- 940nm Ngakhale-Hole WOZIMBITSA -

Makona osiyana amapangitsa kuyatsa kosiyanasiyana, kutambalala kwachitsulo kocheperako, kutalika kwa radiation. Koma mtengo m'lifupi onse, zikuluzikulu kuyatsa padziko dera. Pali mitundu yowonera pamakina abwino kwambiri a LED omwe mungasankhe kuti muthe kusankha iliyonse mwazomwe mungagwiritse ntchito. Msika, anthu ambiri amagwiritsa ntchito 850nm LED kapena 940nm LED pakamera yamaso usiku. Ndiye mutha kudabwa, kodi 810nm LED silingagwire izi? Kudaliraku ndikuti , ma 810nm LED awa sangagwiritsidwe ntchito ngati chida chowonera usiku, komanso atha kugwira ntchito bwino kuposa 850nm LED. Zomwe zingalowe m'malo mwa 850nm LED ndikuwonjezera anthu kuzindikira nkhope. Mofanana ndi ma LED onse obowola, nyali za 810nm za infrared LED zilinso ndi mitundu yowonera omwe mwasankha: 5 degree 810nm LED, 20 degree 810nm LED, 30 degree 810nm LED, 60 degree 810nm LED, 90 degree 810nm LED ect. Nthawi zambiri, 940nm LED imapakidwa ndi 5mm kudzera-dzenje kukula kwa LED kapena vuto lina la SMD LED. Koma polojekiti ina, anthu amayenera kugwiritsa ntchito mandala okulirapo kuti awonjezere kuwala. Mukufuna zina za 810nm LED zokhala ndi mpikisano wokwanira? Lumikizanani nafe tsopano!

- Kukula kwa 3 mm IR Kupyola mu dzenje la LED -

* Mlanduwu ukupezekanso ndi ma LED ena, monga: 5mm wobiriwira kudzera mu dzenje la LED, UV LED, 660nm LED, 940nm LED, 5mm buluu kudzera mu dzenje la LED, chikasu cha LED, amber LED ect *

- Kugwira Ntchito Pabowo IR IR -

* Mitundu pachithunzicho idatengedwa ndi kamera, chonde tengani utoto weniweni monga muyezo.
