Awoodda sare ee IR LED.
Waxaan ku siinnaa alaab tayo sare leh IR LED leh kala duwanaansho, sida: 0.5W 940nm Awoodda sare ee IR LED, 1w 940nm Awoodda sare ee IR LED, 2W 940nm Awoodda Sare ee IR LED, 2w 940nm Awoodda Sare ee IR LED, 3W 940nm Awoodda Sare ee IR LED, 0.5W 850nm Awoodda sare ee IR LED, 1w 850nm Awoodda sare ee IR LED, 2W 850nm Awoodda sare ee LED LED, 3W 850nm Awoodda sare ee IR LED iwm.
Haddaba waa maxay farqiga u dhexeeya 940nm iyo 850nm?
940nm infrared LEDs gabi ahaanba lama arki karo indhaha qaawan, taas oo macnaheedu yahay inaadan arki karin in 940nm shaqeynayo iyo in kale. Ilaa aad ka daawato aaladda qaarkood (sida kamaradda taleefanka), oo tusi doonta xoogaa midab guduudan ama midab cad leh.
LED -yada 850nm infrared waxay leeyihiin casaan aad u yar marka uu shaqeynayo, taas oo macnaheedu yahay inaad arki karto haddii 850nm LED uu shaqeynayo.
Isla awooddaas, xoojinta shucaaca ee 850nm waxay ka sarreysaa 940nm. Dabcan, 940nm sidoo kale waxay leedahay faa'iidooyin u gaar ah. Waa isha qaawan ee aan lagu kala sooci karin shaqada ama shaqada, sidaa darteed, codsigeeda ayaa si weyn looga adeegsaday suuqyo badan oo gaar ah xilligan casriga ah.

Intaa waxaa dheer, waxaan sidoo kale ku darnaa muraayadda dusha sare ee SMD LED, taas oo ka dhigi karta LED-ka SMD inuu yeesho xagal sida kuwa loo yaqaan 'Thought-hole LED', oo aan ugu yeernay ' IR Domed LEDs'.
Tusaale ahaan: 850nm Awoodda sare ee IR LED leh 30 darajo, 850nm Awoodda sare ee IR LED leh 60 darajo, 850nm Awoodda sare ee IR LED leh 90 darajo, 940nm Awoodda sare ee IR LED leh 30 darajo, 940nm Awoodda sare ee IR LED leh 60 darajo, 940nm Sare awoodda IR LED leh 90 darajo, iwm.Waxaan sidoo kale habayn karnaa caaryada ledns -ka sida aad u baahan tahay xagal.
Waxaan soo saarnaa oo iibineynaa Awoodda Sare ee IR LED, oo la socota hirarka dhererka 680nm-1550nm.
Qeybtaan, waxaan inta badan soo bandhignaa labada nooc ee mowjadaha hirarka: 940nm IR LED iyo 850nm IR LED. Labadan mowjadood ee mawjadaha ayaa ah kuwa ugu badan ee loo adeegsado kormeerka infrared. Dhammaantood waxaa loo isticmaali karaa in lala socdo alaabta.
