Ingabe imichilo yokukhanya ye-LED ingasikwa?
Ingasikwa. Isekhethi yomugqa wokukhanya we-LED yakhelwe ngochungechunge/uxhumano oluhambisanayo, kodwa imithetho yokuthi ingasikwa kanjani ihlukile. Lokhu kuncike ekwakhiweni komugqa wokukhanya we-LED. Ngokuvamile, abakhiqizi bemichilo yokukhanya ye-LED bakhiqiza izibani ze-LED. Uma kukhulunywa ngemichilo, banemithetho yesekethe yokwenza ngokwezifiso imichilo ye-LED ngokuya ngezidingo. Ubuhlalu besibani se-LED bubuye busetshenziswe ngokwezidingo. Ubuhlalu besibani se-LED bunemikhawulo ehlukene yokusebenza kwamandla kagesi, ngakho-ke imichilo yesibani ye-LED isuselwa ku-voltage yobuhlalu besibani obusetshenzisiwe. Okuhlukile, isikhundla sokusika sizophinde sihluke.
Isibonelo 1: Imichilo yokukhanya ye-LED engu-12-volt ivamise ukuza ngokucaciswa okubili, nesibani esisodwa nokusikwa okukodwa, noma amalambu amathathu nokusikwa okukodwa.
- Okokuqala, sizokwethula indlela yesibani esisodwa sokusika eyodwa. Isebenzisa ubuhlalu belambu le-voltage esebenzayo engu-9-volt. Ngale ndlela, ubuhlalu besibani se-9-volt kanye ne-resistor kungaxhunywa ochungechungeni ukuze kuncishiswe i-voltage, futhi ukusika kwesibani esisodwa kungafinyelelwa.
- Okungukuthi ukusika izibani ezintathu kanyekanye. Usebenzisa ubuhlalu bamalambu obu-3-volt obuthathu. Lezi zibani ezintathu zixhunywe ochungechungeni nge-resistor ukunciphisa i-voltage, ukuze izibani ezintathu zingasikwa endaweni eyodwa.
Isibonelo sesi-2: Kuningi ukucaciswa kwemichilo yokukhanya ye-LED engu-24-volt. Izikhundla lapho amalambu amalambu e-LED angu-24-volt angasikwa khona emakethe zingakukhazimula. Imichilo yokukhanya ye-24-volt ye-LED ihlanganisa isibani esisodwa-i-cut-one-cut, i-lamp-one-cut, kanye ne-3-lamp-one-cut. Sika, amalambu ayisithupha kanye nokusikwa okukodwa, nezibani eziyisikhombisa nokusikwa okukodwa.Ngaphandle kokuchitha isikhathi, ake ngikwethule kuwo wonke umuntu kuqala.
- Ukusebenza okukodwa kwesibani esisodwa. Isebenzisa ubuhlalu belambu le-voltage esebenzayo engu-18V kuya ku-21V kanye nezinto eziphikisayo ezixhunywe ochungechungeni ukuze kuncishiswe i-voltage. Lokhu kungafeza ukusebenza kwesibani esisodwa-off.
- Ungawenza kanjani amalambu amabili kanye nomugqa owodwa osikiwe we-LED? Usebenzisa ubuhlalu belambu lelambu le-voltage elisebenza ngama-voltage amabili nama-resistors axhunywe ochungechungeni ukuze anciphise i-voltage, ukuze kufezwe umklamo onamalambu amabili kanye nokusika okukodwa.
- Ungawenza kanjani amalambu amathathu kanye nomugqa owodwa osikiwe we-LED? Usebenzisa ubuhlalu bezibani ezintathu nge-voltage esebenzayo ye-volts engu-6 futhi uzixhuma ochungechungeni nama-resistors ukuze anciphise i-voltage, ukuze kutholakale umklamo we-lamp-one-cut one-cut.
- Umugqa wokukhanya we-LED onamalambu ayisithupha-uwodwa usebenzisa ubuhlalu besibani obungu-3-volt obuyisithupha. Ubuhlalu bamalambu ayisithupha kanye nama-resistors axhunywe ochungechungeni ukuze kuncishiswe i-voltage, ukuze umklamo we-light-cut one-cut eyodwa ungafinyelelwa.
