Ubuhlalu besibani se-LED Thenga Ubuhlalu Besibani Bama-LED Ezintathu Ngokungaqondi Okukhulu

Ukungaqondi kahle kuqala, ithemba lempilo yangempela yenkonzo liphezulu, umenzi wobuhlalu besibani se-LED ulindele ukuthi impilo yobuhlalu besibani se-LED ifinyelele amahora ayi-100,000. Kodwa-ke, njengayo yonke imithombo yokukhanya eyisisekelo, ukukhanya kokukhanya kobuhlalu besibani se-LED nakho kwehlile ngokuhamba kwesikhathi. Ngakho-ke, nakuba isikhathi sokukhanyisa ubuhlalu besibani se-LED singaba side kakhulu, i-MTBF akuyona ukuphela kokucatshangelwa kokunquma impilo yesevisi. Ukubola kobuhlalu besibani se-LED kuthinteka ezimweni eziningi zemvelo ezifana nezinga lokushisa lemvelo, umswakama kanye nokukhipha umoya. Umthelela wokuwohloka okuqhubekayo nawo uyathinteka ekulawuleni, ukubusa kwesayensi eshisayo, izinga lamanje, kanye nokucatshangelwa kokunye ukuklama okuningi kukagesi. Abathengisi abaningi bangase banikeze ulwazi oluthile kumakhasimende lapho bethengisa ubuhlalu besibani se-LED, okubangela ukudukisa, njengempilo yesevisi yobuhlalu besibani se-LED emahoreni angu-100,000. Amahora ayi-100,000 lapha asho ukuthi umenzi ulindele impilo yempilo yoMbani we-LED. Kodwa-ke, njengomthombo wokukhanya wokukhanyisa, ukukhanya kwezibani kunenqubo yokubola kancane kancane ibe mnyama (njengokukhanya kwelanga, izibani zokulondoloza amandla). Le nqubo ibizwa ngokuthi ukubola kokukhanya. Ngakho-ke, lapho abathengi bethenga ubuhlalu besibani se-LED, kufanele banake izinga layo lokukhanya, bangasebenzisi isikhathi, futhi abathengi ngeke balindele isikhathi sokuphila sangempela. Ukungaqondi kahle 2, hlukanisa i-engeli yokukhanya yangempela njenge-engeli ewusizo yobuhlalu besibani se-LED ibe i-engeli ewusizo kanye ne-engeli yokukhanya yangempela. Injongo yenani eliqondiwe yenani lamandla e-axial lokukhanya-okukhiphayo amandla i-engeli ewusizo ene-engeli ye-axial ekhipha ukukhanya (indlela). Izikhathi ezimbili i-engeli ye-engeli enguhhafu -value iwumbono (noma i-semi -power angle) i-engeli yokukhanyisa yangempela. Kusukela ku-engeli yohhafu wamandla e-axial ngenxa yokuthi ukukhanya kubuthakathaka kakhulu kuhlelo lokusebenza lwangempela, akubalwa ku-engeli ewusizo. Ngakho-ke, abathengi kufanele banake i-angle yokukhanyisa yangempela yomkhiqizo lapho bethenga imikhiqizo. Lapho ubala inani lemikhiqizo esetshenziswe kuphrojekthi, isekelwe engeli langempela lokukhanyisa. Ukungaqondi kahle 3, ukuphakama kokukhanya, ukuphakama kokukhanya kobuhlalu besibani se-LED nokuqina kokukhanya, futhi amandla okukhipha ukukhanya asho amandla okukhipha ukukhanya kwethagethi yomugqa wendlela (kuya epayipini elikhanyayo eliyicylindrical lisho i-axis) Ukukhanya okukhanyayo ukukhanya kwekhandlela (CD). Ngenxa yokuthi ubukhulu obukhanyayo bobuhlalu besibani se-LED buncane, amandla okukhipha ukukhanya avame ukusebenzisa amayunithi. Ngokuvamile, umthombo wokukhanya uzokhipha ukukhanya kwawo kuye ekuqondisweni okuhlukile kobuhlalu besibani se-Domestic LED obunamandla ahlukene. Ngokombono wokuthi bangaki umsebenzi owenza amandla ngesikhathi esifanayo, i-current iyashesha, yamanje iyashesha, ugesi yinkathi yamandla; i-curse ihamba kancane, amandla kagesi mancane, noma lapho umsinga wenza umsinga, ugesi uba mkhulu, ugesi uba mkhulu. Ebuhlaluni besibani se-LED, amandla aphezulu, ayanda ukukhanya komkhiqizo. Ukuthatha ubuhlalu besibani se-LED obuthathu obukhanyayo obukhanyayo be-Yimei Electronics njengesibonelo, lapho ukukhanya kwe-axial kungu-1200mcd, okwamanje kungu-40mA futhi amandla angu-0.48W; Kuyabonakala ukuthi amandla ezibani ezimbili ngaphansi kokukhanya ahlukile. Ngakho-ke, lapho abathengi bethenga ubuhlalu besibani se-LED, kufanele banake ukukhanya kwe-axis yayo, hhayi amandla. Isihloko sivela kubuhlalu besibani se-LED http://.
