Makhalidwe a Mikanda ya Nyali ya Infrared ya LED

1. Mawonekedwe a mikanda ya nyali ya infrared ya LED: Mikanda yowoneka bwino ya nyali ya infrared ya LED ndi yofanana ndi mawonekedwe a mikanda yowunikira ya LED, koma kuwala kwa infrared kumaperekedwa. Mphamvu yake yogwira ntchito nthawi zambiri imakhala 1.4V, ndipo mphamvu yogwirira ntchito nthawi zambiri imakhala yochepera 20mA. Kuti azolowere osiyana voteji ntchito, nthawi zonse chingwe malire otaya kukana mu dera. Mukamagwiritsa ntchito mikanda ya nyali ya infuraredi ya LED kuti muwongolere chipangizocho, mtunda wake wowongolera ndi wolingana ndi mphamvu yoyambira. Kuti muwonjezere mtunda wowongolera wa kuwala kwa infrared, machubu oyambira a infrared (mikanda ya nyali ya infrared ya LED) amagwira ntchito ngati kugunda kwa mtima. Chifukwa mtunda wogwira ntchito wa kugunda kwa kuwala ndi wofanana ndi mitsempha ya kugunda. Mtunda woyambira. Njira yolimbikitsira IP ndikuchepetsa chiŵerengero cha pulse duty, ndiko kuti, m'lifupi lonse la T la kugunda, kuchepetsa chiwerengero cha pulse occupation kungathenso kuonjezera mtunda woyambira wa low-power infrared glow diode. The general infrared light emitting diode amagawidwa m'magulu atatu: mphamvu yaying'ono, mphamvu yapakatikati ndi mphamvu yayikulu. Kuti kuwala kwa infuraredi -emitting diode kupangike, ingowonjezerani ma frequency pulse voltage kwa dalaivala. Pamene infuraredi kuwala -emitting diode zimatulutsa infuraredi kulamulira zida, zida ankalamulira ndi lolingana infuraredi photoelectric kutembenuka zigawo zikuluzikulu, monga infuraredi kulandira diode, infuraredi kulandira mutu, kuwala -tcheru triode, etc. Pali njira ziwiri zoyambira ndi kulandira ma infrared, zomwe ndi zolunjika komanso zowonekera. Direct amatanthauza malekezero wachibale wa kufala ndi kulamulira zinthu kufala diode ndi kulandira diode ndi kulandira diode, amene ali mtunda wina ndi mzake; kusinkhasinkha kumatanthawuza kufanana kwa diode ndi diode yolandira. Mukakumana ndi reflex, landirani diode pokhapokha nditalandira infuraredi yowunikira. Chachiwiri, malinga ndi mawonekedwe a mikanda ya nyali ya infuraredi ya LED, malinga ndi kutalika kosiyanasiyana kuti mupeze ntchito zambiri: 1. Wavelength: 808nm, zida zamankhwala zogwiritsidwa ntchito, kulumikizana kwa kuwala kwa danga, nyali zowunikira za infuraredi, nyali zolimba zapampu za laser; Wavelength: 830nm, yoyenera makina osinthira makadi othamanga kwambiri; 3. Wavelength: 840nm, yogwiritsidwa ntchito pamakamera oyang'anira, mtundu wosinthidwa kukhala wopanda madzi; 4. Wavelength: 850nm, yogwiritsidwa ntchito poyang'anira makamera, kuwombera kwa digito, kuyang'anira, Louyu intercom, anti -kuba, anti -kuba Alamu, infrared madzi; 5, kutalika kwa mafunde: 870nm, oyenera kuyang'anira makamera m'malo akuluakulu ogulitsa ndi m'mphambano; 6. Palace: 940nm, woyang'anira woyenera, monga woyang'anira zipangizo zapakhomo.
