I-LED Lamp Bead Chip Recognition I-LED Isibani Ubuhlalu Ukugqama Isikhundla

Ama-chips wesibani se-LED ahlukaniswe ngama-chips we-LED wamandla amancane, ama-chips e-LED anamandla aphakathi nendawo, kanye ne-chip ye-LED yamandla yonyaka. Usayizi othize we-chip ye-LED yobuhlalu be-LED uncike ezingeni langempela lokukhiqiza lomkhiqizi womkhiqizo we-chip ye-LED yobuhlalu obuhlukile, futhi azikho izidingo ezithile. Uma nje inqubo idlula, i-chip ye-LED yobuhlalu ingakhuphula ukuphuma kweyunithi futhi inciphise izindleko, futhi umsebenzi wamandla obonakalayo ngeke uguqule isisekelo. Ukusetshenziswa kwamanje kwama-chips wesibani se-LED empeleni kuhlobene nokuminyana kwamanje kokugeleza ku-chip. Ukusetshenziswa okuncane kwe-chip kuphansi, i-chip iphezulu okwamanje, futhi ukuminyana kweyunithi yamanje kubi ngokuyisisekelo. Uma ukusetshenziswa kwamanje kwe-chip ye-10mil kungu-20mA, khona-ke i-chip engu-40mil ingasebenzisa i-current ukuze ikhuphuke izikhathi ezingu-16, indlela yokuhlola izibani ze-LED ngu-320mA. Kodwa ukushiswa kokushisa kobuhlalu bezibani ze-LED kuyindaba ebalulekile esiyicabangelayo, ngakho-ke i-high -current high -current ye-chip iphansi kunokusebenza okuphansi kwamanje kokuphansi kwamanje kuma-chips amancane. Ngaphezu kwalokho, njengoba indawo ikhula, ukumelana kwe-chip kuzoncishiswa, ngakho-ke i-voltage yesiqondiso esihle izowa. I-chip yesibani se-LED yamandla yonyaka endala esetshenziselwa ukukhanya okumhlophe ngokuvamile ibonakala emakethe ku-40mil. Ngenxa yokuthi ukuguqulwa kokukhanya kokukhanya ngokuvamile kungaphansi kuka-50%, amandla omnyango womnyango azoguqulwa abe amandla okushisa, ngakho-ke ukuchithwa kokushisa kwamandla we-LED isibani se-chip chip kubaluleke kakhulu.