- Kuthiwani ngalena enamalambu ayisikhombisa kanye nokusikwa okukodwa? I-strip yokukhanya ye-LED enezibani eziyisikhombisa-ingxenye eyodwa iqukethe ubuhlalu belambu obuyi-3-volt obuyisikhombisa kanye nezinto eziphikisanayo ezixhunywe ochungechungeni, ukuze kutholakale umklamo wokusika owodwa wezibani eziyisikhombisa.
Eqinisweni, imichilo yokukhanya ye-LED izomakwa ekuqaleni komklamo. Intambo ngayinye yezibani izoba nomugqa oqondile lapho ingasikwa khona. Udinga kuphela ukuyisika kule ndawo. Uma indawo yokusika ingekho emgqeni oqondile, izobangela ukuthi isethi yobuhlalu besibani se-LED isikwe. Asikho isimo sokukhanya.
Ngezansi ngizokukhombisa ezinye izithombe zemikhiqizo yenkampani yethu ukukusiza ukuhlonza izindawo zokusika zamapheshana okukhanya kwe-LED.
Izinyathelo zokuphepha zokusika
- Lapho usika imichilo yokukhanya kwe-LED, sicela uqaphele ukuthi kufanele isikwe iqonde.
- Naka ukusikeka okuhlukene kwamapuleti omugqa wokukhanya we-LED. Ukuze kuhlangatshezwane ne-thermal conductivity nokusebenza kokukhipha ukushisa kwemichilo yokukhanya kwe-LED, imichilo yokukhanya ye-LED eminingi manje isebenzisa ama-aluminium substrates amaningi. Aluminium substrates kukhona conductive. Lapho ugunda, Kungenzeka kakhulu ukuthi kubangele isifunda esifushane, ngakho-ke sidinga ukuhlola ukuthi i-foil yethusi ixhunywe ku-substrate ye-aluminium ngezansi ngemva kokusika. Uma izixhumanisi zixhunyiwe, sidinga ukuzihlukanisa ukuze kukhanye ukukhanya kwe-LED.
Ubuchwepheshe be-LED bushintshe indlela esikhanyisa ngayo amakhaya ethu namabhizinisi. Akugcini nje ngokuletha ukusebenza kahle kwamandla ekukhanyeni, futhi kuthuthukisa ikhwalithi yokukhanya, kukwenze kuhambisane nezimo ezihlukahlukene. I-LED imele i-light-emitting diode, idivayisi ye-semiconductor ekhipha ukukhanya lapho ugesi udlula kuyo. Ubuchwepheshe be-LED busebenza kahle kakhulu kunezibani zendabuko ze-incandescent nezibani ze-fluorescent. Kodwa asebenza kahle kangakanani ama-LED?
Enye yezinkomba eziyinhloko zokusebenza kahle kokukhanyisa ukusetshenziswa kwamandla. Ubuchwepheshe be-LED baziwa ngokusetshenziswa kwayo okuphansi kwamandla, okwenza kube ukukhetha okuthandwayo kokukhanyisa kwezindawo zokuhlala nezokuhweba. Eqinisweni, izibani ze-LED zonga amandla afika ku-80% ngaphezulu kunezibani zendabuko ze-incandescent futhi cishe ngo-20-30% ngaphezu kwezibani ze-fluorescent. Ukwehliswa kokusetshenziswa kwamandla akwehlisi nje kuphela izikweletu zikagesi zabathengi kodwa futhi kusiza ukunciphisa kakhulu ukukhishwa kwekhabhoni, okwenza ubuchwepheshe be-LED bube inketho yokukhanyisa evumelana nemvelo.
Sekukonke, ubuchwepheshe be-LED busebenza kahle kakhulu mayelana nokusetshenziswa kwamandla, ukuphila isikhathi eside, ukuphuma kokukhanya nokulawula. Ukusetshenziswa kwayo okuphansi kwamandla, impilo ende, ukukhanya okuphezulu kanye nokusebenza okukhanyayo kuyenza ibe ukukhetha okuhle kakhulu kokukhanyisa uma kuqhathaniswa nezibani zendabuko ze-incandescent kanye ne-fluorescent. Njengoba isidingo sezixazululo zokukhanyisa ezonga amandla nemvelo sikhula, ubuchwepheshe be-LED kulindeleke ukuthi bubambe iqhaza elibaluleke kakhulu ekulolongeni ikusasa lokukhanyisa.
