940nm IR LED - 3014 SMD LED

Suuqayaga LED -ka, waxaan ugu yeeri karnaa LED infrared sida IR LED ama LED IR emittier. Caadi ahaan dhererka hirarka waa 850nm ama 940nm, waxaa sidoo kale jira hirar kale sida 880nm LED, 900nm LED, 970nm LED, 980nm LED ect. Markaa maxay ku kala duwan yihiin 940nm IR LED iyo 850nm IR LED?

1. 850nm infrared LED ama 940nm infrared LED waxaa loola jeedaa dhererka hirarka ee ka soo baxa chip LED -ka. Unuggu waa nm, oo iska leh iftiinka infrared. Waxay marka hore muujinaysaa farqiga u dhexeeya mawjada
2. Guud ahaan marka la eego, qiimaha dhererka mawjadda sare, ayaa hoos u dhigaysa hoos u dhaca danab hore VF hoos xaaladda isla hadda. Marka la eego xaaladda 20MA ee hadda, qiimaha VF ee 850nm IR LED (850nm dhex-dalool IR LED ama 850nm SMD LED) wuxuu ku saabsan yahay 1.35-1.55V, iyo qiimaha VF ee 940nm IR LED (940nm dhex-dalool IR LED ama 940nm SMD LED) Qiyaastii 1.10-1.25V, dabcan, qiimaha VF wuu ka duwanaan doonaa iyadoo ku xiran hadba hadda
3. Laydhka 850nm wuxuu leeyahay dillaac guduud ah iyo 940nm LED ma laha dillaac cas. Waxa loogu yeero dilaaca cas waxaa loola jeedaa dhibco guduudan oo muuqaal ahaan ka muuqda chip-ka marka laambadda infrared-ku shaqaynayso. Markaa haddii aad u baahan tahay inaad dhuumato, isticmaal 940nm SMD LED ama 940nm LED Lamp waa doorasho wanaagsan, laakiin qaar Macmiilku wuxuu isticmaali doonaa koloydhka madow 850nm LED si uu u daboolo xaaladda dilaaca cas, laakiin haddii aad fiiro gaar ah u yeelato, casaanka dillaaca ayaa weli muuqda

LED -kan IR wuxuu helay cabbir yar: 3.0mm*1.4mm*0.8mm. La mid ah kuwa kale ee SMD LED, Tani waa sababta ay dadku ugu yeeraan 3014 SMD IR LED.

Awoodda hooseysa IR LED waxaa lagu sameeyay cabbir yar oo ah chip LED, sida 10 mil, 12 mil. 14 mil, 16 mil ect. SMD IR LED wuxuu noqonayaa mid caan ah, sidaa darteed tirada warshadda IR Chip Chip -ku waxay sii kordhaysaa sanadahan. Calaamadda chip -ka ugu caansan waa Epistar, Tyntek ect. Chip -kaas LED -ku wuxuu helay waxqabad ka kaamil badan kan kale, taasina waa sababta ay u noqon karto xulashadayada ugu horreysa ee loogu talagalay IR LED -ka.
