940nm. Ewe i-940nm ikwanazo neenzuzo zayo ezizodwa. Iliso lenyama elingabonakaliyo emsebenzini okanye emsebenzini, ke, isicelo salo sisetyenziswe ngokubanzi kwiimarike ezininzi ezikhethekileyo kweli xesha langoku.

Ukongeza, songeza iilensi ngaphezulu kwe-LED ye-SMD, enokwenza ukuba i-SMD ye-LED ibe ne-engile efana nezo zinemingxunya ye-LED, esiyibize ngokuba zii-'D Domed LEDs '.
Umzekelo: I-850nm yamandla aphakamileyo i-IR ye-IR eneedigri ezingama-30, 850nm amandla aphezulu e-IR LED eneedigri ezingama-60, i-850nm yamandla aphezulu e-IR nge-90 degrees, i-940nm yamandla aphezulu e-IR nge-30 degrees, i-940nm yamandla aphezulu e-IR nge-60 degrees, 940nm High I-IR ye-IR yamandla ineedigri ezingama-90, njl.Sinokwenza ngokusesikweni ukungunda kweedns njengoko ufuna i-engile.
Sivelisa kwaye sithengise amandla aphezulu e-IR ye-IR, ekwi-wavelength ukusuka kwi-680nm-1550nm.
Kolu luhlu, ikakhulu sizisa ezi ndidi zimbini ze-wavelengths: 940nm IR LED kunye ne-850nm IR LED. Ezi zimbini zeevelengths zezona ziqhelekileyo ezisetyenziswayo kwi-infrared esweni. Zonke zinokusetyenziselwa ukubeka esweni iimveliso.
