Ithini i-voltage evamile yomugqa wesibani se-LED?
- Ibanga le-voltage ye-lamp strip
Umugqa wokukhanya, owaziwa nangokuthi umugqa wokukhanya we-LED, ungumkhiqizo okhanyayo onezinzuzo zobuhle, ukonga amandla, impilo ende, ukuphepha nokuthembeka. Isetshenziswe kabanzi ekukhanyisweni kwezentengiselwano, ukukhanyisa kwasekhaya, imidlalo ye-e-sports, ukusebenza kwesiteji neminye imikhakha. Ngokuya ngohlobo nesimo sohlelo lokusebenza lomugqa wokukhanya, i-voltage yayo nayo iyahlukahluka.
Ama-voltages ajwayelekile we-lamp strip yi-12V kanye ne-24V. Ububanzi be-voltage yemigqa yesibani engu-12V yi-9V-14V, futhi ububanzi be-voltage yemigqa yesibani engu-24V yi-20V-28V. Kumele kuqashelwe ukuthi uhla oluthile lwe-voltage lwamamodeli ahlukene wezintambo zokukhanya lungase luhluke, futhi udinga ukukhetha ngokusekelwe ezidingweni zangempela lapho uthenga.
- Umthelela we-voltage emigqeni yokukhanya
Ama-voltage ajwayelekile okusebenza emigqeni ye-LED
Imigqa ye-LED yenziwe ngama-diode amaningi akhipha ukukhanya, ngalinye line-voltage engaba ngu-2 volts. Ngakho-ke, i-voltage yokusebenza yomugqa wokukhanya we-LED incike enanini lama-diode akhipha ukukhanya akha umugqa wokukhanya. Ngokuvamile, i-voltage yemigqa ye-LED ingama-volts angu-12 noma ama-volts angu-24.
Njengoba i-voltage yokusebenza yemigqa yokukhanya ye-LED iphansi, ukunikezwa kwamandla okukhethekile kuyadingeka. Ngokuvamile, ugesi we-LED oshayelayo unomsebenzi wokuguqula i-alternating current ibe yamanje eqondile, okungukuthi, ukuguqula amandla amakhulu (imvamisa engu-220V noma i-110V) ibe amandla kagesi kanye nawamanje adingwa umugqa wokukhanya we-LED.
Ububanzi be-voltage yomugqa wokukhanya bubaluleke kakhulu. Kuzothinta ukukhanya, amandla, ukukhiqiza ukushisa, impilo yesevisi, njll. komugqa wokukhanya. Ngokuvamile, umugqa wokukhanya we-24V wobude obufanayo uyakhanya futhi unamandla kakhulu kunomugqa wokukhanya we-12V, kodwa futhi ukhiqiza ukushisa okwengeziwe futhi ufinyeze impilo yayo yesevisi ngokufanele. Imichilo yokukhanya engu-12V ifaneleka kakhulu izinjongo zokukhanyisa nokuhlobisa, kuyilapho imichilo yokukhanya engu-24V ifaneleka kakhulu ekukhanyisweni kwezigcawu zendawo enkulu nezindonga zangemuva.
- Izimo zohlelo lokusebenza
Ngenxa yokuthi amapheshana akhanyayo anemibala ehlukahlukene, izinguquko, futhi anganwetshwa ngokuguquguqukayo, manje asetshenziswa kabanzi ekuhlobiseni, ekukhanyeni, ekukhanyeni nakwezinye izinkambu.
- Izindawo zokukhanyisa zezentengiso: njengenxanxathela yezitolo, izindawo zokudlela, izikwele, iminyuziyamu, njll.
- Izindawo zokukhanyisa ekhaya: njengekhishi, igumbi lokuhlala, igumbi lokulala, iphasishi, njll.
- Izindawo zegeyimu nezemidlalo ye-elekthronikhi: njengezindawo zokudlela ezinetimu ye-e-sports, amahholo emidlalo, amahholo e-e-sports, njll.
- Izindawo zokusebenza zesiteji: njengamahholo okudansa, amakhonsathi, izindawo zomshado, njll.
Ngamafuphi, ububanzi be-voltage yemigqa yokukhanya buhlukile futhi izikhathi ezisebenzayo nazo zihlukile. Lapho uthenga imichilo yokukhanya, udinga ukuhlaziya ngokucophelela izidingo zakho zokusebenzisa bese ukhetha umkhiqizo ofanelana nawe.
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.
