Diodo argitsuaren parametro teknikoaren deskribapena

Argi-igorlearen diodo ezaguna 1.6V-2.1V-ra jaisten da, eta 5-20mA LED-ren lan-korrontearen ezaugarriak 1. Muga-parametroaren esanahia (1) Promesa energia-kontsumoa PM: LED-en bi buruak DC tentsio-tentsioari gehitzeko konpromisoa Bertatik igarotzen den gau baliorik zaharrena. Gurutzatu balio hau, LED sukarra eta suntsipena. (2) DC korronte positiboa IFM: agindutako datu-korronte garrantzitsuena. Balio honek diodoa suntsitu dezake. (3) Alderantzizko tentsioa VRM: gehitzeko agindutako alderantzizko tentsio zaharrena. Balio honekin, argia igortzen duen diodoa hautsi eta suntsitu daiteke. (4) TOPM: argi-igorlearen diodoaren tenperatura-eskalak normaltasunez funtziona dezake. Tenperatura horren azpitik edo gorago, argi-igorlearen diodoak ez du behar bezala funtzionatuko, eta efektua murriztu egiten da. 2. Parametro elektrikoen garrantzia (1) Lan-korronte positiboa IF: Diodoaren distira normalaren korronte positiboari egiten dio erreferentzia diodo distiratsuan. Erabilera errealean, behar izanez gero aukeratu behar duzun aukeratu beharko zenuke ·ifm azpian. (2) Lan-tentsio positiboa VF: Parametroen taulan emandako lan-tentsioa aurrerako korronte jakin baten pean lortzen da. Normalean IF = 20mA denean neurtzen da. Diodo argitsua VF funtzionamendu-tentsioan dago 1,4 3V-tan. Kanpoko tenperatura igotzen denean, VF lurreratu egingo da. (3) V-I ezaugarria: argi-igorlearen diodoaren tentsioaren eta korrontearen arteko erlazioa balio jakin bat baino txikiagoa denean (atalasea deritzona), korrontea oso txikia da eta ez du argirik igortzen. Tentsioak balio jakin bat hartzen duenean, aurrerako korrontea arina da tentsioarekin eta distira. Nola kendu I argi-hodiaren tentsio positiboa, alderantzizko korrontea eta argi-tutuaren alderantzizko tentsioa kendu ditzaket V-LED lanpara-alea nola kendu. Hodi argitsu positiboa alderantzizko ihes-korrontea IR
